[0001] The utility model relates to the technical field of flanges, in particular to a PE flange sheet structure which is convenient for butt-jointing installation. Background Art

[0002] Any connection parts that are bolted and closed around two planes are generally called "flanges"; PE flange is a plastic flange, mainly used in polyethylene pipe systems. It is a flange product made of high-density polyethylene by extrusion. PE flange is widely used in pipeline systems in the chemical, petroleum, pharmaceutical and other industries due to its low temperature resistance and good impact resistance. It is used to connect gas and liquid pipelines. At present, most flanges on the market are connected by bolts.

[0003] For example, in the prior art, the utility model with announcement number CN215763880U discloses a double flange elbow that is easy to dock and disassemble, including a docking insertion rod, a connection hole and an elbow assembly, wherein the elbow assembly includes: an elbow body; a first connection flange, which is fixed to the right end of the elbow body; a docking insertion rod, which is fixed to the right periphery of the first connection flange; a second connection flange, which is arranged on the right side of the first connection flange; a sealing ring, which is fixed to the left end of the second connection flange; a connection hole, which is opened on the periphery of the second connection flange; and a connecting pipe, which is fixed to the right end of the second connection flange. The double flange elbow that is easy to dock and disassemble adopts the arrangement of the docking insertion rod and the connection hole to facilitate the positioning and installation of the elbow, and the arrangement of the docking insertion rod prevents misalignment during installation, and the arrangement of the limiting ring groove and the sealing ring can play a good sealing role after installation, greatly improving the sealing of the elbow after connection.

[0004] And the prior art, a connecting flange with a bolt fixing position that can be freely adjusted is disclosed in the announcement number CN216923551U.

[0005] However, bolt connection is time-consuming and labor-intensive, and has many parts, is not easy to carry, and has poor practicality. In addition, when the two flanges are connected to each other, the position of the flanges needs to be stabilized manually, otherwise it is difficult to install and has poor convenience. Therefore, we propose a PE flange structure that is convenient for docking installation to solve the above problems. Utility Model Content

[0025] Among them, Figure 4 and Figure 5 As shown, a plurality of slots 4 are formed on one side of the second flange 2 , and the clamping blocks 56 are movably connected to the slots 4 .

[0026] In this embodiment, when in use, by placing the first flange 1 on one side of the second flange 2, when the through hole 3 is aligned, the positioning pin structure 5 passes through the through hole 3 opened in the first flange 1 and is connected to the through hole 3 opened in the second flange 2. At this time, the spring 50 pushes the block 56 until the block 56 is engaged in the groove 58 opened in the second flange 2, so that the connection between the first flange 1 and the second flange 2 can be locked. The overall installation is relatively convenient, the structure is simple, it is easy to carry and operate, and the overall practicality is strong.

[0027] Among them, Figure 5 As shown, the fixing plate 57 matches the size of the groove 58 .

[0028] In this embodiment, when disassembly is required, the block 56 is pushed by the fixing plate 57, and the block 56 will compress the spring 50 and be retracted into the recovery groove 53.
