Technical Field

The invention belongs to the technical field of electronic locks, and particularly relates to an electronic lock.

Background

At present, the known electronic locks for security equipment such as cabinets and the like use electronic locks with different structures by considering factors such as box materials, sizes, purposes and the like. Under normal conditions, the cabinet user passes through the correct signal of telecommunication of external equipment input, makes the control circuit in the box provide electric power for the tool to lock mechanism, and after the tool to lock obtained electric power, the realization electronization was opened, but actual conditions are: the existing cabinet lockset has the defects of complex structure, high manufacturing cost, simple structure and poor safety, and in addition, the metal cabinet cannot be normally opened due to the fact that a mechanical structure or a control circuit of the lockset breaks down.

The invention belongs to the technical field of electronic locks, and particularly relates to an electronic lock which comprises a shell, a first rotating shaft, a second rotating shaft, a first torsion spring, a second torsion spring and a third torsion spring, wherein a bolt is arranged, one end of the bolt extends out from the upper opening end of the shell, and the other end of the bolt is arranged in the shell, and the electronic lock is characterized in that: still be equipped with the lock block in the casing, lock block and the mutual swing joint of spring bolt still are equipped with the motor in the casing, and the motor rotates through its epaxial dog and controls the switching, simple structure, with low costs production.

To this end, we propose an electronic lock to solve the above problems.

Disclosure of Invention

The invention aims to solve the problems and provides an electronic lock which is safe, reliable and good in stability.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an electronic lock, includes casing, first pivot, second pivot, first torsional spring, second torsional spring, third torsional spring, wherein is equipped with the spring bolt, the one end of spring bolt stretches out from the open end of casing, and one end is in the casing in addition, still be equipped with the locking piece in the casing, the locking piece with the mutual swing joint of spring bolt, still be equipped with the motor in the casing, the motor rotates through its epaxial dog and controls the switching.

In the electronic lock, the lock tongue and the lock block are respectively arranged on the first rotating shaft and the second rotating shaft in the shell.

In the electronic lock, the lock tongue, the locking block and the stop block on the motor shaft are respectively acted by the first torsion spring, the second torsion spring and the third torsion spring.

In foretell electronic lock, there is the bump on the spring bolt, the spring bolt is through its bump and locking piece swing joint, the end of locking piece has the latch hook, when the spring bolt rotates the bump is pulled the locking piece and is rotated, the terminal latch hook of locking piece hooks the spring bolt and forms mutual locking.

In the electronic lock, when the lock hook hooks the lock tongue, the stop block is limited by the action of the torsion spring to move the locking block.

In the electronic lock, the stop block is also provided with stop block convex points which are matched with the stop block to limit the stop block to be opened in a rotating mode.

Compared with the prior art, the electronic lock has the advantages that:

the spring bolt replies the normal position in-process under exogenic action such as torsional spring, bump and locking piece recess limit sliding contact on the spring bolt to promote the locking piece to rotate to the direction that resets, the locking piece in-process that resets, the spring bolt is hooked again in the latch hook removal, and the epaxial dog of motor rotates spacingly under the torsional spring effect, and restriction locking piece can not the direction rotate, realizes the locking. The advantages are that: simple structure, low cost and production, safety, reliability and stable performance.
