Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buffer bounce synchronizer, in particular to a buffer bounce synchronizer with load and strong push protection function. BACKGROUND

[0002] The function accessories of the commonly used hidden slide rail have a press bounce synchronizer, which is arranged on the hidden slide rail on the left and right sides of the drawer, and a synchronous running component is arranged between the press bounce synchronizer and the press bounce synchronizer. The press bounce synchronizer is used to store energy when the hidden slide rail is closed, and a space for pressing unlocking is left. By pressing the drawer, the drawer and the pull furniture are unlocked and bounced, the pull furniture is automatically bounced open, which is very convenient to use, and the use safety is improved.

[0003] However, after the traditional press bounce synchronizer is installed on the slide rail, when the drawer is pressed and bounced out and then pressed back or thrown back, there is no damping, the drawer directly collides with the cabinet, generates a large noise, and even damages the components, reduces the use stability, and seriously affects the service life of the product.

[0004] In order to reduce the generation of noise, the press bounce synchronizer is generally provided with a buffer damper. When the slide rail is closed, the pressing block of the press bounce synchronizer is engaged with the fork of the movable rail, and under the damping action of the buffer damper, the slide rail has a buffering effect when it is closed.

[0005] Therefore, after the buffer bounce synchronizer is installed on the slide rail, it can be used as a bounce slide rail or a damping slide rail during use. That is, the drawer can be pressed and bounced out or directly pulled out. If it is used as a bounce slide rail, under the action of the buffer bounce synchronizer, the drawer can be directly thrown back when it is pushed back, and the damping is provided when it is returned.

[0006] However, the above-mentioned buffer press bounce synchronizer cannot play the role of resistance under the condition of load, especially when the load is 20kg or more, the press bounce synchronizer is bounced out, the resistance value cannot play a role, and the drawer will be bounced out immediately, so that the drawer cannot be normally closed, and there is a safety hazard.

[0033] According to the above description, the present application has the following advantages.

[0034] Figures 1 to 15 ​​​​​​​​​​As shown, the buffer rebound synchronization device with load-bearing strong push protection function of the present application comprises slide rails arranged on the left and right sides of the drawer and buffer rebound components, and synchronization running components are installed between the buffer rebound components. The buffer rebound component comprises a rebound housing 1, an energy storage sliding module 2 and a push block 3. The rebound housing 1 is installed on the fixed rail of the slide rail, the positioning end of the energy storage sliding module 2 is elastically connected to the rebound housing 1, and the push block 3 is buckled or separated from the movable rail of the slide rail along with the opening and closing of the drawer, while pushing the movable end of the energy storage sliding module 2 to slide on the rebound housing 1. Among them, the rebound housing 1 is provided with a load protection component for completing energy storage locking under the condition of strong push of the drawer under load. The load protection component comprises a limiting piece 4 for limiting the inward movement of the energy storage sliding module 2 and a deceleration piece 5 for slowing down the inward movement of the push block 3. The limiting piece 4 is slidingly connected to the rear end of the rebound housing 1, the positioning end of the deceleration piece 5 is shaft-connected to the rebound housing 1, the swing end of the deceleration piece 5 is connected to the limiting piece 4, and the deceleration elastic end of the deceleration piece 5 is connected to the inwardly moving push block 3.

[0035] Through the structural cooperation of the limiting piece 4 and the deceleration piece 5 of the load protection component, the structure is compact, and the buffer rebound component can be quickly pushed back into the cabinet under the condition of load, especially 20KG or more pressing and popping out, when the drawer is closed violently, even if the closing force is greater than the deceleration force value of the damping, the drawer quickly hits the cabinet and rebounds, so that the drawer door plate and the cabinet maintain a pressing distance, instead of popping out immediately, ensuring normal use of the product and improving use safety.

[0036] Reference Figures 1 to 15 As shown, further refinement, the energy storage sliding module 2 comprises an energy storage sliding block 21, a tension spring 22 and a transmission member 23. The positioning elastic end of the tension spring 22 is clamped on the rebound housing 1, and the movable elastic end of the tension spring 22 is clamped on the energy storage sliding block 21. The energy storage sliding block 21 slides forward and backward on the rebound housing 1 under the pushing of the push block 3 or the elastic action of the tension spring 22. One end of the transmission member 23 is positioned and shaft-connected to the rear end of the energy storage sliding block 21, and the other end of the transmission member 23 is provided with a push pin 24 which moves vertically backward at the rear end of the rebound housing 1 when the drawer is strongly pushed under load, and falls back under the elastic action of the tension spring 22 and enters the locking state to be connected with the synchronization running component.

[0037] Moreover, the rear end of the rebound shell 1 is provided with a transmission straight slot 11 for directional reciprocating movement of the transmission member 23, a transmission locking slot 12 for entering the locking state of the transmission member 23, and a reset inclined slot 13 for resetting the push pin 24 and pushing the synchronous operation component. The transmission straight slot 11, the transmission locking slot 12, and the reset inclined slot 13 are connected in sequence to form a transmission member 23 circulating movement path, and the intersection of the transmission straight slot 11 and the transmission locking slot 12 is provided with a load limit slot 14 for the limiting member 4 to slide forward and backward when the drawer is heavily pushed, so that the push pin 24 vertically moves backward and contacts the limiting member 4 after falling back and moving to the transmission locking slot 12.

