Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides an intelligent lock for a cabinet door, including a housing 1, a locking block 2 rotatably disposed in the housing 1, an electromagnet assembly 3 disposed in the housing 1, a movable assembly 4 rotatably disposed in the housing 1 and having one end connected to an end of the electromagnet assembly 3, and a magnetic inductive switch 5 disposed in the housing 1 and located at a side of the locking block 2, wherein the locking block 2 has a locking hook 21 and a hook arm 22, and the other end of the movable assembly 4 has a hook position 41 for hooking an end of the hook arm 22; a magnet 6 corresponding to the magnetic induction switch 5 is provided on the side of the hook arm 22 of the locking block 2.

Combine together by magnetic induction switch 5 and magnet 6, only in the complete abundant locking in the hook position 41 of movable component 4 of hook arm 22 of locking piece 2, the magnetic induction switch 5 just can sense the magnetic signal of magnet 6 on the hook arm 22 side, magnetic induction switch 5 just can switch on, the signal that the accurate output cabinet door has locked, when the cabinet door is totally fully locked in place, magnetic induction switch 5 just can send the signal of locking, the phenomenon of erroneous judgement can not appear from this, the phenomenon that the cabinet door does not lock can not appear yet, the safety of article in the cabinet has been guaranteed.

In this embodiment, the distance between the magnet 6 and the magnetic inductive switch 5 is generally adjusted by the strength of the magnetism of the magnet 6, and the stronger the magnetism of the magnet 6, the farther the distance therebetween, and conversely, the weaker the magnetism of the magnet 6, the closer the distance therebetween. In the present embodiment, it is preferable that the distance between the magnet 6 and the magnetic inductive switch 5 is not greater than 0.15mm, that is, when the distance between the magnet 6 and the magnetic inductive switch 5 is equal to 0.15mm, the distance is the maximum distance that the magnetic inductive switch 5 can sense; when the distance between the magnet 6 and the magnetic induction switch 5 is less than 0.15mm, the magnetic induction switch 5 can induce the magnetic signal of the magnet 6, and the sensitivity and the reliability of the induction process are high.

In this embodiment, the magnetic inductive switch 5 is a reed switch or a PNP transistor. Meanwhile, the magnet 6 is a permanent magnet. In a specific product, the magnetic induction switch 5 and the electromagnet assembly 3 can be connected to an external electronic circuit, and can also be directly connected into a computer management system. The working principle of the magnetic induction switch 5 is as follows: when the magnetic induction switch 5 does not induce the magnetic signal, the circuit is disconnected, and the magnetic induction switch 5 is not conducted; when the magnetic induction switch 5 induces a magnetic signal, the circuit is switched on, the magnetic induction switch 5 is switched on, and a signal that the cabinet door is locked is output.

In the present embodiment, specifically, as shown in fig. 1 and fig. 2, the electromagnet assembly 3 includes an electromagnet 31 and a sliding rod 32 telescopically inserted into the electromagnet 31, a return spring 33 is sleeved on an outer end of the electromagnet 31 at the periphery of the sliding rod 32, and an outer end of the sliding rod 32 is connected to an end of the movable assembly 4.

Specifically, the movable assembly 4 includes a movable block 42, and a screw 43 connected to an end of the movable block 42 and connected to an outer end of the sliding rod 32; the hook position 41 is a locking hook disposed at an end of the movable block 42 and used for hooking an end of the hook arm 22. Meanwhile, the outer end of the slide rod 32 has a through hole 321 for the screw 43 to pass through.

In this embodiment, the locking block 2 is provided with a first sleeve hole, a first fixing column 11 inserted into the first sleeve hole is fixed in the housing 1, and the locking block 2 is rotatably connected to the first fixing column 11; a first hook spring 7 is sleeved outside the first fixing column 11, and the end of the first hook spring 7 is hooked on the hook arm 22. Meanwhile, a second sleeve hole is formed in the movable block 42, a second fixed column 12 inserted into the second sleeve hole is fixed in the housing 1, and the movable block 42 is rotatably connected to the second fixed column 12; a second hook spring 8 is sleeved outside the second fixing column 12, and the end of the second hook spring 8 is hooked on the hook arm 22. By combining the first hook spring 7 and the second hook spring 8 on the hook arm 22, the first hook spring 7 and the second hook spring 8 have a certain expansion range, so that the locking block 2 rotates in a certain range, and the locking block 2 is prevented from rotating greatly and losing the locking effect.

The working principle of the embodiment is as follows:

when locking is needed, the lock catch 10 is pushed into the jack 20 on the side edge of the shell 1, the lock catch 10 pushes the lock hook 21 on the locking block 2, and the locking block 2 rotates along with the rotation until the lock catch 10 is hooked into the lock hook 21; at the same time, the hook arm 22 enters the hook position 41 of the movable block 42, so that the locking hook hooks the hook arm 22, thereby locking the latch 10, as shown in fig. 2 and 4, and realizing the locking function of the door cabinet. When the end of the hook arm 22 of the locking block 2 is hooked into the locking hook, the magnetic induction switch 5 induces the magnetic signal of the magnet 6 on the side edge of the hook arm 22, so that the magnetic induction switch 5 is switched on, and the signal that the cabinet door is locked is accurately output.

When the lock needs to be unlocked, the electromagnet 31 is energized, the iron core inside the electromagnet 31 generates an attraction force on the sliding rod 32, so that the sliding rod 32 moves towards the iron core, the screw 43 is pulled to swing towards the electromagnet 31, and the return spring 33 is compressed, as can be seen from the lever principle, the locking hook of the movable block 42 swings upwards (away from the locking block 2) to separate the locking hook from the hook arm 22, so that the locking force applied to the hook arm 22 is released, and the locking block 2 rotates to separate the lock catch 10 from the lock hook 21, so that the lock catch can be pulled out, and the unlocking function is realized, as shown in fig. 1. Then, the movable block 42 and the slide bar 32 are restored by the elastic restoring force of the restoring spring 33.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
