Automobile tire dismantling device

Abstract

The invention discloses an automobile tire dismantling device which comprises a base, a telescopic device, a major axis, a disk external circle, spokes, a telescopic link, a rotary spanner, a hexagonal axis, a hexagonal tank and a disk inner circle, wherein the central location of the base is connected with one end of the telescopic device; the other end of the telescopic device is connected with the major axis, and the telescopic device is perpendicular to the major axis; the other end of the major axis is connected with the disk inner circle by the same center of circle; the spokes are arranged between the disk inner circle and disk outer circle, and expand divergently along the radial direction of the disk inner circle at equal angle intervals; one end of each spoke is connected with the disk inner circle, and the other end is connected with the disk outer circle; and one side of the disk inner circle adjacent to the major axis is coaxially provided with a circular hole into which the major axis can be matched and inserted. The automobile tire dismantling device is simple in structure; and by adding the disk and base units and adopting the lever principle, the automobile tire dismantling device is convenient and labor-saving for operation in the automobile tire mounting and dismantling process, thereby achieving the effect of stable mounting and dismantling.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to an assembly and disassembly tool for automobile tires. Background technique [0002] With the development of the world economy, the penetration rate of automobiles is getting higher and higher, and automobiles are developing in the direction of humanization. Car tires are an essential part of a car, and it is a normal accident if a tire leaks or blows out during driving. To replace a tire, tools such as a tire bolt removal tool and a jack are required. Thus, at present, vehicles are equipped with a tire bolt dismounting tool in the on-board tool. The current tire bolt dismounting tool is a rod-shaped tool with a sleeve, the front part is a sleeve, and the back is a booster rod. All in one design. Because the locking torque of the tire bolts is relatively large, and the length of the booster rod is fixed, it is not a big problem for adult males to disasse...

AI Technical Summary

Problems solved by technology

Because the locking torque of the tire bolts is relatively large, and the length of the booster rod is fixed, it is not a big problem for adult men to disassemble and install tires, but most women have difficulty dismounting and installing tire bolts. If the bolts are not tightened to the specified torque , the increased risk factor of driving
