Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buffer bounce synchronizer, in particular to a load bearing strong push protection device for buffer bounce synchronizer. 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 parts, 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 of the slide 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 return is damped.

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

[0007] The present application aims to overcome the shortcomings of the prior art, and provides a load bearing strong push protection device for buffer bounce synchronizer, which is compact, stable and reliable, and can prevent the drawer from bouncing out immediately after being pressed and bounced out under the condition of bearing load, especially when the load is 20kg or more, and can provide a safe pressing distance between the drawer and the cabinet, thereby improving the use safety.

[0008] The application aims to provide a load-bearing strong-push protection device for a buffer bounce synchronizer.

[0009] According to the above optimization, the rebound housing is provided with a connecting shaft for rotation of the deceleration gear, and the deceleration gear is mounted on the connecting shaft.

[0010] According to the above optimization, the elastic deceleration arm is provided with an inclined surface for sliding friction connection with the deceleration gear.

[0011] According to the above optimization, the buffer bounce component is provided with a synchronous operation component between the buffer bounce components, the synchronous operation component comprising a synchronous sliding block, a synchronous transmission member, and a synchronous connecting rod, both ends of the synchronous connecting rod being respectively inserted with the synchronous transmission member, the synchronous sliding block being slid in and out on the rebound housing under the pushing action of the energy storage sliding module, the synchronous transmission member being transmission-connected on the synchronous sliding block and being swung in and out to drive the synchronous connecting rod to rotate,

[0012] The rebound housing is provided with a torsion spring for pushing the synchronous sliding block back to a closed preset position under pressing, the torsion spring being positioned and mounted on the rebound housing, one elastic end of the torsion spring being connected to the rebound housing, and the other elastic end of the torsion spring being connected to the synchronous sliding block.

[0013] According to the above optimization, the energy storage sliding module comprises an energy storage sliding block, a tension spring, a transmission member, and an elastic stopper, the energy storage sliding block being moved inwards on the rebound housing under the pushing of the pushing block while pushing the synchronous sliding block to move inwards, one elastic end of the tension spring being mounted on the rebound housing, the other elastic end of the tension spring being elastically acted on the energy storage sliding block to make the energy storage sliding block move outwards on the rebound housing, the positioning end of the transmission member being connected to the energy storage sliding block, the swinging end of the transmission member being pushed to move the synchronous sliding block outwards along with the movement of the energy storage sliding block, and the elastic stopper being telescopically connected to the energy storage sliding block.

[0014] The elastic stop is provided with a guide post, and the rebound housing is provided with a step for the guide post to slide directionally and cyclically as the energy storage slider moves. A positioning slot is formed between the end of the step and the rebound housing for the guide post to stop so that the tension spring is in a stretched state, the energy storage slider is kept fixed, and the elastic stop is compressed to separate from the toggle block.

[0015] Based on the above optimization, the swing end of the transmission component is equipped with a linkage pin that moves vertically inward along the rebound housing when pushed by a load, falls back under the elastic reaction force of the tension spring, and is guided into a locked state by the reduction gear. At the same time, it is connected to the synchronization slider of the synchronization component.

[0016] Based on the above optimization, the rebound shell is provided with a Y-shaped guide groove for the linkage pin to slide inward in a directional manner, lock in a directional manner as it moves with the energy storage slider, and slide outward in a rebound reset manner. The Y-shaped guide groove is located at the rear end of the rebound shell.

[0017] The advantages of this invention are: through the structural cooperation of the reduction gear of the load protection component and the elastic limit component, the structure is compact, and the buffer rebound component can quickly push back into the cabinet after being pressed out under load, especially 20KG or more. When the drawer is slammed shut, even if the force of the slamming is greater than the damping deceleration force, the drawer will quickly hit the cabinet and then rebound, keeping the drawer door panel at the pressing distance from the cabinet instead of popping out immediately, ensuring normal use of the product and improving safety.

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] According to the Figures 1 to 17The load bearing strong push protection device for the buffer bounce synchronizer of the present application comprises a buffer bounce component arranged on a slide rail. The slide rail is provided with a damper, and the slide rail has a fixed rail, a middle rail and a movable rail connected in sequence. The fixed rail is arranged on the left and right sides of the cabinet body, and the movable rail is arranged on the left and right sides of the corresponding drawer. The buffer bounce component comprises a bounce housing 1 arranged on the fixed rail of the slide rail, an energy storage sliding module 2 having an energy storage function, and a push block 3 coupled with or separated from the movable rail of the slide rail during opening and closing. The bounce housing 1 is provided with a load protection component for enabling the energy storage sliding module 2 to complete bounce deceleration and energy storage locking under the condition of strong push load. The load protection component comprises a deceleration gear 4 for guiding the energy storage sliding module 2 to move to the locking direction during bounce movement of the energy storage sliding module 2, and an elastic limiting assembly 5 for limiting the rotation position of the deceleration gear 4. The elastic limiting assembly 5 is arranged on the bounce housing 1, and the deceleration gear 4 is rotationally connected to the bounce housing 1 and slidably connected to the elastic limiting assembly 5 under the action of the strong bounce force of the energy storage sliding module 2.

