Description
The utility model is a kind of lockset, the dual fail-safe bidirectional theftproof lock that uses on particularly a kind of security door.
The reversible lock that uses on the security door is the upper and lower action of rotation promotion connecting rod by a handgrip mostly now, reaches locked purpose.The lockset of this structure is not owing to lock safeties, thus indoor locked after, can be opened outdoor, outdoor locked after, also can be opened indoor.So in a single day, the burglar is arranged by in the window inlet chamber, can open door very easily after the crime, the goblin goblin who runs away by door.
The purpose of this utility model provides a kind of novel theftproof lock, and it can overcome existing shortcoming in the prior art, and it has the locking safeties, so after a side of door is dead with door lock, can not open it at the opposite side of door.
The purpose of this utility model is achieved in that it comprises housing and handle, it is characterized in that fixing on the handle cam, have an arcuate slot on the cam, with handgrip is coaxial a gear is housed, have a protruding thorn above the gear, be stuck in the slit of cam, a tooth bar is respectively meshed in the both sides of gear, fix a scotch on the tooth bar, side at housing is installed a locking plate, and an end of locking plate is hinged on the housing, and spring is housed on the hinge, spring one end withstands on the housing, and the other end withstands on the locking plate.
