[0002] Flange, also known as flange flange or flange, is a part that connects pipes to each other. It is used for connecting pipe ends. It is also used as flange on equipment inlet and outlet to connect two equipments. Flange has a wide range of applications. For example, the nozzle used in fire trucks needs to use flange to connect pipes.

[0003] The existing flanges for connecting pipes are mostly locked by inserting multiple locking bolts at equal intervals on the side walls of the flanges during use. Since the locking bolts need to pass through the through holes on the two flanges, the through holes on the two flanges need to be aligned during the process of connecting the two flanges before the locking bolts can be inserted. The alignment of the through holes on the two flanges is time-consuming and laborious, which greatly reduces the installation efficiency of the flanges during installation.

[0004] Therefore, in order to solve the above problems, the utility model proposes a flange structure with a positioning structure. Utility Model Content

[0010] Preferably, one side of the two guide rods is fixedly connected with a blocking block.

[0011] Compared with the prior art, the utility model has the following beneficial effects: a spring, a fixed rod, a guide rod, a rotating rod and an extrusion wheel, etc. are provided. When the nozzle used in the fire truck needs to be connected, the two fixed rods can be rotated first. The rotation of the two fixed rods will cause the various mechanisms to be linked. At this time, the guide rod is connected to the fixed rod, so that the guide rod guides the connection of the two flanges, making it easier for the bolts to penetrate the two flanges, thereby improving the connection efficiency of the fire truck nozzle.
