Description

Technical Field

[0001] The utility model relates to the technical field of installation structures, in particular to an installation structure for a spiral corrugated pipe. Background Art

[0002] Spiral corrugated pipes are used in engineering materials. Cables are installed inside the corrugated pipes to protect the internal cables. Depending on the place of use, two sets of threaded pipes need to be installed and connected to ensure the use effect of the threaded corrugated pipes. At the same time, the performance of the threaded pipes after installation needs to be guaranteed.

However, the existing mounting structure is relatively simple, and the sealing performance of the installed bellows is poor. External moisture can easily enter the interior of the bellows through the connection, affecting the cables inside the bellows and affecting the performance of the bellows. In view of the shortcomings of the existing technology, we propose an installation structure for spiral bellows to solve the above problems. Utility Model Content

[0021] The embodiment of the utility model discloses a mounting structure for a spiral corrugated pipe.

[0022] According to the attached Figure 1-5 As shown, the bellows body 1 is composed of a first bellows 101 and a second bellows 102. The first bellows 101 and the second bellows 102 are fixedly connected to a mounting ring 2 at one end close to each other. The outer wall of the mounting ring 2 at the second bellows 102 is fixedly connected to a fixing ring 3. The outer wall of the mounting ring 2 at the first bellows 101 is fixedly connected to a first sealing ring 301. The inner annular array of the fixing ring 3 has multiple groups of positioning rods 4. The positioning rods 4 are inserted into the interior of the first sealing ring 301 to position and install the two groups of bellows. To install the bellows 101 and the second bellows 102, first pick up the second bellows 102, and align the multiple sets of positioning rods 4 installed inside the fixing ring 3 with the positioning grooves 302 at the first sealing ring 301, and insert the multiple sets of positioning rods 4 into the positioning grooves 302. At this time, the second sealing ring 6 can be inserted into the first connecting ring 5 to achieve the installation of the two sets of threaded pipes. Subsequently, the welding assembly is used to weld the outer periphery of the connection between the installed second shielding ring 9 and the first shielding ring 8 to achieve the installation and fixation of the two sets of bellows.

[0023] A second connecting ring 7 and a first connecting ring 5 are respectively provided on the periphery of the fixing ring 3 and the first sealing ring 301. The second connecting ring 7 and the first connecting ring 5 are connected to cover the connection between the fixing ring 3 and the first sealing ring 301. A second blocking ring 9 and a first blocking ring 8 are respectively provided on the periphery of the second connecting ring 7 and the first connecting ring 5. The second connecting ring 7 and the first connecting ring 5 are connected to cover the connection between the second connecting ring 7 and the first connecting ring 5.

[0024] The diameter of the first sealing ring 301 is smaller than the diameter of the mounting ring 2, and the diameter of the fixing ring 3 is the same as the diameter of the mounting ring 2. The fixing ring 3 is sleeved on the outer peripheral wall of the first sealing ring 301. The interior of the first sealing ring 301 is provided with multiple groups of positioning grooves 302, and the positioning rod 4 is inserted into the interior of the positioning groove 302. The connection between the first connecting ring 5 and the second connecting ring 7 is located on the right side of the connection between the fixing ring 3 and the mounting ring 2. The connection between the fixing ring 3 and the mounting ring 2 can be shielded by the first connecting ring 5, and the connection between the first shielding ring 8 and the second shielding ring 9 is located on the right side of the connection between the first connecting ring 5 and the second connecting ring 7. The connection between the first connecting ring 5 and the second connecting ring 7 is shielded by the first shielding ring 8, thereby preventing external moisture from entering the interior of the bellows through the connection between the two groups of bellows and affecting the performance of the bellows.

[0025] The second connecting ring 7 is fixedly sleeved on the outer peripheral wall of the fixing ring 3, and the outer wall of the second connecting ring 7 is fixedly connected to the second sealing ring 6. The first connecting ring 5 is fixedly sleeved on the outer peripheral wall of the mounting ring 2 at the first bellows 101. At the same time, the installed second sealing ring 6 is inserted into the inside of the first connecting ring 5, and the two groups of bellows can be sealed through the sealing gasket 303 at the second sealing ring 6, thereby improving the sealing performance of the two groups of bellows after connection and ensuring the use effect of the threaded pipe after installation.

[0026] The second sealing ring 6 is inserted into the inside of the first connecting ring 5, and the sealing gasket 303 is installed on the outer peripheral wall of the second sealing ring 6. The first shielding ring 8 is fixedly sleeved on the outer peripheral wall of the first connecting ring 5, and the second shielding ring 9 is fixedly sleeved on the outer peripheral wall of the second connecting ring 7. The outer diameters of the first shielding ring 8 and the second shielding ring 9 are the same. The two groups of threaded tubes are positioned and installed through multiple groups of positioning rods 4, so that rotation can be avoided when the periphery of the two groups of shielding rings 8 are welded.
