[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a clean door with strong sealing performance, including a support door frame 8 for support, an alignment slot 1 for limiting is provided at the inner end face of the support door frame 8 near the side.

[0024] A sealing ring 6, the sealing ring 6 is fixedly arranged on the inner end face of the alignment slot 1, and a servo motor 5 is arranged at the upper end face of the support door frame 8 near the alignment slot 1, and a ball screw 7 is fixedly arranged at the output end of the servo motor 5;

[0025] A support device 2, the support device 2 is slidably clamped on the inner end face of the alignment slot 1;

[0026] A closing device 3, there are two groups of closing devices 3 in total, and both groups of closing devices 3 are arranged at the rear end face of the support device 2. A ball slide 4 is fixedly arranged at the upper end face of the upper closing device 3, and the ball slide 4 is threadedly connected with the ball screw 7.

[0027] The support device 2 includes a clean door housing 22, an alignment chamfer 23 for alignment is provided on the outer end face of the clean door housing 22, and two groups of connecting card plates 21 are symmetrically arranged on the inner end face of the clean door housing 22.

[0028] The closing device 3 includes a guiding slide 31, two groups of cylinder housings 33 for guiding are arranged at the rear end face of the guiding slide 31, and a cylinder push rod 32 is slidably clamped on the inner end face of the cylinder housing 33.

[0029] Both groups of guiding slides 31 are slidably clamped inside the support door frame 8, which can effectively improve the stability of the displacement of the closing device 3 at the upper part of the support door frame 8.

[0030] The clean door housing 22 is press-fitted and sealed with the inside of the sealing collar 6 through the alignment chamfer 23. The sealing collar 6 can be press-fitted onto the outside of the clean door housing 22, thereby improving the sealing performance after the clean door housing 22 is closed.

[0031] The cylinder push rod 32 is fixedly connected to the connecting clamping plate 21, which can facilitate the subsequent four groups of cylinder housings 33 to quickly guide the clean door housing 22 through the cylinder push rod 32, and improve the stability of the subsequent opening and closing of the clean door housing 22.
