Patent Description:
In construction engineering, decoration and other industries, it is usually necessary to measure and adjust horizontal angles, and horizontal rulers are generally used as instruments for measuring the level. At present, there are many kinds of leveling rulers on the market, which can realize horizontality and verticality measurements, as well as <NUM>° angle measurements. However, the existing leveling rulers cannot realize <NUM>° all directional measurement in addition to conventional horizontality and verticality measurements. Some leveling rulers, such as electronic leveling rulers, can realize it, but they are very expensive, which is not advantageous for wide use.

In addition, when an existing leveling meter is used to measure the horizontal plane or vertical plane of an object, it must be held and fixed by hand to keep it fitted snugly to the measured object. Therefore, holding the instrument by hand determines the contact degree, and due to human factors, it will directly affect the accuracy of the measurement and limit the applicable range of the instrument. In practice, it is found that setting nano adhesive stickers on leveling instruments can make positioning convenient and the adhesive effect excellent. However, nano adhesive stickers also have the following disadvantages: for example, adsorbing dust, mud and sand; and if measurement is performing on some objects with smooth surface, such as glass and stainless steel, a nano adhesive film is easily out of position because the leveling ruler needs to frequently shift for the measurement operation. The utility model application <CIT> discloses a multifunctional positioning horizontal ruler which comprises a main ruler, a horizontal bubble tube and a vertical bubble tube, wherein the horizontal bubble tube and the vertical bubble tube are arranged on the main ruler; the horizontal bubble tube is arranged in the middle of the upper side of the main ruler; the vertical bubble tube is arranged at one end of the main ruler. The multifunctional positioning horizontal ruler is characterized in that a groove is formed in the other end of the main ruler; an angle measuring device is correspondingly inside the groove; two ends of the angle measuring device are moveably connected into the groove. Due to additional arrangement of the angle measuring device on the basis of a conventional horizontal ruler, all-directional measurement of <NUM> degrees can be realized on the basis of horizontal measurement, vertical measurement and horizontal measurement, and vertical lines connected with X, Y and Z coordinates can be measured at a time.

See <FIG>, the present application provides a multifunctional leveling meter for convenient positioning using nano adhesive stickers comprising a leveling ruler <NUM> which is a hollow section bar. The leveling ruler <NUM> is provided with a horizontal leveler <NUM> and a vertical leveler <NUM>, respectively. The horizontal leveler <NUM> is arranged within the lower end of the leveling ruler <NUM>, and the vertical leveler <NUM> is arranged on the left side of the leveling ruler <NUM>. The left side surface of the leveling ruler <NUM> is sticked and fixed with at least two nano adhesive stickers <NUM> for convenient positioning. An adhesive sticker positioning structure is arranged against the nano adhesive sticker <NUM>. The nano adhesive sticker <NUM> has the characteristics of ease of use and high fixability, and can be applied in many application scenarios, for example, it can be sticked on any smooth surface. For example, it can be sticked on glass facades, stainless steel surfaces, wood surfaces, aluminum surfaces, ceramic tiles and painted walls, etc. When in use, an operator holds the right side of the leveling ruler <NUM>, and fit the left side of the leveling ruler <NUM> snugly to the surface of the object to be measured. Applying nano adhesive sticker <NUM> on the multifunctional leveling meter is a new breakthrough in measurement applied technology. As another embodiment, several magnet blocks can be fixedly arranged inside the right side of the leveling ruler <NUM> of the present application, and the multifunctional leveling meter can be tightly sucked on the surface of the object to be measured of iron through the magnet blocks, so that the multifunctional leveling meter can be more widely utilized. In the present application, the multifunctional leveling meter can be directly sticked on the surface to be measured by the nano adhesive sticker <NUM> on the side or sucked tightly on the surface of the object to be measured made of iron by means of magnetic attraction, so as to facilitate operators to place the leveling meter, improve operation efficiency and show a better measuring effect.

In the present application, the adhesive sticker positioning structure comprises a positioning and mounting base <NUM> inserted into the leveling ruler and a positioning and mounting plate <NUM>, wherein the upper surface of the positioning and mounting plate <NUM> is provided with a cavity <NUM> for accommodating the nano adhesive sticker. Directional insertion slots <NUM> are respectively provided on the left and right sides of the positioning and mounting base <NUM>, and insertion portions <NUM> fitted with the directional insertion slots <NUM> are provided on the left and right sides of the positioning and mounting plate <NUM>.

Further, a positioning cavity <NUM> is provided in the slot wall of the directional insertion slot <NUM>, and the insertion portion <NUM> is provided with a positioning bump <NUM> corresponding to the positioning cavity <NUM>. When the positioning and mounting plate <NUM> and the positioning and mounting base <NUM> are inserted into place, the positioning bump <NUM> is exactly located in the positioning cavity <NUM>, which can avoid the error of not being mounted in place. Further, the outer side of the positioning and mounting plate <NUM> is provided with a metal pressing frame <NUM> for reinforcing the nano adhesive sticker.
