Abstract
The utility model provides a carbon fiber seat tube which comprises a carbon fiber tubular body and a plurality of metal bodies uniformly embedded on the outer wall of the carbon fiber tubular body. The carbon fiber seat tube has the benefit that the carbon fiber seat tube is more wear-resistant, and the toughness of the carbon fiber seat tube is increased.
Description
Technical field
The utility model belongs to bicycle accessories field, especially relates to a kind of carbon fiber seat pipe.
Background technology
Seat pipe is the significant points that connects vehicle seat and vehicle frame, need catch gear that it is connected with vehicle frame, after locking, rely on the friction force of its outer wall and frame tube inwall to support bicyclist's body weight, carbon fiber seat pipe is because the light feature of its quality is widely used in road cycling, existing carbon fiber seat pipe is mostly full carbon fiber structural, although this structure quality is light, but because carbon fiber is not wear-resisting, after using a period of time there is an accident for pipe fracture in easy wearing and tearing seat pipe, the fragility of carbon fiber is larger, withstands shocks and easily ruptures.Exist carbon fiber seat pipe not wear-resisting, after wearing and tearing, easily ruptures, the technical matters such as fragility is large.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of carbon fiber seat pipe, is especially suitable for the once resistance to abrasion of strong carbon fiber seat pipe.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of carbon fiber seat pipe, comprises carbon fiber tubulose body and multiple metallic object that is evenly embedded in the external wall of described carbon fiber tubulose.
Further, described metallic object is strip shape, and length is 7cm～30cm, and width is 2mm～30mm, and described metallic object at least comprises 2.
Further, described metallic object is along described carbon fiber tubulose axon to layout.
Further, described metallic object is aluminum alloy bar.
Further, described metallic object is titanium alloy bar.
Further, described metallic object is stainless steel strip.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, carbon fiber seat pipe is more wear-resisting, increase carbon fiber seat pipe toughness; Have simple in structure, the advantage such as resistance to abrasion is good, and toughness is high, safety height.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.

The specific embodiment
As shown in Figure 1, 2, a kind of carbon fiber seat of the utility model pipe, comprises carbon fiber tubulose body 1 and multiple metallic object 2 that is evenly embedded in carbon fiber tubulose body 1 outer wall; Metallic object 2 is strip shape, and length is 7cm～30cm, and width is 2mm～30mm, and metallic object 2 at least comprises 2; Metallic object 2 is axial arranged along carbon fiber tubulose body 1; Metallic object 2 is aluminum alloy bar; Metallic object 2 is titanium alloy bar; Metallic object 2 is stainless steel strip.
The working process of this example: seat pipe is that the friction force increasing between seat pipe and vehicle frame by latching device is connected with vehicle frame, when locking force is inadequate or run into larger impact, between seat pipe and vehicle frame, can produce relative sliding, this slip meeting produces wearing and tearing to carbon fiber seat pipe, carbon fiber seat tube wall attenuation easy fracture after wearing and tearing, therefore, at the outer wall embedded with metal body 2 of carbon fiber tubulose body 1, when car body is with seat pipe friction like this, rub with metallic object 2 and carbon fiber tubulose body 1 simultaneously, because the resistance to abrasion of metal is better than carbon fiber, therefore can reduce the wearing and tearing of carbon fiber seat pipe, increase the service life of carbon fiber seat pipe, in addition, during the large collision of carbon fiber fragility, easily rupture, after embedded with metal bar, increase the toughness of carbon fiber seat pipe, easy fracture not when bumping.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
