Description

Technical Field

[0001] This invention relates to the field of hydraulic pipeline technology, and more specifically to a method for preventing hydraulic pipeline joints from becoming loose. Background Technology

[0002] In hydraulic pipelines, connectors are used when connecting the pipelines. Since the hydraulic pressure in the hydraulic pipeline changes repeatedly, the originally tightly connected pipe joints may become loose. In order to avoid this problem, this application proposes a method for preventing hydraulic pipeline connectors from becoming loose. Summary of the Invention

[0003] Therefore, the present invention provides a method for preventing hydraulic pipeline joints from loosening, in order to solve the above-mentioned problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] According to a first aspect of the present invention, a method for preventing the loosening of hydraulic pipeline joints comprises connecting a first pipeline and a second pipeline into a whole by means of connecting pipelines, placing a mounting plate above the connecting pipeline, having a movable rod extending out of the connecting pipeline, the movable rod passing through the mounting plate and engaging fins on the sides of the first pipeline and the second pipeline, wherein when the liquid pressure in the first pipeline and the second pipeline increases, the movable rod can extend outward so that the fins can tighten the first pipeline and the second pipeline to prevent the first pipeline and the second pipeline from loosening.

[0006] Furthermore, the connecting pipe has a connecting chamber inside, and the two ends of the connecting chamber have stepped surfaces. The first pipe and the second pipe are respectively installed at the two ends of the connecting chamber. The movable rod passes through the side wall of the connecting pipe, and there are multiple movable rods.

[0007] Furthermore, the first pipeline has the same structure as the second pipeline, and the outer wall of the first pipeline has a protrusion near the middle position, and the protrusion has a ring structure.

[0008] Furthermore, the fins are installed on the side of the mounting plate facing the connecting pipeline. Each mounting plate has two fins, one end of which is fixed to a fixing rod. The fixing rod is located inside the mounting plate. The fixing rods on the two fins on the same mounting plate are at different heights. A rotating wheel is provided between the two fixing rods. The surface of the rotating wheel and the surface of the two fixing rods are both provided with first teeth, and they mesh with each other so that when the rotating wheel rotates, the two fixing rods can move closer to each other or further away.

[0009] Furthermore, a rotating shaft is fixed to the rotating wheel, and the rotating shaft is coaxial with the rotating wheel. The surfaces of both the rotating shaft and the movable rod are provided with second teeth, and the rotating shaft and the movable rod mesh with each other.

[0010] Furthermore, the fixing rod is connected to the mounting plate by a second spring.

[0011] Furthermore, a sealing strip is provided on the inner wall of the connecting pipe. The edge of the sealing strip is fixed to the inner wall of the connecting pipe, the end of the movable rod rests on the sealing strip, and the sealing strip is elastic so that the sealing strip can bulge towards the inside of the connecting pipe.

[0012] Furthermore, a fixing plate is fixed to the movable rod, and a first spring is provided between the fixing plate and the connecting pipe.

[0013] Furthermore, the movable rod and the fixed plate form a cross-shaped structure, and a cavity that cooperates with it is provided in the connecting pipeline.

[0014] Furthermore, the first pipeline and the second pipeline are threadedly connected to the connecting pipeline.

[0015] The present invention has the following advantages:

[0016] When implementing the technical solution of the present invention, the first pipeline and the second pipeline are tightly connected together by hydraulic push in the first pipeline and the second pipeline, so as to avoid the pipeline from becoming loose after long-term use.

[0017] When high-pressure liquid flows through the pipeline, the high-pressure liquid causes the movable rod to slide, and then the movable rod can move the fins, so that the two fins can move closer to each other, thereby pulling the first pipeline and the second pipeline together. The higher the liquid pressure in the pipeline, the greater the pulling force provided by the two fins, which makes the connection between the first pipeline and the second pipeline more stable.

[0018] When installing this device, the user can install the first pipe and the second pipe at both ends of the connecting pipe. The threaded design makes it easy for the user to install the three together to achieve initial positioning.

[0019] After the device achieves initial positioning, the fins can be used to lock it onto the side of the protrusion. The movable rod allows the fins to provide a greater pulling force to the protrusion as the hydraulic pressure in the connecting pipe increases. This avoids the situation in traditional structures where the hydraulic pressure can easily push open the pipe connection and cause loosening when the hydraulic pressure rises. Furthermore, this device does not require additional external force during use, which simplifies the complexity of the device to a certain extent and reduces its cost. Attached Figure Description

[0026] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 5 As shown, in a first aspect embodiment of the present invention, a method for preventing hydraulic pipeline joints from loosening is provided. A first pipeline 1 and a second pipeline 2 are connected as a whole by a connecting pipeline 3. A mounting plate 5 is placed above the connecting pipeline 3. A movable rod 7 extends out of the connecting pipeline 3, passes through the mounting plate 5, and clamps a fin 6 on the side of the first pipeline 1 and the second pipeline 2. When the liquid pressure in the first pipeline 1 and the second pipeline 2 increases, the movable rod 7 can extend outward so that the fin 6 can tighten the first pipeline 1 and the second pipeline 2 to prevent the first pipeline 1 and the second pipeline 2 from loosening.

