Description

Technical Field

[0001] The present invention relates to the technical field of drawer guides, and more particularly to a rebound synchronization device for hidden rails. Background Art

[0002] Currently, drawer guides are widely used on various desks. In order to make the drawer fit tightly against the cabinet body after closing to increase aesthetics, hidden slides are used in combination.

[0003] Among them, the existing hidden slides are equipped with push-button rebounders, which can provide assistance during the process of pulling out the drawer to make it easier to pull out. The push-button rebounder is installed on the fixed rail, and the movable rail is equipped with a toggle fork. The toggle fork engages or disengages with the push-button rebounder when the movable rail opens and closes on the fixed rail. The structure is simple and the use comfort is relatively good.

[0004] However, the above-mentioned traditional push-button rebounder has the following deficiencies in the use process:

[0005] 1) The problem of unlocking synchronization of the traditional rebounder. When pressing the movable rail, it is difficult for the rebounders installed on the left and right slides to achieve synchronous unlocking, resulting in the two sides of the drawer not being able to be pulled out synchronously, which is prone to jamming and affects the use.

[0006] 2) The problem of universality of the traditional rebounder. Only specific synchronous unlocking transmission parts adapted to the specific slide can be installed on the traditional rebounder, with poor applicability, complex structure, cumbersome assembly, which is likely to affect the movement of the slide and reduce the use quality. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a rebound synchronization device for hidden rails, which has a simple structure, convenient assembly, high stability, can solve the problem of asynchronous pressing and rebounding of the rebounder, and at the same time does not affect the movement of the slide, ensuring the use quality of the slide.

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] According to the attached Figures 1 to 6 As shown, the rebound synchronization device for the hidden rail of the present invention comprises slide rails installed on the left and right sides of the drawer, the slide rails comprise a movable rail 1 and a fixed rail 2 which are slidably connected to each other in sequence, the movable rail 1 is provided with a toggle block 3, the fixed rail 2 is provided with a press rebounder 4, the toggle block 3 is engaged or separated with the press rebounder 4 during opening and closing. The press rebounder 4 is a prior art rebounder, and the specific technical disclosure is in CN202020756228.4.

[0028] Among them, a synchronous unlocker is provided between the slide rails to synchronously unlock the pressing rebounder 4, and the synchronous unlocker includes a synchronous rod 5, a synchronous trigger rack 6, and a synchronous trigger gear set 7. The two ends of the synchronous rod 5 are respectively clamped on the synchronous trigger gear set 7, and the synchronous trigger gear set 7 is respectively installed on the fixed rail 2 and meshes or disengages with the synchronous trigger rack 6 when opening and closing. The synchronous trigger rack 6 is respectively installed on the movable rail 1, and the synchronous trigger rack 6 drives the synchronous trigger gear set 7 to rotate when the pressing rebounder 4 is pressed to unlock, so as to drive the synchronous rod 5 to rotate.

[0029] In the optimized solution, the synchronous trigger gear group 7 includes a gear fixing box 71, a synchronous gear 72, and a connecting piece 73. The gear fixing box 71 is respectively installed on the fixed rail 2, the synchronous gear 72 shaft is connected to the gear fixing box 71, one end of the connecting piece 73 is clamped on the synchronous gear 72, and the other end of the connecting piece 73 is respectively mounted on the corresponding end of the synchronous rod 5.

[0030] That is, when the drawer is in the closed state, the left and right slide rails are in the closed state respectively through the synchronization rod 5, and the synchronization trigger gear set 7 and the synchronization trigger rack 6 are in the original state of meshing respectively. When the drawer is pressed, the movable rail 1 in the right slide rail moves forward in the direction A, and the pressing rebounder 4 is unlocked. At the same time, the synchronization gear 72 rotates driven by the synchronization rack, thereby driving the synchronization rod 5 to rotate. At this time, the rotational power is transmitted to the synchronization trigger gear set 7 of the left slide rail, and the synchronization gear 72 of the synchronization trigger gear set 7 of the left slide rail rotates to force the synchronization trigger rack 6 of the left slide rail and the movable rail 1 of the right slide rail to move to the same position in the same direction, thereby realizing the synchronous unlocking of the pressing rebounder 4.

