Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a brake fluid recovery device used when replacing brake fluid in an automobile.

[Prior Art] Conventionally, when replacing the brake fluid of an automobile, a hose for collecting the fluid is connected to the drain plug of the wheel cylinder, and the brake fluid is collected into a container through the hose. The diameter of the drain plug is not constant, and the size differs depending on the car model, etc., so it is necessary to prepare multiple hoses that match the diameter of the drain plug and use them selectively. There was a problem that the collection work was troublesome.

[Problems to be Solved by the Invention] An object of the present invention is to provide a brake fluid recovery device that can be commonly used for drain plugs of different diameters.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the recovery device of the present invention includes a container for storing the collected brake fluid, and a liquid container for connecting the container to a vehicle drain plug. a collection tube, said container having a cap with a plurality of holes of different sizes;
The tube is configured as an elastic tube with connection cylinders having different diameters for connecting to the drain plug at both ends thereof, and these cylinders can be freely inserted into and removed from the hole in the cap. That is.

[Function] If the drain plug of the wheel cylinder in an automobile has a small diameter, remove the small diameter tube from the cap and connect it to the drain plug while the large diameter tube of the liquid recovery tube is inserted into the hole in the cap. However, if the drain plug has a large diameter, remove the large diameter tube from the cap and connect it to the drain plug while inserting the small diameter tube of the liquid collection tube into the hole in the cap. Loosen the drain plug and collect the brake fluid into a container.

In this way, brake fluid can be recovered from drain plugs of different diameters by selectively using the cylindrical portions at both ends of the recovery tube depending on the diameter of the drain plug.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. It consists of a liquid recovery tube 2 for connecting to the plug.

A cap 3 is attached to the mouth portion 1a of the container 1, and a plurality of holes 4 and 5 of different sizes are bored in the upper surface of the cap 3. On the other hand, the tube 2 is made of a transparent elastic tube. At both ends of the tube 2, connecting tube portions 7, 8 with different diameters for connecting to a drain plug are formed, and flange-like locking members 9, 10 are formed. By inserting the cylindrical portion 7 into the large-diameter hole 4 and the small-diameter cylindrical portion 8 into the small-diameter hole 5 in the cap 3, respectively, and locking the locking members 9 and 10 on the upper surface of the cap 3, A tube 2 is attached to a container 1.

Note that 11 in the figure is a hanging member attached to the container 1.

When recovering automobile brake fluid using a recovery device with the above configuration, after starting pressure injection of new fluid into the brake pipeline, check the diameter of the drain plug of the wheel cylinder, and then If the liquid plug has a small diameter, remove the small diameter cylinder part 8 from the cap 3 while inserting the large diameter cylinder part 7 of the liquid recovery tube 2 into the hole 4 of the cap 3, and connect it to the drain plug. If the drain plug has a large diameter, remove the large diameter tube 7 from the cap 3 and connect it to the drain plug while the small diameter tube 8 of the liquid collection tube 2 is inserted into the hole 5 of the cap 3. death,
Loosen the drain plug and drain the brake fluid from tube 2.
Collected into container 1 through.

In this way, brake fluid can be recovered from drain plugs of different diameters by selectively using the cylindrical parts 7 and 8 at both ends of the fluid recovery tube 2 according to the diameter of the fluid drain plug. .

[Effects of the invention] According to the invention having the above-mentioned configuration, connecting cylindrical portions with different diameters are formed at both ends of the liquid recovery tube, so a large or small cylindrical portion can be selected depending on the caliber of the drain plug. By using a single recovery device, brake fluid can be recovered from drain plugs of different diameters.
