Description

Rack-and-pinion is opened the fast lock of two grades of dead bolt corners, 90 degree

Technical field

The utility model relates to a kind of pick-proof door lock technical field, is suitable for installing and using on various anti-forcing open the door.

Background technology

At present, the pick-proof door lock is of a great variety, the interlock lock that generally uses on the market as multiple spot locking, its structure is by a lock core, and the master locks and is equipped with two is or three dead bolts to be card edge type, dead bolt is circular or square, lock core is outward a lock body, is connected with main lock tongue by connecting rod, is connected with outer locking bar by long up and down connecting rod simultaneously, a lock core rotates a plurality of lock point lockings that just can make door by machine driving, also can reach effect same by handle drives simultaneously, the advantage of this kind door lock, simple in structure, produce easily, easy to install and use, but its weak point is the pick-proof weak effect, operates cumbersome.

Goal of the invention

For solving the deficiency of above pick-proof door latch structure, the purpose of this utility model provides a kind of main fast lock of two grades of dead bolt corners of board-like unlatching, 90 degree that drives, this lock mainly drives dead bolt by the main drive plate that slides and at first revolves the interlock mode of locking then that turn 90 degrees, and dead bolt is realized the purpose of fast lock and raising pick-proof performance for having oval end structure by the movable lug interlock.

Structure design of the present utility model is achieved in that the utility model master drives its structure of the fast lock of two grades of corner dead bolts of board-like unlatching corner, 90 degree and includes lock box, dead bolt and transmission mechanism, its structure as shown in Figure 1, the utility model characteristics are that the lock box front is a decorative panel, with perpendicular corresponding three the rotation dead bolts that are equipped with of this plate lockhole, main drive plate is equipped with on parallel lock box plane below this dead bolt, just have parallel right angle chute at main drive plate accordingly with the rotation dead bolt, the structure of each rotation dead bolt is cylindrical in the middle of being, the outer end is oval termination (as shown in Figure 2), the inner end vertical headers is fixed with pin, pin inserts in the chute of corresponding main drive plate, and corner dead bolt fixed head is equipped with in this inboard, rotation dead bolt two ends; The pressure handle driver is equipped with on lock box top, and the pressure handle power transmission shaft by the centre is connected with rotating shaft with main drive plate with the corner junction plate; On the main drive plate drive spring is housed; Level is equipped with movable lug above the lock box, and this movable lug back is fixed with displacement blocks automatically, is contact above the card automatically, and is relative with the movable lug rear end, below the card protrusion dop arranged automatically, joins with main drive plate side teeth; To be teeth be connected with gear on the lock body of center in main simultaneously drive plate side, interior lock shaft is housed below the lock box, is fixed with corner junction plate up and down simultaneously at main drive plate, so that be connected with other locking bar, be the lock box cover plate above the lock box, whole lock members is fitted together in aggregates.

Advantage of the present invention: this lock structure is simple, and is easy to install, and outstanding feature pick-proof performance is good, and locking is fast, and the life-span is long.

The specific embodiment

Its structure of the utility model and operating principle are described in detail by embodiment.Its structure of the utility model such as Fig. 1, shown in 2, lock box 1 front is a decorative panel 11, with perpendicular corresponding three the corner dead bolts 12 that are equipped with of decorative panel 11 lockholes, main drive plate 8 is equipped with on parallel lock box plane below dead bolt 12, have parallel right angle chute at main drive plate 8 with dead bolt 12 corresponding places, the structure of each corner dead bolt 12 is cylindrical in the middle of being, the outer end is oval termination (as shown in Figure 2), the inner end vertical headers is fixed with pin, pin inserts in the chute of corresponding main drive plate 8, corner dead bolt fixed head 13 is equipped with in this inboard, dead bolt two ends, pressure handle driver 3 is equipped with on lock box 1 top, pressure handle power transmission shaft by the centre and corner junction plate and main drive plate 8 are connected with rotating shaft, on the main drive plate 8 drive spring 5 is housed, level is equipped with movable lug 2 above the lock box 1, movable lug 2 back are fixed with displacement card 4 automatically, displacement is a contact above the card 4 automatically, relative with the movable lug back, automatically be the protrusion dop below the card 4, be connected with main drive plate 8 side teeth, to be teeth be connected with gear on the center lock body 6 in main drive plate 8 sides, lock shaft 7 in being equipped with below the lock box 1, be fixed with corner junction plate 10 and 9 up and down simultaneously at main drive plate 8, so that be connected with other locking bar, above the lock box lock box cover plate, whole lock members is fitted together in aggregates.

Its course of work: at first door lock is in closed condition, sideway swivel pressure handle driver or in the door from outer side of door key rotary locking cylinder, this pressure handle is by the corner junction plate, its center lock body can make main drive plate move up (as shown in Figure 1) by tooth bar and since the pin of corner dead bolt in the chute of main drive plate along with slip, divide two grades and carry out, one grade of corner dead bolt revolves and turn 90 degrees, second gear dead bolt termination is reduced in the oval breach of decorative panel, above movable lug open simultaneously, this moment, door was opened;

When locking a door, as long as door is shut gently, at this moment movable lug is inwardly withdrawn, and blocks automatically by displacement to discharge main drive plate, because the effect of drive spring, corner dead bolt snap back skids off, and revolves after skidding off to turn 90 degrees, and this moment, door was a lock-out state, so the lock of expressing one's gratification.
