[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial devices;

Internal threads are opened on the inner wall of the annular fixing ring, and external threads A and external threads B are respectively opened on the outer walls of connector A and connector B to cooperate with the internal threads.

[0007] Preferably, a plurality of anti-slip strips are annularly and equidistantly arranged on the outer wall of the annular fixing ring.

[0008] Preferably, the cross-section of the anti-slip strip is triangular, and the anti-slip strip is made of flexible rubber material.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] Please refer to Figure 1-6 , the present invention provides a technical solution: a water delivery pipe with fast splicing, including pipe A1 and pipe B4. One end of pipe A1 is provided with connector A2, connector B5 is arranged inside connector A2, and one end of connector B5 is fixedly connected to pipe B4. Fixing components are arranged on the outer walls of connector A2 and connector B5. An annular cavity 14 is opened at one end inside connector B5, and a sealing component is arranged inside the annular cavity 14; among them, through the use of the fixing components, it is convenient to fix connector B5 and connector A2 together, thereby realizing the splicing of pipe A1 and pipe B4, with simple and convenient operation, improving the working efficiency of the splicing of pipe A1 and pipe B4; through the use of the sealing component, it is convenient to seal between connector B5 and connector A2, improving the sealing performance between connector B5 and connector A, and avoiding the phenomenon of water leakage between connector B5 and connector A, thereby ensuring the normal flow of water.

[0024] In the present invention, the fixing component includes an annular fixing ring 3 slidably arranged on the outer walls of pipe A1 and pipe B4. An internal thread 15 is opened on the inner wall of the annular fixing ring 3, and external threads A6 and B7 are respectively provided on the outer walls of connector A2 and connector B5 in cooperation with the internal thread 15; the annular fixing ring 3 is used to connect connector B5 and connector A2 together, thereby splicing pipe A1 and pipe B4 together.

[0025] In the present invention, a plurality of anti-slip strips 8 are annularly and equidistantly arranged on the outer wall of the annular fixing ring 3. Through the use of the anti-slip strips 8, the friction on the surface of the annular fixing ring 3 is increased, and the friction between the outer wall of the annular fixing ring 3 and the operator's hand is increased, avoiding the phenomenon of slipping when rotating the annular fixing ring 3, thereby facilitating the splicing of pipe A1 and pipe B4.

[0026] In the present utility model, the cross-section of the anti-slip strip 8 is triangular, and the anti-slip strip 8 is made of flexible rubber material to improve the flexibility of the anti-slip strip 8, thereby improving the comfort of the annular fixing ring 3.

[0027] In the present utility model, the sealing assembly includes an annular gasket 12 slidably disposed at one end of the annular cavity 14. An annular sealing ring B10 is provided on the inner end surface of the connecting head A2 to cooperate with the annular gasket 12. A plurality of compression springs 13 are evenly disposed between the annular gasket 12 and the annular cavity 14. A plurality of arc-shaped grooves are annularly and equidistantly formed on the inner wall at one end of the annular cavity 14. A semi-circular gasket 11 is provided in the arc-shaped groove. An annular sealing ring A9 is provided on the inner wall of the connecting head A2 to cooperate with the semi-circular gasket 11.

[0028] In the present utility model, a dynamic sealing structure is provided between the annular gasket 12 and the annular cavity 14, and a dynamic sealing structure is provided between the semi-circular gasket 11 and the arc-shaped groove. The annular cavity 14 is filled with hydraulic oil; this prevents the hydraulic oil from leaking between the annular gasket 12 and the annular cavity 14 and between the semi-circular gasket 11 and the arc-shaped groove, thereby ensuring the normal use of the sealing assembly.

[0029] Working principle: When the present utility model is in use, when splicing the pipeline A1 and the pipeline B4, the connecting head B5 is inserted into the connecting head A2, and then the annular fixing ring 3 is rotated. Then, under the action of the external thread A6 and the external thread B7, the annular fixing ring 3 is fixed on the outer walls of the connecting head B5 and the connecting head A2, thereby realizing the fixation of the connecting head B5 and the connecting head A2, and further realizing the splicing of the pipeline A1 and the pipeline B4; among them, when the connecting head B5 is inserted into the connecting head A2, the annular gasket 12 will enter the annular sealing ring B10 and squeeze the annular gasket 12, and then the hydraulic oil in the annular cavity 14 will move, thereby squeezing the semi-circular gasket 11 into the annular sealing ring A9 to achieve sealing between the connecting head B5 and the connecting head A2, improving the sealing performance between the connecting head B5 and the connecting head A, and preventing water leakage between the connecting head B5 and the connecting head A, thereby ensuring the normal flow of water.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
