[0036] See Figures 1-9 As shown, this embodiment discloses a sealed door, which includes:

[0037] A door panel 1, one side of the door panel 1 is an installation surface 11, and the two side edges of the installation surface 11 perpendicular to each other are the first direction and the second direction;

[0038] A movable plate 2, slidably connected to the door panel 1, and the sliding direction is the same as or opposite to the first direction; the movable plate 2 is provided with an inclined groove 21 along the first direction, and the groove depth direction of the inclined groove 21 is the same as or opposite to the second direction;

[0039] A sealing plate 3, arranged parallel to the installation surface 11 and slidably connected to the door panel 1; the inclined groove 21 extends from the door panel 1 towards the sealing plate 3 and is gradually inclined; the sliding direction of the sealing plate 3 is perpendicular to the installation surface 11; the sealing plate 3 is provided with rollers 31 corresponding to the inclined groove 21, and the rollers 31 are inserted into the inclined groove 21;

[0040] The telescopic driving member 4 is connected to the door panel 1 and is arranged along the first direction, and is used to drive the movable plate 2 to slide, so that the inclined groove 21 pushes the roller 31 to move in a direction perpendicular to the mounting surface 11, and further makes the sealing plate 3 move away from or close to the door panel 1.

[0041] When the telescopic driving member 4 drives the movable plate 2 to move along the first direction, the inclined groove 21 moves along with the movable plate 2, and the inner wall of the inclined groove 21 abuts against the roller 31, so that the roller 31 receives an oblique supporting force and a frictional force. The oblique supporting force and the frictional force enable the roller 31 to receive a supporting force perpendicular to the mounting surface 11. Therefore, the roller 31 moves in a direction perpendicular to the mounting surface 11. The roller 31 is mounted on the sealing plate 3, and the sealing plate 3 moves along with the roller 31 to approach or move away from the door panel 1.

[0042] In this embodiment, the sealing plate 3 is slidably connected to the door panel 1 to approach the sealing frame 9, realizing the close fit between the sealing door and the sealing frame 9 without affecting the structural stability of the door panel 1; by driving the roller 31 to move in a direction perpendicular to the mounting surface 11 through the telescopic driving member 4 and the movable plate 2, and further making the sealing plate 3 move away from or close to the door panel 1, the movement of the sealing plate 3 is realized, which is beneficial to the fit between the sealing plate 3 and the sealing frame 9 to achieve a preset sealing effect.

[0043] In actual application, when the sealing frame 9 is vertically arranged, the sealing door is vertically arranged, and the first direction can be the vertical direction or the horizontal direction; when the sealing frame 9 is horizontally arranged, the sealing door is horizontally arranged, and the first direction can be the vertical direction or the horizontal direction. This embodiment is described in the case where the sealing door is vertically arranged and the first direction is the vertical direction. Specifically, the door panel 1, the movable plate 2 and the sealing plate 3 are all vertically arranged. The telescopic driving member 4 drives the movable plate 2 to lift and lower, the inclined groove 21 drives the roller 31 to move horizontally, and the roller 31 drives the sealing plate 3 to move horizontally to embed in or move away from the sealing frame 9, realizing the sealing or unsealing of the cavity.

[0044] In one embodiment, the door panel 1 and the sealing plate 3 are overlapped and are both square plates. The overlapping of the sealing plate 3 and the door panel 1 makes the overall occupied area of the sealing door smaller, facilitating the flexible installation of the sealing door, making the sealing door applicable to areas with limited space, and improving the practicability of the sealing door.

[0045] In one embodiment, the movable plate 2 is slidably connected to one side of the door panel 1 perpendicular to the mounting surface 11; a guide rail 12 is provided on one side of the door panel 1 perpendicular to the mounting surface 11, and a slider 22 is provided on the movable plate 2, and the slider 22 is slidably connected to the guide rail 12; a roller 31 is provided on one side of the sealing plate 3 perpendicular to the mounting surface 11. The cooperation of the slider 22 and the guide rail 12 facilitates the smooth sliding of the movable plate 2 relative to the door panel 1; the movable door is provided on one side of the door panel 1, so that when the sealing door does not perform the sealing work, the distance between the sealing plate 3 and the door panel 1 is small, reducing the thickness of the sealing door, making the structure of the sealing door more compact and stable, and at the same time facilitating the movement of the sealing door.

[0046] In one embodiment, the number of the movable plates 2 is two, and the two movable plates 2 are symmetrically arranged on both sides of the door panel 1 respectively; at least one inclined groove 21 is provided on the movable plate 2; rollers 31 corresponding to the inclined grooves 21 are provided on both sides of the sealing plate 3. The movable plates 2 located on both sides of the door panel 1 act together on the sealing plate 3, making the movement of the sealing plate 3 more balanced and stable, and facilitating the sealing plate 3 to be horizontal with the sealing frame 9 during the process of entering the sealing frame 9, so that all four sides of the sealing plate 3 can be attached to the sealing frame 9. In this embodiment, three inclined grooves 21 are provided on the movable plate 2, and three rollers 31 are provided on the corresponding sealing plate 3. The two movable plates 2 are symmetrically arranged, so that the supporting forces on both sides of the sealing plate 3 are evenly distributed, increasing the stability and balance of the structure of the sealing plate 3, reducing the maintenance times of the sealing door. If one of the rollers 31 falls off or the structure of the inclined groove 21 is damaged, it does not affect the normal operation of the sealing plate 3, improving the reliability of the sealing door.

