Anti-derailing hardware slide rail safety limiting structure

Abstract

This utility model discloses a safety limiting structure for anti-derailment hardware slide rails, including a hardware slide rail body. A limiting groove is formed inside the hardware slide rail body, and a limiting block is slidably connected inside the limiting groove. A connecting sliding plate is fixedly installed on the top of the limiting block, and a circular ball is fixedly installed on one side of the connecting sliding plate. Adjusting blocks are symmetrically and movably connected to the outer end of the circular ball, and arc-shaped grooves are formed on the inner sides of both adjusting blocks. This anti-derailment hardware slide rail safety limiting structure, by setting the limiting groove, limiting block, circular ball, adjusting block, and arc-shaped groove, allows the limiting block to slide freely within the limiting groove. By moving the limiting block, the connected circular ball can be adjusted, allowing the circular ball to embed into the arc-shaped groove, thereby achieving the self-locking function of the hardware slide rail. When the slide rail is fully closed, the system automatically locks, ensuring that items will not fall during movement, thus enhancing the safety and reliability of the hardware slide rail's limiting function.

Description

Technical Field

[0001] This utility model relates to the field of hardware slide rail technology, specifically to a safety limiting structure for anti-derailment hardware slide rails. Background Technology

[0002] High-quality anti-derailment drawer slides have high load-bearing capacity and a long service life. By reducing friction and wear, they can effectively extend the lifespan of furniture and reduce the need to replace furniture due to drawer slide damage. Drawer slides play a very important role in sliding equipment, ensuring the smooth operation of the equipment.

[0003] Chinese patent CN216454125U proposes a structure to limit the movement of a slide rail bead holder. Addressing the problem of poor limiting effect of existing slide rail bead holders, leading to easy slippage and detachment, thus affecting usability, the following solution is proposed: It includes a slide rail and a bead holder body. The bead holder body is slidably installed within the slide rail. Multiple semi-circular grooves are formed at the bottom of the bead holder body, each containing a movably connected ball bearing. The ball bearing rolls against the inner wall of the bottom of the slide rail. Limiting grooves are formed on both sides of the bead holder body. Transverse grooves are formed on the inner walls of both sides of the slide rail. Limiting plates are slidably installed in two of the transverse grooves. The two limiting plates are slidably installed in their respective limiting grooves. A threaded drive drives the limiting plates to engage with the limiting grooves, limiting the movement of the bead holder within the slide rail and preventing slippage. A locking rod further restricts the movement of the limiting plates, improving stability.

[0004] While the above solution can achieve the limiting function of the metal slide rail, its design is not conducive to realizing the self-locking mechanism. This may cause items to fall during movement, thereby affecting the storage effect of the items and reducing the practical value of the anti-derailment metal slide rail safety limiting structure.

[0024] Please see Figures 1-6 The present invention provides a technical solution: a safety limiting structure for anti-derailment hardware slide rail, including a hardware slide rail body 1, a limiting groove 2 is opened in the middle of the hardware slide rail body 1, so that the whole body is U-shaped, a limiting block 3 is slidably connected inside the limiting groove 2, and a connecting sliding plate 4 is fixedly installed on the top of the limiting block 3.

[0025] A circular ball 5 is fixedly installed on one side of the connecting sliding plate 4. Two adjusting blocks 6 are located outside the circular ball 5 and are movable relative to each other inside the metal slide rail body 1. Both adjusting blocks 6 have arc-shaped grooves 7 on their inner sides, which are adapted to the outer surface of the circular ball 5. A limiting block 3 can slide within the limiting groove 2. By moving the limiting block 3, the connected circular ball 5 can be adjusted, allowing the circular ball 5 to embed into the arc-shaped groove 7, thus achieving the self-locking function of the metal slide rail and enhancing its safety and the reliability of its limiting action.

[0026] The hardware slide rail body 1 has an adjustment component 8 inside, which is fixedly connected to the adjustment block 6 and can drive the two adjustment blocks to move relative to each other. The top of the hardware slide rail body 1 is symmetrically provided with a disassembly component 9, which is connected to a maintenance plate 10. The maintenance plate 10 is located at one end of the hardware slide rail body 1 and is used to open or close the interior of the hardware slide rail body 1.

[0027] The adjustment assembly 8 includes an adjustment groove 81, which is located inside the hardware slide rail body 1. A maintenance plate 10 is positioned at the groove opening. Inside the adjustment groove 81 are two adjustable plates 82 that can move relative to each other. One end of each adjustable plate 82 extends through the maintenance plate 10, which has a slotted hole for lateral movement. The other end of each plate is fixedly fitted with a sliding block 83. Each sliding block 83 is slidably connected to a connecting rod 84, which is fixedly connected to the inner wall of the hardware slide rail body 1. A spring 85 is fitted around the outside of the connecting rod 84, with both ends of the spring 85 fixedly connected to the sliding block 83 and the inner wall of the hardware slide rail body 1, respectively.

[0028] The adjusting component 8 can adjust the distance between the two adjusting blocks 6, thereby facilitating the removal of the round ball 5 from inside the arc groove 7, unlocking the self-locking mechanism of the metal slide rail, and making the use of the anti-derailment metal slide rail more convenient.

[0029] The disassembly assembly 9 includes mounting blocks 91. Two mounting blocks 91 are symmetrically fixedly installed at the top of both ends of the hardware slide rail body 1. Rotating rods 92 are rotatably connected inside each of the two mounting blocks 91. Torsion springs 93 are fixedly installed at the outer ends of the rotating rods 92. One end of the torsion springs 93 is fixedly connected to the inner wall of the mounting blocks 91. A pressing plate 94 is fixedly installed at one end of the rotating rods 92.

[0031] Working principle: The operator manually pulls the pressing plate 94, placing the repair plate 10 at one end of the hardware slide rail body 1. Then, the operator releases the pull, and the rotating rod 92 rebounds using the elasticity of the torsion spring 93. The rotating rod 92 drives the pressing plate 94 to rebound, adjusting the pressing plate 94 to one side of the repair plate 10. The pressing plate 94 is then fixed using the iron plate 95 and the magnetic suction piece 96. With the hardware slide rail body 1 in the fully closed state, the connecting sliding plate 4 drives the limiting block 3 to slide in an arc shape inside the limiting groove 2. The limiting block 3 drives the circular... The ball 5 is adjusted and locked between the two adjusting blocks 6, fixing the ball 5 inside the arc groove 7, thereby locking the metal slide rail. When the metal slide rail needs to be opened, the adjusting plate 82 is manually moved. The two adjusting plates 82 drive the sliding block 83 to adjust outward, and the sliding block 83 drives the adjusting block 6 to adjust, separating the two adjusting blocks 6, thereby opening the metal slide rail. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
