When the elliptical locking plate 1202 is rotated to a vertical state, the inner movable plate 1102 is squeezed to allow the elastic plug rod 1103 to be inserted into the socket 13, thereby limiting the rotation of the spare protective door 1101. When the locking plate 1202 is in a horizontal state, the internal spring support of the elastic plug rod 1103 lifts the inner movable plate 1102 to allow the elastic plug rod 1103 to disengage from the socket 13, and at this time the inner movable plate 1102 can be rotated to open.

[0046] When the utility model is in use, firstly, the connecting frame 2 is connected to the top of the car body 1 for easy movement, and the ventilation grille 3 ensures internal air circulation, and then the sliding bar 501 slides left and right on the inner side of the sliding limit frame 4, and the two ends of the sliding bar 501 have limit settings, and the roller 503 at the bottom end rolls left and right inside the movable limit frame 701, the bottom end rolls, and the top end is limited, so that the movement is more convenient, and a buffer baffle 703 is also arranged on the side to connect the extrusion spring 702 for buffering, the internal components of the protective component 2 8 are the same as those of the protective component 1 5, and are symmetrically distributed about the center line of the car body 1, and the rear end of the protective door panel 502 is connected to the rotating card plate 9, which can be rotated, and when the rotating card plate 9 passes through the extrusion arc block 1003, it is stuck on the inner side of the limit frame 1001, and the end of the rotating card plate 9 is limited by the bottom of the limit frame 1001, so that the protective components 1 5 and the protective components 2 8 on both sides will not slide open relative to each other, and only by rotating the rotating card plate 9 back can the rotating card plate 9 be rotated. The protective door 1101 can be moved only when it is separated from the inner side of the limiting frame 1001. At this time, the user can enter and exit. When the movement of the protective component 1 5 and the protective component 2 8 fails and is difficult to open, the spare protective door 1101 is connected to the inner top of the protective door plate 502 by a hinge, and then the inner movable plate 1102 and the elastic plug rod 1103 inside the spare protective door 1101 have a certain space for moving up and down, and the top wall of the inner movable plate 1102 is provided with a groove, which is convenient for the locking plate 1202 to rotate to the vertical position. After being in the straight state, it is stuck in the internal restriction and fixed. When the elliptical locking plate 1202 is rotated to the vertical state, the inner movable plate 1102 is squeezed to allow the elastic plug rod 1103 to be inserted into the socket 13, thereby limiting the rotation of the spare protective door 1101. When the locking plate 1202 is in the horizontal state, the internal spring support of the elastic plug rod 1103 lifts the inner movable plate 1102 to allow the elastic plug rod 1103 to disengage from the socket 13. At this time, the inner movable plate 1102 can be rotated to open for escape.