[0037] Through the structural cooperation of the deceleration gear 4 and the elastic limiting assembly 5 of the load protection component, the structure is compact, and the buffer bounce 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 of the damper, the drawer quickly hits the cabinet and bounces back, so that the drawer door plate and the cabinet maintain a pressing distance, rather than popping out immediately, ensuring normal use of the product and improving use safety.

[0038] Referring to Figures 1 to 7 Further refinement, the bounce housing 1 is provided with a connecting shaft for rotation of the deceleration gear 4, and the deceleration gear 4 is arranged on the connecting shaft.

[0039] In addition, the elastic limiting assembly 5 comprises at least one elastic deceleration arm 51, which surrounds the connecting shaft and is arranged on the bounce housing 1. Moreover, the elastic deceleration arm 51 is provided with an inclined surface 52 for slidably and frictionally connecting with the deceleration gear 4.

[0040] That is, when the drawer load is 20KG or more, and the drawer is closed violently, even if the closing force is greater than the deceleration force of the damper, during the process of the drawer quickly hitting the cabinet and bouncing back, the energy storage sliding module 2 moves inward with the push block 3 and touches the deceleration gear 4, and then the energy storage sliding module 2 falls outward along the tooth edge of the deceleration gear 4 and moves to the locking position during the bounce. At this time, the energy storage sliding module 2 can rotate the deceleration gear 4, so that the bottom surface of the corresponding tooth of the deceleration gear 4 and the inclined surface 52 of the elastic deceleration arm 51 slide and frictionally connect, effectively exerting a deceleration effect, so that the drawer does not pop out immediately after hitting the cabinet, improving use safety.

[0041] Referring toFigures 1 to 17 As shown in the diagram, further details are provided, with a synchronous operation component 6 between the buffer rebound components. The synchronous operation component 6 includes a synchronous slider 61, a synchronous transmission component 62, and a synchronous connecting rod 63. The synchronous transmission component 62 is inserted into both ends of the synchronous connecting rod 63. The synchronous slider 61 slides inward and outward on the rebound shell 1 under the pushing action of the energy storage sliding module 2. The synchronous transmission component 62 is drivenly connected to the synchronous slider 61 and swings inward and outward as the synchronous slider 61 slides, thereby driving the synchronous connecting rod 63 to rotate.

[0042] The rebound housing 1 is provided with a torsion spring 7 for pushing the synchronous slider 61 back to the closed preset position when pressed. The torsion spring 7 is positioned and installed on the rebound housing 1. One elastic end of the torsion spring 7 is connected to the rebound housing 1, and the other elastic end of the torsion spring 7 is connected to the synchronous slider 61.

[0043] By adding a torsion spring 7, the function of which is to prevent the synchronous slider 61 from exceeding the preset position when the drawer is pressed. (See attached image) Figure 10 and attached Figure 11 The position of the synchronizer slider 61 shown is the preset position. This preset position is where the linkage pin 10 of the transmission component 23 of the energy storage sliding module 2 enters and connects to the rear end of the synchronizer slider 61. When the synchronizer slider 61 exceeds the preset position, the elastic force of the torsion spring 7 pushes the synchronizer slider 61 back to the preset position, improving the stability of the structure and ensuring the rebound effect of the buffer rebound component.

[0044] Reference Figures 1 to 17 As shown in the diagram, further detailed, the energy storage sliding module 2 includes an energy storage slider 21, a tension spring 22, a transmission component 23, and an elastic stop 24. The energy storage slider 21 moves inward under the actuation of the actuating block 3, simultaneously pushing the synchronous slider 61 inward on the rebound housing 1. One elastic end of the tension spring 22 is mounted on the rebound housing 1, while the other elastic end of the tension spring 22 acts elastically on the energy storage slider 21, causing the energy storage slider 21 to move outward on the rebound housing 1. The positioning end of the transmission component 23 is connected to the energy storage slider 21, and the swinging end of the transmission component 23 moves with the energy storage slider 21 to push the synchronous slider 61 outward. The elastic stop 24 is telescopically connected to the energy storage slider 21.

[0045] The elastic block 24 is provided with a guide post 25, and the rebound housing 1 is provided with a step 8 for the guide post 25 to move and slide directionally and cyclically with the energy storage slider 21. A positioning slot 9 is formed between the end of the step 8 and the rebound housing 1 for the guide post 25 to stop so that the tension spring 22 is in a stretched state, the energy storage slider 21 is kept fixed, and the elastic block 24 is compressed to separate from the toggle block 3.

