Abstract

The utility model provides a rear wheel shock-absorber for a bicycle, which is a shock-absorbing device additionally arranged on the part of the triangulation point after a frame under the conditions that the original structure of the bicycle can be protected effectively and the stress is unchanged. The utility model has the advantages of flexible bounce, durability, beautiful appearance, and self-protection after overweight. Particularly the outstanding appearance shape is harmoniously combined with the entire bicycle. The utility model substantially enhances the comfort for the bicycle, and simultaneously, the noble and fashionable appearance for the bicycle can be further added. The appearance and the use of the utility model promote the shock absorbing bicycle to develop towards a mature and normative direction.

Description

The bicycle rear bumper

The utility model relates to the development and the raising in bicycle field.

Bicycle style in the market is various, beautiful in colour, yet these cars do not obtain solution fundamentally all the time aspect traveling comfort.In this year along with the needs of bicycle development, though international, the domestic bicycle that has indivedual producers to release several band shock absorption devices is not ideal enough mostly, or the resulting structure of loss bicycle, or reduce its impregnability practicality, especially the living standard from the people has certain distance.

It is low that the utility model purpose is to release a kind of cost, and structural refinement is suitable for popularizing the high-tension bumper of producing.

The bumper that the utility model is released, be further to study and improve design-calculated on the basis of several patents before I am own (behind a kind of bicycle, the universal bicycle shock-absorbing pitch, universal automatic shock-proof device) with damping device, the current sleeve type bicycle rear wheel shock-absorbing utensil of releasing has structural refinement, firm flexible, process advantages such as easy, leading advance is not only arranged, and more pad has been decided the basis of damping car to the regularization development.

Be illustrated below in conjunction with accompanying drawing:

Fig. 1: be that folder is looked intention by connecting-type sleeve bumper;

Fig. 2: the cutaway view that is Fig. 1;

Fig. 3: be that grafting jacket tube bumper is looked intention.

Shown in the figure: 1 sliding cylinder, 2 springs, 3 axletree holes, 4 stationary magazine creels, 5 special-shaped pads, 6 slideways, 7 are withheld arm behind tube, 8 vehicle frames, 9 screw holes, 10 plugs.

The current bicycle rear bumper of releasing of the utility model has disclosed two kinds of versions of a kind of principle simultaneously.Shown in Figure 1: as to be that folder is looked intention by the bicycle rear bumper of connecting-type, it is characterized in that: sliding cylinder (1) built-in spring (2), lower, transverse is established an axletree hole (3), be contained in the fixing stationary magazine creel of vehicle frame in (4) stationary magazine creel both sides stay the slideway (6) of establishing axletree abnormity pad (5), turn round from top and cover spring by withholding tube (7), finish damping.Its connection features is the side at stationary magazine creel, the midway location of two slideways, establish a pin greater than vehicle frame after arm (8) diameter upright to groove, vehicle frame arm Vee formation position, one and groove bonded assembly vertical surface are caused in also upright downward gulf, snap in groove and fix with screw.

Fig. 2 cuts open figure under Fig. 1 axletree position, is to show the bearing fit of bright abnormity pad and the fixed form of bumper and vehicle frame.

Fig. 3 is that grafting type bicycle rear bumper is looked intention, the tube of withholding that it is characterized in that top is lived spring from the outside knob clinching of stationary magazine creel, connecting to ground is midway location at two slideways of stationary magazine creel, on divide into two plugs and directly insert in the back chain stay and the breeches pipe that retreads and fix by screw.

The bicycle rear bumper that the utility model is released; be effectively to protect the bicycle original design; under the stressed unmodified condition; at the local a kind of shock absorption device set up of vehicle frame Vee formation point, this device spring flexibly, and is firm attractive in appearance; energy self-protection after overweight; especially Tu Chu outward appearance and car load have constituted combining of coordinating, it set up the traveling comfort that has not only increased substantially bicycle, more increased the luxurious of bicycle and epoch outward appearance.The release of this bumper will promote damping bicycle to develop towards more ripe, more normalized road with use.

Claims

1, bicycle rear bumper is characterized in that by stationary magazine creel, sliding cylinder, withholds tube, inner spring four parts and cooperate and to constitute.

2, bicycle rear bumper according to claim 1, it is characterized in that: sliding cylinder built-in spring, lower, transverse are established an axletree hole, are contained in the stationary magazine creel of fixing with vehicle frame, the slideway of establishing axletree abnormity pad is stayed in the stationary magazine creel both sides, turns round from top and covers spring by withholding tube.
