[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A flange structure that is easy to assemble and disassemble includes a left end pipe and a right end pipe. A flange plate one is fitted onto the surface of the left end pipe, and a flange plate two is fitted onto the surface of the right end pipe. Four positioning components are fixedly connected to one side of the flange plate two. A lower clamping ring is fitted onto the surface of the flange plate one, and an upper clamping ring is rotatably connected to one end of the lower clamping ring. A support base is fixedly connected to one side of the lower clamping ring, and a tension component is rotatably connected to the inner side of the support base. The positioning components include a positioning rod fixedly connected to one side of the flange plate two, a telescopic rod slidably connected inside the positioning rod, and a support spring fixedly connected to one end of the telescopic rod. The tension component includes a rotating frame rotatably connected to the inner side of the support base, a rotating sleeve rotatably connected to the inner side of the rotating frame, and a pull ring threadedly connected to the middle of the rotating sleeve.

[0007] As a further embodiment of this utility model: the surface of the flange is provided with a positioning hole that matches the positioning rod, and a buckle is fixedly connected to one side of the upper clamping ring. The buckle serves to cooperate and connect with the pull ring.

[0008] As a further embodiment of this utility model: a sealing sleeve is fitted inside one end of the left end tube, and a sliding sleeve is inserted into one side of the sealing sleeve. The sliding sleeve enhances the sealing performance when subjected to vibration.

[0009] As a further embodiment of this utility model: one end of the sliding sleeve is fixedly connected to several sets of telescopic springs in a circular array, and one end of each telescopic spring is fixedly connected to a support ring. The support ring serves to support the telescopic spring.

[0010] As a further embodiment of this utility model: a connecting sleeve is sleeved on the surface of the support ring, and the connecting sleeve is sleeved inside the right end tube. The connecting sleeve serves to connect to and support the inside of the right end tube.

[0011] As a further embodiment of this utility model: a sealing gasket is fitted onto the surface of the left end tube, and a groove adapted to the sealing gasket is provided on one side of the flange. The groove facilitates the insertion of the sealing gasket and reduces wear.

[0012] As a further aspect of this utility model: two sets of sealing rings are fitted onto the surface of the sliding sleeve. The sealing rings are made of rubber, and the sealing rings enhance the sealing performance.

[0013] The beneficial effects of this utility model are:

[0014] 1. This easy-to-assemble and disassemble flange structure, through the setting of a tension component, a lower clamping ring, and an upper clamping ring, allows for easy disassembly and assembly of pipes by pushing the rotating frame when disassembly is required. The rotating frame rotates on the support base, and the rotating sleeve rotates inside the rotating frame, causing the rotating sleeve to push the pull ring, which disengages from the buckle. This, in turn, pulls the upper clamping ring, causing it to rotate and open at one end of the lower clamping ring. This achieves the effect of easy disassembly and assembly of pipes by the flange structure, reducing the number of steps in pipe installation and improving the convenience and installation efficiency of the easy-to-assemble and disassemble flange structure.

[0015] 2. This easy-to-assemble and disassemble flange structure, through the setting of the positioning component, allows for alignment of the left and right end pipes during installation. Then, the positioning rod on flange two is inserted into the positioning hole on flange one for positioning. At the same time, during the installation of the lower and upper clamping rings, the telescopic rod slides under pressure within the positioning rod, and the support spring deforms and contracts under force, thereby achieving a precise positioning effect, ensuring a stable connection of the pipeline, maintaining good sealing performance, and improving the stability of the flange structure.
