Description

Technical Field

[0001] The present invention relates to the technical field of drawers, and in particular to a drawer guide rail device with press-rebound and soft-closing functions. Background Art

[0002] Drawers are a common type of furniture with powerful storage functions. Guide rails are usually installed on both sides of the drawer so that the drawer can be pushed and pulled freely and smoothly. The user only needs to manually apply pulling and pushing force to the drawer to drive the drawer to move on the guide rails, thereby opening or closing the drawer. However, existing drawers are opened or closed by pulling out and pushing in. The operation process is relatively cumbersome, and the pulling and pushing strokes are long, resulting in long operation times and extremely inconvenient use. In addition, existing drawers cannot realize the function of automatically popping out the drawer when pressing the drawer, and there is no buffering function when closing. The guide rails are easily damaged, making the drawer's function single and the operation time-consuming and labor-intensive, which seriously affects the user experience and convenience of the drawer. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned problems and provide a drawer guide device with press-rebound and gentle closing functions. The drawer guide device can make the drawer pop out automatically by pressing the drawer. The operation is simple and convenient, and it has a buffering function when closing, which can achieve gentle closing of the drawer, thereby giving users a good user experience.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A drawer guide rail device with push-rebound and soft-closing functions comprises guide rail mechanisms arranged on both sides of the drawer, a rebound device arranged on each guide rail mechanism, and a synchronization device for driving the rebound devices on both sides to move synchronously; wherein,

[0006] The guide rail mechanism includes a static guide rail and a movable guide rail arranged on the static guide rail and moving relative to the static guide rail;

[0007] The rebound device includes a mounting seat provided on the static guide rail, a rebound mechanism provided inside the mounting seat, a damping mechanism, and a trigger mechanism provided on the moving guide rail for triggering the rebound mechanism;

[0008] The rebound mechanism includes a trigger member slidably arranged on the mounting seat, a driving rod and a connecting member slidably arranged on the trigger member, a limiting mechanism arranged on the mounting seat for limiting the trigger member, a rebound spring arranged on the trigger member, and a hook rotatably arranged on the driving rod; wherein the sliding direction of the trigger member, the driving rod and the connecting member is the same as the sliding direction of the moving guide rail; one end of the rebound spring acts on the rear end of the driving rod, and the other end acts on the rear end of the trigger member; the front end of the driving rod and the rear end of the connecting member are connected by The locking structure is connected; the limiting mechanism includes a limiting toggle rod hinged on the mounting seat and a limiting torsion spring acting on the limiting toggle rod and the mounting seat, the elastic force of the limiting torsion spring causes the limiting toggle rod to be clamped on the trigger member; the driving rod and the limiting toggle rod are provided with a guide and separation assembly for guiding the limiting toggle rod to separate from the trigger member; the trigger member is provided with a rebound guide groove, the rebound guide groove is provided with a hook portion, the rebound guide groove is used to guide the hook to be hooked on the hook portion and to guide the hook to be separated from the hook portion;

[0009] The front end of the damping mechanism acts on the middle part of the trigger member, and the rear end acts on the rear end of the mounting seat;

[0010] The trigger mechanism includes a driving block provided on the movable guide rail; when the drawer is closed, the movable guide rail moves backward and the driving block contacts the front end of the connecting member;

[0011] The synchronization device is used to cause the driving rods in the two rebound devices to move synchronously.

[0012] The working principle of the drawer guide device with push-rebound and soft-closing functions is as follows:

[0013] When closing the drawer, the drawer is pushed and the moving guide rail moves with the drawer. Therefore, the moving guide rail will slide backward relative to the static guide rail, and the movement of the moving guide rail will drive the driving block on it to move. As it moves, the driving block will contact the front end of the connecting piece. At this time, the trigger piece remains stationary under the action of the limiting mechanism; as the moving guide rail continues to move backward, the driving block will push the connecting piece to slide backward on the trigger piece, and the backward sliding of the connecting piece will push the driving rod to slide backward on the trigger piece. The backward movement of the driving rod will compress the rebound spring, overcome the elastic force of the rebound spring and move backward, the driving rod moves backward and drives the hook to move. Since one end of the hook is rotatably connected to the driving rod, the hook will continue to move backward along the rebound guide groove and move backward across the hook portion. ; As the connecting piece and the driving rod continue to move backward, the guiding and separating assembly on the driving rod will guide the limit toggle rod away from the trigger piece, and the limit toggle rod will overcome the elastic force of the limit torsion spring and separate from the trigger piece. Under the elastic force of the rebound spring, the trigger piece and the driving rod, plus the elastic force of the damping mechanism, pull the trigger piece backward, and the trigger piece will move backward on the mounting seat. Relative to the trigger piece, the driving rod has a tendency to move forward; the elastic force of the damping mechanism also prompts the trigger piece to move backward, and combined with the action of the rebound spring, the trigger piece and the driving rod produce a certain relative movement, so that the hook will instantly hook on the hook part. At this time, the synchronizing device just contacts the driving rod, stops pushing the drawer, and realizes the function of gently closing the drawer.

