Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically a slide rail transmission mechanism with anti-detachment function. Background Technology

[0002] Drawer slides are an essential component of drawer assembly. Their structure typically consists of three slide rails: an upper rail, a middle rail, and a lower rail, which slide sequentially together. The upper rail is mounted on the drawer, and the lower rail is mounted on the cabinet. When the drawer is pulled out, the slide rails extend and retract accordingly, allowing the drawer to slide open and close.

[0003] Currently, to improve the smoothness and stability of drawers when opening and closing, a transmission mechanism is added to the drawer slides. This transmission mechanism includes a synchronous transmission component and a ball bearing assembly. The ball bearing assembly consists of an upper ball bearing assembly and a lower ball bearing assembly. The upper ball bearing assembly is slidably connected between the upper and middle rails, while the lower ball bearing assembly is slidably connected between the middle and lower rails. The synchronous transmission component includes an upper rack, a lower rack, and a drive wheel. The upper and lower racks are respectively mounted on the upper and lower rails, and the drive wheel is mounted on the middle rail and engages with the upper and lower racks respectively as the drawer slides open and close.

[0004] However, the slide rail transmission structure described above has the following shortcomings in practical applications:

[0005] 1) Since the upper and lower racks slide on the upper and lower rails respectively, during operation, the upper and lower racks may deviate from their original sliding trajectory due to excessive speed, causing the bead nest assembly to get stuck between the upper and middle rails or between the lower and middle rails, affecting the normal operation of the slide rail.

[0006] 2) Existing synchronous transmission components are integrally molded with bead socket components, resulting in large volume, high precision requirements, and high manufacturing costs. Furthermore, during the opening and closing of the slide rail, the transmission wheel is prone to separating from the upper and lower racks when the synchronous transmission component is under load, affecting the synchronous operation of the slide rail and reducing the quality of the product.

[0007] 3) Existing synchronous transmission components are prone to collision with the upper, middle or lower rails during load operation, generating significant noise and reducing product performance. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a slide rail transmission mechanism with anti-detachment function. It has a simple structure, effectively prevents deviation during operation, improves stability and smoothness, ensures synchronous operation, is reliable and practical, and guarantees the product's performance.

[0009] The purpose of this invention is achieved as follows: A slide rail transmission mechanism with anti-detachment function includes an upper rail, a middle rail, and a lower rail connected in sequence. A combined bead socket component is slidably connected between the middle rail and the upper and lower rails. The combined bead socket component includes an upper bead socket group and a lower bead socket group. A synchronous linkage group for synchronous operation of the upper rail and the middle rail is provided between the upper bead socket group and the lower bead socket group. The synchronous linkage group includes an upper linkage rack, a lower linkage rack, and a synchronous gear. The synchronous gear is rotatably connected to the middle rail and meshes with the upper linkage rack and the lower linkage rack respectively. The upper linkage rack and the lower linkage rack are respectively provided with anti-detachment connectors for preventing deviation and separation. The anti-detachment connectors are directionally connected to the upper rail and the lower rail along with the upper linkage rack and stop in the upper rail or the lower rail when opening and closing.

[0010] Based on the above optimization, the anti-detachment connector includes an anti-offset protrusion, which is respectively placed at the top end of the upper linkage rack and the bottom end of the lower linkage rack, and respectively moves with the upper linkage rack and the lower linkage rack to form a directional friction connection with the inner wall of the upper rail and the lower rail.

[0011] Based on the above optimization, the anti-offset protrusion is integrated on the top of the left and right sides of the upper linkage rack and the bottom of the left and right sides of the lower linkage rack.

[0012] Based on the above optimization, the anti-offset protrusion is set as a bridge-type protrusion.

[0013] Based on the above optimization, the anti-detachment connector further includes an upper buffer stop and a lower buffer stop. The upper buffer stop is respectively located on the left and right sides of the upper linkage rack, and the lower buffer stop is respectively located on the left and right sides of the lower linkage rack. The front end of the middle rail and the rear end of the upper rail are respectively provided with upper stop protrusions that are elastically connected to the corresponding upper buffer stop as they open and close. The rear end of the middle rail and the front end of the lower rail are respectively provided with lower stop protrusions that are elastically connected to the corresponding lower buffer stop as they open and close.

[0014] Based on the above optimization, the upper and lower linkage racks each have raised teeth for meshing with the synchronous gear under load.

[0015] Based on the above optimization, the upper bead nest group and the lower bead nest group are respectively located at the front end and the lower end of the upper linkage rack and the lower linkage rack, and respectively form an L-shaped upper transmission group and an L-shaped lower transmission group with the upper linkage rack and the lower linkage rack.

[0016] The advantages of this utility model are:

[0017] 1) By adding anti-detachment connectors, the upper bead nest group, lower bead nest group, and synchronous linkage group can be directionally slidably connected between the middle rail and the upper rail, and between the middle rail and the lower rail, respectively, effectively preventing deviation during operation, improving stability and smoothness, ensuring reliability and practicality, and guaranteeing the product's performance.

[0018] 2) The upper and lower linkage racks using this structure utilize their increased teeth to prevent the synchronous gears from disengaging from the upper and lower linkage racks under load, ensuring reliability, practicality, synchronous operation, and the quality of the slide rail.

