Description

Technical Field

[0001] The utility model relates to the technical field of synchronous rebound mechanisms, in particular to a synchronous rebound mechanism for rapid synchronous unlocking and resetting. Background Art

[0002] The press-rebound mechanism is often used as a functional accessory for hidden guide rails. It stores energy when closed and leaves space for pressing to unlock. By pressing the drawer, the drawer and other pull-out furniture are unlocked and rebounded, making the pull-out furniture automatically pop open. It is very convenient to use and improves safety.

[0003] However, the above-mentioned pressing rebound mechanism has the following shortcomings in practical applications:

[0004] 1) When the energy storage is closed, the synchronous component of the press-rebound mechanism does not slide to the specified limited position without being subjected to other external forces, resulting in failure of the press-rebound mechanism, which seriously affects the normal use of the drawer.

[0005] 2) The connection between the push-and-rebound mechanism and the push-and-rebound mechanism is unstable, resulting in poor synchronization of the push-and-rebound mechanisms on both sides of the drawer, and the mechanism is prone to jamming, which seriously affects the smoothness and stability of the drawer operation. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a synchronous rebound mechanism for rapid synchronous unlocking and resetting, which has a simple structure and effectively avoids failure of the mechanism due to the unlocking structure not being in place during natural closing, thereby improving the stability of the structure, ensuring the synchronous locking and unlocking effect, and ensuring the normal use of the product.

[0007] The inventive objective of the utility model is achieved as follows: a synchronous rebound mechanism with a synchronous unlocking function, comprising a rebound component arranged on guide rails on both sides of the drawer, the rebound component being connected with a synchronous linkage component for synchronous locking and unlocking, wherein the rebound component comprises a base installed on a fixed rail, the base being provided with a rebound sliding component that can slide in for energy storage and be pressed to slide out for pressure release, and a rebound sliding groove for locking or unlocking the rebound sliding component, the rebound sliding component being provided with a setting pin, the rebound sliding groove being provided with a limiting position for the setting pin to slide and generate an effective distance for pressing and rebounding, the base being detachably provided with a limiting spring for pulling the synchronous linkage component to a limiting position when not subject to external force during locking, and the two elastic ends of the limiting spring being respectively buckled on the base and the synchronous linkage component.

[0008] According to the above optimization, the synchronous linkage component includes a synchronous slider and a linkage rod portion, and the linkage rod portion is respectively linked and connected to the synchronous slider. The synchronous slider is pushed up and down on the base by the rebound sliding group and the pull of the needle, and the end of the synchronous slider is matched and clamped with the limit spring.

[0009] According to the above optimization, the synchronous slider is provided with a card position, a limiting convex edge, a synchronous linkage connection position and a pushing connection portion. The card position is provided at the top of the synchronous slider and is clamped with the limiting spring. The limiting convex edge is provided on the inner side of the synchronous slider and can form a limiting position for locking the setting pin with the rebound sliding groove. The limiting convex edge is provided with a buckling groove for buckling with the setting pin when rebounding and unlocking. The pushing connection portion is provided at the bottom of the synchronous slider and can be connected with the rebound sliding assembly when locked.

[0010] According to the above optimization, the rebound sliding assembly includes a rebound slider, an energy storage spring, and a shifting pin. The rebound slider is slidably connected to the base and is buckled or separated from the movable rail. The two elastic ends of the energy storage spring are respectively buckled on the rebound slider and the base. The shifting pin is rotatably connected to the top of the rebound slider. The rebound slider is integrally formed with a pushing rod for pushing the synchronous linkage component.

[0011] According to the above optimization, the installation position of the energy storage spring is consistent with the radial direction of the sliding of the synchronous linkage component.

[0012] According to the above optimization, the push rod portion is located on the outside of the rebound slider and is provided with a buckling portion for buckling with the energy storage spring.

[0014] The advantages of the utility model are:

[0015] 1) By adding a limit spring, the synchronous slider of the synchronous linkage component can be pulled to the specified limit position, thereby ensuring that the mechanism will not fail due to the synchronous linkage component not being in place when it is naturally closed.

[0022] The present utility model will be further described below with reference to the accompanying drawings.

[0023] According to the attached Figures 1 to 5 As shown, the synchronous rebound mechanism for rapid synchronous unlocking and resetting of the present utility model includes a rebound component provided on the guide rails on both sides of the drawer, and the rebound component is connected with a synchronous linkage component 6 for synchronous locking and unlocking. Among them, the rebound component includes a base 1 for installing on the fixed rail, the base 1 is provided with a rebound sliding component 2 that can slide in for energy storage and slide out for pressure release, and a rebound sliding groove 3 for locking or unlocking the rebound sliding component 2. The rebound sliding component 2 is installed with a dialing pin 4, and the rebound sliding groove 3 is provided with a limit position 5 for the dialing pin 4 to slide and generate an effective distance for pressing and rebounding. The base 1 is detachably installed with a limit spring 7 for pulling the synchronous linkage component 6 to the limit position 5 without external force during locking, and the two elastic ends of the limit spring 7 are respectively buckled on the base 1 and the synchronous linkage component 6.

