Embodiment 1
[0042] see Figure 1-5 , the oil testing and sampling device of the present invention includes a sleeve 1 and a sampling inner cylinder 3, a group of arc-shaped plates 13 with scale marks 14 engraved on the outer surface of the sleeve 1 are provided on both sides of the top surface of the sleeve 1, and the sampling inner cylinder 3 is located at The inner side and the outer side of the sleeve 1 are provided with a threaded path, the outer side of the sampling inner cylinder 3 is threadedly connected with the sampling outer cylinder 7, both sides of the sampling inner cylinder 3 are provided with openings 11, and the top edge of the sampling inner cylinder 3 is provided with a connection Plate 4, the center of the bottom of the inner wall of the sampling outer cylinder 7 is provided with a connecting rod 12 whose top protrudes to the top of the sleeve 1, the top of the connecting rod 12 is provided with a fixed plate 15, and the outer side of the fixed plate 15 is provided with ...
Embodiment 2
[0045] Unlike Example 1, see figure 1 The outer side of the sleeve 1 and the position near the bottom is provided with an air bag 5 along the ring, the air bag 5 and the sleeve 1 are in a sealed state and the inside is filled with air, and the positions between each group of arc-shaped plates 13 and near the top The fixed rods 23 are integrally formed, and the two fixed rods 23 are respectively located directly above the convex plate 21 .
[0046] Through the above design, when the device is placed in the petroleum liquid, the buoyancy between the air bag 5 and the petroleum can make the sleeve 1 always be on the petroleum liquid level, preventing the sleeve 1 from being inserted into the petroleum and causing Inconvenient to use, at the same time, through the structural design of the position of the fixed rod 23, the effect of restricting the connection of each set of arc-shaped plates 13 can be achieved, making the state of each set of arc-shaped plates 13 more stable, preve...
Embodiment 3
[0048] Unlike examples 1 and 2, see Figure 1-4 , the sleeve 1, the sampling inner cylinder 3 and the sampling outer cylinder 7 are all designed with a cylindrical structure, the surface of the sleeve 1 and the positions near the tops of both sides are provided with protrusions 2, and the protrusions 2 are far away from the end of the sleeve 1 Fixed ring 8 is provided, and the inner side of metal ring 17 and fixed ring 8 is provided with latex ring 18 along the ring, and the surface of metal ring 17 and fixed ring 8 is made as smooth surface and is all round and smooth shape design near the position of edge.
[0049] Through the above-mentioned design, when the inspector needs to quantitatively discharge the sample in the sampling inner cylinder 3, the inspector can use his hands and fingers to insert into the inside of two fixed rings 8, lift them up, and then use In addition, the hand of the limb is inserted into the inside of a metal ring 17 and rotated counterclockwise to ...
