Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and more specifically, to a land area measuring device. Background Technology

[0002] Land area, also known as parcel area, refers to the land area within the boundary line of a parcel's ownership. The principle of area measurement is to use the map sheet as the basic control, measure the area by sheet, adjust the area ratio, and summarize from bottom to top. With the development of science, economy and technology, land area measurement is a very common and necessary task. When measuring and processing land area, a land area measurement device is required.

[0003] In existing measuring devices, the winding of the graduated tape is generally done manually or by motor. While both methods can effectively wind the tape, manual winding reduces efficiency and increases the workload for operators. Motor winding increases the overall purchase and maintenance costs of the measuring device. Furthermore, existing measuring devices cannot easily and effectively adjust the horizontal angle, requiring manual re-fixing when measuring different orientations, further reducing measurement efficiency. Moreover, existing measuring devices cannot easily disassemble, replace, or clean the cleaning components, reducing overall practicality.

[0004] Comparing this application to Chinese Patent Publication No. CN219714271U, this application belongs to the field of measuring device technology, and particularly relates to a land area measuring device, including a measuring instrument. A vertically set winding shaft is rotatably mounted on the inner wall of the measuring instrument. A take-up roller is fixedly sleeved on the outer wall of the winding shaft. A graduated measuring tape is horizontally wound on the outer surface of the take-up roller. An inlet / outlet is provided on the side of the measuring instrument. One end of the graduated measuring tape passes through the inlet / outlet and is fixedly connected to a collar. A directional stake is fixedly connected inside the collar. In this invention, the measuring instrument is placed at the designated measurement position, and a servo motor drives the winding shaft to slowly reciprocate, allowing the take-up roller to wind and release the graduated measuring tape. During measurement, the graduated measuring tape can be pulled to the designated position using the directional stake, which is then fixed at this measurement position. The scale value on the measuring tape can then be obtained. After use, the measuring tape is simply rewound back into the measuring instrument, making it very convenient to use.

[0005] The above scheme can conveniently measure the land area by using a scale tape, but the scheme still uses a motor to wind the scale tape, and the scheme cannot conveniently and effectively adjust the horizontal angle of the device as a whole, and the scheme still cannot effectively disassemble, replace and clean the cleaning assembly, and cannot solve the problems in the background art.

[0006] Therefore, the skilled in the art provides a land area measuring device to solve the problems in the background art. Utility model content
