The pipe joint is used for the connection between fluid pipe and fluid pressure device such as water valve, in order to solve the problem that the single-layer sealing structure of traditional pipe joint leaks easily, chinese patent with application number 201821456178.7 discloses a pipe joint, including first connecting pipe, the second connecting pipe, sealing washer and fixing device, external connection is realized through fixing device to first connecting pipe and second connecting pipe, and be provided with the sealing washer in the inside space of first connecting pipe and second connecting pipe, thereby realize the double-deck sealed to pipe joint, make pipe joint have good crushing resistance, leakproofness and shock resistance.
However, the technical scheme has the following defects: firstly, the fixing device in the technical scheme comprises a nut and a screw, wherein a first connecting pipe is clamped on a limiting part of the nut, a second connecting pipe is fixedly locked on the nut through the screw, when the water flow direction flows from the first connecting pipe to the second connecting pipe, long-term unidirectional water flow impact can cause abrasion between the screw and the second connecting pipe, so that the pressure resistance of the pipeline joint is reduced, and the water leakage phenomenon occurs, therefore, the installation sequence and the water flow direction must be considered during the installation of the pipeline joint, only a unidirectional installation mode can be adopted, and certain defects exist; secondly, in order to realize firm installation, the first retainer ring and the second retainer ring which are mutually matched are required to be arranged at the ports of the first connecting pipe and the second connecting pipe respectively, so that the connecting pipes are strong in use pertinence and poor in applicability, and batch type standardized production is not facilitated.
Therefore, a novel pipeline joint with an improved structure is provided.
Disclosure of Invention
The utility model provides a novel pipe joint, its main aim at solves above-mentioned problem.
The utility model adopts the following technical scheme:
a novel pipeline joint comprises a pipe body, a connecting cylinder and a fixing piece; two ends of the connecting cylinder are symmetrically provided with a groove; the end part of the pipe body is inserted into the groove and is locked on the connecting cylinder through the fixing piece.
Further, the fixing piece is a sealing sleeve, the inner side wall of the sealing sleeve is sleeved at the end part of the pipe body, and the outer side wall of the sealing sleeve is provided with external threads; the upper side wall of the groove of the connecting cylinder is provided with an internal thread matched with the external thread.
Furthermore, an annular retainer ring is arranged at the end part of the pipe body, and the end part of the sealing sleeve is mutually supported with the annular retainer ring.
Further, a sealing ring which is mutually supported with the pipe body is arranged in the groove.
Furthermore, the end of the pipe body is provided with a limiting flange, and the connecting cylinder is provided with a limiting groove matched with the limiting flange.
Compared with the prior art, the utility model discloses the beneficial effect who produces lies in:
1. the utility model discloses need not to consider the installation order of rivers direction and two body of left and right sides when the installation, only need insert the body and locate the recess of connecting cylinder in, rethread mounting locking can, simple structure, simple to operate to have two-way shock resistance, compressive property and anti-seismic performance are superior, and application scope is wide.
2. The utility model discloses a set up annular retaining ring and limit flange at the body tip for be connected between body and the connecting cylinder more firmly reliable, improve pipe joint's shock resistance effectively.
3. The utility model discloses in the simple structure of each part, the universalization is strong, is favorable to realizing the standardized production of batch formula to have double-deck seal structure, sealing performance is good, has overcome the easy problem of leaking of traditional pipe joint's individual layer seal structure.