[0014] When the drawer needs to be opened, the drawer is pressed, and the moving guide rail moves backward with the drawer, driving the driving block to move backward, and the driving block drives the connecting piece and the driving rod to slide backward on the trigger piece, and the driving rod drives the synchronous device to move at the same time; under the action of the rebound spring, the driving rod pushes the trigger piece to move backward. When the trigger piece moves backward on the mounting seat to the limit position (the rear end of the trigger piece is pressed against the end of the mounting seat), the trigger piece stops moving, and the driving block drives the connecting piece and the driving rod to continue moving backward. The rebound spring is compressed, and the hook is separated from the hook part. When the hand is released, the rebound spring extends, and the huge elastic force of the rebound spring drives the driving rod and the connecting piece to rebound forward, and overcomes the damping mechanism. The elastic force, under the inertia of the driving rod and the connecting part, drives the trigger part forward, so that the rebound mechanism returns to its initial state; in the above process, the driving rod moves forward, which will cause the guide separation component of the driving rod to separate from the limit toggle rod. When the trigger part also moves forward and passes the limit toggle rod, the elastic force of the limit toggle rod prompts the limit toggle rod to clamp the trigger part, keeping the trigger part in its initial state; in the process of the connecting part moving forward, it will drive the driving block to move forward, drive the moving guide rail to move forward, and finally realize the rebound opening of the drawer; in the process of pressing and rebounding, the movement of the driving rod will also drive the movement of the synchronization device, ensuring that the driving rods on both sides can ensure synchronous movement during pressing and rebounding.

[0015] A preferred solution of the present invention is that a pushing block is provided between the trigger member and the mounting seat, one end of the pushing block is rotatably connected to the middle part of the trigger member, and the other end is slidably and rotatably connected to the mounting seat; a setting pin is provided on the moving guide rail, and a snap-in groove is provided on the pushing block, and the lower end of the setting pin can be snapped into the snap-in groove. When the drawer is closed, the movable guide rail moves backward, which simultaneously drives the driving block and the dial pin to move. The driving block contacts the connecting piece, and the dial pin contacts the pushing block and is locked in the locking groove. Before the guide separation component on the driving rod triggers the limit mechanism, the trigger is in a stationary state. Since one end of the pushing block is rotatably connected to the middle part of the trigger, the dial pin pushes the pushing block to rotate on the trigger, so that the pushing block has a buffer distance, which ensures that the trigger will not be pushed to move before the limit toggle rod is separated from the trigger member; when the guide separation component on the driving rod triggers the limit mechanism, the trigger member, the pushing block and the dial pin will move together. In this process, under the action of the damping mechanism, the trigger member will first move backward, and under the action of the pushing block, the dial pin will move, driving the guide rail to move, accelerating the closing of the drawer, and with the action of the rebound spring, the function of quickly and gently closing the drawer is realized; when it is necessary to press the rebound to open the drawer, there is a virtual position between the dial pin and the pushing block, so that when the trigger member moves to the limit position, the movable guide rail can continue to drive the driving block to move, ensuring smooth rebound. By setting the above structure, when closing the drawer and then opening it, the user can directly pull out the drawer, the movable guide rail drives the moving pin to move, the moving pin drives the pushing block to move, the pushing block overcomes the elastic force of the damping mechanism and drives the trigger member to move, so that the rebound mechanism moves with the movable guide rail, which plays a good buffering role when closing and opening the drawer.

