[0030] After the movable plates 205 are unfolded, the rotating plate 203 is rotated, and the limiting plate 204 is used to limit the state of the pressing rod 201, the limiting plate 204 is in the shape of a door with a notch at one end, by rotating the rotating plate 203 into the limiting plate 204, the unfolded state of the movable plates 205 can be locked, then the urea liquid is poured into the conical cover 106, the conical cover 106 can facilitate the user to quickly add the urea liquid, the filter plate 107 can filter the urea and prevent floating objects in the surrounding from floating into the water inlet pipe 102, and the urea in the water inlet pipe 102 flows to the filling pipe 101 to complete the filling of the vehicle urea;

[0031] After filling, the rotating plate 203 is rotated so as not to be in contact with the limiting plate 204, then the spring 202 extrudes the pressing rod 201 upward, so that the plurality of connecting rods 206 gather the plurality of movable plates 205 by traction, so that they cannot press against the inner wall of the urea tank, then the filling pipe 101 can be taken out of the urea tank.

[0032] In addition, the upper surface of each movable plate 205 is fixedly connected with a rubber rod 207, a rubber sleeve 208 is fixedly sleeved on each rubber rod 207, the rubber sleeve 208 is in a shape of a horn, a disc 209 is threadedly sleeved on the filling pipe 101, a plurality of arc-shaped plates 210 are rotatably connected to the top of the disc 209, a plurality of magnets 211 are inlaid on the top of the disc 209, the arc-shaped plates 210 are made of iron, and the arc surface of the arc-shaped plate 210 is matched with the side surface of the filling pipe 101.

[0033] When the movable plates 205 are synchronously expanded in the urea tank, the rubber rod 207 and the rubber sleeve 208 are first in contact with the inner wall of the urea tank, the rubber rod 207 and the rubber sleeve 208 are flexible, so that they can be more fitted to the inner wall of the urea tank, so that they can be used for the urea tank with a part of the filling port being designed to be inclined, so as to increase the flexibility and stability of the movable plate 205, the disc 209 is used for further increasing the stability of the filling pipe 101, so as to ensure that the filling pipe 101 will not fall off from the filling port in a special environment such as a strong wind, when the filling pipe 101 is inserted into the filling port, and the disc 209 is rotated when the plurality of movable plates 205 are synchronously expanded and enlarged;

[0034] so as to reduce the distance between the disc 209 and the bottom end of the filling pipe 101, the top of the filling port is resisted by the disc 209, so that the filling pipe 101 can be stably fixed on the filling port by cooperation of the movable plate 205, when the diameter of the disc 209 is smaller than the diameter of the filling port, the arc-shaped plate 210 is rotated, so that the arc-shaped plate 210 is in contact with the top of the filling port, and the filling pipe 101 is stably fixed on the filling port by cooperation of the arc-shaped plate 210 and the movable plate 205, after use, the arc-shaped plate 210 is rotated to be fitted to the outer wall of the filling pipe 101, the arc-shaped plate 210 is stably fitted to the outer wall of the filling pipe 101 by using the magnet 211 to attract the arc-shaped plate 210, then the disc 209 is rotated, so that the distance between the disc 209 and the bottom of the filling pipe 101 is increased, and then the filling pipe 101 can be taken out of the filling port of the urea tank.
