[0039] Embodiment 1

[0040] See Figures 1-9 As shown, this embodiment discloses a sealing door, which includes:

[0041] Door panel 1, one side of the door panel 1 is the mounting surface 11, and the two side edges of the mounting surface 11 perpendicular to each other are the first direction and the second direction;

[0042] 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; the inclined groove 21 extends from the door panel 1 towards the sealing plate 3 and is gradually inclined;

[0043] Sealing plate 3, arranged parallel to the mounting surface 11 and slidably connected to the door panel 1; the sliding direction of the sealing plate 3 is perpendicular to the mounting 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; when the movable plate 2 moves along the first direction, the inclined groove 21 pushes the rollers 31 to move in a direction perpendicular to the mounting surface 11, so that the sealing plate 3 moves away from or close to the door panel 1;

[0044] Door closing assembly 8, connected to the door panel 1, and the door closing assembly 8 is used to drive the door panel 1 to move to be directly corresponding to or away from the specified sealing frame 9.

[0045] In this embodiment, the door closing assembly 8 can be a translation assembly for driving the door panel 1 to translate or a hinge assembly for driving the door panel 1 to rotate; when the door closing assembly 8 drives the door panel 1 to be directly corresponding to the specified sealing frame, move the movable plate 2 so that the inclined groove 21 follows the movable plate 2 to move along the first direction, and the inner wall of the inclined groove 21 abuts against the rollers 31, so that the rollers 31 receive an oblique supporting force and frictional force, and the oblique supporting force and frictional force cause the rollers 31 to receive a supporting force perpendicular to the mounting surface 11. Therefore, the rollers 31 move in a direction perpendicular to the mounting surface 11, and the rollers 31 are installed on the sealing plate 3, and the sealing plate 3 moves with the rollers 31 to move away from or close to the door panel 1.

[0046] In this embodiment, the sealing plate 3 is slidably connected to the door panel 1 to be close to the sealing frame 9, realizing the close fit of the sealed door and the sealing frame 9 without affecting the structural stability of the door panel 1; by manually or electrically moving the movable plate 2, the movable plate 2 drives the rollers 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, realizing the movement of the sealing plate 3, which is beneficial to the fit of the sealing plate 3 and the sealing frame 9 to achieve a preset sealing effect; by overlapping the sealing plate 3 and the door panel 1, the overall occupied area of the sealed door is smaller, facilitating the flexible installation of the sealed door, making the sealed door suitable for areas with limited space, and improving the practicability of the sealed door.

[0047] 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. In this embodiment, the case where the sealing door is vertically arranged and the first direction is the vertical direction is described. 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 move up and down, and the inclined groove 21 drives the roller 31 to move horizontally. The roller 31 drives the sealing plate 3 to move horizontally to be inserted into or away from the sealing frame 9, so as to seal or unseal the cavity.

[0048] Specifically, both the door panel 1 and the sealing plate 3 are square plates; the movable plate 2 is slidably connected to one side of the door panel 1 perpendicular to the installation surface 11; a guide rail 12 is provided on one side of the door panel 1 perpendicular to the installation surface 11, and the movable plate 2 is provided with a slider 22, and the slider 22 is slidably connected to the guide rail 12; the roller 31 is arranged on one side of the sealing plate 3 perpendicular to the installation 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 arranged 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.

[0049] Specifically, 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 arranged on the movable plate 2; rollers 31 corresponding to the inclined grooves 21 are arranged 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 around of the sealing plate 3 can be attached to the sealing frame 9. In this embodiment, three inclined grooves 21 are arranged on the movable plate 2, and three rollers 31 are arranged 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.

[0050] Specifically, 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, and 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, which helps the sealing plate 3 to slide quickly.

[0051] Specifically, 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 groove 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 provides a guiding function for the roller 31. The semi-circular groove 212 has a certain curvature, which provides a supporting force for the roller 31 to enter the square groove 211, and makes the stress distribution of the inclined groove 21 uniform, not easily damaged, and improves the structural stability of the sealing door.

[0052] Specifically, 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. When the sealing plate 3 moves away from the door panel 1, the limiting portion 331 gradually approaches the door panel 1. When the sealing plate 3 approaches the door panel 1, the limiting portion 331 gradually moves away from the door panel 1.

[0053] Specifically, the sealing door of this embodiment further includes a telescopic driving member 4. The telescopic driving member 4 is connected to the door panel 1 and is used to drive the movable plate 2 to move along the first direction. The telescopic driving member 4 is arranged along the first direction 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, thereby moving the sealing plate 3 away from or close to the door panel 1.

