[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figures 2 to 4 The utility model provides an embodiment: a connection assembly for an aviation hydraulic pipeline, comprising a second connecting pipe 5, a limiting column 17 is fixedly connected inside the second connecting pipe 5, a slider 18 is slidably connected to the outer wall of the limiting column 17, a plug block 16 is fixedly connected to the outer wall of the slider 18, a spring 19 is fixedly connected to one side of the outer wall of the plug block 16, a second connecting ring 4 is threadedly connected to the outer wall of the second connecting pipe 5, a groove 14 is provided inside the second connecting ring 4, the outer wall of the plug block 16 is slidably connected to the inner wall of the groove 14, the second connecting ring 4 is threadedly connected to the first connecting ring 3, the first connecting ring 3 is slidably connected to the first connecting pipe 1, the outer wall of the first connecting pipe 1 is fixedly connected to a fixing ring 12, and a fixing assembly is arranged on the outer wall of the fixing ring 12; the fixing assembly comprises a limiting block 15, one side of the outer wall of the limiting block 15 is fixedly connected to one side of the outer wall of the first connecting ring 3, the fixing ring 12 is slidably connected to the inner wall of the fixing ring 12, the limiting rod 13 is slidably connected to the inner wall of the limiting block 15.

[0025] Specifically, when it is necessary to connect the hydraulic pipeline, the operator first presses the plug block 16 in both directions. This action causes the slider to slide on the limit column through the interaction between the slider 18 and the limit column 17. Since the plug block 16 is connected to the second connecting pipe 5 through the spring 19, this pressing action will cause the spring to be compressed, thereby pushing the first connecting pipe 1 to move into the second connecting ring 4; when the first connecting pipe 1 is pushed into the second connecting ring 4, the plug block 16 is pushed into the groove 14 by the spring 19, and as the spring is released, the plug block is locked inside the groove to form a stable preliminary connection. At this time, by rotating the first connecting ring 3 and the second connecting ring 4, a further threaded connection can be achieved to ensure the sealing and stability of the connection; the limit rod 13 in the fixing ring 12 interacts with the limit block 15 to achieve the final fixation. The limit block 15 is installed on the outer wall of the first connecting ring 3 and cooperates with the limit rod 13 to prevent the connection from loosening under high pressure or high vibration environment, providing additional safety protection.

[0026] Furthermore, the design of the connection assembly allows for quick and simple operation steps, greatly reducing the time and labor intensity required to install and remove hydraulic lines. This is particularly important for aircraft maintenance, and can improve efficiency during emergency or regular maintenance.

[0027] Reference Figure 2 The outer wall of the first connecting tube 1 is fixedly connected to the first limiting ring 2, and the first limiting ring 2 is provided with a rotating rod 6; the outer wall of the rotating rod 6 is rotatably connected to the first connecting plate 7, and the outer wall of the first connecting plate 7 is provided with a second connecting plate 10; the first connecting plate 7 and the second connecting plate 10 are both provided with a socket 8 inside.

[0028] Specifically, the outer wall of the first connecting tube 1 is fixedly connected with a first limiting ring 2, wherein the first limiting ring 2 is equipped with a rotating rod 6. The setting of the rotating rod 6 allows it to rotate freely in the first limiting ring, and this rotating function enables the first connecting plate 7 connected to the rotating rod to be rotated and adjusted on its axis; the outer wall of the first connecting plate 7 is provided with a second connecting plate 10, and through this layout, the first and second connecting plates can form an expandable connection structure. Each connecting plate is provided with a socket 8 inside, and these sockets are used to insert a fixing rod 9, so as to adjust the relative position of the connecting plate to adapt to different installation requirements; by installing a fixing rod in the socket of the first connecting plate 7 and the second connecting plate 10, the distance and angle between the two connecting plates can be flexibly adjusted. This design allows the pipeline installer to adjust and fix the connecting plate according to the actual pipeline length and direction requirements, ensuring the proper docking and stable connection of the hydraulic pipeline.

[0029] Furthermore, since the design of the connection plate allows the user to make quick adjustments according to specific installation requirements, this simplifies the installation process, reduces maintenance time, and improves maintenance efficiency.

[0030] Reference Figure 3 The outer wall of the insertion hole 8 is threadedly connected with a fixing rod 9, and the outer wall of the second connecting tube 5 is fixedly connected with a first limiting ring 2; a sliding groove is opened inside the second connecting plate 10, and the inner wall of the sliding groove is slidably connected to the outer wall of the rotating rod 6; a threaded hole 11 is slidably connected inside the first limiting ring 2, and the inner wall of the threaded hole 11 is threadedly connected to the outer wall of the rotating rod 6.

[0031] Specifically, the sockets 8 are located on the first connecting plate 7 and the second connecting plate 10, and the outer walls of these sockets are connected to the fixing rod 9 by threads. By rotating the fixing rod, the relative position of the connecting plates can be adjusted to accommodate hydraulic pipelines of different lengths. This design allows the user to flexibly adjust the position of the connecting plates according to the requirements of the installation space and the length of the pipeline; the sliding groove inside the second connecting plate 10 provides a sliding path so that the rotating rod 6 can slide inside it. This design enables the rotating rod to move in the second connecting plate, thereby adjusting the angle and position of the entire connection structure to adapt to different installation conditions; the threaded hole 11 inside the first limiting ring 2 is threadedly connected to the outer wall of the rotating rod 6. This connection method provides an adjustable joint point, allowing the length and tightness of the connection to be fine-tuned by rotating the rotating rod to ensure the stability and sealing of the connection.

[0032] Furthermore, through the threaded connection of the fixing rod and the socket, the user can easily adjust the length and position of the connecting plate, which not only adapts to the requirements of hydraulic pipelines of different lengths, but also facilitates application in complex installation environments.

[0033] Working principle: When it is necessary to use the connection assembly for aviation hydraulic pipelines, first press the plug block 16 in both directions to make the slider 18 slide and connect on the outer wall of the limit column 17. At this time, pressing the plug block 16 can put pressure on the spring 19 connected to the plug block 16, and push the first connecting pipe 1 to the inside of the second connecting ring 4. At this time, the spring 19 will no longer be squeezed, and will rebound, pushing the first connecting pipe 1 to slide the plug block 16 to the inside of the second connecting ring 4 20 for preliminary connection, and further connect the first connecting ring 3 and the second connecting ring 4 by rotating the first connecting ring 3. At this time, slide the first connecting pipe 1 to the inside of the first connecting ring 3, so that the fixing ring 12 and the first connecting ring 3 are just fitted together, and then the first connecting pipe 1 is rotated to connect the limit rod 13 and the limit block 15, so that To achieve a further fixing effect, the above-mentioned design can achieve the effect of quickly connecting the hydraulic pipeline. In order to further fix the hydraulic pipeline, the first connecting plate 7 on the rotating rod 6 is rotated, and the first connecting plate 7 and the second connecting plate 10 are adjusted according to the length of different hydraulic pipelines. By rotating the fixing rod 9 to the inside of the jack 8 in different directions, the length of the first connecting plate 7 and the second connecting plate 10 can be changed, thereby achieving the effect of facilitating adjustment. Then, through the multiple sliding grooves provided on the second connecting plate 10, the sliding groove and the rotating rod 6 are further fixed, thereby achieving the effect of further being able to connect according to the different lengths of the hydraulic pipeline. Through the above-mentioned design, the first connecting pipe 1 and the second connecting pipe 5 are further fixed to prevent them from falling off.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
