[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-5This utility model provides a hydraulic multi-way valve outlet hydraulic lock, including a housing 1; a baffle 28 is slidably mounted in the middle of the housing 1, a through groove 3 4 is provided in the middle of the housing 1, a clamping plate 21 is slidably mounted in the middle of the through groove 3 4, a movable plate 29 is fixedly connected to the bottom of the end of the clamping plate 21, the outer wall of the movable plate 29 is slidably connected to the middle of the baffle 28, the bottom side of the other end of the clamping plate 21 contacts a cylindrical shell 2, the outer wall of the cylindrical shell 2 contacts the inner wall of the end of the housing 1, and a sliding plate is fixedly mounted inside the other end of the clamping plate 21. Plate 26, the outer wall of which is slidably connected to the middle of cylindrical shell 2, the bottom of clamping plate 21 contacts movable sleeve 8, the top of movable sleeve 8 is fixed to slider 10, slider 10 slides in the middle of clamping plate 21, the end of movable sleeve 8 contacts adjusting block 7, the middle of adjusting block 7 contacts spring 2 9, the other end of spring 2 9 contacts side wall of cylindrical shell 2, the side wall of cylindrical shell 2 is provided with limit assembly, during operation, when it is necessary to disassemble adjusting block 7, movable sleeve 8, and spring 2 9 in the middle of shell 1. When the limit component is released from the cylindrical shell 2, the cylindrical shell 2 can be pulled to move. The cylindrical shell 2 will move the clamping plate 21 via the sliding plate 26. The clamping plate 21 will move the baffle 28 via the moving plate 29. The adjusting block 7, the moving sleeve 8, and the spring 29 will also move out from the middle of the shell 1. This eliminates the need for workers to use multiple tools to remove it from the middle of the shell 1, improving disassembly efficiency. Once the baffle 28 has completely moved out from the middle of the shell 1, the clamping plate 21 can be pulled, and the clamping plate 21 will move... The sliding plate 26 and the moving plate 29 move synchronously, and the slider 10 will also detach from the middle of the clamping plate 21. At this time, the adjusting block 7, the moving sleeve 8, and the second spring 9 can be removed separately. During installation, the adjusting block 7, the moving sleeve 8, and the second spring 9 are installed in sequence between the cylindrical shell 2 and the baffle 28, and the slider 10 is made to contact the middle of the clamping plate 21. Then, the clamping plate 21 is directly inserted into the middle of the through slot 3 4, so that the whole assembly can be inserted into the middle of the shell 1. The whole process is quick and convenient, ensuring efficient disassembly and assembly.
[0027] Furthermore, such as Figures 1-2 and Figure 5As shown, the limiting component includes a positioning plate 3, which is fixed to the outer wall of the cylindrical shell 2. A positioning groove 5 is provided on the side wall of the shell 1, and a limiting groove 11 is provided in the middle of the positioning groove 5. The positioning plate 3 contacts the middle of the positioning groove 5. A limiting block 32 is elastically connected to the middle of the positioning plate 3 via a spring 33. The end of the limiting block 32 contacts the middle of the limiting groove 11, and the limiting block 32 is slidably connected to the middle of the positioning plate 3. One end of the spring 33 is fixed to the side wall of the limiting block 32, and the other end is fixed to the middle of the positioning plate 3. A push plate 31 is fixed to the side wall of the limiting block 32. A through groove 34 is provided on the side wall of the positioning plate 3, and the outer wall of the push plate 31 is slidably connected to the middle of the through groove 34. During operation, the limiting component ensures the stability of the adjusting block 7, the moving sleeve 8, and the spring 9 installed in the middle of the shell 1. Qualitatively, when it is necessary to release the limiting component from the cylindrical shell 2, the push plate 31 can be pushed. The push plate 31 will drive the limiting block 32 to move until the limiting block 32 is completely disengaged from the middle of the limiting groove 11, thus releasing the limiting of the cylindrical shell 2. When installing the adjusting block 7, the moving sleeve 8, and the second spring 9, when the cylindrical shell 2 is pushed into the middle of the shell 1, the positioning plate 3 will enter the middle of the positioning groove 5. At this time, the limiting block 32 will contact the shell 1, and the shell 1 will push it along the inclined surface of the limiting block 32 to move into the middle of the positioning plate 3. The limiting block 32 will squeeze the first spring 33 until the limiting block 32 coincides with the limiting groove 11. The first spring 33 will push the limiting block 32 to reset through its own elasticity, so that the limiting block 32 is inserted into the middle of the limiting groove 11. Compared with the traditional method of fixing with bolts, the above method has a certain improvement in the efficiency of disassembly and assembly.
