[0020] Reference Figure 1-Figure 3 As shown, Figure 1 This is a schematic diagram of the structure of the core fixing device and the shell provided in the embodiment of the present application. Figure 2 An exploded view of the core fixing device and the shell provided in the embodiment of the present application, Figure 3 A schematic diagram of the structure of a core fixing device provided in an embodiment of the present application. This embodiment discloses a core fixing device, which is installed in a sealing device, and the sealing device includes a shell 100, and the shell 100 is provided with an air outlet 101. The core fixing device includes a bracket 1, a movable component 2 and a driving component 3, and the bracket 1 includes a support plate 11, a first fixed plate 12 and a second fixed plate 13, and the first fixed plate 12 and the second fixed plate 13 are respectively arranged at both ends of the bracket 1 along the width direction. The movable component 2 includes a first movable part 21 and a second movable part 22 for supporting the core 5, and the first movable part 21 and the second movable part 22 are respectively movably arranged on both sides of the bracket 1 along the length direction, and the opposite sides of the first movable part 21 and the second movable part 22 are provided with inclined surfaces 23. The driving assembly 3 is disposed on the bracket 1 and connected to the first movable member 21 and the second movable member 22 respectively, and is used to drive the first movable member 21 and the second movable member 22 to move toward or away from each other along the length direction, so that the inclined surface 23 drives the core 5 to move up and down along the height direction to block the air outlet 101 or move away from the air outlet 101. Figure 3 The X direction in the width direction is Figure 3 The Y direction in the default direction is Figure 3The Z direction is the height direction. The air outlet 101 can be an air inlet or an air outlet. The core fixing device can be installed at the air inlet and / or the air outlet as required, and the distance between the core fixing device and the air outlet 101 can be set according to the thickness of the core 5. It is only necessary to make the core 5 fit closely with the peripheral side of the air outlet 101 after the first movable part 21 and the second movable part 22 are completely contracted.

[0021] During operation, the driving component 3 drives the first movable part 21 and the second movable part 22 to move toward each other in the length direction, so that the inclined surface 23 pushes the core body 5 to move in the height direction in the direction close to the air outlet 101 to block the air outlet 101; when the core body 5 needs to be removed, the driving component 3 drives the first movable part 21 and the second movable part 22 to move away from each other in the length direction, so that the core body 5 descends along the inclined surface 23 due to gravity to move in the height direction in the direction away from the air outlet 101.

[0022] In this embodiment, the support plate 11 is provided with a hollow portion 110, and the hollow portion 110 is arranged corresponding to the core body 5, which reduces the weight of the bracket 1 and reduces the cost, and facilitates the air to enter the core body 5 from the hollow portion 110, reduces the situation where the bracket 1 hinders the air flow through the core body 5, and ensures the normal operation of the core body fixing device.

[0023] In this embodiment, the core fixing device also includes a seal 4, which is arranged on the side of the core 5 facing the air outlet 101, and the seal 4 is distributed along the circumference of the core 5, so that when the core 5 is sealed at the air outlet 101, the sealing between the core 5 and the shell 100 on the circumference of the air outlet 101 can be further strengthened, thereby ensuring the sealing effect.

[0024] The first movable member 21 and the second movable member 22 of this embodiment are provided with inclined surfaces 23 on the opposite sides. When working, the first movable member 21 and the second movable member 22 are driven by the driving component 3 to move toward each other along the length direction, so that the inclined surfaces 23 of the first movable member 21 and the second movable member 22 push the core body 5 to move along the preset direction to seal the air outlet 101. The core body 5 is pressed against the air outlet 101 by the movable component 2, thereby ensuring the sealing effect on all sides between the core body 5 and the shell 100. When disassembling the core body 5, the first movable member 21 and the second movable member 22 are driven by the driving component 3 to move in opposite directions along the length direction, so that the core body 5 slides down along the inclined surface 23, and then the core body 5 can be directly taken out without sealing by screws, which facilitates the disassembly and assembly of the core body 5, reduces the disassembly and assembly cost, and improves work efficiency.

[0025] Reference Figure 3As shown, the driving assembly 3 includes a driving member 31, a screw rod 32, a first nut 33, a second nut 34 and a plurality of movable connecting rods 35. The screw rod 32 is respectively arranged in the first fixed plate 12 and the second fixed plate 13, and the screw rod 32 is located between the first movable member 21 and the second movable member 22, and the length of the screw rod 32 extends in the width direction. The first nut 33 and the second nut 34 are respectively connected to the screw rod 32, and both sides of the first nut 33 and the second nut 34 are respectively connected to the first movable member 21 and the second movable member 22 through a movable connecting rod 35. The driving member 31 is connected to the screw rod 32, and is used to drive the screw rod 32 to rotate, so that the first nut 33 and the second nut 34 can move toward or away from each other in the width direction, so as to drive the first movable member 21 and the second movable member 22 to move toward or away from each other in the length direction. The first nut 33 and the second nut 34 simultaneously drive the first movable member 21 and the second movable member 22 to move, thereby improving the stability of the movement of the first movable member 21 and the second movable member 22.

