Description

A kind of fixed exercising auxiliary device of large arm

Technical field

The utility model relates to a kind of fixed exercising auxiliary device of large arm, the strength transmitting auxiliary for belonging to table tennis movement is corrected Device.

Background technique

Table tennis is referred to as " national ball game ", and table tennis is the most popular sports items in China.It is well known that table tennis is instructed White silk will be picked up from doll, i.e., just student must be allowed to grasp correctly movement by Standardization Requirement since begining to learn.Especially cultivate Correct strength transmittance process, it is even more important.Past mainly instructs in words and by deeds by coach, makes a demonstration, but still has repeatedly Part student is difficult to grasp specification movement, and the bad habit movement that some students have formed is difficult to correct.In patent document, although Have various table tennis training instruments, but transmits auxiliary fixer for power without special.

Especially in beginner or amateur, often in forehand smash, brandishing for arm wing can be only utilized, Such limited strength, cannot get the ball of high speed, and correct and professional ball-driving method be by foot, leg, waist, back, The multiple links in arm portion are had an effect in conjunction with rotation, the higher ball of quality can be just got in this way, especially between foot, waist and arm Be linked, be the key point having an effect.

Utility model content

The utility model technical issues that need to address be in view of the above shortcomings of the prior art, and it is solid to provide a kind of large arm Determine exercising auxiliary device.

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

A kind of fixed exercising auxiliary device of large arm, including body support interconnected portion and big fupport arm portion, body support portion and big fupport arm Portion is the laminated structure that section is arc, and the angle between body support portion and big fupport arm portion is 25 ° -35 °, and body support portion is attached at people Body rib cage position, big fupport arm portion are attached on rear side of big arm.

Scheme as a further preference is separately provided for package large arm in two side edges in the big fupport arm portion The limit of wing is wrapped up, and the length of the limit package is less than the length in big fupport arm portion.

Scheme as a further preference, the height of the limit package are 11cm to 15cm, and length is 10cm to 15cm.

Scheme as a further preference, width of the big fupport arm portion by middle position are greater than big fupport arm portion by both ends position The width set.

Compared with prior art, the fixed exercising auxiliary device of a kind of large arm of the utility model, big arm can be kept opposite with Trunk is fixed, and is integrated trunk with big arm, is first upper body when being swung the bat with auxiliary exercise in favor of realizing upper foot-propelled Rotary motion, the memory that tones up the muscles make to swing the bat to form foot's drive all-around exercises, avoid only brandishing big arm, be fixed by large arm The constant connection of practice part can achieve the transmitting consciousness that foot's strength sufficiently passes through waist, back and large arm be reached, with just Strength is further transferred to forearm, wrist and finger by true mode of transfer force, and the speed and vigor swung the bat is performed to maximum, Get the quality highest of ball.

Detailed description of the invention

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

Wherein, 1- body support portion, the big fupport arm portion 2-, 3- limit package.

Specific embodiment

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

A kind of fixed exercising auxiliary device of large arm of the utility model, in large arm racked swing, common malfunction is When having an effect, often hand is had an effect has an effect greater than foot, and the strength of foot is difficult transmitting to hand, or is difficult sufficiently to pass It is delivered on hand, when not noticing the problem, no matter trains and how to demonstrate skill of swinging the bat, all indigestions make full use of foot The skill having an effect, the level still more trained is also multifarious, and the fixed practice part of large arm is the relatively fixed power transmitting of large arm Auxiliary apparatus, correctly movement be not large arm and trunk be it is fixed, it is temporarily fixed big simply by the auxiliary apparatus The activity of arm is had an effect wait learning waist using foot after causing the rotation of trunk, then can take away auxiliary apparatus.

As shown in Figure 1, the fixed assistor of large arm includes body support interconnected portion 1 and big fupport arm portion 2, body support portion 1 and big Fupport arm portion 2 is the laminated structure that section is arc, and the angle between body support portion 1 and big fupport arm portion 2 is 25 ° -35 °, body support portion 1 It is attached at human body rib cage position, big fupport arm portion 2 is attached on rear side of big arm, and the practical auxiliary apparatus is exactly us before playing ball The fixed module of upper body nature erect-position, be exactly left foot slightly before, right crus of diaphragm later, bipod separate it is slightly wider shoulder to shoulder, keep containing chest, draw the abdomen, Heavy shoulder, two legs are micro- to bend, and lean forward from the waist, two hands are put in the movement of front naturally, which is exactly in order to which bat is held in fixation Hand is put in front naturally, makes arm and body becomes an entirety naturally and the tool that does, between body support portion 1 and big fupport arm portion 2 Angle be exactly erect-position angle under natural conditions, be placed in large arm naturally in big fupport arm portion 2, this fixed mode Training is lower will gradually to form the consciousness habit for being transferred to waist naturally with human hair combing waste power, and after taking away auxiliary apparatus, large arm is just The hip beats that nature is had an effect can be gradually recovered；

Further, it is separately provided for wrapping up the limit package of big arm in two side edges in the fupport arm portion 2 3, the length of the limit package 3 is less than the length in fupport arm portion 2, it is preferred that the height of limit package 3 is 11cm, and length is 13cm, width of the big fupport arm portion 2 by middle position are greater than the width for leaning on end positions in big fupport arm portion 2, have in body support portion 1 The bandage being fixed on waist, it is improper with position to avoid falling.

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.
