Detailed Description

The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

A pipe fitting joint according to a preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings of fig. 1 to 4. The tubular joint can be used to direct a fluid.

Specifically, the pipe fitting joint includes a joint body 10 and at least two pipe connecting assemblies 20. The joint body 10 has at least two mounting passages 101, wherein two of the joint modules 20 are respectively disposed in the two mounting passages 101. Each coupling assembly 20 is configured to interface with a pipe without the need for an annular projection on the end of the pipe.

More specifically, each of the connecting tube assemblies 20 includes a communicating member 21 and a limiting member 22. The communication member 21 has a tubular portion 211, a connecting portion 212 formed by extending from an outer wall of one end of the tubular portion 211 in a radial direction, and a sleeve portion 213 integrally extending from the connecting portion 212 in an axial direction. The sleeve portion 213 is provided coaxially with the tubular portion 211.

After the connecting pipe assembly 20 is installed in the installation channel 101, the stopper 22 is sleeved on the tubular portion 211 and presses the sleeve portion 213. In this way, the communication member 21 is pressed against the mounting passage 101.

The retaining member 22 forms an annular clamping opening 2201 for clamping the pipe body inserted into the installation channel 101. It is worth integrating that, after the pipe body is inserted into the installation channel 101, the pipe body can be clamped in the installation channel 101 because the pipe body is pressed by the annular clamping opening 2201 of the stopper 22.

It is worth integrating, the joint body 10 forms at least one blocking edge 11 in the installation channel 101, so that after each of the communication pieces 21 in the two connecting pipe assemblies 20 is pressed by the limiting piece 22, the end of the communication piece 21 is pressed against the blocking edge 11 to limit the position where the communication piece 21 is installed in the installation channel 101.

It is worth mentioning that the two connecting pipe assemblies 20 are symmetrically mounted on the mounting channel 101 so as to be able to clamp the two pipe bodies.

In the present invention, the tubular portion 211 of the communicating member 21 is hollow, so that after two pipe bodies are clamped to the pipe joint, the two pipe bodies can communicate with each other.

Preferably, the connecting tube assembly 20 further comprises an elastic hoop 23, wherein the elastic hoop 23 is disposed between the communicating member 21 and the retaining member 22. The elastic cuff 23 defines a cinch 2301. In addition, the elastic band 23 has a pressing end 231 and a pressed end 232, wherein the cross-sectional diameter of the pressed end 232 is smaller than the cross-sectional diameter of the pressing end 231, so as to form a guide surface 2301 between the pressing end 231 and the pressed end 232.

When the pipe body is inserted into the installation channel 101, the pipe body passes through the communicating member 21 and is guided by the guide surface 2301 to be clamped in a position between the elastic band 23 and the retaining member 22. Accordingly, the elastic band 23 is unfolded to grip the tube.

More preferably, one end of the retaining member 22 forms a pressing surface 2201 matched with the pressed end 232 of the elastic hoop 23, so that the elastic hoop 23 can be retained between the retaining member 22 and the communicating member 21.

Further, the coupling assembly 20 of the pipe fitting joint further comprises a sealing ring 24, wherein the sealing ring is disposed between the elastic band 23 and the end of the sleeve portion 213 of the communication member 21.

Preferably, the end of the sleeve portion 213 integrally extends to form a pressing edge 214 for pressing the sealing ring 24 disposed between the communication member 21 and the retaining member 22. It is worth integrating that after the pipe body is clamped to the pipe fitting joint, the sealing ring 24 seals between the pipe body and the mounting channel 101 of the pipe fitting joint.

More preferably, the coupling assembly 20 further includes a seal 25. Correspondingly, the inner wall of the limiting member 22 forms an installation groove 2201, wherein the sealing member 25 is installed in the installation groove 2201. When the tube is inserted into the installation channel 101, the seal 25 is tightened against the tube.

Further, the pipe fitting joint further comprises a dust cap 30, wherein the dust cap 30 is pivotally connected to the joint body 30 to cover the opening of the installation channel 101, so as to prevent dust from entering the installation channel 101.

It will be appreciated that the sealing ring 24 and the sealing member 25 provide a double sealing effect against the tubular body, thereby preventing fluid from flowing back through the tubular body.

Referring to fig. 5, in another embodiment of the present invention, the fitting body 10 has three mounting channels 101. Further, the pipe joint includes three of the joint pipe assemblies 20, wherein the three joint pipe assemblies 20 are respectively arranged in the three mounting passages 101. Each coupling assembly 20 is configured to interface with a pipe without the need for an annular projection on the end of the pipe. Preferably, two of the three mounting passages 101 are located on the same straight line to be able to abut two of the pipe bodies on the same straight line, and the other mounting passage 101 is disposed in a direction perpendicular to the other two mounting passages to be able to abut the other pipe body in the perpendicular direction.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
