Description

Technical Field

[0001] The present invention specifically relates to a furniture rebound device, in particular to a furniture rebound device. Background Art

[0002] In the sliding rails of many drawers in furniture, a rebound device is often used to achieve automatic opening or closing with damping and silence. Generally, the rebound device mainly includes a spring and a force-receiving block. The spring applies an elastic thrust to the force-receiving block, and the force-receiving block is installed between a fixed sliding rail and a movable sliding rail through a clamping mechanism, providing an elastic thrust when the sliding rail is opened and achieving a damping force when it is closed.

[0003] Generally, the general rebound device cannot well cooperate with the synchronization problem of the movement of the force-receiving block, and when the sliding rail is suddenly pulled externally, it will cause a huge impact on the rebound device and the force-receiving block, and it is easy to cause the connection components of the force-receiving block or the rebound device to break. Therefore, in view of the above problems, we need a rebound device that can smoothly and elastically achieve the automatic opening and damping closing actions of the sliding rail and is resistant to impact and fracture. Summary of the Invention

[0004] The purpose of the present invention is to provide a furniture rebound device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A furniture rebound device, comprising a dialing pin and a rebound device main body. The dialing pin and the rebound device main body are respectively installed on the same-side side walls of a movable slide rail and a fixed slide rail. The movable slide rail is longitudinally slidably clamped on the fixed slide rail. A rebound slider is longitudinally slidably clamped in the rebound device main body. A spring for driving the rebound slider to longitudinally slide is installed at the rear end of the rebound device main body. A hook assembly for buckling with the dialing pin is provided at the front end of the rebound slider. The hook assembly includes a hook slider and a dialing pin stop block. The dialing pin stop block is fixedly installed at the front end of the top of the rebound slider. The hook slider is rotatably installed on the front side of the dialing pin stop block. A linkage notch for vertically inserting the dialing pin is formed by enclosing between the vertically state hook slider and the dialing pin stop block. An extension opening for leaking the linkage notch is provided at the top of the rebound device main body. A sliding groove is longitudinally provided on the inner side wall of the rebound device main body. The sliding groove includes a hook block sliding groove and a pendulum needle sliding groove which are longitudinally communicated with each other. A parallel sliding limit block is fixed on the side wall of the hook slider relative to the sliding groove. The parallel sliding limit block is longitudinally slidably clamped in the hook block sliding groove and keeps the hook slider in a vertical state. The front end of the hook block sliding groove is communicated with a hook block rotation arc groove for the hook slider to rotate forward and retract into the extension opening. A pendulum needle rotation groove is formed on the rear side wall of the rebound slider. A limit pendulum needle is rotatably fixed in the pendulum needle rotation groove. A pendulum needle sliding head is vertically fixed on the swinging end face of the limit pendulum needle. The pendulum needle sliding head is slidably clamped in the pendulum needle sliding groove. A connected loop groove is provided at the rear end of the pendulum needle sliding groove. A pendulum needle clamping block for longitudinally hanging the pendulum needle sliding head is fixed at the center position of the loop groove. An outwardly convex impact force receiving block is fixed on the side wall of the rebound slider. The impact force receiving block is arranged in front of the parallel sliding limit block. The impact force receiving block is slidably clamped in the pendulum needle sliding groove. When the pendulum needle sliding head hangs on the pendulum needle clamping block, an elastic member is arranged at the position of the sliding groove corresponding to the impact force receiving block.

[0007] A further solution: A spring is longitudinally fixed between the inner side surface of the rear end of the rebound device main body and the inner side surface of the rear end of the rebound slider along the sliding direction of the movable slide rail and the fixed slide rail. A spring guide post is inserted into the spring. The rear end of the spring guide post is vertically fixed on the inner side surface of the rear end of the rebound device main body. A guide rod groove for the front end head of the spring guide post to slidably penetrate into is longitudinally provided at the rear end inside the rebound slider. When the pendulum needle sliding head hangs on the pendulum needle clamping block, the spring is in a contracted state.

[0008] A further solution: The front end head of the pendulum needle clamping block is a wedge head parallel to the axis of the pendulum needle sliding groove. A slope for facilitating the upward and backward sliding of the pendulum needle sliding head is provided at the top of the pendulum needle clamping block. A clamping notch longitudinally shrinking towards the pendulum needle sliding groove is provided at the rear end head of the pendulum needle clamping block. A guide sliding opening for guiding the pendulum needle sliding head to slide into the pendulum needle sliding groove is provided at the top of the rear end of the loop groove. A guide landslide for guiding the pendulum needle sliding head to slide back into the pendulum needle sliding groove is provided at the bottom of the rear end of the loop groove.

