Hose connecting assembly and hose butt joint device

Abstract

The invention discloses a hose connecting assembly and a hose butt joint device. The hose connecting assembly comprises a pipe joint, a sealing ring, an opening gasket and a cylindrical nut, the pipe joint is provided with a sleeve and an inner pipe extending out of the sleeve, a gap allowing a hose to be inserted is formed between the inner pipe and the sleeve, a first chamfer is arranged at the end part of the inner wall of the sleeve, the sealing ring is connected to a position outside the hose in a sleeving mode, the opening gasket is connected to a position outside the hose in a sleeving mode, the first end face of the opening gasket is abutted with the end part of the sleeve so as to abut against the sealing ring into the first chamfer, a plurality of protrusions which are distributed in the circumferential direction are arranged on the second end face of the opening gasket, the cylindrical nut is in threaded connection with the sleeve, the bottom wall of the cylindrical nut is suitable for abutting against the second end face and is provided with a center hole for the hose to penetrate through, and the hole wall of the center hole is provided with a second chamfer suitable for abutting against the protrusions and enabling the free ends of the protrusions to be inserted into the outer wall of the hose. The hose butt joint device comprises the two hose connecting assemblies, wherein the inner pipes of the hose connecting assemblies are connected into a whole and communicate with each other. By the adoption of the scheme, a silica gel ring can be flat and prevented from losing efficacy, and the hose can be locked and prevented from being disengaged.

Description

technical field [0001] The present application relates to the field of pipe connection, in particular to a hose connection assembly and a hose docking device. Background technique [0002] In the prior art, the installation time of the hose connection is long, the efficiency is low, and it cannot be quickly installed, and even PVC glue is required, which makes it impossible to replace it. In the prior art, because the sealing ring is directly locked by the nut, the sealing ring becomes wrinkled and fails. Contents of the invention [0003] The purpose of this application is to overcome the above-mentioned defects or problems in the background technology, and provide a hose connection assembly and a hose docking device, which can ensure that the sealing ring is flat to avoid failure, and can lock the hose to prevent the hose from detaching. [0004] In order to achieve the above purpose, the following technical solutions are adopted: [0005] A hose connection assembly, w...
