In order to address the above problem, the inventor has designed the expansion sleeve type connecting structure, has solved the dismounting inconvenience and has caused parts damages and security incident easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of expansion sleeve type connecting structure, axle hole matches with axle, it is characterized in that between described axle and axle hole, being provided with a swelling cover that tapering arranged, the swelling cover cooperates with the axle hole that is provided with corresponding tapering, and the swelling cover is connected by coupling with wheel.Can be in two ways fixedly swelling cover and wheel shaft hole body, a kind of is the swelling cover that adopts flanged structure, be fixed by bolts to again on the wheel shaft hole body, so just fixed, be to adopt the not swelling cover of flanged mechanism in addition, Cock screw be housed, fixed expansion set and wheel shaft hole body at the sidepiece of wheel shaft hole body, take all factors into consideration the convenience of processing and operation, take the former means of fixation.
As preferably, be that a tapering is 1: 40 to 1: 10 a face at the circumferential surface of described swelling cover, flange arrangement is arranged on it, described coupling is a bolt, the swelling cover connects by some bolts and axle hole sports association.The inventor also has analysis of science according to the situation of reality and the experience of design accumulation, and the tapering of selection is 1: 20.
As preferably, the circumferential surface of described swelling cover is that a tapering is 1: 40 to 1: 10 a face, and described coupling is a Cock screw, and the side of wheel shaft hole body is provided with this Cock screw, fixedly the swelling cover.
As preferably, the endoporus of described swelling cover with spool match, link by flat key.
As preferably, described wheel construction is a spoke structure, and the counterface of swelling cover and wheel shaft hole body is provided with protective housing outward, the edge of protective housing aligns substantially with wheel shaft hole body edge, bolt evenly distributes along wheel shaft hole body end face in protective housing, has fixing bolt to make protective housing and axle head connect.
As preferably, described wheel construction is the web-type structure, and the counterface of swelling cover and wheel shaft hole body is provided with protective housing outward, and bolt evenly distributes along wheel shaft hole body end face in protective housing, has fixing bolt to make protective housing and axle head connect.
The beneficial effects of the utility model are: reasonable in design, easy to assembly, and solved and cooperated too tight or too loose problem, go back the convenient for maintaining dismounting, solve the wheel dress, torn inconvenient problem open, also eliminated potential safety hazard simultaneously.
