Detailed Description
In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The invention designs a steel pipe snap ring joint for solving the problem of connection between a steel pipe and a hose.
Specific embodiments of the present invention are described below with reference to the accompanying drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Referring to fig. 1-3, a steel pipe snap ring joint comprises an external thread joint 6, a fastener 3 and a split snap ring 4.
In order to realize the quick connection between the steel pipe and the hose.
The male connector 6 is secured to the end of the hose.
In a specific embodiment, the external thread joint 6 comprises a convex ring 8, an external interface 11, an internal interface 10 and an external thread structure 14 matched with an internal thread structure 13 of the fastener 3, the convex ring 8 is arranged at the connecting part of the external thread joint 6 and the hose, the diameter of the external interface 11 is matched with that of the steel pipe body, one end of the internal interface 10 is communicated with the hose channel, and a limiting part 15 is formed between the other end of the internal interface and the external interface 11.
Therefore, in the process of connecting the steel pipe 1 and the external thread joint 6, the whole pipe body is firstly embedded into the external interface 11 and stops extending into the limiting part 15.
In order to improve the sealing performance of the steel pipe 1 and the outer screw joint 6, a gasket 5 is arranged at the limiting part 15, and the steel pipe is tightly pressed with the gasket 5 after being connected with the outer screw joint 6.
In order to prevent the steel pipe 1 from falling off after connection, the outer thread joint 6 is provided with the matched fastener 3 and is matched with the split snap ring 4 to fix the steel pipe 1.
In a specific embodiment, one end of the fastening piece 3 is provided with an open structure 12 for the steel pipe 1 to pass through, the other end of the fastening piece is provided with an inner wire structure 13 connected with the outer wire joint 6, the open snap ring 4 is sleeved on the part of the steel pipe 1 positioned inside the fastening piece 3, and the inner wall of the fastening piece 3 is provided with a conical surface 7 for contracting the open snap ring 4; the tapered surface 7 is formed between the opening structure 12 and the internal thread structure 13.
And under the condition that the steel pipe 1 is connected with the hose 2, the end part of the external thread joint 6 is tightly attached to the split snap ring 4.
