[0042] Example 1

[0043] like Figures 1 to 12 As shown, a large electric thermal insulation door includes a door frame 1 and two thermal insulation doors 2 respectively hinged on both sides of the door frame 1. A driving structure for driving the thermal insulation doors 2 to rotate is fixed on the door frame 1. The driving structure is used to drive the two thermal insulation doors 2 to rotate in a direction close to or away from each other, thereby realizing the rotation of the thermal insulation doors 2 on the door frame 1.

[0044] The side of the thermal insulation door 2 close to each other is fixedly installed with a door body sealing structure;

[0045] The door body sealing structure includes a limit shell 3 fixedly connected to the side of the thermal insulation doors 2 close to each other. The limit shell 3 is fixedly connected to the limit shell 3 by bolts, so as to facilitate production, processing and installation. An extension part 4 is slidably connected inside the limit shell 3. An elastic component is arranged between the limit shell 3 and the extension part 4. The elastic component can be a tension spring. In the initial state, under the action of the tension spring, the extension part 4 is pulled into the limit shell 3. The extension parts 4 on the two thermal insulation doors 2 can abut against each other to seal the gap between the two thermal insulation doors 2;

[0046] A sealing drive structure is provided on the door frame 1 for pushing the extension part 4 to slide. The sealing drive structure is used to push the extension part 4 in a direction close to each other so that the sides of the extension part 4 close to each other are tightly fitted, thereby sealing the gap between the two insulation doors 2 and improving the insulation effect of the insulation door 2; the sealing drive structure can use a hydraulic cylinder or the like to push the extension part 4 to slide inside the limit shell 3.

[0047] When in use, the thermal insulation door 2 rotates on the door frame 1, so that the two thermal insulation doors 2 on the door frame 1 fit with the door frame 1 and the thermal insulation door 2 is closed. At this time, the extension part 4 is pushed in a direction close to each other to seal the gap between the two thermal insulation doors 2, thereby improving the thermal insulation effect of the thermal insulation door 2.

[0048] This embodiment provides a sealing drive structure. Figure 4 , including a driving shaft 5 fixedly connected to the upper and lower ends of the thermal insulation door 2, the driving shaft 5 is arranged on the side where the two thermal insulation doors 2 are close to each other, and a guide groove 6 for pushing the driving shaft 5 to move is opened on the door frame 1, and the guide groove 6 is obliquely arranged on the door frame 1. When the thermal insulation door 2 approaches the door frame 1, the driving shaft 5 slides into the guide groove 6, and continues to push the thermal insulation door 2 to slide in the direction close to the door frame 1, so that the driving shaft 5 slides in the guide groove 6, and is guided by the inclined surface of the guide groove 6 so that the driving shaft 5 pushes the extension part 4 to move in the direction away from the limit shell 3, so that the side of the extension part 4 close to each other is tightly fitted, thereby sealing the gap between the two thermal insulation doors 2 and improving the thermal insulation effect of the thermal insulation door 2.

[0049] The ends of the guide grooves 6 that are close to each other are each provided with an arc-shaped limit groove 7. When the thermal insulation door 2 and the door frame 1 are fitted together, the drive shaft 5 slides into the limit position inside the guide groove 6. At this time, the drive shaft 5 slides into the arc-shaped limit groove 7, so that the drive shaft 5 is stuck into the arc-shaped limit groove 7, thereby limiting the drive shaft 5 to the current position.

[0050] The heat-insulating door 2 is composed of a frame welded by section steel and heat-insulating materials filled in the frame, so as to facilitate processing and installation and improve the heat-insulating effect.

[0051] A sealing rubber pad 8 is provided on the door frame 1 . When the thermal insulation door 2 and the door frame 1 are fitted together, the thermal insulation door 2 presses the sealing rubber pad 8 to improve the sealing effect between the thermal insulation door 2 and the door frame 1 .

[0052] The driving structure includes a reducer 9 fixedly connected to both sides of the door frame 1, the reducer 9 is driven by a driving motor, the rotating shaft end of the reducer 9 is fixedly connected to one end of a swing rod 10, the other end of the swing rod 10 is rotatably connected to a push rod 11, and the other end of the push rod 11 is connected to the thermal insulation door 2. When in use, when the door needs to be opened or closed, the driving motor is started, the driving motor drives the reducer 9 to rotate, the reducer 9 drives the swing rod 10 to swing, when the swing rod 10 swings, it drives the push rod 11 to move synchronously, and when the push rod 11 moves, it drives the thermal insulation door 2 to rotate on the door frame 1, thereby realizing the control of the thermal insulation door 2 to rotate on the door frame 1.

