Detailed Description

The technical solution of the present invention will be described in detail and fully with reference to the accompanying drawings and examples.

Examples

Referring to fig. 1 to 3, the cart for assisting the stopping of the tire of the vehicle provided by the present embodiment includes a rectangular frame 1, a hand pushing frame 2 is fixedly disposed on a rear beam 11 of the rectangular frame 1, fixing plates 3 are respectively and fixedly disposed on the outer sides of the front ends of a left beam 12 and a right beam 13 of the rectangular frame 1, a triangular stopping block 4 is fixedly connected to each side of the fixing plate 3, and a universal wheel 5 with a brake is disposed at the bottom of the rear beam 11 of the rectangular frame 1.

In this embodiment:

the rectangular frame 1 is formed by welding 4 steel pipes, so that the stability of the trolley can be improved, and the trolley is convenient to process and manufacture.

The hand push frame 2 is formed by vertically welding two vertical steel pipes 21 and a handrail handle 22, and the height of each vertical steel pipe 21 is 80-100 cm, so that a user does not need to bend down; the hand push frame 2 can be vertically welded on the rear beam 11 of the rectangular frame 1 through two vertical steel pipes 21 to be fixedly connected with the rectangular frame 1, so that the manufacturing and the stability of the trolley are improved.
