Abstract

The invention discloses a clamping type internal expanded joint for water hose connection. The clamping type internal expanded joint comprises a male connecting part and a female connecting part, wherein the male connecting part comprises a male connection tube and a locking slip ring, and the female connecting part comprises a female connection tube and a locking retaining ring; the locking retaining ring is separably connected with the locking slip ring, and a detachable annular expanded retainer ring is respectively arranged in the male connection tube and the female connection tube. The clamping type internal expanded joint has the advantages of being simple in structure, long in service life, good in reliability and strong in resistance to pressure and is suitable for the connection of various water hoses.

Description

technical field [0001] The invention relates to a connection device for a fire hose, more precisely, a clip-type internal expansion joint for connecting a hose. Background technique [0002] Cassette joint is a common fire hose joint, which is widely used in fire hose connection. This type of card joint usually includes a male joint and a female joint. The male joint is engaged with the elastic lock inside the female joint. belt to connect. This steel wire hose clamp or steel belt hose clamp exerts external pressure on the fire hose to prevent it from falling off. However, practice has proved that the fixing method of this kind of hose is not ideal, the exposed hose part is prone to wear, and at the same time, the steel wire hose clamp or steel belt hose clamp is prone to loosening, which affects the reliability of the hose connection. Pressure resistance is also poor. Contents of the invention [0003] The present invention mainly solves the technical problems existin...
