Detailed Description

Embodiments of the present invention will be further described with reference to fig. 1 to 2. The structures, proportions, and dimensions shown in the drawings and described in the specification are only for the purpose of understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is in any way obvious to those skilled in the art, and modifications and variations of the structures, proportions, and dimensions can be made without departing from the spirit and scope of the present disclosure. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The utility model provides a fire prevention lock with open simultaneously or close square tongue and oblique tongue function, includes the lock shell, is located oblique tongue mechanism and square tongue mechanism on the lock shell, oblique tongue mechanism includes oblique tongue subassembly and oblique tongue torsion assembly, square tongue mechanism includes square tongue subassembly and square tongue torsion assembly, the oblique tongue subassembly includes oblique tongue and connecting rod, the cover is equipped with oblique tongue support on the connecting rod, sliding fit on the lock shell is assembled to oblique tongue support, oblique tongue torsion assembly includes the oblique tongue torsional spring that the drive connecting rod resets, square tongue subassembly includes square tongue and driver part, square tongue torsion assembly includes the lock core thumb wheel, the last actuating arm that is equipped with of driver part, the one end of actuating arm extends towards the lock core thumb wheel, and inconsistent with the lock core thumb wheel, and the other end extends towards oblique tongue support, and inserts to establish and fix in oblique tongue support. The oblique tongue torsion assembly further comprises a torsion part and an oblique tongue shifting piece, one end of the oblique tongue shifting piece is abutted to the torsion part, and the other end of the oblique tongue shifting piece extends to the oblique tongue support and is abutted to the head end of the oblique tongue support. The driving part comprises a square tongue shifting piece, a baffle and a baffle torsional spring for driving the baffle to reset, the driving arm is fixed on the square tongue shifting piece through a rivet, the square tongue shifting piece is in sliding fit with the baffle in the left and right directions, and the baffle is in sliding fit with the shell in the up and down directions.

The working principle is as follows: when the lock is unlocked, the lock cylinder thumb wheel is operated in a rotating mode, the driving arm is driven to move, the driving arm is in insertion fit with the latch bolt support, the latch bolt support is driven to move towards the inside of the lock shell when the driving arm moves, the latch bolt support drives the latch bolt assembly to move towards the inside of the lock shell, the latch bolt torsion spring is sleeved on the rivet, one end of the torsion spring abuts against the inner wall of the lock shell, the other end of the torsion spring is fixed on the connecting rod, when the connecting rod moves towards the inside of the lock shell, the torsion spring is in a deformation state, and at the moment, the latch bolt is in an opening state.
