Description

Tire dismouting device

Technical Field

The utility model belongs to the technical field of dismouting device, concretely relates to tire dismouting device.

Background

When a tire of an electric vehicle or a motorcycle is repaired or replaced, it is often necessary to detach the tire and then mount the tire on a hub. Although power tools are often used when performing maintenance. However, only the process of changing the tire is to manually disassemble the tire by using two large screwdrivers or two tire prying rods. Need slowly sled the tire edge when the dismouting for tire edge and wheel hub separation or chucking are consuming time hard, still are easy to the wheel rim crushing, and the child lip is sled mashed, still easily sled the inner tube when having the inner tube mashed, and the workman also easily injures hand when carrying out the dismouting.

The wheel rim is slightly crushed, which affects the beauty of customers and causes the tire to be deflated. And the tire lip is damaged by prying, so that the risk of tire burst is left after air leakage if the tire lip is damaged by prying, and the tire is scrapped on the spot if the tire lip is damaged. For a vehicle with an inner tube, if the inner tube is broken by prizing, the inner tube needs to be replaced again, so that the time is delayed, and the economic loss is caused. The existing tire removing machine has the defects of complex structure, higher price, influence of electric power conditions on installation and complex operation, and does not support the disassembly and the assembly of the tires of motorcycles and electric vehicles.
