Portable tire disassembly device

Abstract

The invention relates to the technical field of motor vehicle maintenance, and in particular to a portable tire disassembly device. The portable tire disassembly device comprises a cylinder body and an oil cylinder. A tension spring, an ejector rod and a limiting sleeve are arranged in the cylinder body, and a claw body is movably connected to the left side of the cylinder body. The cylinder bodyis fixedly connected with the oil cylinder. A quick coupling is arranged on the connecting position. A slotted screw is arranged at the bottom of the quick coupling. A steel ball is arranged below theslotted screw, and the steel ball is located at an inclined oil way opening in the cylinder body. A tension rod is arranged in the oil cylinder, a connecting head is arranged on the right side of thetension rod, and a fixed handle is arranged on the connecting head. A damping screw is arranged on an oil inlet and outlet passage in the oil cylinder. The portable tire disassembly device has the characteristics of simple structure, convenient carrying and safe use and is especially suitable for the disassembly of large and medium-sized engineering vehicle tires, the operation is simple, and thedisassembly efficiency is high.

Description

technical field [0001] The invention relates to the technical field of motor vehicle maintenance, in particular to a portable tire removal device. Background technique [0002] In recent years, with the continuous popularization of automobiles in the domestic market, the automobile service industry has also continued to expand. As an important branch of the automobile service industry, automobile maintenance has also been developing continuously. Tire dismantling is the most common in car maintenance. The tire dismantling of small cars often uses proprietary equipment to separate the bead and steel ring, but the proprietary equipment is large in size, fixed in position, and expensive. The tires of large and medium-sized engineering vehicles are large in diameter and heavy in weight. When they need to be disassembled, due to the lack of special equipment, it is often necessary to use tools such as buckets, crowbars, hammers, etc., and adopt the original method of multi-person...

Patent No. "201621141894.7" introduces a tire remover, which is equipped with a claw body, claw feet, and feet, and is driven by an oil cylinder to separate the bead from the steel ring. The structure is simple and easy to carry, but the tire remover with this structure In the process of releasing the oil return, there is a great potential safety hazard, that is, the three parts of the bottom foot, the claw foot and the claw body return to their positions at the same time, which will cause the entire tire to bounce up because the steel ring is not firmly grasped, which is very easy to hurt. The operator, the internal structure design is unreasonable
