Description

Technical Field

[0001] This utility model relates to the technical field of adjustable coating wet film thickness measuring ruler, specifically to an adjustable coating wet film thickness measuring ruler. Background Technology

[0002] For steel structures and marine engineering equipment, anti-corrosion coating is a crucial method, and film thickness is one of the key factors affecting its anti-corrosion performance. A thicker coating generally provides stronger corrosion resistance, but excessively thick coatings can also lead to a series of quality problems. Therefore, strict requirements are placed on the film thickness during coating application. Currently, there are two main methods for measuring coating thickness: dry film thickness measurement and wet film thickness measurement. Dry film thickness measurement must be performed after the coating has dried, which is considered a post-construction measurement. Wet film thickness measurement, on the other hand, is performed during application while the coating is still wet to correct for any deviations that may have occurred during the application process. This ensures that the coating thickness is within a reasonable range, effectively reducing paint consumption and production costs, and also preventing a series of quality problems.

[0003] CN217132046U discloses a novel coating wet film thickness measuring instrument. Made of aluminum alloy, it is lightweight, compact, easy to carry, corrosion-resistant, and reusable. All measuring teeth are integrated onto a single measuring surface, allowing for a single measurement to determine the coating's wet film thickness. The small size of the measuring teeth and zero-position tooth ensures that the wet coating self-levels after measurement, causing minimal damage to its appearance.

[0004] However, since all the measuring teeth of this measuring instrument are fixed as one piece and their length cannot be changed, its applicable range is small and it cannot measure wet films of coatings that are beyond its measurement range. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable wet film thickness measuring ruler to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses an adjustable wet film thickness measuring ruler, comprising a positive ruler plate and a negative ruler plate. The positive ruler plate and the negative ruler plate are fixed together by several bolts. Zero teeth are provided at both ends of one long side of the positive ruler plate and the negative ruler plate. The negative ruler plate is provided with a row of several tooth grooves. Measuring teeth are provided in the tooth grooves. The tooth section of the measuring teeth is narrower than the rear section. The tooth section extends out of the tooth groove towards the zero tooth. The positive ruler plate presses down on the measuring teeth.

[0008] As an improvement, there are four bolts.

[0009] As an improvement, the edges of the positive and negative rulers are completely aligned.

[0010] The advantages of this invention compared to existing technologies are as follows: the positive and negative ruler plates are detachable, and the measuring teeth in the tooth groove can be replaced according to measurement needs. The length of the tooth segments in a row of measuring teeth gradually decreases. Then, the positive ruler plate is covered and tightened with bolts. The measuring teeth are replaceable and adjustable, thus this measuring ruler has a wide range of applications. Attached Figure Description
