Hand-held steel ruler cleaning device for engineering cost

Abstract

The invention discloses a hand-held steel ruler cleaning device for engineering cost, and belongs to the technical field of equipment for engineering cost. The hand-held steel ruler cleaning device for construction cost comprises a fixed box body, wherein a bearing block is arranged on the top face of the fixed box body; a first motor is arranged in a first motor box; a spindle is arranged at the end of an output shaft of the first motor; a reel is arranged at the front end of the spindle; a wiping component is arranged at the right side of the reel; the circumferential outer wall of the spindle is sleeved with a first gear; an oscillation component is arranged at the lower side of the first gear; two triangular push blocks are arranged on the lower portion of a rotating frame; and a plurality of arc-shaped scrapers are arranged on the top face of a movable block. Through the cooperation of the triangular push blocks arranged on the lower portion of the rotating frame, the arc-shaped scrapers on the top face of the movable block and a sponge roller in the middle of a U-shaped fixing frame, when a worker cleans a steel tape, the steel tape does not need to be washed with water, the situation that the steel tape is damaged due to water residues is prevented, and the service life of the steel tape is prolonged.

Description

technical field [0001] The invention relates to the technical field of engineering cost equipment, and more specifically relates to a hand-held steel ruler cleaning device for engineering cost. Background technique [0002] Hand-held steel rulers are the most commonly used measuring tools, including steel rulers and steel tapes. A steel tape measure is a tape-shaped ruler made of thin steel sheet that can be rolled into a metal round box. In the measurement work in the early stage of the project cost, the staff often need to use the steel tape to measure the site and other targets of the construction site. Due to the generally poor environment of the construction site, some lime, mud, water stains and other dirt will inevitably adhere to the surface of the steel tape, so the relevant staff often use the hand-held steel ruler cleaning device for engineering cost. The prior art publication number is CN208853347U, which provides a tape measure cleaning device for engineering ...

AI Technical Summary

Problems solved by technology

Although these two devices have more beneficial effects, there are still the following problems: these two devices mainly use water or soaked sponge to clean the surface of the tape measure, which is difficult to clean the lime, mud and other adherents on the surface of the tape measure. Effective cleaning, the cleaning effect is poor, and it is difficult to remove the water on the surface of the tape for cleaning in this way, which will cause the tape to rust and reduce the service life of the tape. In addition, although some cleaning structures are equipped with physical scraping heads to achieve Scratch and remove the hard blocks on the tape measure, but because the scratched part is relatively small in the tape measure, if the tape measure is continuously scratched, the font symbols on the tape measure will be scratched. In addition, the existing cleaning device Regardless of whether the removal is in place, it is a single-direction continuous rotation and cleaning operation, so that the scratching effect cannot be guaranteed and feedback. In addition, the tape measure is easy to jump and misplace during the scraping and cleaning process during the forward and backward transmission process. In addition, the existing tape measure body Neither is completely straight, but has a certain depression, which makes the contact between the tape measure and the scraping head not thorough enough, so it is necessary to set up a separate guiding and pressing mechanism
