[0001] The utility model relates to the technical field of hydraulic multi-way valves, in particular to a hydraulic multi-way valve comprising a control mechanism. Background Art

[0002] A hydraulic multi-way valve is an important hydraulic component, which is a multi-way combined valve composed of two or more reversing valves as the main body and auxiliary devices such as a safety valve, a check valve, and a make-up oil valve according to different working requirements.

[0003] When installing the hydraulic multi-way valve body on a device for use, several connecting pipes are usually installed on several hydraulic connecting pipes to convey hydraulic oil, and then the operation lever is manipulated to change the hydraulic oil path inside the hydraulic multi-way valve body, so as to achieve the required operating effect and make it convenient to use. Since the device on which the hydraulic multi-way valve body is installed usually vibrates during operation, after a long time, the connecting pipe and the hydraulic connecting pipe may become loose and fall off, resulting in leakage of the internally conveyed hydraulic oil, causing waste, and at the same time, it may also cause the hydraulic multi-way valve body to malfunction, affecting the use of the installed device. Summary of the Utility Model

[0006] The effect achieved by the above components is: by setting the limit device, when the hydraulic multi-way valve body is installed on the equipment for use, several connecting pipes are usually installed on several hydraulic connecting pipes to transport the hydraulic oil, and then the groove plate is manually held to rotate it to a certain angle in the inner wall of the screw hole U-shaped block with one end of the rotating block as the center, so that the outer surfaces of one end of the several connecting pipes are stuck in the inner wall of the groove plate. After the groove plate is rotated to a certain angle, one end will abut on one side of the blocking block, so that it moves upward, driving the round rod to slide upward in the inner wall of the round hole block, and The spring contracts, and when it abuts against the position of the clamping hole, the clamping block can be clamped into the clamping hole under the resetting action of the spring, limiting the groove plate and the installed connecting pipe, so that when the equipment vibrates during use, it is not easy to cause the connecting pipe to loosen and fall off on the hydraulic connecting pipe, thereby avoiding the leakage of the transported hydraulic oil and causing waste, and improving the stability of the hydraulic multi-way valve body and the equipment operation. When in use, the hydraulic oil path inside the hydraulic multi-way valve body can be changed by operating the operating lever to achieve the required operating effect, making it easy to use.

[0007] Preferably, the longitudinal section of the clamping block is trapezoidal in shape, and the dimension of one end of the clamping block close to the spring is larger than that of the other end.

[0008] The effect achieved by the above components is: by setting the card block in a trapezoidal shape, after the groove plate is rotated to a certain position, the card block can be directly abutted and squeezed to shrink and then inserted into the card hole, which simplifies the operation steps and facilitates the limiting of the groove plate.

[0009] Preferably, one end of the round rod is fixedly connected to a pulling block, and the longitudinal section of the pulling block is rectangular.

[0010] The effect achieved by the above components is: by arranging the pull block, the contact area of ​​one end of the round rod can be increased, which is convenient for manually holding and pulling it, and convenient for pulling the card block out of the card hole.

[0011] Preferably, both sides of the rotating block are fixedly connected with reinforcement rods, and one end of the reinforcement rod is fixedly connected to one side of the groove plate.

One end of the bolt is spirally inserted into the threaded holes and the inner wall of the U-shaped block with screw holes.

[0016] The effects achieved by the above components are as follows: By setting the device facilitating replacement, when the groove plate is damaged after long-term use and needs to be replaced, the bolts can be spirally screwed out from the threaded holes and the inner wall of the U-shaped block with screw holes, and then hold the U-shaped block with screw holes and pull out its one end from the inner wall of the groove block, so that the groove plate and the rotating block can be disassembled from the hydraulic multi-way valve body, facilitating maintenance and replacement.

[0017] Preferably, one end of the bolt is provided with a screwing groove, and the longitudinal section of the screwing groove is hexagonal.

[0018] The effects achieved by the above components are as follows: By setting the screwing groove, when it is inconvenient to manually screw the bolt, a screwing tool with a corresponding shape can be inserted into the screwing groove to screw the bolt, facilitating operation.

[0019] Preferably, on one side of the groove block, there are symmetrically fixed limiting blocks, and the two limiting blocks are obliquely fixed on both sides at the entrance of the groove block.

