Abstract

The utility model relates to a bicycle pipe piece structure. The inner structure of the bicycle tubular structure comprises reinforcing ribs and a wire groove or a wire stopping housing groove. The utility model has the advantages of the inner of a pipe piece comprises a reinforcing rib structure, which enables the strength of the pipe piece to be increased and the weight to be reduced, and the appearance of the whole bicycle can not be influenced; the inner of the pipe piece comprises the wire groove or the wire stopping housing groove, which enables a braking wire and a speed change wire to be ran inside. Under the precondition of no influence of the use effect of the whole bicycle, the appearance is changed, and thus the whole bicycle looks compact. The pipe wires are not arranged outside, and the happened probability of other use accidents can be avoided.

Description

The bicycle pipe part structure

The utility model relates to a kind of bicycle pipe part structure.

Bicycle is a requisite traffic amusement and recreation instrument in people's daily life, continuous variation along with market, the customer also improves constantly the bicycle demand, this just requires no matter the designer processes the choice structure moulding at pipe fitting, appearance design still is all many-sides such as complete vehicle weight, all must constantly pursue, rationally, safety, easy for operation or the like.Some car is pursued in light weight, and some car is pursued the slightly spacious of structure again in addition.

Present bicycle pipe part, inside is blank pipe, and the thick then weight of body strengthens, and body book then insufficient strength and brake cable, shift cable designs outside body, is subject to outside destroy, and outward appearance is also succinct inadequately, attractive in appearance.

The purpose of this utility model then is the problem that exists at above-mentioned prior art, has designed the bicycle pipe part structure that a kind of inner structure contains reinforcing steel, metallic channel or principal vertical line shell groove.

The purpose of this utility model can reach by following measure:

A kind of bicycle pipe part structure is characterized in that:

There is reinforcing steel 21 a, pipe fitting 20 inside;

There are metallic channel 22 or principal vertical line shell groove 23 in b, pipe fitting 20 inside.

The utility model has following advantage compared to existing technology:

1, the utility model contains the reinforcing steel structure in pipe fitting inside, can increase its pipe fitting intensity, reduces its weight, for the car load outward appearance without any influence.

2, the utility model contains metallic channel or principal vertical line shell groove in pipe fitting inside, can make brake cable, shift cable walk inside, under the prerequisite that does not influence the car load result of use, change its outward appearance, make car load seem succinct and spool not in the outside, avoid the possibility of other use accident generation.

Fig. 1 is that the utility model includes one of reinforcing steel fitting structure generalized section.

Fig. 2 be the utility model include reinforcing steel fitting structure generalized section two.

Fig. 3 be the utility model include reinforcing steel fitting structure generalized section three.

Fig. 4 is that the utility model includes metallic channel fitting structure generalized section.

Fig. 5 is that the utility model includes principal vertical line shell barrel spare structural profile scheme drawing.

Fig. 6 is that the utility model includes metallic channel, principal vertical line shell barrel spare structural profile scheme drawing.

Fig. 7 is that the utility model includes reinforcing steel, metallic channel (principal vertical line shell groove) fitting structure generalized section.

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

The utility model design-calculated pipe fitting 20, several reinforcing steel structures of its inner increase, the reinforcing steel 21 (as shown in Figure 1) of useful arc, linear reinforcing steel 21 (as shown in Figure 2), semi-round reinforcing steel 21 (as shown in Figure 3) etc., can be one or more, increase its pipe fitting 20 intensity, can reduce its weight, for the car load outward appearance without any influence.

As Fig. 4, Fig. 5, shown in Figure 6, when its pipe fitting 20 inside have one or more metallic channel 22 or principal vertical line shell groove 23 to be used for managing pipe fitting on the bicycle, brake cable, shift cable can directly be passed from pipe fitting 20 inside, like this from can't see spool in appearance, make car load seem succinct, and spool is avoided the possibility of other use accident generation not in the outside.

As shown in Figure 7, to contain reinforcing steel 21, metallic channel 22 or principal vertical line shell groove 23 are the designs of a kind of more novel pipe fitting to pipe fitting 20 inner structures.

Claims

1, a kind of bicycle pipe part structure is characterized in that:

There is reinforcing steel (21) a, pipe fitting (20) inside;
