Description
Technical field
The utility model relates to sports apparatus, especially relates to a kind of adjustable in length, regulates the tennis racket of rear even intensity.
Background technology
In tennis square stance due to ball speed quickly, and the weight ratio of tennis itself is larger, can produce enormous impact strength instantaneously to tennis racket, long-term lasting use carries out with the inharmonic racket of Human Height the easy athletic injury produced organs such as elbows that moves.Therefore, the people of different height preferably uses the tennis racket matched with its height.Current tennis racket is on the market limited length, so always has some can not select the tennis racket adapted with oneself height.
Summary of the invention
For solving the problem, the purpose of this utility model is the tennis racket of the adjustable length providing a kind of adjustable in length, the rear even intensity of adjustment.
The utility model is realized by following technical measures, a kind of tennis racket of adjustable length, comprises frame and handle, and described handle comprises the motion bar of the sheathed fixed bar of fixed bar and top being fixedly connected with frame, and described motion bar can slide axially along fixed bar.
As a kind of preferred embodiment, the cross section of the body of rod above described fixed bar and motion bar is spaced fan-shaped and jointly around being an annular, each fan-shaped a junction that stretches out of described motion bar is also jointly connected to outside motion bar and puts, the each fan-shaped periphery of described fixed bar is connected by a fixed bar overcoat, puts the bar-shaped trough being provided with and supplying the connecting portion of motion bar to slide up and down outside described fixed bar.
As a kind of preferred embodiment, be set to hollow and wherein spiral is provided with an inner screw below described motion bar, upper end and the fixed bar lower end of described inner screw offset.
As a kind of preferred embodiment, the lower end of described inner screw is provided with a cross-shaped rotary bar.
As a kind of preferred embodiment, described motion bar overcoat is flexible boot.
Handle is set to fixed bar and is set in the motion bar on fixed bar by the utility model, wherein motion bar can slide axially along fixed bar, thus before use can according to the total length of the height regulating handle of players, make it harmonious with Human Height in use, avoid inappropriate racket and carrying out the athletic injury that the organs such as elbow are produced that moves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation after the utility model embodiment adjusts length;
Fig. 3 is the structural representation of the utility model embodiment handle portion;
Fig. 4 is the sectional view of the utility model embodiment handle.
Detailed description of the invention
Contrast accompanying drawing below in conjunction with embodiment the utility model is described in further detail.
A kind of tennis racket of adjustable length, please refer to Fig. 1 to Fig. 4, comprise frame 100 and handle 200, described handle 200 comprises the motion bar 202 of the sheathed fixed bar 201 of fixed bar 201 and top being fixedly connected with frame 100, and described motion bar 202 can slide axially along fixed bar 201.
The motion bar 202 that handle 200 is set to fixed bar 201 and is set on fixed bar 201 by this tennis racket, wherein motion bar 202 can slide axially along fixed bar 201, thus before use can according to the total length of the height regulating handle 200 of players, make it harmonious with Human Height in use, avoid inappropriate racket and carrying out the athletic injury that the organs such as elbow are produced that moves.
The tennis racket of the adjustable length of the present embodiment, please refer to Fig. 3 and Fig. 4, the basis of previous technique scheme can also be specifically, the cross section of the body of rod above fixed bar 201 and motion bar 202 is spaced fan-shaped 206,209 and common around being an annular, each fan-shaped 209 of described motion bar 202 stretches out a junction 208 be jointly connected on motion bar overcoat 207, each fan-shaped 206 peripheries of described fixed bar 201 are connected by a fixed bar overcoat 205, described fixed bar overcoat 205 are provided with the bar-shaped trough supplying the connecting portion 208 of motion bar to slide up and down.This structure makes motion bar 202 and fixed bar 201 have close intensity, avoids the breakage phenomenon that varying strength causes.
The tennis racket of the adjustable length of the present embodiment, please refer to figure, the basis of previous technique scheme can also be specifically be set to hollow below motion bar 202 and wherein spiral is provided with an inner screw 203, upper end and fixed bar 201 lower end of described inner screw 203 offset.Thus regulate length by rotating inner screw 203.
The tennis racket of the adjustable length of the present embodiment, please refer to Fig. 3, and the basis of previous technique scheme can also be specifically, and the lower end of inner screw 203 is provided with a cross-shaped rotary bar 204.Convenient rotation inner screw 203.
The tennis racket of the adjustable length of the present embodiment, the basis of previous technique scheme can also be specifically, and motion bar overcoat 207 is flexible boot.
More than that the tennis racket of the utility model adjustable length is set forth; the utility model is understood for helping; but embodiment of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included in protection domain of the present utility model.
