Hoisting device for spare tire of truck

Abstract

The invention discloses a hoisting device for a spare tire of a truck. The hoisting device for the spare tire of the truck comprises a device main body, a hoisting device body, a frame bottom plate and a hoisting device, wherein a second connecting seat is arranged on the right side of the bottom end of the hoisting device and is fixedly connected with the frame bottom plate; a rotating shaft is arranged in the middles of the first connecting seat and the second connecting seat, and is movably connected with the first connecting seat and the second connecting seat; a lifting iron chain is arranged under the rotating shaft and is movably connected with the rotating shaft; a tray is arranged at the bottom end of the lifting iron chain, and is movably connected with the lifting iron chain; the arranged tray is cross-shaped; four protruded portions are separately connected with second connecting rods separately; when the spare tire is hoisted on the frame bottom plate, the tray, and the four first connecting rods in the vertical direction jointly form a rectangular net bag; the ability of fixing the spare tire of the device main body is improved; and meanwhile, when an automobile runson a bumpy road surface, the circumstance that the spare tire shakes along with the truck, and impacts a truck body to make noises can be avoided.

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...
