The upper and lower parts of the rotating shaft 22 are both installed with slewing bearings 24. The rotating shaft 22 is installed on the bearing seats 12 at the upper and lower ends of the pillar 11 through the upper and lower slewing bearings 24. The bottom end of the rotating shaft 22 is rotatably installed on the door body support frame 6 through the pressure bearing 25.

[0030] The upper part of the rotating shaft 22 passes through the upper end of the chamber body 7, and a connecting rod mechanism 3 is installed on the top of the rotating shaft 22 through a rocker rod 23. The cylinder assembly 4 and the guide assembly 5 are both installed on the top end outside the chamber body 7. The connecting rod mechanism 3 is installed on the guide assembly 5. The cylinder assembly 4 drives the guide assembly 5 to drive the connecting rod mechanism 3 to move, and the connecting rod mechanism 3 drives the two door panels 21 to open or close synchronously.

[0031] The connecting rod mechanism 3 includes a push rod 31 and connecting rods 32 hinged on both sides of the push rod 31 . The connecting rods 32 on both sides of the push rod 31 are hingedly connected to the rocker 23 , and the other end of the rocker 23 is fixed to the top of the rotating shaft 22 .

[0032] The guide assembly 5 includes a guide shaft 51, a guide slider 52 and a guide shaft fixing seat 53. The guide shaft fixing seat 53 is installed at the top end outside the chamber body 7 and is placed at the front end of the cylinder assembly 4. The guide slider 52 is slidably installed on the guide shaft 51 and is installed on the guide shaft fixing seat 53. The connecting rod mechanism 3 is installed on the guide slider 52.

[0033] The two door panels 21 rotate horizontally 90 degrees along the rotation axis 22. When the two door panels 21 are in the open state, the two door panels 21 are parallel to each other; when the two door panels 21 are in the closed state, the two door panels 21 are in the same plane.

The rotating shaft 22 is installed on the bearing seats 12 at the upper and lower ends of the pillars 11 through the upper and lower slewing bearings 24, and the bottom end of the rotating shaft 22 is rotatably installed on the door support frame 6 through a pressure bearing 25; the upper part of the rotating shaft 22 passes through the upper end of the room body 7, and the top of the rotating shaft 22 is installed with a connecting rod mechanism 3 through a rocker rod 23, which guides The guide shaft fixing seat 53 of the component 5 is installed at the top outside the chamber body 7, the cylinder component 4 is installed at the rear end of the guide component 5, the guide slider 52 is slidably installed on the guide shaft 51, and is installed on the guide shaft fixing seat 53, and the push rod 31 of the connecting rod mechanism 3 is installed on the guide slider 52; the guide shaft 51 of the guide component 5 is parallel to the extension and contraction direction of the cylinder, and the extension and contraction of the cylinder of the cylinder component 4 pushes the push rod 31 of the connecting rod mechanism 3 to move on the slider, thereby driving the two door panels 21 to rotate along the rotating shaft 22, thereby realizing the synchronous opening or closing of the two door panels 21, and the two door panels 21 rotate horizontally 90° along the rotating shaft 22. When the two door panels 21 are in the open state, the two door panels 21 are parallel to each other; when the two door panels 21 are in the closed state, the two door panels 21 are in the same plane.

[0037] Pneumatic rotary double door open state: the cylinder push rod 31 extends, pushing the push rod 31 of the connecting rod mechanism 3 to move forward along the guide shaft 51, and the push rod 31 drives the rotating shaft 22 welded by the rocker arm 23 to rotate through the hinged connecting rod 32, so that the two door panels 21 are opened.

[0038] Pneumatic rotary double door closed state: the cylinder push rod 31 retracts, pushing the push rod 31 of the connecting rod mechanism 3 to move backward along the guide shaft 51, and the push rod 31 drives the rotating shaft 22 welded by the rocker arm 23 to rotate in the opposite direction through the hinged connecting rod 32, so that the two door panels 21 are closed.
