Description

Technical Field

[0001] This utility model relates to the field of slide rail related products, specifically a self-closing device for a slide rail component. Background Technology

[0002] Drawer slides are widely used in drawers of various furniture, refrigerators, ovens, and other home appliances to facilitate the opening and closing of drawers. Existing drawer slide mechanisms often include a self-closing mechanism that enables the drawer to close automatically. For example, Chinese utility model patent CN215604261U discloses a two-section miniature automatic closing mechanism, which includes an outer frame and an inner frame that slides within the outer frame. The front end of the inner frame is an arc segment, and a slider housing and slider are fixed to the front end of the outer frame. The slider contacts the inner frame via rollers. While this structure can achieve the automatic closing function of the inner frame, the upper frame of the inner frame must be designed with a smooth section in the main body and an arc segment at the end. This increases the difficulty of manufacturing the inner frame, especially for small-sized drawer slides where the arc segment at the end of the inner frame is even more challenging. Furthermore, the current automatic closing mechanism requires fixing components such as the drawer housing and slider to the front end of the outer frame, making the device complex and multi-component. Utility Model Content

[0003] The purpose of this invention is to provide a self-closing device for a slide rail component to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-closing device for a slide rail component, comprising a fixed track and a movable track. A track groove is provided on one side of the fixed track, and the movable track is movably inserted into the track groove. A strip-shaped groove is provided at the top of the movable track, and a wedge plate is fixedly connected within the strip-shaped groove. A shaft is rotatably connected to the outer wall of one side of the fixed track, and a traction plate is fixedly sleeved on the shaft. A swing plate is fixedly connected to the side wall of one end of the traction plate, and a support plate is fixedly connected to one end of the swing plate. A rotating rod is rotatably connected to one side of the support plate, and a pressure wheel is fixedly sleeved on the rotating rod. A slot is provided on the outer wall of the fixed track, and a sliding rod is fixedly connected within the slot. A connecting block is slidably sleeved on the sliding rod, and the connecting block is fixedly connected to the traction plate. An elastic element is sleeved on the sliding rod, and both ends of the elastic element are fixedly connected to the inner wall of the slot and the traction plate, respectively.

[0005] Preferably, the end of the wedge plate closest to the fixed track has a wide side, and the end of the wedge plate furthest from the fixed track has a narrow side.

[0006] Preferably, the elastic element is a spring.

[0007] Preferably, the slot is an arc-shaped structure.

[0008] Preferably, the inclined surface at the top of the wedge plate is a polished surface.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The self-closing device of this slide rail component is achieved by a movable track slidably inserted into a groove on a fixed track. When the movable track is stretched outward, the pressure on the support plate moves from the narrow side to the wide side of the wedge plate. At the same time, the pressure wheel moves upward, causing the swing plate to swing. Simultaneously, the swing plate causes the traction plate to rotate around the shaft. The other end of the traction plate causes the connecting block to slide on the slide rod, compressing the elastic element. When the movable track is not subjected to external tension, the elastic force of the elastic element causes the traction plate to return to its original position. At the same time, the swing plate drives the pressure wheel to press against the wedge plate. Under the action of the inclined surface of the wedge plate, the movable track is forced to retract into the fixed track, achieving self-closing. This utility model achieves self-closing guidance of the movable track by using the characteristics of the wedge structure, eliminating the need for custom-shaped movable tracks and reducing processing difficulty.

[0018] Please see Figure 1-3 This utility model provides an embodiment of a self-closing device for a slide rail component, comprising a fixed track 1 and a movable track 2. A track groove 3 is provided on one side of the fixed track 1, and the movable track 2 is movably inserted into the track groove 3. A strip groove 4 is provided at the top of the movable track 2, and a wedge plate 5 is fixedly connected within the strip groove 4. A shaft 6 is rotatably connected to the outer wall of one side of the fixed track 1, and a traction plate 7 is fixedly sleeved on the shaft 6. A swing plate 8 is fixedly connected to the side wall of one end of the traction plate 7, and a support plate 9 is fixedly connected to one end of the swing plate 8. A rotating rod 10 is rotatably connected to one side of the support plate 9, and a pressure wheel 11 is fixedly sleeved on the rotating rod 10. A slot 13 is provided on the outer wall of the fixed track 1, and a sliding rod 14 is fixedly connected within the slot 13. A connecting block 15 is slidably sleeved on the sliding rod 14, and the connecting block 15 is fixedly connected to the traction plate 7. Elastic element 12 is fitted on the slide bar 14. The two ends of elastic element 12 are fixedly connected to the inner wall of the slot 13 and the traction plate 7, respectively. Specifically, the movable track 2 is slidably inserted into the track groove 3 on the fixed track 1. When the movable track 2 is stretched outward, the pressure wheel 11 installed on the support plate 9 moves from the narrow side to the wide side of the wedge plate 5. At the same time, the pressure wheel 11 moves upward and drives the swing plate 8 to swing. At the same time, the swing plate 8 causes the traction plate 7 to rotate around the shaft 6. The other end of the traction plate 7 will cause the connecting block 15 to slide on the slide bar 14 and compress the elastic element 12. When the movable track 2 is not subjected to external tension, the elastic force of the elastic element 12 causes the traction plate 7 to return. At the same time, the swing plate 8 will drive the pressure wheel 11 to press against the wedge plate 5. Under the action of the inclined surface of the wedge plate 5, the movable track 2 will be forced to return to the fixed track 1 to achieve self-closure.

[0019] In this embodiment, the end of the wedge plate 5 closest to the fixed track 1 is a wide side, and the end of the wedge plate 5 furthest from the fixed track 1 is a narrow side; the elastic element 12 is a spring with high traction; the slot 13 is an arc-shaped structure that causes the traction plate 7 to swing circumferentially; the top inclined surface of the wedge plate 5 is a polished surface to reduce frictional resistance.

[0020] Working principle: First, the movable track 2 is slidably inserted into the track groove 3 on the fixed track 1. When the movable track 2 is stretched outward, the pressure roller 11 installed on the support plate 9 moves from the narrow side of the wedge plate 5 to the wide side. At the same time, the pressure roller 11 moves upward, causing the swing plate 8 to swing. Simultaneously, the swing plate 8 causes the traction plate 7 to rotate around the shaft 6. The other end of the traction plate 7 causes the connecting block 15 to slide on the slide rod 14 and compress the elastic element 12. When the movable track 2 is not subjected to external tension, the elastic force of the elastic element 12 causes the traction plate 7 to return. At the same time, the swing plate 8 will drive the pressure roller 11 to press against the wedge plate 5. Under the action of the inclined surface of the wedge plate 5, the movable track 2 is forced to retract into the fixed track 1 to achieve self-closure.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