[0047] In one embodiment, the roller 31 is connected to the sealing plate 3 through a convex shaft 32. One end of the convex shaft 32 is connected to the sealing plate 3. The other end passes through the roller 31. The rolling of the roller 31 reduces the force required for the inclined groove 21 to push the sealing plate 3, contributing to the rapid sliding of the sealing plate 3.

[0048] In one embodiment, the inclined groove 21 includes a square groove 211 and two semi-circular grooves 212. The two semi-circular grooves 212 are provided at both ends of the square groove 211, and the semi-circular grooves 212 communicate with the square groove. The semi-circular grooves 212 and the square groove 211 enclose an oval shape, and the diameter of the semi-circular groove 212 is slightly larger than the diameter of the roller 31. In the initial state, the roller 31 is located in one of the semi-circular grooves 212. When the movable plate 2 moves, the roller 31 is pushed by the square groove 211 and gradually moves into the other semi-circular groove 212. The square groove 211 is used to provide a supporting force for the roller 31 and also provide a guiding function for the roller 31; the semi-circular groove 212 has a certain arc, providing a supporting force for the roller 31 to enter the square groove 211, and making the stress distribution of the inclined groove 21 uniform and not easily damaged, improving the structural stability of the sealing door.

[0049] In one embodiment, the door panel 1 is provided with a shaft hole 13, and the shaft hole 13 is arranged perpendicular to the mounting surface 11; the sealing plate 3 is provided with a connecting shaft 33, and the connecting shaft 33 passes through the shaft hole 13; a limiting portion 331 is provided at one end of the connecting shaft 33 away from the sealing plate 3, and the shaft hole 13 is located between the limiting portion 331 and the sealing plate 3. Specifically, the length of the connecting shaft 33 is greater than the length of the shaft hole 13. The sealing plate 3 is slidably connected to the door panel 1 through the connecting shaft 33 and the shaft hole 13, and the limiting portion 331 is used to prevent the sealing plate 3 from detaching from the door panel 1. During the process of the sealing plate 3 moving away from the door panel 1, the limiting portion 331 gradually approaches the door panel 1, and during the process of the sealing plate 3 approaching the door panel 1, the limiting portion 331 gradually moves away from the door panel 1.

[0050] In one embodiment, the telescopic driving member 4 is a telescopic cylinder. In other embodiments, the telescopic driving member 4 can be replaced with driving members such as an electric cylinder, a linear motor, or a hydraulic cylinder instead of the telescopic cylinder.

[0051] In one embodiment, the door panel 1 is provided with a mounting cavity 14, and the telescopic driving member 4 is arranged in the mounting cavity 14. The telescopic driving member 4 does not need to be exposed outside the door panel 1, so that the occupied area of the sealing door is reduced.

[0052] In one embodiment, the sealing door of this embodiment further includes: a driving plate 5 and a connecting plate 6; the driving plate 5 and the connecting plate 6 are arranged along the second direction; the driving plate 5 is arranged in the mounting cavity 14 and fixedly connected to the output shaft of the telescopic driving member 4; the connecting plate 6 is fixedly connected to the driving plate 5 and the movable plate 2. The telescopic driving member 4 drives the driving plate 5 to move along the first direction, the driving plate 5 drives the connecting plate 6 to move along the first direction, and the connecting plate 6 drives the movable plate 2 to move along the first direction.

[0053] In one embodiment, the connecting plate 6 is arranged on the side of the door panel 1 away from the mounting surface 11. The connecting plate 6 is arranged away from the sealing plate 3, preventing it from affecting the movement of the sealing plate 3, and reducing the structure between the sealing plate 3 and the door panel 1, so that the sealing plate 3 can closely adhere to the door panel 1 when approaching the door panel 1, greatly reducing the thickness of the sealing door and saving the occupied space of the sealing door, which is beneficial for the operator to perform loading and unloading operations on the cavity.

[0054] In one embodiment, a protective cover 7 is provided on the side of the door panel 1 away from the mounting surface 11, and the connecting plate 6 is located between the door panel 1 and the protective cover 7; heat dissipation holes are provided on the protective cover 7. The protective cover 7 is used to prevent dust from entering the mounting cavity 14 and accumulating on the surface of the telescopic driving member 4, and the heat dissipation holes can avoid heat accumulation when the telescopic driving member 4 operates, ensuring the service life of the telescopic driving member 4 and improving the reliability of the sealing door.

[0055] In one embodiment, the sealing door of this embodiment further includes: a door closing mechanism 8; the door panel 1 is connected to the door closing mechanism 8, and the door closing mechanism 8 is used to drive the door panel 1 to move to be exactly corresponding to the specified sealing frame 9. The door closing mechanism 8 can be a translation mechanism for driving the door panel 1 to translate, or an articulated mechanism for driving the door panel 1 to rotate. In this embodiment, the door closing mechanism 8 is a translation mechanism.

[0056] In one embodiment, the door closing mechanism 8 includes: a translation driving member 81 and two fixing plates 82; the two fixing plates 82 are symmetrically arranged, the fixing plates 82 extend along the second direction, and the fixing plates 82 are used for fixedly connecting with the specified sealing frame 9; both ends of the door panel 1 in the first direction are slidably connected to the two fixing plates 82 respectively; the translation driving member 81 is used to drive the door panel 1 to move along the fixing plates 82. The connection of both ends of the door panel 1 to the fixing plates 82 ensures the perpendicularity and balance of the door panel 1 and the sealing effect of the sealing plate 3.

[0057] In one embodiment, the translation driving member 81 includes: a driving motor 811, two chain belt groups 812 and a synchronizing rod.
