Abstract

The invention discloses a transverse two-section pushing buckle. In the buckle, a buckle rod arranged on a door sheet or a detachable shell is utilized to apply force along a first direction so as to push a latch body arranged along a second direction. The latch body is linked with a pushing component, when the latch body moves along the second direction, the pushing component pushes the latch body back and is fixed at a locking position, and meanwhile, the latch body is clamped with the buckle rod, so that the buckle is in a clamping state. When the buckle rod is pushed again along the first direction, the buckle rod drives the bolt body to move along the second direction to the maximum compression stroke, and drives the pushing component to release the lock of the bolt body, and the bolt body pushes the buckle rod to be disengaged from the lock of the bolt body, so that the buckle is in a release state. The thickness of the latch body configured along the second direction is far less than the width of the movement stroke, so that the thickness required by the buckle arranged on the device can be effectively reduced, and the latch body is applied to a miniaturized device.

Description

Horizontal two-stage push buckle

technical field

The invention relates to a buckle, in particular to a push-on type buckle whose thickness can be reduced by lateral movement.

Background technique

In common TVs, cabinets, etc., the door often needs a switch device. In order to facilitate the user's operation, a structure called a push-push buckle is often used. Press in one direction to lock the buckle, and then press the door in the same direction to unlock the buckle. This kind of force direction is the same as that of the locking buckle, and the vertical push type buckle is also quite convenient to use. The door of the aforesaid cabinet, the folding shell of a notebook computer or other portable devices, etc.), this kind of push-on buckle has been quite a mature technology.

Please refer to FIG. 1a, FIG. 1b, FIG. 1a, and FIG. 1b are schematic diagrams of a conventional vertical push-fit fastener 1 . Figure 1a shows the state of the buckle 1 not fastened, and Figure 1b shows the state of the buckle 1 fastened. As shown in Figure 1a and Figure 1b, when the buckle 2 of the buckle 1 is pushed down along the direction D1, it will drive the clamping part 3 on the latch body 4 to produce relative movement, so that the clamping part 3 and the buckle 2 are combined At the same time, the pushing member (not shown in the figure) in the latch body 4 also moves along the direction of D1 to buckle itself, so that the buckle bar 2 can be maintained at the position shown in Figure 1b to achieve the purpose of buckling. When you want to release the lock on the buckle 1, you only need to press the buckle bar 2 downward along the direction D1, so that the pushing member in the latch body 4 also moves along the direction D1 to unlock, and at the same time move along the opposite direction of D1 (the upward direction in the figure) ) to push the buckle 2 to return the buckle 2 to the position shown in Figure 1a to complete the unlocking action. The pushing member is a well-known and common technology in the industry, so it will not be described in detail here.

However, since the pushing stroke (D1 direction) of this push-type buckle 1 is the same as the locking/unlocking stroke direction (D1 direction), the size H1 of the buckle 1 in the direction of force must be adequately prepared for its internal components. The action space, while its width W1 is much smaller than its thickness H1. In other words, the existing buckle 1 cannot be further reduced due to the size limitation of its thickness. With the current trend of increasing demand for thinner and smaller devices, if this traditional push-type buckle is to be applied to small devices, it will inevitably occupy more device space and limit the use of small devices. Dimensional design requirements.

Detailed ways

Please refer to FIG. 2 , which is a schematic diagram of the horizontal push-and-pull fastener 10 disclosed in the present invention. The buckle 10 includes a buckle bar 12 , a housing 14 , a latch body 13 and a pushing member 15 (refer to FIG. 3 ). The buckle bar 12 includes a first slope 121, a second slope 122 and a hook 123, which can be installed on the switch door or the detachable shell of the device on which the buckle 10 is set (such as the back of a hand-held electronic device). cover or battery cover) to actuate with the latch body 13. The latch body 13 is disposed in the housing 14 , and the housing 14 can be embedded in the body of the device on which the buckle 10 is disposed. Please refer to FIG. 3 , which is a perspective plan view of components installed on the device body. The latch body 13 is movable in the housing 14, and a push-push component 15 (push-push component) is also arranged in the housing 14 and is interlocked with the latch body 13, and can set the latch body 13 in an unlocking position ( As shown in FIG. 4 ), the latch body 13 is fixed at a locking position (as shown in FIG. 5 ) or pushed by the buckle rod 12 to release the latch body 13 (as shown in FIG. 6 ). Since the action principle and components of the pushing member 15 are well known to those skilled in the art and can be easily completed, they will not be described in detail.

Please refer to Figure 4 to Figure 6. Since the buckle 10 disclosed in the present invention changes the moving direction of the latch body 13 to a direction perpendicular to the force application direction, the thickness occupied by the buckle 10 installed on the device can be effectively reduced, and the size of the device can be effectively reduced. As shown in Figure 4, when the buckle 10 is in the unlock position (such as when the back cover or battery cover of the handheld electronic device is opened), the buckle bar 12 is outside one end of the opening 131 of the latch body 13, and the latch body 13 is on the outside of the opening 131. Under the action of the pushing member 15, the latch body 13 and the housing 14 have a maximum width W2, and the thickness of the housing 14 (also the thickness required for the buckle 10 to be installed on the device) Then it is H2.

