[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] A non-slip drawer comprises a drawer body 1 and a guide rail 2. The inner end side wall of the drawer body 1 placed on the guide rail 2 is symmetrically and elastically connected with a card block 3. The guide rail 2 is symmetrically provided with strip holes 201 adapted to the card block 3. The card block 3 is elastically connected to the drawer body 1. A traction mechanism 4 is fixedly installed between the card blocks 3. The traction mechanism 4 comprises two traction ropes 401 that pass through the drawer body 1 and are placed on the panel side. One end of the traction rope 401 is fixed to the card block 3.

[0034] Reference Figure 1-Figure 9 When the drawer body 1 is pulled, the card block 3 slides and adjusts in the strip hole 201 of the guide rail 2. With the cooperation of the card block 3 and the guide rail 2, the drawer body 1 can be prevented from falling off the guide rail 2 due to excessive force. When the drawer body 1 needs to be removed from the guide rail 2, the two traction ropes 401 are pulled to make the card block 3 shrink into the drawer body 1 and disengage from the strip hole 201. At this time, the drawer body 1 can be quickly removed from the guide rail 2.

[0035] The drawer body 1 is symmetrically provided with an installation opening 101 adapted to the card block 3. The card block 3 can be received in the installation opening 101. A plurality of springs 302 are fixed in the card block 3 and the installation opening 101. The traction mechanism 4 also includes a redirecting column 402 fixed in the installation opening 101. The traction rope 401 passes around the redirecting column 402 to form an L shape.

[0036] Reference Figure 6-Figure 9 The traction rope 401 passes through the rope threading hole 102 opened on the drawer body 1 and bypasses the redirection column 402, so that one end of the traction rope 401 is parallel to the sliding direction of the block 3, so that when the traction rope 401 is pulled, the block 3 slides smoothly, and the block 3 compresses the spring 302. After the traction rope 401 is released, the spring 302 rebounds elastically, so that the block 3 can be quickly reset.

[0037] The clamping block 3 symmetrically fixes the limiting block 301 , and the mounting opening 101 is symmetrically provided with limiting grooves 1011 adapted to the limiting block 301 .

[0038] Reference Figure 8 and Fig. 9 The outer end of the limiting groove 1011 is a closed structure, so as to ensure the sliding of the card block 3 through the cooperation between the limiting block 301 and the limiting groove 1011, and prevent the card block 3 from being separated from the installation opening 101.

[0039] A pull rod 403 is fixed to one end of the two traction ropes 401 away from the clamping block 3 .

[0040] Reference Figure 3 The pull rod 403 is used to pull the two traction ropes 401 synchronously, and finally the two clamping blocks 3 are synchronously retracted into the installation opening 101.

[0041] A plurality of locking screws 4031 which are threadedly connected to the panel side of the drawer body 1 are installed on the pull rod 403 .

[0042] Reference Figure 3 and Figure 6 The locking screw 4031 is passed through the pull rod 403 , and when the pull rod 403 is not in use, the locking screw 4031 is threadedly connected to the threaded hole 103 provided on the drawer body 1 to avoid misoperation of the pull rod 403 .

[0043] The redirection column 402 is provided with a rotatable sleeve 4021 .

[0044] Reference Figure 8 and Fig. 9 By rotating the sleeve 4021 sleeved on the redirection column 402, the wear of the traction rope 401 and the redirection column 402 can be reduced, and the service life of the traction rope 401 can be increased.

[0045] Working principle: when the pull rod 403 and the drawer body 1 are fixed by the locking screw 4031, the spring 302 rebounds elastically and makes the card block 3 protrude from the drawer body 1, and the card block 3 slides in the strip hole 201 to be stuck on the guide rail 2 through the card block 3 to prevent the drawer body 1 from being pulled out with excessive force; when the drawer body 1 needs to be removed from the guide rail 2, the locking screw 4031 is loosened to disengage it from the threaded hole 103, and then the pull rod 403 is pulled outward, and the traction rope 401 is pulled to drive the card block 3 to shrink toward the inside of the installation port 101, and at the same time the spring 302 is compressed, and the card block 3 is completely received in the installation port 101, and then the drawer body 1 can be removed from the guide rail 2. After it is installed again, the pull rod 403 is released, and the spring 302 rebounds elastically so that the card block 3 is stuck in the strip hole 201.
