Description

A kind of bicycle folding structure

Technical field

It the utility model is related to a kind of bicycle folding structure.

Background technology

Bicycle just has become the most common vehicles in life since the 80s and 90s, but with living standard Continuous pursuit to life of raising and people, battery truck slowly instead of effect of the bicycle in society, with technology Development single structure and the bicycle of simple function much can not meet existing consumer demand.

Existing bicycle even electric bicycle all uses folding structure, ordinary bicycle to be reduced after folding and deposited The space of storage is convenient to deposit, and electric bicycle then not only facilitates storage and due to the continuous innovation of technology, new type electric bicycle Can be a series of power supply apparatus such as battery and relevant connection line concealing in master link, the structure of folding can be installed conveniently And maintenance, but existing foldable structure all as shown in figure 1, using spring clip 3 clamp bicycle left end 1 and right-hand member 2, Click and rotate to an angle could open again, dismounting is cumbersome and stress used is corresponded to and buckled in this spring clip, very It is easily damaged, service life is not grown.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of simple in construction, simple operation, convenient disassembly, safely may be used By the bicycle folding structure grown with service life.

To solve the above problems, the utility model adopts the following technical scheme that：

A kind of bicycle folding structure, including the first end cap, the second end cap, lock nut, snap ring, first end cap Lower end is rotatably connected with the second end cap, and the second end cap centre position is fixed with retainer ring, the end of the lock nut Axle is fixed with, the end of the axle is fixed with limiting plate and axle sleeve, and the snap ring is threaded in axle periphery, the shaft end The axle sleeve in portion is fixed in retainer ring, and annular groove is also distributed with the top of first end cap and the second end cap, the snap ring Lower end is fastened on annular groove, make the first end cap and the second end cap is relatively fixed setting, bottom in annular groove on second end cap End be further fixed on clamp, be also distributed on the excircle of the snap ring it is jagged, the clamp be buckled on breach realize it is relatively solid It is fixed.

Preferably, the diameter of the limiting plate is more than the diameter of axle sleeve, when the axle sleeve is threadedly coupled with retainer ring, Limitation axle sleeve persistently rotates downwards and damages lock nut.

Preferably, first end cap and the second end cap are hollow-core construction, it is the end of cycle frame, centre is placed Some power lines or electrical part.

The beneficial effects of the utility model are：A kind of bicycle folding structure of the utility model, tied relative to existing fold For structure, axle sleeve and clamp are fixed with by one end of the axle on lock nut on the first end cap and the second end cap, recycled The snap ring being threadedly coupled on lock nut excircle, which blocks the first end cap and the annular groove of the second end upper end, makes the first end cap and Two end caps are relatively fixed, and operation is more convenient, and dismounting fast and safely, while disperses external force using the spacing of snap ring, are effectively protected Protect the service life of this structure.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.

Refering to shown in Fig. 1 to Fig. 8, a kind of bicycle folding structure, including the first end cap 5, the second end cap 6, lock nut 4th, snap ring 7, the lower end of first end cap 5 are rotatably connected with the second end cap 6, and the centre position of the second end cap 6 is fixed with Retainer ring 10, the end of the lock nut 4 are fixed with axle 14, and the end of the axle 14 is fixed with limiting plate 8 and axle sleeve 9, institute State snap ring 7 and be threaded in the periphery of axle 14, the axle sleeve 9 of the end of axle 14 is fixed in retainer ring 10, the first end Annular groove 11 is also distributed with the top of the end cap 6 of lid 5 and second, and the lower end of the snap ring 7 is fastened on annular groove 11, makes first end The end cap 6 of lid 5 and second is relatively fixed setting, and bottom is further fixed on clamp 12, the card in annular groove 11 on second end cap 6 Jagged 13 are also distributed on the excircle of ring 7, the clamp 12 is buckled in realization on breach 13 and is relatively fixed.

The diameter of the limiting plate 8 is more than the diameter of axle sleeve 9, when the axle sleeve 9 is fixedly connected with retainer ring 10, limits Snap ring 7 is lasting downwards to be rotated.

The end cap 6 of first end cap 5 and second is hollow-core construction, is the end of cycle frame, and some electricity are placed in centre Source line or electrical part.

In the present embodiment, the first end cap 5 and the second end cap 6 for cycle frame the end He of left end 1 as shown in Figure 1 One end of right-hand member 2, the first end cap 5 and the second end cap 6 is mutually rotatablely connected, and the top of the first end cap 5 and the second end cap 6 is all provided with It is equipped with annular groove 11 and is encircled into circular trough body structure, the centre position of the second end cap 6 is fixed with retainer ring 10, lock nut 4 Can only be by rotating clockwise or counterclockwise, but not relative to being moved down on the first end cap 5 and the second end cap 6 when work Dynamic, the endoporus of snap ring 7 has tooth line, and the excircle of axle 14 also has tooth line and has tooth line to be connected with the endoporus of snap ring 7, and operation is rotation lock Tight nut 4, lock nut 4 rotates with moving axis 14, because axle 14 and snap ring 7 are threadedly coupled, meanwhile, on the excircle of snap ring 7 also Jagged 13 are distributed, clamp 12 is buckled in realization on breach 13 and is relatively fixed, and can move up and down snap ring 7, but not original place Rotate, when axle 14 rotates, snap ring 7 is blocked by clamp 12 and not rotated, can only be with the tooth line or screw thread on axle 14 above and below It is mobile, as shown in figure 5, snap ring 7 up, unclamps the annular groove 11 of vehicle frame front and rear part when folding, during cycling, snap ring 7 down, lock The firmly annular groove 11 of vehicle frame front and rear part.

Similarly, this foldable structure can also be with any body of rod of bicycle or on vertical and other conventional parts, together Sample realizes identical effect.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any change or replacement expected without creative work, it should all cover and be defined in scope of protection of the utility model.