[0026] In this embodiment, one end of a movable link 35 is rotationally connected to one side of the first nut 33, and the other end is rotationally connected to the middle of the first movable part 21. One end of a movable link 35 is rotationally connected to the other side of the first nut 33, and the other end is rotationally connected to the middle of the second movable part 22. When the first nut 33 is located at the end of the screw rod 32, the movable link 35 is in an "eight" shape, and is connected to the middle of the first movable part 21 and the second movable part 22, thereby ensuring the stability of the first nut 33 when driving the first movable part 21 and the second movable part 22 to move during movement. In this embodiment, the driving member 31 is configured as a handle knob, which is connected to one end of the screw rod 32 . The screw rod 32 is driven to rotate forward or reverse by manually turning the handle knob.

[0027] In one embodiment, the driving component 3 also includes a controller, which is electrically connected to the driving member 31. The controller can control the driving member 31 to drive the screw rod 32 to rotate forward or reverse through electrical signals, thereby realizing automatic control of the core fixing device and improving work efficiency. The driving member 31 can be an electric structure or a pneumatic structure, such as a motor or a cylinder.

[0028] Reference Figure 3-Figure 5 As shown, Figure 4 This is a schematic structural diagram of a core body of a core body fixing device provided in an embodiment of the present application in a placement plane, Figure 5A schematic diagram of the structure of the core of the core fixing device provided in the embodiment of the present application is in the installation plane. A placement plane 24 is also provided on the opposite sides of the first movable member 21 and the second movable member 22, and the core 5 is arranged on the placement plane 24. The inclined plane 23 is connected to the placement plane 24. When the first movable member 21 and the second movable member 22 move toward each other along the length direction, the core 5 can move from the placement plane 24 to the inclined plane 23 along the height direction. The placement plane 24 is used to support the core 5 when the first movable member 21 and the second movable member 22 are not moving, so as to reduce the situation in which the core 5 is damaged due to the squeezing force generated by the inclined plane 23 on the core 5 due to the support of the core 5 by the inclined plane 23, thereby ensuring the service life of the core 5 and reducing the maintenance cost of the core 5.

[0029] In this embodiment, a transition surface 26 is provided between the inclined surface 23 and the placement plane 24. The transition surface 26 is an arc-shaped surface. The arc-shaped surface can better guide the movement of the core 5 when the core 5 moves from the placement plane 24 to the inclined surface 23 along the height direction, thereby ensuring the stability and reliability of the movement of the core 5. Reference Figure 3-Figure 5 As shown, the first movable member 21 and the second movable member 22 are both provided with a limiting step 25 on the opposite side thereof. The limiting step 25 includes a mutually perpendicular mounting plane 250 and a limiting surface 251. The mounting plane 250 is located at the end of the inclined surface 23 away from the placement plane 24, and the mounting plane 250 is parallel to the placement plane 24. The limiting surface 251 is located at the end of the mounting plane 250 away from the inclined surface 23. When the first movable member 21 and the second movable member 22 move toward each other along the length direction, the core 5 can move from the placement plane 24 to the inclined surface 23 along the height direction, and then move from the inclined surface 23 to the mounting plane 250. The mounting plane 250 is used to support the core 5 when the core 5 is blocked in the air outlet 101, so as to reduce the situation that the core 5 is damaged due to the squeezing force generated by the inclined surface 23 on the core 5 by the core 5 supported by the inclined surface 23, thereby ensuring the service life of the core 5 and reducing the maintenance cost of the core 5. The limiting surface 251 is used to limit the core body 5 in the length direction when the core body 5 is blocked at the air outlet 101 , so as to reduce the deviation of the core body 5 , thereby ensuring the stability and reliability of the core body 5 when abutting against the shell 100 .

[0030] In this embodiment, a transition surface 26 is provided between the mounting plane 250 and the inclined surface 23. The transition surface 26 is an arc-shaped surface. The arc-shaped surface can better guide the movement of the core body 5 when the core body 5 moves from the inclined surface 23 to the mounting plane 250 along the height direction, thereby ensuring the stability and reliability of the movement of the core body 5.

[0031] In a specific application scenario, when installing the core body 5, the controller controls the screw rod 32 to rotate forward (i.e., rotate clockwise), and the first nut 33 and the second nut 34 move in opposite directions in the width direction to pull the movable link 35 to contract inward in the length direction. The movable link 35 drives the first movable member 21 and the second movable member 22 on both sides to move in opposite directions in the length direction. At this time, the core body 5 located on the placement plane 24 will move from the placement plane 24 along the inclined surface 23 to the installation plane 250 in the height direction under the extrusion of the inclined surface 23, and will be blocked at the air outlet 101 by the extrusion of the first movable member 21 and the second movable member 22, and then the screw rod 32 will be locked; When removing the core body 5, the controller controls the screw rod 32 to reverse (i.e., rotate counterclockwise), and the first nut 33 and the second nut 34 move in opposite directions in the width direction to push the movable connecting rod 35 to open outward in the length direction. The movable connecting rod 35 drives the first movable part 21 and the second movable part 22 on both sides to move in opposite directions in the length direction. At this time, when the core body 5 located on the installation plane 250 moves in opposite directions with the first movable part 21 and the second movable part 22, it slides down from the installation plane 250 along the inclined surface 23 to the placement plane 24 in the height direction by its own gravity, and then the core body 5 can be directly taken out to complete the replacement of the core body 5. The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
