An overvoltage protective circuit, a secondary voltage stabilizer, filtering network, a time control magnifying driving circuit, and an indicator circuit with timing glittering operation. The utility model has the advantages of compact structure, simple installation, convenient installation, low cost, accurate timing, high reliability, and good versatility. Besides, the utility model does not need any peripheral transfer element, can normally work under the condition of the large voltage fluctuation, and can display and remain the accumulative hours of the operation of the motor vehicles under the state of poweroff.
Description
The utility model relates to a kind of formula motor vehicle timing that adds up with table, is particularly suitable for the engine of engineering machinery, earth moving machinery, tractor etc. and the stopwatch that adds up that complete machine work timing is used.
Domestic various motor vehicles such as engineering machinery, earth moving machinery etc. mostly adopt mechanical type equivalent stopwatch at present, this stopwatch is that the revolution needs equivalent conversion according to motor car engine operation demonstrates equivalent working time, and the drive mechanism complexity of this table, easy to wear, and to pass through peripheral transmitting elements such as speed reduction unit, flexible axle and be connected, numerous and diverse, use inconvenience is installed with equipment under test.The present electronic type stopwatch that uses, though directly the service hours of display machines motor vehicle engine need peripheral transmitting elements such as speed reduction unit, rotating shaft and driver to be connected with equipment under test equally, because of its installation, the maintenance numerous and diverse, manufacturing cost is higher, so be difficult for applying.
The purpose of this utility model is to provide a kind of improved stopwatch that adds up.This list structure compactness, installation is simple, convenient, does not need other any peripheral transmitting element can add up the working time of measuring machine motor vehicle engine.Accurate timing is reliable, and versatility is good.
The purpose of this utility model is achieved in that this stopwatch is made up of panel, housing and the time base circuit control panel, the solenoid actuated formula mechanical counter that are contained in the housing.Be assembled with by diode D on the time base circuit control panel
