Abstract
The utility model discloses a D type shaft of a bicycle. The D type shaft comprises a D type shaft body and a locking element, wherein thread blind holes are respectively and symmetrically formed in the end surfaces of two sides of the D type shaft body; the axes of the thread blind holes and the axis of the D type shaft are collinear; the locking element comprises hexagonal bolts which are matched with the thread blind holes. By matching the thread blind holes and the hexagonal bolts, the matched thread section is effectively protected, so that stuck caused by bumping and rusting is avoided; the D type shaft of the bicycle is convenient to detach, simple in structure and low in cost.
Description
Technical field
The utility model relates to axle technical field, relates in particular to a kind of bicycle D profile shaft.
Background technique
On market, to be all generally that two ends are undertaken by outside thread attaching nut fastening for bicycle D profile shaft, and the shortcoming of this mode is: the screw thread that exposes of D profile shaft easily collides with or gets rusty, and is not possessing under dust-proof effect, stuck phenomenon just easily occurs, thereby be not easy to dismounting.
Model utility content
The utility model is mainly to solve existing technical problem in prior art, thereby provides one to have dust-proof effect, easy-off bicycle D profile shaft.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Bicycle D profile shaft of the present utility model, comprise D profile shaft body and locking element, described D profile shaft body both sides end face is the symmetrical tapped blind hole that has respectively, the mutual conllinear of axis of the axis of described tapped blind hole and described D profile shaft body, described locking element comprises hex head bolt, wherein, described tapped blind hole and hex head bolt match.
Further, between described hex head bolt and D profile shaft body, be also provided with rubber washer, described rubber washer be shaped as circle, and be located in the threaded end of described hex head bolt.
Further, the length of described hex head bolt is less than the degree of depth of described tapped blind hole, and the size of described hex head bolt and tapped blind hole is M8.
Compared with prior art, the utility model has the advantage of: be used in combination by the tapped blind hole and the hex head bolt that arrange on D profile shaft body, effectively protected the thread section coordinating; avoid colliding with and getting rusty the stuck phenomenon causing; for convenience detach, and it is simple in structure, and with low cost.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of bicycle D profile shaft of the present utility model;
Fig. 2 is the structural representation of the D profile shaft body of bicycle D profile shaft of the present utility model;
Fig. 3 is the structural representation of the hex head bolt of bicycle D profile shaft of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1-3, bicycle D profile shaft of the present utility model, comprise D profile shaft body 1 and locking element, D profile shaft body 1 both sides end face is the symmetrical tapped blind hole 11 that has respectively, the mutual conllinear of axis of the axis of tapped blind hole 11 and D profile shaft body 1, can add man-hour at part so convenient, and be convenient to the installation and removal of locking element.Locking element comprises hex head bolt 2, and wherein, tapped blind hole 11 and hex head bolt 2 match.
Concrete, between hex head bolt 2 and D profile shaft body 1, be also provided with rubber washer 3, rubber washer 3 be shaped as circle, and be located in the threaded end of hex head bolt 2.Rubber washer 3 has certain anti-loosing effect, and can make hex head bolt 2 and tapped blind hole 11 fit tightly, and has indirectly played dustproof effect.Preferably, the length of hex head bolt 2 is less than the degree of depth of tapped blind hole 11, just can reach fastening effect.The size of hex head bolt 2 and tapped blind hole 11 goes to set according to the carrying situation of the size of D profile shaft and actual demand, and in the present embodiment, preferred, the size of hex head bolt 2 and tapped blind hole 11 is M8.
The utility model is used in combination by the tapped blind hole and the hex head bolt that arrange on D profile shaft body, has effectively protected the thread section coordinating, and has avoided colliding with and getting rusty the stuck phenomenon causing, for convenience detach, and it is simple in structure, with low cost.
Above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
