However, there are countless and complicated underground pipelines in various large factories, fields and cities, which greatly increases the difficulty of replacing and maintaining pipe joints. Workers usually have to bring many tools to disassemble and install joints; when temporary operations require pipe docking, the complicated disassembly and installation work also greatly reduces work efficiency. In addition, when emergency interruption of liquid in the pipeline is required, the traditional interruption device is expensive and complicated to install. Therefore, quick-release pipe joints have a very large application prospect. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0024] See also Figures 1 to 7 , the present invention provides a technical solution:

[0025] Quick-release pipe connector, including:

[0026] A connecting pipeline comprises a plug-in water pipe 2 and a sleeve water pipe 1. The plug-in water pipe 2 is inserted in the sleeve water pipe 1. An annular groove 1 3 and an annular groove 2 9 are provided on the plug-in water pipe 2. The annular groove 2 9 is closer to the end of the plug-in water pipe 2 than the annular groove 1 3. An O-ring 8 is provided in the annular groove 2 9. The O-ring 8 is a rubber sealing ring. The O-ring 8 is used to block the gap at the connection between the plug-in water pipe 2 and the sleeve water pipe 1 to prevent water leakage at the connection between the plug-in water pipe 2 and the sleeve water pipe 1. A fixed through hole 7 is provided on the sleeve water pipe 1. Two fixed through holes 7 are symmetrically provided on the sleeve water pipe 1. The axial centers of the two fixed through holes 7 are on the same straight line. The plug-in water pipe 2 is away from the end of the sleeve water pipe 1, and its inner diameter gradually decreases. The vertical cross-section of the inner channel of the end is truncated cone-shaped.

[0027] The quick-release assembly comprises a quick-release pin 4, a pin 5 and an anti-slip shaft 6. The quick-release pin 4 comprises a pin rod 42 and a pin head 41. The pin rod 42 and the pin head 41 are integrally formed. A pulling through hole 43 is provided on the pin head 41. The setting of the pulling through hole 43 facilitates the insertion of a cylindrical rod or other tool to pull the pin rod 42. The anti-slip shaft 6 is arranged on the pin rod 42 of the quick-release pin 4. The anti-slip shaft 6 is rotatably connected to the pin rod 42 of the quick-release pin 4. The pin 5 is inserted at the connection between the anti-slip shaft 6 and the pin rod 42 of the quick-release pin 4, so as to realize the rotatable connection between the anti-slip shaft 6 and the pin rod 42. The axial centers of the anti-slip shaft 6 and the pin rod 42 are arranged on a straight line. After the anti-slip shaft 6 and the pin rod 42 are inserted from the fixed through hole 7 on one side of the sleeve water pipe 1 through the annular groove 3 on the plug-in water pipe 2, they are extended from the fixed through hole 7 on the other side of the sleeve water pipe 1. , and then swing the anti-detachment shaft 6 so that the axial center of the pin rod 42 and the anti-detachment shaft 6 are not in the same straight line, and the pin rod 42 is located in the fixed through hole 7 and the annular groove 3, and the pin head 41 cooperates with the anti-detachment shaft 6 to prevent the pin rod 42 from detaching from the fixed through hole 7 and the annular groove 3, thereby fixing the plug-in water pipe 2 and the sleeve water pipe 1. When the axial center of the anti-detachment shaft 6 is rotated to be in the same straight line with the axial center of the quick-release pin 4, the quick-release pin 4 and the anti-detachment shaft 6 are pulled out from the fixed through hole 7 and the annular groove 3, and the fixation of the plug-in water pipe 2 and the sleeve water pipe 1 is released. Because the inner diameter of the plug-in water pipe 2 gradually decreases, the water in the sleeve water pipe 1 flows into the plug-in water pipe 2, and the pressure on the plug-in water pipe 2 gradually increases, and the plug-in water pipe 2 is quickly and automatically ejected from the sleeve water pipe 1, so that the plug-in water pipe 2 and the sleeve water pipe 1 are detached.

[0028] The utility model is used to solve the problem that the traditional pipe joint assembly and disassembly is time-consuming and laborious and requires carrying a lot of tools. When performing field operations and high-altitude operations, it is inconvenient to carry a lot of tools and it is inconvenient to perform operations for a long time. The utility model can effectively improve the efficiency of pipe joint assembly and disassembly; in addition, the utility model also provides feasibility for pipe assembly and disassembly in a small space where tools cannot be used; in addition, when the liquid flow is precisely controlled, emergency flow interruption is sometimes required. At this time, the quick plug can be reassembled with the automation equipment, so that the automation equipment such as the electric push rod can automatically pull out the pin 42 by pulling the pulling hole 43 on the top of the pin head 41 of the quick plug in an emergency to achieve the purpose of quickly disassembling the pipe joint. The automatic equipment that can realize automatic pulling, such as the electric push rod, can be reasonably selected according to the actual usage scenario.

[0029] Working principle: When in use, insert the plug-in water pipe 2 into the sleeve water pipe 1, and align the annular groove 3 with the fixed through holes 7 on both sides. When the annular groove 3 on the plug-in water pipe 2 can be fully seen through the fixed through holes 7 on the sleeve water pipe 1, turn the anti-detachment shaft 6, set the axial centers of the anti-detachment shaft 6 and the pin 42 in a straight line, insert the anti-detachment shaft 6 and the pin 42 from the fixed through hole 7 on one side of the sleeve water pipe 1 through the annular groove 3 on the plug-in water pipe 2, and then insert the anti-detachment shaft 6 and the pin 42 from the other side of the sleeve water pipe 1. The anti-slip shaft 6 is extended out from the fixing through hole 7 on the side, and then the anti-slip shaft 6 is rotated so that the axial center of the pin rod 42 and the anti-slip shaft 6 are not in the same straight line, and the plug-in water pipe 2 and the sleeve water pipe 1 are fixed. When the plug-in water pipe 2 and the sleeve water pipe 1 need to be separated, the anti-slip shaft 6 is reversed to reset the axial center of the anti-slip shaft 6 and the pin rod 42 to be in a straight line, and then the anti-slip shaft 6 and the pin rod 42 are pulled out to release the fixation of the plug-in water pipe 2 and the sleeve water pipe 1, and then the plug-in water pipe 2 and the sleeve water pipe 1 are separated.

[0030] 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.
