Description
Technical field
The utility model relates to a kind of timing device, and is particularly a kind of for circuit mechanical type autotimer of many times regularly.
Background technology
At present, common mechanical timing switch can only be carried out a control command, namely simply regularly closes, set the time after timer start working, arrive the time point timer of setting and close, can not satisfy the requirement that people finish automatically to a plurality of control commands.The already present timing switch that can finish a plurality of instructions mostly is the high-end devices of built-in microcomputer in the market, involves great expense and harsh to the operational environment requirement, is difficult to popularize.In science and technology continuous progressive today, people progressively improve for the requirement of automation, therefore design a kind of that carry out a plurality of instructions and cheap timing switch and be society in the urgent need to.
The utility model content
The purpose of this utility model provides a kind of control command and simple in structure of can finishing repeatedly, is used for circuit mechanical type autotimer of many times regularly.
For reaching above purpose, the technical solution adopted in the utility model is as follows: comprise two power electrode-electrodes one and electrode two, be in series with plural switch between two electrodes, described switch is connected with respectively the mechanical timing switch of its closure of control, disconnection.
Described switch is two contact switch-contact switchs one and contact switch two, electrode one is connected with the moving contact of contact switch one, electrode two is connected with the fixed contact of contact switch two, the fixed contact of contact switch one is connected with the moving contact of contact switch two, and the moving contact of two pairs of contact switchs links to each other with mechanical timing switch respectively.
Described mechanical timing switch is by knob, be sleeved on the scroll spring that drive knob rotates on the rotation axis, the cam, the buffer gear cold group that is connected with cam and the ratchet that are enclosed within the driving moving contact motion on the rotation axis form, and the sheet that pulls out that matches with ratchet also is installed in mechanical timing switch.
Mechanical type autotimer of many times described in the utility model, the plural switch of series connection between two electrodes is by closure, the disconnection of mechanical timing switch control tandem tap, the purpose of control command is finished repeatedly in realization, simple in structure, practical, be fit to large-scale popularization and use; Use mechanical timing switch independently to preset, control switch is realized repeatedly the function of control command at closure, the opening operation of different periods respectively, finishes conducting or disconnection control a time period to circuit.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Such as Fig. 1, a kind of mechanical type autotimer of many times is disclosed, comprise electrode one a and electrode two b, series connection contact switch 1 and contact switch 24 between two electrodes, contact switch 1 is connected with mechanical timing switch 1, contact switch 24 is connected with mechanical timing switch 22, by the closed and disconnected operation of mechanical timing switch control contact switch.
Such as Fig. 2, concrete circuit connection structure is, electrode one a is connected with the moving contact 1 of contact switch 1, electrode two b are connected with the fixed contact 2 13 of contact switch 24, the fixed contact 1 of contact switch 1 is connected with the moving contact 2 12 of contact switch 24, moving contact-the moving contact 1 of two pairs of contact switchs and moving contact 2 12 link to each other with the cam 1 of mechanical timing switch 1 and the cam 27 of mechanical timing switch 22 respectively.
As shown in figures 1 and 3, mechanical timing switch comprises the knob that is located at the timing switch outside, be arranged on the scroll spring 9 that drive knob rotates on the rotation axis, be enclosed within on the rotation axis cam be connected the buffer gear cold group 8 that is connected with cam in the mechanical timing switch, ratchet 14, scroll spring 9 drive knob axles rotate, and band moving cam and 8 rotations of buffer gear cold group, power passes to ratchet 14 after slowing down by buffer gear cold group 8, be provided with the plectrum 15 that limits its motion on the ratchet 14, because the restriction of plectrum 15, ratchet 14 is done uniform rotation, move with uniform velocity thereby control whole gear train, play time action, cam will promote moving contact and move upward after arriving setting-up time, closed or the disconnection of control contact switch regularly is switched on or switched off according to the default time with the control timing circuit.
The knob 2 31 of rotary machine formula timing switch 22 makes cam 27 with moving contact 2 12 jack-up, and moving contact 2 12 separates with fixed contact 2 13, and circuit disconnects and the beginning countdown; The knob 1 of rotary machine formula timing switch 1 again, make cam 1 with moving contact one 11 jack-up, moving contact 1 contacts with fixed contact 1, circuit is connected and the beginning countdown, the countdown time that mechanical timing switch 22 is set is shorter than the countdown time of mechanical timing switch 1, just can allow circuit connect after the countdown concluded at mechanical timing switch 22, disconnect after the countdown concluded at mechanical timing switch 1, namely show as the circuit control of a time period, realize finishing repeatedly the function of control command.
Above-described mechanical type autotimer of many times, can between two electrodes, connect three, four or more switch, each switch connects the mechanical timing switch of its closure of control, disconnection, by the countdown time of each mechanical timing switch is set, can control circuit in disconnection or the closure of different time sections, finish repeatedly control command, once set and can make circuit in multi-period energising or disconnection, determine according to actual needs the quantity of tandem tap, practical.
The utility model is connected in the loop of electrical appliance, the at times energising of control electrical appliance circuit, the timing controlled electrical appliance is opened or is closed, and also can with receiving in the electrical appliance loop after the parallel connection of a plurality of mechanical type autotimer of many times, also can realize the control to a plurality of time periods of electrical appliance.
Mechanical type autotimer of many times described in the utility model, by tandem tap between two electrodes, switch closure, the disconnection of connecting with electrode by mechanical timing switch control just can realize the function that multiple instruction is controlled, simple in structure, practical, produce easy to assemblyly, and cheap suitable large-scale popularization is used.
