[0025] The present utility model will be further described below with reference to the drawings.

[0026] According to the attached Figures 1 to 6As shown in the figure, the anti-bounce device of the guide rail with a sound-absorbing effect of the present utility model includes a bounce component provided on the guide rail. The bounce component includes a base 1 installed on the fixed rail of the guide rail, an energy storage sliding module 2 with an energy storage function, and a toggle block 3 that is buckled or separated from the movable rail of the guide rail as it opens and closes. Among them, the energy storage sliding module 2 has a dial pin 23, and the base 1 is provided with a buffer sound-absorbing component 4 for the dial pin 23 to move upward in the locking direction at a reduced speed. The buffer sound-absorbing component 4 includes a sound-absorbing mounting seat 41 and a buffer sound-absorbing wheel 42. The sound-absorbing mounting seat 41 is installed at the rear end of the base 1, and the buffer sound-absorbing wheel 42 is connected to the sound-absorbing mounting seat 41. Moreover, the buffer sound-absorbing wheel 42 is provided with a plurality of fins 43 that rotate on the sound-absorbing mounting seat 41 under the push of the dial pin 23 and have dynamic friction with the sound-absorbing mounting seat 41. The plurality of fins 43 are evenly distributed on the buffer sound-absorbing wheel 42.

[0027] That is, when the drawer is about to close, the dial pin 23 slides upward in the locking direction under the action of the restoring elastic force of the energy storage sliding module 2. During this period, the dial pin 23 contacts the buffer sound-absorbing wheel 42 and pushes the buffer sound-absorbing wheel 42 to rotate. Under the action of the dynamic friction resistance between the buffer sound-absorbing wheel 42 and the sound-absorbing mounting seat 41, a stable damping force is provided. The buffer sound-absorbing wheel 42 effectively blocks the rapid sliding of the dial pin 23, so that the dial pin 23 slides gently and touches the synchronization device 5, with good buffer damping effect and effectively achieving the sound-absorbing function.

[0028] Refer to Figures 1 to 6 As shown in the figure, for further refinement, the base 1 is provided with a mounting groove 11 adapted for mating installation with the sound-absorbing mounting seat 41. The mounting groove 11 is provided with a convex column 12 that is buckled with the sound-absorbing mounting seat 41. The structure is simple, the installation is convenient, and the stability is enhanced. The sound-absorbing mounting seat 41 is provided with a damping boss 411 for providing a stable damping force. The buffer sound-absorbing wheel 42 is rotatably connected to the sound-absorbing mounting seat 41 and is in dynamic friction connection with the damping boss 411.

[0029] By using the sound-absorbing mounting seat 41 of this structure, a stable damping force can be provided, prompting the buffer sound-absorbing wheel 42 to conduct an effective damping force to the dial pin 23, thereby blocking the rapid sliding of the dial pin 23 towards the synchronization slider and avoiding the generation of collision sounds.

[0030] Refer to Figures 1 to 6 As shown in the figure, for further refinement, the fin 43 is provided with a vertical connection surface 431 that contacts the dial pin 23 and guides its upward movement in the locking direction. The vertical connection surface 431 is distributed on the inner side of the fin 43. Among them, the distance between the fins 43 is the same as the distance that the dial pin 23 moves to the locking position after closing and unlocking. In this way, each time after closing and unlocking, a fin 43 will block the rapid buffering of the dial pin 23 at the same position, ensuring the buffer sound-absorbing effect.

[0031] Refer toFigures 1 to 6 As shown, in further detail, the base 1 is provided with a synchronization device 5 for synchronous locking and synchronous unlocking, and the synchronization device 5 includes a synchronization movable block 51 and a transmission rod 52. The synchronization movable block 51 is connected to the base 1 by sliding forward and backward, and the transmission rod 52 is installed on the synchronization movable block 51 and swings forward and backward as the synchronization movable block 51 moves. The inner side of the synchronization movable block 51 and the base 1 form a locking position 6 for locking the dial pin 23, and the inner side of the synchronization movable block 51 is provided with an unlocking position 7 that is connected to the dial pin 23 and is synchronously unlocked under the elastic potential energy of the energy storage sliding module 2 to move forward. The transmission rod 52 is transmission-connected with a synchronization rod, and the synchronization rod is connected to a rebound component at the other end.

