Detachable reusable hose connector and fire hose

Abstract

The invention discloses a detachable reusable hose connector and a fire hose. The hose connector comprises a connector body, a control button movably arranged on the connector body, a lock control ring arranged in a sliding manner and a traction mechanism arranged between the control button and the lock control ring and used for controlling the lock control ring to move, and a convex ring is arranged on the lock control ring. The connector body comprises an outer pipe arranged outside the hose in a sleeving manner and an inner pipe used for being inserted into the hose, the outer end of the inner pipe evenly extends outwards in the circumferential direction to form a plurality of elastic positioning teeth, the outer side walls of the elastic positioning teeth are sleeved with inner extrusion sealing rings, and the control button is adjusted to enable the lock control ring to have a locking position and an unlocking position. When the lock control ring is located at the locking position, the convex ring abuts against the inner side walls of the elastic positioning teeth, when the lock control ring is located at the unlocking position, the convex ring is separated from the inner side walls of the elastic positioning teeth, two hose bodies can be rapidly connected or detached by rotating the control button, the hose connector is arranged, the length of the hose can be rapidly changed, and the hose connector is suitable for various fire fighting occasions. The hose connector can be repeatedly used.

Description

technical field [0001] The invention relates to a detachable reusable hose joint and a fire hose. Background technique [0002] The hoses in the prior art usually need to be fixedly connected to the pipe fittings, and the connection between the hoses also needs to be realized through the hose joints fixed on the hoses. The connections between the hoses and the pipe fittings and between the hoses The connection is fixed by professional equipment by binding or winding steel wires. In this way, the hoses are not easy to disassemble, so that the length of the hose cannot be changed according to actual needs. Forcible removal will damage the joint and reduce the hose. Tightness, reducing the service life of hoses and hose fittings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a detachable and reusable hose joint. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by ...
