Abstract

The utility model discloses a telescopic rear mudguard of a bicycle. The telescopic rear mudguard is characterized in that a mud cover comprises 3 to 6 short mud covers which are sequentially sleeved into a whole body through flanged edges in grooves on two sides of the short mud covers and are matched and fixed into a whole body through limiting pits with right triangle sections arranged in the middles of the rear parts on bottom surfaces of the short mud covers and limiting noses with corresponding shapes at the front ends of the top surfaces of the short mud covers in front of the short mud covers with the limiting pits; the short mud covers can be expanded; and the length of each short mud cover can be adjusted according to the size of a wheel of the bicycle. The telescopic rear mudguard has the advantages of good applicability and convenience in manufacture, use, storage, transportation and marketing.

Description

Bicycle concertina type rear mudguard

Technical field

The utility model relates to the attachments of a bicycle manufacturing technology, particularly a kind of bicycle concertina type rear mudguard.

Background technology

The crowd can be known, and bicycle all is provided with mudwing, and earth is splashed on one's body the cyclist when preventing from travelling.In the prior art, bicycle mudguard generally is made up of mounting ring, adjust bar and mud cover, during installation it is joined ring and is fixed on the support tube of bicycle mounting, adjusts adjust bar according to actual conditions then, makes mud cover cover wheel and just can.Existing mud cover is whole and makes, shared volume is bigger, be not easy to accumulating and sale, in addition, mud cover must be decided according to the size of cycle wheel, the mudwing that the wheel of different-diameter is equipped with is also different, and this makes troubles for production and the use of mudwing, and this is the fault of existing bicycle integral type mudwing just.

The utility model content

The purpose of this utility model is to overcome the problems referred to above that bicycle mudguard exists, and provides a kind of and folds, and can adapt to the bicycle concertina type rear mudguard of different bicycle quick sizes.

For achieving the above object, the utility model is achieved in that a kind of bicycle concertina type rear mudguard, include mounting ring, adjust bar and mud cover, it is characterized in that described mud cover is made up of 3 ~ 6 short mud covers, the most last short mud cover is connected with adjust bar, except a terminal short mud cover, the both sides of the short mud cover of all the other each pieces are to the flange that has indent, the limited pit that to have a cross-sectional plane in the middle of bottom surface, the short mud cover rear portion of each piece be right-angled triangle, its right angle face in the back, in the middle of the short mud cover front end of the top surface of each piece, be provided with a spacing plush copper that cooperates with last short mud cover limited pit, the short mud cover of each piece is socketed in the flange of last short mud cover with the flange of its both sides, the short mud cover of last piece is socketed in the flange of last short mud cover with its both sides, each short mud cover places with its spacing plush copper in the limited pit of last short mud cover and is linked in sequence together, and it is made of plastic that each lacks mud cover.

The utility model is to use like this: when needs fold, as long as each short mud cover is pushed away forward, because limited pit is very shallow, thinner short mud cover is made of plastic to have certain elasticity, under thrust, the limited pit that the spacing plush copper of the short mud cover in back is easy to break away from last short mud cover slides to bottom surface mobile being superimposed together forward along the inclined-plane, because each weak point mud cover is to connect together mutually with its both sides in-flanges, each weak point mud cover can not come off in moving process; When needs stretch this mudwing with each short mud cover toward post-tensioning, the spacing plush copper of the short mud cover of each piece is stuck in the limited pit of last short mud cover cheaply can.Because the rear end of spacing plush copper and limited pit is the right angle face, or else can move after being in contact with one another.Play good location and position-limiting action.

The beneficial effects of the utility model are as follows:

1, because mud cover of the present utility model is scalable, bring convenience for accumulating and sale.

2, the utility model can be according to the size adjustment length of cycle wheel, and applicability is wide, is conducive to make and use.

The specific embodiment

See figures.1.and.2, a kind of bicycle concertina type rear mudguard, include mounting ring 1, adjust bar 2, with mud cover 3, it is characterized in that described mud cover 3 is made up of 3 ~ 6 short mud covers 4, the most last short mud cover 4 is connected with adjust bar 2, except a terminal short mud cover 4, the both sides of all the other each short mud covers 4 of pieces to the flange 5(that has indent shown in Fig. 3 ~ 5), the limited pit 6 that to have a cross-sectional plane in the middle of bottom surface, short mud cover 4 rear portion of each piece be right-angled triangle, its right angle face in the back, in the middle of short mud cover 4 front end of the top surface of each piece, be provided with spacing plush copper 7(such as a Fig. 3 and shown in Figure 5 who cooperates with last short mud cover 4 limited pits 6), the short mud cover 4 of each piece is socketed in the flange 5 of last short mud cover 4 with the flange 5 of its both sides, the short mud cover 4 of last piece is socketed in the flange 5 of last short mud cover 4 with its both sides, each short mud cover 4 places with its spacing plush copper 7 in the limited pit 6 of last short mud cover 4 and is linked in sequence together, and it is made of plastic that each lacks mud cover 4.

When implementing, the utility model also takes following measure further perfect:

Described short mud cover 4 is 6, can improve applicability.

Below the front end of every short mud cover 4, be provided with a thrust plate 8.Short mud cover 4 is fitly stacked after folding.

Be provided with guide groove 9 in flange 5 lower inside, be provided with guiding fin 10 in the outside, it is flexible and be conducive to fix to be cheaper than short mud cover 4.
