Background

The scale is an indicator composed of a group of ordered scale marks and related numbers, is a length standard of an optical measuring instrument, is widely applied to instruments for measuring length, such as a tool microscope, a length measuring instrument, a measuring machine and the like, and is used for common surveying scales aiming at the ground with small elevation difference. This disadvantage is particularly pronounced in railway mapping applications.

The utility model discloses a scale for railway survey and drawing in the prior art (publication number: CN 216074549U), relates to survey and drawing scale technical field. The back of first scale sets up a scale case that is used for loading the second scale, and first scale is close to scale case open-ended one end middle part and is equipped with the locating piece, and second scale one end is provided with locating piece matched with constant head tank on the first scale, and this one end of second scale still sets up a transversely run through's mounting hole simultaneously, and the second scale card is on first scale, and the locating piece inserts in the constant head tank this moment. When the height of the first scale does not meet the requirement, the lock catch is rotated, the cover plate is opened, the compression spring loses the constraint release elasticity to push the pressing block, and the second scale is driven to pop out of the scale box. And inserting the second scale into the positioning block, and sequentially inserting and fastening the positioning block and the mounting hole by using bolts. Therefore, the measuring height of the staff gauge can be increased, the situation that the traditional staff gauge is limited in measuring height and cannot meet the measurement in the high-range difference area is avoided, and the combined staff gauge is effectively prevented from being used and the usability of equipment is improved.

However, when the device is used, the second scale is popped up from the scale box through the compression spring, and as the elasticity of the spring can be reduced along with the increase of the using times, after long-time use, the length of the second scale popped up by the compression spring is reduced, so that the length measurement error is increased during use, and the measurement result is influenced.