One end of the groove plate will abut against one side of the clamping block and push upward, driving the round rod to slide upward in the inner wall of the round hole block and causing the spring to contract. When abutting against the position of the card hole, the clamping block can be clamped into the card hole under the reset action of the spring to limit the groove plate, limit the installed connecting pipes, so that when the equipment vibrates during use, it is not easy for the connecting pipes to become loose and fall off on the hydraulic connecting pipes, improving the stability of the hydraulic multi-way valve body and the operation of the equipment.

[0029] Example 1, as Figures 1-5As shown in the figure, a hydraulic multi-way valve including a control mechanism comprises a hydraulic multi-way valve body 1. Several operating rods 4 are rotatably connected to one side of the hydraulic multi-way valve body 1. Several hydraulic connecting pipes 5 are arranged on the top of the hydraulic multi-way valve body 1. One end of the hydraulic connecting pipe 5 is detachably connected with a connecting pipe 6 on its outer surface. Limiting devices 2 are symmetrically arranged on one side of the hydraulic multi-way valve body 1. The limiting device 2 includes a U-shaped block 21 with a screw hole. A device 3 for easy replacement is arranged between one end of the U-shaped block 21 with a screw hole and one side of the hydraulic multi-way valve body 1. A rotating block 22 is rotatably connected to the inner wall of the U-shaped block 21 with a screw hole. A groove plate 23 is fixedly connected to one side of the rotating block 22. The connecting pipe 6 is inserted into the inner wall of the groove plate 23. Card holes 24 are symmetrically formed on one side of the groove plate 23. Circular hole rods 25 are symmetrically and fixedly connected to one side of the hydraulic multi-way valve body 1. A round rod 26 is slidably connected to the inner wall of the circular hole rod 25. One end of the round rod 26 is fixedly connected with a clamping block 27. One end of the clamping block 27 is inserted into the inner wall of the card hole 24. A spring 28 is sleeved and connected to the outer surface of one end of the round rod 26. Two ends of the spring 28 are respectively fixedly connected with the clamping block 27 and one side of the circular hole rod 25. When the hydraulic multi-way valve body 1 is installed on a device for use, several connecting pipes 6 are usually installed on several hydraulic connecting pipes 5 to convey hydraulic oil. Then, manually hold the groove plate 23 and rotate it around one end of the rotating block 22 in the inner wall of the U-shaped block 21 with a screw hole to a certain angle, so that the outer surfaces of one ends of several connecting pipes 6 are clamped into the inner wall of the groove plate 23. After the groove plate 23 rotates to a certain angle, one end will abut against one side of the clamping block 27, causing it to move upward, driving the round rod 26 to slide upward in the inner wall of the circular hole block, and causing the spring 28 to contract. When it abuts against the position of the card hole 24, the clamping block 27 can be clamped into the card hole 24 under the reset action of the spring 28 to limit the groove plate 23, and limit the installed connecting pipe 6, so that when the device vibrates during use, it is not easy for the connecting pipe 6 to become loose and fall off on the hydraulic connecting pipe 5, avoiding waste caused by leakage of the conveyed hydraulic oil, improving the stability of the operation of the hydraulic multi-way valve body 1 and the device. During use, the path of the hydraulic oil inside the hydraulic multi-way valve body 1 can be changed by operating the operating rod 4, so as to achieve the required operating effect, making it easy to use.

[0030] Referring to Figures 2-4 As shown in the figure, in this embodiment, the longitudinal section of the clamping block 27 is trapezoidal, and the dimension of one end of the clamping block 27 close to the spring 28 is larger than that of the other end. By setting the clamping block 27 to be trapezoidal, after the groove plate 23 is rotated to a certain position, it can directly abut against and squeeze the clamping block 27 to make it contract and then be clamped into the card hole 24, simplifying the operation steps and facilitating the limitation of the groove plate 23. A pulling block 29 is fixedly connected to one end of the round rod 26, and the longitudinal section of the pulling block 29 is rectangular. By arranging the pulling block 29, the contact area at one end of the round rod 26 can be increased, which is convenient for manually holding and pulling it, and facilitating the pulling out of the clamping block 27 from the card hole 24.

