A rotatable box door 6 is arranged on the door frame 5, and a touch controller 25 is arranged on the outer wall of the box door 6. The door frame 5 includes four frames arranged around the box opening 4.

[0028] Combination Figure 3 and Figure 6 As shown, each frame is provided with a first sealing groove 7 along its own length direction, and the box door 6 is provided with four sealing parts 8 around its own circumference, each sealing part 8 extends along the length direction of one side of the box door 6, and the four sealing parts 8 correspond to the four first sealing grooves 7 one by one, and each sealing part 8 can be embedded in the corresponding first sealing groove 7.

[0029] When the box door 6 is closed on the door frame 5, the four sealing parts 8 can be embedded in the four first sealing grooves 7 one by one, thereby eliminating the gap between the box door 6 and the door frame 5, effectively improving the sealing between the box door 6 and the box body 1, and improving the test accuracy of the test product in the box body 1.

[0030] In this embodiment, mounting grooves 10 are respectively opened on the groove walls on both sides of the first sealing groove 7, and the mounting grooves 10 extend along the length direction of the first sealing groove 7.

When the second sealing block 12 is accommodated in the sealing cavity 13, the ends of the two first sealing blocks 9 can be respectively inserted into the two second sealing grooves 17 and conflict with the sealing strip 18. In this way, the gap between the first sealing block 9 and the sealing portion 8 can be eliminated, and the sealing between the box door 6 and the box body 1 is further improved.

[0037] The second sealing groove 17 is V-shaped, and has a first groove wall that is aligned with the conical surface of the second cone portion, and a second groove wall that is away from the second cone portion, and the second groove wall is parallel to the first inclined surface. After the first sealing block 9 is inserted into the second sealing groove 17, it can be matched and engaged with the second sealing groove 17, further improving the sealing between the box door 6 and the box body 1.

The outer door 61 can achieve effective sealing through the cooperation of the sealing portion 8 and the first sealing groove 7, and the inner door 62 can cooperate with the outer door 61 to form a double protection for the box body 1, further improving the sealing between the box door 6 and the box body 1; at the same time, the staff can directly observe the conditions in the box body 1 through the transparent inner door 62, without frequently opening the inner door 62, effectively avoiding the environmental parameters in the box body 1 from changing due to multiple door openings.

[0039] Combine again Figure 3 and Figure 6As shown, the upper and lower sides of the outer frame 51 respectively have two first outer frames, and the left and right sides respectively have two second outer frames. The two first outer frames are respectively provided with fasteners 19 on one side facing the inner door 62. The two ends of the fasteners 19 are respectively hinged with the two second outer frames.

The second fastening plate 193 can be against the inner door 62 when the inner door 62 is closed, effectively improving the sealing between the inner door 62 and the box body 1; and the first fastening plate 192 and the second fastening plate 193 can be flipped synchronously during the opening and closing process of the inner door 62, avoiding the first fastening plate 192 and the second fastening plate 193 from affecting the opening and closing of the inner door 62.

[0040] Specifically, when closing the inner door 62, the inner door 62 pushes the first fastening plate 192 during the rotation process, so that the first fastening plate 192 and the second fastening plate 193 flip synchronously, and when the inner door 62 is completely closed, the first fastening plate 192 abuts against the first outer frame, and the second fastening plate 193 abuts against the outer wall of the inner door 62; when opening the inner door 62, the inner door 62 pushes the second fastening plate 193 during the rotation process, so that the second fastening plate 193 and the first fastening plate 192 flip synchronously, and when the inner door 62 is completely opened, the second fastening plate 193 abuts against the first outer frame.
