Automatic oil pressure gating device

The present invention provides an automatic oil pressure gate control device, especially an automatic oil pressure gate control device with automatic control effect and relatively energy saving.

Press, the door bow is a device that is used to allow the door leaf to be automatically closed after the door leaf is opened. There are many types of operation of the door bow, such as spring drive, hydraulic drive, electronic drive and so on.

And in many public places, since the number and types of people entering and leaving are also various, if everyone who enters and exits needs to push or touch the door, it is easy to make this action a source of disease infection. If it is in an area with severe epidemics, it may become a serious breach in epidemic prevention.

However, ordinary door bows usually do not have the effect of automatic opening. When automatic opening is required, related electronic equipment will be installed on the door leaf. If you want to use the door bow directly to achieve automatic opening, you need A torque type motor is additionally installed on the door bow to directly rotate the door leaf. The above-mentioned automatic opening method requires a large amount of torque and electricity, and therefore naturally consumes more energy.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and related manufacturers in the industry are eager to research and improve.

Therefore, in view of the above deficiencies, the inventor of the present invention has collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trial production and modification, before designing this kind of automatic opening and achieving The inventor of the patent for the automatic hydraulic door control device with energy saving effect.

The main purpose of the present invention is to achieve automatic opening through the combination of the power element and the oil body. It can reduce the power used and have the advantage of energy saving.

In order to achieve the above object, the main structure of the present invention includes: a main body, a first space formed in the main body, a second space formed in the main body, a push valve movably penetrated in the first space, a via A first right space separated by the push valve, a first left space separated by the push valve, a driving valve movably arranged in the second space, a second right space separated by the driving valve, a driving valve The separated second left space, a first communication part formed on the main body and connected to the first right space and the first left space, a first one-way valve set in the first communication part, a first communication part formed in the The main body is provided with a second communication portion for communicating with the second right space and the second left space, a control valve provided on the second communication portion, and a control valve formed on the main body for communicating with the first left space and the second left space. a left communication part, a right communication part formed on the main body and connected to the first right space and the second right space, a left one-way valve arranged in the left communication part, a power element arranged on the main body and connected to the push valve , a transmission shaft which is inserted into the main body and engages with the driving valve, an elastic element which is arranged in the second right space and interferes with the driving valve, and a control device arranged at the side of the main body, wherein the first space and the second right space The second space will be filled with oil.

With the above structure, the user can connect the main body to the door leaf, and when the door leaf is pushed, the drive shaft will be rotated. Relatively speaking, when the drive shaft is rotated, the door leaf will be pushed to rotate.

In this way, when the user needs to open the door, he can control the power member to act through the control device, so as to make the push valve move in the first space, and push the oil in the first left space into the second left space through the left communication part. In the space, and while the oil body is flowing, the oil body will not be pushed back into the first space through the left communication part due to the restricting effect of the left one-way valve.

When the oil body is pushed into the second left space, it will push and drive the valve to move in the second space. When the valve is driven to move, it will squeeze the elastic element and drive the transmission shaft to rotate, so as to push the door leaf to rotate to achieve automatic opening. Effect. At this time, since the control valve will close the second communication portion, the oil in the second right space will be supplemented into the first right space through the right communication portion due to being squeezed.

When the door leaf is opened to a predetermined position, the power member will act in the opposite direction, so that the push valve moves in the direction of the first right space to achieve the effect of return. At the same time, in the second space, because of the relationship between the left one-way valve and the control valve, the oil in the second space cannot flow, so only the oil in the first right space will push the first one-way valve to It is supplemented into the first left space through the first communication part. Since the oil in the second space cannot flow, the driving valve and the transmission shaft will not have any action, so the door leaf can be kept in an open state.

When the user needs to close the door, the control valve can be manipulated to open the second communication part , at this time, the oil in the second left space can enter the second right space through the second communication part, and the elastic element can release the accumulated elastic force to push the driving valve back to its original position, thereby driving the The drive shaft rotates to close the door leaf.

In this way, the effect of automatically opening and closing the door can be achieved by the above-mentioned method, and the torque and electric power required to be consumed can be reduced by the way of pushing the power element in conjunction with the oil pressure, so as to achieve the advantage of saving energy.

