During use, the utility model Multiple locking point device is installed in the last lower edge of the both sides up and down of main lock near door, on the doorframe of hexagonal pin corresponding position, offer slotted eye, utilize key or main lock the last lower drawing block of hand control master lock or world pulling block are moved, this connecting rod that moves through passes to pulling block on the Multiple locking point device, pulling block directly drives hexagonal pin stretching motion and centering block rotates, the centering block rotation has promoted main tongue pin and has made stretching motion in the horizontal direction, so just realized with key or handle locking or when opening main lock, locking or opened the Multiple locking point device of door.

This usefulness is novel to have following characteristics:

(1) the centering block structure makes moving both vertically of connecting rod easily change the horizontal movement of main tongue pin into, and makes the main tongue pin motion of Multiple locking point device light, flexible, thereby very light when using key switch master lock and Multiple locking point device, no jam phenomenon appearance;

(2) design of main tongue pin resetting means, can eliminate fully by the last lower drawing block of main lock or the accumulation gap of world pulling block, connecting rod, Multiple locking point device pulling block and inner packet generation thereof, main tongue pin can be in fully to be stretched out or the retraction state, make the action of unlatching, locking of Multiple locking point device smooth and easy, flexible, effectively avoid because the generation of " half-dead point " phenomenon of not unblanking that alignment error or gap accumulation are caused;

(3) the hexagonal pin adopts long bolt, the swivel nut syndeton that can regulate length, this mechanism is easily mounted on the door Multiple locking point device, and the installation site that can proofread and correct the hexagonal pin effectively, make it concordant with the reveal face, reach effect attractive in appearance, the pin of hexagonal section and have the pin cap design of hexagonal endoporus can effectively prevent hexagonal pin and swivel nut loose or dislocation;

(4) Multiple locking point device profile fitted position and the pulling block screw that is connected with connecting rod thereof all adopt symmetric design, and it is installed in when last, can make no distinction of rank and about, use very convenient.

In sum, it is easy, easy to operate that the utility model is installed, and after being installed in door and going up, can effectively increase the lock point of door, the locking function and the antitheft effect that improve door.
