Description

Anti-sticking lock body

Technical Field

The utility model relates to a lock body.

Background

The traditional mechanical lock body mainly comprises a lock shell, a latch bolt rod, a handle thumb wheel, a multi-tooth thumb piece, a square bolt (also called a main bolt), a slip sheet and a linkage sheet, wherein the latch bolt is arranged above the lock shell, the square bolt is arranged below the lock shell, the handle thumb wheel is arranged in the middle of the lock shell, the multi-tooth thumb piece is sleeved outside the handle thumb wheel, the latch bolt rod and the slip sheet are distributed and connected behind the latch bolt and the square bolt, the linkage sheet is arranged on the slip sheet, a sliding groove is arranged on the linkage sheet, a sliding shaft is arranged in the sliding groove and fixed on the slip sheet, one end of the multi-tooth thumb piece is movably connected with the latch bolt rod, the other end of the multi-tooth thumb piece is pivoted with the upper end of the slip sheet, a lock core hole is arranged below the slip sheet, the lock core thumb piece is arranged in the lock core hole, the slip sheet can be stirred to drive the latch bolt to be locked or unlocked after the lock core thumb piece rotates, a thumb piece of the lock core thumb piece can push the linkage sheet to move upwards along the slip sheet after the lock core thumb piece rotates to the lower end of the linkage sheet, the lock core thumb piece is connected with the latch bolt rod, and the latch bolt can be driven to be opened, and the multi-tooth thumb piece to be retracted after the lock core dial wheel is rotated, and the multi-tooth thumb piece is connected with the latch bolt. Because the linkage piece of the lock body can only move up and down along the lock shell through the matching of the sliding groove and the sliding shaft and can not be turned, if the door is opened too urgently or the key is rotated too violently in life, the shifting head of the lock cylinder shifting wheel can often turn over the lower end of the linkage piece and enter the rear side of the lower end of the linkage piece, so that the linkage piece and the shifting head of the lock cylinder shifting wheel are tightly clamped, at the moment, the shifting head of the lock cylinder shifting wheel can not be rotated, and the key is clamped in the lock cylinder and can not be pulled out.

SUMMERY OF THE UTILITY MODEL

In view of the defects of the prior lock body, the technical problem to be solved by the utility model is to provide an anti-block lock body which can not cause the key to be blocked and the lock core to be unable to rotate.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: an anti-jam body comprising: a lock shell, an oblique tongue rod, a main tongue, a sliding sheet, a handle thumb wheel, a thumb sheet and a linkage sheet,
