Specific implementation

[0021] The utility model will be further explained in detail in combination with the drawings and specific implementation.

[0022] As Figs. 1-3 shown, a PE telescopic pipe with multiple adapter nodes comprises several main pipe bodies 1, the main pipe bodies 1 are connected with each other through adapters 2, the main pipe bodies 1 with appropriate length are selected according to actual needs, and the adapters 2 are selected with appropriate specifications according to adapter positions. The main pipe body 1 is a corrugated telescopic pipe, so it has good adaptability, the adapter 2 is provided with a plug-in locking assembly 3 at the joint with the main pipe body 1, and the plug-in locking assembly 3 can quickly connect the main pipe body 1 with the adapter 2 without external fixing parts. The adapter 2 is provided with a sealing assembly 4 linked with the plug-in locking assembly 3, and when the main pipe body 1 is locked with the adapter 2, the sealing assembly 4 also provides sealing compression force.

[0023] Specifically, the adapter 2 has at least two adapter ports 5, and the plug-in locking assembly 3 is arranged in the adapter port 5. The adapter 2 can adopt a straight pipe structure, or select L-shaped, Y-shaped, cross-shaped and other special-shaped structures, and the number of adapter ports 5 is matched with the main pipe body 1.

[0024] Further, the existing locking structure usually adopts a flange plate and a threaded part, which is more complicated to assemble and affects the normal arrangement of the pipeline. The plug-in locking assembly 3 in the embodiment comprises a plug-in barrel 31 arranged at the port of the adapter port 5, the inner side of the port of the main pipe body 1 is tightly pressed against the outer side of the plug-in barrel 31, the adapter 2 has a plurality of locking strips 32 that are centrally symmetrical, the adapter port 5 is provided with a locking sleeve 33, and an extrusion assembly is arranged between the locking sleeve 33 and the locking strip 32.

[0025] Further, the locking sleeve 33 is rotated, the extrusion assembly applies pressure to the locking strip 32 and the main pipe body 1, and then the main pipe body 1 and the adapter 2 are tightly fixed.

[0026] Further, the extrusion assembly is adjusted in a manual mode, which comprises extrusion conical surfaces 34 arranged on the inner side of the locking sleeve 33 and the outer side of the locking strip 32, locking threads arranged between the extrusion conical surfaces 34 for guiding the threaded connection of the locking sleeve 33 and the locking strip 32, and the locking strip 32 is pressed or separated from the main pipe body 1 by rotating the locking sleeve 33. The rotation of the locking sleeve 33 enables the locking sleeve 33 to move axially along the insertion barrel 31, so that the locking strip 32 is tightened to press and fix the end of the main pipe body 1 on the insertion barrel 31.

[0027] In addition, since there is still a gap between the main pipe body 1 and the insertion barrel 31, in order to achieve the gap sealing, the sealing assembly 4 comprises a sealing ring 41 rotatably arranged on the adapter 2, the sealing ring 41 has a plurality of center-symmetrically arranged linkage teeth 42 opposite to the locking sleeve 33, the end of the locking sleeve 33 is provided with linkage openings 43 for the insertion of the linkage teeth 42, the extrusion ring 44 is arranged between the insertion barrel 31 and the locking strip 32, the extrusion protrusions 45 are arranged between the extrusion ring 44 and the sealing ring 41 and are in abutting pressure with each other, and the contact part of the extrusion protrusions 45 has a guide arc surface 46 for guiding the insertion of the extrusion ring 44 into the inside of the main pipe body 1. When the locking sleeve 33 is rotated to the end and drives the sealing ring 41 to rotate circumferentially, the extrusion protrusions 45 further apply extrusion force to make the extrusion ring 44 push and deform the main pipe body 1.

[0028] At the same time, in order to facilitate the rotation, the outer side of the locking sleeve 33 is covered with an anti-skid layer 6, and the anti-skid layer 6 is provided with anti-skid stripes.

[0029] It can be seen that the main pipe body 1 is made of PE material, and the end of the main pipe body 1 opposite to the adapter 2 is provided with a limiting ring 11 which surrounds the circumference, and the limiting ring 11 is in abutting pressure with the end of the locking sleeve 33, so as to further improve the sealing performance.

[0030] Obviously, the outer side of the adapter 2 is provided with a wear-resistant layer 21.

[0031] Preferably, the adapter 2 is made of PU material, which has good corrosion resistance and structural strength, and the elastic modulus can meet the deformation requirement of the locking strip 32 at the adapter interface 5.

[0032] Obviously, the inner side of the main pipe body 1 and the adapter 2 is provided with a reinforcing layer 7. The reinforcing layer 7 makes the inner side of the main pipe body 1 and the adapter 2 have no obvious gap, thereby improving the overall sealing performance of the pipeline system.

[0033] In summary, the principle of the embodiment is that the adapter 2 connects a plurality of main pipe bodies 1, the insertion and locking assembly 3 enables the main pipe body 1 to be inserted into the adapter 2 and axially locked and fixed, and the sealing assembly 4 is linked with the insertion and locking assembly 3 to drive the main pipe body 1 to locally deform and improve the interface sealing performance.
