Description
Technical field
A kind of sports goods is the utility model is related to, more particularly to a kind of racket handle and plumage that can reduce stress concentration
Ball top is clapped.
Background technology
General racket is made up of frame, middle pipe, protheca, handle and other accessories.Have on current market very big
The consumer group has light-weighted demand to racket, so to carry out light-weight design to racket handle.
At present, the handle of racket is by wooden or two kinds of carbon fibre material.Wherein, the characteristics of wood handle it is damping effect
Fruit is good, but particularly less than 18 grams light of wooden handle intensity is not high, and wooden handle easily snaps off during consumer's use；Carbon is fine
Dimension is the fabulous material of a kind of specific modulus, specific strength, and the handle that carbon fibre material makes, intensity is good, in light weight, but because of hardness
It is harder, there is the hidden danger for causing stress concentration and causing middle pipe to be broken.
Utility model content
The purpose of this utility model is to provide a kind of racket handle and racket that can reduce stress concentration, to carry
Rise its durable performance.
To achieve the above object, the racket handle that can reduce stress concentration and racket of the present utility model is specific
Technical scheme is：
A kind of racket handle that can reduce stress concentration, is made up of carbon fibre material, wherein, including integrally formed hold
Portion and connecting portion are held, is located on connecting portion formed with chamber resettling, the opening of chamber resettling on the end face of connecting portion, chamber resettling
Opening be provided with the stress collar, the stress collar is made up of soft elastic material, and racket middle pipe is inserted into the appearance on connecting portion
After putting chamber, the stress collar is located between the side wall and racket middle pipe of chamber resettling's opening, to reduce answering in racket middle pipe
Power is concentrated.
Further, the stress collar includes accommodating sleeve and retaining edge edge, and retaining edge is along from the top of accommodating sleeve to extension
Setting is stretched, accommodating sleeve is embedded the inside of the chamber resettling on connecting portion, and retaining edge edge is kept out on the end face of connecting portion.
Further, the opening of the chamber resettling on connecting portion is formed with connecting groove, the accommodating sleeve on the stress collar
It is embedded in connecting groove, the internal face of chamber resettling is concordant with the internal face of accommodating sleeve.
Further, more undertaking projections are arranged at intervals with the internal face of the stress collar, accept projection along the stress collar
Length direction is extended, can be with holding on stress collar internal face after racket middle pipe is inserted into the chamber resettling on connecting portion
Connect projection to be in contact, to disperse the torsion in racket middle pipe.
Further, the outside cladding of the stress collar is provided with hard protective layer, and the hardness of hard protective layer is more than stress set
The hardness of ring, the hardness less than racket handle.
A kind of racket, wherein, including any of the above-described racket handle that can reduce stress concentration.
The racket handle that stress concentration can be reduced and racket of the present utility model have advantages below：Racket is being hit
Caused middle pipe deformation can pass through the buffering of soft elastic material during ball, make the stress of carbon fiber handle reduce, middle pipe
Shearing force reduce, so as to lift the durable performance of racket.
Brief description of the drawings
Fig. 1 is the structural representation of the racket handle of the present utility model that can reduce stress concentration；
Fig. 2 is the profile of the racket handle of the present utility model that can reduce stress concentration；
Fig. 3 is the structural representation of the stress collar in the utility model.
Embodiment
In order to be better understood by the purpose of this utility model, structure and function, below in conjunction with the accompanying drawings, to of the present utility model
A kind of racket handle that can reduce stress concentration and racket do further detailed description.
The racket handle of the present utility model that stress concentration can be reduced is made up of carbon fibre material, as shown in figure 1, this reality
To apply in example, racket handle 1 includes integrally formed grip part and connecting portion, wherein, grip part is held for user, connecting portion
For being connected with racket middle pipe.
Further, as shown in Fig. 2 being located on the connecting portion of racket handle 1 formed with chamber resettling, the opening of chamber resettling
On the end face of connecting portion, the opening of chamber resettling is provided with the stress collar 2, and racket middle pipe 3 can be by positioned at the end of connecting portion
Opening on face is inserted into chamber resettling, to be connected with racket handle 1.
Further, the stress collar 2 is made up of soft elastic material, such as ABS plastic can be used to project and be made, racket
After middle pipe 3 is inserted into the chamber resettling on connecting portion, the stress collar 2 is located at the side wall and racket middle pipe 3 of chamber resettling's opening
Between.Accordingly, because the middle pipe deformation caused by batting can make the stress of handle reduce through the buffering of the overstress collar, middle pipe
Shearing force reduce, so as to lift the durable performance of racket.
Further, as shown in figure 3, the stress collar 2 includes accommodating sleeve 22 and retaining edge along 21, wherein, house sleeve 22
Identical with the shape of the chamber resettling on connecting portion, retaining edge stretches out settings along 21 from the tops of accommodating sleeves 22, accommodating
Sleeve 22 is embedded the inside of the chamber resettling on connecting portion, and retaining edge is kept out on the end face of connecting portion along 21.Specifically,
As shown in Fig. 2 the opening of the chamber resettling on connecting portion, formed with connecting groove, the accommodating sleeve on the stress collar is embedded
In connecting groove, the internal face of chamber resettling is concordant with the internal face of accommodating sleeve.
Further, as shown in figure 3, being arranged at intervals with more undertaking projections 23 on the internal face of the stress collar 2, wherein, hold
Length direction of the projection 23 along the stress collar 2 is connect to be extended, can after racket middle pipe 3 is inserted into the chamber resettling on connecting portion
It is in contact with the undertaking projection 23 on the internal face of the stress collar 2.Thus, caused torsion can be held by more in square stance middle pipe
Connect projection to spread out, avoid because middle pipe is damaged caused by torsion is excessively or too concentrated.
Further, the outside of the stress collar 2 can also coat and be provided with hard protective layer, wherein, the hardness of hard protective layer
The preferably greater than hardness of the stress collar, but less than the hardness of racket handle.For example, the bright face hard plating in existing racket can be used
Layer, that is, the service life of the stress collar is enhanced, in turn ensure that the overall aesthetic of racket.
The racket handle that stress concentration can be reduced and racket of the present utility model utilize the slow of soft elastic material
Punching acts on, and reduces the stress concentration of racket middle pipe, improves the durable performance of racket.
The utility model is further described by specific embodiment above, it should be understood that, have here
The description of body, should not be construed as the restriction to spirit and scope of the present utility model, and one of ordinary skilled in the art is readding
The various modifications made after reader specification to above-described embodiment, belong to the scope that the utility model is protected.
