Problems solved by technology
However, most of the construction sites are muddy, and the steel tape will inevitably be stained with mud when it is used, which makes it easy to block the entrance and exit of the tape when the tape is retracted, making it difficult to collect the tape, and the soil on the tape is not easy to clean. It is easy to cause the tape to be stretched and the tape to rust, which will affect the measurement accuracy and service life of the steel tape

The invention belongs to the technical field of measurement, and discloses a mud-proof measuring ruler which comprises a ruler frame, a cleaning assembly and a ruler belt. A rotating shaft capable ofrotating relative to the ruler frame is arranged on the ruler frame, the cleaning assembly is arranged on the ruler frame, the cleaning assembly comprises two mud scraping pieces which are arranged atintervals, the ruler belt is wound on the rotating shaft, the tail end of the ruler belt is fixed on the rotating shaft, and the ruler belt can pass through the space between the two mud scraping pieces when being unfolded and rolled. According to the mud-proof measuring ruler, the two mud scraping pieces are arranged on the ruler frame, mud adhering to the front face and the back face of the ruler belt can be scraped off when the ruler belt is wound, the ruler belt can be flexibly wound without jamming, the ruler belt does not need to be wiped deliberately, rusting of the ruler belt is effectively avoided, the measuring precision of the anti-mud measuring ruler is maintained, and the service life is prolonged.
Description
Technical field [0001] The invention relates to the technical field of measurement, in particular to a mud-proof measuring ruler. Background technique [0002] In building construction, steel tape measure is usually used for measurement. However, the construction sites are mostly muddy. The steel tape will inevitably be stained with soil during use, which makes the tape easy to block the entrance and exit of the tape when it is retracted, which makes it difficult to remove the tape, and the dirt on the tape is not easy to clean. Sometimes it is easy to cause the tape to be stretched and the tape to rust, which affects the measurement accuracy and service life of the steel tape. Summary of the invention [0003] The purpose of the present invention is to provide a mud-proof measuring ruler, which can scrape off the soil on the tape when the tape is reeled, and effectively maintain the measurement accuracy. [0004] To achieve this goal, the present invention adopts the following te...
