[0002] Hydraulic pipe fittings are composed of fitting bodies, seals, threads, nuts and other components. The function of hydraulic pipe fittings is to connect hydraulic pipelines, transfer hydraulic energy and realize the functions of hydraulic systems. In hydraulic engineering, hydraulic pipe fittings play a key role in connecting, sealing and transmitting pressure.

[0003] In the prior art, when hydraulic energy needs to be transmitted along a curved path, multiple hydraulic pipe joints are usually spliced ​​into a curved path. However, this splicing has great limitations and cannot perfectly adapt to the curve.

[0004] In order to solve the problem of transmitting hydraulic energy along a curved path, the existing technology usually adopts an integrated hydraulic pipe joint. However, this integrated design can only adapt to specific types of curves, and cannot flexibly adapt to different curvatures and angles to meet diverse engineering needs. It is also easily affected by the external environment and causes problems. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a combined hydraulic pipe joint, comprising a main body, the arc surface of the main body is threadedly connected with a locking nut, one end of the main body is fixedly connected to a hose, one end of the hose is fixedly connected to an interface, and one end of the interface is provided with an adjusting device, the adjusting device comprises a rotating rod, the lower surface of the rotating rod is fixedly connected to the interface, the arc surface of the rotating rod is fixedly connected to a rotating shaft, one end of the main body close to the hose is fixedly connected to a fixing rod, the arc surface of the fixing rod is slidably connected to a limiting rod, one end of the limiting rod is rotatably connected to the rotating rod, the arc surface of the limiting rod is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with an adjusting shaft, the arc surface of the adjusting shaft is slidably connected to two connecting blocks, the inner walls of the two connecting blocks are slidably connected to the rotating shaft, and the two connecting blocks are threadedly connected with a fixing nut on the side away from each other.

[0007] The effect achieved by the above components is: when the hydraulic pipe joint needs to be installed and changed to a certain angle, the interface is rotated, and the interface drives the rotating rod on its surface to rotate on the limit rod until it is rotated to the required position, and the fixing nut is rotated until the connecting block tightly clamps the rotating rod and the limit rod.

[0008] Preferably, the arc surface of the rotating rod is provided with a rubber sleeve.

[0009] The effect achieved by the above components is that the rubber sleeve can make the rotating rod and the limiting rod contact better, making them difficult to separate.

[0010] Preferably, a guide rod is fixedly connected to the inner wall of the limit rod, and the arc surface of the guide rod is slidably connected to the inside of the adjustment shaft.

[0011] The effects achieved by the above components are as follows: the guide rod can not only guide the translation of the adjustment shaft, but also limit the adjustment shaft to prevent the adjustment shaft from deviating.

[0012] Preferably, two rubber rings are provided on the sides of the two connecting blocks close to each other.

[0013] The effect achieved by the above components is to increase the direct contact area between the connecting block and the rotating rod and the limiting rod, so that the connection block is fixed more firmly.

[0014] Preferably, an auxiliary device is provided inside the main body, and the auxiliary device includes a circular hole, and the circular hole is opened on the arc surface of the main body, and the inner wall of the circular hole is interference-connected with a safety plug, and the lower surface of the safety plug is fixedly connected with a connecting rod, and the arc surface of the connecting rod is slidably connected with an auxiliary plate, and the upper surface of the auxiliary plate is fixedly connected with a spring, and the other end of the spring is fixedly connected to the safety plug.

[0015] The effect achieved by the above components is: the air pressure squeezes the auxiliary plate to make it move along the connecting rod, the auxiliary plate squeezes the spring, the spring deforms and exerts force on the safety plug, when the air pressure is too high, the spring deformation has the maximum force and separates the safety plug from the main body, thereby achieving the effect of releasing the air pressure.

[0016] Preferably, a handle is fixedly connected to the upper surface of the safety plug.

[0017] The effect achieved by the above components is that the handle can facilitate the staff to manually change the air pressure in the pipe and can also facilitate the installation of the safety plug.

[0018] Preferably, a sealing ring is provided on the inner wall of the circular hole.

[0019] The effects achieved by the above components are: the sealing ring can increase the direct contact area between the safety plug and the main body, prevent pipeline leakage, and play a sealing role.

[0020] In summary, the beneficial effects of this application are:

[0021] In the present application, when a curved path is encountered during the installation of the hydraulic pipe joint, the main body is first connected to the hydraulic pipe, and then the interface is rotated to adjust the angle. While the interface rotates, the rotating rod on its surface will rotate in the limit rod, and while rotating, the limit rod will move along the arc surface of the fixed rod. When the rotating rod rotates, the rotating shaft on its arc surface will drive the adjusting shaft on the limit rod to move on the slide groove on its surface, and the connecting block will also rotate with the rotation until it stops rotating at the required angle. At this time, the fixing nut is rotated, and the fixing nut will squeeze the connecting block until the connecting block tightly clamps the rotating rod and the limit rod and stops rotating, completing the fixation and achieving the deployment of the curved path. The guide rod is provided to guide the translation of the adjusting shaft and to limit the adjusting shaft to prevent the adjusting shaft from deviating.

[0022] In the present application, when the pressure inside the hydraulic pipe is very high, the pressure will push the auxiliary plate to move along the arc surface of the connecting rod. While the auxiliary plate moves, it will squeeze the spring, causing the spring to deform. When the spring deformation reaches the maximum, the safety plug will be squeezed out of the main body, thereby releasing the pressure and preventing the pipe from bursting. The purpose of setting the sealing ring is to increase the direct contact area between the safety plug and the main body, prevent air leakage in the pipeline, and play a sealing role.

The arc surface of the rotating rod 501 is provided with a rubber sleeve 509, and the rubber sleeve 509 can make the rotating rod 501 and the limiting rod 503 better contact and make it difficult to separate. The inner wall of the limiting rod 503 is fixedly connected with a guide rod 510, and the arc surface of the guide rod 510 is slidably connected with the inside of the adjusting shaft 506.

The effect achieved by the above components is to increase the direct contact area between the connecting block 507 and the rotating rod 501 and the limiting rod 503, so that it is fixed more firmly.

[0032] Reference Figure 4 and Figure 5As shown, in this embodiment: the auxiliary device 6 includes a circular hole 61, the circular hole 61 is opened on the arc surface of the main body 1, the inner wall of the circular hole 61 is interference connected with a safety plug 62, the lower surface of the safety plug 62 is fixedly connected with a connecting rod 63, the arc surface of the connecting rod 63 is slidably connected with an auxiliary plate 64, the upper surface of the auxiliary plate 64 is fixedly connected with a spring 65, the other end of the spring 65 is fixedly connected to the safety plug 62, the air pressure will squeeze the auxiliary plate 64 to make it move along the connecting rod 63, the auxiliary plate 64 squeezes the spring 65, the spring 65 deforms to exert a force on the safety plug 62, when the air pressure is too high, the spring 65 deforms to the maximum force and separates the safety plug 62 from the main body 1.

[0033] Working principle: when a curved path is encountered during the installation of the hydraulic pipe joint, the main body 1 is first connected to the hydraulic pipeline, and then the interface 4 is rotated to adjust the angle.
