AI Technical Summary

Technical Problem

The existing snap-on grouting pipe connection device is not arranged tightly at the connection parts, which can easily lead to loose structure problems.

Method used

The snap-on polyethylene composite tube connection structure is adopted, and the position between the connecting sleeve and the composite tube is tighter through threaded connection, and the upper locking ring and lower locking ring are used to press the projection. Combined with the elastic action of the locking member, the upper locking ring and lower locking ring are clamped through the locking assembly, thereby making the connection of the composite tube tighter.

Benefits of technology

It effectively solves the problem of insufficiently tight connections, improves the tightness of the composite pipe connection, prevents leakage, and enhances the stability of the overall structure.
