Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically a universal slide rail transmission and installation mechanism. 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 sliding, a synchronous drive assembly and a ball bearing assembly are added to the drawer slides. The ball bearing assembly includes 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, and the lower ball bearing assembly is slidably connected between the lower and middle rails. The synchronous drive assembly includes a mounting bracket and gears. The upper ball bearing assembly is integrally connected to the upper rack, and the lower ball bearing assembly is integrally connected to the lower rack. The mounting bracket is fastened to the middle rail, and the gears rotate linearly on the upper and lower racks while simultaneously engaging with the mounting bracket. This design is simple in structure and offers high transmission stability.

[0004] However, the above-mentioned slide rail drive installation structure has the following shortcomings in practical applications:

[0005] 1) Since the upper and lower bead nest components are integrally formed with the upper and lower racks respectively, they are manufactured as a whole, resulting in a large volume and high precision requirements, which increases manufacturing costs.

[0006] 2) Since the upper and lower bead nest components are integrally formed with the upper and lower racks respectively, they can only be assembled on slide rails of specific specifications, resulting in poor versatility. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal slide rail transmission installation mechanism. It has a simple structure, adopts a universal segmented assembly method, is easy and quick to operate, has a stable connection, high synchronization, and can adapt to the use of slide rails of different specifications. It is flexible in use, highly applicable, and ensures the product's performance.

[0008] The purpose of this invention is achieved as follows: A universal slide rail transmission installation mechanism includes an upper rail, a middle rail, and a lower rail connected in sequence. An upper transmission assembly and a lower transmission assembly are slidably connected between the middle rail and the upper and lower rails, respectively. The upper transmission assembly includes an upper synchronous transmission component and an upper bead socket assembly, and the lower transmission assembly includes a lower synchronous transmission component and a lower bead socket assembly. The middle rail is provided with a synchronous gear that meshes with the upper and lower synchronous transmission components. The upper and lower synchronous transmission components are respectively provided with universal snap-fit ​​holes for the upper and lower bead socket assemblies to be universally guided and snapped into. Positioning grooves are provided on both sides of the universal snap-fit ​​holes. The upper and lower bead socket assemblies are respectively provided with snap-fit ​​protrusions that can be inserted into the universal snap-fit ​​holes and matched with the corresponding positioning grooves for snap-fit.

[0009] Based on the above optimization, the fastening protrusion is provided with a limiting protrusion to prevent it from disengaging from the universal snap-fit ​​hole. The limiting protrusion is integrally formed on the end of the fastening protrusion and can be guided in with the fastening protrusion to lock and connect to the corresponding positioning groove.

[0010] Based on the above optimization, the upper bead nest group is segmented and located at the front and rear ends of the upper synchronous transmission component.

[0011] Based on the above optimization, the upper synchronous transmission component includes an upper mounting bracket. The upper end of the upper mounting bracket has several universal snap-fit ​​holes for laterally guiding and fastening the upper bead assembly. The lower end of the upper mounting bracket is provided with an upper rack that meshes with the synchronous gear.

[0012] Based on the above optimization, the upper mounting frame is axially rolled with several upper rolling wheels, and the upper rolling wheels slide with the upper rail as the upper mounting frame moves.

[0013] Based on the above optimization, the lower bead nest group is distributed in front and rear sections at the front and rear ends of the lower synchronous transmission component.

[0014] Based on the above optimization, the lower synchronous transmission component includes a lower mounting bracket. The lower end of the lower mounting bracket has several universal snap-fit ​​holes for laterally guiding and fastening the lower bead assembly. The lower end of the lower mounting bracket is provided with a lower rack that meshes with the synchronous gear.

[0015] Based on the above optimization, the lower mounting bracket is axially rolled with a number of lower rolling wheels, and the lower rolling wheels slide with the lower rail as the lower mounting bracket moves.

[0016] The advantages of this utility model are:

[0017] 1) Through the structural cooperation of the snap-fit ​​protrusion and the universal snap-fit ​​hole and positioning groove, the upper bead nest group and the lower bead nest group can be snapped on the left or right side of the upper synchronous transmission component and the lower synchronous transmission component according to the actual application. The connection is stable, the synchronization is high, and the assembly is universal, making the operation convenient and quick, and highly flexible.

