Embodiment Construction
[0033] Attached below figure 1 to attach Figure 7 The present invention will be further described.
[0034] as attached figure 1 As shown, a bicycle tire removal device includes: a base 1, a column I2 is vertically arranged on one side, and a horizontal strut 3 is arranged horizontally on the top of the column I2; a sleeve 4 is vertically installed on the base 1 , its inner hole matches the outer diameter of the central shaft 9 of the wheel set 8, and the turntable I 5 is installed in the inner hole through the rotation of the bearing I 6; the pressing wheel device is installed on the cross strut 3, when the wheel set 8 After the lower end of the central shaft 9 is inserted into the sleeve 4, the pressing wheel device is pressed on the upper end of the central shaft 9; the deflation mechanism is arranged on the cross strut 3, and is used to discharge the air in the inner tube when the wheel set 8 rotates; The slide plate 33 is arranged horizontally, and it is slidably inst...

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 invention relates to the field of bicycle maintenance tools, in particular to a bicycle tire removing 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 take out the punctured inner tube of the tire and repair it after the tire is removed from the wheel set by using a tire warping tool. When the tire is warped, stick-shaped tools such as screwdrivers are generally used to war the tire, 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 deficiencie...
