Safe burglarproof door lock with longitudinal cylinder lock core
A key is inserted into an oval keyhole 3 to push up a longitudinal cylinder 5 and an ejecting pin opening cylinder 17-1, and a matched lock core 8 and a cylinder 10 which are in a longitudinal cylinder hole 4 are pushed back into a matched lock core cylinder hole 9 to be separated. Meanwhile, the ejecting pin opening cylinder 17-1 is also pushed into a share eccentric opening hole 21 to push and press an ejecting pin opening locating cylinder 17-2 into an eccentric opening bolt seat 16, so that the share eccentric opening hole 21 is separated from the ejecting pin opening locating cylinder 17-2. Meanwhile, the key, a longitudinal cylinder lock core 2 and a top end edge U-shaped inner opening key 7 are made to rotate, and a 60-degree cylinder 13 is moved upwards to move a lock body safe cylinder 15 in a cylinder hole 12 in the middle of a safe lock core 11 into a lock body cylinder hole 14, so that the safe lock core 11 is separated from a lock body 1, and the longitudinal cylinder lock core 2, the safe lock core 11, the matched lock core 8 and the ejecting pin opening cylinder 17-1 rotate together. An opening device 20 and an opening tongue 22 are driven to rotate, and a mechanical insert pin is pushed in a door frame to lock a door.
