TECHNICAL FIELD

[0001] The present application relates to the technical field of interface, in particular to a convenient disassembly type gas pipeline interface. BACKGROUND

[0002] The gas pipeline is a special pipeline for conveying combustible gas. Due to the complex installation environment of the gas pipeline, the bending pipe interface is usually used to change the turning of the gas pipeline during installation, so as to adapt to the complex installation environment.

[0003] Some existing bending pipe interfaces are usually of a bending pipe structure, and both ends of the bending pipe are provided with threads. A nut is sleeved outside the threads. During use, the bending pipe is butt jointed with the pipeline to be connected. Then, the nut is rotated so that the nut does not completely protrude from the bending pipe and is gradually screwed with the threads on the pipeline to be connected. Through the above operation, the connection between the bending pipe interface and the gas pipeline is realized.

[0004] However, in the above process, when the bending pipe interface is connected with the gas pipeline, the nut needs to be rotated for several turns. Therefore, when the bending pipe interface is disassembled, the nut also needs to be rotated for several turns in the opposite direction. As a result, it is inconvenient to disassemble, which affects the efficiency of subsequent maintenance and replacement. CONTENT OF THE INVENTION

[0026] In use, the end of connecting pipe 2 and the end of elbow 1 are butted, and the corresponding butt block 3 is aligned, then, the turning shell 4 of the end of elbow 1 is moved, so that the butt block 3 on connecting pipe 2 and elbow 1 enters into straight slot 5, then, the turning shell 4 is counterclockwise rotated for a quarter, so that the butt block 3 on connecting pipe 2 and elbow 1 enters into turning slot 6, and finally the butt block 3 on connecting pipe 2 contacts sliding block 8, so that the sliding block 8 compresses the corresponding spring 9, through the above action, the turning shell 4 only needs to be rotated for a quarter, so that the connecting pipe 2 and elbow 1 can be connected, on the contrary, the turning shell 4 only needs to be reversed for a quarter, so that the disassembly can be completed, through the above action, the advantage that the elbow 1 can be conveniently disassembled is realized.

[0027] Please refer to Figures 1-7 , the slide cavity 7 is arranged equidistantly on the inner wall of the rotating groove 6, the side of the rotating shell 4 facing the connecting pipe 2 and corresponding to the position of the slide cavity 7 is provided with a push block 10, the end of the push block 10 facing the rotating shell 4 extends into the rotating shell 4 and the slide cavity 7, the spring 9 is located between the push block 10 and the slide block 8, one end of the spring 9 is fixedly connected with the push block 10, and the other end of the spring 9 is fixedly connected with the slide block 8.

[0028] When the slide block 8 at the innermost side of the rotating groove 6 cannot apply pressure to the butt joint block 3 (for example, the corresponding spring 9 fails), the corresponding push block 10 drives the slide block 8 to move inward, so that in the secondary connection process, with the rotation of the rotating shell 4, the corresponding butt joint block 3 can only move to the position corresponding to the slide block 8 at the previous position (at this time, the corresponding butt joint block 3 will be blocked by the inwardly moved slide block 8), and the rotating path of the rotating shell 4 is reduced, through the above-mentioned action, not only the service life of the elbow pipe 1 is improved, but also the disassembly of the elbow pipe 1 is further facilitated.

[0030] Through the arrangement of the above-mentioned structure, in the process that the push block 10 drives the slide block 8 to move inward, the push block 10 drives the corresponding clamping plate 11 to move synchronously until the clamping plate 11 close to the limiting plate 12 passes the limiting plate 12, at this time, the part of the push block 10 outside the rotating shell 4 completely enters the rotating shell 4, and in the above-mentioned process, since the limiting plate 12 is located between the two clamping plates 11, the push block 10 is fixed at the current position, and then the corresponding slide block 8 can only keep the state of further entering the rotating groove 6, so as to avoid the slide block 8 to move back and affect the butt joint pressure of the connecting pipe 2 and the elbow pipe 1.

[0031] When the butt joint block 3 enters the rotating groove 6, the insertion strip 13 is inserted in the straight groove 5.

[0032] Through the arrangement of the insertion strip 13, the sealing property of the rotating shell 4 is maintained, and foreign objects are prevented from entering the rotating shell 4 to affect the normal work of the rotating shell 4.
