[0002] A diesel pipe joint is a connecting tool between diesel pipelines, which is a detachable connection point between pipelines and plays an indispensable and important role in pipe fittings. The connection forms of pipe joints include socket welding or threaded connection, which are mainly used for small-diameter low-pressure pipelines, for parts that need to be frequently installed and disassembled, or for the final adjustment of pipelines using threaded pipe fittings.
[0003] The existing diesel pipe joints have a fixed length and cannot be telescoped. When the reserved length for installation is insufficient or too long, it is impossible to quickly compensate or shorten the length in a timely manner. The solutions are either to extend or cut off the pipeline, or to replace the adapter with an appropriate length, which all bring certain troubles to the connection work of diesel pipes.
[0004] Therefore, those skilled in the art provide a diesel pipe adapter structure to solve the problems raised in the above background technique. Content of the Utility Model

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 to 4 , the embodiments of the present invention provide a diesel pipe adapter structure, including: a central sleeve 1, an isolating ring 2 is fixedly connected to the inner side of the central sleeve 1, and a strainer 3 is fixedly connected to the inner ring of the isolating ring 2;
[0023] Specifically, a strainer 3 is provided inside the central sleeve 1, which can filter and remove impurities from diesel during the process of diesel flowing through.
[0024] An upper adjusting sleeve 5 is installed above the central sleeve 1, and a lower adjusting sleeve 6 is connected below the central sleeve 1. Matching grooves 4 are provided on both the upper and lower end faces of the central sleeve 1. Rubber sealing rings 7 are respectively fixedly connected to the upper and lower ends of the upper adjusting sleeve 5 and the upper and lower ends of the lower adjusting sleeve 6. The matching grooves 4 correspond to the positions of the rubber sealing rings 7, and the sizes of the matching grooves 4 and the rubber sealing rings 7 are matched. An upper connecting sleeve 8 is connected above the upper adjusting sleeve 5, and a lower connecting sleeve 9 is connected below the lower adjusting sleeve 6. Socket slots 10 are provided on the lower end face of the upper connecting sleeve 8 and the upper end face of the lower connecting sleeve 9, and the sizes of the rubber sealing rings 7 and the socket slots 10 are matched;
[0025] Specifically, the connection between the central sleeve 1 and the upper adjusting sleeve 5 and the connection between the central sleeve 1 and the lower adjusting sleeve 6 are achieved through the insertion connection between the matching groove 4 and the rubber sealing ring 7 to realize sealing, and the rotatability of the upper adjusting sleeve 5 and the lower adjusting sleeve 6 is retained. The connection between the upper adjusting sleeve 5 and the upper connecting sleeve 8 and the connection between the lower adjusting sleeve 6 and the lower connecting sleeve 9 are achieved through the insertion connection between the socket slot 10 and the rubber sealing ring 7 to realize sealing, and at the same time, the rotatability of the upper adjusting sleeve 5 and the lower adjusting sleeve 6 is also ensured. Therefore, on the premise of the overall structure being sealed, both the upper adjusting sleeve 5 and the lower adjusting sleeve 6 can rotate independently, so as to adjust the extending and retracting lengths of the upper compensating pipe 11 and the lower compensating pipe 12, achieving the purpose of adjusting the length of the entire adapter structure;
[0026] An upper compensation pipe 11 is connected through the inside of the upper adjusting sleeve 5 and the upper connecting sleeve 8, and a lower compensation pipe 12 is connected through the inside of the lower adjusting sleeve 6 and the lower connecting sleeve 9. Threaded structures are provided on the inner walls of the upper adjusting sleeve 5, the lower adjusting sleeve 6, the inner walls of the upper connecting sleeve 8, the inner walls of the lower connecting sleeve 9, the outer wall of the upper compensation pipe 11, and the outer wall of the lower compensation pipe 12. And between the upper adjusting sleeve 5, the upper connecting sleeve 8 and the upper compensation pipe 11, and between the lower adjusting sleeve 6, the lower connecting sleeve 9 and the lower compensation pipe 12, they are all connected by threaded fit;
[0027] Specifically, the upper compensation pipe 11 and the lower compensation pipe 12 are respectively connected to the inside of the upper connecting sleeve 8 and the upper adjusting sleeve 5, and the inside of the lower adjusting sleeve 6 and the lower connecting sleeve 9 in a threaded through manner. Utilizing the particularity of the threaded structure, when the upper adjusting sleeve 5 is rotated and the upper connecting sleeve 8 remains stationary, the upper compensation pipe 11 will extend or retract. Similarly, when the lower adjusting sleeve 6 is rotated and the lower connecting sleeve 9 remains stationary, the lower compensation pipe 12 will extend or retract. By this means, the length of this diesel pipe adapter structure can be flexibly adjusted, making the entire diesel pipe adapter structure more convenient and faster in application;
[0028] Fixed rods 13 are welded to the outer walls of the central sleeve 1, the upper connecting sleeve 8, and the lower connecting sleeve 9, and connecting rods 14 are fixedly connected to the ends of the fixed rods 13. The fixed rods 13 and the connecting rods 14 connect the central sleeve 1, the upper connecting sleeve 8, and the lower connecting sleeve 9 into a fixed whole, so that the positions of the upper connecting sleeve 8 and the lower connecting sleeve 9 are fixed, thereby ensuring that when the upper adjusting sleeve 5 and the lower adjusting sleeve 6 are rotated, the upper compensation pipe 11 and the lower compensation pipe 12 can be smoothly moved.
[0029] The working principle of the present utility model is:
[0030] According to the actual reserved length, adjust the length of this diesel pipe adapter structure. Rotate the upper adjusting sleeve 5, and the upper compensation pipe 11 can be extended or retracted. If the length is insufficient or too long, then rotate the lower adjusting sleeve 6, and the lower compensation pipe 12 can be extended or retracted. The lengths of the upper compensation pipe 11 and the lower compensation pipe 12 extending out of the upper connecting sleeve 8 and the lower connecting sleeve 9 respectively can be flexibly adjusted, thereby being able to flexibly adjust the total length of this diesel pipe adapter structure corresponding to different installation requirements. After adjustment, connect the ports of the upper compensation pipe 11 and the lower compensation pipe 12 to the diesel pipeline respectively.
