Two-way pipe joint and two-way pipe joint assembly

Abstract

The invention relates to a two-way pipe joint and a two-way pipe joint assembly. The two-way pipe joint assembly comprises the two-way pipe joint and fastening nuts in threaded connection with the two-way pipe joint. At least one connecting sleeve and connecting threads are arranged on a pipe joint body, wherein the connecting sleeves are used for being connected with a connecting pipe in a sleeving manner, and the connecting threads correspond to the connecting sleeves and are used for being connected with the corresponding fastening nuts. The fastening nuts are in threaded connection with the pipe joint body. At least one elastic barb used for achieving elastic deformation when squeezed by the connecting pipe is arranged on the peripheral face of each connecting sleeve in the circumferential direction, the head end of each elastic barb is connected with the corresponding connecting sleeve, and the tail ends of the elastic barbs are inclined towards end openings far away from the sleeves. According to the two-way pipe joint and the two-way pipe joint assembly, the damage of compressing force to a connecting hose can be reduced when the fastening nuts are screwed down, the service life of the connecting pipe is prolonged, and the fastening nuts can be mounted conveniently.

Description

technical field [0001] The invention relates to the technical field of metal joint connection, in particular to a two-way pipe joint and a two-way pipe joint assembly. Background technique [0002] The two-way joint of the trachea is an important connecting part in the connection of the trachea. Most of the connection between the trachea joint and the trachea used in the market currently uses pressure rings, hot-melt, bonding, etc. to fix the trachea and the trachea joint together. These locking methods Because the connection of the air pipe joint is a smooth or grooved cylinder, the locking is not reliable enough. A little force will cause air leakage and the air pipe will fall off, which will cause great safety hazards to the devices and parts connected by the air pipe. 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.

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

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 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 space formed by the barb and the connecting section during the process of compressing the hose by the compression nut , this will cause deformation and damage to the hose. 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 space of the section is large, the locking force required is larger
