Description

Improved racket frame structure

technical field

The utility model relates to the technology in the field of sports equipment rackets, in particular to an improved structure of a tennis racket frame made of carbon fiber materials. the

Background technique

As everyone knows, as shown in FIG. 1 , the well-known tennis racket is mainly composed of three parts: a head frame 10 , a triangular throat 20 and a handle 30 . In the field of tennis rackets, carbon fiber tennis rackets occupy the mainstream market due to their lighter weight. However, due to the poor impact resistance and strength of carbon fiber rackets, the rackets are easily damaged and deformed when impacted, resulting in a short service life of the racket. . the

In response to this, there are some carbon fiber racket frame hollow tubes on the market that are provided with reinforcing ribs to improve the strength of the racket. When this racket is processed, it is composed of two carbon fiber tubes stacked and composited, and two symmetrical adjacent tube walls are solidified to form Reinforcing ribs, because the traditional carbon fiber racket frame is blown to make the hollow tube expand and stick to the mold, in order to allow the gas to be evenly distributed in all parts of the racket frame, the head frame of the entire racket and the section of the triangular throat The reinforcing ribs formed have the same direction and the same number. Since the handle is formed by extending and compounding two carbon fiber tubes on the left and right sides of the triangular throat and the hollow tubes between the two are connected, the reinforcing ribs of the handle section are the triangular throat The sum of the ribs of the two carbon fiber tubes. the

As shown in Fig. 2, Fig. 3 and Fig. 4, it has shown a kind of structure of existing product, and the direction of reinforcing rib 11,12 of the section of its head frame 10 and triangular throat 20 is perpendicular to the hitting plane, and its number They are all one, and the reinforcing ribs 11, 12 divide the section of the head frame and the triangular throat into two left and right parallel hollow cavities 12, 22, wherein, the direction of the reinforcing rib 31 of the section of the handle 30 is the same as that of the above-mentioned head frame 10 and triangular throat 20, and the quantity of reinforcing rib 31 is three, and the section of handle 30 is divided into four hollow cavities 32 that are closely side by side, and there is no expansion filler in each hollow cavity. the

See Fig. 5, Fig. 6 and shown in Fig. 7 again, it has shown another kind of structure of existing product, and the direction of its reinforcing rib 11,21,31 is parallel with the hitting plane, and wherein head frame 10 and triangular throat 20 The reinforcing ribs 11 and 12 of the cross-section are one, and the cross-section of the head frame 10 and the triangular throat 20 is divided into two symmetrical hollow cavities 12 and 22, and the reinforcing ribs 31 of the cross-section of the handle 30 are three, and the handle The section of 30 is divided into four hollow cavities 32 closely stacked up and down. the

Although these two structures have the effect of improving the impact resistance and compression resistance of the racket, due to the limitation of their processing technology, the reinforcing ribs formed on the cross section of the head frame and triangular throat of the entire racket frame must have the same direction and equal number At the same time, the reinforcement ribs of the section of the handle are also determined, which means that as long as the direction and number of reinforcement ribs on the section of one of the three parts of the head frame, triangular throat or handle are determined, the other parts The direction and number of ribs in the cross-section are then determined. However, according to personal habits, racket users sometimes prefer that the direction of the reinforcing ribs of the head frame section is parallel to the hitting plane, while the direction of the reinforcing ribs of the triangular throat section is perpendicular to the hitting plane, and requires reinforcement of the head frame section. The number of ribs is different from the number of reinforcing ribs in the triangular throat section. This structure cannot be achieved for the above-mentioned prior art. In this way, the direction and number of reinforcing ribs cannot be changed arbitrarily according to the needs of customers, which is not conducive to the market. compete. the

Therefore, how to provide a racket with reinforcing ribs that are at least different in direction or number on the head frame, triangular throat and handle according to different requirements is the direction that technicians engaged in this industry need to study and improve urgently. the
