Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as figure 1 with figure 2 As shown, a pipe fastening collar, the collar 1 is a cylindrical ring structure, the diameter of the inner wall 10 of the collar 1 is matched with the outer diameter of the matching pipe 2, and the collar 1 is made of cross-linked polyethylene material with strong shrinkage There is no chamfer structure at the front end of the inner wall of the collar 1; knurl teeth 11 are provided on the inner wall 10 of the collar 1.
[0026] Compared with the existing technology of sliding and tightening pipe fittings, the pipe fitting main body 9 of the present invention is consistent with the prior art, the collar is made of non-metallic material, and the cross-linked polyethylene material itself is a high-temperature and weather-resistant material with high resilience and holding capacity. Tightening force, expansion of more than 15%, retr...
