Detailed description of the invention

Refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of first preferred embodiment of this utility model, being that a kind of middle tube of battledore strengthens structure, in this, pipe 10 has upper end 11 and bottom 12, and this upper end 11 and bottom 12 lay respectively at the opposite end of middle pipe 10.Wherein, upper end 11 is for union joint frame 20, and bottom 12 is used for connecting handle 30.

As in figure 2 it is shown, described middle pipe 10 is to adopt carbon fiber, glass fibre or Ke Weila fibrous material to make, in this, the profile of pipe 10 is pipe, and center is hollow structure, and a through hole 13 is through to bottom 12 by the upper end 11 of middle pipe 10.In the present embodiment, this upper end 11 is provided with enhancing structure 14 to internal the thickening of through hole 13, and this enhancing structure 14 is circular casing, and it is formed in one with middle pipe 10 and is connected.After molding, in this, the internal diameter of pipe 10 upper end 11 is more than the internal diameter of middle pipe 10 other parts, and the external diameter entirety of middle pipe 10 is unchanged.

As shown in Figure 3, a lot of owing to strengthening the tube wall thickening making middle pipe 10 after structure 14 is arranged, the tube wall at other position is relatively thin, right angle offset 15 is formed between the internal face of the through hole 13 at position and other position corresponding to structure 14 thus strengthening, after impacting racket energetically, may be susceptible to rupture in right angle offset 15 position, therefore, the present embodiment devises ramp type transition structure 16, the strength that impact produces is made to conduct the other parts to middle pipe 10 equably from enhancing structure 14 smoothly, thus the overall uniform force of middle pipe 10, it is not easy to fracture.
