Description

Technical Field

[0001] This utility model relates to the field of measurement, specifically a measuring device for drawing blueprints. Background Technology

[0002] In construction and other construction processes, it is necessary to measure the dimensions of buildings and external facilities. Different measuring devices are needed to collect the measurements, facilitating subsequent drafting. A drafting and measuring device disclosed in application number CN202322923686.9 describes a device comprising a mounting plate, a support plate fixedly connected to the upper surface of the mounting plate, a transmission rack fixedly connected to the surface of the support plate, a placement groove on the surface of the support plate, a movable frame fixedly connected to the surface of the placement groove, the movable frame fitting onto the surface of the support plate, and a forward and reverse motor fixedly connected inside the movable frame, with the output shaft of the forward and reverse motor fixed... The drawing and measuring device is connected to a rotating shaft, with a transmission gear fixedly connected to the surface of the shaft. By setting up forward and reverse motors, when the operator uses the device to perform measurements, the operator only needs to start the forward and reverse motors via a control switch. This allows the transmission gear to drive the measuring instrument body inside the placement slot through the movable frame, thus facilitating the operator to adjust the drawing height of the measuring instrument body. However, the above description still has the following drawbacks in actual use: the measuring device is not convenient to place and adjust according to terrain factors, which limits the use of the device. Therefore, it is necessary to design a more practical measuring device for drawing. Utility Model Content
