In order to overcome the defects in the prior art, the invention provides the single three-lock-hole electric control lock which adopts one electromagnet to control three groups of lock cylinders and can lock and unlock three lock catches simultaneously.

The technical scheme adopted by the invention for solving the technical problems is as follows: a single three-lock-hole electric control lock comprises a lock shell, a lock cover, an electromagnet, a lock tongue, a lock hook and a torsion spring, wherein a shaft rod used for fixing the lock tongue and the lock hook is arranged in the lock shell, lock hole grooves are formed in the wall of the lock shell and the lock cover, a manual unlocking hole is formed in the wall of the lock shell, the lock tongue corresponds to the lock hole grooves in the wall of the lock shell, and the electromagnet controls the lock hook through a link mechanism.

In the single three-lock-hole electric control lock, the electromagnet is a non-through type push-pull electromagnet, and a double-faced flat groove is formed in the end part, close to the armature, of the electromagnet and used for pulling the lock hook.

The single three-lockhole electric control lock comprises three pairs of lock tongues and lock hooks, wherein the three lock tongues are U-shaped open lock tongues with shaft holes, and the shaft holes are positioned at the bottom of the U-shaped lock tongues; the hook ends of the three lock hooks are all platforms with bevel edges at the front edges, and the middle parts of the three lock hooks are provided with shaft holes; the second lock hook is provided with a long arm connecting rod outside the lock hook and connected with an armature of the electromagnet; the lock tongue, the lock hook and the torsion spring are respectively sleeved on a shaft lever in the lock shell; the lock tongue and the lock hook can rotate around the shaft lever. The end of the long arm connecting rod of the second lock hook and the handle end of the first lock hook are connected with the armature of the electromagnet, and the handle end of the second lock hook and the handle end of the third lock hook are arranged in parallel and oppositely.

Optionally, the electromagnet can also adopt a titanium wire, and the first locking hook and the second locking hook are pulled by utilizing the characteristic that the titanium wire is heated to shrink, so that the unlocking purpose is achieved.

The single-body three-lock-hole electric control lock has the advantages that the single-body three-lock-hole electric control lock can realize that one lock simultaneously locks and unlocks three lock catches, has small volume, light weight and low power consumption, and can meet the application that the size, the weight and the power consumption have higher requirements, such as the quick detachment of an animal muzzle and the like.