[0019] 3) Under the action of the upper and lower buffer stops, the slide rail has a buffering and stopping effect, which avoids collisions during load operation, reduces noise generation, has a good stopping effect, and improves the quality of product use. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] According to the appendix Figures 1 to 5As shown, the slide rail transmission mechanism with anti-detachment function of this utility model includes an upper rail 1, a middle rail 2, and a lower rail 3 connected in sequence. A combined beaded assembly is slidably connected between the middle rail 2 and the upper rail 1 and lower rail 3. The combined beaded assembly includes an upper beaded assembly 4 and a lower beaded assembly 5. A synchronous linkage group for synchronous operation of the upper rail 1 and the middle rail 2 is provided between the upper beaded assembly 4 and the lower beaded assembly 5. The synchronous linkage group includes an upper linkage rack 6, a lower linkage rack 7, and a synchronous gear 8. The synchronous gear 8 is rotatably connected to the middle rail 2 and meshes with the upper linkage rack 6 and the lower linkage rack 7 respectively. The upper linkage rack 6 and the lower linkage rack 7 are respectively provided with anti-detachment connectors to prevent deviation and separation. The anti-detachment connectors are oriented with the upper linkage rack 6 and the lower linkage rack 7 and stop within the upper rail 1 or the lower rail 3 when opening and closing.

[0027] By adding anti-detachment connectors, the upper bead nest group 4, the lower bead nest group 5, and the synchronous linkage group can be directionally slidably connected between the middle rail 2 and the upper rail 1, and between the middle rail 2 and the lower rail 3, respectively. This effectively prevents deviation during operation, improves stability and smoothness, ensures reliability and practicality, and guarantees the product's performance.

[0028] Reference Figures 1 to 5 As shown, further detailed, the anti-detachment connector includes an anti-displacement protrusion 9. The anti-displacement protrusion 9 is respectively placed at the top end of the upper linkage rack 6 and the bottom end of the lower linkage rack 7, and respectively moves with the upper linkage rack 6 and the lower linkage rack 7 to form a directional friction connection with the inner walls of the upper rail 1 and the lower rail 3.

[0029] By employing the anti-deviation convex edge 9, the anti-deviation convex edge can move directionally left and right along the upper rail 1 and lower rail 3 respectively during the opening and closing of the slide rail. This allows the upper bead nest group 4, lower bead nest group 5, and synchronous linkage group to slide directionally between the middle rail 2 and the upper rail 1, and between the middle rail 2 and the lower rail 3 respectively, thus preventing deviation during operation.

[0030] The anti-offset protrusion 9 is integrally formed on the top of the left and right sides of the upper linkage rack 6 and the bottom of the left and right sides of the lower linkage rack 7.

[0031] Furthermore, the anti-offset convex edge 9 is configured as a bridge-type convex edge.

[0032] In this way, the anti-offset convex edge 9 of this structure reduces running resistance and improves the stability of the slide rail transmission.

[0033] Reference Figures 1 to 5As shown, further detailed, the anti-detachment connector also includes an upper buffer stop 10 and a lower buffer stop 11. The upper buffer stop 10 is respectively provided on the left and right sides of the upper linkage rack 6, and the lower buffer stop 11 is respectively provided on the left and right sides of the lower linkage rack 7. The front end of the middle rail 2 and the rear end of the upper rail 1 are respectively provided with upper stop protrusions 12 that are elastically connected to the corresponding upper buffer stop 10 as they open and close. The rear end of the middle rail 2 and the front end of the lower rail 3 are respectively provided with lower stop protrusions 13 that are elastically connected to the corresponding lower buffer stop 11 as they open and close.

[0034] The upper buffer stop 10 and the lower buffer stop 11 provide a buffering and stopping effect for the slide rail, preventing collisions during load operation, reducing noise generation, and improving product performance.

[0035] Reference Figures 1 to 5 As shown, in further detail, the upper linkage rack 6 and the lower linkage rack 7 each have raised teeth 14 for meshing with the synchronous gear 8 under load.

[0036] The upper and lower linkage racks 6 and 7 using this structure utilize their heightened teeth 14 to prevent the synchronizing gear 8 from disengaging from the upper and lower linkage racks 6 and 7 under load. This ensures reliability, practicality, synchronous operation, and the quality of the slide rail.

[0037] Furthermore, the upper bead nest group 4 and the lower bead nest group 5 are respectively located at the front end and the lower end of the upper linkage rack 6 and the lower linkage rack 7, and respectively form an L-shaped upper transmission group and an L-shaped lower transmission group with the upper linkage rack 6 and the lower linkage rack 7.

[0038] The upper bead nest group 4 and the lower bead nest group 5 are combined with the upper linkage rack 6 and the lower linkage rack 7 respectively, which is convenient for assembly, easy to operate, and can ensure operational stability and reliability.

[0039] The above specific embodiments are only specific implementations of the present utility model with better effects. Any structure that is the same as or equivalent to the slide rail transmission mechanism with anti-detachment function of the present utility model is within the protection scope of the present utility model.
