After the sliding rod 213 slides into the through groove 31, the moving plate 3 is limited to rotate, so that the moving plate 3 and the positioning plate 2 are mutually perpendicular to each other, the positioning cavity 22 is blocked, and the civil air defense door is fixed on the base 1.

Referring to fig. 2 and 3, a fixing piece 215 is fixed on the bottom wall of one end of the connecting rod 212 sliding into the sliding rod 213, a fixing groove 216 for sliding the fixing piece 215 along the vertical direction is formed in the sliding rod 213, and the fixing groove 216 is communicated with the groove 214. The fixing piece 215 is slidably abutted against the wall of the fixing groove 216 to limit the fixing rod 211 from sliding out of the connecting rod 212. The situation that the fixing rod 211 is separated from the connecting rod 212 is reduced, and the stability of the movable plate 3 during fixing is improved.

Referring to fig. 4, a connecting shaft 12 slides in the base 1 along the horizontal direction, and one end of the moving plate 3, which is close to the base 1, is rotatably sleeved on the connecting shaft 12 to form a hinge. A storage groove 13 for the movable plate 3 to slide horizontally is formed in the base 1, and the storage groove 13 is used for the connecting shaft 12 to slide. The moving plate 3 is slid into the receiving groove 13 so as to receive the moving plate 3.

Referring to fig. 1 and 4, an opening 14 for the moving plate 3 to rotate upwards is formed in the groove wall of the storage groove 13, so that the moving plate 3 can be rotated to a position parallel to the civil air defense door, one side of the positioning cavity 22 is blocked, and the periphery of the civil air defense door is blocked, so that the civil air defense door is fixed, and the civil air defense door is prevented from shaking on the base 1.

Referring to fig. 4, a chute 15 for horizontally sliding both ends of the connection shaft 12 is provided in the base 1, and the chute 15 is communicated with the receiving groove 13. The connecting shaft 12 is in sliding contact with the wall of the chute 15, so as to limit the connecting shaft 12 from sliding out of the base 1, and further limit the moving plate 3 from being separated from the base 1.

Referring to fig. 4, a slant surface 16 for the moving plate 3 to rotate downward is provided on a sidewall of the base 1, and the slant surface 16 is connected with a groove wall of the receiving groove 13. The upper end of the moving plate 3 is abutted with the inclined surface 16, the lower end is abutted on the ground, and the civil air defense door is slid upwards into the positioning cavity 22 along the moving plate 3 so as to move the civil air defense door conveniently.

Referring to fig. 4 and 5, a plurality of limiting frames 17 are fixed on the bottom wall of the base 1, limiting rods 18 slide in the limiting frames 17 along the horizontal direction, and two limiting frames 17 are selected in the embodiment of the application. The bottom wall of the movable plate 3 is provided with a limit groove 32 into which the limit rod 18 slides, and the limit rod 18 is clamped in the limit groove 32 by friction force to limit the rotation of the movable plate 3 and fix the limit plate on the inclined plane 16.

Referring to fig. 1 and 6, the lifting assembly 11 includes a first rod 111 fixed on the bottom wall of the base 1, a second rod 112 sliding in the first rod 111 along the vertical direction, and a bolt 113 penetrating through and screwed on the first rod 111, wherein the second rod 112 is provided with a plurality of screw grooves 115 for the threaded connection of the bolt 113, and one end of the second rod 112 far from the first rod 111 is rotatably connected with a roller 114. The height of the base 1 is adjusted by sliding the second rod 112 in or out of the first rod 111, thereby facilitating the positioning of the height of the civil air defense door. Because the civil air defense door is heavier, the height of the base 1 is adjusted before the civil air defense door is placed, and then the civil air defense door is placed, so that the situation that the civil air defense door is overweight and the height of the base 1 is inconvenient to adjust is avoided.

The implementation principle of the civil air defense door positioning structure in the embodiment of the application is as follows: when the civil air defense door is positioned, the height of the civil air defense door mounted on the door frame is measured firstly, and then the second rod 112 slides into or out of the first rod 111 according to the measured height, so that the height of the base 1 is adjusted, and the height of the civil air defense door on the base 1 is the same as the height of the civil air defense door mounted on the door frame. Then, the slide bar 213 is slid upward out of the through groove 31, and the slide bar 213 is released from the fixation of the moving plate 3. The moving plate 3 is rotated downwards, so that the limiting rod 18 slides into the limiting groove 32, and the upper end of the moving plate 3 is abutted against the inclined surface 16, and the lower end is abutted against the ground. And then the limiting rod 18 slides into the limiting groove 32 along the horizontal direction, and the moving plate 3 is fixed on the inclined surface 16. The civil air defense door is placed on the moving plate 3, and is pushed upwards into the positioning cavity 22 along the moving plate 3.
