Abstract

The utility model discloses a chest-expander for children body-building with can generate musical sound and light. The chest-expander for children body-building comprises an external sleeve, a pulling cylinder, springs, a music integrated package, a loud-speaker and a small electric bulb. Children can be physically strengthened by playing the chest-expander for children body-building. The chest-expander for children body-building itself is an interesting sound and light toy.

Description

Chest-expander for children body-building

The utility model relates to a kind of body-building chest developer, particularly a kind of band music, irradiative children's chest expander.

Existing chest expander generally is to use for the adult, can be not acoustic luminous yet, and relatively more dull, be not suitable for children and use.

Task of the present utility model is the chest expander that a kind of children special-purpose will be provided, and it also is a kind of interesting acousto-optic toy not only as the physical training equipment of children's body-building.

Task of the present utility model is finished as follows: when the handle of holding the chest expander both sides when both hands draws back relatively, and camber of spring on the one hand, two of the slide front end contacts are by the lamellule on the outer casing inner wall on the other hand.At this moment, electronic circuit is connected, and sends music and light.Both hands do not spur, because the spring of distortion will restore to the original state, and the slide origin-location in the overcoat of promptly withdrawing.Like this, slide has just been finished once and has been come and gone.The tensile strength of above-mentioned spring is moderate, guarantees children's exercise requirement.The utility model is easy to use, and conventional material is easily purchased, and when the example structure that describes in detail below adopting, product is easy to make.Produce music signal with music-integrating block, adopt the CIC2850 integrated package of the single straight cutting plastic packaging of 9 pin, after the connection primary power source disconnects, the playback of delaying time, microphone device adopts small-bore loudspeaker, and luminescent device adopts bulb.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the utility model schematic diagram.

Fig. 2 is that the utility model is luminous, the sounding schematic diagram.

With reference to Fig. 1, spring ［ 5 ］ is installed between chest expander overcoat ［ 4 ］ and the slide ［ 2 ］.Vocal hole ［ 4 ］ and handle ［ 9 ］ are arranged on the end face of overcoat ［ 4 ］.Battery ［ 3 ］ is equipped with in slide ［ 2 ］ inside, music-integrating block ［ 6 ］ and speaker ［ 7 ］.The exposed parts of slide ［ 2 ］ has handle ［ 1 ］, and the other end has sounding aperture ［ 13 ］ and bulb ［ 8 ］, and on a certain position of doing to move back and forth with overcoat ［ 4 ］ inwall metallic contact ［ 11 ］ and ［ 12 ］ is arranged.With reference to Fig. 2, contact ［ 11 ］ is connected with capacitor and bulb.Contact ［ 12 ］ and loudspeaker, music-integrating block 2850 the 5th pin, anode is connected.Continuation is with reference to Fig. 1, and metallic contact ［ 11 ］ and ［ 12 ］ are nearer apart, during actual fabrication, and general desirable 5-10 millimeter.In the appropriate location that this two contact back and forth passes through, the little sheet metal of a slice ［ 10 ］ is arranged at chest expander overcoat ［ 4 ］ inwall, its length should be greater than distance between two contacts.When two contacts passed through it together, sound and light were sent in the electronic circuit conducting.

Among Fig. 2, capacitor volume is got 0.5 microfarad, and the resistance of resistor is got 68 kilo-ohms.

Claims

1, children's chest expander of being made up of overcoat [4], slide [2], spring [5] and music-integrating block [6] is characterized in that:
