An upper guide wheel 14 is provided on the inner side of the upper guide rail 13, and a clamping seat 15 is rotatably connected to the lower side of the upper guide wheel 14. A lower guide wheel 17 is provided on the inner side of the lower guide rail 16, and the upper side of the lower guide wheel 17 is rotatably connected to a support seat 18.

[0031] The threaded sleeves 8 are all slidably connected to the metal frame 1, the pressing seat 15 is inserted into the inside of the closed retaining ring 4 on the upper side, and the support seat 18 is inserted into the inside of the closed retaining ring 4 on the lower side. The metal frame 1 is a rectangular frame, and the enamel plate 2 is provided with adjustment holes. The closed retaining ring 4 is composed of a sliding frame and a "U"-shaped plug plate. The inner side of the closed retaining ring 4 is provided with an anti-slip groove, and the closed retaining ring 4 can prevent the pressing seat 15 and the support seat 18 from being dislocated through the anti-slip groove; the two vertical rotating shafts 5 are respectively located above and below the adjustment hole of the enamel plate 2, and the two threaded tubes 7 are respectively located on the left and right sides of the adjustment hole of the enamel plate 2. The threaded tube 7 can drive the two threaded sleeves 8 to approach or move away from each other as the horizontal rotating shaft 6 rotates; the two threaded sleeves 8 are respectively located in the adjustment holes of the enamel plate 2 On the left and right sides of the position, the threaded sleeves 8 are vertically distributed, the transmission rods 9 are tilted, and the transmission seats 10 are horizontally distributed.

[0032] Working process: Before use, install the welding frame 11 under the concrete layer on the top of the building, install the lower guide rail 16 on the building ground, align the lower side of the upper guide rail 13 with the finished surface of the ceiling, and align the upper side of the lower guide rail 16 with the finished surface of the ground, and the device can be used; in the closed state of the device, the distance between the two threaded sleeves 8 is close, and the distance between the two transmission seats 10 is far. At this time, the plug of the closed retaining ring 4 on the upper side is inserted into the closed groove of the upper guide rail 13, and the metal frame 1 and the enamel plate 2 cannot rotate. At the same time, the pressing seat 15 is inserted into the closed groove of the upper guide rail 13. The inside of the closed retaining ring 4 and the support seat 18 are inserted into the inside of the closed retaining ring 4 located on the lower side, and the bottom of the closed retaining ring 4 located on the lower side is in contact with the ground, so the metal frame 1 and the enamel plate 2 can be stably closed and cooperate with the wall to seal the entrance and exit of the civil air defense project.
