Abstract

The utility model relates to a multifunctional trifarious lock for a theft prevention door, which is controlled by a rotating wheel and a cam. The utility model is composed of a handball, a marble lock, a key, a plate angle, the rotating wheel, a positioning post for a movable tongue, a jack, the cam, a solid tongue, a cover plate for a lock body, a movable tongue, a torsion spring, a lock body, a connecting plate, a composite sleeve for a lock body, and a plate angle for a solid tongue, wherein, under the action of the torsion spring, part of the movable tongue is exposed out of the lock body; When the theft prevention door is closed, the inclined surface of the movable tongue is stressed to move in the lock body, and one end of the tail part of the movable tongue is positioned in the notch of the rotating wheel to drive the rotating wheel to leave and the plate angle to rotate. After the theft prevention door is closed, under the action of the torsion spring, the movable tongue resets, and the theft prevention door which is closed is immediately locked. A key is used to rotate a lock core, the plate angle for a solid tongue, and the solid tongue which are simultaneously move, and trifarious locking is realized. The cam is rotated by the handball, and the theft prevention door can be opened indoors. The movable tongue locks a safety, and the prevention door can be opened forever.

Description

Multi-functional three-dimensional safe-guard door lock with runner, cam control

The utility model provides a kind of multi-functional three-dimensional safe-guard door lock with runner, cam control.Belong to five metals lockset kind product.

Along with the rise of security door, multiple safe-guard door lock has appearred, and wherein multi-function door lock is to realize multi-direction locking with a lock.The multi-function door lock that existing market occurs can be divided into two kinds: a kind of is to drive multidirectional dead bolt with handle by transmission mechanism, then with locking the transmission mechanism locking; Another kind is directly to drive transmission mechanism with key, and the back locking puts in place.They have the following disadvantages: because the same moved further of multi-direction dead bolt is opened the door, closed the door and all must use key, do not possess the function that common door lock movable lug is closed the door and promptly locked; For the multi-function door lock that uses handle, because of handle is being damaged outdoors easily.For addressing the above problem, the utility model provides a kind of multi-functional three-dimensional safe-guard door lock with runner, cam control.

This lock is made up of handball, ball lock head, key, Ban Jiao, runner, active tongue locating pillar, very heavy, cam, slow-witted tongue, lock cover, movable lug, torsion spring, lock body, junction plate, lock body combination cover, solid tongue plate angle.

Movable lug is subjected to the torsion spring effect, and part is exposed at outside the lock body, closes the door to make that the movable lug inclined-plane is stressed to be moved in lock body, just drives runner and leaves the plate angle and rotate because of movable lug afterbody one end is positioned at the runner breach.Close behind the door, under the torsion spring effect, movable lug resets again, the i.e. lock of realizing closing the door.

Rotate counterclockwise key, runner is stirred at the plate angle that is contained in the lock core afterbody, and runner breach wedge angle promotes movable lug and moves outside lock body, and movable lug drive junction plate, solid tongue plate angle, slow-witted tongue move, and realize the three-dimensional locking.The runner breach leaves after the movable lug afterbody, should continue to change an angle and just can take off key, and the garden cylinder of runner contacts with the garden cambered surface of movable lug afterbody, the three-dimensional dead bolt can't be return reach self-locking.

Clockwise rotate key, runner is stirred from other direction in the plate angle, the runner breach moves into the movable lug afterbody, another wedge angle pulling movable lug afterbody of runner breach, movable lug is moved in lock body, when an end of movable lug slotted hole contacts with the junction plate uvula, just drive junction plate, solid tongue plate angle, slow-witted tongue moves together, realize that the three-dimensional dead bolt opens.For the situation of promptly locking of closing the door, be that movable lug moves when unblanking.The movable lug stroke is limited by movable lug slotted hole and active tongue locating pillar.

Can realize indoor unlatching with the handball rotating cam, permanent unlatching, the insurance of movable lug locking.

Under the lock situation of closing the door promptly, clockwise rotate handball and drive cam rotation, the cam left end is stirred the movable lug afterbody, and movable lug is retracted in the lock body, and lock is opened.In the time of in movable lug is retracted into lock body, handball is pulled back, the protruding garden post of cam upper surface is entered in the corresponding hole of lock cover, this moment, the cam left end still contacted with the movable lug afterbody, and movable lug can't be moved, and can reach permanent unlatching.Rotate counterclockwise handball and drive cam rotation, the cam right-hand member can't move movable lug very heavy jack-up backward, realizes the insurance of movable lug locking.When clockwise rotating handball when driving cam rotation, very heavyly under spring action, reset arming.
