[0004] The purpose of the utility model is to solve the shortcomings of the existing flanges in the prior art that, during use, long-term use may cause rust between the flanges or adhesion by aging adhesives, resulting in inconvenience in disassembly of the flanges, thereby affecting the efficiency of flange replacement, and to propose a flange that is easy to replace.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flange that is easy to replace includes a first flange plate and a second flange plate. The bottom of the first flange plate and the top of the second flange plate are both provided with a notch groove. The first flange plate and the second flange plate are both provided with a plurality of through holes. The circumferential inner wall of the through hole is provided with a clamping groove. A screw is inserted into the through hole. A spring is sleeved on the outer wall of the screw. After the screw is inserted into the through hole, the spring is located in the clamping groove. A fastening nut is sleeved on the top thread of the screw.

[0007] Furthermore, a sealing gasket is provided between the first flange and the second flange.

[0008] Furthermore, the sealing gasket is provided with a plurality of through holes, and the size of the through holes is adapted to the card slot.

[0009] Furthermore, the two notch grooves form a V-shaped structure.

[0010] Furthermore, the top of the first flange and the bottom of the second flange are both fixedly connected with connecting pipes.

[0011] The beneficial effects of the utility model are:

[0012] 1. The first flange and the second flange are made to spring outwards under the elastic action of the spring, so that the first flange and the second flange bonded by rusted or aged adhesive can be separated conveniently and quickly.

[0013] 2. By inserting the tool into the notch groove, the first flange and the second flange are pried apart, thereby facilitating the removal of the first flange and the second flange, and further facilitating the replacement of the flange. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A flange that is easy to replace includes a first flange 1 and a second flange 2. The bottom of the first flange 1 and the top of the second flange 2 are both provided with a notch groove 3. A tool is inserted into the notch groove 3 to pry the first flange 1 and the second flange 2 apart, thereby facilitating the disassembly of the first flange 1 and the second flange 2. A plurality of through holes 5 are provided on the first flange 1 and the second flange 2. A clamping groove 6 is provided on the circumferential inner wall of the through hole 5. A screw 8 is inserted into the through hole 5. A spring 7 is sleeved on the outer wall of the screw 8. After the screw 8 is inserted into the through hole 5, the spring 7 is located in the clamping groove 6. Under the elastic action of the spring 7, the first flange 1 and the second flange 2 are bounced outward, thereby facilitating the separation of the first flange 1 and the second flange 2. A fastening nut 9 is threadedly sleeved on the top of the screw 8.

[0020] A sealing gasket 4 is provided between the first flange 1 and the second flange 2, and the first flange 1 and the second flange 2 are sealed by the sealing gasket 4. A plurality of through holes are provided on the sealing gasket 4, and the size of the through holes is adapted to the slot 6. The design of the through holes facilitates the passage of the spring 7. The two notched grooves 3 form a V-shaped structure. A connecting pipe 10 is welded to the top of the first flange 1 and the bottom of the second flange 2.

[0021] The working principle of this embodiment: during disassembly, first, unscrew the fastening nut 9, and the first flange 1 and the second flange 2 are bounced outward under the elastic action of the spring 7, thereby facilitating the separation of the first flange 1 and the second flange 2. If the first flange 1 and the second flange 2 have not been separated, insert the tool into the notch groove 3 to pry the first flange 1 and the second flange 2 apart, thereby facilitating the disassembly of the first flange 1 and the second flange 2.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
