Quick device for manually dismounting and mounting tire and use method of quick device

Abstract

The invention relates to a tool for manually dismounting and mounting a tire in vehicle maintenance detection equipment, and particularly relates to a quick device for manually dismounting and mounting a tire and a use method of the quick device. The device mainly comprises an upright column, a supporting shaft and a three-jaw chuck; a tire pressing bar is arranged on the upright column, a tire pressing spade is arranged on the tire pressing bar, a cam is arranged on the upright column, and an extension spring is arranged between the upright column and one end of the cam; a clamping block is arranged on the upright column, one end of the clamping block is positioned on the protruded face of the cam, and the clamping head end of the clamping block is positioned at the inner side of the upright column on which a platform is arranged; and a cone pulley is arranged on the supporting shaft; a pedal is arranged on the upright column, and a rope is connected between the pedal and one end of the cam; and the connection between the upright column and the tire pressing bar, between the tire pressing bar and the tire pressing spade, between the upright column and the cam and between the upright column and the clamping block is achieved by movable shafts. The device can meet the requirements of tire dismounting, mounting and maintenance of various vehicles such as motorcycles, cars and electric vehicles, and the problems that the existing manual tire changers are troublesome in mounting and dismounting and time-wasting, the power source tire changers can not work without a power source, and the like are solved.

Description

Technical field [0001] The invention relates to a manual tire removal and installation tool for vehicle maintenance and testing equipment, in particular to a quick manual tire removal and installation device and a use method thereof. Background technique [0002] Traditional tire changers mainly use electricity, compressed air and hydraulic pressure as power sources. Although they reduce human physical labor, they are inseparable from power sources. Without power source equipment, they cannot work, and vehicle repair stations cannot provide customers. Tire repair service; in addition, the tire size range of existing equipment maintenance is narrow. To complete the disassembly and assembly of a variety of tires, the vehicle repair station needs to prepare at least two equipment, and the purchase, operation, and maintenance costs are high; third, this Equipment that requires power source drive cannot be carried with the vehicle and cannot be repaired on site. When the vehicle is dr...
