Description

Improved bicycle parking stand

The utility model belongs to a kind of bicycle parking bracing or strutting arrangement, particularly applicable to any different automobile types bicycle use.

The hack lever of existing bicycle parking rack all adopts regular length, can't satisfy bicycle rider's user demand, as, on jolt uneven road surface or tilted road surface and mountain pass, this hack lever must have suitable collapsing length, could support car body more reposefully and be easy to put, moreover the wheel of different automobile types bicycle footpath is not of uniform size, as 24 cun, 26 cun, 28 cun etc., must use the hack lever of different length can be supporting to the bicycle in difference wheel footpath, thereby its commonality be poor.

The purpose of this utility model is present bicycle parking rack is improved, and a kind of follow-on bicycle parking rack is provided, to adapt to different road surfaces and the parked usefulness of putting of different wheel footpath bicycles.

Major technique measure of the present utility model is as follows: a kind of improved type bicycle parking rack, has a permanent seat, this permanent seat is locked in the vehicle body frame inclined tube, the intrinsic hollow sleeve of permanent seat hypomere pivot, sleeve pipe is provided with microscler cylindrical void and reaches at least 2 to deciding the hole, the mast epimere that supports bicycle is inserted in the sleeve pipe, mast top has a countersunk head hole slot, embed a wedge in the countersunk head hole slot, the lateral surface of wedge is a jag, and the end face central authorities of jag establish a screw, and the medial surface of wedge is an inserting column, establish a spring on the inserting column, outside of sleeve is provided with a navigation button, and these navigation button central authorities are provided with a fish eyelet that runs through, and is provided with a prominent bar at it to deciding side, screw passes spring, fish eyelet and with wedge on screwhole spiro bonding.

The utility model is simple in structure, makes easily, can adapt to the parked usefulness of putting of bicycle in various different road surfaces situations and various different wheels footpath.

Fig. 3 is a navigation button location fixing state cutaway view

Fig. 4 is that navigation button is state cutaway view in the displacement

Below in conjunction with accompanying drawing the utility model is described in detail:

See also Fig. 1,2, a kind of improved type bicycle parking rack, has a permanent seat, permanent seat is locked in the vehicle body frame inclined tube, the intrinsic hollow sleeve 2 of permanent seat stage casing pivot, sleeve pipe 2 is provided with microscler cylindrical void 21 and reaches at least 2 to deciding hole 22, mast 3 epimeres that support bicycle are inserted in the sleeve pipe 2, mast 3 tops have a countersunk head hole slot 31, embed a wedge 4 in the countersunk head hole slot 31, wedge 4 lateral surfaces are jag 41, and the end face central authorities of jag 41 are provided with a screw 411, wedge 4 medial surfaces are an inserting column 42, establish a spring 43 on the inserting column 42, sleeve pipe 2 outsides are provided with a navigation button 6, and navigation button 6 central authorities establish a fish eyelet that runs through 61, be provided with a prominent bar 63 at it to deciding side 62, screw 5 is worn diameter spring 51, fish eyelet 61 and screwing togather with screw 411.

See also Fig. 3, decide hole 22 when supporting on navigation button 6 and the sleeve pipe 2 and be horizontal when deciding state, give prominence to deciding hole 22 due to supporting of sleeve pipe 2 because of the pushing and pressing that are subjected to spring 43 fixed end of supporting of wedge 4, simultaneously, navigation button 6 is horizontal shape because of supporting the prominent bar 63 of deciding side 62, therefore should prominent bar 63 also prominent bar 63 is horizontal tightly to be fastened on to deciding 22 outsides, hole because of the pushing and pressing that are subjected to screw 5 and spring 51 make, thereby make mast 3 and sleeve pipe 2 be positioning states.

See also Fig. 4, when need are adjusted the collapsing length of mast 3, then need earlier horizontal navigation button 6 to be threaded to vertical direction, the application of force compresses navigation button 6 so that the jag 41 of wedge 4 is released to deciding hole 22 slightly, the prominent bar of heavy simultaneously microscler cylindrical void 21 of inserting sleeve pipe 2 then can be along the direction guiding of microscler cylindrical void 21 after hole 22 is decided in selected suitable supporting, and the turn navigation button 6 of loosing one's grip again makes its horizontal getting final product.
