DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with embodiments.

[0024] See also Figure 1-6The utility model provides an anti-drop hook structure for a drawer slide and a drawer slide, comprising a main guide rail 1, a first auxiliary guide rail 2 and a second auxiliary guide rail 3. A first mounting hole 101 is provided on the back side of the main guide rail 1, a first guide block 102 is fixedly connected to the upper and lower surfaces of the main guide rail 1, a first guide groove 201 matching the first guide block 102 is provided on the upper and lower surfaces of the first auxiliary guide rail 2, a second guide block 202 is fixedly connected to the upper and lower surfaces of the first auxiliary guide rail 2, a positioning column 203 is fixedly connected to the front side of the first auxiliary guide rail 2 near the middle part, a second guide groove 302 matching the second guide block 202 is provided on the upper and lower surfaces of the second auxiliary guide rail 3, a second mounting hole 301 is opened on the front side of the second auxiliary guide rail 3, a stopper 303 is fixedly connected to the left end of the second auxiliary guide rail 3, an anti-drop mechanism 4 is fixedly installed in the main guide 1, and an anti-drop block 204 is provided on the left part of the back side of the first auxiliary guide rail 2.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the upper and lower surfaces of the anti-slip block 204 are provided with rubber strip blocks 2041 matching the anti-slip mechanism 4 , and the left side of the anti-slip block 204 is fixedly connected to the first secondary guide rail 2 with a stop block 2042 .

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the top surface of the rubber strip block 2041 is arranged in a wave shape and gradually increases from left to right.

[0027] Further as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that the anti-slip mechanism 4 includes a mounting plate 401, which is fixedly installed in the main guide rail 1 and arranged between the first guide blocks 102. A limited sliding groove 402 is provided on the mounting plate 401, and the limited sliding groove 402 is fixedly connected to a mounting frame 403 on the right side of the mounting plate 401. A movable block 404 slides up and down in the mounting frame 403, and a spring 405 is fixedly connected between the two movable blocks 404. The front side of the movable block 404 is rotatably connected to a limited wheel 406, and a rubber ring is sleeved on the limited wheel 406, and is arranged at an interval up and down through the movable block 404, and the upper and lower surfaces of the limited wheel 406 are at the same horizontal height as the upper and lower surfaces of the rubber strip block 2041;

[0028] The first sub-guide rail 2 slides in the main guide rail 1 through the first guide groove 201. During the continued operation, when the right end of the rubber strip block 2041 contacts the limiting wheel 406, the limiting wheel 406 rotates, and at the same time increases the friction between the two, which makes it difficult for the first sub-guide rail 2 to slide. As the rubber strip block 2041 gradually increases, it will squeeze the limiting wheel 406. The limiting wheel 406 slides on the movable block 404 in the mounting frame 403, so that the two limiting wheels 406 move relative to each other. When the two limiting wheels 406 move to contact each other, the limiting wheels 406 are difficult to rotate, thereby limiting the first sub-guide rail 2 to prevent the first sub-guide rail 2 from continuing to slide in the main guide 1, thereby realizing the anti-slip work of the first sub-guide rail 2.

[0029] According to the above working process, it can be known that: by cooperating with the anti-slipping mechanism 4 and the anti-slipping block 204 arranged on the first sub-guide rail 2, when the drawer is pulled out, the first sub-guide rail 2 slides in the main guide rail 1 driven by the second sub-guide rail 3, and when sliding to the longest distance, the anti-slipping block 204 limits the first sub-guide rail 2 in the anti-slipping mechanism 4, restricts its sliding, and thereby prevents it from detaching from the main guide rail 1.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the first sub-guide rail 2 slides on the first guide block 102 through the first guide groove 201 and maintains a sliding connection between the back side and the mounting plate 401, the second sub-guide rail 3 slides on the second guide block 202 through the second guide groove 302, and the main rail 1 and the first guide block 102, the first sub-guide rail 2 and the first guide groove 201, the second guide block 202 and the second sub-guide rail 3 and the second guide groove 302 can be obtained through integrated processing.

[0031] This scheme has the following working process: when this device is used, the main guide rail 1 is installed on the inner wall of the cabinet through the first mounting hole 101, and the second auxiliary guide rail 3 is installed on the side wall of the drawer through the second mounting hole 301. In the process of pulling the drawer, the second auxiliary guide rail 3 is first made to slide in the first auxiliary guide rail 2 through the second guide groove 302, so that the drawer runs a stroke. When the stopper 303 runs to contact the positioning column 203, the positioning column 203 is limited and pushed, so that the first auxiliary guide rail 2 slides in the main guide rail 1 through the first guide groove 201. In the process of continuing to run, when the right end of the rubber strip block 2041 contacts the limiting wheel 406, the limiting wheel 40 6 rotates, and at the same time increases the friction between the two, which makes it difficult for the first sub-guide rail 2 to slide, and because the rubber strip block 2041 gradually increases, it will squeeze the limiting wheel 406, and the limiting wheel 406 slides on the movable block 404 in the installation frame 403, so that the two limiting wheels 406 move relative to each other. When the two limiting wheels 406 move to contact each other, it is difficult for the limiting wheels 406 to rotate, and then the first sub-guide rail 2 is limited to prevent the first sub-guide rail 2 from continuing to slide in the main rail 1, thereby realizing the anti-falling work of the first sub-guide rail 2, and through the setting of the stop block 2042, the anti-falling property of the first sub-guide rail 2 is further improved, and the practicality of the device is improved.

[0032] In summary: by setting the anti-slip mechanism 4 in cooperation with the anti-slip block 204 set on the first sub-guide rail 2, when the drawer is pulled out, the first sub-guide rail 2 slides in the main rail 1 driven by the second sub-guide rail 3. When sliding to the longest distance, the anti-slip block 204 limits the first sub-guide rail 2 in the anti-slip mechanism 4 to restrict its sliding, thereby preventing it from detaching from the main rail 1. Through the coordinated sliding setting of the main rail 1, the first sub-guide rail 2 and the second sub-guide rail 3, they can remain stable during their mutual movements, thereby improving the stability of the drawer when sliding and avoiding jamming.
