Description

Technical Field

[0001] The utility model belongs to the technical field of washing liquid filling, and particularly relates to a telescopic washing liquid filling pipe. Background Art

[0002] At present, most of the washing liquid tanks for automobiles are arranged in the front engine compartment. The lower part of the washing liquid filling pipe is connected to the washing liquid tank, and the pipe orifice part is fixed to the vehicle body. To ensure that the engine hood will not press against the pipe orifice of the washing liquid filling pipe when it is closed, the height of the pipe orifice of the washing liquid filling pipe is usually flush with the surrounding parts or lower than the surrounding parts.

[0003] Most of the washing liquid bottles on the market have a large-diameter bottle body and a small-diameter bottle mouth. When filling the washing liquid, there is a height difference between the bottle mouth and the pipe orifice of the washing liquid filling pipe. It is very easy to cause that when filling starts, the washing liquid cannot accurately enter the pipe orifice of the washing liquid filling pipe, and the washing liquid is likely to spill onto other parts of the engine compartment (such as the front engine compartment decorative cover plate), resulting in problems such as fouling and corrosion.

[0004] The purpose of the utility model is to provide a telescopic washing liquid filling pipe to solve the problems put forward in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A telescopic washing liquid filling pipe includes a liquid inlet pipe and a stretching pipe. The stretching pipe is inserted into the liquid inlet pipe from top to bottom. The upper end of the stretching pipe is provided with a liquid inlet hopper. A collar is slidably sleeved on the surface of the liquid inlet pipe. The tops of both sides of the collar are fixedly connected with connecting rods. The upper ends of the connecting rods penetrate above the liquid inlet pipe and are fixedly installed with the liquid inlet hopper. A first spring is sleeved on the connecting rods. Two spaced positioning grooves are opened on both sides of the liquid inlet pipe. Positioning components are provided on both sides of the collar.

[0006] As a preferred implementation manner, handles are fixedly connected to both sides of the liquid inlet hopper.

[0007] As a preferred implementation manner, a filter screen is fixedly connected inside the stretching pipe.

[0008] As a preferred implementation manner, the positioning component includes a positioning rod and a second spring. The positioning rod slidably penetrates through the collar, and the second spring is sleeved on the positioning rod.

The stretching tube 2 is inserted into the liquid inlet tube 1 from top to bottom. The upper end of the stretching tube 2 is provided with a liquid inlet hopper 3. Both sides of the liquid inlet hopper 3 are fixedly connected with handles 9. Through the arrangement of the stretching tube 2 and the liquid inlet hopper 3, when adding washing liquid, the handle 9 can be used to pull the liquid inlet hopper 3 upward, so that the liquid inlet hopper 3 drives the stretching tube 2 to extend upward along the liquid inlet tube 1, which can make the liquid inlet hopper 3 fully close to the bottle mouth, and add washing liquid into the liquid inlet tube 1 through the liquid inlet hopper 3, which can avoid the splashing of the washing liquid.

[0022] Referring to Figure 2 and Figure 3 , a collar 4 is slidably sleeved on the surface of the liquid inlet tube 1.
