Description
Technical field
The invention belongs to the lockset apparatus field, be specifically related to a kind of protector of mortise door lock core.
Background technology
Mortise door lock is because of cheap, and its usage degree has obtained popularization and application.Yet it is as safety device, its anti-violence damage capability is on the weak side always, its reason is that the volume of door lock core is less, and the internal construction spatial arrangement is tight, and the latching structure of lock core and lock body is too weak, causes the saboteur only need insert lockhole to screwdriver with one, different directions is twisting firmly, lock core will be destroyed, rotates thereby break away from lock body, causes the safe condition of locked object to be subjected to very big threat; And the price of electronic lock, coded lock is quite expensive, therefore how to provide the high mortise door lock of a kind of degree of safety to seem particularly necessary.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of protector of mortise door lock core, arrange by protective cover and protective cover internal construction to lock core, to reach the purpose of security protection.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of protector of mortise door lock core comprises protective cover, the fastening cover and the lockhole protecting cover that are arranged at described protective cover bottom and match with it, and described protective cover is identical with the lock core shape, and described protective cover is the integrally casting moulding; The thickness at described protective cover top is greater than the thickness of sidepiece; Lock core is positioned in the described lockhole protecting cover, and the periphery of described lockhole protecting cover is provided with fixture; Described lockhole protecting cover and described fixture all place described protective cover inside.
Further, also comprise screw, be provided with through hole at described fastening cover, be provided with helicitic texture in the described through hole, described screw can pass through hole and object is affixed.
Further, also comprise trim, be provided with through hole at the sidepiece of described trim and described protective cover, can described trim and described protective cover be fixed by securing member.
Preferably, the top of described protective cover and sidepiece junction are ramp structure.
Preferably, the material of described protective cover is high-carbon steel.
Pass through technique scheme, the present invention is by being cast into protective cover one and thickening the protective cover top thickness, and simultaneously in the inside of protective cover, the lockhole protecting cover is set up in the periphery of lock core, promote the outside and inner firmness of mortise door lock, strengthened the degree of safety of locked object.
