[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this application and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Furthermore, in this application, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Moreover, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] First embodiment:

[0033] Please refer to Figure 1(Refer to) Figures 2 to 5 This application provides a sealing connection structure, which mainly includes a sealing steel ring 1 and two O-rings 2. Each end of the sealing steel ring 1 has a groove 3 that matches the O-ring 2. Each O-ring 2 is engaged within its corresponding groove 3. Furthermore, the grooves 3, the sealing steel ring 1, and the two O-rings 2 are coaxially arranged. Therefore, by providing O-rings 2 at both ends of the sealing steel ring 1, the structure achieves excellent sealing performance, effectively improving the sealing performance of the clamp connection component and solving the problem of pipeline leakage. Simultaneously, the O-rings 2 are inexpensive and easy to replace, solving the problems of easy damage and high replacement costs of the existing sealing steel ring 1, achieving a green and environmentally friendly effect, and reducing the labor intensity of workers.

[0034] It should be noted that in this embodiment, the sealing steel ring 1 has an inner ring and an outer ring. The inner ring has a first chamfer 4, and the outer ring has a second chamfer 5. Specifically, the first chamfer 4 can be designed to be 60°, and the second chamfer 5 can be designed to be 60°, so that the sealing steel ring 1 can better fit on the clamp body, resulting in a better sealing effect. In other embodiments, the first chamfer 4 and the second chamfer 5 can also be designed to be 45°, 75°, etc., and are not limited to the design form in this embodiment. In addition, the diameter of the O-ring 2 is larger than the diameter of the inner ring and smaller than the diameter of the outer ring.

[0035] It should be noted that, in this embodiment, the sealing steel ring 1 can be an O-ring.