[0032] The rear end of the base 1 is provided with a limiting protrusion 13. The limiting protrusion 13 and the base 1 form a guide groove 14 for the setting pin 23 to move with the energy storage sliding module 2 to realize directional backward sliding, directional fall back locking, and press rebound to slide forward. One side of the limiting protrusion 13 and the inner side of the synchronous movable block 51 form a locking position 6.

[0033] Reference Figures 1 to 3 As shown, in further detail, the energy storage sliding module 2 includes an energy storage slider 21 and a tension spring 22. The dial pin 23 is rotatably connected to the rear end of the energy storage slider 21, and the two elastic ends of the tension spring 22 are respectively clamped on the front end of the energy storage slider 21 and the base 1. The energy storage slider 21 slides backward and is connected to the base 1 under the push of the dial block 3, and can push the sliding module connected to the synchronization device 5. The energy storage slider 21 slides forward and is connected to the base 1 under the action of the elastic potential energy of the tension spring 22, and the dial pin 23 pulls the synchronization device 5 to move forward.

[0034] When the drawer is closed, the toggle block 3 pushes the energy storage slider 21 to move backward along the base 1, and drives the pin 23 to move backward along the guide slot 14. During this period, the energy storage slider 21 pushes the synchronous movable block 51 of the synchronization device 5 to move backward. When the drawer is closed to the specified position, the toggle block 3 separates from the energy storage slider, and the pin 23 moves to the left end slot of the guide slot 14. Under the elastic force of the tension spring 22, the energy storage slider 21 pulls the pin 23 along the guide slot 14 to fall back toward the locking position 6.

[0035] When the drawer is opened, the drawer is pressed, and the pin 23 slides forward along the right end slot of the guide slot 14 and to the unlocking position 7 under the elastic force of the tension spring 22, so as to push the synchronous movable block 51 to move forward, thereby realizing synchronous unlocking of the rebound component. Then, after the pin 23 slides to the specified position, the pin 23 continues to move forward along the base 1 to fully open the drawer.

[0036] Through the structural coordination of the synchronization device 5 and the buffer and silencer component 4, the rebound components on both sides of the drawer can be locked and unlocked synchronously, thereby improving the operational stability and having a silencer function. The dual functions coexist and enhance the quality of product use.

[0037] Reference Figures 1 to 6 As shown, in further detail, the base 1 is equipped with an adjustment installation device 8 for adjusting the installation position, and the adjustment installation device 8 includes an adjustment installation plate 81 and an adjustment wheel 82. The adjustment wheel 82 is rotatably connected to the base 1, and the adjustment installation plate 81 is slidably mounted on the bottom surface of the base 1, and the adjustment installation plate 81 is provided with a plurality of adjustment protrusions 83 distributed at equal intervals in front and back, and the bottom surface of the adjustment wheel 82 is provided with a rotation groove 84. The adjustment wheel 82 rotates, and at the same time, the adjustment protrusion 83 is screwed into or out of the rotation groove 84 to drive the base 1 to move forward and backward relative to the adjustment installation plate 81.

[0038] By coordinating the structure of the adjusting installation device 8, the assembly position of the rebound component can be adjusted, reducing the probability of errors during production and assembly that make installation and use difficult, and improving the quality of product use.

[0039] The above-mentioned specific embodiments are only specific implementation methods with better effects of the utility model. Any structure that is the same or equivalent to the guide rail rebound device with noise reduction effect of the utility model is within the protection scope of the utility model.
