Description

The fixed sturcture of shelf behind the bicycle

Technical field

The utility model relates to a kind of bicycle luggage carrier, and is more detailed, is meant a kind of applicable to shelf structure behind the bicycle of various different tube diameters bench hassock tubes especially.

Background technology

Press, the shelf of bicycle are numerous, have and be fixed in the fixed type shelf on the pipe behind flower-drum axle center and the vehicle frame, the shelf that are fixed on the bench hassock tube are also arranged, be a kind of shelf structure that is fixed on the bench hassock tube as shown in Figure 6, mainly be to be provided with a locking body at the shelf front end, one end of this locking body is the end of a mobile of being pivoted, and the other end of locking body is in conjunction with a fixed body, mobile's other end then is provided with a broken groove corresponding to locking body, can supply the ccontaining of fixed body, can make locking body and movable the combination fast be fixed in bench hassock tube by the transfer of fixed body.

Only, these shelf are owing to be that the locking body that is pivoted by two-phase mat one fixed body, is a quick detach with mobile, and packing is at bench hassock tube, though can reach quick assembling purpose, so, fixed body, quick detach expose to have a strong impact on integral aesthetic property in the junction; Hereat, the inventor is because bicycle luggage carrier at present commonly used, still have improved place in the use, so just be engaged in the production and marketing experience for many years of bicycle Related product, and relevant issues at present bicycle luggage carrier existence, through repeatedly improve with test after, create a kind of being applicable to finally and have shelf fixed sturcture behind the bicycle of aesthetic property on the various different tube diameters bench hassock tubes again.

Summary of the invention

Main purpose of the present utility model is to provide the fixed sturcture of shelf behind a kind of bicycle, to improve the installation applicability of product.

Secondary objective of the present utility model is to provide the fixed sturcture of shelf behind a kind of bicycle, and tool is simple to operate has the effect of aesthetic property again.

In order to achieve the above object, the utility model proposes the fixed sturcture of shelf behind a kind of bicycle, these shelf mainly are to be combined with bench hassock tube by a shelf pipe front end that is provided with bolster to fix, it wherein in the pipe of this shelf pipe front end the axle bed that is equipped with a binding one collar, force axle bed to produce axial displacement by a closure again, by this, collar can be packed on the bench hassock tube by interlock.

The fixed sturcture of shelf behind the bicycle provided by the utility model, because the bore of collar can be done the adjusting of longitudinal travel arbitrarily, so on the bench hassock tube applicable to various different tube diameters, moving via bolt lock again with after axle bed forms the nut that the inclined-plane contact, can force with the collar longitudinal travel of axle bed binding shelf are tightened and fix or loosen on bench hassock tube.

Can be as for later-model other characteristics of this reality in cooperating the following drawings further to understand.

The specific embodiment

See also Fig. 1～Fig. 5, shown in the figure is the structure of the selected a kind of embodiment of the utility model, and this only for the usefulness of explanation, is not subjected to the restriction of this kind structure in patent application.

The fixed sturcture of shelf behind a kind of bicycle of the utility model, these shelf mainly are to be combined with bench hassock tube 3 by shelf pipe 2 front ends that are provided with bolster 1 to fix, it wherein in extension 20 pipes of these shelf pipe 2 front ends the axle bed 5 that is equipped with a binding one collar 4, these axle bed 5 front end both sides are the concave faces 51 that are formed with embedding post 510, can collude for collar 4 and put binding, on the axle bed 5 and be through with one vertically to accommodation space 52, these accommodation space 52 both sides inwalls are extruded with symmetry shape and preceding rim 5201 forms gradually the upwards protruding retaining wall 520 of squint, the collar 4 of this axle bed 5 leading edges binding is to have the two open limits of extending pivot ears 41 in addition, pivot ear 41 is provided with the perforation 410 of corresponding axle bed 5 front end concave faces 51 embedded posts 510, just can collude on the embedding post 510 that places axle bed 5 leading edge concave faces 51, and make this collar 4 can expose outside the mouth of pipe place of bench hassock tube 3, and shelf pipe 2 respectively is provided with a through hole 21 with respect to the upper and lower side of axle bed 5 accommodation spaces 52,22, can run through axle bed 5 lock knots for one group of closure 6, wherein the through hole 21 proper bolt 61 tooth bar portions 610 that hold in the closure 6 in upper end stretch through, the nut 62 that lower end through hole 22 then can hold in the closure 6 stretches through, this nut 62 is the cuboids that have pushing face-drawing 620 for one side in present embodiment, make the pushing face-drawing 620 of this nut 62 just can be resisted against the gradually preceding rim 5201 of squint upwards of axle bed 5 accommodation spaces 52 protruding retaining walls 520, and when turn bolt 61, should can form the inclined-plane with the preceding rim 5201 of axle bed 5 accommodation spaces 52 protruding retaining wall 520 squints via its pushing face-drawing 620 with its nut that screws togather 62 contacts, and force axle bed 5 to produce axial displacement and then the 4 synchronous starts of interlock collar.

It more than is the general introduction of structure, position and the interconnected relationship thereof of each member of the utility model; Then, again with the action of each assembly of the utility model and expect the effect statement as the back of reaching:

Please cooperate and consult Fig. 2～shown in Figure 5, when the utility model utilizes its collar 4 to be placed on bench hassock tube 3, because the bore of collar 4 can be done the adjusting of longitudinal travel arbitrarily, so on the applicable bench hassock tube 3 that is placed on various different tube diameters, the 3a, after moving the nut 62 that contacts with axle bed 5 formation inclined-planes via bolt 61 locks again, can force collar 4 longitudinal travels that link with axle bed 5, and tighten shelf fixing or loosen on bench hassock tube 3.

The mouth of pipe that it should be noted that above-mentioned shelf pipe 2 makes the better and unlikely bench hassock tube 3 that crushes of the intensity of tightening vertically to being set as slightly inside arc concavity 23.
