[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The utility model provides a technical solution: a drawer pushing mechanism for a drawer cabinet, comprising a cabinet body 1 and a self-locking mechanism 3, an inner drawer 2 is embedded in the cabinet body 1, a self-locking mechanism 3 is provided on one side of the surface of the cabinet body 1, and a shock absorbing mechanism 4 is provided at one end of the cabinet body 1;

[0025] The self-locking mechanism 3 includes a limiting groove 301, a first sliding groove 302, a first installation groove 303, a second installation groove 304, a first sliding rod 305, a first spring 306, a second sliding groove 307, a second spring 308, a fixing block 309, a first limiting block 310, a button 311, a slider 312, a second sliding rod 313, a third spring 314 and a clamping block 315. A limiting groove 301 is provided on one side of the surface of the cabinet 1, a first sliding groove 302 is provided on one side of the surface of the inner drawer 2, a first installation groove 303 is provided on one side of the limiting groove 301, a second installation groove 304 is provided on one end of the first sliding groove 302, a first sliding rod 305 is embedded in the interior of the first sliding groove 302, and a first spring 306 is installed on one side of the first installation groove 303. 6. A second sliding groove 307 is provided on one side of the first mounting groove 303, a second spring 308 is installed on one side of the surface of the second mounting groove 304, a fixed block 309 is fixedly connected to the surface of the first slide bar 305, one end of the first slide bar 305 is connected to the first limiting block 310, the other end of the first slide bar 305 is connected to the button 311, a slider 312 is embedded in the surface of the first slide bar 305, a second slide bar 313 is embedded in the interior of the second sliding groove 307, one side of the first limiting block 310 is fixedly connected to the third spring 314, and one side of the second slide bar 313 is connected to the clamping block 315. 06. The second slide groove 307, the second spring 308, the fixed block 309, the first limit block 310, the button 311, the slider 312, the second slide rod 313, the third spring 314 and the block 315 are arranged. When the inner drawer 2 needs to be pulled out from the cabinet body 1, the button 311 is pressed, the first slide rod 305 drives the fixed block 309 and the first limit block 310 to move, and the fixed block 309 drives the second spring 308 to stretch and deform, thereby causing the slider 312 to move toward the block 315. When the slider 312 and the block 315 are in contact with each other, the slider 312 presses the block 315, so that the block 315 drives the second slide rod 313 to move. At the same time, the movement of the second slide rod 313 causes the first spring 306 to compress and deform, and finally drives the block 315 When the first locking block 310 is in the unlocking state, the locking block 315 is released, and the locking block 315 is pushed into the unlocking state, so that the locking block 310 and the second locking block 315 can be unlocked.

[0026] Furthermore, the position of the limit groove 301 is relatively aligned with the second installation groove 304, and there are two groups of limit grooves 301. Through the setting of the limit grooves 301, the limit grooves 301 are set on the cabinet body 1, and are usually set in multiple groups. Such a design enables the inner drawer 2 to be firmly fixed on the cabinet body 1 to achieve stable positioning. At the same time, when the inner drawer 2 reaches the specified position, the cooperation between the limit groove 301 and the block 315 can effectively prevent the inner drawer 2 from accidentally rotating or loosening due to external force, ensuring that the precise position after installation is not easily changed.

[0027] Furthermore, the first limit block 310 is embedded in the inside of the limit groove 301, and the first limit block 310 is in contact with one side of the blocking block 315. Through the setting of the first limit block 310, the first limit block 310 is used in conjunction with the limit groove 301. When the inner drawer 2 is in place, the first limit block 310 enters the limit groove 301 under the drive of the first slide rod 305, and locks the inner drawer 2 in a predetermined position. This design can effectively prevent the inner drawer 2 from loosening under force or vibration, realize the fixing function, and ensure the stability of the connection.

[0028] Furthermore, the other sides of the first spring 306 and the second spring 308 are connected to the card block 315 and the fixed block 309 respectively. The first slide bar 305 forms a mutual sliding structure with the first slide groove 302 through the second spring 308, and the second slide bar 313 forms a mutual sliding structure with the second slide groove 307 through the first spring 306. Through the arrangement of the first slide bar 305 and the second slide bar 313, when the inner drawer 2 is in place, the first slide bar 305 pushes the first limit block 310 into the limit groove 301, realizing the inner drawer 2 The first limit block 310 cooperates with the limit groove 301 under the push of the first slide bar 305 to prevent the inner drawer 2 from loosening due to vibration or external force, which enables the first slide bar 305 to play a control and locking role in the entire self-locking process. The second slide bar 313 cooperates with the second slide groove 307 to ensure that the sliding component in the self-locking mechanism 3 moves on a specific track, playing a role of precise guidance and auxiliary positioning, which makes the entire self-locking and unlocking process smoother and effectively avoids the sliding component from deflecting or getting stuck.