[0016] Preferably, the guide separation assembly includes a limit pin provided at the end of the limit toggle rod and a guide separation slot provided on the drive rod for guiding the movement of the limit pin. In the above structure, when the drive rod moves backward, the limit pin enters the guide separation slot from the rear end opening of the guide separation slot. As the drive rod moves, the guide separation slot guides the limit pin to move along the path of the guide separation slot. The limit pin drives the limit toggle rod to overcome the elastic force of the limit torsion spring and swing, so that the limit toggle rod is separated from the trigger member. When the drive rod moves forward, combined with the elastic force of the limit torsion spring, the limit toggle rod can be urged to limit the trigger member.

[0017] Preferably, the rebound guide groove includes a first linear guide groove at the front end, a buckle guide groove at the middle, an exit guide groove, and a second linear guide groove at the rear end; wherein the hook portion is located between the buckle guide groove and the exit guide groove; the front end of the buckle guide groove is connected to the first linear guide groove, and the rear end is connected to the second linear guide groove; the front end of the exit guide groove is connected to the first linear guide groove, and the rear end is connected to the second linear guide groove. In the above structure, when closing the drawer, as the drive rod moves backward, it drives the hook from the first linear guide groove into the buckle groove, and then, under the guidance of the buckle guide groove, into the second linear guide groove. When the trigger member is separated from the limit mechanism, the rebound spring causes the hook to hook onto the rear end of the hook portion. When a press rebound is required, the hook enters the exit guide groove, then returns from the exit guide groove to the first linear guide groove, and finally returns to its initial state. With the above structure, the drawer's press-and-rebound function is achieved.

[0018] Preferably, the damping mechanism includes a damper and a damping spring arranged in parallel with each other, wherein the front end of the damper acts on the middle portion of the trigger member and the rear end acts on the mounting seat; the front end of the damping spring acts on the middle portion of the trigger member and the rear end acts on the mounting seat. By providing the damper and damping spring, the damping effect can be increased, ensuring stable closing of the drawer and providing a certain degree of buffering against rebound.

[0019] Preferably, the synchronization device includes a synchronization rod and a synchronization component arranged on both sides of the synchronization rod, and the two synchronization components are respectively mounted on the mounting seats of two rebound devices; wherein, the synchronization component includes a synchronization cam rotatably arranged on the mounting seat, a synchronization pin shaft arranged on the synchronization cam, and a synchronization torsion spring; one end of the synchronization torsion spring acts on the mounting seat, and the other end acts on the synchronization cam, and the synchronization cam is connected to the synchronization rod; a limiting groove is provided on the mounting seat, and the synchronization cam, under the elastic force of the synchronization torsion spring, causes the protrusion of the synchronization cam to press against the limiting groove; the driving rod is provided with a synchronization guide groove for guiding the movement of the synchronization pin shaft. In the above structure, when the drawer is closed, the hook just catches the hook part, and at this time the synchronization pin just contacts the synchronization guide groove of the drive rod; when the drawer is pressed to rebound, when the trigger moves to the extreme position, the drive rod will also move backward, and the synchronization guide groove on the drive rod will guide the synchronization pin to move, driving the synchronization cam to overcome the synchronization torsion spring to move, and as the drive rod continues to move backward, it will drive the synchronization pin to move; when the hook is separated from the hook part, the forward movement of the drive rod and the elastic force of the synchronization torsion spring cause the synchronization cam to move in the opposite direction, and finally the synchronization device will return to the initial state; by setting the synchronization device, it can be ensured that the two sides of the drawer can pop out synchronously, so that the drive rods on both sides will not have inconsistent pop-up rates when the drawer pops out, resulting in jamming, thereby improving the service life of the rebound device.

[0020] Preferably, the engaging structure includes an engaging block provided at the front end of the driving rod and an engaging slot provided at the rear end of the connecting member; the engaging block and the engaging slot are mutually engaged. The engaging structure allows the driving rod to be connected to the connecting member, thereby enabling the driving rod and the connecting member to move together. Furthermore, the driving rod and the connecting member can be easily disassembled and repaired.

[0021] Preferably, the mounting base is provided with a guide groove for guiding the movement of the push block, the guide groove comprising a circular arc segment at the front end and a straight line segment at the rear end. The circular arc segment allows the push block to rotate on the trigger member and slide on the mounting base, thereby ensuring a certain buffer distance for the push block; the straight line segment allows the direction of movement of the push block to remain parallel to the direction of movement of the trigger member, thereby driving the trigger member to move.

[0022] Preferably, the static guide rail is connected to the mounting seat via a base plate. By providing the base plate, the rebound device can be mounted on the base plate, and the structure becomes very compact.

