Detailed Description
In order to make the above features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Referring to FIG. 1
The double-end tire removing hook comprises a rod body 10, wherein two ends of the rod body are respectively provided with a bent hook part, the length of one end hook part 11 is larger than that of the other end hook part 12, and the bending degree of the other end hook part 12 is larger than that of one end hook part 11.
In this embodiment, in order to meet different requirements, the hook portions at two ends of the rod body are bent in a clockwise direction or a counterclockwise direction at the same time. Or the hook part at one end of the rod body is bent clockwise, and the hook part at the other end of the rod body is bent anticlockwise.
In this embodiment, for convenience of installation and use, the middle part of the rod body is provided with a mounting hole 13. The inner wall of the mounting hole is provided with a stop lug 14 protruding towards the center direction of the mounting hole so as to be matched with a shaft lever on the tire dismounting machine through the stop lug, and further the tire dismounting hook part is prevented from rotating during working.
In this embodiment, in order to make the structure of the double-end tire removing hook more compact, the width of the rod body gradually decreases from the middle to the two ends and starts to approach to a uniform width at the hook portions at the two ends.
In this embodiment, in order to better match with the tire removing machine, the width of the middle portion of the rod body is 30-55 mm, where the optimal width is 40mm. The width of the stop lug is 5-7 mm, wherein the optimal width is 6mm.
