Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, in particular to a multi-channel oil-electric-hydraulic quick synchronization connector. Background Art

[0002] Construction machinery and some special equipment usually use pipelines such as lubricating oil pipes, cables and hydraulic oil pipes to achieve fast, stable and accurate connection of lubricating oil, electricity and hydraulic signals between different components or modules.

[0003] Existing connectors often have a single function. In order to achieve the connection of oil, electricity and liquid, multiple independent connectors need to be used respectively. This not only increases the number, volume and weight of the connecting parts, but also fails to achieve synchronous connection of each channel during the connection process. In addition, the efficiency is low because each channel needs to be connected separately. During the docking installation, the existing connectors cannot guarantee that the plug base and the socket base can be successfully docked at one time every time, which will increase the workload of the operator's repeated operations. At the same time, it is not convenient to seal the connection between the plug base and the socket base. Summary of the invention

[0033] Working principle: When starting to work, the plug base 1 and the socket base 2 are located at the top of the elastic Z-shaped plate 7. Rotate the left threaded cylinder 11, and the left threaded cylinder 11 drives the left threaded rod 12 to rotate. The left threaded rod 12 drives the left connecting plate 13 to move. The left connecting plate 13 drives the left support plate 16 to move through the left limiting plate 14 and the left U-shaped block 15. The left support plate 16 drives the two left elastic Z-shaped plates 7 to swing through the left T-shaped plate 17. The two left elastic Z-shaped plates 7 limit the plug base 1. Then the operator pulls the elastic rope 18, and the elastic rope 18 drives the first swing plate 4 to move. The first swing plate 4 drives the socket base 2 to move through the adjacent connecting rod 21. The socket base 2 moves through the inclination angle of the right elastic Z-shaped plate 7, so that the plug base 1 and the socket base 2 are on the same horizontal plane. The socket base 2 will gradually approach the plug base 1, and the electrical plug 101 is inserted into the electrical socket 201, the guide rod 102 is inserted into the blind hole, and the lubricating oil plug 103 is inserted into the lubricating oil socket 202. The female hydraulic quick connector 104 is connected to the male hydraulic quick connector 203. Thus, the plug base 1 and the socket base 2 are connected. When connecting and disconnecting this device, there is no need to manually operate the lubricating oil pipe, cable, and hydraulic pipe; when the connector is connected and disconnected, there are no lubricating oil pipes, cables, and hydraulic pipes on the connection surface; the lubricating oil circuit, electrical circuit, and hydraulic oil circuit are connected or disconnected synchronously. When the plug base 1 is inserted into the socket base 2, the synchronous connection of the lubricating oil circuit, electrical circuit, and hydraulic oil circuit can be achieved; when the plug base 1 is pulled out from the socket base 2, the synchronous disconnection of the lubricating oil circuit, electrical circuit, and hydraulic oil circuit can be achieved. The two U-shaped sealing strips 3 are used to seal between the plug base 1 and the socket base 2. The elastic adjusting plate 22 and the fixing block 23 can limit the plug base 1 and the socket base 2. After the plug base 1 and the socket base 2 are connected, rotate the right threaded cylinder 11, and the right threaded cylinder 11 drives the right threaded rod 12 to rotate. The right threaded rod 12 drives the right connecting plate 13 to move. The right connecting plate 13 drives the right support plate 16 to move through the right limiting plate 14 and the right U-shaped block 15. The right support plate 16 drives the two right elastic Z-shaped plates 7 to swing through the right T-shaped plate 17. The two right elastic Z-shaped plates 7 limit the socket base 2.
