The specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in further details, following examples do not form restriction of the present utility model.
As shown in Figure 1, callisthenics dumbbell of the present utility model, comprises body 1 and the first end cap 2 being connected with body 1 and the second end cap 3.
The first end cap 2 and the second end cap 3 are arranged at respectively the two ends of body 1, its connected mode can have various embodiments, in the present embodiment, body 1 two ends are respectively arranged with external screw thread, the first end cap 2 and the second end cap 3 are respectively arranged with internal thread, the external screw thread at body 1 two ends respectively with the screw-internal thread fit of the first end cap 2 and the second end cap 3.
Other embodiment, on body 1 two ends and the first end cap 2 and the second end cap 3, be respectively arranged with through hole, when body 1 two ends respectively with the first end cap 2 and the second end cap 3 in conjunction with after, with a bearing pin, pass the first end cap 2 and body 1 one end, with another root bearing pin, pass the second end cap 3 and body 1 other end, thus the fixation of playing.
Wherein, body 1 comprises the first round platform 4, the second round platform 5 and to small end, shrinks the cylinder 6 forming respectively by the first round platform 4 and the second round platform 5.The small end of the first round platform 4 is downward, and the small end of the second round platform 5 upwards, extends the cylinder 6 in the middle of just having formed to small end respectively.In fact, the first round platform 4, the second round platform 5 and cylinder 6 are one-body molded.
On the first round platform 4 and the second round platform 5, be evenly equipped with respectively some cambered surface grooves 17, on the first end cap 2 and the second end cap 3, be evenly equipped with respectively V-type groove 18.Wherein, the width of cambered surface groove 17 is along with round platform radius diminishes and diminishes.In the present embodiment, on the first round platform 4 and the second round platform 5, be evenly equipped with respectively 4 cambered surface grooves 17, on the first end cap 2 and the second end cap 3, be evenly equipped with respectively 4 V-type grooves 18.
As shown in Figures 2 and 3, in the first round platform 4, the second round platform 5 and cylinder 6, be formed with the accommodating cavity being interconnected.Accommodating cavity comprises the first cylinder die cavity 12, the first round platform die cavity 13, the second cylinder die cavity 14, the second round platform die cavity 15 and three cylindrical die cavity 16.
The first fixed block 7 is fixedly installed in the first cylinder die cavity 12, adjustable block 9 is installed in the second cylinder die cavity 14, the second fixed block 11 is fixedly installed in three cylindrical die cavity 16, the first spring 8 parts are built in the first round platform die cavity 13, another part is built in the second cylinder die cavity 14, the second spring 10 parts are built in the second round platform die cavity 15, and another part is built in the second cylinder die cavity 14.First spring 8 one end are connected with the first fixed block 7, and the other end is connected with adjustable block 9 one end, and second spring 10 one end are connected with the second fixed block 11, and the other end is connected with adjustable block 9 other ends.
Under inactive state, the first spring 8 and the second spring 10 are all under the state in former length or slightly compression, when sporter swings callisthenics dumbbell, adjustable block 9 is because effect of inertia can have pressure to the first spring 8 or the second spring 10, the first spring 8 or the second spring 10 produce deformation thereupon, one of them spring generation compressive deformation, and there is to extend deformation in another spring, changed the center of gravity of adjustable block 9 in body 1, and then the center of gravity of whole dumbbell shifts.Moment produces tractive force to sporter's upper limbs, and sporter, in order to reach balance, need to increase muscle strength, namely covert increase sporter's exercise intensity.
Above embodiment is only in order to technical scheme of the present invention to be described but not be limited; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
