The utility model is suitable for positioning whistle device of electric siren, the foreign sundries are prevented from coming into the whistle cavity when the electric siren is not whistling.
Description
Technical field
The utility model relates to the motor siren structure member, specifically is meant the locating device when warning horn ring wheel stops ringing.
Background technology
Motor siren as the air defence warning device, plays ring by driven by motor ring wheel high-speed rotation.Offer the sound window, the ring wheel periphery is provided with the blade with quantity such as sound window with circumferentially dividing equally on the motor siren shell.For preventing that motor siren stop ringing state external impurities, flying bird from entering in the tymapanum from the sound window, should make warning horn stop ring state ring wheel and be in week fixed angle position upwards, make the ring impeller blade just in time keep off the sound window that closes the warning horn shell.For this reason, ring wheel locating device is set, making the ring wheel is not to be in circumferential random site when stopping ringing, but is in described fixed angle position.
Ring that known technology adopted wheel locating device has mechanism's formula structure, more complicated.
Summary of the invention
Technical problem to be solved in the utility model is that simple structure is released in design, a kind of new ring wheel locating device of good positioning effect, the ring wheel is in circumferential fixed angle position automatically when making motor siren stop ringing, this position ring impeller blade just in time keeps off and closes shell sound window, prevents that external impurities from falling in the tymapanum by the sound window.
Its special character of the technical solution adopted in the utility model is to have corresponding price fixing spare and the carousel that is provided with, price fixing spare and carousel respectively have shell, offer magnetism putting hole with circumferentially dividing equally on the shell bottom surface, the built-in magnetic patch that is provided with of magnetism putting hole, be provided with sleeve gasket in the described shell and rely on magnetic patch, shell is provided with fixing threaded hole.
Magnetism putting hole on the described shell bottom surface has ten, is circular port, respectively is embedded with the magnetic patch of cross section circle in the hole.
Magnetism putting hole also can be eight, 12.
The shell of described price fixing spare, carousel can be a same structure, and the sleeve gasket that is provided with in it also can be a same structure.The shell of price fixing spare, carousel also can be that structure is different, and also structure is different for sleeve gasket in it.
Set fixing threaded hole can be that the outer tang of periphery is along last set fixing threaded hole on the shell of price fixing spare of the present utility model; Set fixing threaded hole can be that nearly set its periphery of fixing threaded hole of perisporium has the pipeline section structure in the shell on the shell of carousel, corresponding to having corresponding indent on its perisporium of the described sleeve gasket of this pipeline section structure.
Price fixing spare of the present utility model, carousel and interior set sleeve gasket thereof can be made of plastic.
It is corresponding and to keep a gap, this gap can be 1～2mm that the state of installing and using price fixing spare of the present utility model and carousel are provided with the one side of magnetic patch.Price fixing spare is fixed in a support set in the motor siren, and carousel is fixed in the ring wheel.Fixing threaded hole on the described shell is made this fixedly usefulness exactly.
Magnetism putting hole on the described shell bottom surface is designed to the smaller stepped hole of collar extension, and described magnetic patch is in shell direction embedding from inside to outside, and the sleeve gasket in the shell relies on magnetic patch makes it can inwardly not emerge in magnetism putting hole.Sleeve gasket and shell can be through the bolt combinations.
The utility model is owing to be provided with price fixing spare and carousel, respectively is provided with the magnetism putting hole circumferentially divided equally on its shell and is provided with magnetic patch in it, and shell is provided with fixing threaded hole.So price fixing spare of the present utility model is fixed in the support in the motor siren, carousel is fixed in the ring wheel, it is corresponding and keep a gap that price fixing spare, carousel are provided with the one side of magnetic patch, carousel rotated with the ring wheel when warning horn played ring, price fixing spare maintains static, the attract each other effect of power of corresponding magnetic patch in price fixing spare, carousel when stopping ringing, make carousel be in the fixed angle position together with the ring wheel, this position just in time makes the blade on the ring wheel keep off the sound window that closes on the warning horn shell, prevents that external impurities, flying bird etc. from entering tymapanum.The utlity model has simple in structure, the characteristics of accurate positioning.
