Description

Technical Field

[0001] This utility model relates to the field of coating testing technology, specifically to a coating sampling device for environmentally friendly coating testing. Background Technology

[0002] Paint, traditionally known as varnish in China, is a coating applied to the surface of an object to be protected or decorated, forming a continuous film that adheres firmly to the object. After the paint is produced, samples of the paint in the paint buckets need to be taken for inspection to ensure the quality of the paint sold.

[0003] However, existing environmentally friendly paint sampling devices for testing paint cannot insert the brush rod into the sampling tank for cleaning after use. They can only perform simple water treatment inside the sampling tank, which can lead to incomplete cleaning. This can result in impurities being present in the next sample, leading to inaccurate test results. Furthermore, the brush rod cannot be integrated with the sampling device, which can lead to its loss.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing environmentally friendly coating testing devices. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly coating testing device for sampling coatings, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paint sampling device for testing environmentally friendly paints, comprising a first rod, a first sampling groove inside the first rod, the top of the first sampling groove being threadedly connected to the outer side of a connecting rod, a first through hole being provided on the top of one side of the first sampling groove below the connecting rod, the upper end of the connecting rod being fixedly connected to the lower end of a second rod, a second sampling groove inside the second rod, the top of the second sampling groove being threadedly connected to the lower end of a third rod, and a second through hole being provided on the top of one side of the second rod below the third rod;

[0007] A first movable ring is movably mounted on the outer side of both the first and second rods. A first sealing ring is fixed on the inner side of the first movable ring, and the inner side of the first sealing ring is tightly fitted to the outer wall of both the first and second rods. A first fixed rod is fixed on the top of the first movable ring, and a second movable ring is fixed on the top of the first fixed rod. The second movable ring is movably mounted on the outer side of both the second and third rods. A second sealing ring is fixed on the inner side of the second movable ring, and the inner side of the second sealing ring is tightly in contact with the outer side of both the third and second rods. A second fixed rod is fixed on the top of the second movable ring, and a third movable ring is fixed on the top of the second fixed rod. The inner side of the third movable ring is movably connected to the outer side of the third rod.

[0008] Preferably, the top of the third rod is provided with a storage groove, the top of the brush rod is threadedly installed in the storage groove, and the side of the brush rod is fixed with a brush inside the storage groove.

[0009] Preferably, the brushes are evenly spaced from top to bottom on one side of the brush handle.

[0010] Preferably, there are two first fixed rods symmetrically distributed about the central axis of the first movable ring.

[0011] Preferably, there are two second fixed rods symmetrically distributed about the central axis of the second movable ring.

[0012] Preferably, the first rod, the second rod, the third rod, and the brush rod have the same maximum diameter.

[0013] Preferably, the outer side of the third rod is provided with an upper scale line and a lower scale line above and below the third movable ring, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This environmentally friendly coating testing coating sampling device, because the first rod is threadedly connected to the second rod via a connecting rod, and the second rod is threadedly connected to the third rod, and the third rod is threadedly connected to the brush rod, allows the first rod, the second rod, and the brush rod to be individually disassembled. This allows the brush rod to be inserted into the first and second sampling slots, ensuring that the inside of the first and second sampling slots is clean and convenient for future use. After use, the lower end of the brush rod can be fixed inside the storage slot, preventing loss and protecting the brush bristles, thus extending the brush's lifespan.

[0015] Move the third movable ring upwards until its top aligns with the upper scale line. Simultaneously, the third movable ring moves the second fixed rod, the second movable ring, the second sealing ring, the first fixed rod, the first movable ring, and the first sealing ring upwards, causing the first sealing ring to separate from the first through hole, and the second sealing ring to separate from the second through hole. At this point, paint at different depths in the paint bucket enters the first and second sampling slots through the first and second through holes, respectively. Then, move the third movable ring downwards until its bottom aligns with the lower scale line, causing the second fixed rod, the second movable ring, the second sealing ring, the first fixed rod, the first movable ring, and the first sealing ring to move downwards simultaneously, blocking the first and second through holes. This allows for sampling of paint at different depths in the paint bucket, obtaining multiple sets of data and ensuring the accuracy of the test. Attached Figure Description
