Embodiment 1

[0023] Embodiment 1: the repair method of a kind of badminton racket frame of the present invention, comprises the following steps:

[0024] S1: Use an electric drill to clean the internal fillers on both sides of the fracture at the fracture of the racket frame, and use an angle grinder to grind the section and the inner wall of the racket frame to make it suitable for glue coating; the length of the cleaned internal filler is on both sides of the fracture The distances are 1.5 threading hole pitches respectively, that is, the total length is 3 threading hole pitches;

[0025] S2: Mix the adhesive glue according to the existing glue mixing method; in this example, the planting glue is used;

[0026] S3: Prepare a pre-filled carbon fiber sheet with mesopores, the specific steps are:

[0027] A1: Select a carbon fiber sheet suitable for the length of the racket frame polished, the thickness of the carbon fiber sheet selected in this example is 0.5mm, and 3 pieces are used;

...

Embodiment 2

[0036] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in this embodiment, the length of cleaning the internal filler is 1.3 distances between the threading holes on both sides of the fracture, which can also make the repaired racket frame firm. In this example, glue is used for bonding.

Embodiment 3

[0037] Embodiment 3: The difference between this example and Embodiment 1 is that in this example, the length of cleaning the internal filler is respectively 1.2 and 1.5 distances between the threading holes on both sides of the fracture, and the total length is 2.8 threading holes distance, also can make the racket frame after repairing firm.

Abstract

The invention discloses a repairing method of a badminton racket frame, and belongs to the technical field of repairing of rackets. Specifically, the repairing method comprises the following steps: S1, cleaning internal filler in fractures of the racket frame, and implementing fracture surface and inner wall grinding; S2, mixing a steel bar planted adhesive; S3, making a pre-filling carbon fiber sheet provided with middle holes, and placing the pre-filling carbon fiber sheet on a tool cone; S4, winding a carbon fiber bundle on the surface of the carbon fiber sheet, and sticking the carbon fiber bundle with the steel bar planted adhesive, so that the carbon fiber filler (the carbon fiber sheet), which is wound, adapts to a to-be-filled space; S5, applying adhesives to the inner wall and fracture surface of the cleaned racket frame, filling the racket frame with the carbon fiber filler which is prepared in the step S4, and perforating the carbon fiber filler in the locations of two sideholes of the fracture after curing and binding; and S6, pulling out the tool cone, and inserting a wire inserting pipe for conducting threading. According to the repairing method provided by the invention, by filling the fracture of the racket frame in a mode of winding the carbon fiber bundles outside the carbon fiber sheets and by perforating the middle holes in the carbon fiber sheet, the repaired badminton racket frame is firm and high in intensity, and repeated fracture, which can occur easily, can be prevented.

Description

technical field [0001] The invention belongs to the technical field of racket repair, in particular to a method for repairing a badminton racket frame. Background technique [0002] At present, due to improper force or long-term use when people play badminton, the racket will hit a hard object and the racket frame will break or cracks will appear. The network cable will also break sometimes, which will affect the use of the racket. The fracture or crack of the racket frame is generally near the weaker threading hole of the racket frame. The existing repair method is usually to directly bond the fracture with adhesive glue, and then re-thread. Although this repair method of direct bonding can be bonded in a short time, due to the existence of cracks, the racket after bonding is likely to break again at the original cracks, which affects the service life of the racket. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention...