[0018] 2) Due to the use of snap-fit ​​protrusions and universal snap-fit ​​holes and positioning grooves, the upper and lower bead nest groups can be assembled in sections on the upper and lower synchronous transmission components according to actual applications. This allows for flexible installation on slide rails of different sizes, ensuring the product's performance. 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 6As shown, the universal slide rail transmission installation mechanism of this utility model includes an upper rail 1, a middle rail 2, and a lower rail 3 connected in sequence. An upper transmission assembly and a lower transmission assembly are slidably connected between the middle rail 2 and the upper rail 1 and lower rail 3, respectively. The upper transmission assembly includes an upper synchronous transmission component 4 and an upper bead socket assembly 5, and the lower transmission assembly includes a lower synchronous transmission component 6 and a lower bead socket assembly 7. The middle rail 2 is provided with a synchronous gear 8 that meshes with the upper synchronous transmission component 4 and the lower synchronous transmission component 6. The upper synchronous transmission component 4 and the lower synchronous transmission component 6 are each provided with universal snap-fit ​​holes 9 for the left and right universal guide snap-fit ​​of the upper bead socket assembly 5 and the lower bead socket assembly 7. Positioning grooves 91 are provided on both sides of the universal snap-fit ​​holes 9. The upper bead socket assembly 5 and the lower bead socket assembly 7 are each provided with snap-fit ​​protrusions 10 that can be inserted into the universal snap-fit ​​holes 9 and mate with the corresponding positioning grooves 91 for snap-fit.

[0027] In this way, through the structural cooperation of the snap-fit ​​protrusion 10 with the universal snap-fit ​​hole 9 and the positioning groove 91, the upper bead nest group 5 and the lower bead nest group 7 can be snapped onto the left or right side of the upper synchronous transmission component 4 and the lower synchronous transmission component 6 according to the actual application. The connection is stable, the synchronization is high, and the assembly is universal, making the operation convenient and quick, and highly flexible.

[0028] Furthermore, the snap-fit ​​protrusion 10 is provided with a limiting protrusion 101 to prevent disengagement from the universal snap-fit ​​hole 9. The limiting protrusion 101 is integrally formed on the end of the snap-fit ​​protrusion 10 and can be inserted with the snap-fit ​​protrusion 10 to lock onto the corresponding positioning groove 91. The structure is simple, highly versatile, and enhances the connection stability, ensuring the synchronous operation of the slide rail.

[0029] Reference Figures 1 to 6 As shown, further detailed, the upper bead nest group 5 is segmented and located at the front and rear ends of the upper synchronous transmission member 4; the lower bead nest group 7 is segmented and located at the front and rear ends of the lower synchronous transmission member 6.

[0030] The upper synchronous transmission component 4 includes an upper mounting bracket, and the lower synchronous transmission component 6 includes a lower mounting bracket. The upper end of the upper mounting bracket has several universal snap-fit ​​holes 9 for laterally inserting and fastening the upper bead assembly 5, and the lower end of the upper mounting bracket has an upper rack 11 that meshes with the synchronous gear 8. The lower end of the lower mounting bracket has several universal snap-fit ​​holes 9 for laterally inserting and fastening the lower bead assembly 7, and the lower end of the lower mounting bracket has a lower rack 13 that meshes with the synchronous gear 8.

[0031] The structure of the snap-fit ​​protrusion 10 and the universal snap-fit ​​hole 9 and positioning groove 91 allows the upper bead nest group 5 and the lower bead nest group 7 to be assembled in sections on the upper synchronous transmission component 4 and the lower synchronous transmission component 6 according to the actual application. It can be adapted to be installed on slide rails of different sizes, making it flexible to use and ensuring the product's performance.

[0032] Meanwhile, the upper mounting frame is axially and rollingly connected to several upper rollers 12, and the lower mounting frame is axially and rollingly connected to several lower rollers 14. The upper rollers 12 slide and connect with the upper rail 1 as the upper mounting frame moves, and the lower rollers 14 slide and connect with the lower rail 3 as the lower mounting frame moves.

[0033] The use of the upper synchronous transmission component 4 and the lower synchronous transmission component 6 in this structure enhances assembly stability and improves operational stability and synchronization, ensuring the quality of the slide rail.

[0034] It is worth noting that the upper and lower mounting frames are structurally identical, and the upper bead nest group 5 and the lower bead nest group 7 are structurally identical bead nest groups. This allows the bead nest groups to be assembled on the mounting frames in a universal manner, both vertically and horizontally. The segmented assembly facilitates operation, reduces manufacturing costs, and further enhances the versatility of components, making them suitable for use with different specifications of slide rails.

[0035] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the universal slide rail transmission installation mechanism of the present utility model are within the protection scope of the present utility model.
