Description

Technical Field

[0001] This utility model belongs to the field of guide rail equipment, and specifically relates to a refrigerator drawer guide rail. Background Technology

[0002] Refrigerator drawer slides are mechanical devices used to support and guide the smooth opening and closing of refrigerator drawers. Currently, some refrigerator drawer slides are designed to generate significant impact when the drawer reaches its limit position. When the drawer is quickly pulled out or pushed in, there is no corresponding structure to slow down the speed, resulting in a hard collision between the drawer and the cabinet or slide components. To solve this problem, the conventional approach is to attach soft materials such as rubber strips to the edges of the cabinet or drawer, hoping to mitigate the impact force through their elasticity. However, these soft materials are prone to aging and hardening during long-term use, under the influence of low temperatures, humid environments, and frequent compression, resulting in a significant decrease in elasticity and a gradual weakening of the cushioning effect. Furthermore, the adhesion of rubber strips and similar materials is limited and they may detach, making it difficult to fundamentally and continuously improve the drawer collision problem and failing to meet users' needs for a quiet and durable user experience. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a refrigerator drawer guide rail to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a refrigerator drawer guide rail, comprising: a guide rail assembly, wherein two sets of guide rail assemblies are provided, the two sets of guide rail assemblies have the same structure and are symmetrically arranged with each other, the guide rail assembly includes a guide rail body and a slide rail body for sliding, the guide rail body and the slide rail body are slidably connected to each other, and a buffer member is respectively installed on the rear end of the guide rail body and the lower surface of the slide rail body, wherein multiple sets of buffer members are provided, and the multiple sets of buffer members have the same structure.

[0005] In a preferred embodiment, an L-shaped baffle is integrally formed on the upper edge of the inner surface of the guide rail body, and a roller is rotatably mounted on the front edge of the inner surface of the guide rail body. The length of the guide rail body matches the length of the slide rail body. In use, the two sets of guide rail assemblies can provide more uniform and balanced support for the drawer, ensuring that the drawer remains stable during pulling out and pushing in, reducing shaking and tilting, and preventing items inside the drawer from tipping over or being damaged due to shaking.

[0006] In a preferred embodiment, a limiting groove is formed on the front edge of the upper surface of the guide rail body, and a limiting plate is integrally formed on the inner wall of the limiting groove downwards. The side of the limiting plate away from the limiting groove abuts against the outer surface of the roller two.

[0007] In a preferred embodiment, a slide rail body is mounted on the inner surface of the guide rail body, a baffle is integrally formed on the upper edge of the inner surface of the slide rail body, a mounting plate is integrally formed on the lower edge of the outer surface of the slide rail body, a mounting hole is provided on the surface of the mounting plate, and a roller is rotatably mounted on the rear edge of the inner surface of the slide rail body.

[0008] In a preferred embodiment, the structure of the second roller matches that of the first roller, and the slide rail body is slidably mounted on the inner surface of the guide rail body via the first roller and the second roller. The buffer includes a buffer plate and a spring damper.

[0009] In a preferred embodiment, two spring dampers are symmetrically installed on the front surface of the buffer plate, and a buffer plate is installed on the rear surface of the slide rail body. The end of the spring damper away from the buffer plate abuts against the outer surface of the roller two. In use, when the drawer is pushed in or pulled out to its limit position, the buffer can effectively absorb the impact force of the drawer, preventing the drawer from directly colliding with the refrigerator cabinet or other components. This can slow down the speed of the drawer at the end of its movement, reduce wear and impact on the guide rail body, slide rail body, and the drawer itself, help extend the service life of these components, and reduce the risk of component damage due to frequent impacts.

[0010] In a preferred embodiment, another set of buffer members is installed in front of the second roller via a baffle, and the buffer members in front of the second roller abut against the outer surface of the first roller.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting guide rail components, two sets of guide rail components are set. The two sets of guide rail components have the same structure and are symmetrically arranged. The guide rail components include a guide rail body and a slide rail body for sliding. The guide rail body and the slide rail body are slidably connected to each other. When in use, the two sets of guide rail components can provide more uniform and balanced support for the drawer, ensuring that the drawer remains stable during the process of pulling out and pushing in, reducing shaking and tilting, and preventing items in the drawer from tipping over or being damaged due to shaking.

[0012] 2. By setting buffers, a buffer is installed at the rear end of the guide rail body and on the lower surface of the slide rail body. Multiple sets of buffers are set, and the multiple sets of buffers have the same structure. When the drawer is pushed in or pulled out to its limit position during use, the buffer can effectively absorb the impact force of the drawer, avoid the drawer from directly colliding with the refrigerator cabinet or other parts, thereby slowing down the speed of the drawer at the end of its movement, reducing wear and impact on the guide rail body, slide rail body and the drawer itself, helping to extend the service life of these parts and reducing the risk of damage to parts due to frequent impacts.

