Detailed description of the invention
As depicted in figs. 1 and 2, the anti-theft device of door lock the utility model proposes is arranged on door lock, door lock is installed on a body 1, door lock comprises lock core 3 and outer panels 2, lock core 3 protrudes outer panels 2, lock core 3 is provided with keyhole 31, and door lock is the upper conventional lock of installing of door in our daily life here.
This anti-theft opening apparatus comprises locking closure 4, rivet shaft 5, bearing pin 6 and sleeve 7, locking closure 4 is located in the outer panels 2 of door lock, the two ends of locking closure 4 are respectively equipped with the first through hole 41 and the second through hole 42, between the first through hole 41 and the second through hole 42, be provided with cavity 43, cavity 43 is relative with the lock core 3 of door lock, make locking closure 4 cover the keyhole 31 on lock core 3, locking closure 4 is long strip type here.
Outer panels 2 is provided with the riveted holes 22 relative with the first through hole 41, and be provided with the internal thread hole 21 relative with the second through hole 42, rivet shaft 5 one end are passed successively the first through hole 41, riveted holes 22 and are riveted in outer panels 2, locking closure 4 can rotate as axle center up and down taking rivet shaft 5, to expose the keyhole 31 on lock core 3, open door lock.
Shown in Fig. 3 to Fig. 5, bearing pin 6 is cylindrical, and the front portion 61 of bearing pin 6 is provided with the external screw thread coordinating with internal thread hole 21, and the rear portion 62 of bearing pin 6 is positioned at the second through hole 42 and is provided with latch. Sleeve 7 inwalls are provided with the draw-in groove coordinating with latch 621, and sleeve 7 one end are provided with turns round handle 72, between the outer circumference surface of bearing pin 6 and the inwall of the second through hole 42, is provided with gap, and anterior these gaps of inserting of sleeve 7 coordinate with bearing pin 6, sleeve 7 and to turn round handle 72 one-body molded.
