Abstract

The invention provides a door lock device which comprises a positioning block, a locking block and a drive rod, wherein the positioning block is mounted on a door body; the locking block and the driverod are respectively hinged to a door frame; a platform, an oblique surface and a slope are arranged on the locking block; a drive sheet is mounted on the drive rod; during door locking, the drive rod is rotated, and the locking body rotates towards the door body through matching between the drive sheet and the oblique surface of the blocking block; then the locking block is driven under the drive of the drive rod and the slope of the locking block, and the rotation of the locking block can apply a locking force onto the door body till when the door body is tightly closed, the drive rod is propped against the platform of the locking block. The door lock device is simple in structure and convenient to operate, and the locking of the door body is extremely accurate and stable.

Description

technical field [0001] The present invention relates to a device for locking an openable door. Background technique [0002] A door is an entity installed at the entrance and exit of a building to divide a limited space, and a door lock is a device that locks the door in a closed state.
