Description

The music instrument of hoisting a flag automatically

The utility model relates to a kind of flagraising device, the particularly music instrument of hoisting a flag automatically.

Now, people will carry out the flagraising activity when carrying out some serious ceremonies, and large-scale flagraising device generally is a stationary installation, and inconvenience is moved, and small-sized flag hanging device hangs for fixing, special field need be set put, otherwise lose seriousness.The applicant finds that the small-sized device of movably hoisting a flag brings convenience carrying out relevant ceremony to people, and can receive the fixedly same effect of flagraising device.Popular on the market flag hanging device can not reach the identical effect of flagraising instrument at present, therefore is necessary to make improvements.

The purpose of this utility model is, at above-mentioned the deficiencies in the prior art, improves, and proposes and the design music instrument of hoisting a flag automatically.

Technical solution of the present utility model is, adopt base, flagpole, flagpole is contained on the base, pulley is equipped with in the flagpole end, the rope of being furnished with flagraising usefulness on the pulley, it is characterized in that, adopted and the matching used music apparatus for automatically lifting of the rope of flagraising usefulness, it is by motor, power wheel, control circuit is formed, motor cooperates with power wheel, power wheel cooperates with the rope of flagraising usefulness, and control circuit cooperates with motor, and control circuit is by switch, musical film, delay action circuit breaker, the battery series connection, divide the two-way conversion to connect between switch and the motor, wherein one the tunnel be connected to the not circuit that commutation is used, the output terminal and the loudspeaker of musical film connect, and motor is fixed in the base, and control circuit is contained in the base.

Delay action circuit breaker is selected the isolating switch of RC series connection delay circuit structure for use.

Protect on the base and block, protect to block and form by fixed leg and chain link cooperation.

Ornamental step is arranged around the base.

Base is a square structure, also can select circular configuration for use.

Basic functional principle of the present utility model is, starting switch, control circuit work, musical film produces music electrical signal and sends musical composition by loudspeaker, in this simultaneously in musical composition sound, motor rotates and makes by the rotation axis that is mated the rope motion of flagraising usefulness, so the flag that is suspended on the flagraising rope moves upward along with the rope of flagraising usefulness, till being raised to flagpole upper end and being stopped, when chronotron open circuit delay time be set arrive after, delay action circuit breaker disconnects, and motor stops operating, and the utility model quits work.When the needs flag lowers, again by the switch commutation, make the motor counter-rotating, the flag that is suspended on flagpole top so will be reduced to the lower end of flagpole along with the descending motion of the rope of flagraising usefulness.The time constant that chooses delay action circuit breaker is in the time range of delay action circuit breaker permission the time of the move distance of flag rising or decline preferably.

Advantage of the present utility model is, designs exquisitely, reasonable, small and exquisite, attractive in appearance, can satisfy the needs of holding flagraising ceremony of people when not having fixing large-scale flagraising device, because volume is little, be convenient to move, brought many convenience, can produce the same effect of large-scale flagraising device to people.It is applied, and provides a kind of economical and practical device for the public holds various ceremonies, and along with the reinforcement to the national education activity, positive role of the present utility model will better be embodied and use.
