Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following is combined with Figure 1-6 To further explain this application in detail,

[0026] The embodiment of the present application discloses a baffle mechanism in a vacuum environment, comprising a sealing chamber 10, a fixed frame 7 is fixedly connected to the opening at the front of the sealing chamber 10, a cylinder 1 is fixedly connected to the hole starting from the middle of the fixed frame 7, a push rod 2 is rotatably connected to the end of the cylinder 1, a rotating shaft 3 is fixedly connected to the end of the push rod 2, a push plate 4 is rotatably connected to the end of the rotating shaft 3, one end of the push plate 4 is fixedly connected to the rear of the fixed frame 7, the other end of the push plate 4 is fixedly connected to the baffle 6, the end of the baffle 6 is slidably connected to the guide seat 5, and the end of the guide seat 5 is fixedly connected to the side of the fixed frame 7;

[0027] The push rod 2 further includes a connecting handle 21, the outer wall of the push rod 2 is fixedly connected to one end of the connecting handle 21, and the other end of the connecting handle 21 is rotatably connected to the end of the cylinder 1;

[0028] The push plate 4 includes a hinge seat 41 and a hinge plate 42. One end of the push plate 4 is rotatably connected to the end of the hinge seat 41. The base of the hinge seat 41 is fixedly connected to the rear of the fixed frame 7. The other end of the push plate 4 is rotatably connected to the end of the hinge plate 42. The base of the hinge plate 42 is fixedly connected to the end surface of the baffle 6.

[0029] The hinge plate 42 further comprises a hinge handle 421, the middle portion of the hinge plate 42 is fixedly connected to the end of the hinge handle 421, and the rotating column of the hinge handle 421 is rotatably connected to the end of the push plate 4;

[0030] The block of the guide seat 5 is provided with a sliding groove 51, and the sliding groove 51 is slidably connected to the end of the baffle 6;

[0031] The end of the baffle 6 is fixedly connected with a sliding member 61, and the column of the sliding member 61 is slidably connected to the sliding groove 51;

[0032] The fixing frame 7 further includes a flange 71 , and the rear portion of the fixing frame 7 is fixedly connected with the flange 71 .

[0033] Working principle: when in use, the cylinder 1 needs to be started to move, the cylinder 1 will extend, and the end of the cylinder 1 will push the connecting handle 21. Because the connecting handle 21 is in an inclined state, when the connecting handle 21 is subjected to thrust, the connecting handle 21 drives the rotating shaft 3 to move through the push rod 2. The end of the rotating shaft 3 is the triangular part of the rotating connecting push plate 4, so the rotating shaft 3 will push the push plate 4 to rotate. The connection part between the two push plates 4 and the hinge handle 421 is arc-shaped, so the push plate 4 will push the hinge handle 421 to slide horizontally during the rotation process, and the two hinge handles 421 will drive the baffle 6 to move synchronously through the hinge plate 42. The sliding member 61 arranged at the end of the baffle 6 is slidably connected to the sliding groove 51. The sliding member 61 will slide under the restriction of the sliding groove 51, so that the sliding of the baffle 6 is more stable. When the baffle 6 slides into place, the baffle 6 will seal the ventilation channel in the middle of the flange 71. At this time, the atmospheric side in the front of the fixed frame 7 and the vacuum environment in the rear of the fixed frame 7 are isolated. When the channel between the two sides needs to be opened, the cylinder 1 needs to be contracted. The cylinder 1 will drive the rotating shaft 3 to reset through the push rod 2, and the rotating shaft 3 will drive the push plate 4 to reset, and the push plate 4 will drive the baffle 6 to reset. At this time, the atmospheric side and the vacuum side can communicate with each other.

[0034] The sliding of the baffle 6 is controlled by the extension and retraction of the cylinder 1, so that the vacuum environment inside the sealed chamber 10 is connected with the external atmospheric environment. Through the above structure, the opening process can be made smoother, avoiding the mismatch between accessories when using other tools, resulting in damage to parts, and uneven force in the opening process, and sudden force causing parts to loosen and be damaged; and one end of the push plate 4 is a triangular part and the other end is an arc part, so that when the push plate 4 rotates, the push plate 4 can stably push the baffle 6 to slide, avoiding the occurrence of jamming and unsmoothness between the two components.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
