The purpose of this utility model is to provide a kind of convenient and practical, double door theftproof lock that theftproof performance is good.
For achieving the above object, the employing technical scheme is as follows: the double door theftproof lock is made up of main lock and secondary lock two parts, main lock contains lock housing, tapered end, and secondary lock contains lock housing, particularly in main lock pin, lock hole and the transmission mechanism locked, tapered end links to each other with lock pin by transmission mechanism, lock pin can move in the lock hole, and transmission mechanism is made up of movable plate, location-plate and lock pin control panel, and pair has been locked dead bolt and tongue, dead bolt matches with the lock hole, and the hole of matching with lock pin is arranged on dead bolt.
The dead bolt that pair is locked is half garden column, and the bottom surface of this columnar lock tongue is a plane, and upper bottom surface is an inclined-plane, and the hole of matching with lock pin is arranged on the inclined-plane.
The double door theftproof lock of this structure is provided with lock pin, lock hole main locking, and pair is locked and is provided with dead bolt, and is porose on the dawn dead bolt, because the lock hole is positioned at lock housing inside, this lock is with lock pin dead bolt to be pinned in the lock hole, thereby plays the effect of pick-proof.In addition, dead bolt is half garden column, promptly before and after the two sides be the inclined-plane, tongue is arranged thereafter, therefore, two fan doors are closed in any case, all can be, and can not break door and lock with on the door lock, very convenient and practical.
Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail.
Fig. 1 is the external structure schematic diagram of double door theftproof lock.
Fig. 2 is the internal construction schematic diagram of double door theftproof lock.
Among Fig. 1, the double door theftproof lock is made up of main lock 1 and secondary lock 2 two parts, and main lock 1 contains lock housing 10, tapered end 11, in addition, is provided with a lock hole 12 on main lock 1.Secondary lock 2 contains lock housing 20, in addition, is provided with dead bolt 21 on pair lock 2, and this dead bolt is half garden column, on it porose 22.Among Fig. 2, show the annexation of main lock and secondary each ingredient of lock, also have lock pin 13 and transmission mechanism in the main lock 1, transmission mechanism is made up of movable plate 14, location-plate 15, lock pin control panel 16.Lock pin 13 can move up and down in lock hole 12, its head is the inclined-plane, lock pin control panel 16 is clipped in lock pin 13 and location-plate 15, between the movable plate 14, locating piece 17 is arranged on lock pin control panel 16, draw-in groove 18 on locating piece 17 and the location-plate 15,19 match, lock pin control panel 16 is drawn together with lock pin 13 and is dynamically connected, rotational lock head 11, tapered end 11 promptly contacts with the right side of lock pin control panel 16, and lock pin control panel 16 is promoted from right to left, and locating piece 17 breaks away from from draw-in groove 18, continue to rotate tapered end 11, and then drive movable plate 14 and vertically move down, thereby wholely drive lock pin control panel 16 and lock pin 13 moves down, after locating piece 17 enters in the draw-in groove 19, be locked in place, no longer move down, this moment, lock pin 13 just entered in the hole 22 on the dead bolt, will pin.Breakdown action in contrast, transmission mechanism adopts prior art to realize.Dead bolt 21 on the secondary lock 2 is half garden column, and the bottom is the plane, and top is the inclined-plane, has hole 22 on upper inclined surface, and this hole and lock pin 13 cooperatively interact.Dead bolt 21 links to each other with tongue 23, and is furnished with dead bolt and regains button 24, dead bolt can be regained and discharge.