[0054] Specifically, the telescopic driving member 4 is a telescopic cylinder. In other embodiments, the telescopic driving member 4 can be replaced by a driving member such as an electric cylinder, a linear motor, or a hydraulic cylinder instead of the telescopic cylinder.

[0055] Specifically, the door panel 1 is provided with an installation cavity 14, and the telescopic driving member 4 is arranged in the installation 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.

[0056] Specifically, 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 installation 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. Both ends of the connecting plate 6 are connected to the two movable plates 2, so that the two movable plates 2 can move synchronously.

[0057] Specifically, the connecting plate 6 is arranged on the side of the door panel 1 away from the installation surface 11. The connecting plate 6 is arranged away from the sealing plate 3 to prevent affecting the movement of the sealing plate 3, and reduces 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 load and unload the cavity.

[0058] Specifically, a protective cover 7 is provided on the side of the door panel 1 away from the installation surface 11; 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 installation 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.

[0059] Specifically, the door closing assembly 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 a specified sealing frame 9; both ends of the door panel 1 in the first direction are respectively slidably connected to the two fixing plates 82; the translation driving member 81 is used to drive the door panel 1 to move along the fixing plates 82. In this embodiment, the door closing assembly 8 is a translation assembly. When the sealing needs to be released, the sealing plate 3 approaches the door panel 1, and the door panel 1 is driven by the translation driving member 81 to translate along the fixing plates 82 to move away from the sealing frame 9. Both ends of the door panel 1 are connected to the fixing plates 82, ensuring the perpendicularity and balance of the door panel 1 and the sealing effect of the sealing plate 3.

[0060] Specifically, the translation driving member 81 includes: a driving motor 811, two chain belt groups 812 and a synchronizing rod. The two chain belt groups 812 are respectively rotatably connected to the two fixing plates 82. The driving motor 811 drives the chain belt groups 812 to rotate, and the synchronizing rod connects the two chain belt groups 812. The chain belt group 812 includes: a driving wheel, a driven wheel and a chain belt. The driving wheel and the driven wheel are rotatably connected to the fixing plate 82. The chain belt is sleeved and drivingly connected to the driving wheel and the driven wheel. The chain belt is arranged along the second direction, and the door panel 1 is fixedly connected to the chain belt. Both ends of the synchronizing rod are fixedly connected to the two driven wheels. The driving motor 811 drives one of the driving wheels to rotate. The driving motor 811 drives one of the driving wheels to rotate. The driving wheel drives the chain belt to rotate, and drives the door panel 1 to move along the chain belt. The chain belt drives the driven wheel to rotate, the driven wheel drives the synchronizing rod to rotate, and the synchronizing rod drives the other chain belt group 812 to move.

[0061] Specifically, a sealing ring 34 is provided on the sealing plate 3. The sealing ring 34 corresponds to the sealing opening of the sealing frame 9, realizing the tight connection between the sealing plate 3 and the sealing frame 9, and preventing external gases, impurities, moisture, etc. from entering the cavity connected to the sealing frame 9.

[0062] Embodiment 2

[0063] See Figures 1-11 As shown, this embodiment discloses a sealing door mechanism, including: two sealing doors of Embodiment 1, and two sealing frames 9; the two sealing frames 9 are arranged in parallel, and the door panel 1 is connected to the sealing frame 9 through a door closing assembly 8. A sealing opening 91 is provided on the sealing frame 9. The two fixing plates 82 are located on both sides of the sealing opening 91 and are fixedly connected to the sealing frame 9. The sealing frame 9 is connected to the opening of the equipment, passage, cavity. The two sealing doors are independent of each other and can be aligned with or away from the sealing opening 91 under the drive of their respective translation driving members 81, and the sealing plate 3 is maintained in the extended or retracted state to achieve sealing and unsealing, so that each sealing opening 91 can respond to the demand when there is a need for sealing or opening. When one of the sealing doors fails or needs to be repaired, the other sealing door can still be used normally, improving the safety and reliability of the system.

[0064] Specifically, there is a gap between the two sealing frames 9; the sealing door seals and covers the sealing frame 9 or is located between the two sealing frames 9. The fixing plate 82 extends from one end of the sealing opening 91 towards the direction close to the other sealing opening 91, so that when the sealing door does not need to work, it can move between the two sealing frames 9, avoiding the protrusion of the sealing door from the structures such as equipment, passage or cavity in the open state, greatly saving the occupied space of the sealing door and improving the space utilization rate.