[0028] Furthermore, such as Figures 3-4 As shown, a circular plate 24 is rotatably connected to the middle of the cylindrical shell 2. A through groove 25 is provided at the end of the circular plate 24. A sliding column 27 is fixedly connected to the side wall of the bottom end of the sliding plate 26. The outer wall of the sliding column 27 is slidably connected to the middle of the through groove 25. A rotating rod 22 is fixedly connected to the end of the circular plate 24. The outer wall of the rotating rod 22 is rotatably connected to the middle of the end of the cylindrical shell 2. During operation, when it is necessary to release the clamping of multiple sets of clamping plates 21 on the adjusting block 7 and the moving sleeve 8, the rod can also be rotated. The rotating rod 22 drives the circular plate 24 to rotate. At this time, the sliding column 27 slides in the middle of the through groove 25. Since the through groove 25 is inclined, when the circular plate 24 is rotated, the sliding column 27 will move along the inclination of the through groove 25, thus moving the sliding plate 26. In this way, the clamping plate 21 will also move. Multiple clamping plates 21 move synchronously, which can quickly release the positioning of multiple clamping plates 21 on the adjusting block 7 and the moving sleeve 8, improving convenience.
[0029] Furthermore, such as Figure 3 and Figure 5As shown, a torsion spring 23 is sleeved on the outer wall of the rotating rod 22. One end of the torsion spring 23 is fixed to the end of the cylindrical shell 2, and the other end of the torsion spring 23 is fixed to the side wall of the rotating rod 22. During operation, the torsion spring 23 ensures that, without rotating the rotating rod 22 or directly pulling the clamping plate 21, multiple clamping plates 21 will stably limit the adjustment block 7 and the moving sleeve 8, ensuring the stability of the combination of the adjustment block 7 and the moving sleeve 8 when they are not installed in the middle of the shell 1.
[0030] Furthermore, such as Figure 2 and Figure 5 As shown, a sealing strip 210 is fixedly connected to the outer wall of the cylindrical shell 2 on one side of the positioning plate 3. A sealing groove 6 is opened on the inner wall of the end of the shell 1. The sealing strip 210 contacts the middle of the sealing groove 6. During operation, the sealing strip 210 can improve the sealing performance of the cylindrical shell 2 when it is closed and reduce the risk of oil leakage from the shell 1.
[0031] Furthermore, such as Figures 3-4 As shown, multiple sets of clamping plates 21, sliding plates 26, sliding pillars 27, baffles 28, and moving plates 29 are provided. These multiple sets of clamping plates 21, sliding plates 26, sliding pillars 27, baffles 28, and moving plates 29 are arranged in a circular array with the center of the cylindrical shell 2 as the origin. During operation, when the adjusting block 7, moving sleeve 8, and spring 29 are not in the middle of the shell 1, the combined state still has a certain stability, reducing the risk of them falling apart.
[0032] Furthermore, such as Figure 5 As shown, the end of the limiting block 32 is set as an inclined surface. During operation, the limiting can be completed without pushing the push plate 31 when installing the adjusting block 7, the moving sleeve 8, and the spring 9, thanks to the inclined surface, which improves convenience.
[0033] Working principle: When it is necessary to disassemble the adjusting block 7, the moving sleeve 8, and the second spring 9 in the middle of the housing 1, the push plate 31 can be pushed. The push plate 31 will drive the limiting block 32 to move until the limiting block 32 is completely disengaged from the middle of the limiting groove 11, thus releasing the limitation on the cylindrical housing 2. Then, the cylindrical housing 2 is pulled to move. The cylindrical housing 2 will drive the clamping plate 21 to move through the sliding plate 26. The clamping plate 21 will drive the baffle 28 to move through the moving plate 29. The adjusting block 7, the moving sleeve 8, and the second spring 9 will also move out from the middle of the housing 1. This eliminates the need for workers to use multiple tools to disassemble them from the middle of the housing 1, improving the efficiency of disassembly. After the baffle 28 has completely moved out from the middle of the housing 1, the clamping plate 21 can be pulled. The clamping plate 21 will drive the sliding plate 26 and the moving plate 29 to move synchronously. The slider 10 will also disengage from the middle of the clamping plate 21. At this time, the adjusting block 7, the moving sleeve 8, and the second spring 9 can be disassembled individually.
[0034] During installation, the adjusting block 7, the moving sleeve 8, and the second spring 9 are installed in sequence between the cylindrical shell 2 and the baffle 28, ensuring that the slider 10 is in contact with the middle of the clamping plate 21. Then, the clamping plate 21 is directly inserted into the middle of the through groove 4, allowing the entire assembly to be inserted into the middle of the shell 1. When the cylindrical shell 2 is pushed into the middle of the shell 1, the positioning plate 3 will enter the middle of the positioning groove 5. At this time, the limiting block 32 will contact the shell 1, and the shell 1 will be pushed along the inclined surface of the limiting block 32 to move into the middle of the positioning plate 3. The limiting block 32 will squeeze the first spring 33 until the limiting block 32 coincides with the limiting groove 11. Then, the first spring 33 will push the limiting block 32 back to its original position through its elasticity, allowing the limiting block 32 to be inserted into the middle of the limiting groove 11. Compared with the traditional bolt fixing method, the above method has a certain improvement in disassembly and assembly efficiency.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
