Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Referring to Figures 1-4, a hydraulic module oil circuit control device includes an oil circuit board assembly 1. The oil circuit board assembly 1 includes multiple connecting blocks 101, wherein each connecting block 101 has a three-way pipe oil circuit structure. Every two adjacent connecting blocks 101 are fixed together by bolts. A fixing head 102 is integrally formed on one side of the connecting block 101.

A connecting cylinder 104 is integrally formed at the top end of the connecting block 101. The top of block 101 is snapped with a first sealing ring 105. Both the first sealing ring 105 and the second sealing ring 106 are O-rings, thereby sealing the multiple connecting blocks 101. The connecting sleeve 104 of one connecting block 101 is inserted into the connecting groove 103 of another connecting block 101. By inserting the connecting sleeve 104 of one connecting block 101 into the connecting groove 103 of another connecting block 101, multiple connecting blocks 101 are assembled together according to the number of oil passages, thereby forming the oil passage board assembly 1.

[0024] The top of the oil circuit board assembly 1 is fixed with a first connecting seat 2 by bolts, the top of the first connecting seat 2 is fixed with a first solenoid valve 3 by bolts, the bottom of the oil circuit board assembly 1 is fixed with a second connecting seat 7 by bolts, and the bottom of the second connecting seat 7 is fixed with a second solenoid valve 8 by bolts.

[0025] The top of the first solenoid valve 3 is bolted to a first connecting pipe 4, and the top of the first connecting pipe 4 is bolted to an oil tank inlet connector 5. A first pressure gauge 6 is connected to a flange on one side of the first connecting pipe 4 to detect the pressure of the input hydraulic oil. The bottom of the second solenoid valve 8 is bolted to a second connecting pipe 9, and the bottom of the second connecting pipe 9 is bolted to an oil tank outlet connector 10. A second pressure gauge 11 is connected to a flange on one side of the second connecting pipe 9 to detect the pressure of the output hydraulic oil. One end of the fixing head 102 is equipped with an independent oil circuit control component 12, which includes a third solenoid valve 1201. One end of the solenoid valve 1201 is threadedly connected to one end of the fixed head 102. One end of the third solenoid valve 1201 is threadedly connected to the third connecting pipe 1202. The other end of the third connecting pipe 1202 is threadedly connected to the hydraulic cylinder oil circuit connector 1203. A flange on one side of the third connecting pipe 1202 is connected to the third pressure gauge 1204. The third pressure gauge 1204, the second pressure gauge 11, and the first pressure gauge 6 are all electronic pressure gauges. The independent oil circuit control component 12 controls the flow of oil circuits independently. A connecting plate 13 is fixed to one side of the connecting block 101 by bolts. A rubber gasket 14 is adhered to one side of the connecting plate 13. The connecting plate 13 is used to fix and install the oil circuit board assembly 1.

[0026] The working principle of this embodiment is as follows: In use, the connecting cylinder 104 of one connecting block 101 is inserted into the connecting groove 103 of another connecting block 101, thereby assembling multiple connecting blocks 101 together according to the number of oil circuits, and then forming an oil circuit board assembly 1.

Then, the hydraulic cylinder oil circuit connector 1203 is connected to the hydraulic cylinder in the hydraulic module.

[0028] When hydraulic oil is input, according to the delivery requirements, the second solenoid valve 8 is closed, the corresponding third solenoid valve 1201 is opened, and the first solenoid valve 3 is opened at the same time. The hydraulic oil in the oil tank is input to the oil tank inlet connector 5 through the oil pump, and then enters the oil circuit board assembly 1 through the first connecting pipe 4 and the first solenoid valve 3. The closed second solenoid valve 8 prevents the hydraulic oil from being discharged from the bottom of the oil circuit board assembly 1. Then it is input to the independent oil circuit control assembly 12 with the third solenoid valve 1201 open, and then supplied to the hydraulic cylinder to make the hydraulic rod of the hydraulic cylinder extend. Then the third solenoid valve 1201 is closed.

[0029] When hydraulic oil is output, according to the delivery requirements, the first solenoid valve 3 is closed, the corresponding third solenoid valve 1201 is opened, and the second solenoid valve 8 is opened at the same time. Then, under the action of the oil tank outlet pump, the hydraulic oil in the hydraulic cylinder is input into the oil circuit board assembly 1 through the independent oil circuit control component 12, and then discharged back into the oil tank through the second solenoid valve 8, the second connecting pipe 9, and the oil tank outlet connector 10. Then the third solenoid valve 1201 is closed. At this time, the hydraulic rod of the hydraulic cylinder retracts.
