Abstract

The utility model relates to the technical field of sports equipment, in particular to a badminton racket with extended stem. The port of the front hole of the badminton racket wooden handle is designed with a cavity by the badminton racket with extended stem, and the cavity is connected with the front hole; the diameter of the cavity is larger than the diameter of the front hole. The badminton racket with extended stem has the advantages of utilizing the flying height between the cavity and the stem, achieving effective driving ball length of the extended stem without changing the whole length of the badminton racket, increasing driving ball rebound force, having simple structure, and having strong practicability.

Description

The plumage of middle pipe lengthening structure is clapped

Technical field:

The utility model relates to technical field of sports apparatus, refers in particular to a kind of plumage of middle pipe lengthening structure and claps.

Background technology:

It is very popular always as a kind of not only fashion but also the motion that can improve the health to play badminton, when playing badminton, wherein being connected in plumage claps the effective length of hit of middle pipe between wooden handle and the frame framework and can determine the effect of batting, the effective length of hit of middle pipe is long more, and the bounce of its batting is also just big more.Yet, shown in accompanying drawing 1,2, during the plumage of commonly using is clapped, effective length of hit of pipe 61 is confined to the revealed section of middle pipe 61 in the plumage bat, as its length that will extend, and the length that pipe 61 embedding plumages are clapped wooden handles 62 in the entire length of pipe 61 or the minimizing in then needing to increase, and no matter adopt any in this dual mode, it finally all can increase the overall dimensions that plumage is clapped, and increases volume, is unfavorable for carrying and using.

Summary of the invention:

The purpose of this utility model is to overcome the defective of prior art, and the plumage bat of the middle pipe lengthening structure of the effective length of hit of pipe in a kind of can the growth under the condition that does not change plumage bat entire length is provided.

For achieving the above object, the port design in the utility model hole before plumage is clapped wooden handle has a cavity, the preceding in succession hole of cavity, and the diameter of cavity is greater than the diameter in preceding hole.

Described plumage is clapped the also sheathed protheca of wooden handle front end, leaves the gap between the pipe during the part of pipe and plumage were clapped during the outer extension coating plumage of this protheca upper end was clapped; Also make up the soft body of a hollow on the protheca, soft body inner termination is embedded in the cavity.

After adopting such structure, utilize the flying height between cavity and the middle pipe, can reach the effective length of hit of pipe in the growth thereby need not change plumage bat entire length, increase the bounce of batting, it is simple in structure, and is practical.

Description of drawings:

Accompanying drawing 1 is that the plumage of prior art is clapped structural representation;

The wooden handle structural representation that accompanying drawing 2 is clapped for existing plumage;

Accompanying drawing 3 is an overall structure schematic diagram of the present utility model;

Accompanying drawing 4 is that plumage of the present utility model is clapped the wooden handle structural representation.

The specific embodiment:

See shown in the accompanying drawing 3,4, the utility model includes plumage and claps wooden handle 10, frame framework 20 and be connected in plumage and clap plumage between wooden handle 10 and the frame framework 20 and manage 30 in clapping, wherein the front end of plumage bat wooden handle 10 has a preceding hole 11 to make up for pipe 30 embeddings in the plumage bat, the design of the port in hole 11 has a cavity 12 before plumage is clapped wooden handle 10, the preceding in succession hole 11 of cavity 12, and the diameter of cavity 12 is greater than the diameter in preceding hole 11, cavity 12 tapered shapes.Front end and rear end that plumage is clapped wooden handle 10 also are arranged with protheca 13 and back cover 14, wherein also make up the soft body 15 of a hollow on the protheca 13, and soft body 15 inner termination are embedded in the cavity 12.Soft body 15 can be designed to match with cavity 12 and the body of various shapes, to strengthen the aesthetics that plumage is clapped.Leave gap 131 between the pipe 30 during the part of pipe 30 and plumage were clapped during the outer extension coating plumage of protheca 13 upper ends was clapped.

During combination, an end of pipe 30 inserted plumage and claps before the wooden handle 10 in the hole 11 during plumage was clapped, and the diameter of cavity 12 is greater than the diameter in preceding hole 11, not only being convenient to manage 30 in the plumage bat plugs, but also can utilize the flying height between the pipe 30 in cavity 12 and the plumage bat, thereby need not change plumage bat entire length and can reach pipe 30 effective length of hit in the bat of growth plumage, be to manage 30 during the plumage of relative equal length is clapped, the utility model reveals on the basis of segment length in original plumage is clapped outside the pipe 30, design by cavity 12, increased dexterously plumage clap in pipe 30 effective length of hit (it is that the revealed section length of middle pipe 30 adds vacant section and the coating section of protheca 13 outer rims in the upper plenum 12 that the plumage of the utility model is managed effective length of hit of 30 in clapping), increase the bounce of batting, even use lighter dynamics, it is farther also ball to be flown out, it is simple in structure, and is practical.

The embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all do variation or modification according to the described shape of the utility model claim, structure, feature and spiritual principle all should be included in the utility model claim.