[0023] Preferably, the mounting base is provided with a position adjustment mechanism for adjusting the mounting position of the mounting base on the base plate. The position adjustment mechanism includes an adjustment screw disposed on the mounting base and an adjustment gear disposed in the middle of the adjustment screw. The base plate is provided with two adjustment blocks, which extend upwardly into the mounting base and contact the ends of the adjustment screw, respectively. With this structure, the adjustment gear is manually rotated to drive the adjustment screw. Under the action of the two adjustment blocks, the mounting base moves relative to the adjustment screw, thereby adjusting the position of the mounting base and achieving position adjustment of the rebound device.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The drawer guide device with press-rebound and soft-closing functions of the present invention, when closing the drawer, after the limit mechanism is separated from the trigger member, the trigger member and the driving rod are pulled backward by the elastic force of the rebound spring and the elastic force of the damping mechanism, so that the trigger member moves backward on the mounting seat, and the driving rod has a tendency to move forward relative to the trigger member; the elastic force of the damping mechanism also prompts the trigger member to move backward and the action of the rebound spring causes the trigger member and the driving rod to produce a certain relative movement, so that the hook is instantly hooked on the hook portion, completing the closing of the drawer; in this process, the rebound spring acts on the driving rod, which can play a good buffering role in the closing of the drawer, thereby realizing the function of soft closing of the drawer.

[0026] When the drawer is opened, the driving block drives the connecting member and the driving rod to slide backward on the trigger member, and the driving rod drives the synchronous device to move at the same time; under the action of the rebound spring, the driving rod pushes the trigger member to move backward; when the trigger member moves backward on the mounting seat to the limit position (the rear end of the trigger member is pressed against the end of the mounting seat), the trigger member stops moving, and the driving block drives the connecting member and the driving rod to continue moving backward, the rebound spring is compressed, and the hook is separated from the hook part; when the hand is released, the rebound spring extends, and the huge elastic force of the rebound spring drives the driving rod and the connecting member to rebound forward and overcome the elastic force of the damping mechanism. Under the inertia of the driving rod and the connecting member, the trigger member is also driven forward, so that the rebound mechanism returns to its initial state, thereby popping the drawer open; through the above arrangement, the user does not need to manually open the drawer, but only needs to apply pressure to the drawer in the closed state, which is more convenient to operate, thereby giving the user a good user experience.

[0027] 3. The drawer guide device with press-to-rebound and soft-closing functions in the present invention can ensure that both sides of the drawer can pop out synchronously by setting a synchronization device, so that the driving rods on both sides of the drawer will not be stuck due to inconsistent pop-up rates when the drawer pops out, thereby improving the service life of the rebound device.

[0045] See also Figures 1-14 The front end of the damping mechanism 5 acts on the middle portion of the trigger 6, and the rear end acts on the rear end of the mounting base 4. The damping mechanism 5 includes a damper 501 and a damping spring 502, which are arranged parallel to each other. The front end of the damper 501 acts on the middle portion of the trigger 6, and the rear end acts on the mounting base 4. The front end of the damping spring 502 acts on the middle portion of the trigger 6, and the rear end acts on the mounting base 4. The damper 501 and the damping spring 502 can enhance the damping effect, stabilize the drawer closing, and provide a certain buffering effect against rebound.

[0046] See also Figures 1-14 The trigger mechanism includes a driving block 14 arranged on the movable guide rail 102; the driving block 14 is welded to the side of the movable guide rail 102. During the drawer closing process, the movable guide rail 102 moves backward, and the driving block 14 contacts the front end of the connecting member 8.

[0047] See also Figures 1-14 and Figure 16-19The drawer guide device with press-rebound and soft-closing functions in this embodiment, when closing the drawer, after the limit mechanism 9 is separated from the trigger member 6, the trigger member 6 and the driving rod 7 are pulled backward by the elastic force of the rebound spring 10, plus the elastic force of the damping mechanism 5, and the trigger member 6 moves backward on the mounting seat 4, and the driving rod 7 has a tendency to move forward relative to the trigger member 6; the elastic force of the damping mechanism 5 also prompts the trigger member 6 to move backward and the action of the rebound spring 10, so that the trigger member 6 and the driving rod 7 produce a certain relative movement, so that the hook 11 will instantly hook on the hook portion 13, completing the closing of the drawer; in this process, the rebound spring 10 acts on the driving rod 7, which can play a good buffering role in the closing of the drawer, thereby realizing the function of soft closing of the drawer.

