Moreover, the locking time of the electromagnet is short, and the adsorption between the armature and the magnet is compact, which reduces the possibility of being unlocked by technology, and can also play a certain blocking role in violent disassembly.

Further, a return spring is provided between the locking post and the electromagnet, and when the electromagnet is powered off, the return spring drives the locking post to separate from the armature.

Due to the adoption of the above technical scheme, the return spring drives the limit plate to automatically return, which improves the convenience and applicability, and makes its use more customary.

Further, a self-locking spring is also included, and the self-locking spring connects the active rod with the side of the lock box close to the mortise lock.

Due to the adoption of the above technical solution, the self-locking spring can be set to a tensioned state or a normal state in the locked state, and then can achieve a certain spring rebound (self-locking) effect in the locked or unlocked state, further improving Safety performance of the utility model.

Further, the electromagnet communicates with the processor and the electronic combination lock sequentially, and the processor receives the input signal of the electronic combination lock and judges whether to turn on or off the electromagnet circuit.

Further, an alarm is also included, and the alarm is arranged in the lock box and communicated with the processor.

Due to the adoption of the above technical scheme, the overall intelligence, convenience and safety are improved by arranging the electronic password lock, the processor and the alarm.

In summary, due to the adoption of the above-mentioned technical means, the beneficial effects of the utility model are:

1. The structure is simple, the method is reliable, and the connection mechanism is stable and rigid.

2. The unlocking structure is simple, with fewer parts, and the lock can be unlocked with one action, which saves manpower.

3. The addition of electronic combination locks, etc., effectively improves the degree of intelligence and convenience.

4. Auxiliary control devices such as electromagnets are added, which have better locking and combining performance and higher reliability, further improving convenience.

detailed description

In order to further understand the utility model content, features and effects of the utility model, the following examples are exemplified, and the structure of the utility model is described in detail in conjunction with accompanying drawings 1 to 2 .

Embodiment 1: As shown in Figures 1 to 2, a self-locking electromagnetic lock for an electromagnetic shielding cabinet includes a lock box, and the inner cavity of the lock box is provided with an active rod 2 and a mortise lock 1, and the mortise lock 1 is set on one side of the lock box;

One end of the active rod 2 is connected to the lower part of the mortise lock 1, and the active rod 2 can drive the mortise lock 1 to move horizontally and retract into the lock box; the active rod 2 is connected with a self-locking spring 3, and the self-locking spring 3 The lock spring 3 connects the active rod 2 to the side of the lock box close to the mortise lock 1;

It also includes a stop rod 8, the stop rod 8 is arranged on the upper part of the lock box inner cavity and can move in the horizontal direction, the large end of the stop rod 8 is against the top of the mortise lock 1, and the horizontal The amount of movement is controlled by the stop rod 8; the small end of the stop rod 8 is also connected to the locking column 7 and the electromagnet 101, and the locking column 7 is connected to the armature end of the electromagnet 101; the locking column 7 and the electromagnet 101 are connected to each other; A return spring 102 is arranged between the electromagnets 101 .

In the locked state, the electromagnet 101 is powered off, and now the locking column is against the small end of the stop rod 8 and limits its horizontal movement;

When needing to unblank, electromagnet 101 energizes, and now electromagnet 101 and locking post 7 suck up and down, and stop bar 8 small end limits disappear, and stop bar 8 can freely move along the horizontal direction.

A preferred solution is that, in the above technical solution, the middle part of the stop rod 8 is also slidably connected with a driven rod 9, and the upper part of the driven rod 9 is connected with a lock cylinder 10, and the horizontal movement of the stop rod 8 drives The follower lever 9 stretches out and retracts into the lock box along the vertical direction.

A preferred solution is to connect the electromagnet 101 to the processor 5 and the electronic combination lock 4 in sequence, and the processor 5 receives the input signal of the electronic combination lock 4 and judges whether to turn on or off the circuit of the electromagnet 101; Including an alarm 6 arranged in the lock box and communicatively connected with the processor 5;

Under this setting, the state of unlocking and locking is as follows:

The unlocking operation is: when the correct code is input in the electronic combination lock 4, the processor 5 receives the input signal of the electronic combination lock 4 as a signal to connect the electromagnet 101 circuit.