[0031] When the drawer rebounds to open or closes, the synchronous trigger gear set 7 and the synchronous trigger rack 6 are out of meshing and separated from each other. Therefore, the synchronous unlocker of this structure can be installed alone on the slide rail with the pressing rebounder 4, and has a simple structure, convenient operation, and high versatility. Moreover, the synchronous unlocker of this structure only works when the pressing rebounder 4 is pressed to unlock or close, and does not affect the movement of the slide rail. The unlocking synchronization is high, the jamming phenomenon is avoided, the stability is improved, and the comfort of the drawer is ensured.

[0032] Reference Figures 1 to 6 As shown, in further detail, the left and right sides of the synchronous gear 72 are respectively provided with shafts 721 connected to the gear fixing box 71, wherein the shaft 721 on one side is provided with a shaft sleeve 722 sleeved on the connecting member 73, the shaft sleeve 722 is provided with a long groove 723, and the connecting member 73 is provided with a buckle 731 matched with the long groove 723. The structure is simple, effectively prevents disengagement, and improves the structural stability.

[0033] Meanwhile, the gear fixing box 71 is provided with an axial hole 711 which is connected to the shaft 721, and the axial hole 711 is provided with a notch which is smaller than the shaft diameter of the shaft 721, and spring pieces 712 which are used to be clamped on the shaft 721 are respectively provided on both sides of the notch, which effectively prevents the shaft from coming out, improves the structural stability, and is easy to install.

[0034] Reference Figures 1 to 6As shown in the figure, in the optimized solution, the synchronous unlocker is provided with an adjustment component for adjusting the front and rear installation positions of the gear fixing box 71. The adjustment component includes an adjustment wheel set and a connecting plate 8. The connecting plate 8 is installed on the fixed rail 2, and the gear fixing box 71 slides on the connecting plate 8. The adjustment wheel set is axially connected to the gear fixing box 71, and the driving end of the adjustment wheel set is connected to the connecting plate 8.

[0035] Among them, the adjustment wheel set includes an adjustment wheel 9 and a transmission column 10. The bottom surface of the adjustment wheel 9 is provided with a spiral groove 11. The transmission column 10 is arranged on the connecting plate 8 and relatively slides in the spiral groove 11 as the adjustment wheel 9 rotates, so as to drive the gear fixing box 71 to slide back and forth on the connecting plate 8.

[0036] That is, during assembly, rotate the adjustment wheel 9 to make the transmission column 10 move relative to the adjustment wheel 9 in the spiral groove 11, so as to drive the gear fixing box 71 to move back and forth relative to the connecting plate 8, thereby finely adjusting the meshing position between the synchronous gear 72 and the synchronous trigger rack 6, and achieving fine adjustment of the front and rear assembly positions of the movable rail 1. Improve the synchronization of the precise unlocking of the slide rails on both sides of the drawer, and enhance the use quality and competitiveness of the slide rails.

[0037] Moreover, in the moving direction of the movable rail 1, the connection line between the transmission column 10 and the center point of the adjustment wheel 9 is parallel to the moving direction of the slide rail, playing a self-locking function.

[0038] In addition, the surface of the adjustment wheel 9 is provided with a plurality of positioning grooves 14 distributed around the center, and the outer edge of the gear fixing box is provided with positioning posts 15 that are buckled in the positioning grooves 14. With the structural cooperation of the positioning grooves 14 and the positioning posts 15, it further ensures that the adjustment wheel 9 remains in place during the operation of the slide rail. At the same time, the transmission column 10 and the adjustment wheel 9 are tangent in the direction perpendicular to the slide rail, which can not only ensure the self-locking function, but also ensure that only by manually rotating the adjustment wheel 9 will the synchronous trigger gear set 7 displace.

[0039] Furthermore, the connecting plate 8 is provided with guide posts 12 for the front and rear sliding of the gear fixing box 71, and the gear fixing box 71 is provided with guide grooves 13 that slide in cooperation with the guide posts 12. Ensure the accuracy of the adjustment and the connection stability between the connecting plate 8 and the gear fixing box 71.

[0040] The above specific embodiments are only the specific embodiments with better effects of the present invention. Any structure that is the same as or equivalent to the anti-bounce synchronization device for the hidden rail of the present invention is within the protection scope of the present invention.
