Spare tire hoisting device for truck

Abstract

The invention discloses a hoisting device for a spare tire of a truck, which comprises a device main body, a frame bottom plate and a hoisting device. A second connecting seat is arranged on the right side of the bottom end of the hoisting device, and the second connecting seat is fixedly connected with the frame bottom plate. A rotating shaft is arranged in the middle of the first connecting seat and the second connecting seat, and the rotating shaft is movably connected with the first connecting seat and the second connecting seat. A lifting iron chain is arranged under the rotating shaft, and the lifting iron chain is movably connected with the rotating shaft. The bottom of the lifting iron chain There is a tray at the end, and the tray is movably connected with the lifting chain. The shape of the tray is cross-shaped, and the four protruding parts are respectively connected with a second connecting rod. When the spare tire is hoisted on the bottom plate of the frame, the tray and The four first connecting rods in the vertical direction jointly form a rectangular net bag, which improves the ability of the main body of the device to fix the spare tire, and at the same time prevents the spare tire from shaking with the car and hitting the vehicle body to generate noise when the car is driving on a bumpy road.

Description

technical field [0001] The invention belongs to the technical field of trucks, in particular, the invention relates to a hoisting device for a spare tire of a truck. Background technique [0002] The hoisting device is a device used to fix the spare tire. During the driving of the car, once a wheel blows out or something goes wrong, the spare tire can be replaced conveniently and in time, so that the car will not break down halfway. [0003] The current spare tires of trucks are hoisted at the lower end of the vehicle frame by binding them with iron chains. During installation, people forcefully rotate the rotating shaft with ratchets, wind up the iron chains, lift them to the fastening position at the lower end of the vehicle frame, and then lock them through the connecting plate. However, the spare tire hoisted at the lower end of the truck shakes a lot when the car is running. With the bumping of the car, it produces a lot of noise, and the iron chain is easy to slip down...
