Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and in particular to a side-locking slide rail. Background Technology

[0002] Telescopic slides, as core components enabling linear extension in modern furniture, industrial equipment, and precision instruments, directly determine the user experience through the comfort of their locking mechanism. However, existing telescopic slides, in an effort to save costs, omit the locking mechanism, relying solely on the track's extension limit structure to restrict the slide's travel. This not only degrades the user experience by making the slide feel less comfortable, but also makes the limiting structure prone to damage over prolonged use. Such damage necessitates replacing the entire slide system, thus shortening the slide's lifespan. Therefore, a more durable telescopic locking slide is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a side-locking slide rail to solve the problem of insufficient durability of existing telescopic slide rails.

[0004] The present invention provides the following technical solution: a side-locking slide rail, comprising a fixed track, a movable track, a ball bearing mechanism, and a locking mechanism. The ball bearing mechanism includes a ball bearing bracket and a plurality of balls movably arranged along the length direction of the ball bearing bracket. The ball bearing mechanism is movably disposed between the fixed track and the movable track, allowing the movable track to reciprocate along the length direction of the fixed track. The locking mechanism includes a support, an elastic plate, a pressing lock, and a latch disposed between the fixed track and the movable track. The two ends of the elastic plate are respectively fixed to the support and the pressing lock, allowing the pressing lock to elastically swing closer to or away from the latch. The pressing lock has a recessed slot on the side near the latch. When the movable track extends or retracts relative to the fixed track, the latch approaches and presses the pressing lock until the latch engages with the slot to lock the movement of the movable track.

[0005] As described above, in a side-locking slide rail, the pressing locking member has arched pressing parts on both sides of the latch, so that the side of the pressing locking member is arranged in a "B" shape. When the latch approaches the pressing locking member, the latch first presses against the arched pressing parts and then engages with the latch.

[0006] As described above, in a side-locking slide rail, the side of the latch is triangularly shaped.

[0007] As described above, in a side-locking slide rail, the support is detachably fixed to the movable track, the latch is provided on the fixed track, and the latch is provided at both the beginning and end of the fixed track.

[0008] As described above, in a side-locking slide rail, the support is fixed to one side of the movable rail by screws.

[0009] As described above, in a side-locking slide rail, the support includes a long connecting plate and a short connecting plate. The long connecting plate is parallel to the side of the movable track facing away from the fixed track. The short connecting plate is perpendicularly connected to the long connecting plate, and the elastic plate is parallel to the short connecting plate.

[0010] In the side-locking slide rail described above, the distance between the elastic plate and the short connecting plate is adjustable to adjust the pressing force between the pressing locking member and the latch.

[0011] As described above, in a side-locking slide rail, the longitudinal section of the ball bearing bracket is "I" shaped, and the longitudinal sections of the fixed track and the movable track are both "U" shaped. The fixed track and the movable track respectively surround the two sides of the ball bearing bracket, and multiple balls are sandwiched between the fixed track and the ball bearing bracket, and between the movable track and the ball bearing bracket.

[0012] As described above, in a side-locking slide rail, the ball bearing bracket has a limiting block at both its first and last ends. The limiting blocks are respectively located on both sides of the ball bearing bracket. When the fixed track and the movable track are stretched, the ends that are close to each other are provided with a stretching limiting flange, and the ends that are stretched away from each other are provided with a contraction limiting flange.

[0013] In the side-locking slide rail described above, the fixed rail, the movable rail, and the ball bearing bracket all have rounded corners at the ends of their profiles.

