Description

Technical Field

[0001] The utility model relates to the technical field of level measurement, in particular to a level measuring device for construction supervision. Background Art

[0002] Construction supervision refers to a professional service activity in which a qualified engineering supervision company accepts the commission of a construction unit, undertakes its project management work, and monitors the construction activities of the contractor on behalf of the construction unit. Construction supervision ensures that all aspects of the construction project are carried out in accordance with laws and regulations, engineering construction standards, survey and design documents, and contract requirements. During the foundation construction phase, supervisors can use a level to measure at different locations on the foundation bottom surface to ensure that the flatness error of the entire bottom surface is within the allowable range. A common level is an instrument that uses laser technology for measurement. It has the advantages of high precision, high efficiency, and non-contact measurement. It is used to measure whether a plane is horizontal and vertical. By emitting horizontal and vertical laser beams, a visible laser line is formed on the target surface to determine whether the object is horizontal or vertical. It is often used in the fields of construction and decoration to help workers ensure the flatness and verticality of walls and floors. However, during transportation and use, the instrument often bumps and deforms the base, resulting in measurement errors.

[0003] The existing laser level replacement mechanism is composed of screws and nuts. The screws are usually located at the bottom and sides of the base, and some parts or labels may need to be moved to be seen. Use appropriate tools, screwdrivers and wrenches to loosen the screws, but be careful not to over-loosen and damage the screws and the base. If further cleaning and maintenance are required, the internal parts can be gently removed. Be careful not to forcibly disassemble to avoid damage. After replacing the base or completing the repair, assemble in the reverse order, put the parts back into the base, assemble the two parts and tighten the screws. However, long-term use may cause thread slippage, which may cause the base to fall off during use, resulting in measurement failure and error. Utility Model Content
