Abstract
The utility model relates to a heavy dumb-bell, comprising a bell spherical body and a bell handle. The basic improvement lies in that the bell spherical body adopts a double-layer structure, comprising an inner structure and an outer structure; the outer layer is a steel casing, and the inner layer is a lead-made sphere core. The structure has the advantages of larger weight-to-volume ratio, convenient practice, convenient carry and convenient adjusting of the weight of the dumb-bell compared with ordinary dumb-bells.
Description
The utility model relates to a kind of improved dumbbell, belongs to the athletic sports appliance technical field.
The dumbbell that uses in the general sports is that iron and steel is made, owing to will reach certain weight, dumbbell bell spheroid just needs certain volume, and weight is big more, and sphere volume is just big more, and this can hinder when exercise and carry out exercises, and causes easily and damage.Simultaneously, volume carries also inconvenient greatly when going out to exercise.
It is less that the purpose of this utility model provides a kind of volume, easy to carry, can reach the dumbbell of constant weight requirement simultaneously again.
The purpose of this utility model is achieved in that
The heavy dumbbell of a kind of hard iron, it comprises bell spheroid and bell 3, and its basic improvements are: described bell spheroid is interior outer double-layer structure, and outer 2 is iron shells, and internal layer 1 is plumbous matter ball core.
The heavy dumbbell of above-mentioned hard iron, described bell spheroid and bell also can be demountable structures being cast into one, the ball core of bell spheroid internal layer 1 can be graininess or plates.
The heavy dumbbell of above-mentioned hard iron adopts between described bell spheroid and the bell handle to be threaded, and perhaps adopts tight fit to peg graft, and uses bolting.
Dumbbell according to the utility model is made can reduce the volume of dumbbell spheroid greatly keeping dumbbell to have under the condition of identical weight.This structure makes it compare with common dumbbell, has bigger w/v, and is easy to use and carry.If adopt demountable structure, the weight that then can regulate dumbbell easily is convenient to different personnel or is practised by different needs.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the dumbbell partial sectional view;
Fig. 2 is a kind of partial sectional view of detachable dumbbell structure;
Fig. 3 is the partial sectional view of another kind of detachable dumbbell structure;
Starting point of the present utility model is to adopt the material of different specific weight to make the ectonexine of dumbbell, thereby can keep the outward appearance of dumbbell, can strengthen its weight again, and avoid plumbous pollution.
In Fig. 1, bell spheroid skin 2 adopts ferrous materials to make, and the plumbous material of bell spheroid internal layer 1 usefulness is made, and skin 2 is fixed as one 3 with bell.
In Fig. 2, bell spheroid outer 2 is connected 3 usefulness helicitic textures with bell, and detachably, the plumbous matter ball core of internal layer 1 is a graininess, can take out.
In Fig. 3, bell spheroid outer 2 is 3 the form of sleeve tight fit with bell, uses bolting.
Ectonexine in the utility model also can adopt other material manufacturing.
Claims (3)
1. heavy dumbbell of hard iron, it comprises bell spheroid and bell [3], and it is characterized in that: described bell spheroid is interior outer double-layer structure, and outer [2] are iron shells, and internal layer [1] is plumbous matter ball core.
2. dumbbell according to claim 1 is characterized in that: described bell spheroid and bell also can be demountable structures being cast into one, and the ball core of bell spheroid internal layer [1] can be graininess or plates.
