[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-3 The assembled, weld-free flange structure includes a first pipe 1 and a second pipe 2. A first flange 5 is fitted onto the outside of the first pipe 1, and a second flange 6 is fitted onto the outside of the second pipe 2. One end of the first flange 5 is fixedly connected to several sets of evenly distributed limiting blocks 9, and the other end of the first flange 5 has several sets of evenly distributed slots 14. One end of the second flange 6 is fixedly connected to several sets of evenly distributed limiting blocks 9, and the other end of the second flange 6 has several sets of evenly distributed inserts 12, which are correspondingly arranged with the slots 14. By setting the slots 12 and 14, it is convenient to connect the first flange 5 and the second flange 6 together, so that the first flange 5 and the second flange 6 can be quickly aligned, thereby improving the installation efficiency of this equipment.

[0025] A first magnet 13 is fixedly connected to one end of each set of insert blocks 12 away from the second flange 6, and a second magnet 15 is fixedly connected to each set of slots 14. The first magnet 13 and the second magnet 15 are opposite magnetic poles and attract each other. By setting the mutually attracting second magnet 15 and first magnet 13 on the slots 14 and insert blocks 12, it is beneficial to improve the stability of the connection between the first flange 5 and the second flange 6, and eliminates the need for workers to manually fix the first flange 5 and the second flange 6, which is beneficial to improve the convenience of installation.

[0026] The first flange 5 and the second flange 6 are provided with several sets of evenly distributed threaded holes 8. Each set of threaded holes 8 is threaded with a bolt 3. The output end of the bolt 3 passes through the first flange 5 and the second flange 6 and is threadedly connected to a nut 4. By setting the bolt and nut 4, it is easy to tightly connect the first flange 5 and the second flange 6 together.

[0027] In this embodiment, by providing slots 12 and 14 on the first flange 5 and the second flange 6, it is convenient to connect the first flange 5 and the second flange 6 together, so that the first flange 5 and the second flange 6 can be quickly aligned, which improves the installation efficiency of this equipment. By providing mutually attractive second magnets 15 and first magnets 13 on the slots 14 and the insert 12, it is beneficial to improve the stability of the connection between the first flange 5 and the second flange 6, eliminating the need for manual fixing of the first flange 5 and the second flange 6, which is beneficial to improving the convenience of installation. By providing bolts and nuts 4, it is convenient to tightly connect the first flange 5 and the second flange 6 together.

[0028] Example 2:

[0029] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: both the first flange 5 and the second flange 6 are threadedly connected to a fixing block 7, and the fixing block 7 is provided with a threaded groove 11, the diameter of the threaded groove 11 increasing from left to right; by setting the fixing block 7, it is easy to drive the limiting block 9 to fit tightly with the first pipe 1 and the second pipe 2.

[0030] Each set of limiting blocks 9 has a friction groove 10 on its inner wall. The friction groove 10 is tightly connected to the outer wall of the first pipe 1 and the second pipe 2. The surface of the friction groove 10 is a rough plane, which helps to increase the friction between the limiting block 9 and the surface of the first pipe 1 and the second pipe 2, helps to prevent the first flange 5 and the second flange 6 from falling off, and facilitates the installation and disassembly of the first flange 5 and the second flange 6, thus improving the ease of installation.

[0031] The inner diameter of the first flange 5 and the second flange 6 is the same as the outer diameter of the first pipe 1 and the second pipe 2. After the insert block 12 is inserted into the slot 14, the threaded holes 8 on the surfaces of the first flange 5 and the second flange 6 are aligned. The worker inserts the insert block 12 on the second flange 6 into the slot 14 on the first flange 5, which is conducive to the quick alignment of the first flange 5 and the second flange 6.

[0032] In this embodiment, a fixing block 7 is provided on the outside of the first flange 5 and the second flange 6. By rotating the fixing block 7, the fixing block 7 is threadedly connected to the limiting block 9, which facilitates the limiting block 9 to fit tightly with the first pipe 1 and the second pipe 2. The surface of the friction groove 10 is a rough plane, which helps to increase the friction between the limiting block 9 and the surfaces of the first pipe 1 and the second pipe 2, helps to prevent the first flange 5 and the second flange 6 from falling off, facilitates the installation and disassembly of the first flange 5 and the second flange 6, improves the convenience of installation, and when damaged, it is not necessary to replace the entire pipe, but the first flange 5 and the second flange 6 can be replaced, which helps to reduce the operating cost of this equipment.
