DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 5 As shown, this embodiment proposes a hydraulic valve block that is easy to disassemble and assemble, including a lower hydraulic valve block 2 and a valve body 3. A plurality of oil circuit sealing rings are installed inside the lower hydraulic valve block 2. The lower hydraulic valve block 2 is detachably connected to the upper hydraulic valve block 1. The bottom of the lower hydraulic valve block 2 is fixedly connected to four symmetrically arranged mounting blocks 15 by screws. The mounting block 15 is slidably assembled inside the moving block 18. The top of the moving block 18 is fixedly connected to a straight rod 22 by screws. The straight rod 22 is fixedly connected to a pull block 10 by screws. The pull block 10 is slidably assembled inside the lower hydraulic valve block 2. The moving block 18 is slidably assembled inside The round rods 19 are symmetrically arranged, and the internal sliding assembly of the mounting block 15 is equipped with two symmetrically arranged fixed blocks 13. One end of the fixed block 13 is inclined, and one side of the fixed block 13 is fixedly connected to a cross block 20 by screws. The round rods 19 are fixedly nested in the inside of the cross block 20. The lower hydraulic valve block 2 is provided with two symmetrically arranged joint pipe fittings 9. Through the arrangement of the movable block 18 and the fixed block 13 and other structures, when installing, the mounting block 15 is aligned with the mounting groove 16 and inserted. The fixed block 13 is ejected into the fixed groove 12 by the first spring 14 to complete the fixation. When disassembling, just press the pull block 10, thereby achieving the effect of quick disassembly and assembly.

[0029] like Figure 3 As shown, a mounting groove 16 is provided inside the valve body 3 , and the mounting groove 16 and the mounting block 15 have the same shape and size, and two symmetrically arranged fixing grooves 12 are provided inside the mounting groove 16 .

[0030] like Figure 3 As shown, a moving groove is provided inside the mounting block 15, and a moving block 18 is slidably connected inside the moving groove. A second spring 17 is commonly connected between the bottom of the moving block 18 and the bottom wall of the moving groove.

[0031] like Figure 3 As shown, two symmetrically arranged sliding grooves 21 are provided inside the moving block 18 , and two round rods 19 are slidably connected inside the two sliding grooves 21 .

[0032] like Figure 3As shown, the interior of the mounting block 15 is provided with two symmetrically arranged square grooves, the two fixing blocks 13 are respectively slidably connected inside the two square grooves, and the exterior of the cross block 20 is sleeved with a first spring 14, which is jointly connected between one side of the fixing block 13 and the side wall of the square groove.

[0033] like Figure 3 As shown, four symmetrically arranged grooves 11 are provided inside the lower hydraulic valve block 2 , and the pull block 10 is slidably connected inside the grooves 11 .

[0034] In this embodiment, when installing, the four mounting blocks 15 on the lower hydraulic valve block 2 are aligned with the four mounting grooves 16 and inserted. The mounting block 15 drives the fixed block 13 to move and drives the fixed block 13 to shrink into the square groove through the inclined surface of the fixed block 13 until the fixed block 13 is ejected into the fixed groove 12 by the first spring 14 to complete the fixation. When disassembling, the pull block 10 is pressed, the pull block 10 drives the straight rod 22 to move, the straight rod 22 drives the moving block 18 to move, the moving block 18 drives the two round rods 19 to move, the round rod 19 drives the cross block 20 to move, and the cross block 20 drives The fixing block 13 moves toward the inside of the square groove. When the fixing block 13 moves out of the fixing groove 12, the fixing block 13 loses the limiting effect on the mounting block 15. At this time, the lower hydraulic valve block 2 can be taken out. It should be noted that the lower hydraulic valve block 2, the upper hydraulic valve block 1 and multiple oil circuit sealing rings inside the lower hydraulic valve block 2 constitute the LED power supply body. When in use, the LED lamp and the LED power supply body are connected and can be used. The device cooperates with the moving block 18 and the fixed block 13 to make the disassembly and assembly of the lower hydraulic valve block 2 quick, thereby solving the problem of slow disassembly and assembly.

[0035] Example 2

[0036] like Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the sliding assembly of the lower hydraulic valve block 2 is provided with a baffle 23, and the baffle 23 and the lower hydraulic valve block 2 are jointly rotatably installed with a threaded rod 5, and the threaded rod 5 is fixedly sleeved with a knob 4, and the baffle 23 is internally rotatably installed with a limit disk 6, and the threaded rod 5 is fixedly nested in the inside of the limit disk 6. Through the arrangement of structures such as the threaded rod 5 and the limit disk 6, the threaded rod 5 is rotated to drive the baffle 23 to move, thereby adjusting the space inside the lower hydraulic valve block 2. The large space can reduce the turbulence and vortex of the fluid inside the valve block and reduce the risk of blockage. The large space can also accommodate more sealing materials and structures to reduce the possibility of leakage.

[0037] like Figure 5As shown, an installation cavity is opened inside the lower hydraulic valve block 2, and the baffle plate 23 is slidably connected inside the installation cavity. A rotation groove 8 is opened inside the baffle plate 23 and the lower hydraulic valve block 2, and the threaded rod 5 is rotatably installed inside the rotation groove 8. A limiting groove 7 is opened inside the baffle plate 23, and the limiting plate 6 is rotatably installed inside the limiting groove 7.

[0038] In this embodiment, when facing hydraulic components of different sizes, the knob 4 is turned, and the knob 4 drives the threaded rod 5 to rotate, and the threaded rod 5 drives the limit plate 6 to rotate. At this time, the threaded rod 5 will move. At the same time, due to the action of the limit plate 6, the threaded rod 5 drives the baffle 23 to move, thereby adjusting the space inside the lower hydraulic valve block 2. The hydraulic valve block with a larger space is more compatible with hydraulic components of different brands and models, thereby improving the flexibility and customizability of the system.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