[0014] Compared with the prior art, the present invention has the following advantages: This utility model discloses a side-locking slide rail, which employs a fixed track, a movable track, and a ball bearing mechanism to achieve a telescopic slide rail structure. A locking mechanism is then installed between the fixed track and the movable track to flexibly lock the movable track during movement. The locking mechanism includes a support, a spring plate, a pressure locking element, and a latch. The spring plate connecting the support and the pressure locking element provides an elastic locking effect on the latch. When the movable track extends or retracts relative to the fixed track via the ball bearing mechanism, the latch will engage. As the latch moves, it first exerts a certain squeezing force on the locking element when it approaches the locking member. At this time, the locking member will swing and move aside under the elastic force of the spring plate. When the latch continues to move and reaches the locking part of the locking member, the locking member will rebound under the elastic force of the spring plate to achieve flexible and flexible locking of the latch. The locking mechanism not only effectively protects the limiting structure of the slide rail, but also improves the user experience of the slide rail product and allows for flexible setting of the locking stroke of the slide rail, greatly improving the durability of the slide rail.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to the appendix Figure 1 To be continued Figure 5 This embodiment provides a side-locking slide rail, including a fixed track 1, a movable track 2, a ball bearing mechanism 3, and a locking mechanism 4. The ball bearing mechanism 3 includes a ball bearing bracket 31 and a plurality of balls 32 movably arranged along the length direction of the ball bearing bracket 31. The ball bearing mechanism 3 is movably arranged between the fixed track 1 and the movable track 2, so that the movable track 2 can move back and forth along the length direction of the fixed track 1. The locking mechanism 4 includes a support 41, an elastic plate 42, a pressing lock 43, and a latch 44 disposed between the fixed track 1 and the movable track 2. The two ends of the elastic plate 42 are respectively fixed to the support 41 and the pressing lock 43, so that the pressing lock 43 can elastically swing closer to or away from the latch 44. The side of the pressing lock 43 near the latch 44 has a recessed slot 431. When the movable track 2 extends or retracts relative to the fixed track 1, the latch 44 approaches and presses the pressing lock 43 until the latch 44 engages with the slot 431 to lock the movement of the movable track 2. This embodiment of the side-locking slide rail uses a fixed track 1, a movable track 2, and a ball bearing mechanism 3 to achieve a telescopic slide rail structure. A locking mechanism 4 is then provided between the fixed track 1 and the movable track 2 to flexibly lock the movable track during movement. The locking mechanism 4 includes a support 41, a spring plate 42, a pressing lock 43, and a latch 44. The spring plate 42, connected between the support 41 and the pressing lock 43, provides an elastic locking effect between the pressing lock 43 and the latch 44. When the movable track 2 extends or retracts relative to the fixed track 1 via the ball bearing mechanism 3, the latch 44... 4 will follow the movement. When the latch 44 approaches the pressing lock 43, it will first exert a certain squeezing force on the pressing lock 43. At this time, the pressing lock 43 will swing and move under the elastic force of the elastic plate 42. When the latch 44 continues to move and directly reaches the latch 431 of the pressing lock 43, the pressing lock 43 will rebound under the elastic force of the elastic plate 42 to achieve flexible locking of the latch 44. The setting of the locking mechanism 4 can not only effectively protect the limiting structure of the slide rail, but also improve the user feel of the slide rail product, and can flexibly set the locking stroke of the slide rail, greatly improving the durability of the slide rail.

[0023] The locking member 43 has arched pressing parts 432 on both sides of the latch portion 431, making the side of the locking member 43 "B" shaped. When the latch 44 approaches the locking member 43, the latch 44 first presses against the arched pressing parts 432 and then engages with the latch portion 431. This structure allows the latch 44 to move towards the locking member 43 from either of the two moving directions along the moving track, triggering the locking member 43 to swing and move, thereby enabling the locking member 43 to subsequently lock the latch 44.

[0024] Preferably, the side of the latch 44 is triangular, which makes the process of the latch 44 pressing against the locking member 43 and engaging more smoothly.

[0025] The support 41 is detachably fixed to the movable track 2, and the latch 44 is provided on the fixed track 1. The first and second ends of the fixed track 1 are both provided with latches 44, so that the locking mechanism 4 has the locking effect on the movable track 2 in both the extended and retracted states.

[0026] Preferably, the support 41 is fixed to one side of the movable track 2 by screws, which facilitates the disassembly and assembly of the support 41 and thus facilitates the maintenance of the locking mechanism 4.

[0027] Preferably, the support 41 includes a long connecting plate 411 and a short connecting plate 412. The long connecting plate 411 is parallel to the side of the movable track 2 facing away from the fixed track 1. The short connecting plate 412 is perpendicularly connected to the long connecting plate 411, and the elastic plate 42 is parallel to the short connecting plate 412.

[0028] Preferably, the distance between the elastic plate 42 and the short connecting plate 412 is adjustable to adjust the squeezing force between the pressing locking member 43 and the latch 44, that is, the locking force of the pressing locking member 43 on the latch 44 can be flexibly adjusted.

[0029] Preferably, the longitudinal section of the ball bearing support 31 is "I" shaped, and the longitudinal sections of the fixed track 1 and the movable track 2 are both "C" shaped. The fixed track 1 and the movable track 2 surround the two sides of the ball bearing support 31 respectively, and multiple balls 32 are sandwiched between the fixed track 1 and the ball bearing support 31 and between the movable track 2 and the ball bearing support 31.

[0030] Preferably, the ball bearing support 31 has limiting blocks 311 at both its first and last ends, with the limiting blocks 311 located on both sides of the ball bearing support 31. When the fixed track 1 and the movable track 2 are stretched, the ends that are close to each other are provided with stretching limiting flanges 21, and the ends that are far apart when stretched are provided with contraction limiting flanges 22. The cooperation between the limiting blocks 311 and the stretching limiting flanges 21 can assist in limiting the stretching limit stroke of the movable track 2, and the cooperation between the limiting blocks 311 and the contraction limiting flanges 22 can assist in limiting the contraction limit stroke of the movable track 2.

[0031] Preferably, the ends of the profiles of the fixed track 1, the movable track 2 and the ball bearing bracket 31 are all rounded, which improves the feel of the lifting slide rail during installation and prevents cuts to the hands.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
