Description

A male plug for a lock based on an electromagnet

Technical Field

The invention belongs to the field of locks, and in particular relates to a male plug of a lock based on an electromagnet.

Background Art

Nowadays, many locks require the function of connecting to a power source while locking. Among them, a lock with opposing lock tongues is a relatively ideal lock that can realize the power connection function. Its two lock tongues are claw-hook shaped and are relatively arranged on the lock shell. The two hook-shaped lock tongues are driven to move toward or relative to each other through a driving device and a transmission device at the same time, so that the power source can be connected and disconnected while the lock is locked and unlocked. However, most of the existing locks with opposing lock tongues have the disadvantages of being large in size, easy to wear, asynchronous movement of the lock tongue, and unable to lock automatically, which leads to problems such as short service life, poor usability, weak applicability, and unstable power connection.

When in the initial state, the electromagnet part is not energized, and the armature part is separated from the electromagnet part under the elastic force of the spring, so that the two lock tongues extend out of the left and right sides of the lock respectively;

When locking is required, the male plug of the lock is moved close to the female plug assembly under the action of external force. After the female plug electrode connector on the female plug assembly touches the arc surface of the two lock tongues of the male plug of the lock, the two lock tongues are pushed to move toward the center from the left and right sides, so that the two lock tongues are automatically retracted into the lock. When the male plug of the lock is completely plugged into the female plug assembly, the armature part is separated from the electromagnet part again under the elastic force of the spring, so that the two lock tongues are respectively extended out of the left and right sides of the lock, thereby realizing automatic locking, and making the electrode connectors of the two lock tongues fully contact with the electrode connector on the female plug assembly, so as to realize the conduction between the male plug assembly and the female plug assembly;

When unlocking is required, the electromagnet part is energized, and the armature part fits with the electromagnet part under the action of the magnetic force of the electromagnet part, so that the two lock tongues are automatically retracted into the lock, thereby realizing unlocking, and the electrode connectors of the two lock tongues are also separated from the electrode connector of the female plug component at the same time, realizing the disconnection of the male plug component and the female plug component; and after unlocking, the electromagnet part is powered off again, and the armature part is separated from the electromagnet part under the elastic force of the spring, so that the two lock tongues are respectively extended out of the left and right sides of the lock, and restored to the initial state.

The beneficial effects of the present invention are as follows:

The present invention connects two lock tongues to the electromagnet and the armature respectively, and connects a spring between the electromagnet and the armature, utilizes the magnetic property of the electromagnet after being energized and the elastic force of the spring, realizes the rapid movement of the two opposing lock tongues toward and in the opposite direction, makes the two lock tongues of the male plug of the lock have excellent synchronization when unlocking, and improves the stability of the power connection between the male plug assembly and the female plug assembly, and improves the use effect of the existing similar locks.

The present invention arranges an elastic member between the electromagnet and the iron block, so that the iron block can be separated from the electromagnet when the electromagnet is not energized, and an arc surface is arranged on the lock tongue, so that the lock tongue can be guided to move inward when it contacts the female plug and shrink inward accordingly, and when the lock tongue is inserted into the female plug, it can extend outward under the elastic force of the elastic member, thereby realizing automatic locking of the lock, and also making the power connection more stable when the male plug and the female plug assembly of the lock are locked.

The present invention provides pin mounting seat sliding grooves on the front and rear retaining edges of the bottom cover, respectively, which, on the one hand, provide accommodation space for the pin mounting seat on the lock tongue, and on the other hand, can prevent the lock tongue from shaking in the up-down direction and the front-back direction when moving, further improving the stability of the lock tongue when moving left and right. At the same time, the present invention also provides a pin mounting seat sliding limit block on the pin mounting seat sliding groove, which can prevent the situation where the lock tongue on one side only moves toward the lock tongue on the other side, further improving the synchronization of the lock tongues in the opposite movements.
