Description

Lifting device for lift table

The present invention relates to a lifting device for a lift table.

The lift table is disposed on an industrial site or a school, and the user can work, learn, and the like on a flat table panel installed at the upper side thereof, and the height of the table panel can be adjusted.

As described above, the structure for adjusting the height of the table panel in the lift table is a lifting device for the lift table.

In detail, a lift table generally includes two pairs of lower frames placed on an installation surface thereof, an upper frame on which the table panel is placed, and two ends each connected to the lower frame and the upper frame, the ends being connected to each other. Includes legs

Gas cylinders or hydraulic cylinders are used as the operating member to allow the lift table of this structure to be raised and lowered smoothly with less external force. Each end of the operating member has one of the upper frame and the lower frame and one of the legs. It is made of a structure that connects one or a pair of legs to each other.

As an example of such a lift table, Patent Publication No. 10-2016-0100175 (name of the invention: desk capable of height adjustment), Patent No. 10-1575195 (name of the invention: table lift) and the like can be presented.

However, according to the conventional lifting table lift apparatus, each end of the operating member is configured to connect one of the legs and one of the upper frame and the lower frame, or to connect a pair of legs to each other, Each end must be connected to a frame or leg, respectively, and therefore, each end of the actuating member and a structure for connecting to the frame or leg must be applied to each end of the actuating member respectively, so that there are many additional structures for such a connection. As a result, the manufacturing cost of the lift table increases, and the increase in the number of parts causes frequent failures.

In addition, according to the conventional structure for attaching the auxiliary device for the lift table, when additional attachment to the auxiliary device such as the auxiliary table and the work order plate is required in addition to the table panel, a structure for additional attachment to the auxiliary device is not provided separately. Not only is it difficult to further attach to such an auxiliary device, but there is also a disadvantage that an integral additional attachment is not possible by using a separate fixing means.

In addition, according to a conventional lift table lift apparatus, the lift table is applied to other objects, for example, Patent Application Publication No. 10-2016-0111905 (Invention: Industrial shelf forming rack system and the industrial shelf forming rack system is applied to If there is no means to fix the lift table to other objects, it is necessary to fasten it with a screw, etc., so that both the lift table and other objects may be damaged, and it may be repeatedly removed. There is a disadvantage that no coupling can be made.

An object of the present invention is to provide a lifting device for a lift table having a concise structure in which a structure for connecting an operation member such as a gas spring and a hydraulic cylinder is minimized.

The roller members 156 and 158 are connected to the leg members 150 and, as the leg members 150 rotate, the upper frame 130 and the lower frame when the upper frame 130 is elevated. It may be moved along at least one of the (110).

In detail, the roller members 156 and 158 are rotatably connected to the lower portion of the second leg 152 and the lower roller 158 which can be moved along the lower roller moving holes 113 and 117. And an upper roller 156 rotatably connected to an upper portion of the first leg 151 and movable along the upper roller moving holes 133 and 137.

The lower roller 158 and the upper roller 156 are each configured as a pair, and are connected to each of the first leg 151 and each of the second leg 152 one by one.

The roller connecting shafts 155 and 157 connect a pair of rollers moved along the same frame among the upper frame 130 and the lower frame 110. That is, the upper one of the roller connecting shafts 155 and 157 155 connects the pair of upper rollers 156 to each other across the inside of the upper frame 130, and the roller connecting shaft ( The lower one of the 155 and 157 157 connects the pair of lower rollers 158 to each other across the lower frame 110.

The lower end of the first leg 151 is rotatably connected to the first leg connecting portions 112 and 116, which are one end of the lower frame 110, and the upper end of the first leg 151 is the upper portion. The upper and lower ends of the first leg 151 are disposed to be movable along the upper roller moving holes 133 and 137 when the frame 130 is elevated, and is disposed above the roller connecting shafts 155 and 157. It is connected to the 155, the upper end of the second leg 152 is rotatably connected to the second leg connecting portion 132, 136, which is one end of the upper frame 130, the second leg The lower end of 152 is disposed to be movable along the lower roller moving holes 113 and 117 when the upper frame 130 is lifted, and the lower end of the second leg 152 is connected to the roller connecting shaft ( 155 and 157 are connected to the lower one (157).

The upper ends of the pair of first legs 151 and the lower ends of the pair of second legs 152 are connected to each other by the roller connecting shafts 155 and 157, respectively. A pair of the upper roller 156 and a pair of the lower roller 158 are respectively connected to each end of the 157, so that the first leg 151 and the second leg 152 can be smoothly moved. In addition, each of the leg members 150 installed on both sides of the lower frame 110 and the upper frame 130 may be operated in conjunction with each other, so that the lifting of the upper frame 130 is more smoothly. Can be done.

The actuating members 160 and 165 are operated to smoothly raise and lower the upper frame 130, and one end of the actuating members 160 and 165 is connected to one of the roller connecting shafts 155 and 157. The other end portion of the operation members 160 and 165 is connected to a leg different from a leg to which the roller connecting shafts 155 and 157 are connected, among a plurality of legs constituting the leg member 150.

The actuating members 160, 165 comprise at least one of a gas spring and a hydraulic cylinder.

In the present embodiment, the upper portion of the operating member (160, 165) is arranged on the upper side of the roller connecting shaft (155, 157), that is, the upper end of the first leg (151) connected to each other Rotatably connected, and a lower portion of the actuating members 160 and 165 is rotatably connected to the second leg 152 below the point where the first leg 151 and the second leg 152 intersect. Connected. For example, when the actuating members 160, 165 are hydraulic cylinders, the cylinder body is connected to the upper one of the roller connecting shafts 155, 157, 155, and the piston is the leg member 150. Can be rotatably connected to the second leg 152.

A fixing groove 155a is formed in an upper portion 155 of the roller connecting shafts 155 and 157, and an upper portion of the actuating members 160 and 165 is upper of the roller connecting shafts 155 and 157. The fixing means 155b is coupled to the fixing groove 155a so that the state connected to the one disposed in the holding unit 155a is maintained.
