Description

Technical Field

[0001] The utility model relates to the technical field of clamp assemblies, in particular to a pipeline flexible clamp assembly. Background Art

[0002] Existing wastewater system water supply pipelines usually use AS1650 series flexible connections. In this connection method, the two pipe joints at the connection position are butt-jointed, sealed with a single sealing ring, and fixed with a clamp. This connection method does not reserve an adjustment margin at the butt joint. During the pipeline installation process, the joint position is prone to shaking and needs to be fixed with a flexible clamp assembly.

[0003] The existing pipeline flexible clamp assembly (Announcement No.: CN219221538U) has at least the following disadvantages:

[0004] In the above patent, the elastomer is in a compressed state. When the two clamps are relatively loose, the elastomer stretches, thereby automatically tightening the two clamps, thereby keeping the two clamps in a tight state. However, the elastic force of the elastomer will be affected by different production quality. At the same time, the harsh use environment in the later stage will cause the elastomer to rust, etc., making it difficult to keep the elastic force of the elastomer within the required elastic force range. Therefore, when the two clamps are relatively loose, the elastic force of the elastomer is insufficient to automatically tighten the two clamps, making it difficult for the two clamps to keep in a tight state, which has certain limitations.

[0025] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0026] By means of the provided right clamp 1, when the user needs to connect the first tubular joint 3 and the second tubular joint 4, the second sealing ring 24 is sleeved around the connection between the end protrusions of the first tubular joint 3 and the second tubular joint 4 and the pipe body, and then the first sealing ring 23 is sleeved on the protruding portion of the first tubular joint 3, so that the right clamp 1 and the left clamp 2 are rotated and closed to squeeze the connection between the first tubular joint 3 and the second tubular joint 4, thereby sealing the first sealing ring 23 and the second sealing ring 24, and at the same time, the fixing plate 21 is moved so that the first connecting plate 8 rotates to drive the threaded column 11 to align with the second fixing hole 10 and insert it, and then, the spring 12 is sleeved on the outside of the threaded column 11, so that the limiting column 19 enters the inside of the fixing groove 18. At this time, the limiting column 19, the connecting ring 20, the spring 12 and the fixing ring 14 are limited by the set fixing groove 18 to prevent them from rotating. Then, the hexagonal threaded tube 13 is rotated with the threaded column 11 using a hexagonal sleeve to connect it. Under the push of the spring 12, the two fixing rings 14 bite each other, so that the hexagonal threaded tube 13 can only rotate in the tightening direction but cannot be loosened, so that the hexagonal threaded tube 13 cannot rotate by itself and cause loosening. At the same time, when the hexagonal threaded tube 13 needs to be loosened, a flat The angle screwdriver pushes the left fixing ring 14 to move, or pushes the spring 12, so that the two fixing rings 14 are no longer engaged, so that the hexagonal threaded tube 13 can be rotated, so that the first connecting plate 8 and the second connecting plate 9 are connected together, and the hexagonal threaded tube 13 can be rotated, so that the compression degree of the spring 12 is different, so that the reverse thrust on the second connecting plate 9 is different, so as to adjust the tightness of the right clamp 1 and the left clamp 2, and then when the first tubular joint 3 and the second tubular joint 4 are connected, the fixing tightness of the first tubular joint 3 and the second tubular joint 4 can be adjusted, so as to achieve the comprehensive tightness of the right clamp 1 and the left clamp 2. The effect of adjusting the degree of tightening makes it possible for the right clamp 1 and the left clamp 2 to be connected no longer limited by the elastic force of the spring 12 when the first tubular joint 3 and the second tubular joint 4 are connected. The spring 12 can be squeezed manually to change the tightness of the right clamp 1 and the left clamp 2. When the elastic force of the spring 12 does not meet the requirements due to the production or use environment, the user can adjust the tightness of the spring 12 to avoid loosening of the right clamp 1 and the left clamp 2 due to insufficient elastic force of the spring 12. When loosening occurs, the spring 12 can tighten the right clamp 1 and the left clamp 2 again to prevent leakage, which is more practical.
