Laminated plastic steel spiral corrugated pipe has important applications in various engineering and construction projects. Its advantages include corrosion resistance, lightness, and easy installation, making it an ideal choice for many piping systems.

[0003] In some engineering projects, a longer pipe length may be required to cover a larger distance. A single pipe length may not meet the needs of the project, so multiple groups of splicing are required to form the required length. In the prior art, when some laminated plastic steel spiral corrugated pipes are spliced, a connector is generally welded at one end of the connection, and then the splicing is performed through the connector to ensure the stability of the connection of the laminated plastic steel spiral corrugated pipe.

[0004] In the prior art, the connectors used in some laminated plastic steel spiral corrugated pipes are generally plug-in type. When in use, in order to ensure the sealing of the pipe, a sealing ring is sleeved on the outer wall of one part of the connector, and then this part of the connector is inserted into the inner wall of the other part of the connector, and the sealing connection is performed by squeezing the sealing ring. The whole process requires manual installation by workers, and repeated pushing is required to achieve successful installation, which is too time-consuming and labor-intensive. At the same time, the sealing ring may age after long-term use, resulting in loosening of the connection end and too low sealing life. Therefore, a laminated plastic steel spiral corrugated pipe is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figure 1-Figure 2 , Figure 6-Figure 7 The utility model provides an embodiment: a laminated plastic steel spiral corrugated pipe, comprising a pipe body 1, a plug-in pipe 2 is fixedly connected to the right surface of the pipe body 1, and a sleeve pipe 3 is fixedly connected to the left surface of the pipe body 1. The pipe body 1 is a laminated plastic steel spiral corrugated pipe in the prior art, which has the characteristics of corrosion resistance, lightness, and easy installation. It is an ideal choice for many pipeline systems. At the same time, the connection between it and the plug-in pipe 2 and the sleeve pipe 3 is through hot melt welding, which can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A through groove 5 is provided at the front end of the left surface of the sleeve pipe 3. The sleeve pipe 3 The inner wall is provided with a fixing component 4, the inner wall at the front end of the sleeve tube 3 is provided with a through groove 2 9, and the inner wall of the through groove 2 9 is provided with a fastening component 6. When multiple groups of pipes are spliced, the plug-in pipe 2 of one group of pipes can be used in conjunction with the sleeve tube 3 of another group of pipes, which can improve the efficiency of pipe installation and improve practicality. The fixing component 4 includes an arc-shaped connecting plate 44, and the bottom end of the front side and the bottom end of the rear side of the arc-shaped connecting plate 44 are respectively connected to a group of sliders 45 to ensure the synchronization of the structural movement. The arc-shaped connecting plate 44 is slidably connected to the inner wall of the top end of the sleeve tube 3, and the lower surface of the front end of the arc-shaped connecting plate 44 is slidably connected to the inner wall of the through groove 1 5, and the front side of the bottom end of the left surface of the arc-shaped connecting plate 44 is fixedly connected with a slider 45.

[0035] Reference Figure 1 , Figure 5-Figure 7The fastening assembly 6 includes a moving block 62. When the threaded rod 61 is rotated, the moving block 62 will slide on the inner wall of the through groove 29. At this time, the moving block 62 will stretch the spring 2 63 to ensure that it can adjust its tightness, thereby improving the stability of the connection between the multiple groups of pipe main bodies 1. The moving block 62 is slidably connected to the inner wall of the through groove 29. The right surface of the moving block 62 is threadedly connected with a threaded rod 61. The threaded rod 61 is a rod-shaped structure with a thread in the prior art, and its outer wall is provided with a threaded rod. At the same time, it has the characteristic of axial self-locking, which ensures the stability of the structure connected to its outer wall. The right end of the threaded rod 61 is slidably connected to the inner wall of the right end of the through groove 29. The left surface of the moving block 62 is fixedly connected with the spring 2 63. The spring 2 63 itself has a certain elasticity. It always pulls the arc connecting plate 44 to move to the left through its own elasticity, and can assist the multiple groups of pipe main bodies 1 to be spliced ​​through its elasticity. The left end of the spring 2 63 is fixedly connected to the right surface of the bottom end of the front side of the arc connecting plate 44.

