Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a guide rail rebound device with a silent effect. Background Art

[0002] The press-synchronized rebound device is often used as a functional accessory for hidden guide rails. It stores energy when closed and leaves space for pressing to unlock. By pressing the drawer, the drawer and other pull-out furniture are unlocked and rebounded, making the pull-out furniture automatically pop open. It is very convenient to use and improves safety.

[0003] However, the traditional pressing synchronous rebound device has the following shortcomings during use:

[0004] 1) When closing the energy storage or releasing the energy, the traditional push-to-rebound device will cause the drawer to collide directly with the cabinet body, generating loud noise and even damaging various components, reducing the stability of use and shortening the service life of the product.

[0005] 2) When a traditional push-to-rebound device slams a drawer shut, especially when the drawer is heavily loaded, the drawer will collide with the cabinet body at too high a speed, generating a loud noise. The drawer may even slide directly to the unlocked position under the excessive impact force, causing the drawer to be unable to lock and pop out, resulting in the product being unable to be used normally. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a guide rail rebound device with a silent effect. It has a simple structure, a silent effect, effectively reduces noise generation, and can ensure that the drawer is locked normally when it is overloaded and slammed shut, thereby enhancing the stability of use.

[0007] The inventive object of the utility model is achieved as follows: a guide rail rebound device with a silent effect, comprising a rebound component arranged on the guide rail, the rebound component comprising a base mounted on the fixed rail of the guide rail, an energy storage sliding module with an energy storage function, a toggle block that is buckled or separated from the movable rail of the guide rail as it is opened and closed, and a synchronization device that can synchronize the locking and unlocking of the rebound components on both sides, wherein the energy storage sliding module has a dial pin, the base is provided with a limiting boss and a buffer combination block, a sliding groove is formed between the limiting boss and the base for the dial pin to slide backward in a direction, fall back to lock in a direction, and slide forward by pressing the rebound as the drawer is opened and closed, the synchronization device is connected to the base for sliding back and forth, the synchronization device is provided with a convex edge block for locking or unlocking the dial pin, and the buffer combination block is respectively installed on the sides of the sliding groove, the convex edge block and the synchronization device.

[0008] According to the above optimization, the buffer combination block includes a buffer block and a protective block. The buffer blocks are respectively installed on one side of the sliding groove and the outer edge of the protruding block and are in soft contact with the setting needle. The protective blocks are respectively installed on the outer side of the synchronization device and are softly connected to the base.

[0009] According to the above optimization, the sliding groove includes a directional sliding groove position for causing the selector pin to slide inward as the drawer is closed, a directional return groove position for providing a gap between the selector pin and the limiting boss when the drawer is closed and enters the buffer stage, and an unlocking sliding groove position for unlocking the selector pin to slide outward when the drawer is pressed to release pressure. The buffer blocks are respectively located on one side of the directional return groove position and the unlocking sliding groove position and can be disassembled and assembled on the limiting boss and the base.

[0010] According to the above optimization, the synchronization device includes a synchronization movable block that can slide back and forth on the base, and the synchronization movable block is installed with a swing frame that swings back and forth as it moves, and the swing frame is connected to a synchronization rod connected to another rebound component. The convex edge block is arranged on the inner side of the synchronization movable block, and the convex edge block forms a locking position with the limit boss to lock the dial pin as the synchronization movable block moves backward. The convex edge block is provided with an unlocking position that is engaged with the dial pin and the dial pin is pulled forward by the elastic potential energy of the energy storage sliding module and is synchronously unlocked; the convex edge block and the unlocking position are respectively detachable and equipped with protective blocks.

[0011] According to the above optimization, the outer sides of the synchronous movable blocks can be detachably provided with protective blocks.

[0012] According to the above optimization, the base is provided with a buffer wheel for the setting pin to move slowly from the directional return slot of the sliding slot to the locking direction.

[0016] 2) Through the structural coordination of the buffer wheel, when the drawer is closed suddenly due to overload, the pin falls back on the sliding groove under the action of the reset elastic force of the energy storage sliding module and moves quickly in the locking direction. At this time, the pin contacts the buffer wheel and pushes the buffer wheel to rotate. The buffer wheel and the base generate friction damping force, which effectively slows down the sliding of the pin, has a good buffering effect, and further achieves a silent effect. During this period, the buffer wheel effectively guides the pin to move in the locking direction, with high stability in use, ensuring that the drawer is locked normally.

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] According to the attached Figures 1 to 6 As shown, the guide rail rebound device with a silent effect of the present invention includes a rebound component arranged on the guide rail, and the rebound 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, a toggle block 3 that is connected or separated with the movable rail of the guide rail as the drawer is opened and closed, and a synchronization device 4 that can synchronize the locking and unlocking of the rebound components on both sides. Among them, the energy storage sliding module 2 has a dial pin 5, and the base 1 is provided with a limiting boss 6 and a buffer assembly block. A sliding groove 7 is formed between the limiting boss 6 and the base 1 for the dial pin 5 to slide backward in a directional manner, fall back to lock in a directional manner, and slide forward by pressing the rebound as the drawer is opened and closed. The synchronization device 4 is connected to the base 1 in a forward and backward sliding manner. The synchronization device 4 is provided with a convex block 42 for locking or unlocking the dial pin 5. The buffer assembly block is respectively installed on the sliding groove 7, the convex block 42 and the side of the synchronization device 4.

