[0002] In vehicle assembly production, it is necessary to use a vacuum filling machine to first evacuate the vehicle's antifreeze, power steering fluid, brake fluid and other liquid pipeline systems, and then fill the liquid into the vehicle. Current filling equipment generally uses a filling gun to seal and connect the vehicle's oil pot mouth. Since the vehicle's oil pot mouth is located on the top surface of the oil pot, the channel and other mechanisms of the connected filling gun are also located in the space above the oil pot. However, the problem with this method is that when the space above the vehicle's oil pot is small or the space shape is special, it is difficult for the current filling gun to enter and connect with the oil pot mouth, which brings inconvenience to the filling of antifreeze, power steering fluid and brake fluid.

[0003] In view of the above problems, the utility model proposes a vehicle filling gun suitable for filling in a small space, which can avoid the space above the oil tank mouth for filling and can better adapt to the connection when the space above the oil tank mouth of the vehicle is small. Specifically, the technical solution of the utility model is as follows.

[0004] A vehicle filling gun suitable for filling a small space, comprising: a filling gun handle, a plate-shaped channel, a sealing connection head, a control valve and a control button. The filling gun handle is a cylindrical structure, and its tail end is closed. The plate-shaped channel is a plate-shaped tubular structure with both ends closed, and the lower surface of its tail end is connected to the upper surface of the tail end of the filling gun handle, and the inner cavities of the two are connected. The sealing connection head is connected to the lower surface of the head end of the plate-shaped channel, and the inner cavities of the two are connected. The control valve is arranged in the inner cavity of the filling gun handle to control the opening and closing of the inner cavity. The control button is arranged on the filling gun handle and connected to the control valve, and is used to open and close the control valve.

[0005] Furthermore, the plate-shaped channel is sealed and rotatably connected to the filling gun handle to adapt to a more complex filling space.

[0006] Furthermore, the control valve comprises two valves. When in use, the two valves are connected to a vacuum filling machine through pipelines so as to fill liquid after vacuuming.

[0007] Furthermore, the head end of the filling gun handle is open, and the connecting port of the control valve faces the head end of the filling gun handle to facilitate the entry of the connecting pipeline.

[0008] Furthermore, the sealing connection mouth is a hand wheel joint, which can be conveniently connected to the oil tank mouth of the vehicle.

[0009] Furthermore, the sealing connection head has a vertically arranged filling pipe, the upper end of which is fixedly connected to the lower surface of the plate-shaped channel and the inner cavities of the two are connected, and the lower end of the filling pipe extends below the sealing connection head.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the vehicle filling gun of the utility model can utilize the plate-shaped channel to connect with the vehicle oil pot mouth for liquid filling, so that the filling gun and other mechanisms do not need to fully enter the space above the oil pot mouth to achieve filling, avoiding the space above the oil pot mouth, and can better adapt to the small space above the vehicle oil pot mouth or the special shape of the space, overcoming the problem that traditional filling guns are difficult to enter and cause inconvenience in filling antifreeze, power steering fluid, and brake fluid.