[0048] The drawer guide device with press-rebound and soft closing functions in this embodiment, by pressing the drawer, causes the driving block 14 to drive the connecting member 8 and the driving rod 7 to slide backward on the trigger member 6, and the driving rod 7 will drive the synchronization device 3 to move at the same time; under the action of the rebound spring 10, the driving rod 7 will push the trigger member 6 to move backward, and when the trigger member 6 moves backward on the mounting seat 4 to the limit position (the rear end of the trigger member 6 is pressed against the end of the mounting seat 4), the trigger member 6 stops moving, and the driving block 14 drives the connecting member 8 and the driving rod 7 to continue to move backward, and the rebound spring 10 is compressed, the hook 11 will separate from the hook portion 13, and when the hand is released, the rebound spring 10 extends, and the huge elastic force of the rebound spring 10 drives the driving rod 7 and the connecting member 8 to rebound forward, and overcomes the elastic force of the damping mechanism 5. Under the inertia of the driving rod 7 and the connecting member 8, the trigger member 6 is also driven forward, so that the rebound mechanism returns to its initial state, thereby popping the drawer open; through the above arrangement, the user does not need to manually open the drawer, but only needs to apply pressure to the drawer in the closed state, which is more convenient to operate, thereby giving the user a good user experience.

[0049] See also Figures 1-19A pushing block 15 is provided between the trigger member 6 and the mounting seat 4, one end of the pushing block 15 is rotatably connected to the middle part of the trigger member 6, and the other end is slidably and rotatably connected to the mounting seat 4; a setting pin 16 is welded on the moving guide rail 102, and a snap-in groove 1501 is provided on the pushing block 15, and the lower end of the setting pin 16 can be snapped into the snap-in groove 1501. In the above structure, when the drawer is closed, the movable guide rail 102 will move backward, which will simultaneously drive the movement of the driving block 14 and the dial pin 16. The driving block 14 will contact the connecting member 8, and the dial pin 16 will contact the pushing block 15 and snap into the snap-in groove 1501. Before the guide separation assembly on the driving rod 7 triggers the limit mechanism 9, the trigger member 6 is in a stationary state. Since one end of the pushing block 15 is rotatably connected to the middle part of the trigger member 6, the dial pin 16 pushes the pushing block 15 to rotate on the trigger member 6, so that the pushing block 15 has a buffer distance, which ensures that the trigger member 6 will not be pushed before the limit toggle rod 901 is separated from the trigger member 6. Movement; when the guide separation assembly on the driving rod 7 triggers the limit mechanism 9, the trigger member 6, the pushing block 15 and the dial pin 16 will move together. In this process, under the action of the damping mechanism 5, the trigger member 6 will first move backward, and under the action of the pushing block 15, the dial pin 16 will be pulled to move, driving the guide rail 102 to move, accelerating the closing of the drawer, and with the action of the rebound spring 10, the function of quickly and gently closing the drawer is realized; when it is necessary to press the rebound to open the drawer, there is a virtual position between the dial pin 16 and the pushing block 15, so that when the trigger member 6 moves to the limit position, the moving guide rail 102 can continue to drive the driving block 14 to move, ensuring that the rebound proceeds smoothly. By setting the above structure, when closing the drawer and then opening it, the user can directly pull out the drawer or press the drawer to bounce it out. When pulling the drawer out, the movable guide rail 102 drives the dial pin 16 to move, and the dial pin 16 drives the push block 15 to move. The push block 15 overcomes the elastic force of the damping mechanism 5 and drives the trigger member 6 to move, so that the rebound mechanism moves with the movable guide rail 102, which plays a good buffering role when closing and opening the drawer.

[0050] See also Figure 4-Figure 5 The setting pin 16 is located behind the driving block 14, and the height of the lower end of the setting pin 16 is higher than the height of the lower end of the driving block 14. The purpose is to ensure that when the setting pin 16 moves backward, it can pass over the connecting member 8, and the driving block 14 can smoothly contact the connecting member 8, thereby pushing the connecting member 8 to move.

[0051] See also Figures 1-19The mounting base 4 is provided with a guide groove 17 for guiding the movement of the push block 15. The guide groove 17 includes a circular arc segment 1701 at the front end and a straight line segment 1702 at the rear end. The provision of the circular arc segment 1701 allows the push block 15 to rotate on the trigger member 6 and slide on the mounting base 4, thereby ensuring a certain buffer distance for the push block 15. The provision of the straight line segment 1702 allows the direction of movement of the push block 15 to remain parallel to the direction of movement of the trigger member 6, thereby driving the trigger member 6 to move.

