Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.
[0022] See also Figure 1-4The utility model provides a technical solution: a leakage-proof right-angle hydraulic pipe joint structure, comprising: a right-angle joint body 1, one end of the right-angle joint body 1 is provided with an external thread 5, by threading the external threads 5 at both ends of the right-angle joint body 1 and the nut structure with the oil pipe 3, the other end of the right-angle joint body 1 is rotatably connected with a nut, the external thread 5 and one end of the nut are connected to the oil pipe 3, the middle outer side of both ends of the right-angle joint body 1 and the end of the oil pipe 3 are fixedly connected with two fixing blocks 6, the outside of the right-angle joint body 1 and the oil pipe 3 are both covered with a protective sleeve 2, which is covered on the outside of the right-angle joint body 1 or the oil pipe 3 by the protective sleeve 2, and the anti-seepage effect of the pipeline connection is completed by the threaded structure, and the corresponding two ends of the protective sleeve 2 are plugged with movable card blocks 11. The interior of the protective sleeve 2 moves to between the right-angle joint body 1 and the oil pipe 3, and the moving blocks 11 at both ends of the protective sleeve 2 are in conflict with the fixed blocks 6. The moving block 11 and the fixed block 6 are snap-fitted together, and the outer sleeve of the moving block 11 is provided with a buffer groove 12. The buffer groove 12 allows the moving block 11 to move inside the buffer groove 12 to play a buffering role. A support spring 7 is fixedly connected between the inner top of the buffer groove 12 and the moving block 11. The moving block 11 conflicts with the support spring 7 for back pressure, completing elastic recovery, and then maintains the limiting effect through the conflict between the right-angle side and the fixed block 6. The top of the moving block 11 is fixedly connected with a pull rod 13, which is pulled outward by the pull rod 13, and the moving block 11 can be recovered inside the buffer groove 12, which is convenient for disassembly and separation of the protective sleeve 2.
[0023] The inner wall of the protective sleeve 2 is fixedly connected to a protective shell 8. During use, the protective shell 8 can protect the connection between the oil pipe 3 and the right-angle joint body 1, and it is not easy to be damaged by bumps. The inner wall of the protective shell 8 is fixedly connected to a thermal insulation layer 9. The thermal insulation layer 9 can insulate the external heat and colder gas. A heating tube 14 is wrapped around the outside of the thermal insulation layer 9. The heating tube 14 can be used to increase the connection with the power supply to provide heat to prevent the pipeline from shrinking due to low temperature. The inner wall of the thermal insulation layer 9 is provided with thermal insulation cotton 10. The internal temperature is insulated by the thermal insulation cotton 10 and the sponge insulation layer 4 to achieve the required temperature control to prevent the problem of thermal expansion and contraction caused by large temperature difference. The middle part of the inner circle of the thermal insulation cotton 10 is fixedly connected to the sponge insulation layer 4.
[0024] Working principle: When in use, firstly, the external threads 5 at both ends of the right-angle joint body 1 and the nut structure are threadedly connected to the oil pipe 3. Before connection, the protective sleeve 2 needs to be sleeved on the outside of the right-angle joint body 1 or the oil pipe 3, and the threaded structure completes the anti-penetration function of the pipeline connection. Then, it moves through the inside of the protective sleeve 2 to between the right-angle joint body 1 and the oil pipe 3, and the moving blocks 11 at both ends of the protective sleeve 2 collide with the fixed block 6. The moving block 11 conflicts with the support spring 7 to return pressure and complete elastic recovery. Then, the limiting effect is maintained through the conflict between the right-angle edge and the fixed block 6. Then, the connected nut structure conflicts with the sponge protective layer 4. Subsequently, during use, the protective shell 8 can protect the connection between the oil pipe 3 and the right-angle joint body 1, and it is not easy to be damaged by collision. Secondly, the thermal insulation layer 9 can insulate the external heat and colder gas, and the internal temperature is insulated by the thermal insulation cotton 10 and the sponge insulation layer 4 to achieve the required temperature control and prevent the problem of thermal expansion and contraction caused by large temperature difference.
