Pipe connector and pipe connector assembly

Abstract

The invention relates to a pipe connector and a pipe connector assembly. The pipe connector assembly comprises the pipe connector and fastening nuts in threaded connection with the pipe connector. At least one connecting sleeve used for being connected with a connecting pipe in a sleeving mode and a connecting thread which corresponds to the connecting sleeve and is used for being connected with the corresponding fastening nut are arranged on a pipe connector body. The fastening nuts are connected to the pipe connector body in a threaded mode. At least one elastic barb used for elastic deformation when squeezed by a connected pipe is arranged on the outer circumferential surface of each connecting sleeve in the circumferential direction, wherein the initial end of each elastic barb is connected with the corresponding connecting sleeve, and the tail end of each elastic bard inclines towards an end opening away from the corresponding sleeve. According to the pipe connector and the pipe connector assembly, damage to the connecting flexible pipe by pressing force when the fastening nuts are screwed can be reduced, the service life of the connecting pipe is prolonged, and the fastening nuts can be installed conveniently.

Description

technical field [0001] The invention relates to the technical field of pipe joint connection, in particular to a pipe joint and a pipe joint assembly. Background technique [0002] The trachea joint is an important connection part in the connection of the trachea. Most of the connections between the trachea joint and the trachea used in the market currently use pressure rings, hot-melt, bonding, etc. to fix the trachea and the trachea joint together. These locking methods are due to the The joint connection is a smooth or grooved cylinder, so the locking is not reliable enough. A little force will cause air leakage and trachea fall off, which will cause great safety hazards to the devices and parts connected by trachea. The Chinese patent with the notification number CN203297815U discloses a quick connection joint for pipes, including a hose joint for connecting a hose and a hard pipe joint for connecting a hard pipe. A barb structure is provided, and a threaded structure t...

[0002] The trachea joint is an important connecting part in the connection of the trachea. Most of the connections between the trachea joint and the trachea used in the market currently use pressure rings, hot-melt, bonding, etc. to fix the trachea and the trachea joint together. These locking methods are due to the The joint connection is a smooth or grooved cylinder, so the locking is not reliable enough. A little force will cause air leakage and trachea fall off, which will cause great safety hazards to the devices and parts connected by the trachea.

The Chinese patent with the notification number CN203297815U discloses a quick connection joint for pipes, including a hose joint for connecting a hose and a hard pipe joint for connecting a hard pipe. There is a barb structure, and a thread structure that matches the compression nut is provided on the side of the hose joint close to the connection section. When in use, the hose is set on the connection section, and then the hose is compressed by the compression nut It is fixed on the connecting section, so that the connection between the hose and the joint can be realized, but in order to ensure the sealing performance of the pipe joint, it is necessary to fill the hose with the barb and the space outside the connecting section during the process of compressing the hose with the compression nut In this way, the hose will be deformed and damaged. When the hose is stressed again in the axial direction, it is easy to break the hose and reduce the service life of the hose. When the hose is compressed and deformed, it is necessary to greater locking force
