[0030] Reference Figure 1-6 This utility model provides a multifunctional hydraulic conversion connector, which includes a connecting device 1, a connecting pipe 2, and a docking device 3. The connecting device 1 includes a connecting frame 10, which is fixedly connected to the connecting pipe 2. A first sealing ring 11 is fixedly connected to the front of the connecting frame 10, and a first mating joint 12 is fixedly connected to the front of the connecting frame 10. A connecting ring 13 is provided in the middle of the first mating joint 12, and a sealing ring 14 is fixedly connected to the rear of the first mating joint 12. The first sealing ring 11 corresponds to a second sealing ring 35, and the first sealing ring 11 and the second sealing ring 35 are tightly fitted together. The sealing ring 14 is in close contact with the inner wall of the second mating joint 34.

[0031] The aforementioned structure, by incorporating a docking device 3, allows the operator to install one docking device 3 onto the hydraulic pump to be connected, and another docking device 3 onto the hydraulic equipment to be connected, thus facilitating subsequent docking. The inclusion of a connecting device 1 and a connecting pipe 2 allows the operator to connect the hydraulic pump and hydraulic equipment, both equipped with docking devices 3, via the connecting pipe 2, which has the connecting device 1 fixed at both ends.

[0032] By providing a first sealing ring 11 and a second sealing ring 35 that correspond to each other, when the operator inserts the first connector 12 into the interior of the second connector 34, the front of the second sealing ring 35 is inserted into the interior of the first sealing ring 11, and the two fit tightly together. Through the tight fit of the first sealing ring 11 and the second sealing ring 35, the initial sealing of the connecting device 1 and the docking device 3 is completed.

[0033] By providing a sealing ring 14, when the operator inserts the first connector 12 into the second connector 34, the sealing ring 14 is inserted into the second connector 34 and fits tightly against the second connector 34, thus completing the secondary sealing of the connecting device 1 and the docking device 3.

[0034] With the cooperation of the first sealing ring 11 and the second sealing ring 35 with the sealing ring 14 and the second connector 34, that is, through the double sealing action, the hydraulic oil is not easy to leak from the connection between the connecting device 1 and the docking device 3 during the connection process and during the operation of the hydraulic equipment, thus ensuring the stable operation of the hydraulic equipment.

[0035] A first sliding frame 15 is fixedly connected inside the connecting frame 10. A pressing block 16 is slidably connected above the first sliding frame 15.

A first spring 19 is fixedly connected inside the telescopic frame 18. A fixed frame 110 is fixedly connected to the other end of the first spring 19. The telescopic frame 18 and the fixed frame 110 are slidably connected. The fixed frame 110 is fixedly connected to the connecting frame 10. A locking block 111 is fixedly connected to the other end of the connecting rod 17. A second sliding frame 112 is slidably connected below the locking block 111. The second sliding frame 112 is located inside the connecting frame 10 and is fixedly connected to the connecting frame 10.

[0036] The above structure includes a pressing block 16, with a connecting rod 17 fixedly connected to the lower part of the pressing block 16 and a locking block 111 fixedly connected to the other end of the connecting rod 17. This allows the pressing block 16, connecting rod 17, and locking block 111 to move downwards synchronously when the operator presses the pressing block 16. Specifically, the pressing block 16 enters the interior of the first sliding frame 15, and the locking block 111 enters the interior of the second sliding frame 112. A telescopic frame 18 is fixedly connected to the middle of the connecting rod 17. A first spring 19 is fixedly connected inside the telescopic frame 18, and a fixed frame 110 is fixedly connected to the other end of the first spring 19. After the pressing block 16 is pressed, the first spring 19 retracts, and the telescopic frame 18 enters the interior of the fixed frame 110.

[0037] In the above structure, when the operator inserts the connecting device 1 into the docking device 3 and releases the pressure on the pressing block 16, the pressing block 16, the connecting rod 17 and the locking block 111 move upward under the rebound action of the first spring 19. At this time, the locking block 111 is inserted into the sliding locking tube 32, thereby completing the first docking lock of the connecting device 1 and the docking device 3.

A sliding locking tube 32 is fixedly connected to the other end of the second spring 31. The sliding locking tube 32 is slidably connected to the docking tube 30 and to the connecting frame 10. The sliding locking tube 32 is inserted into the locking block 111. A limit ring 33 is fixedly connected to the middle of the docking tube 30. A second docking connector 34 is fixedly connected to the front of the docking tube 30. A second sealing ring 35 is fixedly connected to the front of the second docking connector 34. A locking frame 36 is fixedly connected to the inside of the second docking connector 34. A third spring 37 is fixedly connected to the inside of the locking frame 36. A locking ball 38 is fixedly connected to the other end of the third spring 37. The locking ball 38 is slidably connected to the locking frame 36. The locking ball 38 corresponds to the connecting ring 13 and is in close contact with the first docking connector 12.

[0039] The above structure includes a locking frame 36, with a third spring 37 fixedly connected inside the locking frame 36, and a locking ball 38 fixedly connected to the other end of the third spring 37. The locking ball 38 corresponds to the connecting ring 13, so that when the operator inserts the connecting device 1 into the docking device 3, the locking ball 38 enters the connecting ring 13, thereby completing the second docking lock of the connecting device 1 and the docking device 3.

[0040] The second pair of connectors 34 is provided, and twelve of them are fixed in an internal surrounding array.

[0041] The sliding locking tube 32 is provided, and corresponding marks are provided on both the upper and lower sides of the sliding locking tube 32, which makes it easier for operators to align the locking block 111.

[0042] Working principle: When using this multi-functional hydraulic adapter, first connect the connecting frame 10 to the front of the docking pipe 30, and insert the first docking pipe 12 into the interior of the second docking pipe 34.