[0031] Referring to Figures 2-4 As shown, in this embodiment, reinforcing rods 210 are fixedly connected to both sides of the rotating block 22, and one end of the reinforcing rod 210 is fixedly connected to one side of the groove plate 23. By providing the reinforcing rods 210, the connection area between the rotating block 22 and the groove plate 23 can be increased, making the connection part more firm and stable and not easily broken or damaged. On the outer surfaces of both sides of one end of the rotating block 22, bearings 211 are fixedly connected, and the outer ring of the bearing 211 is fixedly connected to the inner wall of one end of the screw hole U-shaped block 21. By providing the bearings 211, the rotational wear between both sides of one end of the rotating block 22 and the screw hole U-shaped block 21 can be reduced, improving the service life of both.

[0032] Referring to Figure 5 As shown, in this embodiment, the device 3 for easy replacement includes bolts 33. On one side of the hydraulic multi-way valve body 1, groove blocks 31 are symmetrically and fixedly connected. One end of the screw hole U-shaped block 21 is inserted into the inner wall of the groove block 31. On both sides of the inner wall of the groove block 31, threaded holes 32 are provided, and one end of the bolt 33 is spirally inserted into the inner walls of the threaded hole 32 and the screw hole U-shaped block 21. When the groove plate 23 is damaged after long-term use and needs to be replaced, the bolt 33 can be spirally screwed out from the inner walls of the threaded hole 32 and the screw hole U-shaped block 21, and then the screw hole U-shaped block 21 is held and its one end is pulled out from the inner wall of the groove block 31, so that the groove plate 23 and the rotating block 22 can be detached from the hydraulic multi-way valve body 1, facilitating maintenance and replacement.

[0033] Referring to Figure 5 As shown, in this embodiment, a screwing groove 34 is provided at one end of the bolt 33, and the longitudinal section of the screwing groove 34 is hexagonal. By providing the screwing groove 34, when it is inconvenient to manually screw the bolt 33, a screwing tool with a corresponding shape can be inserted into the screwing groove 34 to screw the bolt 33, facilitating operation. On one side of the groove block 31, limiting blocks 35 are symmetrically and fixedly connected. The two limiting blocks 35 are fixedly arranged obliquely on both sides at the entrance of the groove block 31. By providing the limiting blocks 35, the area at the entrance of the groove block 31 can be increased, facilitating the one end of the screw hole U-shaped block 21 to be quickly aligned and inserted.

[0034] Working principle: When the hydraulic multi-way valve body 1 is installed on the equipment for use, several connecting pipes 6 are usually installed on several hydraulic connecting pipes 5 to convey hydraulic oil. Then, manually hold the groove plate 23 and rotate it around one end of the rotating block 22 in the inner wall of the screw hole U-shaped block 21 to a certain angle, so that the outer surfaces of one ends of several connecting pipes 6 are clamped into the inner wall of the groove plate 23. After the groove plate 23 rotates to a certain angle, one end will abut against one side of the clamping block 27, causing it to move upward, driving the round rod 26 to slide upward in the inner wall of the round hole block, and causing the spring 28 to contract. When it abuts against the position of the card hole 24, the clamping block 27 can be clamped into the card hole 24 under the reset action of the spring 28, limiting the groove plate 23 and limiting the installed connecting pipe 6. When the equipment vibrates during use, it is not easy for the connecting pipe 6 to loosen and fall off on the hydraulic connecting pipe 5, avoiding waste caused by leakage of the conveyed hydraulic oil, improving the stability of the operation of the hydraulic multi-way valve body 1 and the equipment. During use, the hydraulic oil path inside the hydraulic multi-way valve body 1 can be changed by operating the operating rod 4, so as to achieve the required operating effect and make it convenient to use.

[0035] When the groove plate 23 is damaged and needs to be replaced after long-term use, the bolt 33 can be screwed out from the inner walls of the threaded hole 32 and the screw hole U-shaped block 21, and then hold the screw hole U-shaped block 21 and pull out one end from the inner wall of the groove block 31, so that the groove plate 23 and the rotating block 22 can be removed from the hydraulic multi-way valve body 1, facilitating maintenance and replacement.
