Abstract

The utility model discloses an electrical switch device controlled by a cipher lock, which is suitable for the simultaneous opening or closing of a plurality of circuits of AC and DC with volt of 380 volts and below 380 volts. The utility model is characterized in that a moveable key is provided with additional teeth which pass through the bottom of a lock body. When the key matches with the cipher and is withdrew a certain length, an electric switch is driven to switch circuits connected by a plurality of contacts on or off. The structure is very simple when the ladderlike contacts are adopted. When the key is totally inserted into the lock body or withdrew a certain length, the switch can only be altered when the key matches with the cipher in the original state or the operating state. The utility model has the advantages of convenient installation and operation and easy manufacture, and all elements can be assembled in one casing.

Description

Electric switch for mechanical combination lock

The utility model belongs to a kind of appliance switch.The electric switch that particularly has mechanical code lock.

Do not find the electric switch of band mechanical code lock at present as yet.Though the similar coded lock of mechanical code lock that municipalization is included with the utility model does not have electric switch.Equally, existing electric switch does not combine with mechanical code lock yet.Thereby they do not have the function with coded lock control electric switch.

The utility model purpose provides a kind of device that mechanical code lock and electric switch are combined.Have only in the use and can stir energising or the outage that the electric switch button is realized array (1-10 group) circuit, otherwise electric switch can not be struck, thereby realize circuit security personnel requirement the symbol password.

The key that the purpose of this utility model is achieved in that mechanical code lock with stir or the toggle of electric switch connects.Stir or electric switch is furnished with array (1-10 group) and opens contact and closed contact switch toggle with switch movable contact and insulating trip assembling.Mechanical code lock ring-type digital disk is free to rotate, when joining the symbol password, and the breach alignment of digital disk, key can freely insert or transfer to lock body.Joining key with hand toggle switch toggle because of toggle one end this moment, so key is pulled out a segment length, and because of the toggle other end is joining the electric switch moving contact, so moving contact moves, becket inserts to open to contact between the contact sets circuit is connected on the contact.Insulating trip inserts the closed contact group and makes the circuit disconnection on the contact.At this moment the coded lock figure disc is recovered arbitrary position then switch be lockable.Then need again password stirred with hand then and start toggle and key is inserted lock body then switch movable contact is to moving in the other direction as changing on off state, becket and insulating trip leave out contact and closed contact and circuit is disconnected or connect.

When key is pulled out a segment length, contain key in the partial password dish and play lock having only, at this moment easily by the people with the trial and error method by cryptography.For preventing that this situation the utility model from being two teeth at additional on the key embodiment of plurality of teeth (1-4 tooth) of common coded lock, this moment is when key is pulled out two tine length, all still all contain key in the combination disk, thereby guarantee that coded lock all is difficult for being separated the sign indicating number of decoding under unlatching or closed condition, increased fail safe.So because of key lengthening lock body end also has keyhole, outside the extended lock body of key, whole device is loaded in the insulation shell, constitutes an independently switching device.

The utlity model has following advantage: 1, coded lock and electric switch are formed one and can be realized locking to electric switch.2, the coded lock key has additional teeth can prevent that coded lock from being broken a code with trial-and-error method under opening.3, the appliance switch part can be controlled the break-make of array circuit simultaneously.4, all being installed on interior safe and reliable being easy to of an insulation shell installs and uses.5, making simple material does not have specific (special) requirements, and cost is low.6, combination disk can require to increase or to reduce according to level of confidentiality, also changeable of numerical digit on the dish, but recompile when needing.When adopting following example structure, make simple.Below in conjunction with accompanying drawing this utility model is described further.

Accompanying drawing 1 is a routine structural representation of the present utility model

Accompanying drawing 2 is the A-A profile

Accompanying drawing 3 is the key figure that have additional teeth (2 tooth)

As accompanying drawing 1, this device comprises mechanical code lock (1), switch toggle (2), and portable key (3), electric switch moving contact (4), insulating barrier (6) is opened contact (5), and closed contact (7) and shell (8) constitute.Accompanying drawing 2 shows lock core column (21), packing ring (22), digital disk (23) combining structure.Digital disk is free to rotate, and when joining the symbol password, key (3) can be pulled outwardly interlock moving contact (4), and insulating barrier (6) inserts and opens contact (5), and closed contact (7) is switched on or switched off circuit.Rotate digital disk this moment and become digital arbitrarily combination, stay in the lock, key can be pushed original position so still need join the symbol password because of key still has enough teeth.Reliable operation simple in structure, good confidentiality.

All device is loaded in the housing (9), is convenient to install and use.

Claims

1, one by coded lock lock body (1), switch toggle (2), and portable key (3) moving contact (4), insulating trip (6) is opened contact (5), the mechanical code lock electric switchgear that closed contact (7) and shell (9) etc. are formed; It is characterized in that the key and the switch toggle (2) of coded lock, switch movable contact (4) insulating trip (6) connects together, only when coded lock is joined the symbol password, can make institute's control circuit power on/off by the toggle switch toggle.

2, the mechanical code lock electric switch of stipulating by claim 1, it is characterized in that all there is keyhole at coded lock lock body two ends, key (3) have additional key bit make coded lock open and blocking under all need join accord with password can mobile key, prevent that effectively coded lock from decoding with trial-and-error method.

3, the mechanical cipher by claim 1 regulation does not have electric switchgear, and it is characterized in that connecting the lock key other end by electric switch toggle one end, to connect the stepped contact of switching that electric switch moving contact (4) insulating trip (6) can control the array circuit simultaneously by plug be a special case structure.
