SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a simple cabinet door lock aiming at the defects of the prior art, which reduces the labor intensity of manpower, reduces the operation difficulty of workers, is convenient for assembling the cabinet door lock and reduces the production cost.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a simple and easy cabinet door lock, includes lock main part, handle, locking mechanical system, lock main part middle part is equipped with the installation cavity, its characterized in that, the handle distributes in the installation cavity, the installation cavity tip be equipped with can with handle articulated unblock articulated shaft, locking mechanical system includes the key unblock subassembly and the lock core subassembly with the handle linkage, key unblock subassembly include with handle intermittent type nature linkage the lock courage and with the handle laminating frame of lock courage intermittent type nature linkage, the lock main part is located the one end of keeping away from the unblock articulated shaft and is equipped with lock courage mounting hole, the lock courage is installed in the lock courage mounting hole, the handle laminating is erect and is arranged in the installation cavity and distribute in the tip that is close to the lock courage, the lock core subassembly includes the articulated shaft and with the latch hook linkage board of lock core linkage, the lock core links firmly relatively with the unblock.

By adopting the technical scheme, compared with the prior art, the internal structure of the cabinet door lock is simplified, the locking function of the cabinet door lock can be realized by using the least parts, the labor intensity of manpower is reduced, the operation difficulty is also reduced, the cabinet door lock is convenient to assemble, the production cost of the cabinet door lock is reduced, and better benefits are brought to manufacturers; when the lock is used, the handle can be released by rotating the lock liner through the key, the handle is lifted up manually until the handle is separated from the handle attaching frame, then the handle is rotated, the handle further drives the unlocking hinge shaft to rotate, the lock cylinder rotates along with the unlocking hinge shaft, and then the opening of the cabinet door lock is realized.

The simple cabinet door lock can be further arranged as follows: the lock core end part linkage has the latch hook, lock key unblock subassembly still locates the latch hook fixing base of lock core periphery including the cover, latch hook fixing base tip be equipped with latch hook sliding fit's latch hook mounting groove, the lock core can drive the latch hook and make reciprocal linear motion along latch hook mounting groove axis, the handle is located the one end of keeping away from the unblock articulated shaft and is equipped with the locking gangbar that can block with the latch hook.

By adopting the technical scheme, the locking and unlocking of the handle can be controlled by matching the lock hook with the locking linkage rod, the movement track of the lock hook is always kept consistent by further arranging the lock hook fixing seat, the structural stability of the lock core assembly is improved, and the problem that the whole structure of the cabinet door lock is loose due to repeated unlocking is prevented, so that the technical problem of unstable structure in the prior art is solved.

The simple cabinet door lock can be further arranged as follows: the handle laminating frame includes the laminating body and with laminating body integrated into one piece's assembly, be equipped with spacing step between assembly and the laminating body, each side of laminating body is equipped with the radius angle.

By adopting the technical scheme, the step mainly limits the handle, prevents the handle from being excessively inserted into the mounting cavity, and is convenient for a user to lift the handle; and a fillet is further arranged, so that the grip is convenient to be attached to the grip attaching frame, and the interference is prevented.

The present invention will be described in further detail with reference to the accompanying drawings and examples.
