[0036] In one embodiment of the present invention, a knob-type sealed hatch is provided for opening and closing the electronic disk jack of the chassis. Figure 1-Figure 9 ,include:

[0037] The door 2 is hingedly mounted on the bottom plate 4 on the outer surface of the chassis based on the door fixing screws 7;

[0038] A knob 1 is rotatably mounted on the door 2, with a rotation axis perpendicular to the door 2;

[0039] The locking tongue 5 comprises a fixedly connected snap-fitting part and a protruding part; the hand-held part of the knob 1 protrudes from a side of the door 2 away from the bottom plate 4, the snap-fitting part is nested in the hollow area of ​​the hand-held part, and the protruding part is arranged on a side of the door 2 close to the bottom plate 4;

[0040] A stopper 6 is mounted on the bottom plate 4 and is provided with a slot;

[0041] Wherein: when the knob 1 is rotated, the locking tongue 5 is driven to rotate, and the protrusion enters or leaves the slot, so that the door 2 is locked or opened on the bottom plate 4.

[0042] In this embodiment, the sealed cabin door also includes a limit plate; a rotation groove is provided on the side of the cabin door 2 away from the bottom plate 4; the limit plate is coaxially fixedly installed with the knob 1 and is located in the rotation groove; the limit plate is used to limit the rotation angle of the knob 1.

[0043] In this embodiment, the main body of the rotating groove is a circle coaxial with the rotating shaft, one side of the circular main body is missing, and the edge of the missing part coincides with the edge of the hatch 2; the edge of the limiting piece rotates along the outer ring of the rotating groove; the main body of the limiting piece is annular, and one side of the annular main body is missing;

[0044] When the limiting piece rotates, the two missing ends reach the limiting piece to limit the further rotation of the knob 1.

[0045] In this embodiment, the rotation angle of the knob 1 is 90 degrees, and the rotation angle of the locking tongue 5 is also 90 degrees.

[0046] In this embodiment, a socket is provided on the bottom plate 4 ; the socket is used to enable the electronic disk to enter and exit; the socket is located in the closed space of the cabin door 2 .

[0047] In this embodiment, the door fixing screw 7 is a damping screw.

[0048] In this embodiment, the rotating shaft is a damping rotating shaft.

[0049] In this embodiment, heat dissipation holes are provided on the hatch 2 .

[0050] The stopper 6 of this embodiment is fixed to the bottom plate 4 by screws. The hatch 2 is mounted to the bottom plate 4 by the hatch fixing screws 7, so that the hatch 2 can only realize the circumferential damping rotation along the hatch fixing screws 7. The knob 1 is mounted on the hatch 2 and can realize the damping rotation of the knob 1. The lock tongue 5 is fixed to the knob 1 by the lock tongue stop screw 3, so that the lock tongue 5 and the knob 1 cannot move relative to each other. The rotation of the knob 1 drives the locking and loosening of the lock tongue 5 and the stopper 6, thereby realizing the loosening and sealing locking of the hatch 2 and the bottom plate 4. When the hatch 2 and the bottom plate 4 are loosened, the hatch 2 is opened and closed by pulling the knob 1.