[0046] In the optimization scheme, the swing end of the transmission member 23 is provided with a connecting pin 10 which is vertically moved inward along the rebound shell 1 under the load thrust, and is guided by the elastic reaction force of the tension spring 22 to fall back and enter the locking state, and is connected with the synchronous slider 61 of the synchronous component.

[0047] In addition, the rebound shell 1 is provided with a Y-shaped guide groove 11 for the connecting pin 10 to move inwardly, fall back and lock, and rebound and slide outwardly when the energy storage slider 21 moves.

[0048] In the optimization scheme, the Y-shaped guide groove 11 of the structure includes a transmission straight groove position 111 for directional reciprocating movement of the transmission member 23, a locking groove position 112 for the transmission member 23 to enter the locking state, and a reset inclined groove position 113 for the connecting pin 10 to reset and drive the synchronous operation component 6, the transmission straight groove position 111, the locking groove position 112 and the reset inclined groove position 113 are connected in sequence to form a circulating movement path of the connecting pin 10 of the transmission member 23, and the intersection of the transmission straight groove position 111 and the locking groove position 112 is provided with a load limit groove position 114 for the connecting pin 10 to vertically move inwardly to collide with the reduction gear 4 and then fall back and move to the locking groove position 112 when the drawer is heavily thrust.

[0049] The working principle of the drawer closing test of 20kg or more:

[0050] 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 inwardly with the movable rail closed. During this period, the guide column 25 of the compressed elastic stop block 24 also slides linearly inwardly on the rebound shell. At the same time, the transmission member 23 slides inwardly on the transmission straight groove position 111 with the energy storage slider 21, and pushes the synchronous slider to slide inwardly, thereby driving the synchronous connecting rod 63 to actuate the synchronous transmission member 62.

[0051] When the push block 3 is pushed inwardly and is about to be disengaged from the elastic stop block 24, the guide column 25 runs to the positioning groove of the step 8. At this time, the tension spring 22 is in a stretched state to complete energy storage.

[0052] Subsequently, as the moving rail moves inward, since the toggle block 3 has the first stage position 31, the inclined surface 32, and the second stage position 33, when the first stage position 31 of the toggle block 3 is disengaged from the elastic stopper 24, the damping starts to work to pull the toggle block 3 back, and the connecting pin 10 is about to enter the teeth of the speed reducer 4. The damping continues to pull the toggle block 3 inward, the elastic stopper 24 is gradually compressed into the energy storage slider 21 along the inclined surface 32 of the toggle block 3, and the guide column 25 is in a free state. Under the elastic action of the tension spring 22, the connecting pin 10 slides upward into the upper locking groove 112. At this time, the speed reducer 4 starts to work, and under the action of friction reduction, the speed of the connecting pin 10 is reduced. At this time, the buffer rebound part of the structure has entered the upper locking groove 112 under the condition of no load or less than 20KG load.

[0053] When the load is 20KG or more, it is quickly pushed back to make the guide column 25 in a free state, or after the damping force reaches the limit, it is pushed inward to the limit position of the violent test; since the damping cannot slow down, the toggle block 33 pushes the energy storage slider 21 to continue to move inward; the inclined surface 32 of the toggle block 3 pushes the elastic stopper 24 to compress into the energy storage slider 21, the guide column 25 is in a free state, and the elastic force of the tension spring 22 pulls the energy storage slider 21 to the reset direction; under the action of the speed reducer 4, the connecting pin 10 makes the elastic stopper 24 from the inclined surface 32 of the toggle block 3 to the second stage position 33 of the toggle block 3, and the connecting pin 10 will not reach the upper locking groove 112 first; at this time, the toggle block 33 continues to apply force to the stopper 24 to push inward, so that the connecting pin 10 enters the load limit groove 114, and during this period, the drawer panel has hit the cabinet side plate, and after there is no force to push inward, the connecting pin 10 is slowly pulled to the upper locking groove 112 under the elastic action of the tension spring 22. Effectively avoid the phenomenon that the drawer is immediately popped out after the heavy load is pressed and pushed back into the cabinet, and the stress cannot be immediately triggered by the rebound of the resistance value.

[0054] When the drawer is pressed to open, the energy storage slider 21 moves outward under the rebound force of the tension spring 22, and is connected with the toggle block 3, and drives the toggle block 3 to pop out. During this period, the connecting pin 10 of the transmission part 23 moves outward along the reset inclined groove 113 and pushes the synchronous sliding block outward to rotate the synchronous connecting rod 63 to realize the synchronous unlocking and popping out of the buffer rebound parts on the left and right sides.

[0055] The above specific embodiments are only preferred specific embodiments of the present application, and any structure identical or equivalent to the buffer rebound synchronizer used by the load-bearing strong push protection device is within the protection scope of the present application.
