[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 7, being the first embodiment of this utility model, provides a sampling device for rapeseed oil quality testing, comprising: a circular mounting base 1 and a temporary sealing sleeve 2. A pair of temporary sealing sleeves 2 are provided through the circular surface of the circular mounting base 1. A cylindrical guide block 3 is provided in the inner ring of the circular mounting base 1, and a pair of symmetrical arc-shaped moving grooves 4 are provided in the arc surface of the cylindrical guide block 3. A cylindrical mounting sleeve 5 is fixedly provided in the inner ring of the pair of arc-shaped moving grooves 4. An arc-shaped moving sleeve 6 is slidably connected in the inner ring of the pair of cylindrical mounting sleeves 5. An oil inlet is provided through the circular surface of the arc-shaped moving sleeve 6 away from the cylindrical guide block 3, and an arc-shaped notch is provided in the arc surface of each cylindrical mounting sleeve 5. A rectangular drain pipe 7 is provided in the arc surface of the arc-shaped moving sleeve 6, and a limiting plate is provided inside the arc-shaped moving groove 4. A limiting groove is also provided between the limiting plates, and the rectangular drain pipe 7 and the cylindrical mounting sleeve 5 are in a rotational relationship.

[0027] A temporary fixing ring 8 is connected through the vertical surface of the rectangular drainage pipe 7. The inner ring of the temporary fixing ring 8 is rotatably connected to the oil supply hose 9. An L-shaped mounting plate 10 is installed on the circular surface of the cylindrical guide block 3. A pair of rectangular placement frames 11 are provided through the upper surface of the L-shaped mounting plate 10. A rapeseed oil storage container 12 is provided inside the pair of rectangular placement frames 11. A rectangular pressing plate 13 is hinged to the cross section of the pair of rectangular placement frames 11. An air extraction device 14 is also provided on the vertical surface of the L-shaped mounting plate 10.

[0028] The oil supply hose 9 has a threaded groove on its outer arc surface, and the temporary fixing ring 8 has a thread on its inner ring. The thread is engaged with the threaded groove on the oil supply hose 9. A pair of round holes are opened through the upper surface of the rapeseed oil storage container 12. The arc surface inside the round holes is also threaded, and this thread is engaged with the thread at the other end of the oil supply hose 9. The air extraction device 14 is equipped with a connecting pipe, and an air extraction hose is installed on the connecting pipe. The air extraction hose is also fixed to another round hole on the rapeseed oil storage container 12. A sealing ring is provided on the rod of the arc-shaped moving sleeve 6.

[0029] The arc-shaped protective sleeve 15 is fixedly connected to the arc surface of the temporary sealing sleeve 2. A circular baffle 16 is also provided on one side of the arc-shaped protective sleeve 15. A sealing block is also provided on the circular baffle 16 near the circular surface of the arc-shaped protective sleeve 15. A pair of cylindrical extension rods 17 are also provided on the circular surface of the circular baffle 16, and the cylindrical extension rods 17 penetrate through the arc-shaped protective sleeve 15.

[0030] Before use, the circular mounting base 1 is connected to the oil pipe for holding rapeseed oil. When using, first install the oil supply hose 9 on the inner ring of the temporary fixing ring 8. After confirming that the installation is in place, install the other end of the oil supply hose 9 into the circular hole that is opened through the upper surface of the rapeseed oil storage container 12. Then, connect the suction hoses provided on the rapeseed oil storage container 12 to the connecting pipes provided on the suction device 14 for temporary fixation.

[0031] After confirmation, hold the rectangular drain tube 7 by hand. The inner ring of the pair of cylindrical mounting sleeves 5 is slidably connected to the arc-shaped moving sleeve 6, and the rectangular drain tube 7 and the cylindrical mounting sleeves 5 are in a rotational relationship. The arc-shaped moving groove 4 is also provided with a limit plate inside, and there is also a limit groove between the limit plates. After pushing to the end, rotate the rectangular drain tube 7. When pushing the arc-shaped moving sleeve 6, the oil inlet provided on the arc-shaped moving sleeve 6 will contact the sealing block provided on the circular baffle 16.

[0032] At this time, the arc-shaped moving sleeve 6 will continue to move. When the oil outlet applies a pushing force to the circular baffle 16, the pushing force is greater than the pushing force provided by the memory spring. Therefore, the circular baffle 16 will move, so that the rapeseed oil inside the oil pipe comes into contact with the oil inlet. Because rapeseed oil is a viscous liquid, it will not flow into the interior of the arc-shaped moving sleeve 6 immediately. At this time, the suction device 14 can be started directly. The start of the suction device 14 can transport the rapeseed oil from the arc-shaped moving sleeve 6 into the interior of the rapeseed oil storage container 12.

[0033] Example 2

[0034] Reference Figure 3 , 56. This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a pair of rectangular plates 19 are fixedly installed on the vertical surface of the rectangular loading plate 18, and a pair of mounting blocks 20 are installed on the lower surface of one of the rectangular plates 19. The oil supply hose 9 is a disposable consumable; after sampling, it needs to be replaced with the next one. Furthermore, a section of the hose 9 is equipped with an aluminum alloy outer tube, commonly made of 6061 aluminum alloy. Its hardness is moderate, and when using a suitable tool, the annular tube can be cut off manually by pressing. Due to its good toughness, it is not prone to significant deformation after cutting.

[0035] A pair of mounting blocks 20 are provided with a U-shaped plate on their lower surface. A pair of L-shaped lifting plates 21 are also provided on the vertical surface of the rectangular loading plate 18. A cutting tool 22 is provided on the inner ring of one of the L-shaped lifting plates 21. A pair of rectangular lifting grooves 23 are provided on the vertical surface of the rectangular loading plate 18. A cylindrical guide rod 24 is also provided inside the rectangular lifting groove 23.

[0036] In use, first follow the operating steps in Example 1. After extraction is completed, first push the L-shaped lifting plate 21 away from the rectangular drainage tube 7. Press the aluminum alloy outer tube directly through the L-shaped lifting plate 21. Because the common 6061 aluminum alloy has moderate hardness, the aluminum alloy outer tube will deform under manual pressing and become flat. Then push another L-shaped lifting plate 21 so that the cutting blade 22 set in the inner ring of the L-shaped lifting plate 21 and the cutting blade 22 set in the lower surface of the rectangular plate 19 are connected to each other. Thus, the annular cylinder can be cut off by manual pressing.

[0037] Next, the suction hose connected to the rapeseed oil storage container 12 is disassembled. The disassembled suction hose is fixedly connected to the rapeseed oil storage container 12. Then, the sealing rod that matches the suction hose is installed. Finally, the originally disconnected oil supply hose 9 is replaced.

[0038] The remaining structure is the same as that in Example 1.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
