A drawer slide device with press-rebound and buffer functions.

Abstract

This invention belongs to the technical field of drawer slide devices, and is a drawer slide device with press-rebound and buffer functions. It includes a drawer slide, a fixed rail, and a sliding rail. The sliding rail is fitted onto the fixed rail and can move along the fixed rail. Both the fixed rail and the sliding rail are provided with multiple push pins. A spring-back mechanism is located on the fixed rail. The spring-back mechanism includes a spring-back device, a spring-back lever, and a hook. One side of the hook has a press-lock groove, which has at least one ramp and a locking point. A buffer mechanism is located on the sliding rail. The buffer mechanism includes a buffer and a steering rail. The buffer is connected to a switch claw, which has a groove. The spring-back lever causes the hook to engage with the locking point of the press-lock groove, or to disengage from the press-lock groove via the at least one ramp, allowing the spring-back device to more accurately push against the drawer slide. Because the overall number of components is small, the cost can be effectively reduced.

Description

Technical Field

[0001] This invention belongs to the technical field of drawer slides, and relates to a drawer slide, and more particularly to a drawer slide device with press-rebound and buffer functions. Background Technology

[0002] For example, CN111629631A discloses a "configuration system including support tabs and retaining devices for drawer bottoms," as in this case... Figure 7 As shown, it includes a driving device, specifically an ejection device, a holding device, and a fixing element. If a buffering function is required, an additional buffer device is needed to achieve the effect of buffering and pressing to eject. Although the buffering and pressing-to-eject effect can be achieved through the buffer device and driving device, the large number of components results in a complex structure, cumbersome assembly, long manufacturing time, and high production costs.

[0003] Therefore, the above-mentioned issues are problems that need to be considered and solved in the design and use of drawer slides. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a drawer slide device with a reasonable structure that overcomes the deficiencies of the prior art and features press-to-rebound and buffer functions.

[0005] The technical solution of this invention is: a drawer slide rail device with press-to-rebound and buffer functions, comprising a fixed rail and a sliding rail. The fixed rail has a track, and the sliding rail is fitted onto the fixed rail and slides along the track. The fixed rail has a spring-loaded mechanism, which includes a mounting base and a spring-loaded device. One end of the spring-loaded device is connected to a spring-loaded lever via a lever connector. The lever connector has a lever rebound post on one side of the spring-loaded lever, and one end of the lever connector has a hook, the other end of which is connected to a press-locking groove. A buffer mechanism is provided on one side of the sliding rail, comprising a steering track and a buffer disposed on the steering track. One end of the buffer has a switch claw, and the other end has a buffer lever. The fixed rail has a centering switch claw lever and a driving switch claw lever, and the sliding rail has a driving press lever lever and an actuating press lever lever.

[0006] A further improvement of the present invention is that: the lever connector is provided with a lever rebound post on one side of the rebound lever, one end of the lever connector is provided with a hook, and the other end of the hook is connected to the pressing point groove.

[0007] A further improvement of the present invention is that the switch claw and the buffer are connected by a switch claw connector, and the switch claw is provided with a groove.

[0008] A further improvement of the present invention is that: a slot for limiting the buffer lever is provided at the rear of the steering track, and a fixed buffer lever pin is provided at one end of the fixed rail.

[0009] A further improvement of the present invention is that: a positioning post is provided in the middle of the rebound lever, and a shaft hole for connecting the positioning post is provided on the lever connector.

[0010] A further improvement of the present invention is that: the pressing and locking groove is provided with an inlet ramp, an outlet ramp, and a locking point corresponding to the hook end of the hook, and the inlet ramp and the outlet ramp are respectively connected to the two sides of the locking point.

[0011] A further improvement of the present invention is that: the mounting base is provided with a mounting groove, and the spring returner, spring return lever and pressing point groove are all arranged in the mounting groove.

[0012] A further improvement of the present invention is that both the rebounder and the buffer are springs.

[0013] The beneficial effects of this invention are: the drawer slide device has a simple structure, is easy to assemble, and has a low production cost, while having a press-back and buffering function. It uses a rebound lever to make the hook lock in the pressing point groove, or to disengage from the pressing point groove via at least one ramp, so that the rebounder can more accurately rebound and push into the drawer slide. Moreover, because the overall number of components is small, the cost can be effectively reduced. If the external force is too large during use, the buffering mechanism can be used to prevent the components from colliding with each other and causing noise or damage, thereby improving its service life.

Detailed Implementation

[0029] To enhance understanding of the present invention, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain the invention and do not limit the scope of protection of the invention.

[0030] This embodiment provides a drawer slide device with press-rebound and buffer functions. Please refer to [link to relevant documentation]. Figure 1 As shown, it includes drawer slide 1, spring-back mechanism 2 and buffer mechanism 3.

[0031] See Figure 2 and Figure 3As shown, the drawer slide 1 refers to a metal device that facilitates the smooth opening and closing of a drawer. The drawer slide 1 includes a fixed rail 11 and a sliding rail 12. The fixed rail 11 is L-shaped, and the sliding rail 12 is U-shaped. A track 13 is provided on the fixed rail 11, and the sliding rail 12 is fitted onto the fixed rail 11 and can move along the track 13 on the fixed rail 11. The fixed rail 11 is provided with a forward opening / closing claw lever 111 and a drive opening / closing claw lever 112. The sliding rail 12 is provided with a drive pressing lever lever 121 and an actuation pressing lever lever 122.

