[0035] The working principle of the utility model will be further described below.

[0036] In the installation process, according to the installation environment of the elevator, the side guard 120 with different sizes of notches 121 is selected, so that the side guard 120 can be stably installed into the elevator shaft; then, the front guard 110 and the rear guard 130 are installed on both sides of the side guard 120 by welding; then, the movable assembly 200 is installed on the front guard 110 through the hinge 230, and the trigger switch 310 is installed on the side of the movable assembly 200, and the trigger block 320 is installed on the side of the front guard 110; finally, the bolt 111 is installed on the front guard 110, and the positioning bracket 210 is installed on the movable assembly 200, so that the movable assembly 200 is inserted into the positioning bracket 210 through the bolt 111 and fixedly connected with the front guard 110; when the movable assembly 200 is closed on the front guard 110, the movable assembly 200 forms a protective space 140 with the front guard 110, the side guard 120 and the rear guard 130, improving the safety of the staff working on the car top.

[0037] In use, when the elevator is in normal operation, the movable assembly 200 is closed on the front guard 110, the trigger block 320 is attached to the trigger switch 310, and the bolt 111 is inserted into the positioning bracket 210, so as to avoid displacement or even loosening of the trigger block 320 and the trigger switch 310. In practical application, the trigger switch 310 is integrated into the elevator maintenance circuit, and when the trigger switch 310 is pressed, the working circuit of the elevator is turned on, and the elevator can operate normally. At this time, the elevator front guard detection device is in the closed state as shown in Figure 3 When it is necessary to check or maintain the elevator car top, the elevator is in the maintenance position, the bolt 111 is taken out of the positioning bracket 210, and the movable assembly 200 is rotated around the hinge 230, so as to facilitate the staff to enter the protective space 140; since the trigger block 320 no longer abuts against the trigger switch 310, the working circuit of the elevator is turned off, and the elevator cannot operate.
