Description

Dumbbell with sonic generator

The utility model is meant a kind of dumbbell with sound-producing device especially relevant for a kind of motion dumbbell.

After work busy in the modern times, people increase gradually to the demand of motion, and dumbbell belongs in various sports equipment that volume is little, simple structure, utensil easy to use, is therefore extensively generally used.Known dumbbell mostly only lays particular emphasis on weight training, that is includes the dumbbell combination of multiple Different Weight, and the user chooses the weight that meets according to physical ability situation, therefore commonly uses dumbbell and mostly constructs stiffly, lacks innovation on the structure.Recently motion is often carried out simultaneously with amusement and recreation, that is has the effect of amusement and recreation at the volley, and reaches the motion purpose in amusement and recreation, and motion just is unlikely dull uninteresting like this, thereby has improved the enjoyment of motion, and exercise habit is able to lastingly.

Because the dumbbell of commonly seeing only provides a base unit weight merely, can't produce other amusement entertaining effect, therefore be difficult for causing common people's use interest, particularly teenager, children, if on color and sound equipment, cause their interest earlier, then more can attract their hobby for dumbbell exercise.

Main purpose of the present utility model promptly is to provide a kind of dumbbell with sound-producing device, with fabricated structure, make its inside be held sound-producing device, send the movement rhythm melody by the dumbbell end, or be called and produce dynamic music password, the trick health can be waved, to increase the pleasant sensation and the enjoyment of motion with rhythm music password.

A time purpose of the present utility model is to provide a kind of dumbbell with sound-producing device, and its load is lighter, and weight can suitably adjust, to be fit to young children's use.

For achieving the above object, the dumbbell that the utlity model has sound-producing device comprises a lever unit, hollow housing for plastic rubber ejaculate molding, be divided into upper shell and lower house, both shape symmetries all have semicircle profile, so that be combined into a round bar shape housing, its inside is provided with some spacers, and in order to the elements such as circuit board, battery, switch and loudspeaker of chimeric sound-producing device, its two ends are provided with screw thread; Two counterweight elements are two hollow plastic casings that shape is identical, and the one end is airtight spheroidal, and the other end has a circular hole, screw thread are arranged with on the screw thread that is screwed together in two ends, lever unit in the circular hole, and there is a dividing plate this circular hole inboard, and there is a through hole in dividing plate central authorities; One cover plate is a circular sheet, covers through hole on the dividing plate in order to engaging; Above-mentioned two counterweight elements are by pack into the counterweight material of suitable weight of this through hole, capping cover plate then, and recombinant is in these two ends, lever unit, then consist of a dumbbell, and can send rhythm sound by the sound-producing device in this lever unit.

Relevant the utility model detailed construction, function and characteristics can fully be understood by the detailed description of following examples conjunction with figs..

Fig. 1 is the three-dimensional exploded view of the dumbbell with sound-producing device of an embodiment of the utility model.

Fig. 2 is the combination stereogram of dumbbell shown in Figure 1.

Fig. 3 is the circuit diagram of the utility model sound-producing device.

See also Fig. 1 to Fig. 3.This dumbbell is made up of a lever unit 10, one sound-producing devices 20 and a counterweight element 30 three parts.

Lever unit 10 main members are a lower house 11, a upper shell 12 and a battery cover 13.Lower house 11 is the semicircle rod hollow housing of plastic rubber ejaculate molding, its central authorities are semicircle hull shape bar portion 111, its interior one-body molded have two battery trays that vertically stand 112 and two columns 113, its two ends are two bonding parts 114,115, all have pin thread 116 and small sircle hole 117, wherein vertically standing in the bonding part 114 has circuit panel seat 118, vertically is provided with a cylindrical column 119 in another bonding part 115; The shape of upper shell 12 and lower house 11 symmetries are identical semicircle rod hollow plastic casing, and its central authorities are bar portion 121, have a battery hole 122 and circular hole 123, and two ends are two bonding parts 124,125, also all have pin thread 126 and small sircle hole 127; Battery cover 13 is lived battery hole 122 in order to cover cap, has a grab 131 on it, to be sticked in the upper shell 12.

Sound-producing device 20 comprises members such as at least one battery 21 and two battery conductive sheets 22, a switch 23, phonation circuit plate 24 and loudspeaker 25.Wherein conducting strip 22 is inserted in the battery tray 112, battery 21 then can be embedded between the conducting strip 22, switch 23 is fixed in the bar portion 121, circuit board 24 is embedded in the slotted eye 118a of circuit board holder 118 and fixes, loudspeaker 25 are placed on cylindrical column 119 tops, are pushed down and are located by the inner face of upper shell 12 again.

Counterweight element 30 comprises two spherical hollow plastic cement spherical shell 30A, 30B that structure is identical, the end sealing of each spherical shell 30A or 30B, the other end has a circular hole, circular hole has an internal thread 32 and a dividing plate 33, there is a through hole 34 in dividing plate 33 central authorities, and the 180 degree places that are separated by, through hole 34 edges respectively have a breach 35; One cover plate 36 is circular plastic plate, and its external diameter should cover through hole 34 fully, and there are two grabs 37 at the one side 180 degree places that are separated by, make it just can be by breach 35 clip make cover plate 36 close through hole 34 in dividing plate 33 is inboard; In addition, be nested in the annular groove 39 of spherical shell 30A, 30B periphery with a rubber ring 38.

What will remark additionally in addition is, the circuit of above-mentioned sound-producing device 20 as shown in Figure 3, wherein the IC 1 on the circuit board 24 is music rhythm or the music motion password by predetermined planning storing and setting, cooperate resistance R 1, capacitor C 1 and transistor Q1, when switch 23 is connected, will send Technic Beat music or music motion password by loudspeaker 25.

When the dumbbell of above-mentioned illustrated embodiment assembles, earlier conducting strip 22, switch 23, circuit board 24 and the loudspeaker 25 of sound-producing device 20 are installed on the precalculated position in the upper and lower casing, again upper and lower casing 12,11 is covered mutually and close, pass circular hole 123 with screw 41 then and be screwed together on the column 113, make upper and lower casing 12,11 strong bonded and make each element of sound-producing device be fixed in enclosure interior; Then via through holes 34 loads solid, particle or the fluid of suitable weight in two counterweight spherical shell 30A, 30B; again cover plate 36 spiral covers are lived this through hole 34 and held fixing with grab 37; at last these two counterweight spherical shells are screwed together on the screw thread 116 and 126 at lever two ends with screw thread 32 respectively; so not only finished the assembling of dumbbell; and two ends, upper and lower casing 12,11 combination back are snapped together more firmly, constitute a dumbbell that belongs to lightweight.

Dumbbell of the present utility model provides the basic exercise purposes of general dumbbell in the use, and can open battery cover 13 and pack battery 21 into and use its inner sound-producing device 20 that is provided with.When switch 23 is connected, send rhythmical music or motion music password by circular hole 127, so the user can wave dumbbell exercise along with music rhythm or password.This dumbbell even can be used as the apparatus of the orderly dancing campaign of the rhythm, thus more active purposes is provided.Therefore, dumbbell of the present utility model especially is fit to children or teenager and does the movement entertainment use, and making has entertainment effect in the motion, or reaches the purpose of motion in amusement.
