A sealing member 1 is arranged on the inner side of the pipe mouth of the socket pipe fitting, including a sealing ring fixed in the inner ring groove. When the pipe is inserted, the sealing ring is squeezed to produce elastic deformation, tightly wrapping the pipe, and achieving a good sealing effect. At the same time, the broken groove design of the inner ring surface of the sealing ring enables the sealing ring to be more easily retracted into the inner ring groove after being compressed, and better wrap the pipe when rebounding, further improving the sealing performance. A protective sleeve is arranged at the outer ring of the pipe mouth of the socket pipe fitting, including a rubber cover and a rubber ring. When the pipe is installed, the rubber cover can be sleeved on the outer side of the connection between the socket tee and the pipe, effectively reducing the erosion of the pipe connection by external rainwater and extending the service life of the pipe fitting. When the socket-and-spigot pipe fitting is in an idle state, the gap between the rubber cover and the sealing gasket can be sealed by sealing parts such as rubber baffles and rubber support rings, which effectively prevents the accumulation of external debris particles or dust, keeps the socket-and-spigot pipe fitting clean and intact, and provides convenience for subsequent use.

DETAILED DESCRIPTION

[0024] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 6 The present invention provides a technical solution: an easy-to-install quick socket pipe fitting, comprising a socket tee 1, wherein the inner sides of the three pipe openings of the socket tee 1 are each provided with a seal 1, wherein the seal 1 comprises a sealing ring 5, wherein the sealing ring 5 is an annular ring, wherein the outer ring surface of the sealing ring 5 is fixed in an inner ring groove 2, wherein the inner ring groove 2 is an annular groove, wherein the inner diameter of the sealing ring 5 is smaller than the inner ring diameter of the inner ring groove 2, wherein the inner ring surface of the sealing ring 5 is provided with a broken groove 6, wherein the broken groove 6 is an annular groove, wherein the outer ring diameter of the broken groove 6 is equal to the inner ring diameter of the inner ring groove 2.

[0026] When in use, after the pipe fitting is inserted into the pipe mouth of the socket tee 1, the sealing ring 5 is squeezed by the inserted pipe to produce elastic deformation. At this time, the sealing ring 5 is compressed and retracted into the inner ring groove 2. The sealing ring 5 rebounds and wraps the inserted pipe, thereby improving the sealing performance of the pipe after being inserted into the socket tee 1, and realizing pre-limiting of the pipe inserted into the inner side of the socket tee 1 to prevent loosening.

[0027] The three pipe openings of the socket tee 1 are provided with internal threads on the inner sides. The internal threads are divided into two sections. The two sections of internal threads are symmetrically distributed about the seal 1. The internal threads include internal thread section 1 3 and internal thread section 2 4. The internal thread section 1 3 and the internal thread section 2 4 are symmetrically distributed about the inner ring groove 2, and the internal thread section 1 3 is located at the pipe opening of the socket tee 1.

[0028] When in use, the internal thread is set into two sections in order to cooperate with the external thread set on the outer wall of the inserted pipe, that is, the pipe is threadedly inserted into the socket tee 1 by screwing and pushing, and the two sections of external thread cooperate with the sealing ring 5 to improve the firmness and sealing of the connection between the pipe and the socket tee 1.

[0029] The three pipe openings of the socket tee 1 are all provided with sealing components 2, which include a sealing gasket 7 and a rubber plug ring 8 integrally formed at the inner ring opening of the sealing gasket 7. The sealing gasket 7 is fixed to the pipe opening end of the socket tee 1, and the rubber plug ring 8 is inserted into the pipe opening of the socket tee 1.

[0030] When in use, after the sealing gasket 7 and the rubber plug ring 8 are installed at the end of the socket tee 1, the pipeline squeezes the rubber plug ring 8 to deform, that is, the rubber plug ring 8 is clamped between the socket tee 1 and the pipeline, thereby improving the sealing performance of the pipeline and the socket tee 1 after connection.