[0052] See also Figures 1-19 The push block 15 is rotatably connected to the middle portion of the trigger member 6 via a rotating shaft 19. The push block 15 slides and rotates in conjunction with the guide slot 17 via a sliding shaft 18. The axis of the straight segment 1702 is parallel to the sliding direction of the trigger member 6, and the moving trajectory of the rotating shaft 19 coincides with the straight segment 1702. This allows the push block 15 to drive the trigger member 6, or the trigger member 6 to drive the push block 15, thereby driving the setting pin 16 and the movable guide rail 102, ensuring that all components can be linked together.

[0053] See also Figure 15 A spring piece 1502 is provided on the side of the snap-in slot 1501 of the pushing block 15, and its purpose is to facilitate the needle 16 to pass over the spring piece 1502 and enter the snap-in slot 1501.

[0054] See also Figures 1-19 The guide separation assembly includes a limit pin 20 provided at the end of the limit toggle rod 901 and a guide separation slot 21 provided on the drive rod 7 for guiding the movement of the limit pin 20. In the above structure, when the drive rod 7 moves backward, the limit pin 20 will enter the guide separation slot 21 from the rear end opening of the guide separation slot 21. As the drive rod 7 moves, the guide separation slot 21 will guide the limit pin 20 to move along the path of the guide separation slot 21. The limit pin 20 will drive the limit toggle rod 901 to overcome the elastic force of the limit torsion spring 902 and swing, so that the limit toggle rod 901 is separated from the trigger member 6; when the drive rod 7 moves forward, combined with the elastic force of the limit torsion spring 902, the limit toggle rod 901 can be prompted to limit the trigger member 6.

[0055] See also Figure 17The guide and separation groove 21 includes a linear guide and separation groove 2101 at the front end and an inclined guide and separation groove 2102 at the rear end. The rear end of the inclined guide and separation groove 2102 has an opening for guiding the limit pin 20. The inclined guide and separation groove 2102 is inclined forward in a direction gradually away from the trigger member 6. This is to ensure that the inclined guide and separation groove 2102 can effectively guide the limit pin 20 away from the trigger member 6, thereby driving the limit toggle rod 901 to separate from the trigger member 6.

[0056] See also Figures 1-19 The limit toggle lever 901 has a protrusion 9011 on the end away from the limit pin 20, and the mounting seat 4 is provided with a limit block 22. Under the elastic force of the limit torsion spring 902, the protrusion 9011 abuts against the limit block 22. The rear end of the trigger member 6 is provided with a limit slot 601. Under the elastic force of the limit torsion spring 902, the end of the limit toggle lever 901 extends into the limit slot 601. By providing the above mechanism, the protrusion 9011 and the limit block 22 can limit the depth of the limit toggle lever 901 in the limit slot 601, ensuring that the limit toggle lever 901 only limits the trigger member 6 in the front-to-back direction. When the limit toggle lever 901 separates from the trigger member 6, the sliding of the trigger member 6 is facilitated.

[0057] See also Figure 18-19 The rebound guide groove 12 includes a first linear guide groove 1201 at the front end, a buckle guide groove 1202 at the middle, an exit guide groove 1203 and a second linear guide groove 1204 at the rear end; wherein, the hook portion 13 is located between the buckle guide groove 1202 and the exit guide groove 1203; the front end of the buckle guide groove 1202 is connected to the first linear guide groove 1201, and the rear end is connected to the second linear guide groove 1204; the front end of the exit guide groove 1203 is connected to the first linear guide groove 1201, and the rear end is connected to the second linear guide groove 1204. In the above structure, when closing the drawer, as the drive rod 7 moves backward, it drives the hook 11 from the first linear guide groove 1201 and then, guided by the buckling guide groove 1202, enters the second linear guide groove 1204. When the trigger member 6 separates from the limit mechanism 9, the rebound spring 10 causes the hook 11 to hook onto the rear end of the hook portion 13. When a push-to-rebound function is required, the hook 11 enters the exit guide groove 1203 and then returns from the exit guide groove 1203 to the first linear guide groove 1201, ultimately returning to its initial state. The above structure realizes the drawer's push-to-rebound function.

