Description
Technical field:
The present invention 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.
Though above-mentioned utility model must use key operated mode to improve the sense of security by adopting inlet/outlet, strengthened antitheft performance, but still there is following weak point in actual applications in it: 1, this have the safety door latch of rotary pin tumbler lock head because the shared volume ratio of its internal construction is bigger, especially the setting of its safeties has increased the volume of door lock more, therefore this safety door latch with rotary pin tumbler lock head only is adapted to be mounted within on the inner trim panels of a body, and its rotary pin tumbler lock head is to fixedly connected with door lock after passing the balustrade exterior panelling of a body and doorframe, this mounting means is extremely insecure, allows the person that illegally enters the house pry open safety door latch easily and enters in the house; 2, since swing arm one end in the above-mentioned safety door latch with rotary pin tumbler lock head be 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, they otherwise 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.
Summary of the invention:
The technical problem to be solved in the present invention is, provides on a kind of doorframe that can firmly be installed between the inside and outside decorative panel, safety is higher and the rotary marble safety door lock that can also door can be closed under the situation of not locking a door.
Technical solution of the present invention is that a kind of rotary marble safety door lock with following structure is provided: comprise cover plate, housing, big dead bolt device, little dead bolt device, ball lock head and handle revolving part; Be provided with the fixing fixedly riveting part of pegging graft of lock core afterbody of the sub-tapered end of ammunition feed in the described housing; Described fixedly riveting part is provided with first swing arm that can control the guide strip activity; It also comprises the housing capping that is connected with housing; Have big dead bolt through hole and little dead bolt through hole in the described housing capping; Described cover plate has two and have the handle installing hole; Described ball lock head have two and equipped respectively on the cover board; The top link of described handle revolving part is connected on the little dead bolt device; Be connected with the push pedal that the following swing arm with the handle revolving part by first swing arm control is used on the described big dead bolt device; The top link of described handle revolving part is connected on the little dead bolt device and refers to, is with a portable plate on the dead bolt mobile jib of described little dead bolt device; Described top link is enclosed within on the dead bolt mobile jib and between the location-plate I and portable plate of little dead bolt device; Described push pedal flexibly connects with big dead bolt device and refers to, is provided with two chutes in the middle of the described push pedal, and described chute flexibly connects with big dead bolt device by the column that is fixed on the big dead bolt; The lower end of described push pedal is connected with an extension spring, and the other end of described extension spring is fixedly connected on the bottom of housing.
After adopting above structure, compared with prior art, the present invention has the following advantages: after adopting the structure of two cover plates, two ball lock heads and a housing capping, rotary marble safety door lock of the present invention just can be fixedly mounted on the doorframe between the inside and outside decorative panel more, the safety that has improved safety door latch.In addition, when safety door latch was in open mode, the big dead bolt in the big dead bolt device was retracted in the housing, and the little dead bolt in the little dead bolt device can be positioned at little dead bolt box, thereby make door still be in closed condition, thereby satisfied that some house owners want to close the door but the requirement not wanting to lock a door.Also just because of therefore the effect that the present invention also can close the door when can realize not locking a door is gone out the house owner and saved the process that opens the lock with the key together, making gos out becomes very convenient.
Be with a portable plate on the dead bolt mobile jib of described little dead bolt device, described top link is enclosed within on the dead bolt mobile jib and in the location-plate I and the structure between the portable plate of little dead bolt device and can the house owner pinning under the situation of big dead bolt, uses little power rotating handles just can easily door be opened.
Be provided with two chutes in the middle of the described push pedal, described chute can make the house owner also little dead bolt be opened when using key to open big dead bolt by the column that is fixed on the big dead bolt with the structure that big dead bolt device flexibly connects, and has simplified the program of unblanking.
The lower end of above-mentioned push pedal is connected with an extension spring, the structure that the other end of described extension spring is fixedly connected on the bottom of housing can make push pedal after little dead bolt is opened, can return rapidly can be to original position, thereby realizes the effect that also can close the door when not locking a door better; Simultaneously, the house owner also can use handle to carry out operation to little dead bolt device.
