[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0031] Example 1: A kiln head cover sealing mechanism, see Figures 1 to 4 , including an inspection channel 1, the end of which is fixedly arranged at the inspection port of the kiln head cover, a cover plate 2 is arranged at the inlet end of the inspection channel 1, and also includes a sealing structure 5;

[0032] The sealing structure 5 is arranged inside the cover plate 2;

[0033] The sealing structure 5 includes a sealing frame strip 501 and a supporting frame plate 502;

[0034] The sealing frame strip 501 is fixedly arranged on the inner side of the cover plate 2; wherein the outer wall of the sealing frame strip 501 contacts and cooperates with the inner wall of the entrance end of the maintenance channel 1; the supporting frame plate 502 is fixedly arranged on the inner side of the cover plate 2 of the inner circle of the sealing frame strip 501; wherein the outer wall of the supporting frame plate 502 is fixedly connected with the inner wall of the sealing frame strip 501; wherein there is a gap between the outer wall of the supporting frame plate 502 and the inner wall of the entrance end of the maintenance channel 1, and the supporting frame plate 502 does not contact the inner wall of the entrance end of the maintenance channel 1 when inserted into the entrance end of the maintenance channel 1, and there is no obstruction.

[0035] The utility model has the advantage of supporting the sealing frame strip 501 by providing a sealing frame strip 501 and a supporting frame plate 502. After the sealing frame strip 501 enters the entrance end of the maintenance channel 1, the outer portion of the supporting frame plate 502 cooperates with the inner wall of the entrance end of the maintenance channel 1 to squeeze the sealing frame strip 501, so that the sealing frame strip 501 is restricted and the sealing frame strip 501 does not roll inward, thereby solving the problem that the sealing strip is easily rolled inward due to the influence of temperature and affects the sealing effect.

[0036] Specifically, one end of the cover plate 2 is rotatably connected to the outer wall of one end of the entrance of the inspection channel 1 through two symmetrically arranged hinges 3, and the other end of the cover plate 2 is fixedly matched with the outer wall of the other end of the entrance of the inspection channel 1 through two lock buckles 4. The cover plate 2 rotates relative to the entrance of the inspection channel 1 through the hinge 3, and can be fixed to the entrance end of the inspection channel 1 through the lock buckle 4 to block the entrance of the inspection channel 1, so as to facilitate the operation of opening or closing the cover plate 2.

[0037] Furthermore, the sealing frame strip 501 includes a connecting section 5011, an arched section 5012 and an insertion section 5013, wherein one end of the connecting section 5011 is fixedly arranged on the inner side of the cover plate 2, the other end of the connecting section 5011 is provided with an arched section 5012, and the end of the arched section 5012 which is away from the connecting section 5011 is provided with an insertion section 5013; wherein, the connecting section 5011, the arched section 5012 and the insertion section 5013 are integrally formed; wherein, the arched end of the arched section 5012 faces outward, and the arched section 5012 is snap-fitted with a square slot 101 opened on the inner wall of the entrance end of the inspection channel 1.

[0038] The utility model provides a connecting section 5011, an arched section 5012 and an insertion section 5013, and the arched section 5012 is engaged with the square slot 101, so that the contact sealing area between the outer wall of the sealing frame strip 501 and the inner wall of the entrance end of the inspection channel 1 is increased, thereby enhancing the sealing effect.

[0039] Furthermore, the outer wall of the insertion section 5013 is configured as an inclined surface 5014 . The configuration of the inclined surface 5014 enables the insertion section 5013 to enter the entrance end of the inspection channel 1 more smoothly.

[0040] Working principle: When using the device of the utility model, the end of the inspection channel 1 is fixedly arranged at the inspection port of the kiln head cover. When the kiln head cover needs to be inspected, the lock 4 is opened, the cover plate 2 is rotated to open, and the sealing frame strip 501 and the supporting frame plate 502 are rotated out from the entrance end of the inspection channel 1 along with the cover plate 2, and the kiln head cover is inspected through the inspection channel 1. After the inspection is completed, the cover plate 2 is rotated to close, and the sealing frame strip 501 and the supporting frame plate 502 are rotated and inserted into the entrance end of the inspection channel 1. The setting of the inclined surface 5014 allows the insertion section 5013 to enter the entrance end of the inspection channel 1 more smoothly. During the entry process, the arched section 5012 is squeezed by the inner wall of the entrance of the inspection channel 1 until the cover plate 2 closes the entrance end of the inspection channel 1. The sealing frame strip 501 and the supporting frame plate 502 are completely inserted into the entrance end of the inspection channel 1. At this time, the arched section 5012 is engaged with the square slot 101, thereby sealing the connection between the entrance end of the inspection channel 1 and the cover plate 2.

[0041] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