[0058] See also Figure 18-19The axis of the first linear guide groove 1201 and the axis of the second linear guide groove 1204 are not collinear. The front end of the hook portion 13 is provided with a guiding inclined surface 12021 for guiding the hook 11 on the first linear guide groove 1201 into the guide groove 1202; the rear end of the hook portion 13 is provided with a ">"-shaped hook groove 12022. The above-mentioned ">"-shaped hook groove 12022 can play a hooking role for the hook 11. Combined with the fact that the axis of the first linear guide groove 1201 and the axis of the second linear guide groove 1204 are not collinear, the hook position of the ">"-shaped hook groove 12022 is misaligned with the axis of the second linear guide groove 1204, thereby guiding the hook 11 into the exit guide groove 1203 and realizing the hooking and rebound functions of the hook 11.

[0059] See also Figure 17 The drive rod 7 is provided with a mounting slot 701, which is provided with an arc-shaped opening slot 702. The front end of the hook 11 is rotatably connected to the bottom surface of the mounting slot 701, and the rear end extends from the arc-shaped opening slot 702 into the rebound guide slot 12. The purpose of adopting this structure is to enable the hook 11 to rotate on the drive rod 7, thereby allowing the hook 11 to move smoothly within the rebound guide slot 12. The mounting slot 701 is also provided with a mounting plate 703 to prevent the hook 11 from falling out of the mounting slot 701.

[0060] See also Figures 1-14 and Figure 17The synchronizing device 3 is used to promote the synchronous movement of the driving rods 7 in the two rebound devices 2; the synchronizing device 3 includes a synchronizing rod 301 and a synchronizing assembly arranged on both sides of the synchronizing rod 301, and the two synchronizing assemblies are respectively mounted on the mounting seats 4 of the two rebound devices 2; wherein, the synchronizing assembly includes a synchronizing cam 302 rotatably arranged on the mounting seat 4, a synchronizing pin 303 arranged on the synchronizing cam 302, and a synchronizing torsion spring 304; one end of the synchronizing torsion spring 304 acts on the mounting seat 4, and the other end acts on the synchronizing cam 302, and the synchronizing cam 302 is connected to the synchronizing rod 301; a limiting groove 23 is provided on the mounting seat 4, and the synchronizing cam 302 is caused to snap into the limiting groove 23 under the elastic force of the synchronizing torsion spring 304; a synchronizing guide groove 24 is provided on the driving rod 7 for guiding the movement of the synchronizing pin 303. After the drawer is closed, the hook 11 just catches the hook portion 13, and the synchronous pin 303 just contacts the synchronous guide groove 24 of the driving rod 7; when the drawer is pressed to rebound, the trigger member 6 moves to the extreme position, and the driving rod 7 will also move backward. The synchronous guide groove 24 on the driving rod 7 will guide the synchronous pin 303 to move, driving the synchronous cam 302 to overcome the synchronous torsion spring 304 to move. As the driving rod 7 continues to move backward, the synchronous pin 303 will be driven to move; when the hook 11 is separated from the hook portion 13, the forward movement of the driving rod 7 and the elastic force of the synchronous torsion spring 304 cause the synchronous cam 302 to move in the opposite direction, and finally the synchronous device 3 will also return to the initial state; by setting the synchronous device 3, it can be ensured that the two sides of the drawer can pop out synchronously, so that the driving rods 7 on both sides will not have inconsistent pop-up rates when the drawer pops out, resulting in jamming, thereby improving the service life of the rebound device 2.

[0061] See also Figure 7 The engaging structure includes an engaging block 25 provided at the front end of the driving rod 7 and an engaging slot 26 provided at the rear end of the connecting member 8; the engaging block 25 and the engaging slot 26 are mutually engaged. The engaging structure allows the driving rod 7 and the connecting member 8 to be connected, thereby enabling the driving rod 7 and the connecting member 8 to move together. At the same time, it also facilitates the disassembly of the driving rod 7 and the connecting member 8, making them easy to disassemble and repair.

[0062] See also Figure 1-Figure 5 The static guide rail 101 is connected to the mounting seat 4 via a base plate 27. By providing the base plate 27, the rebound device 2 can be mounted on the base plate 27, and the structure becomes very compact.

