Description
Technical Field
[0001] The utility model relates to the technical field of guide rails, in particular to a guide rail rebound device with an overload locking function. Background Art
[0002] The press-to-synchronize rebound device is commonly 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 can be 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 the drawer is slammed shut, especially when the drawer is overloaded, the pin slides directly to the unlocking position under the excessive impact force, causing the drawer to be unable to lock and pop out, making the drawer unable to close normally, with poor stability and potential safety hazards.
[0005] 2) When the drawer is slammed shut, especially when the drawer is heavily loaded, it will cause the drawer to collide directly with the cabinet body and produce loud noise, and even damage various components, thus affecting the service life of the product. Utility Model Content
[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a guide rail rebound device with an overload locking function. The device has a simple structure and can ensure that the drawer can be locked without being ejected when the drawer is closed violently under overload, thereby enhancing the stability of the structure and reducing the noise generated, thereby ensuring the quality of the product.
[0007] The inventive objective of the utility model is achieved as follows: a guide rail rebound device with an overload locking function, 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, and a toggle block that is buckled or separated from the movable rail of the guide rail as it is opened and closed, wherein the energy storage sliding module has a dial pin, and the base is provided with a heavy-load quick-closing anti-unhooking device, and the heavy-load quick-closing anti-unhooking device comprises a guide groove for the dial pin to move with the energy storage sliding module to realize directional backward sliding, directional fall back locking, and forward sliding by pressing rebound, and a reduction wheel for increasing the damping force of the dial pin operation, the reduction wheel is connected to the base by dynamic friction under the push of the dial pin, and a guide surface is provided on one side of the guide groove, so that an anti-unhooking guide groove position is formed in the guide groove for causing the dial pin to move in the opposite direction and away from the unlocking direction under the deceleration action of the reduction wheel.
[0008] According to the above optimization, the base 1 is provided with a limiting protrusion 3, and the limiting protrusion 3 is arranged at the rear end of the base 1 to form a guide groove 5, and the guide groove includes an upper locking guide groove, a fall-back guide locking groove, and an unlocking guide groove. The upper locking guide groove and the unlocking guide groove are distributed on both sides of the limiting protrusion, and the guide surface is obliquely arranged at the rear end of the fall-back guide locking groove, so that an anti-slip guide groove is formed between the fall-back guide locking groove and the unlocking guide groove.
[0009] According to the above optimization, the guide surface is gradually inclined from high to low in the direction from the upper locking guide slot to the unlocking guide slot to form a V-shaped anti-slip guide slot connecting the fall-back guiding locking slot and the unlocking guide slot.
[0010] According to the above optimization, the base is provided with a connecting protrusion, and an anti-unhooking elastic block is provided on one side of the setting pin. The anti-unhooking elastic block is slidingly connected to the connecting protrusion and can cause the setting pin to slide from the upper locking guide groove position to the anti-unhooking guide groove position under its elastic reaction.
[0011] According to the above optimization, a synchronization device is installed on the base for sliding forward and backward, and the synchronization device includes a synchronization movable block. A synchronization convex edge is provided on the inner side of the synchronization movable block. As the synchronization movable block moves backward, the synchronization convex edge forms a locking position connected to the anti-disengagement guide groove with the limit convex block. An unlocking position is provided at the end of the synchronization convex edge. When the shifting pin is pressed and rebounded, it passes over the synchronization convex edge and is engaged with the unlocking position, so that the shifting pin pulls the synchronization movable block forward under the action of the elastic potential energy of the energy storage sliding module, thereby connecting the unlocking position with the unlocking guide groove.
[0012] According to the above optimization, the synchronization device also includes a transmission rod and a synchronization rod, the synchronization movable block is connected to the base for sliding back and forth, the synchronization convex edge is arranged on the inner side of the synchronization movable block, the transmission rod is installed on the outer side of the synchronization movable block and swings back and forth as the synchronization movable block moves, the transmission rod is transmission-connected with the synchronization rod, and the synchronization rod is connected to a rebound component at the other end.
