[0002] A pipeline is a system assembly mainly used for transporting gases, liquids or fluids with solid particles, and is widely used in various industries. A pipeline is mainly composed of pipes, pipe connectors, valves, etc., and its material can be metal or non-metal, such as new materials like fluoroplastics. During the use of a pipeline, in order to change the pipeline direction, thereby effectively changing the fluid flow direction, reducing pressure loss and improving transportation efficiency, a connection elbow is used to connect two groups of pipelines.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-6 , the present utility model provides a technical solution: a pipe connection elbow with good sealing performance, including a connection elbow 2. Pipes 1 are respectively arranged at both ends of the connection elbow 2, and connection sleeves are respectively arranged on the pipes 1 and the connection elbow 2. A plurality of groups of sliding grooves are respectively formed on the outer sides of both ends of the connection elbow 2, and sliders 3 are respectively inserted into the sliding grooves. A first bolt 4 is screwed on the slider 3, and the other end of the slider 3 is connected to a rubber sleeve 5.

[0021] Furthermore, the rubber sleeve 5 is inserted into the sliding groove of the connection elbow 2 through the slider 3 to form a sliding structure with the connection elbow 2, and the slider 3 is screwed with the connection elbow 2 through the first bolt 4 to form a screw locking structure. Thus, the movable rubber sleeve 5 can increase the sealing performance at the connection of the pipe 1 and the connection elbow 2 without affecting the installation of the connection elbow 2.

[0022] A plurality of groups of fixing plates 6 are respectively arranged on the outer sides of the rubber sleeve 5. Hollow rods 7 are respectively arranged on the outer walls at both ends of the fixing plate 6, and fixing blocks 10 are correspondingly arranged on the outer walls at both ends of the other group of fixing plates 6. Springs 8 are arranged in the hollow rods 7, and the other ends of the springs 8 are connected to the limiting rods 9. The limiting rods 9 are inserted into the fixing blocks 10. Elastic limiting blocks 11 are respectively arranged on the outer walls on both sides of the lower end of the limiting rod 9, and limiting holes are correspondingly formed on the outer walls on both sides of the fixing block 10. The elastic limiting blocks 11 are respectively inserted into the limiting holes.

[0023] Furthermore, the fixing plate 6 is elastically clamped and limited with the fixing block 10 through the hollow rod 7, the limiting rod 9, and the elastic limiting block 11 inserted into the limiting hole, and the hollow rod 7 forms an elastic telescopic structure with the limiting rod 9 through the spring 8. Thus, the fixing plate 6 connected by clamping applies a relative acting force to the rubber sleeve 5, further increasing the protection of the connection of the rubber sleeve 5 to the connection elbow 2.

[0024] Protective sleeves 12 are respectively placed at both ends of the connecting elbow 2, and connecting plates 13 are respectively provided at both ends of the protective sleeve 12. Second bolts 14 are respectively screwed on the connecting plates 13, and the other ends of the second bolts 14 are screwed on the connecting elbow 2.

[0025] Furthermore, the protective sleeve 12 and the connecting elbow 2 form a screw locking structure through the connecting plate 13 and the second bolt 14. Thus, before the connecting elbow 2 is used, the surface of the connecting elbow 2 is protected by the screw-mounted protective sleeve 12, thereby preventing impurities from adhering to its surface and affecting the sealing performance of the connection.

[0026] Working principle: When using a pipe connecting elbow with good sealing performance, first, during the movement of the connecting elbow 2, the protective sleeve 12 can be installed at both ends of the connecting elbow 2 through the second bolt 14, so as to effectively protect the surfaces at both ends through the protective sleeve 12, thereby preventing impurities from adhering to the surface of the connecting elbow 2 during the installation process and affecting its subsequent sealing performance; when the connecting elbow 2 is connected to the pipe 1, the second bolt 14 can be unscrewed and removed, so as to remove the protective sleeve 12 as a whole, so as to assemble the connecting elbow 2 and the pipe 1 through the connecting sleeve. After the connecting elbow 2 and the pipe 1 are assembled, the rubber sleeve 5 is driven to move as a whole by the slider 3. When the rubber sleeve 5 is closely attached to the connection, it can be screwed and installed through the first bolt 4, so as to increase the sealing performance of the connections at both ends of the connecting elbow 2 through the rubber sleeve 5; then the fixing plate 6 can be placed outside the rubber sleeve 5, and at the same time, the elastic limiting block 11 can be pressed, so that under the action of the spring 8, the limiting rod 9 penetrates into the fixing block 10, and the elastic limiting block 11 penetrates into the limiting hole to lock and limit the limiting rod 9, so that under the action of the spring 8, the two fixing plates 6 apply a relative force to the rubber sleeve 5, further increasing the sealing performance during the installation of the connecting elbow 2. This is the usage process of the pipe connecting elbow with good sealing performance.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
