Description

A kind of rotary marble safety door lock

Technical field:

The utility model relates to a kind of door lock assembly, specifically is a kind of rotary marble safety door lock with rotary pin tumbler lock head.

Background technology:

A kind of notice of authorization number is called the safety door latch with rotary pin tumbler lock head for the CN2913538Y name utility model patent is disclosed on the China national intellectual property board web, it comprises cover plate and housing, described cover plate is equipped with first guide and the fixture that is shaped on first through hole, described housing is installed second guide and the jump ring that is shaped on second through hole, the first guide shift fork and the second guide shift fork can in the opposite direction rotate and connect the activity of control guide strip, described guide strip connects the open and close lock device of big dead bolt and little dead bolt, first through hole is equipped with first rotary pin tumbler lock head, and the shift fork of described first rotary pin tumbler lock head on first guide connects the control guide strip; Second through hole is equipped with second rotary pin tumbler lock head, and the shift fork of described second rotary pin tumbler lock head on second guide connects the control guide strip; Described big dead bolt open and close lock device comprises mutually and equipped to be connected big dead bolt on the big dead bolt mount pad, to be arranged on location lid on the big dead bolt mount pad, to be connected torsion spring that the location covers, to be connected the guide strip that is used with torsion spring and to be fixed on the housing with locating and cover and lead that guide strip is used; Described little dead bolt open and close lock device comprises mutually equipped little dead bolt, the guide peg that is connected with little dead bolt, swing arm and is located at keeper, spring, locating piece, compressing spring and pad on the guide peg successively, described pad is fixed on the end of guide peg with screw, described swing arm one end is connected on the big dead bolt mount pad by another lead, and its other end is to be plugged on the slotted eye of keeper.In addition, safeties also are installed in the housing of this utility model, these safeties comprise equipped mutually security insurance button, slide block, locating piece, torsion spring, pendulum and screw, these safeties be with little dead bolt open and close lock device in the locating piece corresponding matching, be that the spin safe stop button can remove to keep off the locating piece that connects in the little dead bolt open and close lock device by moving slider, open and close thereby control little dead bolt open and close lock device.

There are following two weak points in actual applications in above-mentioned utility model: 1, swing arm one end in the above-mentioned safety door latch with rotary pin tumbler lock head is connected on the big dead bolt mount pad by a lead, its other end is to be plugged on the slotted eye of keeper, therefore big dead bolt and little dead bolt move simultaneously, and the safeties in the housing also are used with little dead bolt device, though the globality of this structure is more intense, but their mode of occupation is more single, promptly or big dead bolt device and little dead bolt device are used simultaneously, or big dead bolt device, little dead bolt device and safeties three use simultaneously; Just because of big dead bolt and little dead bolt move simultaneously, be big dead bolt and little dead bolt or be positioned at big dead bolt box simultaneously and little dead bolt box, be positioned at the housing of this safety door latch simultaneously, therefore when safety door latch is in open mode, the door body can't be closed, and this wants to close the door to some but the house owner that do not want to lock a door has brought certain inconvenience; Though 2 these safety door latchs with rotary pin tumbler lock head must use key operated mode to improve the sense of security by adopting inlet/outlet, strengthened antitheft performance, but brought certain trouble also at every turn going out of house owner, because all will use one time key before he gos out at every turn, if and do not want to use key when going out, just door lock can not be lived after then entering, this has brought unsafe factor for life and property of house owner.
