The novel combined-type timing apparatus is characterized in that the novel combined-type timing apparatus further comprises a first relay, a second relay, and a time-delay relay; the switch is connected in series between the conduction timer and one end of a power supply; the first relay, the second relay, the time-delay relay, and the indicating lamp are connected in parallel between the conduction timer and the other end of the power supply; a normally-opened switch of the first relay is connected in parallel with the two ends of the switch; a normally-closed switch of the first relay, a normally-opened switch of the time-delay relay, and the buzzer are connected in series between the two ends of the power supply; and a normally-opened switch of the second relay is connected to a controlled electric appliance. The substantial effects are that: the novel combined-type timing apparatus is simple in circuit, convenient in control, and capable of being rapidly assembled into equipment without timing devices; the timing length can be adjusted, an alarm can be sent out if time is out, the power supply of the controlled electric appliance can be automatically cut off, and thus the objective of timing control is realized; and the apparatus is very widely applied.

Description

A kind of novel combination type time set

Technical field

The utility model relates to a kind of time set, specifically, be a kind of for timing switch control and novel combination type time set that have warning function.

Background technology

In each industrial and mining enterprises, timing controlled when usually relating to the equipment operation, the smart machine of most has carried timing device, usage comparison is convenient, but this timing device can only be fixed on equipment and use, and often also only equipment self is had effect,, just be difficult to play a role not with for the industrial equipment of timing device for some.

In industrial application, usually there are a lot of equipment not to be with timing function, the workpeople usually wants a kind of timing device of easy and convenient disassembly, when needs equipment timing operation, this device can be assembled into fast, make it reach regularly effect, when not needing regularly, can easily this device be disassembled again, make the original situation of its maintenance equipment.

The shortcoming of prior art is: although easy timing switch can satisfy the demand, lack necessary warning and prompt facility, the workman is difficult in time control the operation conditions of equipment, usually because the overtime adverse consequences that causes.

The utility model content

In order to address the above problem, the utility model proposes a kind of novel combination type time set, the needs that both accorded with He freely assembled can be realized again the prompting of operating state and the warning that regularly finishes, thereby satisfy various commercial Application demands.

In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:

a kind of novel combination type time set, comprise switch, the energising timer, indicator light and buzzer, its key is: also comprise the first relay, the second relay and time-delay relay, described switch series be connected on energising timer and power supply an end and between, described the first relay of parallel join between the other end of energising timer and power supply, the second relay, time-delay relay and indicator light, described the first relay is provided with normally closed switch and normal open switch, the second relay is provided with normal open switch, time-delay relay is provided with normal open switch, the normal open switch parallel join of described the first relay is at the two ends of switch, the normally closed switch of described the first relay, the normal open switch of time-delay relay and buzzer are connected in series between both ends of power, the normal open switch of described the second relay is connected on controlled electric appliance.

Preferably, the delay time of described time-delay relay is 15～25 seconds, and delay time is the buzzer warning time, is used for caution staff equipment timing and arrives, and is convenient in time enter subsequent processing.

Preferably, the normal open switch of described the second relay is connected on the power line of controlled electric appliance as the mains switch of controlled electric appliance.When timing arrives, can automatic disconnection controlled electric appliance power supply, the arrestment operation reaches the timing controlled purpose.

Remarkable result of the present utility model is: circuit is simple, it is convenient to control, can be assembled to fast in the equipment that there is no timing device, timing is adjustable, and overtime the warning can be blocked the controlled electric appliance power supply automatically, reach the timing controlled purpose, the used time can also not disassemble easily, can be used as interim assembly ware and uses, and uses very extensive.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model and operation principle are described in further detail.

as shown in Figure 1, a kind of novel combination type time set, comprise K switch, energising timer T, indicator light L, buzzer Z, the first relay K 1, the second relay K 2 and time-delay relay KT, described K switch be serially connected in energising timer T and power supply an end and between, described the first relay K 1 of parallel join between the other end of energising timer T and power supply, the second relay K 2, time-delay relay KT and indicator light L, described the first relay K 1 is provided with normally closed switch K1-1 and normal open switch K1-2, the second relay K 2 is provided with normal open switch K2-1, time-delay relay KT is provided with normal open switch KT-1, the normal open switch K1-2 parallel join of described the first relay K 1 is at the two ends of K switch, the normally closed switch K1-1 of described the first relay K 1, normal open switch KT-1 and the buzzer Z of time-delay relay KT are connected in series between both ends of power, the normal open switch K2-1 of described the second relay K 2 is connected on controlled electric appliance.

In specific implementation process, the delay time of time-delay relay KT is made as 15～25 seconds.The normal open switch K2-1 of the second relay K 2 is connected on the power line of controlled electric appliance as the mains switch of controlled electric appliance.

Operation principle of the present utility model is:

K switch is generally the trigger button switch, switch conduction when pressing, and the rear switch of loosing one's grip disconnects, and energising timer T is adjustable energising timer, and power-off time is adjustable.Circuit as shown in Figure 1, in use, after both ends of power L, N connect electricity, press K switch, energising timer T conducts electricity work, begin to timing, this moment the first relay K 1, the second relay K 2, time-delay relay KT and indicator light L all electric, indicator light L lights, and indication equipment is started working.Because the first relay K 1, the second relay K 2 and time-delay relay KT get electric, make the closed formation of the normal open switch K1-2 self-locking of the first relay K 1, the first relay K 1 normally closed switch K1-1 disconnects, the normal open switch KT-1 of time-delay relay KT is closed, but buzzer Z does not still work, the normal open switch K2-1 of the second relay K 2 is closed, makes controlled electric appliance energising work.

when the overtime outage of energising timer T, the first relay K 1, the second relay K 2, time-delay relay KT and indicator light L all cut off the power supply, indicator light L extinguishes, indication equipment is out of service, due to the first relay K 1, the second relay K 2 and time-delay relay KT outage, make the normal open switch K1-2 of the first relay K 1 disconnect, the first relay K 1 normally closed switch K1-1 is closed, the normal open switch KT-1 time-delay of time-delay relay KT disconnected in 15～25 seconds afterwards, in delay time, the buzzer Z work of namely switching on, send alarm sound, the prompting timing is overtime, after time-delay finishes, the normal open switch KT-1 of time-delay relay KT disconnects, get back to initial condition, in this process, the normal open switch K2-1 of the second relay K 2 also gets back to off-state, make the controlled electric appliance outage quit work, finally reach time-controlled purpose.
