Abstract

The utility model relates to a lock, more specifically a double-insurance electronic lock controlled by an electronic circuit. The utility model adopts an electronic control circuit, after the electronic circuit is switched on, a key of the utility model can work; when the electronic circuit is not switched on, only the key can not be used for opening the utility model, and a double-insurance function is performed. The utility model is provided with two external joints which are connected with an external control circuit which can be controlled by codes or a card type controller. The utility model has the advantages of convenient operation and high safety.

Description

A kind of electronic lock

The utility model relates to place lock, a kind of specifically electronic lock that can use the double insurance of electronic circuit control.

Lock is the requisite commodity of telecommuting, and the patent of lock also has a variety of, and along with the raising of technical level and the raising of safety requirements, electronic lock also appears at the field of lock.Existing multiple at present electronic lock occurs, as the patent No. is that 93233083 name is called " but double lock tongue theftproof lock of electronic telecontrol ", it is a kind of by the dead bolt box, lock body, main dead bolt, secondary dead bolt, interlock lock frame, safeguard, shift fork, energy-storaging spring, but the double lock tongue theftproof lock of the electronic telecontrol that gib and electric control part are grouped into, wherein device has the circle wheel on the dead bolt box, and have a hole of matching with main dead bolt, secondary dead bolt is corresponding with the circle wheel, and be positioned between lock body and the support member, on it suit be fixed with safeguard interlock lock frame, this can be along secondary dead bolt and spacer pin displacement, main lock bolt sleeve is contained between lock body and the interlock lock frame, its bar is provided with spring, its rear lower has and the safeguard corresponding hole of platform of insuring, shift fork one end is located on the lock body, and a breach is arranged on it, and this breach can overlap and hook interlock lock frame, its other end can overlap mutually and locate with gib, and gib can be by electromagnet or mechanical lock control.The shortcoming of this lock is that key is in a single day stolen, and then safety just can't ensure.

Utility model can be achieved through the following technical solutions:

A kind of electric lock, by housing parts, tapered end part and the frame for movement composition that the motion of tapered end part is carried out transmission, wherein housing parts is made up of lock housing (1) and base plate (2), tapered end partly is by tapered end (3), snap (16), dead bolt (4) and dead bolt spring (17) are formed, dead bolt spring (17) withstands in dead bolt (4) below can not get back to lock housing (1) inside when dead bolt (4) makes it in operate as normal, frame for movement is by slide block (5,6), brake block (7), and partial fixing device composition, it is characterized in that: it also comprises the electronic control circuit of control lock head part work.

In technique scheme, described electronic control circuit by electromagnetic coil (12), power supply (13), be used for the electromagnetic pole (14) of direct control lock head part mechanical movement and the spring (15) that is used to reset is formed, electromagnetic coil (12) has two joints, is used for joining with outside control circuit.

Because the utility model has adopted electronic control circuit, after electronic circuit was connected, the utility model key just can work, and when electronic circuit is obstructed, only can not open the utility model with key, so just can play double shield.The utility model has two external lugs, is used for linking to each other with external control circuit, and external control circuit can be controlled with password or cassette controller.Very easy to use, safe and reliable.

Below in conjunction with accompanying drawing the utility model is done further embodiment explanation:

Figure 1 shows that the utility model internal construction schematic diagram;

Figure 2 shows that the utility model surface structure schematic diagram;

Figure 3 shows that the utility model side direction schematic appearance;

As Fig. 1,2, shown in 3, the utility model is by housing parts, tapered end part and the frame for movement that transmission is carried out in the motion of tapered end part, electronic control circuit is formed, wherein housing parts is by tapered end 3, snap 16, dead bolt 4 and dead bolt spring 17 are formed, dead bolt spring 17 can not be got back to lock housing 1 inside when dead bolt 4 makes it in operate as normal withstanding below the dead bolt 4, frame for movement is by sliding shoe 5,6, brake block 7 and partial fixing device are formed, the electronic control circuit of control lock head part work is by electromagnetic coil 12, power supply 13, the electromagnetic pole 14 that is used for the mechanical movement of direct control lock head part, the spring 15 that is used to reset is formed, whether electromagnetic coil 12 effects are brake block 7 adhesives, be used for control lock and can be opened by key.

In use, general outside all connects a controller, as Crypto Control Unit or card controller.After peripheral control unit was connected, promptly after password or card test correctly, it is inner that signal is sent into lock from two external lugs of electromagnetic coil 12, and electromagnetic coil conducting at this moment picks up brake block 7, and at this moment electronic lock just can have been opened with key.When not conducting of peripheral control unit, electromagnetic coil 12 no currents pass through, so magnetic coil 12 is inoperative, then spring 15 effects reset brake block 7 down, make brake block 7 that sliding shoe 6 is blocked, and at this moment also electronic lock can't have been opened with key.

Claims

1. electronic lock, by housing parts, tapered end part and the frame for movement composition that the motion of tapered end part is carried out transmission, wherein housing parts is made up of lock housing (1) and base plate (2), tapered end partly is by tapered end (3), snap (16), dead bolt (4) and dead bolt spring (17) are formed, dead bolt spring (17) withstands in dead bolt (4) below can not get back to lock housing (1) inside when dead bolt (4) makes it in operate as normal, frame for movement is by slide block (5,6), brake block (7), and partial fixing device composition, it is characterized in that: it also comprises the electronic control circuit of control lock head part work.

2. a kind of electronic lock according to claim 1, it is characterized in that: described electronic control circuit by electromagnetic coil (12), power supply (13), be used for the electromagnetic pole (14) of direct control lock head part mechanical movement and the spring (15) that is used to reset is formed, electromagnetic coil (12) has two joints to be used for joining with outside control circuit.
