As shown in fig. 4, the latch assembly 400 includes a retraction limiter 410 and a latch switch provided on the drawer body 200. As shown in fig. 5, the retraction limiter 410 is provided with a retraction limiter fixing hole 411, and the retraction limiter 410 is inserted into the retraction limiter fixing hole 411 through a connecting piece such as a screw, so as to fix the retraction limiter 410 on the drawer body 200, so that the retraction limiter 410 extends out of the side wall 230 of the drawer body. As shown in fig. 6 to 9, the latch switch includes a retractable latch slider 422, which can abut against the retraction limiter 410 to limit the retraction of the drawer body 200 when the latch slider 422 is extended. In this embodiment, the retraction limiter 410 is disposed outside the side wall 230 of the drawer body, and accordingly, the latch switch and the retraction limiter 410 are disposed outside the drawer body 200, and the latch slider 422 in the latch switch can contact the retraction limiter 410 when extending.

As an alternative embodiment, the retraction assembly 300 is disposed outside the bottom 220 or outside the side wall of the drawer body and the slide rail assembly 100 is disposed outside the bottom 220 or outside the side wall of the drawer body.

In the present embodiment, as shown in fig. 3 and 5, the retraction assembly 300 is disposed outside the bottom 220 of the drawer body, and in order to avoid interference of the retraction assembly 300 with the slide rail assembly 100, the slide rail assembly 100 is disposed outside the side wall 230 of the drawer body. Wherein, the retraction elastic members 310 of the retraction assembly 300 are two, and the bottom outer sides of the drawers are disposed relatively parallel along the drawing direction of the drawers. The two sets of sliding rail assemblies 100 are respectively arranged outside the side walls of the drawer relatively in parallel along the drawing direction of the drawer.

In other embodiments, the retraction assembly 300 may be disposed outside of the side wall 230 of the drawer body and the slide rail assembly 100 may be disposed outside of the bottom 220 of the drawer body. In addition, the retraction assembly 300 and the slide rail assembly 100 may also be disposed outside the bottom 220 of the drawer body or outside the side wall 230 of the drawer body at the same time. The particular retraction assembly 300 placement and the slide rail assembly 100 placement can be adapted by those skilled in the art according to particular needs.

As an alternative embodiment, as shown in fig. 3 to 5, the retraction assembly 300 further includes a buffering device 320, the buffering device 320 is provided on the drawer body 200 and/or the drawer slot 21, the force of the buffering device 320 is opposite to the force of the retraction elastic member 310, and the force of the buffering device 320 is smaller than the force of the retraction elastic member 310. The damper 320 may be a liquid damper, a gas damper, or an electromagnetic damper. Optionally, the buffer device 320 includes a gas spring rod 321, the gas spring rod 321 is disposed on the outer side of the bottom of the drawer body 200, and a gas spring rod stop 322 is disposed in the drawer slot 21 corresponding to the gas spring rod 321.

the lock catch slide block 422 and the slide block 4221 limiting parts are respectively fixed on the shell 421 and are respectively guided and fixed through the lock catch slide block fixing guide hole 4211 and the slide block limiting rod fixing guide hole 4212, the tail ends of the lock catch slide block 422 and the slide block limiting rod fixing guide hole 4212 are sleeved with a reset spring, the reset spring is compressed to enable the lock catch slide block 4221 to keep an outwards ejected pre-tightening state, and the reset spring is compressed to enable the slide block limiting part 423 to keep an outwards ejected pre-tightening state; when the button 4231 is pressed, the whole slider limiting member 423 moves upward in fig. 8, the slider limiting inclined surface 4234 pushes the slider guiding inclined surface 4224 to move rightward in fig. 8, both return springs are in a compressed state, when the button 4231 is released, the return force of the return springs pushes the lock catch slider 422 open to the left in fig. 8, the return force of the return springs pushes the button 4231 back to the original position, and the left-right movement of the lock catch slider 4221 is realized by pressing the button 4231, so that the retraction limiting member 410 can be blocked or released.

The working principle of the automatic retraction drawer 10 of the present application is as follows:

when the drawer handle is pulled by hand to pull the drawer body 200 outwards, the drawer body 200 moves outwards, the retraction elastic member 310 is in a stretched state, and when the retraction limiting member 410 arranged on the drawer body 200 is not contacted with the locking slider 4221 of the locking switch, the drawer handle is released, the drawer body 200 can be automatically retracted under the rebound pulling force of the retraction elastic member 310, and the drawer closing state is restored.

When the retraction limiter 410 on the drawer body 200 moves to touch the contact slope 4225 of the latch slider 4221, the inclined end of the retraction limiter 410 applies a force to the latch slider 422, so that the latch slider 422 retracts, at this time, the return spring on the latch slider 422 is in a compressed state, the latch slider 422 cannot block the retraction limiter 410 to continue to move outwards, when the end of the retraction limiter 410 completely passes through the slider 4221, the slider 4221 pushes the slider 4221 to the left outermost side under the resilience force of the return spring, when the hand stops pulling the drawer handle to draw outwards, the drawer body 200 is retracted under the pulling force of the retraction assembly 300, and when the retraction limiter 410 on the drawer retracts to the end of the slider 4221 and is blocked by the end of the slider 4221, the retraction cannot be continued, at this time, the drawer body 200 is limited and fixed, and things in the drawer can be conveniently taken out. When the drawer is to be pushed back, the button 4231 is pressed again, the tail end of the sliding block 4221 is retracted, the retraction limiting part 410 is limited again, the drawer body 200 is retracted by the resilience force of the retraction assembly 300, the drawer is slowly reset, when the air spring rod 321 on the drawer body 200 is propped against the air spring rod 321 stop on the table, the air spring rod 321 is subjected to the thrust of the reaction, and because the elasticity of the selected air spring rod 321 is smaller than the tension of the retraction elastic part 310, the drawer body 200 is always in the retraction direction due to the retraction force, but is buffered by the air spring rod 321, the drawer is slowly retracted, and cannot be quickly retracted, so that the drawer is prevented from being clamped by hands carelessly. As the drawer body 200 continues to be retracted, until the drawer stop is pushed, the drawer stops the pull-out motion,

based on the same inventive concept, the embodiment of the present application also provides a furniture 20 with an automatically retracting drawer, as shown in fig. 1 to 3, the furniture 20 with an automatically retracting drawer is provided with a drawer slot 21, and the drawer slot 21 is provided with the automatically retracting drawer 10.
