Detailed Implementation

[0017] 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.

[0018] like Figures 1 to 3 As shown in the figure, this embodiment specifically discloses a corrosion-resistant seamless steel pipe, including a seamless steel pipe body 1, an outer moisture-proof sleeve 2 fixedly mounted on the outer side of the seamless steel pipe body 1, and a moisture-absorbing cotton 3 disposed between the outer moisture-proof sleeve 2 and the seamless steel pipe body 1.

Each limiting component 7 includes a fixing block 71, a telescopic rod 72, and a wedge block 73. Fixing blocks 71 are fixedly installed on both the upper and lower sides of one end of the seamless steel pipe body 1. A convex groove 74 is formed within the fixing block 71. A protrusion 64 is slidably disposed within the convex groove 74. The front and rear sides of one side of the protrusion 64 are fixedly connected to the convex groove 74 via the telescopic rod 72. A spring is fitted onto the telescopic end of the telescopic rod 72. 75. One end of spring 75 is fixedly connected to protrusion 64, and the other end of spring 75 is fixedly connected to the telescopic end of telescopic rod 72. The locking claw 62 passes through and engages with the convex groove 74. Grooves 76 are provided on both the front and rear sides of protrusion 64. Wedge block 73 is located within the groove 76 and is fixedly connected to the groove 76 via thrust spring 77. Limiting grooves 78 are provided on both sides of the middle of fixing block 71. One side of the limiting groove 78 communicates with the outside. Wedge block 73 is inserted into the limiting groove 78 and engages with the protrusion 64. When the limiting groove 78 engages, flange 5 continues to drive snap-fit ​​connector 61 to move to the right via connecting rod 63. Snap-fit ​​connector 61 pushes protrusion 64, causing snap-fit ​​claw 62 to move into the interior of convex groove 74. Snap-fit ​​claw 62 changes from an open to a closed state, at which point snap-fit ​​claw 62 engages with snap-fit ​​connector 61 and clamps it. When groove 76 corresponds to limiting groove 78, under the action of thrust spring 77, wedge block 73 moves from groove 76 into limiting groove 78, thereby enabling the protrusion 64 to engage with the snap-fit ​​connector 61. 4. Limiting: When disassembly is required, push the wedge block 73 into the groove 76 within the limiting groove 78. Under the action of the thrust spring 77, move the protrusion 64 to the left within the convex groove 74. The protrusion 64 drives the locking claw 62 to move to the left, allowing the locking claw 62 to move out within the convex groove 74. Under the action of the torsion spring, the locking claw 62 can automatically open, thus separating the locking connector 61 from the locking claw 62, enabling disassembly and separation of the flange 5 from the seamless steel pipe body 1.

[0020] The limiting component 7 is connected to the flange 5 via a snap-fit ​​component 6. The snap-fit ​​component 6 includes a snap-fit ​​connector 61, snap-fit ​​claws 62, and a connecting rod 63. The flange 5 is fixedly connected to the snap-fit ​​connector 61 via the connecting rod 63. One end of the snap-fit ​​connector 61 is provided with a protrusion 64. Both the front and rear sides of the protrusion 64 are connected to the snap-fit ​​claws 62 via torsion springs. The snap-fit ​​connector 61 is located between the two snap-fit ​​claws 62 and cooperates with them. One end of the protrusion 64 is connected to the limiting component 7. Under the action of the torsion spring, the two snap-fit ​​claws 62 can be in an open state. The flange 5 drives the snap-fit ​​connector 61 to move to the right via the connecting rod 63, so that the snap-fit ​​connector 61 and the upper end of the protrusion 64 are connected and located between the two snap-fit ​​claws 62. The limiting component can make the two snap-fit ​​claws 62 lock the snap-fit ​​connector 61, thereby fixing the snap-fit ​​connector 61 and fixing the flange 5 to the seamless steel pipe body 1, so that the flange 5 and the seamless steel pipe body 1 are sealed together.

