[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Such as Figure 1 and Figure 2As shown in the figure, a spliced sealing ring includes an upper sealing structure 1, an elastic support member 2, and a lower sealing structure 3. An upper support groove 15 is provided on the upper sealing structure 1, and a lower support groove 35 is provided on the lower sealing structure 3. The upper support groove 15 is aligned with the lower support groove 35. The upper sealing structure 1 and the lower sealing structure 3 are snap-connected to each other. A support chamber 4 is formed by the cooperation between the upper support groove 15 and the lower support groove 35 after the upper sealing structure 1 and the lower sealing structure 3 are combined. The elastic support member 2 is installed on the support chamber 4 and abuts against the upper sealing structure 1 and the lower sealing structure 3 respectively. After the upper sealing structure 1 or the lower sealing structure 3 is pressed, the elastic support member 2 provides elastic compensation, ensuring the sealing effectiveness of the sealing ring in a high-pressure environment. The upper sealing structure 1 and the lower sealing structure 3 are snap-connected, which is convenient for disassembly and assembly. If the sealing ring is damaged, the damaged part can be disassembled and replaced, thus saving costs.

[0019] The upper sealing structure 1 includes an upper sealing strip 11 and a connecting strip 12. The connecting strip 12 is clamped on the upper sealing strip 11. Limiting blocks 121 are provided at both ends of the connecting strip 12, and limiting grooves 111 are provided at both ends of the upper sealing strip 11. The limiting blocks 121 are clamped in the limiting grooves 111, so that the upper sealing strip 11 and the connecting strip 12 are combined to form the upper sealing structure 1.

[0020] The lower sealing structure 3 includes a lower sealing strip 31. Arc-shaped columns 311 and arc-shaped holes 312 are provided on the lower sealing strip 31. The arc-shaped columns 311 and the arc-shaped holes 312 are respectively provided at both ends of the lower sealing strip 31, and the shape of the arc-shaped column 311 matches that of the arc-shaped hole 312. The arc-shaped column 311 is embedded in the arc-shaped hole 312. Since the arc-shaped column 311 and the arc-shaped hole 312 are in interference fit, their connection is tighter, avoiding the risk of the sealing ring separating due to pressure.

[0021] A first groove 13 and a second groove 14 are provided on the upper sealing structure 1, and a first block 33 and a second block 34 are provided on the lower sealing structure 3. The shape of the first groove 13 matches that of the first block 33, and the shape of the second groove 14 matches that of the second block 34. Thus, the first block 33 is inserted into the first groove 13 and the second block 34 is inserted into the second groove 14, and there is an anti-fooling effect, ensuring that the upper support groove 15 and the lower support groove 35 can be accurately aligned. In particular, the cross-sectional shapes of the first groove 13 and the second groove 14 are dovetail groove type or T-shaped, which can ensure that the lower sealing structure 3 can be tightly clamped with the upper sealing structure 11.

[0022] The upper sealing structure 1 further includes a first docking groove 16 and a first docking block 17, which are respectively arranged on both sides of the upper support groove 15. The lower sealing structure 3 further includes a second docking groove 37 and a second docking block 36, which are respectively arranged on both sides of the lower support groove 35. The first docking block 17 is clamped in the second docking groove 37, and the second docking block 36 is clamped in the first docking groove 16. A U-shaped structure is formed between the first docking block 17 and the upper support groove 15 and between the second docking block 36 and the lower support groove 35, so as to abut against the four ends of the elastic support member 2 to prevent the ends of the elastic support member 2 from disengaging. The cross-section of the elastic support member 2 is cross-shaped, and the four corners of the elastic support member 2 are respectively abutted against the four sides of the support chamber 4.

[0023] When installing the above-mentioned spliced sealing ring, first, the elastic support member 2 is sleeved on the upper sealing strip 11. The end of the lower sealing strip 31 with the arc-shaped column 311 is aligned with the end of the upper sealing strip 11, so that the first card slot 13 is aligned with the first card block 33, and the second card slot 14 is aligned with the second card block 34. Then, the lower sealing strip 31 is pushed to move, so that the upper sealing structure 1 and the lower sealing structure 3 are clamped tightly. After the lower sealing strip 31 surrounds a circle, the arc-shaped column 311 is inserted into the arc-shaped hole 312 to fix the lower sealing structure 1. Subsequently, the limit card block 121 of the connecting strip 12 is aligned with the limit card slot 111 of the upper sealing strip 11, and the limit card block 121 is clamped in the limit card slot 111, so that the upper sealing strip 11 and the connecting strip 12 are combined to form the upper sealing structure 1, thus completing the installation.

Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