[0023] 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 some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figures 1 to 5As the first embodiment of this utility model: a refrigerator drawer guide rail, including: a guide rail assembly 100, the guide rail assembly 100 is provided in two sets, the two sets of guide rail assemblies 100 have the same structure and are symmetrically arranged with each other, the guide rail assembly 100 includes a guide rail body 200 and a slide rail body 300 for sliding, the guide rail body 200 and the slide rail body 300 are slidably connected to each other, a buffer member is respectively installed on the rear end of the guide rail body 200 and the lower surface of the slide rail body 300, and multiple sets of buffer members are provided, the multiple sets of buffer members have the same structure;

[0025] The inner surface of the guide rail body 200 has an L-shaped baffle 220 integrally formed on the upper edge, and a roller 210 is rotatably mounted on the front edge of the inner surface of the guide rail body 200. The length of the guide rail body 200 matches the length of the slide rail body 300.

[0026] A limiting groove 201 is provided on the front edge of the upper surface of the guide rail body 200. A limiting plate 202 is integrally formed on the inner wall of the limiting groove 201 facing downward. The side of the limiting plate 202 away from the limiting groove 201 abuts against the outer surface of the roller 320.

[0027] A slide rail body 300 is mounted on the inner surface of the guide rail body 200. A baffle 2 is integrally formed on the upper edge of the inner surface of the slide rail body 300. A mounting plate 310 is integrally formed on the lower edge of the outer surface of the slide rail body 300. Mounting holes are provided on the surface of the mounting plate 310. A roller 320 is rotatably mounted on the rear edge of the inner surface of the slide rail body 300.

[0028] In use, the user first installs the two sets of guide rail assemblies 100 inside the refrigerator, ensuring symmetrical installation. When installing the guide rail assemblies 100, the guide rail body 200 inside each assembly is installed on the inner wall of the refrigerator, with the slide rail body 300 slidably mounted on the side of the guide rail body 200 furthest from the refrigerator. When installing the drawer, it is simply mounted on the upper surface of the mounting plate 310 on the inner surface of the slide rail body 300. When the drawer is pulled, it moves the slide rail body 300 along the guide rail body 200. This movement causes the rollers 210 and 320 between the slide rail body 300 and the guide rail body 200 to rotate. As the slide rail body 300 moves, the rollers 210 and 320 rotate. Both will rotate, causing the slide rail body 300 to move on the inner surface of the guide rail body 200. At the same time, when the slide rail body 300 moves back and forth, because the front side of the inner surface of the guide rail body 200 is provided with roller 210, and the rear side of the upper surface of the guide rail body 200 is provided with a limiting plate 202 and a limiting groove 201, when roller 320 contacts the limiting plate 202 inside the limiting groove 201, it will be blocked, thereby preventing roller 320 from continuing to move backward. When the slide rail body 300 moves through roller 320, it will not deviate from the guide rail body 200, thus achieving stable sliding. During use, the two sets of guide rail assemblies 100 can provide more even and balanced support for the drawer, ensuring that the drawer remains stable during the pulling out and pushing in, reducing shaking and tilting, and preventing items inside the drawer from tipping over or being damaged due to shaking.

[0029] Please see Figures 1 to 5 As a second embodiment of the present invention: based on the description in the above embodiments, the structure of roller 2 320 is further matched with the structure of roller 1 210. The slide rail body 300 is slidably mounted on the inner surface of the guide rail body 200 through roller 1 210 and roller 2 320. The buffer includes a buffer plate 400 and a spring damper 410.

[0030] Two spring dampers 410 are symmetrically installed on the front surface of the buffer plate 400, and the buffer plate 400 is installed on the rear surface of the slide rail body 300. The end of the spring damper 410 away from the buffer plate 400 abuts against the outer surface of the roller 320.

[0031] Another set of buffer components is installed in front of roller 2 320 via a baffle, and the buffer component in front of roller 2 320 abuts against the outer surface of roller 1 210.

[0032] In use, when the slide rail body 300 slides to the rearmost and frontmost ends through the operation steps of the first embodiment, when the slide rail body 300 slides to the rearmost end, it will stop sliding due to the obstruction of the limiting plate 202. However, at this time, the roller 320 on the inner surface of the slide rail body 300 will make hard contact with the limiting plate 202, thereby causing an impact and achieving the stopping effect. At this time, a spring damper 410 is installed on the rear surface of the guide rail body 200 through the buffer plate 400, and one end of the spring damper 410 is further away from the limiting plate 202. This ensures that the roller 320 contacts the spring damper 410 first before contacting the limiting plate 202. After the roller 320 impacts and contacts the spring damper 410, the kinetic potential energy of the slide rail body 300 will be released by the spring damper 410. The spring damper 410 is an existing technology and is a damper; its specific structure and working principle will not be described in detail here. Similarly, when the slide rail body 300 moves to its foremost position, another set of buffer components installed inside the slide rail body 300 will contact the roller 210, thus achieving a buffering effect in the same way. Since the buffer components can effectively absorb the impact force of the drawer when it is pushed in or pulled out to its limit position, it can prevent the drawer from directly colliding with the refrigerator cabinet or other parts, thereby slowing down the speed of the drawer at the end of its movement, reducing wear and impact on the guide rail body 200, the slide rail body 300, and the drawer itself, helping to extend the service life of these components and reducing the risk of component damage due to frequent impacts.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
