[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] See also Figure 1-Figure 2 and Figure 4-Figure 8 The utility model provides the following technical solutions: a triangular corrugated tube, comprising an outer tube 1, a metal protective shell 4 is fixedly installed at one end of the outer tube 1, a sleeve 2 is fixedly arranged inside the metal protective shell 4, a connecting tube 3 is slidably sleeved inside the sleeve 2, one end of the connecting tube 3 is fixedly connected to an inner tube 6, the metal protective shell 4 comprises a buckle assembly 7, a plurality of sliding rods 76 are slidably connected to both sides of the metal protective shell 4, a plurality of sliding rods 76 are movably connected to the tops of the plurality of sliding rods 76, and the bottoms of the sliding rods 76 are movably connected to the inner tube 6. A second connecting rod 710 is connected, and one end of the inner wall of the second connecting rod 710 is movably connected to the first connecting rod 79, one end of the first connecting rod 79 passes through the side wall of the second connecting rod 710 and is movably connected to a latch tongue 78, the top of the latch tongue 78 is movably connected to a spring 77, the top of the spring 77 is fixedly connected to a top plate 72, the bottom end of the latch tongue 78 passes through the limiting plate 73 and is slidably engaged in a slot at one end of the holder 75, a block 74 is fixedly installed on the inner wall of the slot of the holder 75, and the other end of the holder 75 is fixedly connected to the outer layer tube 1.

[0028] Specifically, when the corrugated pipes are to be butt-jointed and installed, the staff first slides the connecting pipe 3 into the sleeve 2, the right outer tube 1 drives the holder 75 to move into the metal protective shell 4, the holder 75 drives the block 74 to move, the tongue 78 is squeezed by the block 74 to move upward, and while the tongue 78 moves, the spring 77 contracts until the block 74 moves away from the bottom end of the tongue 78, so that the tongue 78 is no longer squeezed by the block 74, and the spring 77 rebounds, and the spring 77 pushes the tongue 78 to move downward, so that the bottom end of the tongue 78 falls into the groove between the block 74 and the holder 75, thereby forming a buckle, so that the staff The bellows can be quickly connected. When the bellows need to be disassembled from each other, the staff first pulls the pull ring 71, and the pull ring 71 drives the sliding rod 76 to move upward, and the sliding rod 76 drives the second connecting rod 710 to move. When the second connecting rod 710 moves, it drives the latch 78 to move upward, so that the bottom end of the latch 78 leaves the groove between the block 74 and the seat 75, thereby releasing the buckle and allowing the staff to quickly disassemble the bellows. This structure is simple and can withstand a certain amount of tension and pressure, thereby maintaining the integrity and stability of the pipeline system, saving time and labor costs, improving installation efficiency, and facilitating maintenance, repair or replacement work.

[0029] See also Figure 3 The inner tube 6 is fixedly installed inside the outer tube 1, and a plurality of steel wires 5 are fixedly installed in a triangle inside the outer tube 1. The outer tube 1 is made of polytetrafluoroethylene high-strength polymer material, and the inner tube 6 is made of polyethylene PE tube.

[0030] Specifically, installing a triangular steel wire 5 inside the outer tube 1 can enhance the strength and durability of the pipeline, improve its pressure resistance and durability, and thus increase its service life. The outer tube 1 is made of polytetrafluoroethylene high-strength polymer material that can resist corrosion from most strong acids, strong alkalis and organic solvents, and has good protective performance. The inner tube 6 is made of polyethylene PE, which can relatively reduce the overall weight of the pipe, which provides great convenience during transportation and installation, while reducing manufacturing costs.

[0031] See also Figure 3 , Figure 5 One end of the sleeve 2 is fixedly connected to an inner layer tube 6 , and a sealing gasket 8 is fixedly installed inside the sleeve 2 .

[0032] Specifically, the staff can connect the inner tube 6 inside the corrugated tube to each other through the sleeve 2 and the connecting tube 3, and the sealing gasket 8 can form a closed barrier at the joint of the sleeve 2 and the connecting tube 3, which can effectively prevent the leakage of gas, liquid or other media, ensure the normal operation of the mechanical equipment, and avoid various problems that may be caused by leakage.

[0033] See also Figure 3-Figure 4 The centers of the inner layer tube 6 and the sleeve 2 are on the same straight line, and the centers of the inner layer tube 6 and the connecting tube 3 are on the same straight line.

[0034] Specifically, when the centers of the pipes are aligned, the installation process becomes simpler and more efficient. This alignment helps reduce stress concentrations and potential mechanical failures, thereby extending the service life of the piping system.

[0035] See also Figure 4-Figure 6 One side of the top plate 72 and the limiting plate 73 is respectively fixedly connected to the inner wall of the metal protective shell 4 , and the other side of the top plate 72 and the limiting plate 73 is respectively fixedly connected to the outer wall of the sleeve 2 .

[0036] Specifically, the top plate 72 is used to provide a force point for the spring 77 to contract and rebound, and the limit plate 73 is used to horizontally limit the latch tongue 78 so that the latch tongue 78 can only move up and down to prevent the position of the latch tongue 78 from being offset.

[0037] See also Figure 7 The block 74 is arranged at an angle, and the bottom end of the latch tongue 78 is arranged to conform to the inclined surface of the top of the block 74 .

[0038] Specifically, the latch tongue 78 can be better moved up and down, making the buckle assembly 7 more stable, thereby improving the overall efficiency and performance of the buckle assembly 7.

[0039] See also Figure 5 The buckle assembly 7 is symmetrically arranged about the central axis of the metal protective shell 4 and has the same height inside the metal protective shell 4 .

[0040] Specifically, it can ensure that the buckle assembly 7 is evenly distributed inside the metal protective shell 4, so that the overall structure is more stable. The equal height allows the metal protective shell 4 to be evenly stressed when subjected to external force, thereby avoiding structural damage caused by stress concentration.

[0041] When the locking nut 75 is in the unlocking state, the locking nut 78 is unlocked and the locking nut 78 is unlocked, and the locking nut 78 is unlocked. When the locking nut 75 is unlocked, the locking nut 78 is unlocked and the locking nut 78 is unlocked. 10 is moved, and while the second connecting rod 710 moves, it drives the latch 78 to move upward, so that the bottom end of the latch 78 leaves the groove between the block 74 and the seat 75, thereby releasing the buckle and allowing the staff to quickly disassemble the corrugated tube. This structure is simple and can withstand a certain amount of tension and pressure, thereby maintaining the integrity and stability of the pipeline system, saving time and labor costs, improving installation efficiency, and facilitating maintenance, repair or replacement work. The installation of a triangular steel wire 5 inside the outer tube 1 can enhance the strength and durability of the pipeline, improve its pressure resistance and durability, and thus increase its service life. The outer tube 1 is made of high-strength polytetrafluoroethylene polymer material that can resist corrosion from most strong acids, strong alkalis and organic solvents, and has good protective performance. The inner tube 6 is made of polyethylene PE, which can make the overall weight of the pipe relatively light, which provides great convenience during transportation and installation, while reducing manufacturing costs.