[0036] Reference Figure 4 one Figure 6 The inner wall of the slider 45 is elastically connected to the rectangular block 2 46 through a spring 1 47. The spring 1 47 always pulls the rectangular block 2 46 to move backward through its own elasticity to ensure the stability when multiple groups of pipe bodies 1 are connected together. The rectangular block 2 46 is slidably connected to the inner wall of the slider 45. One end of the spring 1 47 is fixedly connected to the inner wall of the slider 45. The other end of the spring 1 47 is fixedly connected to the rear surface of the rectangular block 2 46. The front surface of the rectangular block 2 46 is fixedly connected to the connecting plate 41. The rear surface of the left end of the connecting plate 41 is fixedly connected to a clamping block 48. The clamping block 48 is set to a triangular shape, and its left surface is set to an inclined surface. The set inclined surface can improve the efficiency of assembling multiple groups of pipe bodies 1.

[0037] Reference Figure 1 , Figure 3 The fixing assembly 4 also includes a rectangular block 42, which is fixedly connected to the front surface of the plug-in tube 2. A rectangular groove 43 is provided on the front surface of the right end of the rectangular block 42. The rectangular block 42 is tightly attached to the through groove 5 to ensure the stability of the connection.

[0038] Reference Figure 1-Figure 3 A sealing ring 7 is fixedly connected to the right surface of the plug-in tube 2, and an annular sealing groove 8 is opened on the left surface of the sleeve tube 3. The sealing ring 7 is matched with the annular sealing groove 8 to ensure the stability of the connection.

[0039] Working principle: when in use, when multiple groups of pipe bodies 1 need to be connected, the plug-in tube 2 set on the right surface of one group of pipe bodies 1 can be plugged into the inner wall of the sleeve tube 3 set on the left surface of another group of pipe bodies 1. During the insertion process, it is necessary to ensure that the rectangular block 42 enters the inner wall of the through groove 5. When the rectangular block 42 enters the inner wall of the through groove 5, it will contact the clamping block 48 and push it to move along the inclined surface of the clamping block 48. The clamping block 48 will drive the connecting plate 41 to move. The connecting plate 41 will drive the rectangular block 2 46 to slide on the inner wall of the slider 45 while stretching the spring 1 47 until the clamping block 48 overlaps with the rectangular groove 43. At this time, the spring 1 47 will drive the rectangular block 2 46, the connecting plate 41 and the clamping block 48 to move in the opposite direction through its own elasticity to reset, so that the clamping block 48 will be stuck on the inner wall of the rectangular groove 43, and the two groups of pipe bodies 1 can be spliced. After the splicing is completed, the sealing ring 7 will be inserted into the inner wall of the annular sealing groove 8 to ensure the sealing of the connection between the multiple groups of pipe bodies 1.

[0040] During the installation process, if the volume of the pipe body 1 is too large, it is difficult for the worker to push the plug-in tube 2 into the inner wall of the sleeve tube 3. At this time, the rectangular block 42 can be inserted into a part of the inner wall of the through groove 5, and then the slider 45 can be pushed toward the rectangular block 42 to move so that the block 48 is stuck on the inner wall of the rectangular groove 43. During the pushing process, the slider 45 will drive the arc-shaped connecting plate 44 to move, and the arc-shaped connecting plate 44 will stretch the spring 2 63. When the block 48 is stuck on the inner wall of the rectangular groove 43, the slider 45 can be loosened. At this time, the spring 2 63 will bring the plug-in tube 2 into the inner wall of the sleeve tube 3 through its own elasticity, thereby improving work efficiency. When disassembly is required, the connecting plate 41 can be pulled to release the limit of the block 48. The subsequent structural coordination method is the same as above, which improves practicality.

[0041] After the two groups of pipe bodies 1 are spliced ​​together, the threaded rod 61 can be rotated. At this time, the moving block 62 threadedly connected to the outer wall of the threaded rod 61 will move horizontally. At the same time, the moving block 62 will stretch the spring 2 63, so that the spring 2 63 is in a taut state. In this way, the spring 2 63 will always pull the arc connecting plate 44 through its own elastic reaction force, so that the plug-in tube 2 and the sleeve tube 3 are always tightly pressed together, thereby improving the stability of the connection.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