[0038] In addition, the limiting member 4 is provided with a protrusion 41 for leading the push pin 24 to vertically move backward, fall back, and move to the transmission locking slot 12. The protrusion 41 is arranged at the front end of the limiting member 4, so that the load limit slot 14, the transmission locking slot 12, and the reset inclined slot 13 form a Y-shaped guide slot for directional backward movement, rebound locking, and forward movement of the push pin 24.

[0039] The speed reduction member 5 includes a connecting part 51 and a spring arm 52. The positioning end of the connecting part 51 is connected to the rebound shell 1, the swing end of the connecting part 51 is connected to the limiting member 4, and the spring arm 52 is integrally formed on the connecting part 51 and elastically connected to the inner wall of the rebound shell 1 and the push block 3.

[0040] Furthermore, the energy storage slider 21 is provided with a spring stopper 25 and a push rod 26. The spring stopper 25 is elastically connected to the energy storage slider 21, and the bottom surface of the spring stopper 25 is provided with a positioning protrusion for being driven by the push block 3 to slide backward on the rebound shell 1, so that the spring stopper 25 is compressed and then separated from the push block 3. The push rod 26 is arranged at the rear end of the energy storage slider 21 and moves backward to push the synchronous operation component.

[0041] In addition, the synchronous operation component includes a synchronous rod 6, a synchronous swing rod 7, and a synchronous slider 8. The synchronous slider 8 slides forward and backward in the rebound shell 1, the energy storage slider 21 is provided with the push pin 24 and the push rod 26 for pushing the synchronous slider 8 to move forward or backward, and the two ends of the synchronous rod 6 are respectively inserted into the upper swing end of the synchronous swing rod 7, and the lower swing end of the synchronous swing rod 7 is installed on the synchronous slider 8.

[0042] The working principle of quickly pushing back after bearing 20KG or more compression and rebound:

[0043] When the drawer is closed, the movable rail of the slide rail is buckled with the push block 3, and the push block 3 drives the energy storage slider 21 to move backward along with the movable rail closing. During this period, the positioning protrusion of the compressed elastic block 25 also slides linearly backward on the rebound shell. At the same time, the transmission member 23 slides backward on the transmission straight slot 11 along with the energy storage slider 21, and the push rod 26 pushes the synchronous sliding block to slide backward, thereby driving the synchronous swing rod 7 to drive the synchronous rod 6 to act.

[0044] When the push block 3 is pushed inward and is about to be disengaged from the elastic block 25, the push pin 24 is operated to the protrusion 41 of the limiting member 4. At this time, the tension spring 22 that presses the buffer rebound component is energized.

[0045] Subsequently, along with the movable rail moving backward, the push block 3 is disengaged from the elastic block 25, and the push block 3 is connected with the elastic arm 52 of the deceleration member 5, and the damping starts to normally pull back to the damping limit position. At this time, the push pin 24 is blocked by the limiting member 4, and the limiting member 4 is pushed by the elastic arm 52 of the deceleration member 5, so that the limiting member 4 can block the push pin 24 from reaching the rebound locking state. At this time, the buffer rebound component of the structure reaches the limit position of the soft closing under no load or light load.

[0046] When the drawer is loaded with 20 kg or more, it is quickly pushed back, or it is pushed inward after the damping force value reaches the limit position, which is the limit position of the violent test. Since the damping cannot play a role in deceleration, the push block 3 drives the elastic arm 52 of the deceleration member 5 to swing backward, thereby driving the limiting member 4 to slide backward and give the push pin 24 of the transmission member 23 a space. Then, the push pin 24 is operated along with the energy storage slider 21 to vertically move backward in the load limit slot 14 for a distance. Subsequently, since the push block 3 is against the elastic arm 52 and has no space to continue to push inward, the buffer rebound component of the structure starts to fall forward to the transmission upper locking slot 12 under the elastic action of the return spring 22, and is connected with the synchronous sliding block. In this way, the buffer rebound component enters the rebound locking state.

[0047] When the drawer is pressed to open, the energy storage slider 21 moves forward along with the push block 3 under the rebound force of the return spring 22, and drives the push block 3 to quickly pop out. During this period, the push pin 24 of the transmission member 23 moves forward along with the return inclined slot 13 and pushes the synchronous sliding block to move forward, so as to drive the synchronous rod 6 to rotate and realize the synchronous unlocking and pop-out of the buffer rebound components on the left and right sides.

[0048] The second embodiment (schematic diagram) of the structure is different from the above structure in that the deceleration member 5 comprises a connecting part 51 and a deceleration spring. The positioning end shaft of the connecting part 51 is connected to the rebound shell 1, the swing end of the connecting part 51 is connected to the limiting member 4, one end of the deceleration spring is elastically connected to the push block 3, and the other end of the deceleration spring elastically acts on the connecting part 51 or the limiting member 4.

[0049] The damping spring is used to replace the elastic arm 52, and the buffering and rebounding synchronous device with the bearing and strong pushing protection function can meet the requirements that the buffering and rebounding component can be quickly pushed back into the cabinet under the condition of bearing, especially after being pressed out by 20 kg or more, when the drawer is suddenly closed, even if the force of the sudden closing is greater than the damping deceleration force value, the drawer quickly hits the cabinet and rebounds, the drawer plate and the cabinet maintain the pressing distance, instead of being immediately popped out, which ensures the normal use of the product and improves the use safety.

[0050] The above specific embodiments are only preferred specific embodiments of the buffering and rebounding synchronous device with the bearing and strong pushing protection function, and any structure identical or equivalent to the buffering and rebounding synchronous device with the bearing and strong pushing protection function is within the protection scope of the buffering and rebounding synchronous device with the bearing and strong pushing protection function.
