Detailed Description

As shown in fig. 1-4, the present invention relates to a safety angle blade lock, which comprises a lock case 1, a plurality of blades 2, a lock core 3, a blocking piece 4, a shifting piece 5, a lock bolt 6, a lock bolt spring 7, a nut 8 and a key 9.

The lock core 3 is sleeved in the middle hole 11 of the lock shell 1 in a clearance mode, the separation blade 4 and the shifting piece 5 are sequentially sleeved on the inner side section of the lock core 3, the nut 8 is fixedly screwed on the threaded column 31 at the inner end of the lock core 3, and the separation blade 4 and the shifting piece 5 are fixed on the lock core 3; the lock core 3 is an integrated structure, and a plurality of blade chambers 32 (as shown in fig. 5 and 6) are arranged on the lock core, and openings of the blade chambers 32 are opened along the radial direction and are arranged side by side at intervals.

As shown in fig. 8, the middle of the blade 2 has a through slot 21 for a key to pass through, the inner wall of the through slot 21 is provided with a rib 22 matched with the key, the outer wall of the blade 2 is provided with a password groove 23, and the blades 2 are movably mounted in the blade bins 32 of the lock cylinder 3 respectively; the lock bolt 6 is movably arranged between the inner wall of the hole 11 in the lock shell 1 and the lock core 3, a lock bolt spring 7 is arranged between the top surface of the lock bolt 6 and the lock shell 1, the bottom surface of the lock bolt 6 is abutted against the blade 2, and the lock bolt 6 can fall into the code groove 23 on the outer wall of the blade 2.

Referring to fig. 9, the key 9 is inserted into the lock cylinder 3, the insertion portion of the key 9 is axially provided with a long groove 91, the long groove 91 is a snake-shaped rail 91, and the blade 2 can rotate initially when inserted, an inlet of the snake-shaped rail 91 is arranged at the insertion end of the key 9, and the snake-shaped rail 91 is matched with the ribs 22 on the blades 2 to allow the ribs 22 on the blades 2 to slide in.
