DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Example:

[0031] Reference Figure 1-Figure 5 A sealed door structure includes a door panel 4 for sealing a chamber, which is similar to a combustion or heat-insulating working chamber 1 used in industry. Usually, the end of the working chamber 1 has an opening, and a sealing strip 102 is arranged around the opening. In order to ensure that the sealing strip 102 does not move, a sealing groove is provided or a retaining strip 101 is used to position the sealing strip 102. The sealed door for sealing the opening of the chamber includes: a guide frame mounted on the shell of the working chamber 1 and a retractable driving part rotatably connected to the guide frame, a mounting frame is slidably connected along the length direction of the guide frame, and the door panel 4 is connected to the mounting frame, and at least one "L"-shaped locking plate 6 is preferably two to ensure In terms of usage strength, the end of the short section of the lock plate 6 is rotationally connected to the output end of the driving part, and the end of the long section is rotationally connected to the mounting frame, and the long section is rotationally connected to the door panel 4 through a connecting part. When the driving part is extended, the plane where the door panel 4 is located is parallel to the plane where the guide frame is located, so that the door panel 4 closes the chamber. When the driving part is retracted, the plane where the door panel 4 is located intersects with the plane where the guide frame is located, so that the door panel 4 opens the chamber. In the process of raising and lowering the door panel 4, the door panel 4 slides in a certain inclined manner. The specific inclination angle range is 0°-30°. In the present embodiment, it is preferably 5° so that the bottom of the door panel 4 can contact the baffle 101, which plays a certain role in limiting and triggering the rotation of the door panel 4.

[0032] In the above structure, the lock plate 6 driven in a sliding manner forms a connecting rod mechanism, so that the door panel 4 opens and closes the chamber, and the sliding movement of the door panel 4 that does not contact the sealing strip 102 replaces the hinge structure, thereby avoiding the problem of connection dislocation caused by long-term use of the door panel 4. When the door panel 4 slides to the opening of the chamber, the lock plate 6 can be driven to drive the door panel 4 to rotate and buckle at the opening of the chamber, which can prevent the sealing strip 102 from dislocating, and effectively improves the smooth opening and closing of the door panel 4 and the sealing reliability.

[0033] The specific adapter part includes a rotating shaft rotatably connected to the long section of the lock plate 6, on which a lock rod 601 is rotatably connected, on which a mounting plate 602 is fixedly connected, and on which the mounting plate 602 is fixedly connected to the door panel 4. When the bottom of the door panel 4 contacts the lowest baffle 101, the lock plate 6 will rotate, so that the door panel 4 is buckled at the opening of the chamber, which will neither cause the sealing strip 102 to be misplaced nor compact the sealing strip 102 tightly, thereby greatly improving the sealing effect.

[0034] Reference Figure 3The specific guide frame includes: a crossbeam 201, on which a first rotating seat 202 is arranged, and a cylinder 3 is rotatably connected to the first rotating seat 202; there are also guide rails 2 fixedly connected to both ends of the crossbeam 201, and one end of the guide rail 2 away from the crossbeam 201 is installed on the outer shell chamber of the working chamber 1, and the mounting frame is slidably connected to the guide rail 2, and the crossbeam 201 and the guide rail 2 are on the same plane.

[0035] Reference Figure 3 The mounting frame includes: a mounting beam 5 parallel to the crossbeam 201, wherein a second rotating seat 504 is fixedly connected to the top of the mounting beam 5, and a long end portion of the lock plate 6 is rotatably connected to the second rotating seat 504; guide plates 501 fixedly connected to both ends of the mounting beam 5, and the guide plates 501 are perpendicular to the mounting beam 5, wherein the guide plates 501 are slidably connected to the guide rail 2, and the door panel 4 is driven to rise and fall by the sliding of the mounting frame, which can ensure the stability of the lifting of the door panel 4, and guided by the guide rail 2, which can effectively control the lifting route of the door panel 4 to prevent it from deviating or misaligning.

[0036] The guide rail 2 is composed of two vertical plates and a flat plate, and its cross-section is in the shape of a "concave" character. A limit block 203 is arranged in the guide rail 2, and the guide plate 501 can be offset against the limit block 203. The limit block 203 limits the maximum height of the door panel 4. This can prevent the door panel 4 from failing to rotate when it rises to the opening of the cavity, thereby effectively improving the reliability of the closure.

[0037] A reinforcing plate 502 is installed between the mounting beam 5 and the guide plate 501. Guide wheels are installed on both the reinforcing plate 502 and the guide plate 501. The guide wheels may be rollers or bearings. The guide wheels on the reinforcing plate 502 fit with the outer facade of the vertical plate, and the guide wheels on the guide plate 501 fit with the inner side of the vertical plate. The outer facade and the inner facade are adjacent surfaces, which can further improve the lifting accuracy of the entire mounting frame and enable the door panel 4 to accurately close the cavity opening.

[0038] In addition, a limit rod 503 is installed on the reinforcing plate 502, and the limit rod 503 can be against the door panel 4, mainly to prevent the door panel 4 from being damaged due to excessive rotation due to impact.

[0039] The driving part can be a telescopic device that can be controlled automatically, such as a cylinder 3 or a hydraulic cylinder. The output end of the cylinder 3 selected here is slidably connected to the telescopic rod 301, and the short section of the locking plate 6 is rotatably connected to the hinge joint 603. The end of the telescopic rod 301 away from the cylinder 3 is fixedly connected to the hinge joint 603, and the cylinder 3 drives the entire mounting frame to rise and fall stably.
