Description

Head pipe triangular opening PU for manufacturing carbon fiber bicycle frame

Technical Field

The utility model relates to the technical field of bicycles, in particular to a head pipe triangular opening PU for manufacturing a carbon fiber bicycle frame.

Background

The bicycle is a common traffic tool, and the main components of the bicycle include a frame, tires, a front fork and the like. The main parts of the frame are a head pipe, an upper pipe, a lower pipe, a seat pipe, a middle pipe, a five-way pipe, an upper fork and a lower fork. In bicycles made of various materials, the popularity of carbon fiber bicycles is gradually increased in recent years, the production stability and strength requirements are also increased, the existing PU is used in mass production, but the strength and the utilization rate of the PU are uneven, in order to better ensure the strength of a bicycle frame and the rationality of the PU in the standard design, and from the angles of designers and users, a novel PU is designed to meet the requirements of mass production, so that the productivity and the efficiency are improved. The existing head tube triangular opening PU for manufacturing the carbon fiber bicycle frame is low in productivity efficiency, poor in stability, inconvenient in carbon pasting and distributing piece, and small in effect of stabilizing the structural strength of the head tube of the frame.

Disclosure of Invention

The utility model provides a head tube triangular opening PU for manufacturing a carbon fiber bicycle frame, which is convenient for attaching a carbon cloth piece and has good stability.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a head pipe triangle opening PU for manufacturing a carbon fiber bicycle frame comprises a head pipe triangle opening PU, wherein three directions at the upper end and the lower end of the head pipe triangle opening PU are respectively provided with triangle grooves with the width of 10mm, the depth of 2mm and the height of 20 mm.

Further, the triangular grooves on the upper side and the lower side correspond to each other.

Further, the distances between every two adjacent triangular grooves are the same.

Compared with the prior art, the utility model has the advantages that: the structure of the triangular opening pu of the head pipe is changed, 3 newly added triangular grooves are vertically pasted with carbon cloth pieces up and down, so that the effect of reinforcing fixed support is achieved.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a top view of the present utility model.

As shown in the figure: 1. triangular grooves.

Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 to 2, a triangular opening PU for manufacturing a carbon fiber bicycle frame comprises a triangular opening PU for manufacturing a carbon fiber bicycle frame, and is characterized in that: three triangular grooves (1) with the width of 10mm, the depth of 2mm and the height of 20mm are formed in each of the upper end and the lower end of the triangular opening PU of the head pipe.

The triangular grooves (1) on the upper side and the lower side are corresponding, and the intervals between every two adjacent triangular grooves (1) are the same. In the description of the present utility model, it should be noted that, unless explicitly stated and limited otherwise, the term "connected" should be interpreted broadly, and for example, it may be a fixed connection, a removable connection, or an integral connection; the specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
