The cooling stock liquid is generally loaded in a large coolant iron barrel. In order to facilitate the extraction of the coolant, a coolant extraction device is usually required to extract the stock liquid.

[0003] Existing coolant extraction devices generally consist of a piston extraction device and a pipe connected to the oil inlet.

It requires the installation of a pipe of corresponding length for extraction. The length of the pipe cannot be changed with the size of the oil barrel. When facing cooling barrels of different sizes, in order to facilitate extraction, different lengths of pipes need to be used according to the height of the barrel. Utility Model Content

[0007] As an improvement, the piston extraction device includes a porous sealing piston and a through-hole cover for sealing the through-holes inside the porous sealing piston, and the through-hole cover is connected to the porous sealing piston via a hinge.

[0008] As an improvement, the porous sealing piston and the rotating wheel are both connected to the connecting rod through a pin structure.

[0009] As an improvement, the telescopic pipe mechanism includes several connecting pipes that are connected in sequence, a closed column groove is provided on one side of the connecting pipe, a clip is provided on the opposite side of the closed column groove, an extended clip corresponding to the clip is provided above the closed column groove, a retractable clip plate for retracting the connecting pipe is provided inside the clip end of the connecting pipe, and the outer wall of the clip passes through the retractable clip plate and the side wall of the extended clip slot.

[0010] As an improvement, a one-way valve is provided on one side of the connecting pipe with the smallest size, and the one-way valve and the oil inlet are both connected to the connecting pipe through threads.

[0011] As an improvement, the extraction shell is a single-open shell, and the open end of the extraction shell is provided with a corresponding extraction cover. The extraction shell is connected to the extraction cover by a bolt structure, and the rotating rod passes through the extraction cover.
