Abstract
The utility model relates to a program control lock for controlling power transfer programs, particularly an acoustic-optic alarm magnetic control switch lock. The utility model comprises an outer plastic shell, a toggle switch, an electric magnet, a rotary ring driven by a turn button, and an acoustic-optic alarm circuit. The utility model has the characteristics of easy operation, safety, etc., is used for program switch and control in power transmission, can reduce operation accidents due to mistake switching, and can ensure the safe operation of electric network.
Description
The utility model relates to a kind of electromagnetic switch lock, carries the sound and light alarm magnetic switch lock of department to the control of transmission of electricity auto-programming switch in particular for electric power.
At present, electric power carries the forced service operating personnel of department according to promptly fixed operation sequence, and transmission facility is carried out operation, generally adopts common spring lock to lock the misoperation that prevents electrical equipment as grammed switch, guarantees the safe operation of electrical network.But it is more bothersome that common spring lock has use, can not link with appliance switch, and the switch operation shows the unclear deficiency that waits.
The purpose of this utility model provide a kind of simple to operate, switch is rapid, has the sound and light alarm magnetic switch lock that sound and light alarm shows.
The purpose of this utility model realizes in the following manner.
Mould installation electromagnet and toggle switch and sound light alarming circuit in the system shell one, the knob that one belt length axle is arranged, knob is in shell foreign minister axle is beaten into shell, fix a change that is processed with groove and location hole on major axis, the top is equipped with toggle switch near the position of groove, and electromagnet is equipped with by the position of location hole in the below, as want turning knob to drive toggle switch, at first will make electromagnetic actuation, switch finishes electromagnet is discharged, and the alignment pin at electromagnet top pins change.The switch of sound and light alarm and electromagnet is by the last switch lock control in the program, the toggle switch of this switch is controlled the electromagnet and the sound and light alarm of next program, analogize therewith, lock of every startup all makes next lock report to the police, follow procedure has started, and transmission facility could move to avoid opening by mistake closing and cause the accident.
Figure of description (1) is a plane structure chart of the present utility model;
Figure of description (2) is a sectional view of the present utility model;
Figure of description (3) is a faceplate view of the present utility model.
The utility model will be further described with reference to Figure of description.
The panel (2) that the knob (1) of a band major axis (3) passes major axis (3) and is fixed on the shell (5) injects in the shell (5), there is the change (4) of a trough of belt and locating hole to be fixed on the major axis (3), in the top of change (4) toggle switch (6) is arranged, there is an electromagnet (8) below, both all are fixed on the shell (5), the handle of toggle switch (6) is positioned at the groove of change (4), the alignment pin at iron core top is positioned at the locating hole of change (4) in the electromagnet (8), and change (4) is turned to clockwise 90 ° and also had a locating hole
In order to meet emergencies, the utility model also is provided with emergency release device (7), and its button is installed in shell (5) top, and the button below has on the iron core of a link rob in electromagnet. Run into emergency, pressing button, to make alignment pin withdraw from locating hole be rotatable knob. Integrated alarm circuit plate (12) and piezo-electric ceramic sounding element (9) and light emitting diode (10) also are housed in shell (5), the pass of electromagnet (8) and sound light alarming circuit is logical by the upper program magnetic switch control in the program, and this lock is controlled again magnet and the sound light alarming circuit in next program.
The louver that hole of light emitting diode and sounding component are arranged in the positive below of shell (5) dress panel (2) and knob (1).
Embodiment:
Magnetic switch interlocking of the present utility model is to the switching signal of a last program, sound and light alarm is sent in the work of electromagnetic actuation sound light alarming circuit, rotatable knob control this moment power equipment switch is also connected the magnetic control lock of next program, at this moment, the toggle switch of this lock is closed the warning circuit of this lock, simultaneously, connect the electromagnet and the sound light alarming circuit of the magnetic control lock of next program, carry until electrical network by that analogy and open or close.
Need this magnetic switch of switch lock as emergency, the button that can press the emergency release device makes in the location hole of alignment pin from change of electromagnet and withdraws from, and can unblank or shut.
Except that the technical characterictic described in the specification, be known technology.
Claims (5)
1, a kind of sound and light alarm magnetic switch lock comprises shell, electromagnet, toggle switch, change, knob, emergency release device and sound light alarming circuit etc., it is characterized in that: change is installed on the rotation axis, and electromagnet is installed in the change below.Toggle switch is installed in the change top.
2, switch lock according to claim 1 is characterized in that the handle that is processed with groove and location hole toggle switch in the change beats in groove, and the iron core of electromagnet is beaten in the location hole.