[0021] A connecting component 8 is provided at the other end of the seamless steel pipe body 1. The connecting component 8 includes a support block 81, a connecting block 82, and a bolt 83. Support blocks 81 are fixedly installed on both the upper and lower sides of the seamless steel pipe body 1. A flange 9 is fixedly installed on one side of the connecting block 82. A through hole 810 is opened on one side of the connecting block 82. A limiting hole 84 is opened on one side of the support block 81. A screw hole 85 is opened on the other side of the support block 81. The screw hole 85 communicates with the limiting hole 84. The bolt 83 is connected to the screw hole 85 by internal thread. The end of the bolt 83 is inserted into the limiting hole 84 and can move along the limiting hole 84. Moving grooves 86 are opened inside both ends of the connecting block 82. Through grooves 87 are opened on both sides of the connecting block 82. Through grooves 87 communicate with the moving grooves 86. A T-shaped rod 88 is slidably installed inside the moving groove 86. One end of the T-shaped rod 88 is inclined and passes through... The through groove 87 is inserted into the corresponding limiting hole 84. The other end of the T-shaped rod 88 is fixedly connected to the inner wall of the moving groove 86 by a spring 89. In use, the present invention is placed in a ventilated place, so that the connecting block 82 is located between the two support blocks 81. Under the action of the spring 89, one end of the T-shaped rod 88 can be pushed through the through groove 87 and inserted into the corresponding limiting hole 84, which can support the connecting block 82 and thus fix the flange 2 9. When it is necessary to remove the flange 2 9, the user rotates the bolt 83. The end of the bolt 83 is inserted into the limiting hole 84 and pushes the T-shaped rod 88 to move to the through groove 87. The T-shaped rod 88 no longer supports the connecting block 82, and the flange 2 9 can be removed. This makes the present invention easy to install and disassemble, and facilitates connection with other seamless steel pipe bodies 1.

[0022] The inner wall of the seamless steel pipe body 1 is bonded with a polytetrafluoroethylene (PTFE) plastic tube 4, and glass fiber is embedded and inlaid on the outer wall of the PTFE plastic tube, so that the PTFE plastic tube 4 is tightly and firmly connected to the seamless steel pipe body 1, thereby making the seamless steel pipe body 1 corrosion resistant. After assembly, the connection can be reinforced to avoid breakage during the support process and improve the service life of the seamless steel pipe body 1.

[0023] Working principle:

[0024] Flange 5 continues to move the snap-fit ​​connector 61 to the right via connecting rod 63. Snap-fit ​​connector 61 pushes the protrusion 64, causing the snap-fit ​​claw 62 to move into the convex groove 74. The snap-fit ​​claw 62 changes from an open to a closed state, at which point it engages with and locks the snap-fit ​​connector 61. When the groove 76 aligns with the limiting groove 78, the thrust spring 77 pushes the wedge block 73 from the groove 76 into the limiting groove 78, thus limiting the protrusion 64. When disassembly is required, the wedge block 73 is pushed from the limiting groove 78 into the groove 76. Under the action of the thrust spring 77, the protrusion 64 moves to the left within the convex groove 74, causing the snap-fit ​​claw 62 to move to the left. The movement allows the locking claws 62 to move out of the convex groove 74. Under the action of the torsion spring, the locking claws 62 automatically open, separating the locking connector 61 from the locking claws 62 for disassembly. This allows the flange 5 to separate from the seamless steel pipe body 1. Under the action of the torsion spring, the two locking claws 62 are in an open state. The flange 5, through the connecting rod 63, moves the locking connector 61 to the right, so that the locking connector 61 is connected to the upper end of the protrusion 64 and positioned between the two locking claws 62. The limiting component allows the two locking claws 62 to lock the locking connector 61, thereby fixing the locking connector 61. This, in turn, fixes the flange 5 to the seamless steel pipe body 1, making the flange... The 1.5 is sealed to the seamless steel pipe body 1. When using this utility model, place it in a ventilated area so that the connecting block 82 is located between the two support blocks 81. Under the action of the spring 89, one end of the T-shaped rod 88 can be pushed through the through groove 87 and inserted into the corresponding limiting hole 84, which can support the connecting block 82 and thus fix the flange 2 9. When it is necessary to remove the flange 2 9, the user rotates the bolt 83. The end of the bolt 83 is inserted into the limiting hole 84 and pushes the T-shaped rod 88 to move to the through groove 87. The T-shaped rod 88 no longer supports the connecting block 82, and the flange 2 9 can be removed. This makes the utility model easy to install and remove. This design facilitates connection with other seamless steel pipe bodies 1. The inner wall of the seamless steel pipe body 1 is bonded with a polytetrafluoroethylene (PTFE) plastic tube 4, and glass fiber is embedded and inlaid on the outer wall of the PTFE plastic tube, so that the PTFE plastic tube 4 is tightly and firmly connected to the seamless steel pipe body 1, thereby making the seamless steel pipe body 1 corrosion resistant. After assembly, the connection can be reinforced to avoid breakage during the support process and improve the service life of the seamless steel pipe body 1. By setting an outer moisture-proof sleeve 2 and moisture-absorbing cotton 3, the seamless steel pipe body 1 can be protected to prevent it from contacting external rainwater and to prevent corrosion caused by prolonged contact with water, which would affect the use of the seamless steel pipe body 1.
