[0002] At present, the water filling operation of the carriages after the passenger train enters the station must be completed manually. The main steps include: before filling water, the water filling worker connects the rubber water pipe of the ground water well to the conical water injection nozzle on the car body, and then opens the water supply valve to fill water; after filling water, the water filling worker closes the water supply valve and then manually pulls out the water pipe. The defects of this water filling method are: first, it is difficult to achieve a tight connection. The conical water injection nozzles of passenger trains are of various types, while the size of the ground water pipe orifice is relatively fixed, so it is troublesome to match and difficult to achieve a good connection; second, due to the troublesome connection and the urgent time for filling water, the water filling worker has a heavy psychological burden and the labor intensity of taking over is high; third, the opening and closing of the water filling and the speed of the water filling are difficult to control, which may cause leakage and waste a lot of water.

[0039] Furthermore, the joint body includes a rubber sleeve 1, a compression sleeve 2, a first connector 3 and a second connector 4; the rubber sleeve 1 is made of elastic material, the compression sleeve 2 is sleeved on the outside of the rubber sleeve 1, and is used to compress the rubber sleeve 1, and the upper part of the rubber sleeve 1 (it can be understood that the upper and lower directions in this article refer to Figure 1 The inner side of the first connector 3 (in the up and down direction) is used for the train water injection nozzle 100 to access; the upper part of the first connector 3 is fixed to the inner side of the lower part of the rubber sleeve 1, the upper part of the second connector 4 is fixed to the inner side of the lower part of the first connector 3, and the lower part of the second connector 4 is used to extend into the interior of the upper water pipe 200 and be fixedly connected to the upper water pipe 200; the switch ring 5 is sleeved on the outer side of the first connector 3, the valve core 6 and the water sealing plate 7 are both arranged on the inner side of the first connector 3, and the notch 12 is opened on the side of the first connector 3.

[0040] In a specific embodiment, Figure 2 and Figure 3 As shown, three notches 12 can be evenly formed on the side of the first connector 3, and the angles of the three notches 12 are all 60°; accordingly, Figure 5-Figure 8As shown, the switch ring 5 and the valve core 6 can be provided with three evenly distributed mounting holes 16, and the number of the transmission member 11 is also 3; the transmission member 11 can be a pin, and the two ends of the transmission member 11 are respectively fixed on the mounting holes 16 corresponding to the switch ring 5 and the valve core 6, and the transmission member 11 passes through the corresponding notch 12, so that the user can manipulate the switch ring 5 to rotate within a range of 60° and drive the valve core 6 to rotate; in the illustrated embodiment, the contact surface of the valve core 6 and the water sealing plate 7 can each be provided with three evenly distributed water outlet holes 15, and as the valve core 6 rotates, the water outlet holes 15 are closed or connected, and the water outlet speed can be adjusted by adjusting the size of the connected part of the water outlet hole 15. It can be understood that the water outlet holes 15, notches 12 and mounting holes 16 can also be other numbers, and can also be arranged in other ways, as long as the valve core 6 can be controlled to rotate relative to the water sealing plate 7 by operating the switch ring 5 to change the opening and closing state of the water outlet hole 15.

[0041] Furthermore, as shown in the figure, the rubber sleeve 1 and the compression sleeve 2 are both hollow cylindrical structures; the first connector 3 and the second connector 4 are both composed of multiple sections of hollow cylindrical structures with different diameters, the diameter of the upper part of the first connector 3 is smaller than that of the lower part, and the diameter of the upper part of the second connector 4 is larger than that of the lower part.

When the second connecting body 4 is connected to the water pipe 200, the spring sleeve 9 and the clamping nut 10 are both sleeved on the outside of the water pipe 200; the user can control the up and down movement of the spring sleeve 9 by rotating the clamping nut 10 to adjust the degree of compression of the water pipe 200.

[0043] Specifically, when the user turns the clamping nut 10 upward, the spring sleeve 9 is squeezed to move upward, and the spring sleeve 9 moves upward along the conical inner end surface of the upper part of the cone sleeve 8, and the notch 13 gradually shrinks, thereby increasing the pressure between the spring sleeve 9 and the water supply pipe 200, thereby achieving the clamping of the water supply pipe 200; accordingly, the user turns the clamping nut 10 downward, and the spring sleeve 9 recovers under the action of its own elastic force, thereby loosening the connection between the spring sleeve 9 and the water supply pipe 200.

[0044] Preferably, the upper outer end surface of the first connecting body 3 and the lower outer end surface of the second connecting body 4 are both provided with an uneven tooth-like structure 14 to improve the tightness of the connection.
