Drawings

Other features, objects and advantages of the utility model will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

FIG. 1 is a schematic view of a wheel bolt for easy tightening according to the present invention;

fig. 2 is a schematic cross-sectional view of a dual nut.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1 and 2, the present invention provides a wheel bolt with easy tightening, which comprises: the structure of the double-screw nut comprises a screw rod 1, wherein one end of the screw rod 1 is provided with a fixed seat 2, the other end of the screw rod 1 is in threaded connection with a double-screw nut 3, the double-screw nut 3 comprises an inner screw nut 301, an outer screw sleeve 302 and a limiting seat 303, the inner screw nut 301 is arranged at the upper end of the limiting seat 303, the outer screw sleeve 302 is sleeved on the outer wall of the inner screw nut 301, an inner thread groove 304 which penetrates out of the limiting seat 303 is arranged at the bottom of the inner screw nut 301, a rotating rod 305 is rotatably arranged at the top of the inner screw nut 301, a movable cavity 306 which corresponds to the rotating rod 305 is arranged inside the inner screw nut 301, the lower part of the rotating rod 305 is in threaded connection with a transmission sleeve 307, a clamping block 308 is arranged at the left end and the right end of the movable cavity 306 in a sliding manner, the double-screw rod 309 further comprises two hinge rods 309, one end of each hinge rod is in hinged connection with the corresponding clamping block 308, the other end of the transmission sleeve 307, the clamping block 308 penetrates out of the inner screw nut 301 and is embedded into the inner wall of the outer screw sleeve 302, the inner wall of the outer sleeve 302 is provided with a clamping groove 310 corresponding to the clamping block 308, the inner nut 301 and the outer sleeve 302 are both in a regular hexagon structure, the inner nut 301 and the limiting seat 303 are in an integrated structure, and the inner thread groove 304 is in threaded connection with the screw rod 1.