[0025] Reference Figures 1 to 6As shown in the figure, the buffer assembly includes a buffer block 8 and a protective block 9. The buffer block 8 is respectively installed on one side of the sliding groove 7 and the outer edge of the protruding block 42 and softly contacts the setting pin 5. The protective block 9 is respectively installed on the outer side of the synchronization device 4 and softly connected to the base 1.

[0026] The sliding slot 7 includes a directional sliding slot 71 for directionally sliding the setting pin 5 inward as the drawer closes, a directional return slot 72 for creating a gap between the setting pin 5 and the limiting boss 6 during the drawer closing buffer phase, and an unlocking slot 73 for unlocking the setting pin 5 and sliding it outward when the drawer is pressed to release pressure. The buffer block 8 is located on either side of the directional return slot 72 and the unlocking slot 73, respectively, and can be detachably mounted on the limiting boss 6 and the base 1.

[0027] Furthermore, the energy storage sliding module 2 includes an energy storage slider 21 and a tension spring 22. The dial pin 5 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 to the front end of the energy storage slider 21 and the base 1. When the energy storage slider 21 is pushed by the dial block 3, it slides backward and connects to the base 1, while pushing the synchronous movable block 41 to move backward. When the energy storage slider 21 slides forward and connects to the base 1 under the elastic potential energy of the tension spring 22, the dial pin 5 pulls the synchronous movable block 41 forward.

[0028] Reference Figures 1 to 6 As shown, in further detail, the base 1 is provided with a buffer wheel 12 for the pin 5 to move slowly from the directional return slot 72 of the sliding slot 7 to the locking direction. The buffer wheel 12 is installed at the rear end of the base 1 and is rotationally frictionally connected to the base 1 under the push of the pin 5.

[0029] The synchronizing device 4 includes a synchronizing movable block 41 that can slide back and forth on the base 1. The synchronizing movable block 41 is mounted with a swing frame 43 that swings back and forth as it moves. The swing frame 43 is connected to a synchronizing rod connected to another rebound component. The protruding block 42 is disposed on the inner side of the synchronizing movable block 41. As the synchronizing movable block 41 moves backward, the protruding block 42 forms a locking position 10 with the limiting boss 6 to lock the setting pin 5. The protruding block 42 is also provided with an unlocking position 11 that engages with the setting pin 5 and is simultaneously unlocked by the elastic potential energy of the energy storage sliding module 2 when the setting pin 5 is pulled forward.

[0030] Furthermore, the convex block 42 and the unlocking block 11 are respectively detachably provided with a protective block 9. The outer sides of the synchronous movable block 41 are respectively detachably provided with a protective block 9.

[0031] When the drawer is energy-storage and closed, the setting pin 5 moves on the directional slide slot 71. When the drawer is closed and enters the buffer stage, due to the setting of the directional return slot 72, there is a gap between the setting pin 5 and the limit boss 6, so that the setting pin 5 can fall back smoothly and quickly under the action of the elastic potential energy of the energy-storage sliding module 2, and there is a certain space buffer time. At the same time, the setting pin 5 falls back and softly contacts the buffer block 8 installed in the directional return slot 72, which has a good buffering effect and reduces the generation of noise.

[0032] When the drawer enters the buffering stage, the setting pin 5 falls into the directional return slot 72 and contacts the buffer wheel 12. The return force of the tension spring 22 pushes the buffer wheel 12 to rotate. Guided by the buffer wheel 12, the setting pin 5 slowly slides to the locking position 10, ensuring proper locking of the drawer in the event of an overload or sudden slam. During this period, the locking buffer wheel 12 and the base 1 provide a certain deceleration damping force for the setting pin 5, causing it to gently contact the synchronous movable block 41, providing an effective silencing effect.

[0033] During this period, combined with the function of the protective block 9, the setting needle 5 and the synchronous movable block 41, or the synchronous movable block 41 and the base 1 can be in soft contact, further reducing the noise generated by the contact, and the silencing effect is obvious.

[0034] When the drawer is opened, the drawer is pressed, and the pin 5 passes over the raised edge 42. Under the elastic force of the tension spring 22, it slides forward to the unlocking latch 11, pushing the synchronous movable block 41 forward and achieving synchronous unlocking of the rebound component. Then, after the pin 5 has slid to the designated position, the unlocking latch 11 connects with the unlocking chute 73. Under the elastic force of the spring, the pin 5 continues to move forward along the unlocking chute 73, fully opening the drawer. This simple structure offers high operational stability. During this time, the buffer block 8 of the unlocking chute 73 cooperates with the pin 5 to ensure a soft contact between the unlocking chute 73, further enhancing the quieting effect.

[0035] The above specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the guide rail rebound device with silent effect of the present invention is within the protection scope of the present invention.