[0013] According to the above optimization, the energy storage sliding module includes an energy storage slider and a tension spring. The dial pin is rotatably connected to the rear end of the energy storage slider. The two elastic ends of the tension spring are respectively clamped on the front ends of the energy storage slider and the base. The energy storage slider slides backward under the push of the dial block and is connected to the base, and can push the synchronous active block connected to the synchronization device. The energy storage slider slides forward under the action of the elastic potential energy of the tension spring and is connected to the base, so that the dial pin pulls the synchronous active block of the synchronization device to move forward.
[0014] The advantages of the utility model are:
[0015] 1) By adding a heavy-duty quick-closing anti-disengagement hook device, with the structural cooperation between the reduction gear of this device and the anti-disengagement guide groove position, when closing forcefully under overload, due to the deceleration effect of the reduction gear, the dialing pin cannot slide into the anti-disengagement guide groove position all at once. By setting an appropriate damping force on the reduction gear, the dialing pin is still in the anti-disengagement guide groove position before the drawer closes in place. During this period, under the action of the guiding surface, the dialing pin moves in the reverse direction, thus moving away from the unlocking direction. When the mechanism stabilizes, under the action of the elastic potential energy of the tension spring, the dialing pin slides onto the locking position, realizing the normal closing of the drawer. This avoids the unlocking and tripping of the drawer when closing forcefully under overload, strengthens the structural stability in use, and ensures the normal use of the product.
[0016] 2) Using the heavy-duty quick-closing anti-disengagement hook device with this structure can not only ensure that the dialing pin is directly latched onto the locking position from the anti-disengagement guide groove position without falling onto the unlocking position, further solving the problem that the drawer cannot be locked and is ejected when closing under overload, but also can decelerate the dialing pin when closing forcefully under overload, reducing the generation of noise and enhancing the product use experience.

[0022] The present utility model will be further described below with reference to the accompanying drawings.
[0023] According to the appendix Figures 1 to 5As shown, the guide rail rebound device with overload locking function of the utility model comprises a rebound component arranged on the guide rail, and the rebound component comprises a base 1 installed on the fixed rail of the guide rail, an energy storage sliding module 2 with energy storage function, and a toggle block 10 that is buckled or separated with the movable rail of the guide rail as it is opened and closed. Among them, the energy storage sliding module 2 has a dial pin 23, and the base 1 is provided with a heavy-load quick closing anti-unhooking device. The heavy-load quick closing anti-unhooking device comprises a guide groove 5 for the dial pin 23 to slide backward in a directional manner, fall back and lock in a directional manner, and slide forward by pressing rebound as the energy storage sliding module 2 moves, and a reduction wheel 9 for increasing the damping force of the operation of the dial pin 23. The reduction wheel 9 is connected to the base 1 by dynamic friction under the push of the dial pin 23, and a guide surface 4 is provided on one side of the guide groove 5, so that an anti-unhooking guide groove position 51 is formed in the guide groove 5 for causing the dial pin 23 to move in the opposite direction and away from the unlocking direction under the deceleration action of the reduction wheel 9.
[0024] Reference Figures 1 to 5 As shown, in further detail, the base 1 is provided with a limiting protrusion 3, and the limiting protrusion 3 is arranged at the rear end of the base 1 to form a guide groove 5. The guide groove 5 includes an upper locking guide groove 52, a fall-back guide locking groove 53, and an unlocking guide groove 54. The upper locking guide groove 52 and the unlocking guide groove 54 are distributed on both sides of the limiting protrusion 3, and the guide surface 4 is obliquely arranged at the rear end of the fall-back guide locking groove 53, so that an anti-slip guide groove 51 is formed between the fall-back guide locking groove 53 and the unlocking guide groove 54.
[0025] The guide surface 4 is gradually inclined from high to low in the direction from the upper locking guide slot 52 to the unlocking guide slot 54 to form a V-shaped anti-slip guide slot 51 connecting the falling-back guiding locking slot 53 and the unlocking guide slot 54 .
