3. The utility model discloses set up the loose joint, can make pipeline section A's end orientation arbitrary direction through the loose joint to the connection of the hose that refuels of further being convenient for.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic structural diagram of another embodiment of the present invention.

In the figure: 1-pipe section A, 2-quick-insertion male joint, 3-quick-insertion female joint, 4-pipe section B, 5-flange, 6-fixed baffle ring, 7-thrust bearing, 8-loop, 9-movable baffle ring, 10-plug, 11-ring groove and 12-liquid through hole.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

the first embodiment is as follows:

the embodiment comprises a pipe section A1 and a pipe section B4, wherein one end of the pipe section A1 is welded with a quick-plug male connector 2, the other end of the pipe section A1 is connected with one end of the pipe section B4 through a movable joint, and the other end of the pipe section B4 is welded with a flange 5 which can be matched with an oil drain port on a transformer. The utility model discloses changed the mode of refueling of transformer, and then refueled from the oil drain port of transformer, compared with the prior art, refuel efficiency and improve greatly. And simultaneously, the utility model discloses set up the loose joint, can make pipeline section A1's end orientation arbitrary direction through the loose joint to further be convenient for refuel the connection of hose.

The movable joint structurally comprises a quick-insert male joint 2 and a quick-insert female joint 3, wherein the quick-insert male joint 2 is welded on a pipe section B4, the quick-insert female joint 3 is welded on a pipe section A1, and the pipe section B4 is a 90-degree bent pipe. The utility model discloses set up at pipe section A1's end and inserted male joint 2 soon, set up on the flexible pipe of refueling on the gasoline filler pump simultaneously and insert female joint soon after, alright realize refueling the high-speed joint of flexible pipe, be favorable to more laborsaving more convenient operation. In addition, the quick connector is adopted as a movable joint, so that the two advantages are achieved: on one hand, after the pipe section A1 is taken down from the movable joint, the refueling hose can be directly connected to the quick-insertion male joint 2 on the pipe section B4, in other words, the pipe section B can work independently, and therefore the adaptability of the utility model is improved; on the other hand, the movable joint is disassembled into two ends, so that the utility model is more convenient to carry and store.
