[0031] A handheld road marking paint testing and sampling device includes a handheld part 1, a sampling cylinder 2, an opening and closing cover 3, and a cover opening assembly 4.

[0032] The hand-held part 1 includes a horizontal arm 11 for gripping and a vertical arm 12 disposed at the lower edge of the stop end of the horizontal arm 11; further, a recessed part 13 is cut and formed on the left side of the horizontal arm 11, and further still, an anti-slip wristband is provided at the stop end of the horizontal arm 11.

[0033] The sampling tube 2 is located on the lower left side of the handheld part 1. The sampling tube 2 includes a tube body 21 with an upper opening and an opening and closing protrusion ring 22 formed inside the upper edge of the tube body 21. Furthermore, the sampling tube 2 also includes a constricted tube 23 provided on the lower end face of the tube body 21, and a sealing plug is provided on the constricted tube 23.

[0034] The opening and closing cover 3 includes an opening and closing chamber 31, a rotating cover plate 32, and an adjusting ring 33;

[0035] The opening and closing chamber 31 includes an annular inner cavity 311 formed in the opening and closing protrusion ring 22, a lower opening 312 evenly distributed along the lower edge of the annular inner cavity 311, and a fixed round shaft 313 evenly distributed along the lower end face of the annular inner cavity 311 and corresponding to the lower opening 312.

[0036] The rotating cover plate 32 is evenly distributed circumferentially within the annular inner cavity 311. The rotating cover plate 32 corresponds one-to-one with the fixed circular shaft 313. The distal end of the rotating cover plate 32 is also provided with a through groove 321 arranged along its length.

[0037] The adjustment circle 33 includes a rotatable annular body 331 located in the upper half of the annular inner cavity 311, a drive plug 332 evenly distributed on the lower end face of the annular body 331 and inserted into the through slot 321, and a driven gear 333 formed on the outer edge of the annular body 331.

[0038] The opening assembly 4 is disposed inside the handheld part 1 and is used to drive the driven gear 333 to rotate. The opening assembly 4 includes an upper circular hole 41 disposed above the longitudinal arm 12, a lower coarse hole 42 disposed below the upper circular hole 41, a communicating chamber 43 disposed below the lower coarse hole 42 and communicating with the annular inner cavity 311, a sliding upper shaft 44 slidably disposed in the upper circular hole 41, a driving protrusion 45 disposed in the lower half of the sliding upper shaft 44, a driven circular tube 46 rotatably disposed in the lower coarse hole 41, a driven oblique hole 47 disposed on the inner wall of the driven circular tube 46 and cooperating with the driving protrusion 45, an annular gear 48 disposed below the driven circular tube 46 and meshing with the driven gear 333, and a compression spring 49 disposed inside the driven circular tube 46 and located below the sliding upper shaft 44.

[0039] The sampling device described in this case allows for easy hand gripping of the horizontal arm 11, followed by complete immersion of the sampling cylinder 2 into the paint carrier, ensuring that the upper end of the cylinder body 21 of the sampling cylinder 2 is below the paint liquid surface.

[0040] The opening and closing cover 3 described in this case can be easily controlled:

[0041] The sliding upper shaft 44 and the driving protrusion 45 are pressed down by the damping of the compression spring 49. The driving protrusion 45 acts on the driven oblique hole 47, thereby driving the driven round tube 46 and the ring gear 48 to rotate.

[0042] The ring gear 48 drives the driven gear 333 and the drive plug 332 to rotate.

[0043] The drive plug 332 acts on the through slot 321 to drive the rotating cover plate 32 to rotate around the fixed circular shaft 313;

[0044] The opening process occurs when the rotating cover 32 rotates away from the center of the cylinder body 21, and the closing process occurs when it rotates away from the center. The opening and closing cover 3 is opened during sampling to facilitate sampling, and the opening and closing cover 3 is closed after sampling to prevent paint from overflowing.

[0045] It should be noted that it also includes resistance adjuster 5:

[0047] Furthermore, the resistance when pressing down on the upper sliding shaft 44 can be adjusted:

[0048] Rotate the internal threaded ring 54 and the limiting protrusion ring 55, and the internal threaded ring 54 drives the limiting through hole 57 to move up and down.

[0049] The limiting through hole 57 adjusts the compression amount and elastic force of the compression spring 49 under normal conditions, and adjusts the resistance of pressing the sliding upper shaft 44.
