Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a novel civil engineering plumbing pipe connection device, including threaded sleeve 1, threaded inner tube 11 that two symmetries set up is installed through the two-way screw thread rotation of its inner wall in the 1 inner chamber left and right sides of threaded sleeve, two threaded inner tube 11 terminal surfaces dorsad all are fixed with connecting

pipe

2, 2 peripheral limiting plate 5 that are fixed with of connecting pipe, two limiting plate 5 terminal surfaces in opposite directions are fixed with spacing pipe 4 and gag lever post 12 of pegging graft each other respectively, be equipped with screw thread locating lever 7 in spacing pipe 4 and the

gag lever post

12, 1 peripheral location tooth's socket 3 that is fixed with of threaded sleeve, 7 lower extremes of screw thread locating lever rotate install with location tooth's socket 3 location tooth piece 8 of pegging graft.