[0063] See also Figures 1-9The mounting base 4 is provided with a position adjustment mechanism for adjusting the mounting position of the mounting base 4 on the base plate 27. The position adjustment mechanism includes an adjustment screw 28 disposed on and coupled to the mounting base 4, and an adjustment gear 29 disposed in the middle of the adjustment screw 28. The base plate 27 is provided with two adjustment blocks 30, which extend upwardly into the mounting base 4 and contact the ends of the adjustment screw 28, respectively. With this structure, the adjustment gear 29 is manually rotated to drive the adjustment screw 28. Under the action of the two adjustment blocks 30, the mounting base 4 moves relative to the adjustment screw 28, thereby adjusting the position of the mounting base 4 and achieving position adjustment of the rebound device 2.

[0064] See also Figures 1-9 The static guide rail 101 is fixedly connected to the base plate 27 by rivets 31, and the mounting seat 4 is connected to the base plate 27 by screws. The base plate 27 is provided with a long hole 2701 at the position corresponding to the screw, so that the rebound device 2 can be fixed by the screw after the adjustment mechanism adjusts the position of the rebound device 2.

[0065] See also Figures 1-9 A mounting cover 32 is provided on the mounting seat 4, and an adjustment opening 3201 is provided at a position corresponding to the mounting cover 32 and the adjusting gear 29. The purpose is to expose the adjusting gear 29 on the adjusting opening 3201, so as to facilitate the position adjustment of the rebound device 2. The mounting cover 32 can also play a sealing and protective role for the components of the rebound device 2.

[0066] See also Figures 1-14 and Figure 16-19 The working principle of the drawer guide device with push-rebound and soft-closing functions is as follows:

[0067] When closing the drawer, the drawer is pushed and the moving guide rail 102 moves with the drawer. Therefore, the moving guide rail 102 will slide backward relative to the static guide rail 101, and the movement of the moving guide rail 102 will drive the driving block 14 thereon to move. As it moves, the driving block 14 will contact the front end of the connecting member 8. At this time, the triggering member 6 remains stationary under the action of the limiting mechanism 9; as the moving guide rail 102 continues to move backward, the driving block 14 will push the connecting member 8 to slide backward on the triggering member 6, and the backward sliding of the connecting member 8 will push the driving rod 7 to slide backward on the triggering member 6. The backward movement of the driving rod 7 will compress the rebound spring 10, overcome the elastic force of the rebound spring 10 and move backward, the driving rod 7 moves backward and drives the hook 11 to move. Since one end of the hook 11 is rotatably connected to the driving rod 7, the hook 11 will move backward along the rebound guide groove 12 and continue to move over the hook portion 13 , the cam 6 is released and the drawer 6 is unlocked, and the drawer 6 is unlocked, and the drawer 6 is unlocked.

[0068] When the drawer needs to be opened, the drawer is pressed, and the movable guide rail 102 moves backward with the drawer, driving the driving block 14 to move backward. The driving block 14 drives the connecting member 8 and the driving rod 7 to slide backward on the trigger member 6, and the driving rod 7 drives the synchronization device 3 to move at the same time; under the action of the rebound spring 10, the driving rod 7 pushes the trigger member 6 to move backward. When the trigger member 6 moves backward on the mounting seat 4 to the limit position (the rear end of the trigger member 6 is pressed against the end of the mounting seat 4), the trigger member 6 stops moving, and the driving block 14 drives the connecting member 8 and the driving rod 7 to continue to move backward. The rebound spring 10 is compressed, and the hook 11 is separated from the hook portion 13. When the hand is released, the rebound spring 10 extends, and the huge elastic force of the rebound spring 10 drives the driving rod 7 and the connecting member 8 to rebound forward and overcome the resistance The elastic force of the mechanism 5, under the inertia of the driving rod 7 and the connecting member 8, drives the trigger member 6 to move forward, so that the rebound mechanism returns to the initial state; in the above process, the driving rod 7 moves forward, which will cause the guide separation assembly of the driving rod 7 to separate from the limit toggle rod 901. When the trigger member 6 also moves forward and passes the limit toggle rod 901, the elastic force of the limit torsion spring 902 prompts the limit toggle rod 901 to clamp the trigger member 6, keeping the trigger member 6 in the initial state; in the process of the connecting member 8 moving forward, it will drive the driving block 14 to move forward, drive the moving guide rail 102 to move forward, and finally realize the rebound opening of the drawer; in the process of pressing and rebounding, the movement of the driving rod 7 will also drive the movement of the synchronization device 3, ensuring that the driving rods 7 on both sides can ensure synchronous movement when pressing and rebounding.