When the buckle 12 is pressed relative to the housing 14 along the D2 direction, the first slope 121 of the buckle 12 will push against the wall 132 on the side of the opening 131 on the latch body 13, so as to drive the latch body 13 to face each other along the D3 direction. The housing 14 moves and retracts into the housing 14, while the buckle 12 continues to move downward relative to the latch body 13 along the D2 direction and is gradually inserted and extended in the opening 131 until as shown in FIG. The pushing member 15 interlocked with 13 will fix the latch body 13 at a locking position. Therefore, when the force applied to the buckle bar 12 in the direction of D2 disappears, the latch body 13 is moved slightly in the direction opposite to D3 by the action of the pushing member 15 and remains in the locking position. At this time, the latch body 13 and the housing The body 14 has a width W3 in a locked state. At the same time, the hook 123 of the buckle bar 12 extends from one end of the opening 131 and protrudes outside the other end of the opening 131. Therefore, the hook 123 is drawn by the opening 131. The wall surface 133 on the side is resisted, so that the buckle bar 12 is buckled with the latch body 13 to achieve the purpose of buckling the buckle 10 .

When the buckle 10 is about to be released, in the buckled state of FIG. 5 , force is applied to the buckle bar 12 along the direction D2 again, and the second slope 122 on the buckle bar 12 will push against the latch body 13 at this time. The wall 132 on one side of the opening 131 of the opening 131 drives the latch body 13 to move relative to the housing 14 along the D3 direction to the end position of the maximum compression stroke (as shown in FIG. 6 ). At this time, the latch body 13 and the housing 14 have a The minimum width is W4, and the movement of the buckle bar 12 will prompt the pushing member 15 linked with the latch body 13 to release the latch body 13 . Therefore, when the force applied to the latch rod 12 along the direction D2 disappears, the latch rod 12 is pushed by the latch body 13 to withdraw from the opening 131 of the latch body 13, and the latch body 13 is pushed in the direction opposite to D3 by the action of the pushing member 15. Move to the outwardly extending position as shown in FIG. 4 to achieve the purpose of unlocking the buckle 10 .

As can be seen from the aforementioned actuation process shown in Figures 4 to 6, the horizontal two-stage push-off buckle 10 moves in the direction D3 in the transverse direction (relative to the direction of application of the buckle's locking and releasing force) due to the latch body 13 Therefore, the width of the buckle 10 in the D3 direction needs to prepare a larger size for the movement of the latch body 13, and the buckle 10 only needs to consider the shell in the longitudinal direction (relative to the direction of applying force for buckle locking and releasing) in the D2 direction. The thickness dimension H2 of 14 (which is much smaller than the width dimension W2, W3 or W4 required by the fastener 10, wherein W2>W3>W4), so the thickness of the fastener 10 can be effectively reduced, making the fastener 10 more usable on thinner devices.

In addition, in this embodiment, the first slope 121 and the second slope 122 on the buckle bar 12 are arranged along the direction D2, so when the buckle bar 12 and the latch body 13 are in different relative positions as shown in Fig. 4 and Fig. 6 When the force is applied in a single direction along the D2 direction, the different slopes arranged along the D2 direction on the buckle bar 12 and the latch body 13 will move, and both of them can push the latch body 13 to move along the D3 direction. In this way, the convenience of the push-to-type buckle is also maintained. In the preferred embodiment of the present invention disclosed above, since the force-bearing movement direction D2 of the buckle bar 12 and the direction D3 in which the latch body 13 moves are perpendicular to each other, the first inclined surface 121 and the second inclined surface on the buckle bar 12 It is preferable that 122 run parallel to each other and form 45 degrees with the direction D2 and the direction D3 respectively. However, the direction of the first slope 121 and the second slope 122 on the buckle bar 12 is not the only embodiment of the present invention, and the buckle bar 12 can also exist in other forms, and the slopes on it do not necessarily need to be parallel to each other or to the direction D2. Or the D3 direction maintains an oblique angle of 45 degrees. Therefore, the direction D2 of the buckle 10 applying force to the buckle 12 and the moving direction D3 of the latch body 13 are different from each other, so that the buckle 10 does not need to consider the direction of movement of the latch body 13. Under the characteristics of its thickness, the actuation mode of the buckle bar 12 and the latch body 13 can be changed arbitrarily and all belong to the scope of the present invention.

The horizontal two-stage push buckle disclosed by the present invention utilizes the buckle rod installed on the switch door or the detachable housing to apply force along a first direction, so that the buckle rod pushes the latch disposed along a second direction body. Wherein the latch body is linked with a pushing member, when the latch body moves along the second direction, and the hook of the buckle extends in the opening and is resisted by the wall surface on one side of the opening, then the pushing member pushes the latch The body is pushed back and fixed at a locking position, and at the same time, the latch body engages with the buckle rod, so that the buckle is set in a locked state. When pressing and pushing the latch lever along the first direction again, the latch lever drives the latch body to move to the maximum compression stroke position along the second direction, and drives the pushing member to release the latch body, and the latch body Push the buckle bar out of engagement with the latch body, so that the buckle is set in an unlocked state. The thickness of the latch body arranged along the second direction is much smaller than the width of its movement stroke, which can effectively reduce the required thickness of the buckle installed on any device, so as to be applied to miniaturized devices.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
