Description

Technical Field

[0001] The utility model relates to the technical field of hydraulics, and in particular to a hydraulic oil circuit block connection structure. Background Art

[0002] The hydraulic oil block, commonly known as the hydraulic valve block or multi-way valve block, is a very critical component in the hydraulic system. It is an integrated hydraulic component that forms a complex fluid channel network by drilling and processing in a solid metal block (usually cast iron or aluminum alloy). It is used to control the flow direction, pressure and flow of the hydraulic oil, thereby achieving precise control of the hydraulic system. Its advantage is that it simplifies the installation, inspection, replacement and subsequent maintenance of the hydraulic system.

[0003] When installing the oil pipe and the hydraulic oil circuit block, it is necessary to prepare the corresponding oil pipe joint according to the interface type reserved on the oil circuit block, such as threaded connection, ferrule joint, quick-change joint, etc., and the oil pipe is installed with the oil circuit block through the joint to complete the connection between the two. However, since the expansion of the oil pipe will be slightly larger than the joint of the hydraulic oil circuit block, the connection is not stable enough, which affects the sealing effect to a certain extent, and easily causes the risk of hydraulic oil leakage.

[0004] Therefore, in view of the above problems, a hydraulic oil circuit block connection structure with good fixing effect is proposed. Utility Model Content

[0012] Beneficial effects: 1.

Each end surface of the oil circuit block 1 is provided with a hole. A connecting pipe 2 is threadedly provided on the hole of the oil circuit block 1. The connecting pipe 2 is used for connecting the oil pipe 11 to assist its installation and operation. A mounting plate 3 is provided at the lower side of the outside of the connecting pipe 2. The mounting plate 3 is octagonal and is a carrier for mounting various components. Fixed plates 4 are provided on the front and rear sides of the top of the mounting plate 3. The fixed plate 4 is vertically arranged to facilitate the operation of subsequent components. Sliding frames 5 are slidably arranged on the two fixed plates 4. The two sliding frames 5 are arranged in opposite directions to form opposite operating trajectories for the two. An arc plate 6 is provided on the inward end surface of the sliding frame 5. The inner end surface of the arc plate 6 is an inwardly concave arc shape. The two arcs The arc plates 6 are fitted to form an annular space for the installation of the oil pipe 1. Guide rods 7 are provided on both sides of the top of the mounting plate 3. The guide rods 7 are vertically arranged. A sliding ring 8 is slidably arranged on the guide rods 7. The sliding ring 8 is an up and down sliding operation. An elastic member 81 is provided between the sliding ring 8 and the mounting plate 3. The elastic member 81 is a spring, which can assist the sliding ring 8 and its components to achieve reset operation. Pressure blocks 9 are provided on both sides of the front and back of the bottom of the sliding ring 8. Inclined blocks 10 are provided on the upper ends of the two arc plates 6. The inclined surfaces of the inclined blocks 10 extend outwardly, and the inclined blocks 10 are in contact with the adjacent pressure blocks 9. The operation of the arc plates 6 is achieved through the inclined surface cooperation. An oil pipe 11 is sleeved on the connecting pipe 2. The diameter of the oil pipe 11 is larger than the upper end diameter of the connecting pipe 2, and the oil pipe 11 is located between the two arc plates 6, which can facilitate the clamping operation of the two arc plates 6.

[0023] like Figure 3 As shown, a rubber sheet 601 is also included. The inner side of the two arc-shaped plates 6 is provided with a rubber sheet 601. The rubber sheet 601 is in a shape that fits the inner end surface of the arc-shaped plate 6, thereby forming an installation space for the oil pipe 11 to fit, and the rubber material can increase the friction of the contact surface to stabilize it.

[0024] like Figure 1 and Figure 4 As shown, it also includes a fixing ring 12, a threaded rod 13 and a nut 14. The oil pipe 11 is sleeved with the fixing ring 12, and the fixing ring 12 is located above the sliding ring 8. Threaded holes are opened around the fixing ring 12, and the sliding ring 8 is also opened around the surrounding threaded holes adapted thereto. The fixing ring 12 is penetrated and inserted with a threaded rod 13, and the lower end of the threaded rod 13 penetrates the sliding ring 8, and the threaded rod 13 fixes the position between the two by penetration. The upper end of the threaded rod 13 is threadedly provided with a nut 14, and the nut 14 is used to fix the position of the threaded rod 13.