[0029] When implementing the technical solution of the present invention, the first pipeline 1 and the second pipeline 2 are tightly connected together by hydraulic push in the first pipeline and the second pipeline 2, so as to avoid the pipeline from becoming loose after long-term use.

[0030] When high-pressure liquid passes through the pipeline, the high-pressure liquid causes the movable rod 7 to slide, and then the movable rod 7 can move the fin 6. The two fins 6 can move closer to each other, thereby pulling the first pipeline 1 and the second pipeline 2 together. The higher the liquid pressure in the pipeline, the greater the pulling force provided by the two fins 6, which makes the connection between the first pipeline 1 and the second pipeline 2 more stable.

[0031] The connecting pipe 3 has a connecting chamber inside, and the two ends of the connecting chamber have stepped surfaces. The first pipe 1 and the second pipe 2 are respectively installed at the two ends of the connecting chamber. The movable rod 7 passes through the side wall of the connecting pipe 3, and there are multiple movable rods 7. The number of movable rods 7 corresponds to the number of mounting plates 5.

[0032] The first pipeline 1 and the second pipeline 2 have the same structure. The outer wall of the first pipeline 1 is provided with a protrusion 4 near the middle position. The protrusion has a 4-ring structure.

[0033] The fins 6 are installed on the side of the mounting plate 5 facing the connecting pipe 3. Each mounting plate 5 has two fins 6. One end of the fin 6 is fixed to the fixing rod 14. The fixing rod 14 is located inside the mounting plate 5. The fixing rods 14 on the two fins 6 on the same mounting plate 5 are at different heights. A rotating wheel 11 is provided between the two fixing rods 14. The surface of the rotating wheel 11 and the surface of the two fixing rods 14 are both provided with first teeth, and they mesh with each other so that when the rotating wheel 11 rotates, the two fixing rods 14 can move closer to each other or further away.

[0034] A rotating shaft 12 is fixedly connected to the rotating wheel 11. The rotating shaft 12 is coaxial with the rotating wheel 11. The surfaces of the rotating shaft 12 and the movable rod 7 are both provided with second teeth, and the rotating shaft 12 and the movable rod 7 mesh with each other.

[0035] The fixing rod 14 is connected to the mounting plate 5 by a second spring 13. The use of the second spring 13 can limit the position of the fixing rod 14 so that when the external force is removed, the fixing rod 14 can return to the initial position.

[0036] A sealing strip 9 is provided on the inner wall of the connecting pipe 3. The edge of the sealing strip 9 is fixed to the inner wall of the connecting pipe 3. The end of the movable rod 7 rests on the sealing strip 9, and the sealing strip 9 is elastic so that the sealing strip 9 can bulge towards the inside of the connecting pipe 3.

[0037] A fixing plate 8 is fixedly connected to the movable rod 7. A first spring 10 is provided between the fixing plate 8 and the connecting pipe 3. The first spring 10 can limit the position of the movable rod 7, so that when the liquid pressure in the connecting pipe 3 disappears, the movable rod 7 can return to the initial position.

[0038] The movable rod 7 and the fixed plate 8 form a cross-shaped structure, and a cavity is provided in the connecting pipe 3 to cooperate with it, so that the movable rod 7 can slide in the cavity, and can stop sliding when it slides to a predetermined position (at this time, the sealing strip 9 is attached to the inner wall of the connecting pipe 3).

[0039] The connection method between the first pipe 1, the second pipe 2 and the connecting pipe 3 is provided by the following technical solution: the first pipe 1 and the second pipe 2 are respectively threaded with the connecting pipe 3 so that the user can install the first pipe 1 and the second pipe 2 to the connecting pipe 3 respectively.

[0040] When installing this device, the user can install the first pipe 1 and the second pipe 2 at both ends of the connecting pipe 3. The threaded design makes it easy for the user to install the three together to achieve initial positioning.

[0041] After the device achieves initial positioning, the fin plate 6 can be used to lock it onto the side of the protrusion 4. The movable rod 7 allows the fin plate 6 to provide a greater pulling force to the protrusion 4 as the hydraulic pressure in the connecting pipe 3 increases. This avoids the situation in traditional structures where the hydraulic pressure can easily push open the pipe connection and cause loosening when the hydraulic pressure rises. Furthermore, this device does not require additional external force during use, which simplifies the complexity of the device to a certain extent and reduces the cost of the device.
