When the structure is pressed to open, the elasticity of the third elastic element must be overcome so that the push element can slide open along the track of the heart-shaped slide groove. Since the third elastic element has a large elasticity, the user needs to apply the same force when pressing, which results in the user having to use a larger force to press open the furniture. At the same time, when both opening and closing require the same force, the user must also use a larger force to reset the press-rebound mechanism to close the furniture, which affects the user experience and causes inconvenience to the user. In addition, the pressing position between the press-rebound device and the movable part of the furniture cannot be adjusted, which cannot meet the user's needs. The two are prone to damage due to the generation of interaction force when pressed. Therefore, further improvement is necessary. Summary of the invention

[0012] A connecting part is fixedly arranged on the movable slide rail, and the movable part is rotatably or swingably arranged on the connecting part; the press-rebound device at least includes a rebound bracket, a push piece, a sliding piece, a pressing elastic piece and a lever assembly; wherein the rebound bracket is fixedly arranged on the fixed slide rail, and a heart-shaped slide groove is arranged on it, a sliding part is arranged on the push piece, and the sliding part is used to position and / or slide along the trajectory of the heart-shaped slide groove in a sequential direction, the sliding piece is slidably arranged on the push piece, one end of the pressing elastic piece elastically acts on the rebound bracket, and the other end elastically acts on the push piece or the sliding piece 22, and the lever assembly is cooperatively connected with the push piece and / or the sliding piece.

[0013] The movable slide rail slides on the fixed slide rail through the action of a tool or manual operation, and when sliding, the pressing action part of the adjusting member presses and drives the push member and / or the sliding member to slide along the track of the heart-shaped slide groove. When sliding, the push member and / or the sliding member rebounds and slides on the rebound bracket by pressing the elastic member, and when rebounding, acts and drives the movable slide rail to slide and open on the fixed slide rail, so as to realize the movable slide rail pressing and rebounding to automatically slide and open on the fixed slide rail.

[0014] The movable part is provided with a reset action part and an avoidance part; when the movable slide rail is closed to a certain position, the movable part acts on the lever assembly through the reset action part, and drives the pusher and / or the sliding part to reset and slide on the rebound bracket through the lever assembly, and is positioned to the terminal initial position; when the movable slide rail is opened to a certain position, the lever assembly acts on the avoidance part of the movable part, and drives the movable part to rotate or swing on the connecting part, and the movable part avoids and disengages from the lever assembly when rotating or swinging.

[0021] When the movable slide rail is closed to a certain position relative to the fixed slide rail, the movable member acts to drive the pressing rebound device to return to the terminal initial position.

[0022] Wherein, when the pressing rebound device is reset to the terminal initial position, a certain closing stroke is formed between the movable slide rail and the fixed slide rail.

[0023] When the movable slide rail is closed relative to the fixed slide rail and both are at a certain position of the closing stroke, the movable slide rail acts through the toggle part and drives the damping device to generate a damping force to achieve damping sliding closing between the movable slide rail and the fixed slide rail.

[0024] When the left and right movable slide rails are closed to a certain position by damping sliding, they are closed on the left and right fixed slide rails by synchronous sliding through the cooperation of the synchronous action part and the synchronous device.

[0025] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0026] 1. A synchronous action part and a movable part are arranged on the same connecting part of the left and right movable slide rails, and a synchronous device and a press-rebound device are arranged on the same assembly part of the left and right fixed slide rails, which effectively improves the connection compactness between the components and can also reduce the position of the synchronous action part, the movable part, the synchronous device and the press-rebound device occupied by the movable and fixed slide rails, making the volume of the entire furniture product smaller. At the same time, it simplifies the assembly process of the synchronous action part, the movable part, the synchronous device and the press-rebound device, avoiding the problem that the user needs to reserve an additional assembly position when assembling the above-mentioned components, or the assembly position is not enough to affect the interaction of the above-mentioned components, thereby further improving the use stability of the furniture product.

