A tire removal device for a bicycle tire comprises a base, a sleeve, a wheel pressing device, a deflation mechanism, a sliding plate, a tire spoon, a shaft, a locking mechanism and a tire removal mechanism. When the bicycle tire needs to be removed, a middle shaft of a wheel set is inserted into the sleeve and the upper end of the middle shaft is pressed by the wheel pressing device to ensure thefirmness of the wheel set when the bicycle tire is removed; the air in an inner tube is discharged through the deflation mechanism; then the lower end of the tire spoon is brought into contact with the bicycle tire; the tire spoon is turned and the lower end of the tire spoon presses the bicycle tire down to deform one end of the bicycle tire; the tire spoon continues to be turned and slides alonga long hole through a pin during rotation; the lower end of the tire spoon is rotated into the bicycle tire to lift up one end of the bicycle tire so as to detach the bicycle tire from a rim; the tire removal mechanism is inserted into the bicycle tire at the position that the bicycle tire is lifted up; and then the tire removal mechanism rotates a circle to completely lift up one side end of thebicycle tire from the rim. The tire removal device for the bicycle tire improves the efficiency of tire removal, and improves the safety during tire removal since sharp tools are not needed for the entire operation.
Description
technical field [0001] The present invention relates to the field of bicycle maintenance tools, in particular to a bicycle tire removal device. Background technique [0002] As we all know, the main means of transportation for primary and middle school students to go to school is the bicycle. The tire structure of the bicycle is composed of a wheel set, an inner tube and an outer tire installed on the wheel set to wrap the inner tube inside it. Therefore, it is different from the tubeless tire structure of a car. When the bicycle tire has a puncture, it is necessary to utilize the tire prying tool to remove the outer tire from the wheel set before the punctured inner tube can be taken out and repaired. When prying tires, stick tools such as screwdrivers are generally used to pry tires, which is not only inefficient, but also easily causes human injury and affects the efficiency of tire repair. Contents of the invention [0003] In order to overcome the deficiencies of the...
