The tennis is fixedly connected with elastic rope by connecting rod, and the connecting rod is through tennis along leading to that centrage is opened up
Hole.
Further, the end of the connecting rod is provided with the locating part for keeping out tennis slippage.
Further, the locating part is in class " cross " type, and the inner side of such " cross " type locating part is towards correspondence tennis
The grain groove arc laminating of outer surface.
Further, the outer surface of the connecting rod is connected in an interference fit with the inner surface of through hole on tennis.
The chute of slide block is provided with along bevel direction arrangement, is matched with the inclined-plane of the base upper surface.
Further, the spacing preiection that anti-limited slip block slips chute is provided with the end of the slide block inclined surface downside.
The beneficial effects of the utility model are：
This utility model not only takes up an area that space is little, indoor and outdoor can use, be easy to carry, and by slide block in inclined-plane side
Reciprocating motion upwards, realizes the mutual phase transformation between kinetic energy and potential energy, so as to reach the purpose of buffering, shock-absorbing function.

Code name implication in figure：1-tennis；2-elastic rope；3-base；4-slide block；5-connecting rod；6-locating part；
7-grain groove；8-chute；9-spacing preiection.
Specific embodiment
Referring to shown in Fig. 1, Fig. 2, Fig. 3：This utility model is a kind of tennis training machine, including tennis 1 and pouring weight fixation group
Part, the tennis 1 are connected on pouring weight fixation kit by elastic rope 2, and the pouring weight fixation kit mainly by base 3 and is slided
Block 4 is constituted, and the slide block 4 is slidedly assemblied on the inclined-plane of 3 upper surface of base, and the slide block 4 can be back and forth transported along bevel direction
It is dynamic；The elastic rope 2 is connected to along the reciprocating slide block of bevel direction 4, and in the present embodiment, elastic rope 2 is connected to
Along reciprocating 4 front end face of slide block of bevel direction, the front end face（Refer to 4 end face of slide block of corresponding inclined-plane high side one end）On
It is provided with the connecting hole of connection elastic rope 2.
Above-mentioned tennis 1 is fixedly connected with elastic rope 2 by connecting rod 5, and the connecting rod 5 is opened along centrage through tennis 1
If through hole.And the outer surface of the connecting rod 5 is connected in an interference fit with the inner surface of through hole on tennis 1, with
Reach good fixation.After repeated use, the outer surface of connecting rod 5 is matched somebody with somebody with the interference of the inner surface of through hole on tennis 1
Credit union only also can contact the frictional force between face, and with the passage of use time, more or less occurs in varying degrees
Abrasion.So, while interference fit, the locating part 6 for keeping out the slippage of tennis 1 is provided with the end of the connecting rod 5.
In order to prevent from hitting the impact hit to tennis 1 of locating part 6 during tennis 1, locating part 6 is designed to into class " cross " type（This
In class " cross " type locating part 6 be to be designed according to 7 Corresponding matching of grain groove intrinsic on tennis 1.It is of course possible to
Grain groove 7 on other different tennises 1 changes the shape of locating part 6, the correspondence of locating part 6 is embedded in the surface of tennis 1）,
And the inner side of such " cross " type locating part 6 makes whole limit towards 7 arc of the grain groove laminating of correspondence 1 outer surface of tennis
Position part 6 is all disappeared in 1 outer surface grain groove 7 of tennis.Wherein, connection elasticity is provided with the head end of the connecting rod 5
The connecting hole of rope 2.
The chute 8 of slide block 4, the chute are provided with along bevel direction arrangement, are matched with the inclined-plane of 3 upper surface of above-mentioned base
Opposite flanging is provided with 8 left and right sides.Anti- limited slip block 4 is provided with the end of 4 inclined surface downside of the slide block to slide
Try to shirk responsibility the spacing preiection 9 of groove 8, after tennis 1 is gone out by impact, a traction slide block 4 can be produced and transported from inclined-plane downside to high side
It is dynamic, potential energy is converted kinetic energy into, when the spacing preiection 9 and the inclined-plane downside matched on inclined-plane of 4 inclined surface downside end of slide block
When chute 8 is kept out, kinetic energy is converted into potential energy and finishes, and slide block 4 will not continue, to the high lateral movement in inclined-plane, to play pouring weight fixation kit
Good buffering, cushioning effect are arrived；When tennis 1 falls after rise, in the presence of slide block 4 has gravity, along inclined-plane from high side to downside
Motion, by original potential energy again translation bit kinetic energy, until the end of 4 inclined surface downside of slide block to 3 upper surface of base is
Only.
Further, since the conversion between kinetic energy and potential energy, ensures buffering, shock-absorbing function well, meanwhile, reduce tennis
Requirement in training aidss to 3 weight of base.According to actually used situation, corresponding loss of weight process can be carried out to base 3.This reality
Apply in example, the chamfered portion of 3 upper surface of base integrally raises up, the part beyond chamfered portion is sunk, constitute ledge structure,
Reach the purpose for mitigating weight.Also multiple lightening holes are opened up or on the base 3.
Above concrete technical scheme only to illustrate this utility model, rather than a limitation.Although with reference to above-mentioned concrete skill
Art scheme has been described in detail to this utility model, it will be understood by those within the art that：Which still can be right
Above-mentioned concrete technical scheme is modified, or carries out equivalent to which part technical characteristic；And these are changed or replace
Change, do not make the essence of appropriate technical solution depart from spirit and scope of the present utility model.