[0025] like Figure 5 As shown, it also includes a magnetic block I15, a fixed frame 16 and a magnetic block II17. The two fixed plates 4 are fixedly provided with a magnetic block I15 on the inner side. The magnetic block I15 is embedded in the inside of the fixed plate 4, thereby saving installation space and providing an operation channel. The two arc-shaped plates 6 are provided with a fixed frame 16 on the outer side. The two fixed frames 16 are provided with a magnetic block II17. The fixed frame 16 can protect the edges of the magnetic block II17. The magnetic block II17 is magnetically matched with the adjacent magnetic block I15. The magnetic block I15 and the magnetic block II17 are in a state of opposite poles attracting each other. The operation of the components is promoted through magnetic attraction, which provides convenience for its operation.

[0026] like Figure 5 As shown, a rubber sleeve 18 is also included. The rubber sleeve 18 is arranged on the inward end of the sliding frame 5. The rubber sleeve 18 can protect the outer side of the sliding frame 5 to prevent friction contact from affecting operation.

[0027] When it is necessary to install the oil pipe 11 and the hydraulic oil circuit block 1, the staff first fixes the connecting pipe 2 on the reserved hole of the oil circuit block 1 according to the interface reserved on the oil circuit block 1, and the mounting plate 3 is fitted on the surface of the oil circuit block 1. Then, the oil pipe 11 is put on the fixing ring 12, and the staff can pass the lower end of the oil pipe 11 through the sliding ring 8 so that the lower end is sleeved on the connecting pipe 2. The fixing ring 12 slides along with the oil pipe 11 to the top of the sliding ring 8 and is placed on it. Then, the sliding ring 8 is pushed downward, so that the sliding ring 8 moves downward, and the elastic member 81 is deformed and connected with the sliding ring 8. The pressing block 9 moves downward synchronously. As the pressing block 9 moves, the pressing block 9 contacts the inclined block 10. Due to the inclined characteristic of the inclined block 10, the arc plate 6 connected to the inclined block 10 is pushed inward, and the sliding frame 5 moves synchronously on the fixed plate 4, so that the arc plates 6 on both sides are close to the surface of the oil pipe 11 and fit therewith. When the pressing block 9 moves to the end of the inclined block 10, it will abut against the outside of the inclined block 10 and abut against the two inclined blocks 10, thereby fixing the positions of the two, so that the two arc plates 6 form a clamping ring to the oil pipe 11 and the connecting pipe 2 is fixed, and at the same time, the rubber sheet 601 is in direct contact with the surface of the oil pipe 11, increasing the friction between the two, thereby achieving a more effective fixing effect. The staff can then insert the threaded rod 13 into the threaded hole between the sliding ring 8 and the fixing ring 12 to fix the position between the two, and then tighten the upper end of the threaded rod 13 through the nut 14 to prevent it from dislocating. In summary, the oil pipe 11 and the connecting pipe 2 are fixed, and the installation between the oil pipe 11 and the oil circuit block 1 is completed. If it is necessary to disassemble for inspection or cleaning, the above operation can be reversed. The screw The nut 14 is removed, the threaded rod 13 is pulled out, the sliding ring 8 is freed from the restriction, and the elastic member 81 is reset accordingly, driving the sliding ring 8 to reset upward. Under the action force, the pressing block 9 is pushed to fit the inclined surface of the inclined block 10, thereby pushing the arc plate 6 to move outward and loosening the two sides of the oil pipe 11. As the distance between the arc plate 6 and the fixed plate 4 becomes closer, the magnetic block I 15 is pushed by the magnetic force to be attracted to the magnetic block II 17, so that the arc plates 6 on both sides quickly reach the edges of the mounting plate 3, that is, the oil pipe 11 is loosened, and the staff can remove the oil pipe 11 from the connecting pipe 2.
