Description

A kind of offensive racket of improvement

Technical field

The utility model relates to the field of sports speciality, especially a kind of offensive racket of improvement.

Background technology

Racket generally consists of the joint of racket head, dabber, handle and frame and dabber.The length of a racket is no more than 68 centimetres, wherein racket handle and ball rapping bar length are no more than 40 centimetres, and frame length is 28 centimetres, and wide is 23 centimetres, along with scientific and technical development, the future development that the development of racket is more and more lighter towards weight, frame is more and more harder, dabber elasticity is become better and better.

The racket using is at present left following defect: 1, frame head end is all for round end designs, and it has reduced the region of batting; 2, conventional racket, great majority are all the multi-thread designs in a hole, have line and line overlap, thereby affect tension force and the elastic force of line; 3, most frame is hollow structure, and it easily, when bouncing, causes vibrations, affects result of use; 4, the defect of Heavy Weight; The spacing of the graticule of the bat net 5, using is generally all more than 8mm, it exists line-spacing too large, and the tensile strength that makes to clap net relatively a little less than, and its netting twine is that plastic optical fibre material is made, do not possess durability, elastomeric characteristic, thereby affect user's performance.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of offensive racket of improvement, its project organization rationally and can to realize result of use good.

The utility model solves the technical scheme that its technical problem adopts: a kind of offensive racket of improvement, comprise handle, the dabber being connected with handle and the bat net that is connected to the frame on dabber and is connected with frame, on the madial wall of described frame head end, have and extend internally and towards the interior extension edge of outer incline, in it, extension edge makes the head end inner side of frame be flat-head shape, on described frame sidewall, circumferentially offer a plurality of single-pass diatom holes of frame center as fixed point of take, in each single-pass diatom hole, be plugged with the T-shaped line cap of hollow structure, the tapered structure of endoporus of T-shaped line cap, clapping net is located in frame through T-shaped line cap, described frame consists of the pipe fitting of internal cavity structure, in the internal cavity of its pipe fitting, be filled with bumper and absorbing shock material, described frame afterbody is built-in with T connector, the montant end of T connector peaks at the top of dabber.

In order to make frame have higher stability, the material of described T connector is epoxy resin.

In order in use to reduce windage, described dabber is hollow type carbon element nanotube, is outwards vertically extended with brokenly wind sheet on the surface of its dabber.

In order to increase the buffering between palm and handle in use, described handle outer surface is coated with damping collodion.

Described bumper and absorbing shock material is that rubber pange is cotton.

In order to improve the intensity of netting twine and described bat net, by the some warps that are parallel to each other and the some parallels that are parallel to each other, interlock and form, spacing between its adjacent two warps is 5.5mm, spacing between adjacent two parallels is 6.5mm, the spiral wire that is wound with on described warp, the diameter of lateral cross section wiry is 0.2mm.

The beneficial effects of the utility model are: the offensive racket of described a kind of improvement, adopt the racket of this kind of design, and adopt the frame of tack structure, can keep enough precision and speed; In frame, fill bumper and absorbing shock material, can effectively block square stance and impact the harmful vibrations that cause; Adopt carbon element nanotube as dabber, can possess firm structure, can promote dabber performance, the hardness of dabber, flexible toughness are all significantly promoted, better meet the requirement of senior sportsman to high-performance racket simultaneously.