[0009] Further solution: The elastic member includes an elastic groove edge. The sliding groove is enclosed by side panels connected by two longitudinal groove plates. The elastic groove edge is arranged at the position where the pendulum needle slider impacts the force receiving block when sliding into the pendulum needle sliding groove. When the hook slider rotates towards the inside of the outlet and is received, it abuts against the bottom groove plate of the rebounder body. The elastic groove edge is arranged as a part of one side groove plate that is pressed.

[0010] Further solution: The bottom of the rebounder body is horizontally slidably mounted on the groove plate. The groove plate has an upward opening and is connected left and right. The groove plate is fixed on the side wall of the fixed slide rail. The rear end of the rebounder body is slidably inserted into the insertion plate. The insertion plate is fixed on the side wall of the fixed slide rail and has an opening facing forward. A stud seat is installed at the head end of the rebounder body. A regulating bolt is threadedly inserted into the stud seat. The smooth rod arm on the end side of the regulating bolt is longitudinally rotatably mounted on the shaft rotating frame. The shaft rotating frame is fixed on the side wall of the fixed slide rail on the same side of the groove plate and the insertion plate. A regulating nut is threadedly sleeved on the threaded end of the regulating bolt between the stud seat and the shaft rotating frame. The front and rear end faces of the regulating nut are slidably in contact with the end faces of the shaft rotating frame and the stud seat.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can not only realize the automatic opening and damped closing functions of the movable slide rail and the fixed slide rail, but also when forcibly pulling the movable slide rail and the fixed slide rail, the elastic member can prompt the hook slider to rotate and disengage from the hook block sliding groove, so as to ensure the smooth disengagement of the dialing needle and the hook slider, and will not cause too large impact force on the components of the dialing needle and the hook slider, prevent the fracture and damage of the connecting components, and greatly improve the overall service life and operation stability of the rebounder body.

Detailed implementation manner

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 5, in the embodiment of the present invention, a furniture rebounding device includes a dialing pin 10 and a rebounder main body 3. The dialing pin 10 and the rebounder main body 3 are respectively installed on the same-side side walls of the movable slide rail 1 and the fixed slide rail 2. The movable slide rail 1 is longitudinally slidably clamped on the fixed slide rail 2. A rebounding slider 4 is longitudinally slidably clamped in the rebounder main body 3. A spring 5 for driving the rebounding slider 4 to longitudinally slide is installed at the rear end of the rebounder main body 3. The front end of the rebounding slider 4 is provided with a hook assembly for buckling with the dialing pin 10. The hook assembly includes a hook slider 40 and a dialing pin stop block 43. The dialing pin stop block 43 is fixedly installed at the front end of the top of the rebounding slider 4. The hook slider 40 is rotatably installed on the front side of the dialing pin stop block 43. A linkage notch for the vertical insertion and buckling of the dialing pin 10 is enclosed between the vertically state hook slider 40 and the dialing pin stop block 43. An extension opening 33 for the leakage of the linkage notch is provided at the top of the rebounder main body 3. A sliding groove 31 is longitudinally provided on the inner side wall of the rebounder main body 3. The sliding groove 31 includes a hook block sliding groove 310 and a pendulum needle sliding groove 311 that are longitudinally communicated with each other. A parallel sliding limit block 401 is fixed on the side wall of the hook slider 40 relative to the sliding groove 31. The parallel sliding limit block 401 is longitudinally slidably clamped in the hook block sliding groove 310 and keeps the hook slider 40 in a vertical state. The front end of the hook block sliding groove 310 is communicated with a hook block rotation arc groove 314 for the forward rotation and retraction of the hook slider 40 into the extension opening 33. A pendulum needle rotation groove 42 is provided on the rear side wall of the rebounding slider 4. A limit pendulum needle 41 is rotatably fixed in the pendulum needle rotation groove 42. A pendulum needle sliding head 410 is vertically fixed on the swinging end face of the limit pendulum needle 41. The pendulum needle sliding head 410 is slidably clamped in the pendulum needle sliding groove 311. A loop groove 312 is provided at the rear end of the pendulum needle sliding groove 311. A pendulum needle clamping block 313 for longitudinally hanging the pendulum needle sliding head 410 is fixed at the central position of the loop groove 312. An outwardly convex impact force receiving block 402 is fixed on the side wall of the rebounding slider 4. The impact force receiving block 402 is arranged at the front end of the parallel sliding limit block 401. The impact force receiving block 402 is slidably clamped in the pendulum needle sliding groove 311. When the pendulum needle sliding head 410 hangs on the pendulum needle clamping block 313, an elastic component is arranged at the position of the sliding groove 31 corresponding to the impact force receiving block 402.

