Quick fire-fighting pipeline joint

Abstract

The invention discloses a quick fire-fighting pipeline joint, and relates to the technical field of fire-fighting equipment. The quick fire-fighting pipeline joint comprises a pipe head, a sleeving device, an inserting device, a reinforcing device and a fastening device, and is characterized in that the sleeving device is installed at the bottom of the pipe head, the inserting device and the reinforcing device are installed in an inner cavity of the sleeving device, and connecting pieces are symmetrically welded to the surface of the pipe head. According to the quick fire-fighting pipeline joint, under the condition that no gap exists between a water pipe and the sleeving device, an adjuster is pulled out of an insertion hole, a fastening ring piece is pressed at the moment, due to the torsional structure, the diameter of the fastening ring piece can be reduced during pressing, two side clamping plates are pulled to be attached to the surface of the sleeving device, finally, clamping teeth are engaged with the surface of a main water pipe and then clamped to an inserting opening, the stability of rapid connection is achieved, at the moment, the fastening ring piece is curled up and connected to the surface of the sleeving device in a sleeving mode, and the wrapping performance of connection between the sleeving device and the water pipe is enhanced again.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a quick fire-fighting pipe joint. Background technique [0002] The water pipe interface is used for the butt connection between the pipes. The existing fire-fighting water pipe joints have the following disadvantages, and the existing fire-fighting water pipe joints are generally directly welded when connected to the fire-fighting water pipe, and this operation causes the joint to be damaged and cannot be replaced in time, and the replacement needs to be connected. The entire water pipe is replaced at the same time, which increases the cost of use. Moreover, if the length of the water pipe is not enough in some fire sources, some fire-fighting water pipe joints cannot be quickly read to connect with water pipes of different calibers and materials, which affects the progress of fire fighting. Invent quick fire-fighting pipe joint for this reason and solve the pro...
