Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a PVC pipe with a quick installation structure. Background Art

[0002] PVC pipe is a rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic material developed and applied. PVC pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, due to the leakage of PVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C.

[0003] When the existing PVC pipe is butt-jointed and installed, it is usually necessary to first set threads on its surface, and then take the connecting pipe parts with built-in threads for threaded butt joint. After repeated use, the threaded parts of this installation structure are easily damaged and cause thread slippage, and the PVC pipe cannot be rotated after the structure is installed. For this reason, we propose a PVC pipe with a quick installation structure. Utility Model Content

[0025] Combination Figure 1-5As shown, the embodiment of the utility model provides a PVC pipe with a quick installation structure, including: a PVC pipe body 1, and also including: a blocking ring 2 is fixed to the inner wall of the access end of the PVC pipe body 1; an anti-slip groove 3 is also opened at the access end of the PVC pipe body 1, and an internal spring 5 is fixed to the inner bottom surface of the anti-slip groove 3, and an anti-slip steel ball 4 is abutted at the end of the internal spring 5 farther from the anti-slip groove 3, and the anti-slip steel ball 4 is rotatably connected to the top of the anti-slip groove 3; a plug-in convex tube 6 is fixed to the inner wall of the plug-in end of the PVC pipe body 1, and a storage seat 8 is fixed to the outer surface of the storage seat 8, a rubber ring 9 is sleeved inside the storage seat 8, and an anti-slip ring 7 is also fixed to the outer surface of the plug-in convex tube 6.

[0026] It should be noted that: when the PVC tube body 1 is installed quickly, the plug-in end of one PVC tube body 1 is inserted into the access end of the other PVC tube body 1. The plug-in convex tube 6 in the plug-in end of the PVC tube body 1 carries the storage seat 8 and the rubber ring 9, and first enters the access end of the PVC tube body 1. As it continues to go deeper, the storage seat 8 abuts against the blocking ring 2, and the rubber ring 9 fits into the gap between the blocking ring 2 and the storage seat 8. At the same time, the plug-in convex tube 6 carries the anti-slip ring 7 to follow the movement. The anti-slip ring 7 first moves to squeeze the anti-slip steel ball 4 into the anti-slip groove 3, and then the anti-slip ring 7 is separated from the anti-slip steel ball 4. At this time, the anti-slip steel ball 4 is rebounded and reset by the built-in spring 5, and the anti-slip steel ball 4 cooperates with the blocking ring 2 to clamp the storage seat 8, the rubber ring 9 and the anti-slip ring 7, which is conducive to the PVC tube being able to rotate after connection and installation, and avoids long-term threaded connection of the PVC tube, thread damage and slipping damage, thereby increasing the service life of the device;

[0027] Wherein: the anti-slip groove 3 includes: a spring groove 31, a circumferential array is opened at the access end of the PVC pipe body 1, and a built-in spring 5 is fixed on the inner bottom surface of the spring groove 31; a ball groove 32, a circumferential array is opened at the access end of the PVC pipe body 1, and the ball groove 32 and the spring groove 31 are connected to each other in a one-to-one correspondence, and the diameter of the ball groove 32 is smaller than the diameter of the anti-slip steel ball 4;

[0028] Wherein: the diameter of the anti-slip ring 7 is equal to the inner diameter of the PVC pipe body 1, and the outer surface of the anti-slip ring 7 is provided with a circular arc chamfer;

[0029] Wherein: the rubber ring 9 is located between the blocking ring 2 and the anti-slip ring 7, and the outer surface of the rubber ring 9 is in contact with the blocking ring 2;

[0030] Wherein: the diameter of the plug-in convex tube 6 is smaller than the diameter of the blocking ring 2, and the length of the plug-in convex tube 6 is greater than the distance between the blocking ring 2 and the access port of the PVC pipe body 1;

[0031] It should also be noted that: the built-in spring 5 located in the spring groove 31 always supports the anti-slip steel ball 4 in the ball groove 32, so that the above-mentioned anti-slip ring 7 first moves to squeeze the anti-slip steel ball 4 into the anti-slip groove 3, and then the anti-slip ring 7 disengages from and squeezes the anti-slip steel ball 4. At this time, the anti-slip steel ball 4 is rebounded and reset by the built-in spring 5, and the anti-slip steel ball 4 cooperates with the blocking ring 2 to clamp the object seat 8, the rubber ring 9 and the anti-slip ring 7, and the outer surface of the anti-slip ring 7 is provided with an arc chamfer, so that personnel can directly insert or pull out the PVC pipe with force, thereby further improving the installation and disassembly efficiency of the device.

[0032] In the embodiments of the present invention, please refer to Figure 2 and Figure 4 As shown, a fixing ring 13 is fixed on the outer surface of the access end of the PVC pipe body 1, a protective sheet 11 is slidably arranged on the outer surface of the access end of the PVC pipe body 1, an external spring 12 is also sleeved on the outer surface of the access end of the PVC pipe body 1, one end of the external spring 12 is fixed to the fixing ring 13, and the other end of the external spring 12 is in contact with the protective sheet 11, a protective ring 10 is fixed to the plug-in end of the PVC pipe body 1, and the protective sheet 11 can be inserted into the protective ring 10;

[0033] The cross section of the protection sheet 11 is “T” shaped, the cross section of the protection ring 10 is “U” shaped, and the thickness of the long end of the protection sheet 11 is less than the thickness of the protection ring 10 .

[0034] It should be noted that: when the plug-in end of one of the above-mentioned PVC tube bodies 1 is inserted into the access end of the other PVC tube body 1, the protective sheet 11 is inserted into the protective ring 10 of the plug-in end of the PVC tube body 1, and as the insertion continues, the external spring 12 contracts and always pushes the protective sheet 11 back to be located in the protective ring 10, and the protective sheet 11 seals the gap between the two connected PVC tubes, further increasing the sealing performance of the device.

[0035] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
