Abstract

The utility model relates to a pipe fitting structure, its pipe base body are applied to bicycle seat pipe, handlebar hand or frame etc. and the outer pipe wall of pipe base body is equipped with the spiral slot, with the average dispersion of the atress of pipe base body, and locates the spiral slot of outer pipe wall via the spiral ring, can lift the whole elasticity of pipe base body to reach the efficiency that the whole atress is average and the atress buffering nature is good.

Description

Fitting structure

Technical field

This creation relates to a kind of fitting structure, especially relates to a kind of fitting structure of bicycle tube body structure art.

Background technology

In currently available technology, bicycle tube body as shown in Figure 7,8, the surface of its body 20 is level and smooth shape or is provided with circular groove groove, and the rigidity of body of surface in level and smooth shape and intensity higher, in addition, the body being provided with circular groove groove can utilize the dispersion of circular groove groove stressed, but it still has following point existence:

Overall stressed inequality: the surface of its body be level and smooth shape or is provided with circular groove groove, when body is stressed, surface is level and smooth shape or the body establishing circular groove groove, and it is stressed is concentrated in single forced position or single circular groove groove place, therefore its overall stressed inequality.

Stressed resiliency is poor: the surface of its body is level and smooth shape or is provided with circular groove groove, when body is stressed, surface is level and smooth shape or the body establishing circular groove groove, it is stressed is concentrated in single forced position or single circular groove groove place, cannot by the force dispersion of entirety, reduce the integral, flexible of body, therefore its stressed resiliency is poor.

Summary of the invention

In view of the problems referred to above that prior art exists, problem to be solved in the utility model is, provides a kind of fitting structure, solves the stressed inequality of entirety of bicycle tube body and the problem of stressed resiliency difference.

For solving the problem, the utility model provides a kind of fitting structure, and it comprises a pipe matrix, an outer tube wall is provided with outside this pipe matrix, be provided with an inner tubal wall inside this pipe matrix, and this outer tube wall perficial helical is provided with a spiral grooves, this spiral grooves is provided with a bottom land.

As preferably, this bottom land is plane setting.

As preferably, this bottom land is that circular arc planar is arranged.

The bottom land of fitting structure of the present utility model is plane or circular arc planar is arranged, its pipe matrix is applied to bicycle saddle tube, handlebar or vehicle frame etc., by spiral grooves set by the outer tube wall of pipe matrix, the mean forced of pipe matrix is disperseed, and the spiral grooves of outer tube wall is located at via helical ring, can the integral, flexible of raising pipe matrix, to reach overall mean forced and the good effect of stressed resiliency.

Detailed description of the invention

In order to understand structure of the present utility model further, feature and other objects, existing preferred embodiment is accompanied by graphic being described in detail as follows, but the embodiment illustrated by this legend is for explanations, is not be unique restriction of patent application.

Please refer to shown in Fig. 1 to Fig. 4, be the stereoscopic-state of this creation fitting structure, to be applied to a bottom land for pipe spiral grooves be that to be applied to a bottom land for pipe spiral grooves be arc surface state reference map for flat state and the second using state for side-looking state, the first using state, it comprises: a pipe matrix 10, an outer tube wall 11 is provided with outside this pipe matrix 10, and inside pipe matrix 10, be provided with an inner tubal wall 12, and outer tube wall 11 perficial helical is provided with a spiral grooves 110, this spiral grooves 110 is provided with a bottom land 110A, and bottom land 110A is plane or circular arc planar is arranged;

Fitting structure of the present utility model is completed by the cooperation of said structure.

Please refer to shown in Fig. 2 to Fig. 6, it is the side-looking state of the utility model fitting structure, it is flat state that first using state is applied to a bottom land for pipe spiral grooves, it is arc surface state that second using state is applied to a bottom land for pipe spiral grooves, 3rd using state is applied to handlebar state and the 4th using state is applied to frame state reference diagram, its pipe matrix 10 is applied to bicycle saddle tube, handlebar or vehicle frame etc., by spiral grooves 110 set by the outer tube wall 11 of pipe matrix 10, the mean forced of pipe matrix 10 is disperseed, and the spiral grooves 110 of outer tube wall 11 is located at via helical ring, the integral, flexible of energy raising pipe matrix 10, to reach overall mean forced and the good effect of stressed resiliency.

Now advantage of the present utility model is discussed below:

1. overall mean forced: spiral grooves set by the outer tube wall of its pipe matrix, disperses the mean forced of pipe matrix, therefore its overall mean forced.

2. stressed resiliency is good: the spiral grooves of outer tube wall is located at by its helical ring, the integral, flexible of raising pipe matrix, therefore its stressed resiliency is good.
