Description

Technical Field

[0001] The utility model relates to the technical field of silent sliders, in particular to a silent slider capable of preventing steel balls from colliding. Background Art

[0002] Silent guide rails are a special type of guide rail with functions such as shock absorption, noise reduction, and anti-slip. The main function of silent guide rails is noise reduction. By reducing the friction and collision between sliding parts and guide rails, sliding is made smoother, thereby reducing noise generation. Silent guide rails achieve the effect of noise reduction by adding some special materials to the guide rails or adopting special design structures to reduce the friction and collision between doors, drawers or sliding parts and guide rails. For example, in some designs, the slider can slide along the outside of the guide rail, and the balls roll in the raceway. The collision between the balls is prevented by structures such as ducts and separators. At the same time, the retaining frame is used to absorb the noise generated by the rolling of the balls, thereby reducing the spread of internal noise.

[0003] Chinese patent publication CN216382240U discloses a silent slider with a nylon chain and a guide tube. The silent slider includes a guide rail assembly, a lubrication assembly, and a cleaning assembly. The guide rail assembly is located at the top of the slider assembly and slides therebetween. Two cleaning assemblies are located at both ends of the slider assembly and are engaged with the slider assembly. The lubrication assembly is located on one side of the cleaning assembly and is engaged with the slider assembly. The utility model improves the smoothness of the slider during sliding by providing a nylon silent tube, a guide rail dust cover strip, and a dust sheet on the guide rail assembly. The cleaning assembly also cleans the slider assembly, thereby achieving a certain degree of silence. While increasing the dustproof effect, it also reduces the damage caused by the slider's return mechanism being damaged by impact. However, the silent slider with a nylon chain and a guide tube uses a nylon link to limit the steel ball. If the nylon chain breaks, the normal operation of the slider is affected and the silent effect is lost.

[0004] Existing silent sliders mostly use chains or spacers to separate the steel balls. If the chains are broken or the spacers are misplaced, the sliding smoothness of the silent slider will be affected.

[0005] In order to solve the above-mentioned deficiencies in the prior art, it is a problem worth studying to provide a silent slider that prevents steel balls from colliding. Utility Model Content

[0006] The purpose of the present utility model is to overcome the shortcomings of existing silent sliders that most of them use chains or spacers to separate the steel balls, and the sliding smoothness of the silent slider will be affected if the chain breaks or the spacers are misplaced. A silent slider is provided that prevents the collision of steel balls, thereby achieving the technical effect of stable and efficient silent sliding of the slider.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] A silent slider for preventing steel ball collisions, comprising a guide rail, a slider being slidably connected to the guide rail, and a noise-reducing steel ball module being provided at the junction of the guide rail and the slider;

[0009] The noise reduction steel ball module includes a guide groove provided on the guide rail and the slide block, and a steel ball arranged in the guide groove.

[0010] The noise reduction steel ball module also includes nylon balls. The diameter of the nylon balls is equal to that of the steel balls. The steel balls and the nylon balls are distributed at intervals inside the guide groove. Nylon balls are arranged between the steel balls of the slider so that the nylon balls can separate all the steel balls. During the sliding of the slider, the steel balls will not collide with each other, thereby reducing the noise generated during the entire sliding process of the slider.

[0011] There are spacers between the steel balls, and the material of the spacers is nylon. Matching grooves are provided on both sides of the spacers. The shape of the matching grooves is adapted to the side shape of the steel balls. The spacers made of nylon material are arranged between the steel balls. The spacers can block and buffer the steel balls, avoid the noise caused by the steel balls colliding with each other during the sliding of the slider, and realize silent sliding of the slider.

[0012] The top and bottom of the guide groove are fixedly connected to the limiting blocks, and the inner shape of the limiting blocks is adapted to the outer shape of the steel balls. By arranging the limiting blocks on the guide groove, the position of the steel balls during rolling is limited, thereby avoiding mutual collisions caused by position offset when the steel balls roll in the guide groove, reducing the noise generated by collisions between the steel balls, and achieving silent sliding.

[0013] The steel balls and nylon balls are distributed at intervals in the guide groove, and spacers are provided at the gaps between the steel balls and the nylon balls. Spacers are provided in the guide groove where the steel balls and the nylon balls are arranged at intervals to further separate the steel balls and the nylon balls, and the spacers can further limit the steel balls and the nylon balls, thereby improving the overall stability and silent effect of the sliding of the slider.

[0014] The top and bottom of the guide groove are provided with limiting blocks, the steel balls are arranged in the matching grooves between the limiting blocks, and a spacer is arranged between the steel balls.

[0015] Positive beneficial effects: 1. The anti-collision steel ball silent sliding block can separate the steel balls, so that the steel balls do not collide with each other during the sliding process of the sliding block, thereby reducing the noise generated during the sliding process of the sliding block. During the operation of the sliding block, the nylon ball has a certain elasticity, which can support the guide rail and the sliding block to some extent, reduce the friction noise between the sliding block and the guide rail during the sliding process, and achieve the effect of shock absorption and noise reduction, so that the sliding block slides on the guide rail more smoothly.

[0016] 2. The anti-collision steel ball silent sliding block is provided with a nylon spacer between the steel balls, which can block and buffer the steel balls, avoid the noise generated by the mutual collision of the steel balls during the sliding process of the sliding block, and realize the silent sliding of the sliding block.