[0053] The upper and lower ends of the thermal insulation door 2 are slidably connected with a clamping rod 12, which is arranged on the side of the thermal insulation door 2 close to each other. The clamping rod 12 can slide in the direction close to or away from the thermal insulation door 2. A sliding member 13 is slidably connected to the thermal insulation door 2. A sliding groove is provided on the frame of the thermal insulation door 2. The sliding member 13 is slidably connected inside the sliding groove. The sliding member 13 and the end of the push rod 11 close to the thermal insulation door 2 are rotatably connected. A driving rod 14 is arranged between the sliding member 13 and the clamping rod 12. The clamping rod 1 2, a chamfer is provided on the top of the door frame 1, a pressing groove 15 matching with the pressing rod 12 is provided on the door frame 1, and a chamfer matching with the pressing rod 12 is provided on one side of the pressing groove 15; when in use, the reducer 9 drives the swing rod 10 to swing, the swing rod 10 drives the push rod 11 to move, and the push rod 11 drives the sliding member 13 to slide on the door frame 1, so that the sliding member 13 moves in a direction close to or away from the limiting housing 3, thereby moving in a direction close to or away from the pressing groove 15 through the driving rod 14;

[0054] A limiting groove 16 is provided on the pressing rod 12 , and one end of the extending portion 4 close to the heat-insulating door 2 is fixedly connected to a limiting rod 17 , and the limiting rod 17 and the limiting groove 16 are slidably connected.

[0055] When in use, in the initial position, the thermal insulation door 2 and the door frame 1 are in a separated state, and the sliding member 13 is in an extreme position away from the limiting housing 3. At this time, the limiting rod 17 is inserted into the limiting groove 16 provided on the pressing rod 12, so that the pressing rod 12 cannot move at will, and the sliding member 13 is limited to the current position by the driving rod 14. At this time, the pushing rod 11 is pushed, and the pushing rod 11 pushes the thermal insulation door 2 to rotate on the door frame 1;

[0056] When the drive shaft 5 slides into the limit position inside the guide groove 6, the inclined surface of the guide groove 6 guides the drive shaft 5 to push the extension part 4 to move in the direction away from the limit shell 3, thereby stretching the tension spring between the extension part 4 and the limit shell 3, and at this time the limit rod 17 slides out from the limit groove 16. At this time, the clamping rod 12 can move freely and continue to push the swing rod 10 to swing through the reducer 9. The swing rod 10 continues to push the push rod 11 to move, and the push rod 11 pushes the sliding member 13 to move to the limit position in the direction close to the limit shell 3. At this time, the clamping rod 12 is pushed by the drive rod 14 to move in the direction close to the clamping groove 15, so that the clamping rod 12 is stuck in the clamping groove 15, and the inclined surface of the clamping rod 12 and the inclined surface of the clamping groove 15 are in contact, so that the thermal insulation door 2 is pressed in the direction close to the door frame 1, thereby improving the sealing, until the straight edge of the clamping rod 12 and the straight edge of the clamping groove 15 are in contact, the thermal insulation door 2 and the door frame 1 are restricted to the current position;

[0057] After use, pull the sliding member 13 in the direction away from the limiting shell 3, thereby pulling the clamping rod 12 in the direction away from the clamping groove 15 through the driving rod 14 until the sliding member 13 slides to the extreme position away from the limiting shell 3, and then continue to pull the thermal insulation door 2 to separate the thermal insulation door 2 and the door frame 1. At this time, the driving shaft 5 slides from the inside of the arc-shaped limiting groove 7 into the inside of the guide groove 6, and the thermal insulation door 2 continues to be rotated. At this time, the driving shaft 5 slides out from the inside of the guide groove 6, so that the extension part 4 slides into the inside of the limiting shell 3 under the action of the tension spring.

[0058] The door frame 1 is provided with a sealing member 18 for sealing the extension portion 4. The sealing member 18 is used to seal the gap between the extension portion 4 and the door frame 1, thereby further improving the sealing performance.

[0059] A plurality of rollers 19 cooperating with the limiting rod 17 are rotatably connected inside the limiting groove 16 , so that the limiting rod 17 can slide inside the limiting groove 16 .

[0060] The side of the extensions 4 close to each other is fixedly connected with a rubber sealing strip 20, and a plurality of isosceles trapezoidal sealing blocks 21 arranged at intervals are fixedly connected to the rubber sealing strip 20, so that the side of the two extensions 4 close to each other can be more closely fitted, thereby improving the sealing performance. When the two extensions 4 slide in the direction of approaching each other, the inclined surfaces of the isosceles trapezoidal sealing blocks 21 arranged on the two rubber sealing strips 20 can be closely fitted to each other, thereby achieving sealing.
