Embodiment one
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.A kind of dismountable tennis is hit exerciser, and its structure includes：One convex balancing weight
2 and a recessed balancing weight 3.
The convex balancing weight 2 includes a projection body 21, a nub side shell 22 and a umbo component 23.The projection body 21
Side be provided with the nub side shell 22, the outside of the nub side shell 22 is provided with a umbo component 23.
The recessed balancing weight 3 includes a concave block body 31, a concave block side shell 32 and a recessed joint portion 33.The concave block body 31
Side be provided with concave block side shell 32, the outside of concave block side shell 32 is provided with a recessed joint portion 33.The recessed combination
Portion 33 can be combined with the umbo component 23 so that recessed balancing weight 3 is fixed with the assembling of convex balancing weight 2.The recessed joint portion 33 with
The umbo component 23 assembles fixation in a manner of screw lock.The umbo component 23 is a bar structure and is provided with outside convex
Screw thread 231, the recessed joint portion 33 is a shrinkage pool structure and inner side is provided with recessed screw thread 331.
Reference picture 1, Fig. 2, Fig. 3 and Fig. 4.When needing to be trained, exerciser can be attached on tennis racket 4 by user,
Convex balancing weight 2 is placed on tennis racket 4 first and claps the one side of net 42, and make umbo component 23 pass through netting twine 43 between space after, then
Recessed balancing weight 3 is placed on to the another side for clapping net 42, and makes the corresponding umbo component 23 in recessed joint portion 33, is finally rotated further by concave block body 31
Recessed screw thread 331 and convex thread 231 are screwed togather and locks and netting twine 43 is sandwiched between nub side shell 22 and concave block side shell 32,
The convex balancing weight 2 and the assembling of recessed balancing weight 3 are fixed on the netting twine 43 of tennis racket 4 by can, and user grips tennis racket 4
Bat 41 to practise swinging the bat when, because of the additional weight of exerciser of tennis racket 4, so user must expend more when swinging the bat
Big strength, so as to reach the effect for tempering arm muscles, and user waves in the case where tennis racket 4 has added weight
Clap, naturally upward correct posture of swinging the bat when can also keep over.
Embodiment two
Reference picture 5, Fig. 6 and Fig. 7.The embodiment of the present embodiment is substantially the same with embodiment one, and its difference is,
The convex balancing weight 2 assembles fixation with recessed balancing weight 3 by the way of magnetic, and the umbo component 23 divides with recessed joint portion 33
Not Wei projection and shrinkage pool structure, and be provided with a projection magnetic part 211 in the projection body 21, the projection magnetic part 211 leans on
Nearly nub side shell 22, a concave block magnetic part 311 is then provided with concave block body 31, the concave block magnetic part 311 is described close to concave block side shell 32
Projection magnetic part 211 is correspondingly arranged on nub side shell 22 and concave block side shell 32 with different magnetic poles respectively from concave block magnetic part 311, described
Projection magnetic part 211 extremely corresponds to the nub side shell 22 with N, and the concave block magnetic part 311 then extremely corresponds to concave block side shell with S
32。
When exerciser is arranged on tennis racket 4, convex balancing weight 2 is placed on to the one side for clapping net 42 first, and make convex
Engaging member 23 pass through netting twine 43 between space after, then by recessed balancing weight 3 be placed on clap net 42 another side, and make recessed joint portion 33 with
After umbo component 23 is mutually correspondingly fitted together to, the projection magnetic part 211 and concave block magnetic part 311 also mutual magnetic, pressed from both sides netting twine 43
After putting between nub side shell 22 and concave block side shell 32, convex balancing weight 2 and the assembling of recessed balancing weight 3 are fixed on to the net of tennis racket 4
On line 43, when user grip the bat of tennis racket 4 41 to swing the bat when, the magnetic of the projection magnetic part 211 and concave block magnetic part 311
Power can make convex balancing weight 2 be maintained at the state of combination without separating with recessed balancing weight 3.
Concave block side shell 32 is made by the material of compressible deformation, such as rubber or silica gel, and the umbo component
23 are equally set to the structure of projection and shrinkage pool with recessed joint portion 33, and umbo component 23 is mutually corresponding chimeric with recessed joint portion 33
Afterwards, because the recessed joint portion 33 is recessed as the concave block side shell 32 made by compressible deformation material, so umbo component 23
The side wall of recessed joint portion 33 can be extruded and it is produced deformation, so that the side wall of recessed joint portion 33 can produce to umbo component 23
Compel the effect fastened, prevent umbo component 23 from departing from from recessed joint portion 33.
Embodiment three
Reference picture 8.The embodiment of the present embodiment is substantially the same with embodiment one, and its difference is, described convex to match somebody with somebody
Pouring weight 2 assembles fixation with recessed balancing weight 3 by the way of cemented, and being set between the umbo component 23 and recessed joint portion 33 can
The devil's felt component mutually sticked, and be also respectively equipped with the projection body 21 with concave block body 31 projection magnetic part 211 with it is recessed
Block magnetic part 311, thus by exerciser be arranged on tennis racket 4 on when, just can be by the umbo component 23 of convex balancing weight 2 and recessed counterweight
The recessed joint portion 33 of block 3 pass through the space between netting twine 43 and mutually it is corresponding stick after, can be by convex balancing weight 2 and recessed balancing weight 3
Assembling is fixed on tennis racket 4, and the magnetic attraction between the projection magnetic part 211 and concave block magnetic part 311 can make convex balancing weight 2
Fix more firm with the assembling of recessed balancing weight 3.
The overall structure of this creation is simple, rapidly can install or dismantle in tennis racket because described in, and is being provided with
Good convenience, and simple structure can also be effectively reduced manufacturing cost, and this creation also is provided with good practical valency
Value.
The utility model is simple in construction, ingenious in design, the advantage is that, by setting a pair of convex-concave counterweights with engaging member
Block, after engaging member to be passed through to user space and combination between racket netting twine, convex balancing weight and the assembling of recessed balancing weight can be fixed
At the netting twine position of tennis racket, the weight of racket can be increased after exerciser is installed, allow user when practising racked swing, both
The posture of swinging the bat of oneself can be corrected, can also train the muscles of the arm, installation and removal are also easier to be quick, and train on is more
It is good.
Exerciser of being hit above to a kind of dismountable tennis provided by the utility model is described in detail.Herein
