A fixing plate 406 is provided below the turntable 401, and the outer surface of the fixing plate 406 is fixedly connected to the outer surface of the U-shaped plate 3. The lower end surface of the fixing plate 406 is provided with a through hole 405, and the outer surface of the through hole 405 is sleeved with a first spring 404, and the insertion rod 403 is adapted to the positioning hole 402, and the insertion rod 403 can be inserted into the inner side of the positioning hole 402.
[0022] The top of the insertion rod 403 is an inclined surface 408, one end of one pin shaft 7 is rotatably connected to the outer surface of the U-shaped plate 3 through a bearing, and the other end of the other pin shaft 7 is fixedly connected to the outer surface of the turntable 401 through a connecting shaft. Vertical plates 2 are installed at the rear of both sides of the outer surface of the U-shaped plate 3, and the outer surface of the vertical plate 2 is provided with threaded holes. When the gas cylinder 1 is rotated clockwise, the top surface of the inclined groove 407 contacts the inclined surface 408, pushing the insertion rod 403 downward. After rotating 90°, the insertion rod 403 is stuck into the inner side of the positioning hole 402 under the action of the first spring 404, fixing the pin shaft 7 and improving the stability of the rotation of the pin shaft 7. The rotation of the pin shaft 7 can drive the turntable 401 to rotate, and the U-shaped plate 3 can be installed through the vertical plate 2.
[0023] Horizontal plates 906 are installed on both sides above the sealing plate 901. The horizontal plates 906 and the sealing plate 901 are movably connected by the third spring 905. Slide grooves 907 are provided on both sides of the inner wall of the fixing ring 902. The inner side of the slide groove 907 is movably connected to a slide plate 908 through a second spring 903. An L-shaped plate 904 is installed on the other side of the outer surface of the slide plate 908. The slide plate 908 can slide on the inner side of the slide groove 907, driving the L-shaped plate 904 to move.
[0024] The outer surface of the fixing ring 902 is fixedly connected to the inner wall of the air inlet 8, the outer surface of the sealing plate 901 is fitted with the inner surface of the fixing ring 902, and the front and rear ends of the slide plate 908 are installed with limiting blocks.

[0026] To sum up, when the check valve body is in use, the check valve body 5 is installed facing the inspection door through the vertical plate 2. When the gas cylinder 1 needs to be replaced, the check valve body 5 is installed facing the inspection door. When the gas cylinder 1 needs to be replaced, the gas cylinder 1 is directly pulled outward, and the gas cylinder 1 is rotated 90° clockwise. At the same time as the gas cylinder 1 rotates, the pin shaft 7 rotates to drive the turntable 401 to rotate, and the top surface of the inclined groove 407 contacts the inclined surface 408, pushing the insertion rod 403 downward to release the limit on the turntable 401. After the turntable 401 rotates 90°, the insertion rod 403 is stuck in the inner side of the positioning hole 402 under the action of the first spring 404, thereby limiting the pin shaft 7 to prevent the pin shaft 7 from rotating when the gas cylinder 1 is replaced.
[0027] By providing a detachable mechanism 11, the two movable plates 1101 are moved in the direction away from the mounting seat 12 at the same time. The movable plate 1101 moves and drives the blocking block 1102 to move. The blocking block 1102 leaves the inner side of the card slot 1103, and the limit of the mounting seat 12 is released. The mounting seat 12 can be removed from the inner side of the mounting slot 10, and the gas cylinder 1 can be replaced. When the mounting seat 12 is removed from the inner side of the mounting slot 10, the air outlet 13 leaves the inner side of the air inlet hole 8, and the slide plate 908 moves downward on the inner side of the slide groove 907 under the action of the second spring 903, driving the L-shaped plate 904 to move downward, and the sealing plate 901 moves downward under the action of the third spring 905, and is stuck in the inner side of the fixing ring 902, sealing the fixing ring 902 to prevent outside air from entering the inner side of the air inlet hole 8.
[0028] Moreover, by providing a filter screen 14, hygiene can be improved, and air that accidentally enters the air inlet 8 can be filtered to prevent the check valve body 5 from being blocked. The utility model facilitates the replacement of the gas cylinder 1, improves efficiency, and when replacing the gas cylinder 1, the air inlet 8 can be automatically sealed to ensure hygiene for subsequent use.
