Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 , the utility model provides a technical solution: a forklift anti-dumping device, comprising a forklift 1, support mechanisms 2 are arranged at both ends of the forklift 1, and an adjustment mechanism 3 is arranged at one end of the forklift 1;

[0022] The supporting mechanism 2 includes a connecting shell 201, a first bearing 202, a rotating rod 203, a rotating plate 204, a first spring 205, a moving plate 206, a connecting rod 207, a second bearing 208, a supporting block 209, a clamping slot 210, a receiving slot 211, a second spring 212, a clamping block 213 and a pull rod 214. The connecting shell 201 is fixedly connected to the two side surfaces of the forklift 1. The first bearing 202 is arranged inside the connecting shell 201. One end of the first bearing 202 is connected to the rotating rod 203, one end of the rotating rod 203 is connected to the rotating plate 204, the interior of the rotating plate 204 is fixedly installed with a first spring 205, one end of the first spring 205 is fixedly connected to the moving plate 206, one end of the moving plate 206 is provided with a connecting rod 207, both ends of the connecting rod 207 are provided with a second bearing 208, the outer wall of the second bearing 208 is connected to a support block 209, and the connecting shell 201, the first bearing 202, the rotating rod 203, the rotating plate 204, the first spring 205, the moving plate 206, the connecting rod 207, the second bearing 208, the outer wall of the second bearing 208, the connecting shell 201, the first bearing 202, the rotating rod 203, the rotating plate 204, the first spring 205, the moving plate 206, the connecting rod 207, the second bearing 208 ... 5. The arrangement of the movable plate 206, the connecting rod 207, the second bearing 208 and the supporting block 209. When transporting goods, the pull rod 214 is pulled, and the pull rod 214 drives the block 213 to enter the receiving groove 211. At this time, the block 213 leaves the groove 210, and the rotating plate 204 can rotate. One end of the rotating plate 204 leaves the connecting shell 201, and the first spring 205 drives the movable plate 206 to move outward, and the movable plate 206 drives the supporting block 209 to leave the rotating plate 204. Then, the support block 209 is rotated to a position horizontal to the ground, so that the support block 209 can support the forklift 1, so that the forklift 1 will not tip over during the transportation of goods. When the forklift 1 is not in use, the support block 209 and the movable plate 206 are pushed into the rotating plate 204, and then the rotating plate 204 is moved into the connecting shell 201. At this time, the clamping block 213 is clamped into the clamping slot 210, so that the rotating plate 204 is fixed in the connecting shell 201, so that the occupied area can be reduced when the forklift 1 is not in use.

[0023] Furthermore, a slot 210 is provided on one side surface of the rotating plate 204, and a receiving slot 211 is provided on one side of the inner wall of the connecting shell 201. A second spring 212 is fixedly installed inside the receiving slot 211, and a block 213 is fixedly connected to one end of the second spring 212. A pull rod 214 is fixedly connected to one side surface of the block 213. By setting the pull rod 214, the pull rod 214 is pulled, and the pull rod 214 drives the block 213 to leave the slot 210, so that one end of the rotating plate 204 can rotate.

[0024] Furthermore, the rotating rod 203 forms a rotating structure with the connecting shell 201 through the first bearing 202, and the movable plate 206 forms a telescopic structure with the rotating plate 204 through the first spring 205. Through the setting of the first spring 205, when one end of the rotating plate 204 leaves the connecting shell 201, the first spring 205 will drive the movable plate 206 to move outward.

[0025] Furthermore, the support block 209 forms a rotating structure with the connecting rod 207 through the second bearing 208 . By setting the support block 209 , the support block 209 can be rotated to an angle horizontal to the ground to support the forklift 1 .

[0026] Furthermore, the block 213 forms a locking structure with the rotating plate 204 through the slot 210, and the block 213 forms a telescopic structure with the connecting shell 201 through the second spring 212. Through the arrangement of the second spring 212 and the block 213, when the block 213 is not squeezed, the second spring 212 will drive the block 213 to return to its position, so that the block 213 is stuck in the slot 210.

[0027] Further, the adjustment mechanism 3 includes a first drag rod 301, a slide groove 302, a slider 303, a connecting groove 304, a screw 305, a nut 306 and a second drag rod 307. The first drag rod 301 is provided at one end of the forklift 1, the slide groove 302 is provided inside the first drag rod 301, the slider 303 is provided inside the slide groove 302, a connecting groove 304 is provided on one side surface of the first drag rod 301, a screw 305 is welded on one side surface of the slider 303, a nut 306 is provided at one end of the screw 305, and a second drag rod 307 is fixedly connected to one side surface of the slider 303. Through the arrangement of the first drag rod 301, the slide groove 302, the slider 303, the connecting groove 304, the screw rod 305, the nut 306 and the second drag rod 307, before using the forklift 1, the nut 306 is loosened and the second drag rod 307 is pulled, at which time the slider 303 moves in the slide groove 302, and the screw rod 305 moves in the connecting groove 304, so that the second drag rod 307 moves at one end of the first drag rod 301, and after adjusting to a suitable position, the nut 306 is screwed on to complete the fixation, so that the position of the second drag rod 307 in the first drag rod 301 can be quickly adjusted as needed.

[0028] Furthermore, the slider 303 forms a sliding structure with the first drag rod 301 through the slide groove 302, and one end of the screw rod 305 passes through the connecting groove 304 and is threadedly connected with a nut 306. Through the setting of the slide groove 302 and the slider 303, when the slider 303 slides in the slide groove 302, it can drive the second drag rod 307 to move at one end of the first drag rod 301.

[0029] Working principle: before using the forklift 1, loosen the nut 306 and pull the second drag rod 307, at this time the slider 303 moves in the slide slot 302, and the screw 305 moves in the connecting slot 304, so that the second drag rod 307 moves at one end of the first drag rod 301, and after adjusting to a suitable position, screw on the nut 306 to complete the fixation, so that the position of the second drag rod 307 in the first drag rod 301 can be quickly adjusted as needed. When transporting goods, pull the pull rod 214, and the pull rod 214 drives the block 213 to enter the storage slot 211. At this time, the block 213 leaves the slot 210, and the rotating plate 204 can rotate. One end leaves the connecting shell 201, and the first spring 205 drives the moving plate 206 to move outward, and the moving plate 206 drives the supporting block 209 to leave the rotating plate 204, and then the supporting block 209 is rotated to a position horizontal to the ground, so that the supporting block 209 can support the forklift 1, so that the forklift 1 will not tip over during the transportation of goods. When the forklift 1 is not in use, the supporting block 209 and the moving plate 206 are pushed into the rotating plate 204, and then the rotating plate 204 is moved into the connecting shell 201. At this time, the card block 213 is carded into the card slot 210, so that the rotating plate 204 is fixed in the connecting shell 201, so that the occupied area can be reduced when the forklift 1 is not in use.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