[0032] refer to Figure 2 and Figure 4 As shown, the spring-loaded mechanism 2 is mounted on the fixed rail 11. The spring-loaded mechanism 2 includes a mounting base 20 and a spring-loaded device 21. One end of the spring-loaded device 21 is provided with a spring-loaded lever 22 and a hook 23. A pressing slot 24 is provided on one side of the hook 23. (See reference...) Figure 5 As shown, the pressing point groove 24 is provided with an inlet ramp 241, an outlet ramp 242, and a locking point 243. The two sides of the locking point 243 are respectively connected to the inlet ramp 241 and the outlet ramp 242. The mounting base 20 is provided with a mounting groove 201, and the rebound device 21, the rebound lever 22, and the pressing point groove 24 are all disposed in the mounting groove 201.

[0033] In detail, one end of the spring-loaded spring mechanism 21 is provided with a lever connector 25, and the middle of the spring-loaded lever 22 is provided with a positioning post 221. The lever connector 25 is provided with a shaft hole 251 corresponding to the positioning post 221 for connecting the spring-loaded lever 22. One end of the lever connector 25 is provided with a hook 23, and the lever connector 25 is provided with a lever rebound post 26 on one side of the spring-loaded lever 22. The spring-loaded spring mechanism 21 is a spring. Please refer to [link / reference]. Figure 2 and Figure 6 As shown, the buffer mechanism 3 is located on one side of the sliding rail 12. The buffer mechanism 3 includes a buffer 31 and a steering rail 32. The buffer 31 is connected to a switch claw 33, and the switch claw 33 has a groove 331. The buffer 31 and the switch claw 33 are connected by a switch claw connector 34. The buffer 31 can be a spring. The other end of the buffer 31 is provided with a buffer lever 35. The steering rail 32 is provided with a slot 351 for limiting the buffer lever at the rear. One end of the fixed rail 11 is also provided with a fixed buffer lever post 113.

[0034] The operating principle of this embodiment is as follows: (See below) Figure 5 , Figure 6 and Figure 7 In this embodiment, it is used on the supported object 4, which can be a drawer or a wardrobe (such as...). Figure 14 As shown), the supported object 4 is fixed to one side of the sliding rail 12. The supported object 4 is in a closed state (i.e., the drawer is closed). The spring-loaded mechanism 2's spring-loaded mechanism 2 is in a stretched state and accumulates elastic force. The hook 23 at one end of the lever connector 25 is locked in the locking point 243 of the pressing locking point groove 24. When the supported object 4 is pressed by an external force (i.e., when the drawer is pressed to make it pop out), the supported object 4 will drive the sliding rail 12 to move. As the sliding rail 12 moves, the actuating pressing lever pin 122 pushes the lever rebound pin 26 of the lever connector 25, thereby driving the hook 23 at one end of the lever connector 25 to disengage from the locking point 243 along the exit ramp 242 of the pressing locking point groove 24. Figure 8 As shown, the spring mechanism 21 releases its elastic force, ejecting the supported object 4. Simultaneously, when the supported object 4 is pressed by an external force, please refer to... Figure 12 and Figure 13 As shown, the drive pawl pin 112 of the fixed rail 11 will press inward, causing the switch claw 33 of the buffer mechanism 3 to disengage from the drive pawl pin 112, that is, the drive pawl pin 112 will leave the groove 331 of the switch claw 33. Please refer to Figure 9 and Figure 10 As shown, as the sliding rail 12 moves gradually, the sliding rail 12 drives the pressing lever 121 to touch and swing the return lever 22, thus smoothly opening the drawer. Afterwards, the return lever 22, after swinging, will touch the lever rebound post 26, as... Figure 11 As shown, because the lever rebound post 26 has elasticity, it will spring back the rebound lever 22 to achieve the effect of automatic alignment. At the same time, the alignment opening and closing claw post 111 drives the switch claw 33 to slide forward to the position, and then swings the switch claw 33 inward along the steering track 32 to fix the switch claw 33 to facilitate the opening buffer effect when closing the drawer.

[0035] See Figure 10 and Figure 11 When the drawer is closed, the push-button lever 121 will move the spring lever 22 forward until it locks the hook 23, so that the hook 23 faces the guide ramp 241 of the push-button slot 24. At the same time, the object 4 will move the sliding rail 12. As the sliding rail 12 moves, it will move the buffer lever 35 to the fixed buffer lever 113. The buffer mechanism 3 will continue to move to the rear slot 351, so that the buffer lever 35 is fixed in the rear slot 351. The buffer function is activated by fixing the buffer lever 113. When the switch claw 33 reaches the opening and closing claw lever 112, the switch claw 33 is aligned (the buffer assembly spring) and the switch claw connector 34 (marked in) is activated. Figure 6The buffering action is completed by moving the lever backward. Simultaneously, the activation lever is moved to 122 (marked as follows). Figure 7 It is stuck on the lever rebound post 26.
