Door/window burglar mesh device

Abstract

The invention discloses a door / window burglar mesh device, and relates to the technical field of burglar meshes. The door / window burglar mesh device comprises a door / window burglar mesh device body and connection reinforcement columns; one side of the door / window burglar mesh device body is fixedly connected with one ends of the connection reinforcement columns; the bottom of the inner wall of anarc-shaped sliding top box is fixedly connected with an elastic force return spring; and one end of a supporting connection rod penetrates through the arc-shaped sliding top box and extends to the outside of the arc-shaped sliding top box. According to the door / window burglar mesh device, through combination of the elastic force return spring, the arc-shaped sliding top box, the supporting connection rod, a foot sliding contact plate and a sliding roller wheel, when a burglar slides downwards from the top, the foot sliding contact plate of the door / window burglar mesh device drives the supporting connection rod to slide downwards, meanwhile, the sliding roller wheel slides on the surface of a roller wheel contact groove, feet of the burglar cannot effectively tread a stable burglar mesh top structure, thus, the burglar cannot successfully enter a house of a resident downstairs, and the behaviors of theft of burglars are effectively decreased.