With the above-mentioned technology, a breakthrough can be made to solve the problems of conventional door bows that cannot be automatically opened or consumes relatively energy, so as to achieve the practical progress of the above-mentioned advantages.

From the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the door 91 can be automatically opened and the advantages of energy saving can be obtained, and the detailed explanation will be described below.

Please also refer to Figures 1 to 10, which are three-dimensional perspective views to closed schematic diagrams (2) of the preferred embodiment of the present invention. As shown in the third figure, the main body 1 can be arranged on the door leaf 91, and the transmission shaft 7 can be connected with the door frame 92 by means of connecting rods.

When the user wants to open the door leaf 91, as shown in Figures 5 to 7, the user only needs to approach the control input device 82 (for example, let the input device 82 sense the identification card, directly input the password on the input device 82, or Using the switch button as the input device 82 for the user to press), the signal will be transmitted to the control device 81 . The control device 81 will control the power member 6 to open and act. In this embodiment, the power member 6 and the push valve 2 are connected to each other in a screw-locked manner. Therefore, when the power member 6 rotates, it will drive the push valve 2 to move toward each other. When the door 91 needs to be opened, the power member 6 will drive the push valve 2 to move in the direction of the first left space 111 . At this time, because the first communication portion 113 cannot move to the first right space 112 through the first communication portion 113 due to the relationship of the first check valve 51 , the oil body will push the left check valve. 53 and flows to the second left space 121 through the left communication portion 13 . When the oil body flows to the second left space 121 , it will push and drive the valve 3 to move in the direction of the second right space 122 . Since the driving valve 3 will move in the direction of the second right space 122, the area of the second right space 122 will be reduced, thereby pushing the oil in the second right space 122 to flow in other directions. Open to close the second communication portion 123, so that the oil in the second right space 122 can only flow in the direction of the first right space 112 through the right communication portion 14, and the oil in the first right space 112 can be replenished. Keep the oil in body 1 in a balanced state .

When the valve 3 is driven to move in the direction of the second right space 122 , the drive shaft 7 is driven to rotate and press against the elastic element 4 through the top pressing portion 32 to accumulate the elastic force of the elastic element 4 . When the transmission shaft 7 rotates, it will push the door leaf 91 to rotate, so that the effect of automatic opening can be achieved.

When the door leaf 91 is opened to the predetermined position, the control device 81 will control the power member 6 to act in the opposite direction, and as shown in Figure 8, thereby driving the push valve 2 to return to the original position to achieve the return effect. And in the process of moving, the control valve 52 will still block the communication effect of the second communication part 123, and because the left one-way valve 53 will prevent the oil in the second left space 121 from entering the first through the left communication part 13. In the left space 111, the oil bodies in the second left space 121 and the second right space 122 cannot generate any static state of flow, and the oil bodies in the second left space 121 and the second right space 122 cannot flow. Therefore, the driving valve 3 and the transmission shaft 7 cannot produce any action, so that the door leaf 91 can be kept open. The oil in the first right space 112 will push the first check valve 51 to enter the first communication portion 113 to be supplemented into the first left space 111 , so that the oil in the main body 1 is also kept in balance status.

The user can set the time for the door leaf 91 to remain open in the control device 81 , such as ten seconds, and when the time is up, the control device 81 will release the power of the control valve 52 so that the control valve 52 is no longer closed. The second communication portion 123 . As shown in the ninth and tenth figures, the oil in the second left space 121 and the second right space 122 can flow through the second communication part 123, so that the driving valve 3 can be driven in the second left space 123. The space 121 and the second right space 122 are moved. At this time, the elastic element 4 will release the accumulated elastic force to push and drive the valve 3 to move in the direction of the second left space 121 to drive the transmission shaft 7 to rotate in the opposite direction, thereby achieving the effect of closing the door 91 .

And because the driving valve 3 will squeeze the oil in the second left space 121, and the oil in the second left space 121 cannot enter the left communication part 13 because of the blocking of the left one-way valve 53, it will pass through the second left space 121. The second communication portion 123 enters the second right space 122 , so that the oil body in the second space 12 also maintains a balanced state.

