Description

Body-building, strong and handsome dumb-bells

The utility model relates to a kind of sports apparatus, specifically a kind of fitness and body-building bell.

Dumbbell is the general apparatus that has sports, and also is the important apparatus of body-building exercise, does activities such as dumbbell exercises through dumbbell commonly used, can make the up to a hundred muscle at two arms, chest and the back of human body become flourishing, can make people's physique strong and vigorous and graceful.

Existing dumbbell all is a fixed weight, and it generally is made of metal.This traditional dumbbell uses and tends to contaminated after a period of time and get rusty, and uses extremely unhygienicly, and it can't regulate weight according to the physical condition in everyone each period, function singleness, brought inconvenience to exercise, especially youngsters and children should not use, and has influenced train on.

The purpose of this utility model provides a kind of adjustable heavy fitness and body-building bell, reach by increasing or reduce balancing weight in the device, everyone regulates weight at any time according to health, or by transferring the heavy exercise needs that can satisfy the people of different fitness, simultaneously, by structure is carried out appropriate design, make the fitness and body-building bell not only have the effect of traditional dumbbell exercising way, and also have the push-up exercise effect.

For reaching above-mentioned purpose, the utility model is achieved like this: a kind of fitness and body-building bell, it comprises hollow lever, inner sheath and oversheath, it is characterized in that being provided with axle in the hollow lever, the end of axle is provided with clamp nut, balancing weight and dismounting nut, inner sheath is by clamp nut and tight end at hollow lever, oversheath and inner sheath matched in clearance, and by dismounting nut and tight top in axle, the fit dimension of said inner sheath and oversheath, fit shapes is identical, on the maximum outer wall of inner sheath, have the circular orientation step, be with retaining ring on this step.

Hollow lever in the device, inner sheath, oversheath, dismounting nut can use plastics once molding formed.

The utility model has the advantages that the fitness and body-building bell is reasonable in design, simple in structure, it integrates body-building, fitness, strong mind, entertaining changes, and not only has the effect of traditional dumbbell exercising way, and also has the push-up exercise effect, has dual-use function.In addition, the fitness and body-building bell is because the versatility of design, its sheath profile can adopt multiple shape, and by the sound that rustles that the sand grains that fills in the hollow lever sends in motion process, has improved person taking exercise's interest, simultaneously, it is not subjected to the restriction of field boundary ground, and the graceful health of outward appearance also can follow child growth to regulate weight voluntarily, transfer easy accessibility when weighing, use peaceful reliable.

Below the utility model is further explained for the embodiment that is given with reference to the accompanying drawings.

Fig. 1, the structural representation of expression fitness and body-building bell.As can be seen from the figure the fitness and body-building bell is made up of retaining ring (1), inner sheath (2), axle (3), oversheath (4), balancing weight (5), clamp nut (6), dismounting nut (7), hollow lever (8).Its central shaft (3) passes hollow lever (8) and inner sheath (2) matched in clearance vertically, by clamp nut (6) with inner sheath (2) and tightly in the end of hollow lever (8), the end of axle (3) is with balancing weight (5) and oversheath (4), by dismounting nut (7) that it is also tight, on the maximum outer wall of inner sheath (2), have the circular orientation step, be with retaining ring (1) on the circular orientation step, retaining ring (1) can be made with rubber, can play the security protection effect when use is careless.In order to strengthen and improve user's exercise interest, in hollow lever (8), can fill an amount of sand grains, so that can send the sound of " rustling ".

Fig. 2, Fig. 3, Fig. 4 have provided three kinds of shapes perpendicular to axis direction of the maximum profile of oversheath (4) in the device respectively.Fit dimension, the fit shapes of inner sheath (2) (referring to Fig. 1) and oversheath (4) are identical.

Balancing weight in the device (5) can combine with some blocks of sheet metals, transfers when weighing, and screws off dismounting nut (7) earlier, pull down oversheath (4), unload or load onto balancing weight (5) according to the physical efficiency needs then, refill oversheath (4) at last, screw dismounting nut (7).
