Abstract

The utility model relates to the technical field of timing switches. The timing switch is characterized in that the circuit is provided with two supply switch contacts, which are controlled by a cam wheel, a supporting rod, a return spring and mechanical alarm clock components. The cam wheel is fixedly arranged on the spiral spring of the mechanical alarm clock. One end of the supporting rod is connected with the power switch contacts, and the other end of the supporting rod is connected with the return spring. The supporting rod is fixedly arranged on a support stand, and the support stand is a supporting point of the supporting rod. The timing switch has the advantages of simple structure, low cost, wide range of application, optionally adjustable interval time of switching on and switching off, etc.

Description

Multifunctional timing switch

The utility model relates to a kind of timing switch technical field.

Existing timing switch machinery arranged with two kinds of electronics, the timing switch of machinery can not arbitrarily be adjusted the blanking time of open and close with people's will, and is extremely inconvenient for the user, electric timing switch complex structure, cost height, extensively popularization and application, and function singleness.

The purpose of this utility model is a kind of multi-functional timing switch of design, this timing switch has simple in structure, cost is low, can arbitrarily adjust the advantages such as blanking time of open and close during use with people's will, it is widely applicable for the technical field of various electrical equipment timing open and close in worker, agricultural production and the people's lives, the best product of especially numerous aquarists or specialist.

The utility model is finished by following technical scheme.This multi-functional timing switch has a circuit loop, in this circuit loop, be provided with Be Controlled electrical equipment, power supply, it is characterized in that in circuit loop, also being provided with two mains switch contacts, two mains switch contacts are controlled by parts such as cam, pole, return spring, mechanism's alarm clocks, cam is packed on the clockwork spring handle of mechanical alarm clock, one end of pole links to each other with a mains switch contact, the other end of pole is connecting return spring, pole is packed on the support, and support is a fulcrum of pole.Be Controlled electrical equipment is the controlled regularly electrical equipment of open and close that need, as the motor of water pumper, and the electric heater of the specialist of breeding fish, oxygen therapy device, home-use ventilation fan etc.Power supply is exactly the power supply of Be Controlled electrical equipment.Mains switch is played in the mains switch contact in circuit loop, when two mains switch contact junction were incorporated into one, then the power supply of Be Controlled electrical equipment was switched on, otherwise then is cut off.Length design according to open and close blanking times on the cam has several plush coppers, cam is packed on the handle of clockwork spring of mechanical alarm clock, test according to reality, the clockwork spring of mechanical alarm clock rotated a circle in per eight hours, therefore this cam is under the clockwork spring of mechanical alarm clock drives, also be per eight hours rotation one circles, plush copper quantity setting on the cam is many more, then the open and close of Be Controlled electrical equipment are short more blanking time, the number of times of open and close is many more, otherwise the quantity of plush copper is few more, and then open and close are just long more blanking time, and the number of times of open and close is just few more.As only establishing a plush copper on the cam, then its interval open and close in eight hours once; As establishing four cams on the cam equably, then represent open and close in per two hours once, by that analogy.Plush copper on the cam is to promote pole to swing a contact that makes power-off along support, and plush copper is long more along cambered surface, and it is just long more that then it makes the time of power-off, otherwise just short.Pole is the bar of a strip, and its most handy nonconductive material is made, and pole is like a lever, and its fulcrum is exactly a support.In the use, when the plush copper of cam was withstood that end that has the mains switch contact, then contact, two mains switch places was in closed condition; As time goes on, when the plush copper of cam turns over the recess that arrives between plush copper and the plush copper, because the effect of return spring, make the mains switch contact of the pole other end with another mains switch contact in the circuit, combine firmly, make the power connection in the circuit loop, make Be Controlled electrical equipment be in opening, circulate with this, just regularly open and close of control apparatus effectively.Return spring is a spring that makes the pole yaw, by elastic force two mains switch contacts can be combined tightly.Mechanical alarm clock is the power set of cam rotation, also is the device of control cam rotating speed, and the clockwork spring handle of mechanical alarm clock rotates a circle, and then cam also rotates a circle, and they rotate a circle is eight hours.Support and spring can be fixed on the housing.In order to make the plush copper on the cam can withstand an end of pole tightly, a boss is established in the contact position that is preferably in the plush copper of pole and cam, and plush copper and boss just can hold out against tightly mutually during use, and two mains switch contacts are thrown off fully, thus powered-down.

During use, according to opening of Be Controlled electrical equipment, close the difference of blanking time, select more suitable cam, be fixed in then on the clockwork spring of mechanical alarm clock, tighten the clockwork spring of mechanical alarm clock, in circuit loop, Be Controlled electrical equipment and power circuit are connected, along with the clockwork spring of mechanical alarm clock slowly rotates, cam is also rotated, when the plush copper of cam is withstood pole, then with two mains switch contacts separately, make the Be Controlled appliance cut-off, quit work, after plush copper was got around, pole made two mains switch contact junction lump together again by the effect of return spring, makes power connection in the circuit loop, make Be Controlled electrical equipment operate as normal, circulate with this.

This multifunction switch has simple in structure, and cost is low, can arbitrarily adjust the blanking time of its open and close with people's will, uses many advantages such as easy to operate.Its restriction scope of application is that each blanking time of open and close can not be above eight hours.

Fig. 1 is a structural representation of the present utility model, also can be used as example structure schematic diagram of the present utility model.

Be described in detail below in conjunction with accompanying drawing.

In the accompanying drawing: 1 power supply; 2 mains switches; 3 mains switch contacts; 4 boss; 5 cams; 6 supports; 7 return springs; 8 inflator pumps; 9 breather lines; 10 poles; 11 plush coppers.

Be Controlled electrical equipment in this accompanying drawing is inflator pump (8), cam (5) has and is provided with four plush coppers (11) equably, be two hours blanking time that is each open and close, for safer in using, also established a mains switch (2) in circuit loop.Adopt this timing switch regularly to fill two hours gas, stop again then, successively circulation every two hours to fish jar.
