Then, by rotating the door 4 again, the door 4 rotates, and the outer wall of the locking block 12 can be used to lock the locking buckle 11, realizing the connection between the autoclave body 1 and the door 4.

[0025] In a preferred embodiment: the outer wall of the first cylinder 6 is rotatably connected to the outer wall of the rotating plate 3, and the outer wall of the third cylinder 9 is rotatably connected to the outer wall of the door 4.

[0026] By rotationally connecting the outer wall of the No. 1 cylinder 6 with the outer wall of the rotating plate 3, and the outer wall of the rotating plate 3 with the inner wall of the supporting platform 2, the rotating plate 3 can be rotated from the outer wall of the supporting platform 2 under the action of the No. 1 cylinder 6, and the rotation angle of the rotating plate 3 can be adjusted by controlling the telescopic length of the No. 1 cylinder 6, so that the warehouse door 4 can be opened from the outer wall of the kettle body 1 under the action of the rotating plate 3.

[0027] In a preferred embodiment, a limiting groove is initially formed on the outer wall of the locking buckle 11 , and the shape of the inner wall of the limiting groove matches the shape and size of the outer wall of the locking block 12 .

[0028] By installing the locking buckle 11 on the outer wall of the warehouse door 4, when the warehouse door 4 and the kettle body 1 are installed, the locking block 12 can pass through the limiting groove on the outer wall of the locking buckle 11. At this time, the warehouse door 4 is rotated to make the positions of the locking block 12 and the limiting groove staggered, thereby locking the warehouse door 4 and connecting the warehouse door 4 to the kettle body 1.

[0030] By setting a locking plate 7 on the outer wall of the support platform 2, and the outer wall of the locking plate 7 is in an arc shape, when the rotating plate 3 rotates and opens along the outer wall of the locking plate 7, after the rotating plate 3 is opened to a certain angle, by starting the No. 2 cylinder 8, the outer wall of the No. 2 cylinder 8 enters the limiting hole on the outer wall of the locking plate 7, so that the connection between the rotating plate 3 and the locking plate 7 is realized under the action of the outer wall of the No. 2 cylinder 8, and then the rotating plate 3 is locked.

[0031] In a preferred embodiment: a support plate is installed on the outer wall of the warehouse door 4, and the outer wall of the No. 3 cylinder 9 away from the end of the rotating plate 3 is rotatably connected to the outer wall of the support plate.

[0032] By providing a support plate on the outer wall of the warehouse door 4, when the warehouse door 4 needs to be locked and unlocked, the warehouse door 4 can be driven to rotate under the action of the No. 3 cylinder 9, so that during the rotation of the warehouse door 4, the position of the locking buckle 11 and the outer wall of the locking block 12 are staggered with each other, thereby achieving the locking of the warehouse door 4 and the kettle body 1.

[0033] In a preferred embodiment, the shape and size of the outer wall of the warehouse door 4 matches the shape and size of the outer wall of the kettle body 1, and the outer wall of the limiting frame 10 is in an arc shape.

[0034] By setting a limit frame 10 on the outer wall of the warehouse door 4, and the outer wall of the rotating plate 3 passes through the inner cavity of the limit frame 10, the rotation angle of the warehouse door 4 can be limited under the action of the limit frame 10, so that the warehouse door 4 can be better driven under the action of the No. 3 cylinder 9, so that the outer wall of the locking buckle 11 can be staggered with the position of the locking block 12, thereby realizing the locking of the kettle body 1 and the warehouse door 4.

[0035] In a preferred embodiment: an air pump station is installed on the outer wall of the kettle body 1, and the air pump station is connected to the No. 1 cylinder 6, the No. 2 cylinder 8 and the No. 3 cylinder 9 through pipelines.

[0036] By installing an air pump station on the outer wall of the kettle body 1, air can be supplied to the No. 1 cylinder 6, No. 2 cylinder 8 and No. 3 cylinder 9 under the action of the air pump station, so that the No. 1 cylinder 6, No. 2 cylinder 8 and No. 3 cylinder 9 can make corresponding actions to control the rotation and opening of the warehouse door 4 and the rotating plate 3.

[0037] In a preferred embodiment, the rotating plate 3 , the compartment door 4 and the limiting frame 10 are all made of high carbon steel, and the curvature of the outer wall of the locking plate 7 is the same as the rotation curvature of the outer wall of the rotating plate 3 .

[0038] By setting the No. 2 cylinder 8 on the outer wall of the rotating plate 3, when the rotating plate 3 rotates, the outer wall of the rotating plate 3 rotates around the outer wall of the support platform 2. At this time, the No. 2 cylinder 8 will rotate with the rotation of the rotating plate 3. Since the curvature of the outer wall of the locking plate 7 is the same as the rotation curvature of the rotating plate 3, the No. 2 cylinder 8 can smoothly enter the limiting hole opened on the outer wall of the locking plate 7, thereby locking the rotating plate 3.

[0039] Working principle: During the use of the above-mentioned equipment, when it is necessary to open the warehouse door 4 from the outer wall of the kettle body 1, the No. 3 cylinder 9 is started, and the warehouse door 4 is pushed to rotate under the action of the No. 3 cylinder 9. As the warehouse door 4 rotates, the locking buckle 11 will also rotate, so that the outer wall of the locking block 12 corresponds to the limiting groove on the outer wall of the locking buckle 11, and the warehouse door 4 can be unlocked at this time. Subsequently, the No. 1 cylinder 6 is started, and the rotation of the rotating plate 3 is driven by the action of the No. 1 cylinder 6, so that the outer wall of the warehouse door 4 can be separated from the outer wall of the kettle body 1 under the action of the rotation of the rotating plate 3, and the warehouse door 4 can be opened. After the rotating plate 3 is rotated, the No. 2 cylinder 8 is started, so that the outer wall of the No. 2 cylinder 8 enters the limiting hole in the inner cavity of the locking plate 7, thereby locking the rotating plate 3, so that the outer wall of the rotating plate 3 is fixed between the locking plate 7 under the action of the No. 2 cylinder 8, thereby ensuring the stability of the rotating plate 3, and then the warehouse door 4 can be better opened.
