The lockset 2 comprises a shell 21, a lock bolt 22 and a locking module, wherein a sliding groove 211 is arranged in the shell 21, the lock bolt 22 is arranged in the sliding groove 211 in a long-strip-shaped sliding manner, one end of the lock bolt 22 extends out of the shell 21, a first elastic piece 24 is arranged between the other end of the lock bolt 22 and the shell 21, and a locking groove 25 is formed in one side of the lock bolt 22 along the length direction of the lock bolt;
the locking module comprises a mounting groove 212 arranged in the shell 21, a locking lug 27 arranged in the mounting groove 212 and an electromagnet 28, one end of the locking lug 27 is matched with the locking groove 25 and can extend into the locking groove 25 to form limit fit with the lock bolt 22, the electromagnet 28 is fixed at the position, far away from the locking lug 27, of the mounting groove 212, and a second elastic element 29 is arranged between the electromagnet 28 and the locking lug 27;
the shell 21 is provided with an electric socket 213, the electric socket is electrically connected with the electromagnet 28, the key 3 is provided with an electric plug 31 matched with the electric socket 213, the key 3 is internally provided with a mobile power supply, and when the electric plug 31 is inserted into the electric socket 213, the electromagnet 28 conducts electricity and attracts the locking lug 27 to exit the locking groove 25;
the switch blade 1 is provided with a plurality of insertion holes 11 adapted to the latches 22, and in the open and closed state of the switch blade 1, one insertion hole 11 is aligned with each latch 22.
In the specific implementation, a worker holds the key 3, and inserts the power plug 31 of the key 3 into the power receiving slot 213 of the housing 21, at this time, the electromagnet 28 conducts electricity and attracts the locking protrusion 27 to exit from the locking slot 25, and meanwhile, the locking protrusion 27 compresses the second elastic member 29 in the moving process. The locking bolt 22 can then be withdrawn from the insertion opening 11 of the switch blade 1 by means of an external force, slid on the side of the housing 21 facing away from the switch blade 1 and compressed against the first spring element 24. The switch knife 1 is unlocked, the opening or closing state of the switch knife 1 is adjusted at the moment, after the switch knife 1 is adjusted in place, one insertion hole 11 in the switch knife 1 is aligned with the lock plunger 22, the lock plunger 22 is inserted into the insertion hole 11 under the pushing of the first elastic piece 24 to lock the switch knife 1 again, at the moment, a worker enables the key 3 to be separated from the power connection insertion slot 213, the electromagnet 28 is powered off, the magnetic force disappears, the locking lug 27 is inserted into the locking slot 25 again under the pushing of the second elastic piece 29, and the lock 2 is locked again. After the working of the staff is finished, the actions are repeated, and the switch knife 1 is reset.
The utility model discloses, because of the tool to lock setting is in one side of switch knife, the tool to lock can not have and drop and hang wrong possibility. Meanwhile, because the switch knife is in the opening and closing state and is respectively provided with the jack aligned with the lock bolt, no matter the switch knife is in the opening or closing state, the lockset can automatically lock the switch knife, the switch knife can be effectively prevented from being touched by mistake, and the personal safety of workers is guaranteed. And, through setting up portable power source inside the key, not only guaranteed the tool to lock and be difficult to open under the condition that does not have the key, solved the power supply problem of tool to lock moreover, need not set up a power for the tool to lock alone again, remove the problem of changing the power for the tool to lock from.
And the lock bolt is set to be in a mode that the lock bolt can only be withdrawn from the jack on the switch knife by means of external force, so that once the external force is lost, the lock bolt can automatically lock the switch knife, and the structure is reliable and durable. Through designing into the shutting module electro-magnet mode of inhaling for the power of electro-magnet is little, and is small because of the locking lug is less, and the heat that the electro-magnet of small volume produced is few, and the heat dissipation is fast, and difficult emergence is damaged, makes equipment more reliable.
The latch 22 is an elongated bar, and the cross section thereof may be any shape such as a rectangle, a circle, etc. The first elastic member 24 and the second elastic member 29 are both springs.
In an embodiment, a magnetic stripe 26 is disposed in the power connection slot 213, the magnetic stripe 26 carries an independent code thereon, and the key 3 further includes a sensing module, a control module and a wireless transmission module, wherein the sensing module is disposed at a position corresponding to the magnetic stripe 26 of the power connection plug 31, and is configured to read information on the magnetic stripe 26 and transmit the information to the control module. The control module is used for processing the transmitted information and sending the processed information to an external terminal processor independent of the key 3 through the wireless transmission module, the terminal processor confirms whether the code of the lock 2 is correct or not through information comparison, then sends a signal back to the control module, and the control module controls the switch of the mobile power supply according to the signal sent back by the terminal processor. Design like this, the tool to lock that can ensure that the staff and open is appointed tool to lock, avoids wrong other tool to lock of opening, and the staff's accessible presets the working order on terminal processor simultaneously, and the staff just can open each tool to lock in proper order according to the unblock order of regulation like this, handles each switch plug-in strip, and very big standard staff's operation avoids line system to break down, improves staff's security.
The control module comprises a receiving module used for receiving signals sent by the terminal processor. The terminal processor may be a computer.
In an embodiment, the key 3 is further provided with an indicator lamp 32, when the signal sent back by the terminal processor is an acknowledgement signal, the control module controls the mobile power supply to be turned on and simultaneously controls the indicator lamp 32 to be turned on, and the indicator lamp 32 emits light with the first color. When the signal sent back by the terminal processor is a negative signal, the control module controls the mobile power supply to be kept off at the moment, and controls the indicator lamp 32 to be turned on at the same time, so that the indicator lamp 32 emits light with the second color, or the indicator lamp 32 is turned off. By the design, the staff can clearly know whether the lock 2 is a corresponding lock through the indicator lamp 32, and the working efficiency is improved.
In an embodiment, a first strip-shaped groove 214 is formed in the top of the housing 21 at a position corresponding to the sliding slot 211 along the length direction of the sliding slot 211, a pushing block 23 facilitating manual pushing is disposed on the first strip-shaped groove 214, and the pushing block 23 is connected with the locking bolt 22 to drive the locking bolt 22 to slide in the sliding slot 211. By the design, the pushing block is moved by a worker with hands, so that the lock bolt can withdraw from the jack on the switch knife, and the operation is more convenient.
In an embodiment, a second strip-shaped groove 215 is opened on the top of the housing 21 at a position corresponding to the mounting groove 212 along the moving direction of the locking protrusion 27, a connecting column 271 is disposed in the second strip-shaped groove 215, one end of the connecting column 271 is connected with the locking protrusion 27, and the other end of the connecting column 271 does not exceed the top surface of the housing 21. By the design, when the locking module is damaged, a worker can drive the locking lug to remove the limitation on the lock bolt through the connecting column by a special tool, and the influence of the locking lug on the engineering progress is reduced.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