[0031] And protective sleeves are provided at the outer rings of the three pipe openings of the socket tee 1. The outer ring surfaces of the three pipe openings of the socket tee 1 are provided with outer ring grooves 9. The outer ring grooves 9 are annular grooves. The protective sleeves correspond to the outer ring grooves 9 one by one. One end of the protective sleeve is sleeved in the outer ring groove 9. The protective sleeve includes a rubber cover 10. One end of the rubber cover 10 is fixed on the surface of the outer ring groove 9. The rubber cover 10 is an "L"-shaped circular tube in cross section. The inner ring diameter of the other end of the rubber cover 10 is smaller than the pipe opening diameter of the socket tee 1.

[0032] When in use, when it is necessary to insert the pipe into the socket tee 1, it is necessary to first turn the rubber cover 10 outside, at this time the pipe mouth of the socket tee 1 is exposed, after the pipe is screwed to the pipe mouth of the socket tee 1, turn back the rubber cover 10, and the rubber cover 10 is sleeved on the outside of the connection between the socket tee 1 and the pipe to reduce the erosion of the pipe connection by external rainwater.

[0033] A rubber ring 11 is fixed to the other end of the rubber cover 10. The rubber ring 11 is a circular ring structure with a circular cross-section. A sealing member is provided between the other end of the rubber cover 10 and the sealing gasket 7. The sealing member includes a rubber baffle 12. The rubber baffle 12 is a circular piece. The rubber baffle 12 is clamped between the sealing gasket 7 and the rubber cover 10. A rubber support ring 13 is integrally formed on the surface of the rubber baffle 12. The rubber support ring 13 is clamped between the rubber cover 10 and the rubber baffle 12. A pull strip 14 is fixed to the inner ring mouth of the rubber support ring 13.

[0034] When in use, the rubber baffle 12 is installed between the rubber cover 10 and the sealing gasket 7 so that when the socket tee 1 is not installed in the pipeline, that is, when the socket tee 1 is in an idle state, the rubber baffle 12 is inserted between the rubber cover 10 and the sealing gasket 7 to seal the pipe opening of the socket tee 1 and prevent a large amount of external debris particles or dust from accumulating in the socket tee 1.

[0035] The detailed usage process of the easy-to-install quick socket fittings is as follows:

[0036] When the pipe fitting is inserted into the pipe opening of the socket tee 1, the sealing ring 5 is squeezed by the pipe and elastically deformed. The sealing ring 5 is compressed and retracts into the inner ring groove 2, then rebounds and tightly wraps the inserted pipe. This method not only improves the sealing between the pipe and the socket tee 1, but also pre-limits the pipe to prevent loosening through elastic force.

[0037] In cooperation with the external thread of the outer wall of the pipe, the pipe can be pushed in and screwed into the socket tee 1 by screwing. The two sections of internal threads and the sealing ring 5 work together to enhance the connection firmness and sealing between the pipe and the socket tee 1.

[0038] When the pipe is inserted into the socket tee 1, the rubber plug ring 8 is squeezed by the pipe and deformed. The deformed rubber plug ring 8 is clamped between the socket tee 1 and the pipe, further improving the sealing of the connection.

[0039] When installing the pipeline, the rubber cover 10 needs to be turned outward first to expose the pipe opening of the socket tee 1. After the pipeline is screwed to the pipe opening of the socket tee 1, the rubber cover 10 is turned back to be sleeved on the outside of the connection between the socket tee 1 and the pipeline. The rubber cover 10 and the rubber ring 11 work together to reduce the erosion of the pipeline connection by external rainwater.

[0040] When the socket tee 1 is not installed on the pipeline, that is, in an idle state, the rubber baffle 12 can be inserted between the rubber cover 10 and the sealing gasket 7 through the pull rod 14. The rubber baffle 12 blocks the pipe opening of the socket tee 1 to prevent a large amount of external debris particles or dust from accumulating in the socket tee 1.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
