Description

Technical Field

[0001] The utility model relates to the technical field of spiral corrugated pipes, in particular to an inner rib reinforced spiral corrugated pipe. Background Art

[0002] Spiral corrugated pipe has a wavy outer surface. It is usually made by curling a metal sheet into a spiral shape and welding it. The wavy shape of the spiral corrugated pipe can increase the flexibility and load-bearing capacity of the pipe, enabling it to adapt to a certain degree of pressure and deflection. Spiral corrugated pipes are often used in industry and construction to transport substances such as gas, liquid and powder. Its wavy shape can increase the internal space and improve the strength and stability of the pipe. Spiral corrugated pipes can be used in various applications, such as HVAC systems, heat exchangers, fans and exhaust systems.

[0003] However, the existing internal rib reinforced spiral corrugated pipes are often installed by means of clamping or bonding. Due to the influence of thermal expansion and contraction of weather temperature, the spiral corrugated pipes may be deformed to a certain extent, thereby affecting the connection effect between the spiral corrugated pipes and reducing the sealing and connectivity.

[0025] The fixing ring 31 is fixedly mounted on the surface of the spiral bellows 1, a fixing block 32 is fixedly mounted on the inner side of the fixing ring 31, a swivel 33 is rotatably connected to the surface of the spiral bellows 1, the swivel 33 is rotatably connected to the inner side of the fixing block 32, a sliding rod 34 is slidably connected inside the swivel 33, a sliding plate 35 is fixedly mounted on the surface of the sliding rod 34, the sliding plate 35 is slidably connected to the surface of the swivel 33, a sealing rod 36 is fixedly mounted on the outer side of the sliding rod 34, the sealing rod 36 is slidably connected to the inside of the fixing block 32, the sealing rod 36 passes through the fixing ring 31, a fixing plate 37 is fixedly mounted on the outer side of the sealing rod 36, a sealing ring 38 is fixedly mounted on the surface of the fixing plate 37, when the sealing ring 38 moves, it will fit on the surface of the connection between the two sections of the spiral bellows 1, thereby improving the sealing and connection effect of the spiral bellows 1, and a fixing part 39 for strengthening the connection effect of the spiral bellows 1 is also provided inside the swivel 33.

[0026] The fixing member 39 comprises: a connecting ring 391, which is fixedly mounted on the inner side of the rotating ring 33, a fixing rod 392 is fixedly mounted on the inner side of the connecting ring 391, a sliding rod 393 is slidably connected inside the fixing rod 392, a fixing spring 394 is fixedly mounted on the surface of the sliding rod 393, the fixing spring 394 is fixedly mounted on the outer side of the fixing rod 392, one end of a torsion spring 395 is fixedly mounted on the inner side of the fixing rod 392, and the other end of the torsion spring 395 is fixedly mounted on the inner side of the connecting ring 391. After the insertion is completed, the spiral bellows 1 can be pulled outward. When the spiral bellows 1 is pulled outward, the inner rib 2 will pull the fixing rod 392 to move away from the surface of the spiral bellows 1, and during the movement of the fixing rod 392, since a groove 3910 is provided inside the connecting ring 391, for this purpose, the fixing rod 392 is movable When it moves to a vertical angle, it will be resisted by the groove 3910 opened inside the connecting ring 391, thereby restricting the fixed rod 392, and the sliding rod 393 will also be reset under the action of the fixing spring 394, thereby being inserted into the surface of the spiral bellows 1 for restriction, thereby improving the stability and fixity of the connection of the spiral bellows 1, and improving the convenience of the spiral bellows 1 when in use. There are three groups of sealing assemblies 3, and the three groups of sealing assemblies 3 are arranged in a circular array with the center point of the spiral bellows 1 as the center point. An arc groove 330 is opened on the surface of the rotating ring 33, and the arc groove 330 on the surface of the rotating ring 33 can be used to resist the sliding rod 34 to drive the movement of the sealing rod 36. A groove 3910 is opened on the inner side of the connecting ring 391, which can restrict the fixed rod 392 and limit the inner rib 2 on the surface of the spiral bellows 1.

[0027] When sealing the installation connection between the spiral bellows 1, the two sections of the spiral bellows 1 can be plugged in.
