Description

A kind of big forearm connection inertia fixator

Technical field

The utility model relates to a kind of big forearms to connect inertia fixator, and the strength transmitting auxiliary for belonging to table tennis movement is entangled Positive device.

Background technique

We in the training process, either professional athlete or amateur, in the transmitting of shot strength In the process, the strength of sole is transmitted to during arm, and more or less that all there is fluencies is inadequate, and inertia action is not strong, Lack and normally waves ball so that affecting the speed of service of ball similar to that inertia action for getting rid of club when playing golf Movement should be the rotation by waist, drive the swing of large arm, combine forearm to arrive relative to big double inside arms under this inertial states The contractive action of inward turning completes racked swing, and in hands-on, common malfunction is large arm during body rotations The autonomous inertia action brandished, and do not become large arm of having an effect, and directly independently had an effect by big forearm, lack waist and drives large arm Inertia, the problem of striking force deficiency is caused, if giving full play to the pendulum model inertia action of big forearm, the ball struck away Speed must be very fast.After inertia action is formed a habit, fixator is laid down, it is small in the case where whipping large arm Arm just has one and naturally shrinks, to reach the natural transmitting of strength, the strength of such foot could be really transferred to Waist, back, large arm, forearm, wrist, finger, such coherent movement of having an effect, just can make ball reach optimal speed.

Utility model content

The utility model technical issues that need to address are in view of the above shortcomings of the prior art, and to provide a kind of big forearm Connect inertia fixator.

In order to solve the above technical problems, the technical solution adopted in the utility model is:

A kind of big forearm connection inertia fixator, including lower supporting portion and upper cover part, the lower supporting portion include interconnected Parcel under parcel and forearm under large arm, the upper cover part includes wrapping up on parcel and forearm in large arm interconnected Portion, parcel under parcel, forearm under the large arm, parcel in large arm, parcel is the item that section is arc on forearm Shape structure has connecting rope between parcel in parcel and large arm under the large arm, under the forearm in parcel and forearm Also there is connecting rope between parcel.

Scheme as a further preference, the angle under the large arm under parcel and forearm between parcel is 90 °- 120 °, the angle in the large arm on parcel and forearm between parcel is 90 ° -120 °.

Scheme as a further preference, the length of parcel is greater than the length of parcel under large arm, institute under the forearm The length for stating parcel on forearm is greater than the length of parcel in large arm.

Scheme as a further preference, the length of parcel is 10cm -12cm, parcel under forearm under the large arm Length be 11cm -14cm, the length of parcel is 9cm -11cm in large arm, and the length of parcel is 10cm-on forearm 13cm。

Compared with prior art, a kind of big forearm of the utility model connects inertia fixator, can be made by fixator Large arm and forearm form an entirety, in square stance of swinging the bat, hinder forearm with respect to the contractive action of large arm, trainer is forced to reverse Waist drives large arm to swing the bat with the rotation of body, will be with body when unloading fixator, then swinging the bat after forming a habit Rotation drive large arm brandish, formed inertia, and forearm be detached from limitation after also can natural shrinking, under inertial states of swinging the bat further Increase striking force, increases striking force and speed.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Wherein, parcel under 1- large arm, parcel under 2- forearm, parcel in 3- large arm, parcel on 4- forearm.

Specific embodiment

The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figure 1, a kind of big forearm of the utility model connects inertia fixator, including lower supporting portion and upper cover part, institute Stating lower supporting portion includes that parcel 2, the upper cover part include interconnected big under parcel 1 and forearm under large arm interconnected Parcel 4 on parcel 3 and forearm on arm, parcel 2 under parcel 1, forearm, parcel 3, forearm in large arm under the large arm Upper parcel 4 is the strip structure that section is arc, the arc section end of parcel 1 and parcel 2 under forearm under large arm The connection of arc section end, common support are wrapped up on the arc section end of parcel 3 and forearm on the lower part of large arm and forearm, large arm The arc section end in portion 4 connects, and covers the top in large arm and forearm jointly, it is relatively large to limit forearm for this fixator in this way The contraction movement of arm makes large arm and forearm form an entirety, when fixator forms the effect of inertia of large arm forearm, is conducive to Increase the strength and speed of batting.

There is connecting rope, parcel 2 and small under the forearm under the large arm in parcel 1 and large arm between parcel 3 Also there is between parcel 4 connecting rope on arm.

Angle under the large arm under parcel 1 and forearm between parcel 2 is 90 ° -120 °, parcel in the large arm 3 and forearm on angle between parcel 4 be 90 ° -120 °, it is relatively easy, naturally, can more know from experience in this angular range To inertia action.

The length of parcel 2 is greater than the length of parcel 1 under large arm under the forearm, the length of parcel 4 on the forearm Degree is greater than the length of parcel 3 in large arm, and specifically, the length of parcel 1 is 10cm -12cm under the large arm, under forearm The length of parcel 2 is 11cm -14cm, and the length of parcel 3 is 9cm -11cm in large arm, the length of parcel 4 on forearm For 10cm -13cm, the needs of most of trainers are generally adapted, dimensions above is referential data, according to actual use person Hand size and change.

Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model The utility model processed, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done, It should be included within the scope of protection of this utility model.
