[0026] See also Figure 1-Figure 8 The easily disassembled hydraulic valve comprises a hydraulic valve body 1 and a valve base. The bottom of the hydraulic valve body 1 is provided with a plug pin 11. The valve base has a mounting cavity 21 and a plug hole 22 for the plug pin 11 to enter or leave the mounting cavity 21. The mounting cavity 21 is provided with a first limiting member 31 and a second limiting member 32. The first limiting member 31 and the second limiting member 32 are respectively provided with a first limiting recess 311 and a second limiting recess 321. A linkage mechanism is connected between the first limiting member 31 and the second limiting member 32. The first limiting member 31 and the second limiting member 32 are respectively provided with a first limiting recess 311 and a second limiting recess 321. The first limiting member 31 and the second limiting member 32 are connected with a linkage mechanism. The first limiting member 31 The second limiting member 32 can respectively drive the first limiting recess 311 and the second limiting recess 321 to approach each other and clamp the plug pin 11 or move away from each other and release the plug pin 11 through the linkage mechanism. The user can easily control the first limiting recess 311 and the second limiting recess 321 to cooperate in clamping or releasing the plug pin 11 through the linkage mechanism, thereby realizing rapid disassembly and assembly between the hydraulic valve body 1 and the valve base, and reducing the chance of accidental separation of the hydraulic valve body 1 and the valve base, thereby improving the stability of the connection between the two.

[0027] Furthermore, a reset spring 3 is provided between the first limit member 31 and / or the second limit member 32 and the valve base. The first limit recess 311 and the second limit recess 321 move away from each other to deform the reset spring 3. The reset of the reset spring 3 can bring the first limit recess 311 and the second limit recess 321 closer to each other. The reset spring 3 can further increase the strength of the first limit recess 311 and the second limit recess 321 to clamp the plug pin 11.

[0028] Furthermore, the linkage mechanism includes a linkage block 4 and a rotating shaft 5 arranged on the linkage block 4, the rotating shaft 5 is movably connected to the valve base, the linkage block 4 can rotate around the rotating shaft 5, and the linkage block 4 is provided with a first linkage groove 41 and a second linkage groove 42 on both sides relative to the rotating shaft 5, and the first limiting member 31 and the second limiting member 32 are respectively provided with a first linkage protrusion 312 and a second linkage protrusion 322 corresponding to the first linkage groove 41 and the second linkage groove 42.

[0029] like Figure 3 , Figure 4 , Figure 8 As shown, when the first limiting member 31 moves in the forward direction, the first linkage protrusion 312 slides along the first linkage groove 41 and pushes the linkage block 4 to rotate in the reverse direction around the rotating shaft 5, so that the second linkage protrusion 322 slides along the second linkage groove 42 and pushes the second limiting member 32 to move in the reverse direction, so that the first limiting recess 311 and the second limiting recess 321 move away from each other, the plug pin 11 is released, and the reset spring 3 is deformed.

[0030] like Figure 1 , Figure 2 , Figure 7 As shown, when the reset spring 3 is reset, the first limit member 31 and the second limit member 32 respectively drive the first limit recess 311 and the second limit recess 321 to approach each other and clamp the plug pin 11, and the first linkage protrusion 312 and the second linkage protrusion 322 respectively slide along the first linkage groove 41 and the second linkage groove 42 and push the linkage block 4 to rotate in the positive direction around the rotating shaft 5.

[0031] The user only needs to drive the first limiter 31 or the second limiter 32 separately to achieve the linkage effect between the two, which simplifies the user's operation and further improves the disassembly and assembly efficiency between the hydraulic valve body 1 and the valve base.

[0032] Furthermore, a first guide groove 211 and a second guide groove 212 corresponding to the first limit member 31 and the second limit member 32 are respectively provided on the inner side of the valve base, and the first guide groove 211 and the second guide groove 212 are both arranged in the horizontal direction. The first limit member 31 and the second limit member 32 are respectively slidably matched with the first guide groove 211 and the second guide groove 212, so as to improve the stability of the movement process of the first limit member 31 and the second limit member 32, and make the connection accuracy of the first limit recess 311 and the second limit recess 321 and the plug pin 11 higher.

[0033] Furthermore, the first limit member 31 is connected to a button portion 6, which at least partially extends outward from the outside of the valve base, so that the user can apply pressure to the first limit member 31 from the outside, thereby achieving rapid disassembly and assembly of the hydraulic valve body 1 and the valve base.

[0034] Furthermore, a limiting groove 111 is provided on the plug pin 11, and the limiting groove 111 is concave inwardly toward the inner side of the plug pin 11. The first limiting recess 311 and the second limiting recess 321 can clamp the plug pin 11 by abutting against the limiting recess 111, thereby further improving the connection stability between the first limiting recess 311 and the second limiting recess 321 and the plug pin 11, thereby achieving an anti-slip effect and preventing the hydraulic valve body 1 from accidentally falling off the valve base.
