Description

A kind of drawout cubicle minitype electronic lock

Technical field

The present invention relates to a kind of small electronic lock, especially a kind of drawout cubicle minitype electronic lock.

Background technique

Lockset is the tool that the mankind are used to protect itself property safety, it is however generally that, people can be in the drawer bin in house Upper installation electronic lock, then corresponding fingerprint or cipher input is cooperated to complete task of unlocking and be latched, pumping is placed on protection Article in drawer bin, but in real life, people can select the drawout cubicle that volume is smaller, concealment is strong to place wealth mostly Object, this causes the interior accommodating space of drawout cubicle will not be excessively roomy, but the mechanism element of door cabinet electronic lock on the market it is numerous, Structure is complicated, and lock body volume specification is generally bigger than normal, causes the drawout cubicle for having installed electronic lock additional that can further compress the storage in cabinet Object space is greatly lowered the quantity for placing article of drawout cubicle.

Summary of the invention

For overcome the deficiencies in the prior art, the present invention provides a kind of highly-safe, simple drawout cubicle micro electric of structure Son lock.

The technical solution adopted by the present invention to solve the technical problems is:

A kind of drawout cubicle minitype electronic lock, including the open lock housing in front right two sides are installed on the end face on front side of the lock housing There is locking closure, circuit board is installed in the lock housing and shaft is connected to latch bolt block in the lock housing, is equipped in the lock housing For limiting the retaining mechanism of the latch bolt block, the latch bolt block is provided with outer tongue and interior tongue, and the latch bolt block is in level Direction is convex a transmission tongue, the retaining mechanism include slide solid lock plate that iron core, spring, shaft are connected in the lock housing and with The magnetic red block of the circuit board electrical connection, the magnetic red block are provided with sliding groove, and the solid lock plate is divided into upper lock plate and lower locking plate, And the two is provided with guide hole, one end setting of the sliding iron core in forming angle on horizontal plane in the plate face of the lower locking plate There is limit plate, after assembly, the other end of the sliding iron core sequentially passes through the guide hole and spring and protrudes into the sliding groove, The outer tongue is stretched out from the right side of the lock housing, and the bottom of interior tongue and the top surface of the upper lock plate end are affixed.

Two-way torsional spring is installed in the lock housing, the spring coil of the two-way one end of torsional spring is connected with the interior tongue shaft, The spring coil of the other end is sleeved on the fulcrum in the lock housing.

The area of the limit plate, guide hole and sliding iron core three gradually successively decreases.

The transmission tongue and the outer tongue form angle, and angular range is 90 °~110 °.

Side of the latch bolt block between the outer tongue and the interior tongue is the scallop with 2~3 radians.

The angular range of the upper lock plate and the lower locking plate is 85 °~100 °

Wire guide is provided on the locking closure.

The beneficial effects of the present invention are: the present invention is mainly connected to the lock in lock housing by lock housing, locking closure, circuit board, shaft Tongue block and retaining mechanism for limiting latch bolt block, which combine, to be constituted, and transmission tongue is provided on latch bolt block, and retaining mechanism includes sliding Iron core, spring, solid lock plate and magnetic red block, circuit board can be that magnetic red block powers on magnetisation according to received switched electrical signal, allow magnetic Spring block, which is attracted sliding iron core, gets out of the way the limitation to latch bolt block to touch extruding solid lock plate, so that user can direct pull drawer Door picks and places article, it is only necessary to which a small number of mechanism elements is just able to achieve the switch locking function of electronic lock, and structure is simplified, can be effectively The volume specification of lock body is reduced, the storage space for occupying drawout cubicle is reduced.
