Abstract

The utility model discloses an improved middle tube of a battledore, which comprises a hollow main body, wherein the hollow main body is made of carbon fiber material, and the inner diameter of the hollow main body close to the tube body of a battledore frame is gradually reduced in the direction of the battledore frame. Through the gradual reduction of the inner diameter of the hollow main body close to the tube body of the battledore frame in the direction of the battledore frame, the center of gravity of the hollow main body approaches toward the battledore frame or a handle, an elastic force-bearing point corresponding to the hollow main body approaches toward the handle or the battledore frame, so as to effectively enhance the elasticity of the hollow main body, increase the elastic force in batting to obtain the optimal batting effect, and be helpful for the full play of the skills of a player.

Description

Manage in the modified racket

Technical field

The utility model relates to the racket art, refers in particular in a kind of modified racket to manage.

Background technology

Racket is along with the prosperity of science and technology, and making body develops into carbon fibre composite from metal tube in the past and makes, and makes the more light and handy portable of racket, and badminton is also general always to be liked.Yet, be incisively and vividly with the badminton skill performance, except playing skill was superior, the function of racket performance itself can not be ignored more.

Prior art mesoptile racket is made up of the frame that is installed with line, middle pipe, three major parts of handle.The middle good racket of tubular elastic is subjected to liking of player, but since existing racket in the pipe its wall thickness by front end all the rear end be uniform substantially, square stance elastic force balance point is arranged in the middle part of racket pipe, make the player feel the elasticity deficiency at square stance, can not obtain best balling effect, thereby also make player's level performance be restricted.

The utility model content

In view of this, the utility model is at the disappearance of prior art existence, and its main purpose provides in a kind of modified racket and manages, and it can effectively solve the problem of tubular elastic deficiency in the existing racket.

For achieving the above object, the utility model adopts following technical scheme:

Manage in a kind of modified racket, include hollow body, this hollow body is a carbon fibre material, and this hollow body reduces along the frame direction gradually near the internal diameter of the body of frame.

As a kind of preferred version, described hollow body includes the first half body and the latter half body of one-body molded connection; This first half body is near frame, and the internal diameter of this first half body reduces gradually along the frame direction; This latter half body is near handle, and the internal diameter of this latter half body is even.

As a kind of preferred version, the external diameter of described latter half body is even, and the external diameter of this first half body reduces gradually along the frame direction.

As a kind of preferred version, the pipe thickness of described first half body is even.

As a kind of preferred version, the pipe thickness of described first half body is along frame direction attenuate gradually.

As a kind of preferred version, the external diameter of described first half body is even, and the external diameter of first half body is identical with the external diameter of latter half body.

As a kind of preferred version, the length of described hollow body is 295mm, and the length of this latter half body is 80mm.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, as shown from the above technical solution: reduce gradually along the frame direction near the internal diameter of the body of frame by utilizing hollow body, make that the center of gravity of hollow body is close to frame or handle, close to elastic force balance point that should hollow body to handle or frame, effectively strengthen the elasticity of hollow body, the elasticity dynamics that improves square stance to be obtaining best balling effect, thereby helps to make player's playing skill to be not fully exerted.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

The accompanying drawing identifier declaration:

10, hollow body 11, first half body

12, latter half body 20, frame

The specific embodiment:

Please refer to shown in Figure 1A to Fig. 2 B, the concrete structure that it has demonstrated first preferred embodiment of the utility model includes hollow body 10, and this hollow body 10 is a carbon fibre material, and carbon fibre material has the advantage that density is low, tensile strength is high.This hollow body 10 includes the first half body 11 and the latter half body 12 of one-body molded connection.This first half body 11 is near frame 20, and the internal diameter of this first half body 11 reduces gradually along frame 20 directions.This latter half body 12 is near the handle (not shown), and the interior external diameter of this latter half body 12 is even, and promptly pipe thickness is also even.

Shown in Fig. 1 and Fig. 2 B, the external diameter of end face is identical with the external diameter of latter half body 12 after the first half body 11, and the external diameter of this first half body 11 reduces gradually along frame 20 directions, the internal diameter of this first half body 11 also reduces gradually along frame 20 directions, and the pipe thickness of this first half body 11 is evenly or along frame 20 directions attenuate gradually.The pipe thickness of the first half body 11 in the present embodiment is attenuate gradually, and shown in Fig. 1 to Figure 1B, the total length of this hollow body 10 is 295mm, wherein, the length of this latter half body 12 is 80mm, and the external diameter of this latter half body 12 is 7.5mm, and internal diameter is 4.7mm; The external diameter of end face is 6.5mm before this first half body 11, and internal diameter is 4.3mm.Shown in Fig. 2 to Fig. 2 B, be the another kind of size type of present embodiment, its structure with Figure 1A to Figure 1B is identical, different is, the external diameter of this latter half body 12 is 7mm, and internal diameter is 4.2mm, the external diameter of end face is 6mm before this first half body 11, and internal diameter is 3.8mm.