In this way, the effect of automatically opening the door leaf 91 can be achieved by means of the power member 6 cooperating with the flow of the oil body, and because the opening operation is achieved through the mutual cooperation between the power member 6 and the oil pressure, and the door leaf 91 is kept in a state of continuous opening. , it is not necessary to make the power element 6 act continuously, it can be achieved only by using the hydraulic method, so it can also have the advantage of saving energy.

Furthermore, when the door 91 is normally closed, because the control valve 52 is in an open state, the oil in the second space 12 cannot flow arbitrarily, so that the second space 12 is in a static closed state, and further The drive valve 3 and the transmission shaft 7 cannot be moved or rotated at will, and the door leaf 91 cannot be rotated and opened at will, so that the effect of access control can be achieved. However, if the power is cut off due to an emergency such as a fire or an earthquake, the control valve 52 will not continue to block the communication effect of the second communication part 123, and the oil in the second space 12 can be arbitrarily The user can push the door leaf 91 to open at will, so at the same time, it can have access control effect at ordinary times, and can open the double safety function at will when a special dangerous situation occurs.

Please also refer to Figures 11 to 15, which are schematic cross-sectional views to schematic block diagrams (2) of still another preferred embodiment of the present invention. It can be clearly seen from the figures that this embodiment is different from the above-mentioned The embodiments are similar with minor differences, only a pressure valve 54a is provided on the first communication portion 113a, a push seal 21a is provided on the push valve 2a, and a drive seal 31a is provided on the drive valve 3a. The push seal of this embodiment The member 21a and the driving seal member 31a take a plastic ring as an example.

Therefore, the sealing effect of the push valve 2a and the drive valve 3a can be enhanced through the push seal 21a and the drive seal 31a, so that the effect of the oil pressure can be more stable.

In this embodiment, the input device 82a uses an infrared sensor as an example, and the main body 1a is disposed on the door frame 92a, and then the transmission shaft 7a is connected to the door leaf 91a through a connecting rod, so that as long as the user is close to the door body When the input device 82a senses the user, the control device 81a controls the power element 6a to open the door leaf 91a.

In normal use, the pressure valve 54a will cooperate with the first one-way valve 51a so that the oil in the first communication part 113a can only flow in the direction of the first left space 111a, and if the door 91a is blocked when it is opened ( If someone hits the door leaf 91a or encounters an obstacle), it can be matched as shown in Figure 15. At this time, the actuation of the transmission shaft 7a and the drive valve 3a will be hindered, so that the oil body cannot smoothly enter the second left space 121a At this time, since the pressure of the oil body in the first left space 111a will increase, the pressure valve 54a is pushed to open, so that the oil body in the first left space 111a can enter the first right space 112a through the first communication portion 113a in order to keep the oil in the main body 1a balanced, so that the transmission shaft 7a and the drive valve 3a do not continue to rotate, so as to prevent others from being hit or the chance of the main body 1a being damaged due to obstacles.

Please also refer to Figures 16 to 19, which are schematic cross-sectional views to schematic opening (2) of another preferred embodiment of the present invention. It can be clearly seen from the figures that this embodiment is the same as the above The above embodiments are similar with minor differences. In this embodiment, the transmission shaft 7b and the driving valve 3b are connected and driven by a cam, and the control device 81b is a control circuit board arranged next to the power element 6b, and the input device 82b is for security personnel. The control machine for control (a computer is used as an example in this embodiment) is not limited to indicate the positions and types of the control device 81b and the input device 82b.

And the door frame 92b is provided with a display device 83b connected to the control device 81b. The display device 83b in this embodiment takes a lamp disposed on the door frame 92b as an example. In this way, when the user wants to enter, the security personnel can first observe whether they can be released. If it is a person who can enter, the security personnel will press the input device 82b to transmit a signal to the control device 81b, which is the same as the above-mentioned embodiment. In the actuation mode, the power member 6b is used to link the valve 3b to move, and the drive valve 3b will drive the transmission shaft 7b to rotate through the cam drive, thereby driving the door leaf 91b to open. And when the door leaf 91b is actuated, the display device 83b will display different light signals according to different states of the door leaf 91b, such as green when the door is opened and red when it is closed, so that the user can know the actuation state of the door leaf 91b through the display device. .

However, the above descriptions are only the preferred embodiments of the present invention, which do not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the description and drawings of the present invention should be the same.