[0017] 3. The anti-collision steel ball silent sliding block is provided with a limiting block on the guide groove to limit the position of the steel ball during rolling, so as to avoid the mutual collision caused by the position deviation of the steel ball during rolling in the guide groove, reduce the noise generated by the collision between the steel balls, and realize the silent sliding.

[0025] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example 1

[0026] like Figures 1 to 6 As shown, a silent slider for preventing steel ball collisions comprises a guide rail 1, a slider 2 is slidably connected to the guide rail 1, and a noise-reducing steel ball module is provided at the connection portion between the guide rail 1 and the slider 2;

[0027] The noise reduction steel ball module includes a guide groove 3 formed on a guide rail 1 and a slider 2 , and a steel ball 4 disposed in the guide groove 3 .

[0028] like Figures 1 to 3 As shown, the noise reduction steel ball module further includes nylon balls 5. The diameter of the nylon balls 5 is equal to that of the steel balls 4. The steel balls 4 and the nylon balls 5 are spaced apart inside the guide groove 3. By arranging the nylon balls 5 between the steel balls 4 of the slider, the nylon balls 5 can completely separate the steel balls 4. During the sliding process of the slider 2, the steel balls 4 will not collide with each other, thereby reducing the noise generated during the entire sliding process of the slider;

[0029] During the operation of the slider, the nylon ball has a certain elasticity, which can provide a certain support for the guide rail 1 and the slider 2, reduce the friction noise between the slider 2 and the guide rail 1 during the sliding process, play a shock-absorbing and noise-reducing effect, and make the slider 2 slide on the guide rail 1 more smoothly;

[0030] Compared with the solution of using nylon chain to limit all steel balls to reduce the running noise of the slider, there is a risk of nylon chain breaking during use. If the nylon chain breaks, the sliding of the slider loses its noise reduction advantage, and the broken nylon chain will also interfere with the smooth sliding of the slider. The nylon ball 5 is arranged between the steel balls 4, which can achieve excellent noise reduction effect and avoid the situation where the noise reduction effect is affected by breakage during the noise reduction operation. When a single nylon ball is damaged or falls off, it can be replaced with a new nylon ball. It is more convenient to maintain than the nylon chain and is not prone to damage and malfunction. Example 2

[0031] like Figure 4As shown, spacers 6 are provided between the steel balls 4. The spacers 6 are made of nylon material. Matching grooves are provided on both sides of the spacers 6. The shape of the matching grooves matches the side shape of the steel balls 4. By providing spacers 6 made of nylon material between the steel balls 4, the spacers 6 can have a blocking and buffering effect on the steel balls 4, thereby avoiding the noise generated by the steel balls 4 colliding with each other during the sliding process of the slider 2, thereby achieving silent sliding of the slider;

[0032] The matching grooves on both sides of the spacer 6 can play a certain role in matching and limiting the steel ball 4, making the matching between the spacer 6 and the steel ball 4 more stable, and making the rolling of the steel ball 4 in the guide groove 3 more stable. The nylon spacer 6 buffers part of the vibration of the steel ball 4 during the rolling process, making the rolling of the steel ball 4 more stable and improving the stable and silent sliding of the slider 2.

[0033] Furthermore, the friction coefficient between the gasket 6 and the steel ball 4 is less than 0.5, and lubricating oil can be regularly added between the gasket 6 and the steel ball 4 to further reduce the friction between the gasket 6 and the steel ball 4, so that the steel ball 4 can be subjected to as little friction resistance as possible during the rolling process, avoiding the friction of the gasket 6 hindering the rolling of the steel ball 4 and causing the slider to slide with difficulty. Example 3

[0034] like Figure 5 As shown, the top and bottom of the guide groove 3 are fixedly connected to the limit blocks 7. The inner shape of the limit blocks 7 is adapted to the outer shape of the steel balls 4. By arranging the limit blocks 7 on the guide groove 3, the position of the steel balls 4 when rolling is limited, thereby avoiding mutual collision caused by position deviation when the steel balls 4 roll in the guide groove 3, reducing the noise generated by the collision between the steel balls 4, and achieving silent sliding.

[0035] The friction coefficient between the limit block 7 and the steel ball 4 is limited, and lubricating oil is added to the groove of the limit block 7 to reduce the friction between the steel ball 4 and the limit block 7, so that the limit block 7 can stably limit the steel ball 4 while reducing the interference of friction on the rolling of the steel ball 4. Example 4

[0036] like Figure 4 As shown, the steel balls 4 and the nylon balls 5 are spaced apart in the guide groove 3, and spacers 6 are provided at the gaps between the steel balls 4 and the nylon balls 5. By providing spacers 6 in the guide groove 3 where the steel balls 4 and the nylon balls 5 are spaced apart, the steel balls 4 and the nylon balls 5 are further divided, and the spacers 6 can further limit the steel balls 4 and the nylon balls 5, thereby improving the overall stability and quietness of the sliding of the slider. Example 5

[0037] like Figure 6As shown, limit blocks 7 are provided at the top and bottom of the guide groove 3, and the steel balls 4 are provided in the matching grooves between the limit blocks 7. Spacers 6 are provided between the steel balls 4. By arranging limit blocks 7 and spacers 6 in the guide groove 3 to limit the steel balls 4, the cooperation of the two can make the rolling of the steel balls 4 more stable, reduce the noise generated by the vibration of the steel balls 4 during the movement process, and the spacers 6 can block the steel balls 4 to reduce the noise generated by mutual collisions. The spacers 6 can also cushion the vibration of the steel balls 4 themselves to reduce noise.
