Abstract
This invention discloses a bolt-lock structure, comprising: a door handle, a transmission rod, a nut, a support plate, and a semi-screw. The support plate is fixed to the door leaf and protrudes from the edge of the door leaf. The transmission rod is vertically mounted on the support plate, and its end is perpendicularly connected to the door handle. The nut is fitted onto the transmission rod, and the inner diameter of the nut is larger than the outer diameter of the semi-screw. The semi-screw is fixed to the wall. When the door leaf is closed, the transmission rod and the semi-screw approach each other. By fitting the nut onto the semi-screw and connecting them through a threaded structure, the relative position between the door leaf and the wall is locked. This bolt-lock structure achieves rapid and efficient locking of the door leaf.
