Abstract

The utility model relates to an improved racket with a carbon fiber central tube bridged aluminum racket frame, which comprises a carbon fiber central tube, a plug and an aluminum racket frame; one end of the carbon fiber central tube is inserted with the plug; two free ends of the aluminum racket frame are respectively butted and connected with the exposing end of the plug; a long fiber mesh belt is wounded at the triangle position of butting and connecting; then, the preform body of the racket is inserted in a mold; after the heating procedures of the carbon fiber racket, all the components are integrated into a whole; the plug can improve binding strength of the carbon fiber central tube and the aluminum racket frame, which prevents the carbon fiber central tube from flattening and cracking.

Description

Pipe bridge connects the racket of aluminium frame in the carbon fiber of improvement

The utility model relates to a kind of racket, particularly relates to the racket that pipe bridge in a kind of carbon fiber of improvement connects the aluminium frame.

See also Fig. 1, shown in Figure 2, the carbon fiber racket structure of commonly using with aluminium frame, it mainly is that an end of will manage (12) in aluminium frame (11) two ends and the carbon fiber is abutted against, and be abutted against the position at this and swathe long fiber material (13), form the blank body of racket, this racket blank body is inserted in the mould again, impose high temperature and carry out thermocompression forming, its shortcoming is:

1. should manage (12) when carrying out mould heat pressure in the logical empty carbon fiber, it is abutted against the bad situation that end often has being crushed, breaks.

2. pipe (12) is abutted against the position and only swathes single long fiber material (13) in its aluminium matter frame (11) and the carbon fiber, so this position intensity is relatively poor.

In view of this, main purpose of the present utility model is to provide that pipe bridge connects the aluminium frame in a kind of carbon fiber of improvement, make to manage in the carbon fiber and be inserted with the cylinder chock plug of reserving one section emergence end in the endoporus that connects end in advance, can prevent when upper and lower mould plus-pressure not only that pipe is crushed in the carbon fiber breaks, and can improve quality, reduction fraction defective, and can strengthen and aluminium frame two free-ended bond strengths.

The purpose of this utility model is realized by following technical scheme.

Pipe bridge connects the racket of aluminium frame in a kind of carbon fiber of improvement, comprise pipe in the carbon fiber, reach an aluminium frame, its improvements are: also be provided with a chock plug, this chock plug is to be plugged on described carbon fiber one end of the central tube, and two free ends of described aluminium frame are to be abutted against mutually with the emergence end of this chock plug respectively, and the triangle portion winding long fibre ribbon that is being abutted against, again this racket blank body is inserted in the mould, through the heating fabrication schedule of carbon fiber racket, make that pipe integrally combines securely by chock plug and aluminium frame in the carbon fiber.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is an exploded perspective schematic diagram of commonly using aluminium frame racket structure.

Fig. 2 is a combination blank body schematic perspective view of commonly using aluminium frame racket structure.

Fig. 3 is an exploded perspective schematic diagram of the present utility model.

Fig. 4 is a combination schematic diagram of the present utility model.

Fig. 5 is the schematic perspective view of combination blank body of the present utility model.

See also Fig. 3 to shown in Figure 5, the utility model includes pipe (21), a chock plug (22) and aluminium frame (23) three parts in the carbon fiber, wherein:

Pipe (21) is the hollow tube of not holing in this carbon fiber, the one end is for grafting chock plug (22), two free ends (231) of aluminium frame (23) are to be abutted against mutually with the emergence end (221) of this chock plug (22), twine long fibre ribbon (24) at the triangular part that is abutted against, again this racket blank body is placed in the mould, heating fabrication schedule through existing carbon fiber racket, then finish in the carbon fiber pipe (21) and borrow chock plug (22) very to combine securely, also have difficult advantage of being split by mould holder of pipe (21) in the carbon fiber with aluminium frame (23).

In sum, pipe bridge connects the racket of aluminium frame in the carbon fiber of the utility model improvement, though very simple, but can be at the various shortcoming of commonly using carbon fiber racket structure with aluminium frame, propose the way of solution, have more progressive and practicality, meet novel patent application important document in fact.

Claims

1, pipe bridge connects the racket of aluminium frame in a kind of carbon fiber of improvement, comprise pipe in the carbon fiber, reach an aluminium frame, it is characterized in that: also be provided with a chock plug, this chock plug is to be plugged on described carbon fiber one end of the central tube, and two free ends of described aluminium frame are to be abutted against mutually with the emergence end of this chock plug respectively, and the triangle portion winding long fibre ribbon that is being abutted against, again this racket blank body is inserted in the mould, through the heating fabrication schedule of carbon fiber racket, make that pipe integrally combines securely by chock plug and aluminium frame in the carbon fiber.
