Abstract

The utility model discloses a dumbbell easy to adjust in weight. The dumbbell comprises a dumbbell rod and dumbbell assemblies symmetrically arranged at the two ends of the dumbbell rod. Each dumbbell assembly comprises a shell with an opening, an electric magnet arranged on the inner side of the shell, a dumbbell piece arranged in the shell and attracted onto the electric magnet and a positioning block arranged at the bottom of the shell. A semi-circular closed block is arranged at the position of each opening and forms a whole with the corresponding shell, a semi-circular closed groove is formed in each closed block, the radius of the closed grooves is larger than that of the openings, a closed plate is arranged in each closed groove in a matched mode, the openings are closed by the closed plates, the shells are fixedly connected with the dumbbell rod, and switches for controlling the electric magnets are arranged on the faces, facing the dumbbell rod, of the shells. The dumbbell easy to adjust in weight can be placed stably, and weight adjustment is achieved more conveniently.

Description

A kind of dumbbell that is easy to regulating weight

Technical field

The utility model relates to a kind of dumbbell that is easy to regulating weight.

Background technology

Dumbbell is that a kind of for strengthening the simple equipment of muscle strength training, it is simple in structure, easy to use, and reasonably use can be played good train on, welcome by vast fitness enthusiasts.Current dumbbell parts by weights is Multiple Type, and along with the increase of practice periods, its weight also increases gradually, and because its weight is generally non-adjustable, this just causes purchasing multiple dumbbells, has increased acquisition cost and placement space.In addition, two iron tyres of dumbbell are circular at present, when placement, easily roll.

And the dumbbell of existing adjustable weight, its structure is roughly the several dumbbell plates of many placements on dumbbell bar, is then fixed by nut, and the dumbbell plate dismounting of this structure need to be by instruments such as spanners, and very trouble, so be not suitable for promoting the use of.

Summary of the invention

The technical problems to be solved in the utility model is to provide one and puts stablely, and weight regulates the more convenient dumbbell that is easy to regulating weight.

For addressing the above problem, the utility model adopts following technical scheme:

A kind of dumbbell that is easy to regulating weight, comprise dumbbell bar, and be symmetricly set on the component of dumb bells at dumbbell bar two ends, described component of dumb bells comprises that one has the shell of opening, and setting electromagnet inside the shell, and arrange in the enclosure, and be adsorbed on the dumbbell plate on described electromagnet, and be arranged on the locating piece of outer casing bottom, described opening part is provided with a semicircular sealing piece, described sealing piece and shell are an entirety, in described sealing piece, there is a semicircular enclosed slot, the radius of described enclosed slot is greater than opening radius, in described enclosed slot, be combined with a closure plate, described closure plate is sealed described opening, described shell is fixedly connected with dumbbell bar, described shell surface is provided with a switch of controlling described electromagnet in the side of dumbbell bar.

As preferred technical scheme, the opening direction of described enclosed slot and locating piece opposite direction.

As preferred technical scheme, described locating piece is circular cone, and one end that its sectional area is less is glued on shell, and one end that sectional area is larger contacts with ground, and locating piece is that rubber is made.

As preferred technical scheme, on the outer surface of described shell, be coated with the wear-resistant sleeve that one deck rubber is made.

As preferred technical scheme, described dumbbell bar is dolioform.

As preferred technical scheme, described dumbbell plate is iron plate.

The beneficial effects of the utility model are: in the time that needs increase dumbbell overall weight, only need to close electromagnet, dumbbell plate is placed in shell by opening, restarting electromagnet can realize fixing, weight regulates very convenient, can prevent when electromagnet surprisingly lost efficacy by set closure plate simultaneously, and inner dumbbell plate drops out and injures person taking exercise by a crashing object, make this device fixing more convenient by set locating piece, can arbitrarily not roll.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the side view of shell;

Fig. 3 is the cutaway view of shell;

Fig. 4 is the top view of shell.

The specific embodiment

below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Consult Fig. 1, Fig. 2, a kind of dumbbell that is easy to regulating weight shown in Fig. 3 and Fig. 4, comprise dumbbell bar 1, and be symmetricly set on the component of dumb bells at dumbbell bar 1 two ends, described component of dumb bells comprises that one has the shell 2 of opening, and be arranged on the electromagnet 3 of shell 2 inner sides, and be arranged in shell 2, and be adsorbed on the dumbbell plate 4 on described electromagnet 3, and be arranged on the locating piece 5 of shell 2 bottoms, described opening part is provided with a semicircular sealing piece 6, described sealing piece 6 is an entirety with shell 2, in described sealing piece 6, there is a semicircular enclosed slot 601, the radius of described enclosed slot 601 is greater than opening radius, in described enclosed slot 601, be combined with a closure plate 7, described closure plate 7 is sealed described opening, described shell 2 is fixedly connected with dumbbell bar 1, described shell 2 is provided with a switch 301 of controlling described electromagnet 3 in the side of dumbbell bar 1.

Wherein, the opening direction of described enclosed slot 601 and locating piece 5 opposite directions.

Described locating piece 5 is circular cone, and one end that its sectional area is less is glued on shell 2, and one end that sectional area is larger contacts with ground, and locating piece 5 is made for rubber.

On the outer surface of described shell 2, be coated with the wear-resistant sleeve (not shown) that one deck rubber is made.

Described dumbbell bar 1 is dolioform.

For described dumbbell plate 4 is iron plate.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
