The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

With reference to Fig. 1 ~ Fig. 6, the draw bail of motorcycle helmet face shield of the present utility model, comprise helmet body 1 and face shield 2, two side positions at described helmet body 1 are provided with base 3, the one side of described base 3 contiguous helmet bodies 1 is provided with boss 31, is provided with the installing hole 32 of perforation on described boss 31 and base 3, and ear lid 4 is installed on face shield 2, the card column 41 arranging on described ear lid 4 stretches in described installing hole 32, between described boss 31 and base 3, is formed with slideway 33, also comprise a pushing hands 5 and a stage clip 6, one end of described pushing hands 5 stretches in slideway 33, the other end stretches out described base 3, in pushing hands 5, be provided with the slotted eye 51 of the described card column 41 of stepping down, be card column 41 from outer toward interior successively through the installing hole 32 on base 3, slotted eye 51 in pushing hands 5 and the installing hole 32 on boss 31, one end of described stage clip 6 is with base 3 butts, the other end and pushing hands 5 butts and make pushing hands 5 there is all the time the trend away from described slideway 33, on base 3, be provided with restriction pushing hands 5 away from the block 34 of slideway 33, avoid pushing hands 5 to drop under the effect of stage clip 6, in described card column 41, be provided with annular groove 42, the slotted eye hole that pushing hands 5 is arranged in above annular groove 42 under the effect of stage clip 6 snaps in to described annular groove 42 along 52, promote pushing hands 5, corresponding slotted eye hole is along the described annular groove 42 of 52 disengaging.When inoperation pushing hands 5, pushing hands 5 is under the promotion of stage clip 6, slotted eye hole in pushing hands 5 is entrapped in annular groove 42 along 52, therefore card column 41 because of slotted eye hole along 52 and the clamping effect of annular groove 42 can not axially depart from installing hole 32, now, face shield 2 has just been fastened on helmet body 1, promotes face shield 2, and face shield 2 drives card columns 41 to rotate in installing hole 32 and makes relative helmet body 1 pivot joint of face shield 2, when needs are pulled down face shield 2, upwards promote pushing hands 5, pushing hands 5 overcomes the elastic force of stage clip 6, slotted eye hole in pushing hands 5 is spun off in the annular groove 42 card column 41 along 52, card column 41 just can move axially and be removed in installing hole 32, the general plastic production that adopts of face shield 2, can the width of face shield 2 be set large compared with the distance between two bases 3, after face shield 2 installations, the two ends of face shield 2 can form outside tension force, therefore as long as promote pushing hands 5, card column 41 just can eject from installing hole 32 automatically by the outside tension force of face shield 2, face shield 2 can conveniently be taken off from helmet body 1, when needs assemble face shield 2, upwards promote pushing hands 5 and overcome stage clip 6 elastic force, then the card column 41 on ear lid 4 is inserted in installing hole 32, then decontroling pushing hands 5 resets stage clip 6, slotted eye hole in pushing hands 5 snaps onto in the annular groove 42 of card column 41 along 52, what make that face shield 2 can be easy and convenient is arranged on helmet body 1, above-mentioned draw bail has been abandoned and in conventional art, by structures such as screws, has been connected the structure of face shield and helmet body, simplified greatly the draw bail between face shield 2 and helmet body 1, have convenient to disassembly, simple to operate, it is convenient to implement, the features such as low cost of manufacture.

In the present embodiment, on described base 3, be provided with plug tenon 35 and back-off 36, on described helmet body 1, be provided with the jack 11 corresponding with described plug tenon 35 and back-off 36, described base 3 is arranged on described helmet body 1 with being fixed of jack 11 by plug tenon 35, back-off 36, certainly, base 3 also can adopt the modes such as bonding or screw to be fixed on helmet body 1.

In the present embodiment, in described pushing hands 5, be provided with the bar-shaped trough 53 of the described back-off 36 of stepping down when pushing hands 5 action, back-off 36 is arranged on the front side lower position of plug tenon 35, on the groove edge of described back-off 36 and this bar-shaped trough 53, be provided with opposed projection 37, described stage clip 6 is nested with on this two projection 37.

In the present embodiment, the head of the card column 41 of ear lid 4 is made cone structure so that install, and when assembling face shield 2, card column 41 is pushed in installing hole 32, the conical surface of card column 41 heads can automatically promote that pushing hands 5 is moved and the elastic force that overcomes stage clip 6 is installed very convenient.For this reason, for its head after avoiding card column 41 to insert in installing holes 32 and helmet body 1 interfere, can on described helmet body 1, be provided with the via hole 12 of the described card column 41 of stepping down.

In the present embodiment, for avoiding described draw bail to expose, and make whole helmet structure compacter, preferably on described helmet body 1, be provided with the recess 13 of accommodating described base 3 and pushing hands 4.

Described ear lid 4 can one-body moldedly arrange with face shield 2, select in an embodiment split setting, for this reason, on described face shield 2, be provided with the through hole 21 of the described card column 41 of stepping down, on described ear lid 4, be provided with limited block 43, on face shield 2, be provided with the spacing hole 22 corresponding with described limited block 43, card column 41 snaps onto in described spacing hole 22 through the rear described limited block 43 of through hole 21, limited block 43 has limited the circumferential movement of the relative ear lid 4 of face shield 2 with arranging of spacing hole 22, avoid occurring the idle running phenomenon of the relative ear lid 4 of face shield 2 when promoting face shield 2.

The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
