Description
Technical field
The utility model design field of exercise equipment, is specifically related to a kind of single direction rotation dumbbell of tempering wrist and the quick strength of forearm.
Background technology
As everyone knows, in the training of sport and body-building and athletics sports, dumbbell often can be utilized to strengthen wrist, the strength of arm, traditional dumbbell is primarily of dumbbell plate and bar composition, there is space can relative sliding and rotation between balancing weight and bar, carrying out some position (such as: wrist refers to the quick strengthening exercise bent) and some special item (such as: the forearm in throwing event training and wrist whip exercise fast), use traditional dumbbells dumbbell bar will be driven to rotate because of the rotatory inertia of dumbbell plate, thus the return speed of wrist and arm that slowed down, so reduce the quality of specific exercises and the efficiency of training to a great extent, simultaneously in exercise process, the return action of wrist and arm also will overcome and forms resistance by the rotatory inertia of balancing weight and dumbbell bar, thus cause the serious sense of discomfort of palm inside skin, particularly weight strengthens, speed easily causes injured especially when accelerating.
Utility model content
The purpose of this utility model is to provide one, can in sport and body-building and athletics sports in the training of wrist and the quick strength of arm, accelerate practice frequency and reduce the dumbbell of chance of injury.
Solve the problems of the technologies described above the technical scheme of employing: a kind of single direction rotation dumbbell of tempering wrist and the quick strength of forearm, comprise dumbbell bar, the clamp of dumbbell plate and solid dumbbell sheet, described dumbbell bar is provided with the catch ring stoping dumbbell plate to slide to the dumbbell bar other end, rectangular resistance block is provided with outside catch ring, described dumbbell plate comprises balance weight body and is arranged on the ring protection body of its periphery, it is protruding that balance weight body periphery is provided with anticreep integrated with it, described protective is coated in anticreep projection, described balance weight body is bearing arrangement, and it can only one-directional rotation, balance weight body madial wall is provided with groove, described stopper embeds in groove.
As optimization: described stopper is four pieces, and within one week, be uniformly distributed along dumbbell bar.
The beneficial effects of the utility model: the utility model can in sport and body-building and athletics sports in the training of wrist and the quick strength of arm, single direction rotation can be carried out according to predetermined direction, responsiveness can be improved, accelerate practice frequency and reduce chance of injury.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of dumbbell bar of the present utility model;
Fig. 3 is the structural representation of disc of the present utility model.
Detailed description of the invention
As Fig. 1, shown in 2 and 3, a kind of single direction rotation dumbbell of tempering wrist and the quick strength of forearm, comprise dumbbell bar 1, the clamp 3 of dumbbell plate 2 and solid dumbbell sheet, described dumbbell bar 1 is provided with the catch ring 1-1 stoping dumbbell plate 2 to slide to dumbbell bar 1 other end, rectangular resistance block 1-2 is provided with outside catch ring 1-1, described dumbbell plate 2 comprises balance weight body 2-1 and is arranged on the ring protection body 2-2 of its periphery, balance weight body 2-1 periphery is provided with the protruding 2-3 of anticreep integrated with it, described protective 2-2 is coated on the protruding 2-3 of anticreep, described balance weight body 2-1 is bearing arrangement, and it can only one-directional rotation, balance weight body 2-1 madial wall is provided with groove 2-4, described stopper 1-2 embeds in groove 2-4, above-mentioned stopper 1-2 can be four pieces, and within 1 one weeks, be uniformly distributed along dumbbell bar.
After the utility model installs, due to adding of one-direction bearing structure, when practising, select to grip dumbbell bar according to the direction of rotation imagined in advance, due to the feature of unilateral bearing, wrist and arm can overcome the resistance that dumbbell plate is formed on the direction had an effect, when wrist and arm do return action, same because the feature of unilateral bearing, the resistance of dumbbell plate can significantly reduce, the origination action being conducive to quickly recovering to exercise enters action exercise next time, thus accelerate operating frequency, improve exercise efficiency, more meet the special requirement of the quick strengthening exercise of a lot of project, decrease the severe friction to palm caused due to the inertia of dumbbell plate when doing fast return action simultaneously, reduce the probability that palm is injured, ensure the safety of practitioner better.
Claims (2)
1. temper the single direction rotation dumbbell of wrist and the quick strength of forearm for one kind, comprise dumbbell bar, the clamp of dumbbell plate and solid dumbbell sheet, it is characterized in that: described dumbbell bar is provided with the catch ring stoping dumbbell plate to slide to the dumbbell bar other end, rectangular resistance block is provided with outside catch ring, described dumbbell plate comprises balance weight body and is arranged on the ring protection body of its periphery, it is protruding that balance weight body periphery is provided with anticreep integrated with it, described protective is coated in anticreep projection, described balance weight body is bearing arrangement, and it can only one-directional rotation, balance weight body madial wall is provided with groove, described stopper embeds in groove.