[0027] 2. When in use, the user drives the movable slide rail to slide through tools or manual action. When sliding, the left and right movable slide rails are synchronously slid and opened on the left and right fixed slide rails through the cooperation of the synchronous action part, the synchronization device, the pressing action component, and the pressing rebound device, thereby achieving automatic synchronous opening of the left and right movable slide rails, effectively avoiding the problem of installing handles on furniture products, resulting in increased production costs and affecting the appearance of furniture products; at the same time, the user only needs to press any position of the left and / or right movable slide rails to achieve automatic synchronous opening of the left and right movable slide rails, effectively improving the user experience; when closing, the left and right slide rail components can also be synchronously closed through the cooperation of the synchronous action part and the synchronization device, effectively avoiding the problem of inconsistent closure of the left and right slide rail components and affecting the stability of furniture products.

[0028] 3. The pressing action component is composed of a pressing bracket and an adjusting member, wherein the pressing bracket is made of a metal material and has left and right bending parts or positioning members for reinforcement, which effectively reduces the production cost. The setting of the left and right bending parts or positioning members can well withstand the force generated by the mutual pressing and rebounding action of the adjusting member and the pressing and rebounding device, thereby reducing the problem that the pressing bracket is easily bent and damaged due to the action force, thereby ensuring the structural strength of the pressing action component; the adjusting member can move forward and backward on the pressing bracket, and can realize the adjustment of the pressing and rebounding action position between the movable slide rail and the fixed slide rail when moving forward and backward, so that the user can adjust the pressing and rebounding action position between the movable slide rail and the fixed slide rail at any time according to actual use requirements, so as to ultimately avoid the problem that the two cannot press and rebound each other normally due to inconsistency in manufacturing specifications or inaccurate assembly positions, so that the two cannot automatically slide and open on the fixed slide rail due to the inconsistency in manufacturing specifications or inaccurate assembly positions, thereby simplifying the manufacturing process of the pressing and rebounding device and the pressing action part, and reducing the assembly accuracy between the pressing and rebounding device and the pressing action part.

[0029] 4. Due to the setting of the through hole, the adjusting member has enough front and rear positions to move when it is positioned and rotated in the through hole, thereby increasing the adjustment range of the adjusting member, making the adjustment distance of the pressing and rebounding position between the movable slide rail and the fixed slide rail larger, and better meeting the user's usage needs.

[0030] 5. The lever assembly of the press-rebound device will act when the movable slide rail is opened and drive the movable part to rotate or swing. The movable part will avoid and disengage from the press-rebound device when rotating or swinging. Therefore, the movable part will not affect the working state of the lever assembly and the press-rebound device when the movable slide rail slides open, so as to improve the use stability of the furniture product; the movable part acts when the movable slide rail is closed to a certain position and drives the lever assembly to reset and slide on the sliding part. When resetting and sliding, the lever assembly drives the push member and the sliding part to reset and slide, and is positioned on the heart-shaped slide groove, so as to realize the reset of the press-rebound device to the terminal initial position; because the lever assembly is transmission-connected to the sliding part, the force arm between the movable part and the first lever of the lever assembly is greater than The lever arm between the sliding part and the second lever of the lever assembly, therefore, under the mutual transmission of force and the change of the length of the lever arm, the force of the press-rebound device to reset will be smaller than the force to open it, so the connection between the lever assembly and the press-rebound device can effectively offset the opening elastic force of the press-elastic part acting on the push member, so that the user can use a closing force that is smaller than the opening pressing force to achieve the reset of the press-rebound device and the sliding closure of the movable slide rail, effectively avoiding the problem that the press-rebound device cannot automatically reset after work, and the user is easy to touch it after opening the movable slide rail, causing damage to the press-rebound device and affecting the appearance of the product, making it safer, more convenient, worry-free and labor-saving for users to use.

[0031] 6. A toggle part is provided on the movable slide rail, and a damping device is provided on the fixed slide rail. When the rebound device is pressed to reset to the terminal initial position, a certain closing stroke is formed between the movable slide rail and the fixed slide rail. When the movable slide rail continues to close, the movable slide rail acts through the toggle part and drives the damping device to generate a damping force. The movable slide rail will automatically slide and close on the fixed slide rail with a damping force, thereby further avoiding the collision between the movable slide rail and the fixed slide rail due to closing, resulting in a short product service life and affecting the furniture usage experience. At the same time, it can further reduce the closing force applied by the user on the movable slide rail.

[0032] In general, it has the characteristics of simple and reasonable structure, reliable performance, compact connection between components, long service life, low manufacturing cost, quick and convenient disassembly and assembly, high flexibility and wide range of use, and strong practicality.