[0022] A spring 5 is longitudinally fixed between the inner side surface at the rear end of the ejector body 3 and the inner side surface at the rear end of the ejector slider 4 along the sliding direction of the movable slide rail 1 and the fixed slide rail 2. A spring guide post 50 is inserted into the spring 5. The rear end of the spring guide post 50 is vertically fixed on the inner side surface at the rear end of the ejector body 3. A guide rod groove 44 for the front end head of the spring guide post 50 to slide into is longitudinally formed at the rear end inside the ejector slider 4. When the pendulum needle slider 410 hooks the pendulum needle engaging block 313, the spring 5 is in a contracted state. The provided spring 5 is mainly used to push the ejector slider 4 to slide inside the ejector body 3. When the pendulum needle slider 410 hooks the pendulum needle engaging block 313, the movable slide rail 1 is in a retracted state. The ejector slider 4 stores elastic potential energy in the spring 5 through the pendulum needle slider 410. When the pendulum needle slider 410 disengages from the pendulum needle engaging block 313, the spring 5 releases the elastic potential energy, pushes the ejector slider 4 forward, and thus drives the entire movable slide rail 1 to automatically open.

[0023] The front end head of the pendulum needle engaging block 313 is a wedge-shaped head parallel to the axis of the pendulum needle chute 311. A slope for facilitating the upward and backward sliding of the pendulum needle slider 410 is provided at the top of the pendulum needle engaging block 313. A clamping notch longitudinally retracted towards the pendulum needle chute 311 is provided at the rear end head of the pendulum needle engaging block 313. A guiding slide opening for guiding the pendulum needle slider 410 to slide into the pendulum needle chute 311 is provided at the top of the rear end of the loop groove 312. A guiding slope for guiding the pendulum needle slider 410 to slide back into the pendulum needle chute 311 is provided at the bottom of the rear end of the loop groove 312. When the pendulum needle slider 410 moves to the end of the pendulum needle chute 311, it enters the loop groove 312. First, the pendulum needle slider 410 moves towards the guiding slide opening driven by the slope of the pendulum needle engaging block 313 and moves to the clamping notch under the action of the guiding slide opening. At this time, the spring 5 has a longitudinally forward thrust on the ejector slider 4. Therefore, the pendulum needle slider 410 will be horizontally clamped in the clamping notch. When a backward pressure is applied to the ejector slider 4, the pendulum needle slider 410 falls off from the clamping notch and slides back into the pendulum needle chute 311 along the guiding slope, completing the position limiting action and the ejecting action of the ejector slider 4.

[0024] The elastic component includes an elastic groove edge 32, and the sliding groove 31 is formed by two longitudinal groove plates connecting the side panels of 3. The elastic groove edge 32 is arranged at the position of the impact force block 402 when the swing needle slider 410 slides into the swing needle slide groove 311. During the process of rotating and accommodating the hook slider 40 toward the extension opening 33, it abuts against the bottom groove plate of the rebounder body 3. The elastic groove edge 32 is arranged to abut against a part of the groove plate on one side. The elastic groove edge 32 can be set when the movable slide rail 1 is suddenly pulled, that is, when the needle 10 suddenly wants to break away from the linkage groove surrounded by the needle stopper block 43 and the hook slider 40. At this time, the needle 10 will apply an impact force to the hook slider 40. At this time, the parallel sliding limit block 401 has not moved to the hook block rotation arc groove 314 and cannot rotate. Therefore, the hook slider 40 will be subjected to a large downward impact force, which may easily cause the hook slider 40 or the needle 10 to break. At this time, the force point of the hook slider 40 is at the impact force block 402. The impact force block 402 will exert an impact force on the slot plate of the sliding slot 31. In order to prevent the hook slider 40 or the dial needle 10 from breaking, the slot plate here is set as a compressible and deformable elastic slot edge 32. When the impact force block 402 is subjected to an impact force at this position, the impact force block 402 will press down the elastic slot edge 32, and the elastic slot edge 32 will deform. The impact force block 402 will directly disengage from the swing needle slot 311, and the hook slider 40 will rotate as a whole and be collected into the extension opening 33. The hook slider 40 will no longer block the outward pulling of the dial needle 10, and the hook slider 40 will not be unable to rotate due to excessive impact and cause breakage. When the impact force block 402 needs to be reset, the dial needle 10 is pushed back toward the dial needle stopper 43. When the rebound slider 4 drives 40 to move backward, the impact force block 402 is pulled back and rebounds back into the swing needle slot 311, and the rebound slider 4 returns to a normal state.

