[0030] With reference to Figure 1 , Figure 3 , Figure 4 , the utility model provides an embodiment: a spliced elbow assembly, including elbow pipeline 1, elbow pipeline 1 generally adopts high -quality metal material to be made, such as stainless steel material, it has good corrosion resistance, can adapt to the conveying of multiple different medium in pipeline, guarantees the long -term stable use of pipeline. The outer side of elbow pipeline 1 is fixedly connected with fixed column 2, and fixed column 2 can select high -strength carbon steel material, is processed after special forging process, has the characteristics of firm and durable, can bear the stress generated in the subsequent installation, use process, ensure the stability of overall structure.

[0031] The inside of fixed column 2 is slidably connected with sliding column 3, and sliding column 3 is also made of reliable strength metal material, such as alloy steel material, and has moderate hardness, which can ensure smooth sliding in fixed column 2 and effectively support and fix during connection. The outer side of sliding column 3 is fixedly connected with a plurality of limiting blocks 4, and limiting blocks 4 are generally made of wear-resistant alloy steel material, which is finely processed to make the surface smooth, cooperate more smoothly with the clamping groove 8, and has good wear resistance, which can reduce wear after long-term use and ensure the accuracy and reliability of connection.

[0032] A plurality of clamping grooves 8 are formed in the inside of fixed column 2, and the clamping grooves 8 are designed as L-shaped. The L-shaped design is very ingenious. When installing, the limiting block 4 slides along the clamping groove 8. When the sliding column 3 is rotated, the limiting block 4 can be clamped at the corner of the clamping groove 8, thereby realizing stable limiting of the pipeline and preventing axial or radial displacement. The size accuracy of the clamping groove 8 is high to ensure close cooperation with the limiting block 4. The inner wall of the clamping groove 8 is polished to make the sliding process smoother. The outer side of the limiting block 4 is slidably connected in the inside of the clamping groove 8, and the close cooperation of the two realizes the preliminary positioning of the pipeline during installation, provides an accurate basic position for subsequent sealing and fastening operation, and makes the entire connection process more orderly.

[0033] The inside of the fixed column 2 is fixedly connected with a fixed ring 9, which can be made of high-strength cast iron material, has stable structure, can provide reliable support basis for the whole sealing assembly, and can bear the pressure generated by the sealing assembly during work, so as to ensure that the sealing effect is not affected. One end of the sliding column 3 is slidingly connected to one side of the fixed ring 9. This sliding connection mode enables the sliding column 3 to smoothly enter the inside of the fixed column 2 during installation, and creates conditions for the compression, rebound and other actions of the sealing assembly, so as to ensure that each step of sealing and connection is smoothly completed. The other side of the fixed ring 9 is fixedly connected to the outside of the elbow pipe 1, further enhancing the relevance and stability of the overall structure, so that the elbow pipe 1, the fixed column 2 and the sealing assembly form a close whole, and provide strong protection for the stable operation of the pipe connection. Embodiment

[0034] Reference Figures 2 to 4 The inside of the fixed column 2 is fixedly connected with a sealing assembly for sealing the parts. The sealing assembly comprises a limiting ring 10, the outside of which is fixedly connected to the inside of the sliding column 3. The limiting ring 10 can be made of a metal material with good toughness, such as copper alloy material. It can stably move with the movement of the sliding column 3 during installation, and can better maintain structural stability when the sealing assembly is subjected to pressure changes, thereby ensuring the sealing effect.

[0035] One side of the limiting ring 10 is fixedly connected with a sealing shell 5, and the outside of the sealing shell 5 is slidingly connected to the outside of the fixed ring 9. The sealing shell 5 can be made of an engineering plastic material with good sealing performance and certain strength, which can smoothly slide outside the fixed ring 9 and provide effective protection for the internal sealing ring 7 and other components, ensuring the integrity of the sealing structure. The inside of the sealing shell 5 is fixedly connected with a spring 6, and the other end of the spring 6 is fixedly connected to the inside of the sealing ring 7. The spring 6 is generally made of high-quality spring steel material, has good elasticity and fatigue resistance, can be compressed to store elastic potential energy during installation, and can provide rebound force after installation by releasing the elastic potential energy, so that the sealing ring 7 tightly fits the fixed ring 9, realizes reliable sealing effect, and can repeatedly compress and rebound without failure during long-term use.

[0036] The inside of the sealing shell 5 is slidingly connected with a sealing ring 7, and the outside of the sealing ring 7 is slidingly connected to one side of the fixed ring 9. The sealing ring 7 is usually made of rubber material, which has excellent flexibility and sealing performance, can fully fill the small gaps in the sealing part when subjected to the extrusion of the spring 6 and the pressure during installation, effectively prevents leakage of the medium in the pipeline, and ensures the sealing performance of the pipeline device.

[0037] When the worker needs to connect the elbow pipe 1 with the pipe, the sliding column 3 can be taken out from the inside of the elbow pipe 1, and then the sliding column 3 can be slid into the inside of the fixed column 2 after being fixed outside the pipe. The outside of the sliding column 3 is connected with a plurality of limiting blocks 4, which can limit the pipe in the inside of the fixed column 2 by cooperating with the clamping grooves 8 in the inside of the fixed column 2. When the sealing shell 5 slides to the specified position in the inside of the clamping groove 8, the sliding column 3 can be rotated and clamped in the inside of the clamping groove 8, so as to connect the pipe with the elbow pipe 1. When the sliding column 3 slides into the inside of the fixed column 2, the sealing ring 7 is compressed downward because it abuts against the inside of the fixed ring 9, so that the sealing ring 7 compresses the plurality of springs 6. When the worker releases the sliding column 3 after installation, the compressed springs 6 lose pressure and provide elastic force, so that the fixed column 2 and the sliding column 3 are connected more tightly after installation. When the pipe needs to be disassembled, the sliding column 3 can be rotated in the opposite direction, and the limiting blocks 4 are released from the clamping groove 8, so as to realize disassembly.

[0038] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
