The specific embodiment
Below in conjunction with accompanying drawing trainer of the present utility model is described in detail.
As shown in Figure 1, trainer of the present utility model includes a bedplate 1 and is installed in folded turnover extension board 2 on the bedplate 1, that be used for installing elastic holder 3; Also include the bearing bracket stand 4 for carrying spheroid 12, described bearing bracket stand 4 is installed on the elastic holder 3 by holding screw 6.Wherein, bedplate 1 is in order to carrying and fixing trainer of the present utility model, so bedplate 1 will have certain weight, in order to avoid in the time of breaktest, leave both allocations.The bottom of bedplate 1 can be with anti-skidding stop washer, guarantees further to prevent that slippage from offing normal.And folded turnover extension board 2, include two extension boards 22 (Fig. 2) that connected by hinge means 21, such structure just can make extension board 22 overturn and to fold, thereby makes spheroid 12 can be in different positions, satisfies the needs of different technologies exercise.One of them extension board 22 front end is equipped with plug 23, and plug 23 can be made with the metal iron plate, has certain extensibility and elasticity, is used for cooperating the height of extension board 22 or angle to change.
In order to make things convenient for the dismounting of the utility model trainer, be convenient for carrying and transport, the utility model is fixed with an adapter 7 at bedplate 1, and this adapter 7 also is to make with metal, and hook 8 is housed on it, is used for tangling elastic force drag-line 9 (Fig. 3).When in use, the plug 23 of extension board 22 front ends is inserted in the adapter 7, because the middle part of plug 23 has two breach, plug 23 is stuck in the adapter 7, thereby allow the folded turnover extension board 2 can free perk, in order to carry out Height Adjustment.
On another extension board 22 of folded turnover extension board 2, by holding screw 6 elastic holder 3 is installed, elastic holder 3 has certain elasticity, when carrying out breaktest, the lodging of can taking advantage of a situation rapidly, and so that trainer has buffering and playback ability when impacting, so that the process that the real simulation table tennis impacts continuously.Simultaneously, holding screw 6 can carry out elastic holder 3 adjustment of continuous rotation angle easy and conveniently and fix the requirement of different angles (Fig. 4) when being convenient to breaktest.And by another holding screw 6, at elastic holder 3 bearing bracket stand 4 is installed, on two legs 41 of bearing bracket stand 4 with a pair of axis hole 42, the steel axle 51 of special spheroid 5 can be run through wherein, make spheroid 5 smooth rotation thereon, so that the real simulation table tennis is impacting the rotate effect of taking advantage of a situation (Fig. 5) of process.And, owing to can the tightness of holding screw 6 be regulated, can free-handly bearing bracket stand 4 be carried out the adjustment of continuous rotation angle and fixing easy and conveniently.The requirement of the different angles when being convenient to breaktest.
The stability of trainer in order to guarantee to impact, on training period also with elastic force drag-line 9 and damping stop drag-line 11.Its elastic force drag-line 9 and damping stop drag-line 11 can be the materials that resilient rubber bar or other can play flexible tensioning function.One of elastic force drag-line 9 hangs on the hook 8, and the other end hangs on the elastic holder 3, when folded turnover extension board 2 is in folded state, folded turnover extension board 2 is produced a stable pulling force that tightens up, and stops opening of folded turnover extension board 2.Simultaneously, also can to elastic holder 3 produce one backward, downward stable pulling force, to guarantee to have preferably elasticity and playback ability.
And an end of damping stop drag-line 11 hangs on the damping stop drag-line hook 10, and the other end also hangs on the elastic holder 3, gives the position for elastic holder resilience 3 and limits, and prevents this device pendulum that quivers back and forth.Like this, under the acting in conjunction of elastic force drag-line 9 and damping stop drag-line 11, trainer of the present utility model can effectively reduce the vibration that batting causes, and guarantees the validity (Fig. 6) of training.
In addition, spheroid 5 of the present utility model utilizes real table tennis, makes it have the sense of reality of simulation.And by special processing, make it have a built-in steel axle 51, and attach retaining wall material 52 at spheroid outer wall steel axle 51 places, have stronger anti-strike ability to guarantee it.Retaining wall material 52 can be the material of table tennis homogeneity, for example celluloid or rigid plastics, and spheroid 5 splits at steel axle 51 places when preventing from impacting.
Because the utility model has carried out particular design to folded turnover extension board 2, make extension board 22 can open as required or fold, can also be by the Height Adjustment to folded turnover extension board 2.On Height Adjustment, can adopt simple or complicated equipment dealing to finish, the utility model adopts height adjustment pad 12 to finish, and the number of height adjustment pad 12 is no less than 1, is made by flexible material, impacts for training, produces certain cushioning effect.And because the size of its length can be adjusted arbitrarily, therefore, different combinations can produce different Height Adjustment effects.
Training cartridge of the present utility model is equipped with two kinds of basic use patterns, respectively the training of corresponding top spin and the training of chop.Two kinds of patterns can arbitrarily be changed as required.
Pattern one: the training of top spin, this moment, the folded turnover extension board 2 of trainer was in folded state:
With on the table top appropriate locations such as trainer placing flat billiard table or dining table, desk (such as Fig. 1), to swing the bat facing to spheroid 5 half bumps on the bearing bracket stand 4, half friction repeatedly impacts and gets final product.Along with impacting, the spheroid 5 on the bearing bracket stand 4 can be taken advantage of a situation and be lodged forward rapidly, and can rotate rapidly and uniformly.If the music beat accompaniment is arranged, effect is better.The person that begins to learn the table tennis preferably has the coach to give corresponding guidance to shot.This trainer can carry out the positive and negative hand attacking driving of table tennis, toe lift, lifting the ball, turns the simulated training of ball basic training on the stubborn ball etc.In the exercise, also can simulate the variation of carrying out course of action and attack.Such as straight line, oblique line, Zhong Lu, to a high-profile, preshoot etc. carries out simulated training.Also two different trainers of height can be put into respectively the relevant position, stride about carrying out, the paces training such as leapfrog, cross steps.There is not training mate but to surpass training mate.In short time, can receive good training effect, particularly the feel of friction ball be set up, forming of elemental motion has good training effect.
The training of pattern two, chop:
At this moment, elastic force drag-line 9 is taken off, 2 upsets of folded turnover extension board are opened, the spheroid 5 on the spheroid bearing bracket stand 4 is by becoming down (Fig. 8) up.Trainer after the upset is placed into the table top appropriate location, spheroid 5 is leant out the table top outer, height adjustment pad 12 is filled between bedplate 1 and the extension board 2 carried out Height Adjustment, the training that namely can chop afterwards.