[0024] By adding the limit spring 7, it can pull the synchronous linkage component 6 to the specified limit position 5, so as to ensure that the mechanism will not fail due to the non-arrival of the synchronous linkage component 6 when naturally closing. When unlocked by external force, the synchronous slider 61 of the synchronous linkage component 6 is synchronously unlocked and then quickly returns to its original position under the action of the limit spring 7 to wait for the next locking and unlocking operation.

[0025] Referring to Figures 1 to 5 As shown, for further refinement, the synchronous linkage component 6 includes a synchronous slider 61 and a linkage rod part. The linkage rod parts are respectively linked and connected to the synchronous slider 61. The synchronous slider 61 moves up and down on the base 1 by being pushed by the rebound sliding group and pulled by the dialing pin 4, and the end of the synchronous slider 61 is fitted and clamped with the limit spring 7.

[0026] Among them, the synchronization slider 61 is provided with a clamping position 62, a limiting flange portion 63, a synchronous linkage connection position 64, and a pushing connection portion 65. The clamping position 62 is provided at the top of the synchronization slider 61 and is clamped with the limiting spring 7. The limiting flange portion 63 is provided inside the synchronization slider 61 and can form a limiting position 5 for locking the dial pin 4 with the rebound sliding groove 3. The limiting flange portion 63 is provided with a clamping groove 66 for clamping with the dial pin 4 when unlocking by rebound. The pushing connection portion 65 is provided at the bottom of the synchronization slider 61 and can be connected to the rebound sliding assembly 2 when locking.

[0027] That is, when the drawer is closed, the rebound sliding assembly 2 is pushed inward along the base 1. When it is pushed to a specified position, the rebound sliding assembly 2 is connected to the pushing connection portion 65 of the synchronization slider 61 and pushes the synchronization slider 61 to move upward. At the same time, under the linkage action of the synchronous linkage connection position 64, the linkage rod portion is driven to rotate, so as to synchronously drive the rebound components on the other side to enter the locking action synchronously. When the dial pin 4 moves to the top along the rebound sliding groove 3 and is not affected by other positions, under the elastic reset force of the rebound sliding assembly 2, the dial pin 4 falls back to the limiting position 5 of the rebound sliding groove 3. At this time, the synchronous sliding block is also pulled to the limiting position 5 under the elastic action of the limiting spring 7. In this way, with the structural cooperation between the synchronous sliding block and the rebound sliding groove 3, the dial pin 4 is locked in the limited position, and the normal locking state of the mechanism is realized.

[0028] When the drawer is opened, the drawer is pressed, and the rebound sliding assembly 2 drives the dial pin 4 to move inward along the other side of the rebound sliding groove 3 to move away from the limiting position 5. Subsequently, the dial pin 4 is pulled downward under the action of the reset elastic force of the rebound sliding assembly 2 and is clamped on the clamping groove 66 of the synchronous sliding block, so that the rebound sliding assembly 2 is pulled outward and the synchronous slider 61 drives the linkage rod portion to rotate, realizing the synchronous unlocking of the rebound components on both sides. After synchronous unlocking, the synchronous slider 61 quickly returns to its original position under the reset elastic action of the limiting spring 7 to wait for the next locking and unlocking.

[0029] Refer to Figures 1 to 5 As shown, in further detail, the rebound sliding assembly 2 includes a rebound slider 21, a storage spring 22, and a dial pin 4. The rebound slider 21 is slidably connected to the base 1 while being clamped or separated from the movable rail. The two elastic ends of the storage spring 22 are respectively clamped on the rebound slider 21 and the base 1. The dial pin 4 is rotatably connected to the top of the rebound slider 21. The rebound slider 21 is integrally formed with a pushing rod portion 23 for pushing the synchronous linkage member 6.

[0030] Among them, the pushing rod portion 23 is located outside the rebound slider 21 and is provided with a clamping portion 24 for clamping with the storage spring 22.

[0031] Furthermore, the installation position of the energy storage spring 22 is consistent with the radial direction of the sliding of the synchronous linkage component 6 .

[0032] Through the structural coordination of the rebound sliding assembly 2, the rebound sliding groove 3 and the synchronous linkage component 6, the connection between the pushing and pressing rebound actions is stable, which can improve the synchronization and stability of the rebound components on both sides of the drawer, ensure synchronous locking and unlocking, and ensure the quality of product use.

[0033] Reference Figures 1 to 5 As shown, in further detail, the rebound slider 21 is provided with a buffer toggle block 25 with a silent effect, the buffer toggle block 25 is rotatably connected to the rebound slider 21 and forms a snap hook with the rebound slider 21, and the snap hook is snapped or disengaged with the movable rail when the rebound slider 21 slides.

[0034] Under the action of the buffer toggle block 25, it can be toggled to connect to the rebound slider 21, ensuring smooth buckling or disengagement with the movable rail, ensuring the normal operation of the rebound mechanism, and having a buffering and silencing effect.

[0035] The above specific embodiments are only specific implementation methods with better effects of the utility model. Any structure that is the same or equivalent to the synchronous rebound mechanism for rapid synchronous unlocking and resetting of the utility model is within the protection scope of the utility model.
