Detailed Implementation

[0006] Reference Figures 1-4 The aforementioned motor oil quality testing and sampling device is characterized by comprising an extraction body 1 and an extraction device 2 slidably inserted at the center of the lower surface of the extraction body 1. A storage device 3 is inserted at the periphery of the lower surface of the extraction body 1. Fixed support plates 4 are symmetrically connected to the upper and lower edges of the side surface of the storage device 3. An anti-slip rubber pad 5 is connected to the middle of the outer surface of each fixed support plate 4. A scale mark 6 is provided at the lower part of the side surface of the storage device 3. A collection hose 7 is inserted at the center of the lower surface of the storage device 3.

[0007] In use, first tighten the storage device 3 onto the lower surface of the extraction body 1. Then, hold the extraction body 1 with one hand and push the extraction device 2 downward with your thumb to slide it to the bottom. Next, insert the collection hose 7 under the storage device 3. Then, insert the collection hose 7 into the motor oil tank to immerse it in motor oil. Then, push the extraction device 2 upward with your thumb to make it slide upward within the extraction body 1, while simultaneously drawing motor oil into the storage device 3 through the collection hose 7. At the same time, observe whether the extraction volume is sufficient through the scale mark 6. Then, push the extraction device 2 to the top of the extraction body 1 and lock it in place. Then, unscrew the storage device 3 from the extraction body 1. Then, tighten the sealing cap onto the storage device 3. Then, pull the collection hose 7 out of the storage device 3. Finally, place the storage device 3 on the workbench and support it with the fixed support plate 4. At the same time, the anti-slip rubber pad 5 increases the friction between the fixed support plate 4 and the workbench to prevent movement.

[0008] Furthermore, the extraction body 1 includes a shell 1-1, a threaded groove 1-2, a sliding hole 1-3, and a locking hole 1-4. The threaded groove 1-2 is provided at the lower edge of the inner side surface of the shell 1-1, the sliding hole 1-3 is provided at the middle of the front of the outer side surface of the shell 1-1, and the locking hole 1-4 is provided at the center of the upper surface of the shell 1-1. The interior of the shell 1-1 is interconnected with the interior of the threaded groove 1-2, the sliding hole 1-3, and the locking hole 1-4. The shell 1-1 is made of plastic material.

[0009] When in use, tighten the storage device 3 into the threaded groove 1-1, and push the extraction device 2 to slide within the outer shell 1-1 and the sliding hole 1-3. After extraction, the extraction device 2 will be locked into the locking hole 1-4.

[0010] Furthermore, the extraction device 2 includes a rubber stopper 2-1, a sliding column 2-2, a horizontal plate 2-3, and a locking plate 2-4. The sliding column 2-2 is connected to the center of the upper surface of the rubber stopper 2-1, the horizontal plate 2-3 is connected to the center of the upper surface of the sliding column 2-2, and the locking plate 2-4 is connected to the middle of the inner side of the upper surface of the horizontal plate 2-3. The rubber stopper 2-1 and the sliding column 2-2 are inserted into the outer shell 1-1. The horizontal plate 2-3 is slidably inserted into the sliding hole 1-3. The locking plate 2-4 is L-shaped and is inserted through the locking hole 1-4. The locking plate 2-4 is locked at the outer edge of the upper surface of the locking hole 1-4.

[0011] In use, the operator pushes the card plate 2-4 backward to align it with the card hole 1-4, then presses the card plate 2-4 downward while the sliding column 2-2 slides inside the outer casing 1-1, and the horizontal plate 2-3 slides inside the sliding hole 1-3. At the same time, the rubber plug 2-1 is inserted into the storage device 3. When extracting motor oil, the operator holds the outer casing 1-1 and pushes the horizontal plate 2-3 upward with their thumb, while the sliding column 2-2 drives the rubber plug 2-1 to move upward inside the storage device 3, thus extracting motor oil into the storage device 3. Then, the card plate 2-4 is inserted through and into the card hole 1-4. Because the card plate 2-4 is L-shaped and its upper surface is etched into a trapezoidal shape, it gets stuck at the outer edge of the upper surface of the card hole 1-4 after penetrating it. Finally, the storage device 3 is unscrewed.

[0012] Furthermore, the storage device 3 includes a bottle body 3-1, a threaded ring 3-2, a connecting pipe 3-3, and a valve 3-4. The threaded ring 3-2 is connected to the perimeter of the upper surface of the bottle body 3-1, the connecting pipe 3-3 is connected to the center of the lower surface of the bottle body 3-1, and the valve 3-4 is connected to the upper side surface of the connecting pipe 3-3. The collection hose 7 is inserted below the connecting pipe 3-3, the threaded ring 3-2 is tightened in the threaded groove 1-2, and the rubber stopper 2-1 is slidably inserted into the bottle body 3-1. The bottle body 3-1 is made of transparent glass.

[0013] In use, first tighten the threaded ring 3-2 into the threaded groove 1-2, then slide the rubber stopper 2-1 to the bottom of the bottle body 3-1, then insert the collection hose 7 into the connecting pipe 3-3, then insert the collection hose 7 into the motor oil, then slide the rubber stopper 2-1 upwards while the nozzle 3-1 is under negative pressure to draw the motor oil into the bottle body 3-1 through the collection hose 7. After the oil is drawn out, the operator presses the valve 3-4 to close the valve, then unscrew the bottle body 3-1 from the threaded groove 1-2, and finally tighten the sealing cap onto the threaded ring 3-2 for storage.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