[0026] Reference Figures 1 to 5 As shown, in further detail, a synchronization device 6 is installed on the base 1 to slide forward and backward. The synchronization device 6 includes a synchronization movable block 61, and a synchronization convex edge 611 is provided on the inner side of the synchronization movable block 61. As the synchronization movable block 61 moves backward, the synchronization convex edge 611 forms a locking position 7 connected to the anti-slip guide slot 51 with the limiting convex block 3. An unlocking position 8 is opened at the end of the synchronization convex edge 611. When the setting pin 23 is pressed and rebounded, it passes over the synchronization convex edge 611 and is clamped on the unlocking position 8, so that the setting pin 23 pulls the synchronization movable block 61 forward under the elastic potential energy of the energy storage sliding module 2, so that the unlocking position 8 is connected to the unlocking guide slot 54.
[0027] Furthermore, 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 ends 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 10, and can push the synchronous movable block 61 connected to the synchronization device 6. 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 synchronous movable block 61 of the synchronization device 6 to move forward.
[0028] That is, when the drawer is overloaded and slammed shut, the pin 23 falls back along the locking guide slot position of the guide slot 5 under the action of the elastic potential energy of the energy storage sliding module 2 to guide the locking slot position 53 to move. At the same time, the pin 23 contacts the reduction wheel 9 and pushes the reduction wheel 9 to rotate. Due to the deceleration effect of the reduction wheel 9, the pin 23 cannot slide to the anti-slip guide slot position 51 all at once. A suitable damping force is set on the reduction wheel 9 so that the pin 23 is still on the anti-slip guide slot position 51 before the drawer is closed. During this period, the pin 23 is moved in the opposite direction under the action of the guide surface 4, that is, the pin 23 continues to move upward to the left at the V-shaped corner position of the anti-slip guide slot position 51, thereby moving away from the unlocking direction. When the mechanism is stable, the pin 23 slides to the locking position 7 under the action of the elastic potential energy of the tension spring 22 to achieve normal closing of the drawer. This prevents the drawer from being unlocked and disengaged when it is overloaded and slammed shut, enhances the stability of the structure, and ensures the normal use of the product.
[0029] When the drawer is opened, the drawer is pressed, and after releasing the overload kinetic energy, the pin 23 passes over the synchronous convex edge 611 and falls back to the unlocking position 8 through the anti-slip guide slot 51, and pulls the synchronous movable block 61 forward under the action of the elastic potential energy of the energy storage slider 21 module, so as to realize the synchronous unlocking of the rebound components on both sides of the drawer. When the synchronous movable block 61 moves to the specified position, the unlocking position 8 is connected with the unlocking guide slot 54, so that the pin 23 slides from the unlocking position 8 to the unlocking guide slot 54, so that the drawer can be stably and smoothly opened completely.
[0030] In this way, the heavy-load quick-closing anti-unhooking device of this structure can ensure that the pin 23 is directly buckled on the locking position 7 from the anti-unhooking guide groove position 51 without falling on the unlocking position 8, further solving the problem that the drawer cannot be locked and is ejected when closed under overload, and can also slow down the pin 23 when it is closed under overload, reduce noise generation, and improve the product usage experience.
[0031] Reference Figures 1 to 5As shown, in the optimized solution, the base 1 is provided with a connecting lug 11, and one side of the dial pin 23 is provided with an anti-disengagement elastic block 231. While the anti-disengagement elastic block 231 is slidably connected to the connecting lug 11, it can, under its elastic reaction, urge the dial pin 23 to slide from the upper locking guide slot 52 to the anti-disengagement guide slot 51.
[0032] With the structural cooperation between the connecting lug 11 and the anti-disengagement elastic block 231, it is ensured that the dial pin 23 slides from the upper locking guide slot 52 and the anti-disengagement guide slot 51 to the upper locking position 7 when the drawer is slammed shut under heavy load, preventing the dial pin 23 from sliding reversely in the guide slot 5 and causing the drawer to fail to lock normally.
[0033] The above specific embodiments are only the specific embodiments with better effects of the present invention. Any structures that are the same as or equivalent to the guide rail rebound device with an overload locking function of the present invention are within the protection scope of the present invention.
