Abstract
A kind of anti-drilling safety cabinet is locked, and relates to the lock technology field of specific use, and series connection screw (3) front portion at lockset rear portion is provided with alloy head (4).Its series connection screw (3) is designed to one with alloy head (4), make safety cabinet lock (1) firmer, can prevent effectively that drill bit from destroying core rear portion series connection screw, making main lock connect guide strip (2) can not to come off and safety cabinet lock (1) is vowed and go its function, even the burglar uses bit drills to go bad core in the short time, alloy head on the series connection screw forms obstacle again, after the drill bit that the burglar bores runs into the alloy head, because the alloy head adopts non-flat design, drill bit thereby meeting produce fracture along its inclined-plane operation, the burglar can't be opened, thereby be difficult to implement theft.
Description
Technical field:
The utility model relates to the lock technology field of specific use, especially a kind of anti-drilling safety cabinet lock.
Background technology:
At present, the stolen incident of safety cabinet happens occasionally, destroy by method in order to adopt sledge at the safety cabinet door lock, pound etc. for its general theft means, open safety cabinet, these methods waste time and energy, so some burglar brings into use miniature brill or other to bore damage insurance cabinet lock, use these instrument crime times short, vow and steal the rate height, cause the country and people's property loss heaviness.
Summary of the invention:
Can not resist the defective of bit drills for overcoming existing safety cabinet lock, the purpose of this utility model provides a kind of anti-drilling safety cabinet lock.This anti-drilling safety cabinet lock can not only be resisted various bit drills, and is firmer, and the unusual end of cost.
For achieving the above object, the utility model adopts following technical scheme:
This anti-drilling safety cabinet lock, it comprises lock body, and the series connection screw front portion at lockset rear portion is provided with the alloy head.
This anti-drilling safety cabinet lock, its series connection screw and alloy head can be designed as one.
This anti-drilling safety cabinet lock, its alloy head can be designed to convexity, truncated cone, dihedral, beveled.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This anti-drilling safety cabinet lock, the unique alloy head design of its series connection screw, make the safety cabinet lock firmer, can effectively prevent from drill bit destruction core rear portion series connection screw, main lock connection guide strip can not be come off and safety cabinet is locked to vow and go its function, even the burglar uses bit drills to go bad core in the short time, alloy head on the series connection screw forms obstacle again, after the drill bit that the burglar bores runs into the alloy head, because the alloy head adopts non-flat design, drill bit thereby meeting produce fracture along its inclined-plane operation, the burglar can't be opened, thereby be difficult to implement theft.