[0025] The working principle of the present invention is as follows: During operation, when the movable slide rail 1 and the fixed slide rail 2 are in the closed state, the pendulum needle slider 410 is hooked on the pendulum needle clamping block 313, and the spring 5 is in a contracted state. When the movable slide rail 1 is pulled outwards, the pendulum needle slider 410 is disengaged from the pendulum needle clamping block 313 and returns to the pendulum needle chute 311. The spring 5 releases its elastic potential energy and pushes the rebound slider 4 forward. At this time, the rebound slider 4 slides in the hook block chute 310 through the parallel sliding limit block 401. The hook slider 40 and the needle-pushing block 43 maintain the enclosure state of the linkage notch. When the linkage notch catches the needle-pushing 10, the rebound slider 4 will push the needle-pushing 10 outwards automatically. When the parallel sliding limit block 401 moves to the hook block rotating arc groove 314, the hook slider 40 rotates, the linkage notch opens, and the hook slider 40 no longer blocks the needle-pushing 10. The movable slide rail 1 can continue to open to the maximum position under the action of inertia, and the movable slide rail 1 realizes the automatic open state. When the movable slide rail 1 is pushed inwards to close, when the needle-pushing 10 hits the needle-pushing block 43, the rebound slider 4 slides backwards, and the parallel sliding limit block 401 slides from the hook block rotating arc groove 314 to the hook block chute 310. The hook slider 40 rotates again to enclose the needle-pushing 10 until the pendulum needle slider 410 is re-locked on the pendulum needle clamping block 313 to keep the movable slide rail 1 and the fixed slide rail 2 completely closed. During the closing process, the spring 5 continuously applies force to the rebound slider 4 to achieve the damping closing effect. When the movable slide rail 1 and the fixed slide rail 2 are in the closed state and the movable slide rail 1 is suddenly and violently pulled outwards, at this time, the hook slider 40 will receive a large downward impact force, which may easily cause the fracture of the hook slider 40 or the needle-pushing 10. At this time, the force application point of the hook slider 40 is at the impact force receiving block 402, and the impact force receiving block 402 will apply an impact force to the groove plate of 31. In order to prevent the fracture of the hook slider 40 or the needle-pushing 10, the groove plate here is set as an elastic groove edge 32 that can be compressed and deformed. When the impact force receiving block 402 receives an impact force at this position, the impact force receiving block 402 will press down the elastic groove edge 32, and the elastic groove edge 32 deforms. The impact force receiving block 402 directly disengages from the pendulum needle chute 311, then the whole hook slider 40 will rotate, and the hook slider 40 no longer blocks the outward pull of the needle-pushing 10. The hook slider 40 will not be affected by too large an impact and unable to rotate, resulting in fracture. When the impact force receiving block 402 needs to be reset, the needle-pushing 10 is pushed towards the needle-pushing block 43 again. When the rebound slider 4 drives 40 to move backwards, the impact force receiving block 402 is pulled back and popped up to return to the pendulum needle chute 311, and the rebound slider 4 returns to the normal state. Thus, the present invention can not only realize the automatic opening and damping closing functions of the movable slide rail 1 and the fixed slide rail 2, but also when the movable slide rail 1 and the fixed slide rail 2 are forcibly pulled, the elastic component can prompt the hook slider 40 to rotate and disengage from the hook block chute 310, so as to ensure the smooth disengagement of the needle-pushing 10 and the hook slider 40, and will not cause too large an impact force on the components of the needle-pushing 10 and the hook slider 40, preventing the fracture and damage of the connecting components, and greatly improving the overall service life and operation stability of the rebounder main body 3.

[0026] Example 2

[0027] Please refer to Figure 1 and Figure 6 , the difference between this embodiment and Embodiment 1 is that:

[0028] The bottom of the rebounder body 3 is horizontally slidably mounted on the groove plate 21. The groove plate 21 has an upward opening and is connected left and right. The groove plate 21 is fixed on the side wall of the fixed slide rail 2. The rear end of the rebounder body 3 is slidably inserted into the insertion plate 22. The insertion plate 22 is fixed on the side wall of the fixed slide rail 2 and has an opening facing forward. A stud base 302 is installed at the head end of the rebounder body 3. A regulating bolt 301 is threaded through the stud base 302. The smooth rod arm on the end side of the regulating bolt 301 is longitudinally rotatably mounted on the shaft rotating frame 20. The shaft rotating frame 20 is fixed on the side wall of the fixed slide rail 2 on the same side of the groove plate 21 and the insertion plate 22. A regulating nut 30 is threadedly sleeved on the threaded end of the regulating bolt 301 between the stud base 302 and the shaft rotating frame 20. The front and rear end faces of the regulating nut 30 are in sliding contact with the end faces of the shaft rotating frame 20 and the stud base 302. When the regulating nut 30 rotates, the length of the regulating bolt 301 extending into the stud base 302 changes, so that the overall longitudinal position of the rebounder body 3 changes. The rebounder body 3 is vertically supported by the groove plate 21 and the insertion plate 22. The regulating nut 30 is mainly used to facilitate the adjustment of the longitudinal installation position of the rebounder body 3, so as to facilitate the installation and cooperation of the dialing pin 10 and the linkage notch.
