[0017] Embodiment:

[0018] Please refer to Figure 1 - Figure 4 The present utility model provides a technical solution: a connecting structure for lining the contact surface of a stainless - steel flange on a hot - stamping tank, including: a connecting pipe 1; a limiting mechanism 2, the outer wall of the limiting mechanism 2 is slidably connected to the inner wall of the connecting pipe 1, and two groups of limiting mechanisms 2 are provided; a fixing plate 4, the outer wall of the fixing plate 4 is fixedly connected to the outer walls on both sides of the connecting pipe 1, and the fixing plate 4 is annularly arranged along the central axis of the connecting pipe 1; a sealing mechanism 3, the inner wall of the sealing mechanism 3 is slidably connected to the outer wall of the fixing plate 4, and two groups of sealing mechanisms 3 are provided; the limiting mechanism 2 includes a main ring body 21, the outer wall of the main ring body 21 is rotatably connected to a connecting ring 22 through a rotating shaft 28, and the outer wall of the rotating shaft 28 is rotatably connected to the inner wall of the connecting ring 22. The outer wall of the connecting ring 22 is rotatably connected to a sub - ring body 23 through a pin. One side of the sub - ring body 23 away from the connecting ring 22 is rotatably connected to a positioning plate 25. One side of the main ring body 21 away from the connecting ring 22 is rotatably connected to a limiting plate 26. A locking bolt 27 is slidably connected to the inner wall of the limiting plate 26. The bottom of the rotating shaft 28 is fixedly connected to a slider 24, and the position of the rotating shaft 28 is restricted by the slider 24.

[0019] The outer wall of the slider 24 is slidably connected to the inner wall of the connecting pipe 1. By sliding the slider 24 in the connecting pipe 1, it can adapt to flanges with different outer diameters. The outer wall of the rotating shaft 28 is rotatably connected to the inner wall of the main ring body 21. The sealing mechanism 3 includes a soft ring 32. The outer wall of the soft ring 32 is fixedly connected to a soft shell 34, and the soft shell 34 is annularly arranged along the central axis of the soft ring 32. A sealing ring 31 is arranged outside the soft ring 32.

[0020] The outer wall of the sealing ring 31 is in contact with the outer wall of the soft shell 34. The outer wall of the soft ring 32 is fixedly connected to a soft pad 33, and the soft pad 33 is annularly arranged along the central axis of the soft ring 32. The outer wall of the soft pad 33 is slidably connected to the outer wall of the fixing plate 4. The connecting pipe 1 is sealed by the convex blocks on the soft shell 34 fitting with the sealing ring 31. The outer wall of the fixing plate 4 is slidably connected to the outer wall of the soft ring 32.

[0021] Working principle:

[0022] In use, first install the sealing mechanism 3 on the fixing plate 4 on the connecting pipe 1, then pass the fixing plate 4 with the sealing mechanism 3 installed through the flange and the contact surface liner, so that the contact surface liner fits on the connecting pipe 1, and then use the limiting mechanism 2 to wrap the flange, thereby fixing the connecting pipe 1 on the flange. Then, also install the sealing mechanism 3 on the side of the connecting pipe 1 away from the flange and slide the fixing plate 4 with the sealing mechanism 3 installed into the hot stamping tank connection port. Once again, use the limiting mechanism 2 to wrap the connection port, so as to connect the hot stamping tank and the flange by means of the connection structure.

[0023] When installing the sealing mechanism 3 on the fixing plate 4, just slide the soft ring 32 onto the fixing plate 4 and make the soft pad 33 on the soft ring 32 be between the fixing plates 4, so as to fill the gap between the fixing plates 4. Subsequently, slide the sealing ring 31 onto the soft ring 32 and slide the convex block on the sealing ring 31 between the soft shells 34. After the sealing ring 31 is installed, the flange can be installed on the sealing ring 31. During use, the convex block fits on the soft shell 34, and because the convex block and the soft shell 34 adopt a serrated design, it can prevent the substances in the connecting pipe 1 from leaking out of the sealing mechanism 3. The method of installing the hot stamping tank on the sealing mechanism 3 is the same as the method of installing it on the flange.

[0024] When using the limiting mechanism 2, just unscrew the nut on the locking bolt 27 and slide the slider 24 so that the limiting mechanism 2 can wrap the flange and the hot stamping tank. Subsequently, adjust the positions of the main ring body 21, the sub-ring body 23 and the connecting ring 22 to ensure that the main ring body 21, the sub-ring body 23 and the connecting ring 22 all wrap the flange and the hot stamping tank. Then, pass the locking bolt 27 on the limiting plate 26 through the positioning plate 25 and re-lock the nut on the locking bolt 27 and tighten the nut so that the nut is tightly attached to the positioning plate 25, so as to limit the positions of the main ring body 21, the sub-ring body 23 and the connecting ring 22, thereby fixing the limiting mechanism 2 on the flange and the hot stamping tank. And because the rotating shaft 28 is fixed on the slider 24, the position of the connecting pipe 1 and the limiting mechanism 2 can be restricted.

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
