Description

Technical Field

[0001] The utility model relates to the technical field of security devices, in particular to a security device for buildings. Background Art

[0002] During the construction process, especially when performing construction work on the elevator shaft, it is necessary to use security devices to protect the shaft opening of the elevator shaft to prevent people from falling into the elevator shaft.

[0003] In the prior art, a Chinese patent with announcement number CN217925008U discloses an elevator shaft protection device, which adopts the scheme of "including an elevator shaft safety door, two guide blocks are slidably connected to the elevator shaft safety door, a mounting plate is fixedly connected to the guide block, a limiting structure is provided on the mounting plate, the limiting structure includes a movable plate, a movable plate is fixedly connected to the mounting plate, a threaded rod is rotatably connected to the movable plate, a limiting plate is threadedly connected to the threaded rod, and a positioning structure is provided on the mounting plate". This scheme is convenient for operators to fix the mounting plate to a suitable position with the cooperation of the positioning structure by setting a mounting plate, a positioning structure and a limiting structure. At the same time, by adjusting the limiting structure, the limiting structure can be closely fitted with the wall or fall off the fitting state, so as to complete the disassembly and assembly of the elevator shaft safety door, all without the aid of auxiliary tools, and the operation is simple and quick, reducing the difficulty of operation for operators.

[0004] However, the above scheme still has some shortcomings.