[0029] Furthermore, the slider 312 is located between the fixed block 309 and the first limit block 310, and the other side of the third spring 314 is connected to the slider 312. Through the setting of the fixed block 309, the fixed block 309 maintains the pressure of the second spring 308 through its position. During the process of fixing or unlocking the inner drawer 2, the second spring 308 applies a reaction force to the first slide rod 305 through the fixed block 309, ensuring that the slide rod can be smoothly reset after being unlocked.

[0030] Furthermore, there are four groups of first mounting grooves 303 and second slide grooves 307, and they are distributed at equal angles on the limiting groove 301. Through the setting of the first mounting grooves 303, the four groups of first mounting grooves 303 distributed at equal angles are embedded with clamping blocks 315, so that the first limiting blocks 310 can be clamped inside the limiting groove 301 in all directions, thereby increasing the stability of the mechanism when locked. At the same time, the setting of multiple groups of first mounting grooves 303 increases the seismic resistance of the equipment and extends the service life of the equipment.

[0031] Furthermore, the shock absorbing mechanism 4 includes a third slide groove 401, a groove 402, a pulley 403, a fourth spring 404 and a second limit block 405. The third slide groove 401 is provided on both sides of the cabinet 1, and a groove 402 is provided on one side of the third slide groove 401. The pulley 403 is embedded in the interior of the third slide groove 401, and one end of the groove 402 is connected to the fourth spring 404. The other side of the fourth spring 404 is connected to the second limit block 405. Through the arrangement of the third slide groove 401, the groove 402, the pulley 403, the fourth spring 404 and the second limit block 405, When the inner drawer 2 is pushed into the cabinet body 1, the pulley 403 on the surface of the inner drawer 2 slides into the third slide groove 401 of the cabinet body 1. The friction between the pulley 403 and the slide groove and the fourth spring 404 in the groove 402 generate resistance to the pulley 403. At the same time, the fourth spring 404 is connected to the second limit block 405. The second limit block 405 can compress the spring as the inner drawer 2 is pushed in, thereby increasing the damping effect and making the inner drawer 2 have a smooth buffering force when closing. By distributing multiple groups of grooves 402 and springs at equal intervals, the shock absorption effect can be further enhanced and the service life of the device can be extended.

[0032] Furthermore, eight groups of grooves 402 are provided on the third slide groove 401 and are distributed at equal intervals. The other side of the pulley 403 is embedded in the interior of the inner drawer 2. Through the setting of the groove 402, the groove 402 cooperates with the fourth spring 404 to provide resistance by compressing the spring, so that the inner drawer 2 is effectively buffered when closing. When the inner drawer 2 is pushed into the cabinet body 1, the pulley 403 enters the groove 402, pushes and compresses the fourth spring 404, thereby generating a rebound force, so that the movement of the inner drawer 2 gradually slows down, achieving the effect of buffering and shock absorption.

[0033] Working principle: When the inner drawer 2 needs to be pulled out from the cabinet 1, the button 311 is pressed, the first slide bar 305 drives the fixed block 309 and the first limit block 310 to move, the fixed block 309 drives the second spring 308 to stretch and deform, and then the slide bar 312 moves toward the block 315. When the slide bar 312 and the block 315 fit together, the slide bar 312 presses the block 315, so that the block 315 drives the second slide bar 313 to move, and at the same time the second slide bar 31 3 makes the first spring 306 compress and deform, and finally drives the block 315 to move into the first mounting groove 303. When the other end of the block 315 completely passes the slider 312, the button 311 is released, and the second spring 308 rebounds and deforms, driving the first slide bar 305 to move. The first slide bar 305 drives the first limit block 310 and the block 315 to move. At the same time, the movement of the block 315 makes the third spring 314 compress and deform. When one side of the block 315 When the first limit block 310 is in contact with the first limit block 310, the first limit block 310 will be disengaged from the restriction of the card block 315 through the slider 312, thereby causing the first limit block 310 and the slider 312 to move from one side of the limit groove 301 to the second installation groove 304. When one side of the first limit block 310 is completely out of the limit groove 301, it can be pulled out. When the inner drawer 2 is pushed into the cabinet body 1, the pulley 403 on the surface of the inner drawer 2 slides into the third slide groove 401 of the cabinet body 1. The friction between the pulley 403 and the slide groove and the fourth spring 404 in the groove 402 generate resistance to the pulley 403. At the same time, the fourth spring 404 is connected to the second limit block 405. The second limit block 405 can compress the spring as the inner drawer 2 is pushed in, thereby increasing the damping effect, so that the inner drawer 2 has a smooth buffering force when closing. By evenly distributing multiple groups of grooves 402 and springs, the shock absorption effect can be further enhanced and the service life of the device can be extended.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
