Description

Outside fitting linkage door lock

The utility model be a kind of can be in two or three positions the link fitted outside door lock of locking of opposite house simultaneously.Belong to the haberdashery and hardware class.

The fitted outside door lock of Chu Xianing in the market, key can only be controlled one group of dead bolt in the same lock housing, locking is carried out at the doorframe middle part, because of fixed point has only a place,, stressed concentrating, the impact resistance intensity of door is reduced, the doorframe position that keeper is housed is very easily destroyed, and has reduced the insurance function of lock, for increasing stress point, improve the impact resistance intensity of door, many users install two door locks at the doorframe middle part simultaneously, though improved the impact resistance intensity of door, during because of unlatching, must use two keys respectively lock to be opened, bring many inconvenience to use, and because of the price height, and can not generally use.

The purpose of this utility model is just in order to overcome above-mentioned shortcoming, on the basis of the impact resistant capability that improves door lock, realize interlocking by connecting rod, only need a key to open simultaneously or the locking master, pay lock, make an energy in two or three fixed-site on doorframe, be a kind of esy to use, safe and reliable, cheap and good-quality novel fitted outside door lock.

Accompanying drawing 1 is a fitted outside door lock embodiment floor map.Fig. 2 is a structural representation.1 is main lock among the figure, the 2nd, and connecting rod, the 3, the 4th, pay lock.

The utility model external build-up door lock, (1) pays with one that lock (3) or two pay lock (3), (4) form to it is characterized in that master lock is arranged, master lock with pay lock and connect by connecting rod (2), realize interlock. When with key operated or locking master lock (1) dead bolt, by steering mechanism's transmission in the master lock, drivening rod (2) is mobile, thereby unlatching or locking are paid lock (3) or pair lock (3), (4) dead bolt, and a while is fixed on the doorframe in two or three positions. Thereby increased stress point, alleviated the impact of each stress point. Therefore, improved the impact resistance degree of Men Yusuo.

In addition, main lock (1) is by the multiple flapper lock of known technology fitted outside basic structure, increases to turn to driven axle (7), connection sheet (8), direction turning piece (9), pillar (10) to form, to realize turning to control.

Next, is for ease of installing and using, can be according to the weak spot of door, by changing different connecting rods (2), pair lock (3) or pair lock (3), (4) can be installed on doorframe optional position all around, to adapt to different needs, the impact resistance degree of reinforcement weak spot.

Provide the utility model one specific embodiment below in conjunction with Fig. 1, Fig. 2, further specify the structure and the course of action of this utility model.This embodiment is made up of main lock (1), pair lock (3), (4) and connecting rod (2), comprise tower spring (5), pressing plate (6) again in the main lock, turn to driven axle (7), join sheet (8), direction turning piece (9), pillar (10), tongue drawing plate (11), steering drive axle (12), to realize main dead bolt and connecting rod, the interlock of paying dead bolt.When key inserted the lock core rotation, plectrum rotated in driving, and interior plectrum is depressed pressing plate (6) and made tower spring (5) compression, thereby the tooth that can stir on the tongue drawing plate (11) moves tongue drawing plate.When tongue drawing plate moves, the steering drive axle (12) that is fixed on the tongue drawing plate drives direction turning piece (9), making direction turning piece is that rotate in the axle center with pillar (10), and the driven axle (7) that turns to that is fixed on the direction turning piece moves up and down the connection sheet by the slotted hole on the connection sheet (8), because connection sheet and connecting rod join, connecting rod also moves up and down thereupon.So just can realize main lock and pay the purpose that lock is opened locking simultaneously.

The utility model is rational in infrastructure, and impact resistant capability is strong, and is easy to use, is adapted at places such as family, office and uses.
