Description

Switch locking device

The utility model belongs to a kind of switch locking device, but particularly a kind of switch locking device that is used for operating equipments such as latch switch and disconnecting link.

The coding of latch switch is locked at present, and domestic generally have lock type electronic code lock, intelligent electronic coding lock etc. several.Though the locking principle difference, closedown mode is identical, all is the DC power supply by secondary circuit wiring lock operation switch.Therefore, all require control panel to have a power failure when Installation and Debugging, this transforms for the above electric substation of 220V (station) that is moving and makes troubles, and simultaneously general operation personnel are unwilling to change the original control panel mode of connection and retrain.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a place to break away from the secondary circuit wiring, does not need control panel to have a power failure during Installation and Debugging and also can carry out fool proof switch locking device by computer key.

The utility model is achieved in that it has a top that the box body of a doorframe is arranged, the door that has pintle hook lock is installed on the doorframe of box body, a pilot hole is arranged at the rear portion of box body, open hole and identifying hole, lock shaft is housed in open hole, chip and magnetic post are housed in identifying hole, bottom suit back-moving spring and the top dead bolt corresponding with pintle hook lock are housed in box body, on lock shaft, be connected with disk, be connected with connecting rod and lever between said disk and the dead bolt, constitute four-bar linkage, be fitted with the top at the middle part of box body and be connected with jacking block, the bottom is the push rod on inclined-plane, in the hole that the magnetic post is housed, be fitted with status block, the chassis of status block have a skewed slot and with the pressing mutually of push rod bottom surface, between the chassis of status block and box body, also be placed with back-moving spring.

Advantage of the present utility model is: it is to be used for the mechanical box of latch switch operation, opens door by computer key or skeleton key, therefore, breaks away from the secondary circuit wiring, does not need control panel to have a power failure when Installation and Debugging; Easy for installation, by installing hole with switch cover in this switch locking device; Have the anti-misoperation function, the computer key by anti-misoperation locking device carries out switching manipulation through decoder sense switch " branch ", " closing " state.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in drawings, it has a top that the box body 1 of a doorframe 1A is arranged, on the doorframe 1A of box body 1, pass through door-hinge 19, torsion spring 20 and axle 21 are equipped with the door 22 that has (being injected into one with door) pintle hook lock 23, a pilot hole 30 is arranged at the rear portion of box body 1, open hole 25 and identifying hole 26, lock shaft 24 is housed in open hole 25, chip 27 and magnetic post 28 are housed in identifying hole 26, the dividing plate 1B that passes box body 1 in bottom suit back-moving spring 10 and top and the dead bolt 17 corresponding with pintle hook lock 23 are equipped with in the left side in box body 1, dead bolt 17 is spacing by the block 18 that is bonded on the doorframe 1A, on lock shaft 24, be connected with disk 11 by nut 12, between dead bolt 17 and disk 11, pass through axle 16,7,9 and jump ring be connected with lever 13 and connecting rod 8, the middle part of said lever 13 is fixed on the box body 1 by axle 15 and nut 14, and above-mentioned parts constitute four-bar linkage.On the dividing plate 1B of box body 1, also has a through hole, in this through hole, be fitted with the top and be connected with jacking block 2, the bottom is the push rod 3 of inclined-plane 3A, said push rod 3 is spacing by slideway 6, in box body 1, be placed with status block 4 with push rod 3 correspondence positions, the chassis of said status block 4 have a skewed slot 4A and with push rod 3 bottom surface 3A pressings mutually, between the chassis of status block 4 and box body 1, be placed with back-moving spring 5, an edge bar 4B is arranged on the push rod of said status block 4, said edge bar 4B is inserted in the box body 1 in the through hole 29 corresponding with magnetic post 28, and its with magnetic post 28 between between be connected by magnetic force.

When real work, key is inserted in the open hole 25, dextrorotation turn 90 degrees, disk 11 is rotated counterclockwise 90 degree, promotes lever 13 by connecting rod 8 and rotates counterclockwise around axle 15, passes through lever principle, driving dead bolt 17 moves down, discharge door 22, door 22 is opened under the effect of torsion spring 20, can carry out on-the-spot switching manipulation.

When (switch is vertical), jacking block 2 and push rod 3 pressurizeds move down when on-the-spot switch is in ' closing ' state, promote status block 4 and drive magnetic post 28 to move forward, and can detect switch at " closing " state by computer key; When on-the-spot switch is in " branch " state (being switch level), because jacking block 2 is released, spring 5 promotes status block 4 and drives magnetic post 28 to move backward, is subjected to the promotion of status block 4, push rod 3 and jacking block 2 move up simultaneously, can detect switch at " branch " state by computer key.

In sum, by shutter door 22, can control operation to on-the-spot switch; By pressing or release jacking block 2, the state of identification switch automatically.
