Description

Technical Field

[0001] The utility model relates to the field of level ruler calibration, in particular to a calibration platform for a tower ruler. Background Art

[0002] The tower ruler is a type of level ruler. Most of the early level rulers were made of wood, which was heavy and limited in length (usually 2m), making it inconvenient to carry when measuring. Later, it was gradually made of lightweight and high-strength materials such as aluminum alloy. It adopts a tower-shaped retractable form, which is easy to pull out when in use. The single elevation measurement range is greatly improved. The length is generally 5m. It can be retracted when carried. Because its shape is similar to a tower, it is often called a tower ruler.

[0003] Most of the tape measure is a rectangular pull-out structure. Each time a section is pulled out, a spring pops out. When using it, be sure to pay attention to whether the spring is in place, otherwise it will cause measurement errors. In order to facilitate observation and debate, a red dot is marked above or below the tape measure number. If there is a red dot on the number, it means a 1m range, two red dots mean a 2m range... and so on. If the number on the tape measure is "4", it means 4m.

[0004] When the temperature and humidity of the air change, the length of the scale must remain stable or change only slightly. The scale of a general precision level is painted on an Invar strip, which is stretched in the groove of the wooden ruler with a certain tension, so that the length of the Invar strip will not be affected by the expansion and contraction of the wooden ruler. The scale scale numbers are marked on the wooden ruler on both sides of the Invar strip.

[0005] The scale of the tower ruler must be very accurate and precise, and the accidental error and systematic error of the scale should be very small. The magnitude of the accidental error and systematic error of the scale of the tower ruler is mainly determined by the level of the scale graduation process. The accidental mean error of the current precision tower ruler scale is generally 8 to 11 m. Since the systematic error of the precision tower ruler scale can be corrected by the average true length per meter of the tower ruler, the accidental error of the scale represents the comprehensive accuracy of the scale.

[0006] The structure of the tower ruler should ensure that the entire length is straight, and the ruler body is not prone to deformation such as length and bending. The wooden ruler body of a general precision tower ruler should be made of high-quality wood that has been specially treated. In order to prevent the bottom of the tower ruler from wearing out during use and changing the length of the ruler body, a strong and wear-resistant metal base plate must be nailed to the bottom of the tower ruler.

[0007] The existing tower ruler calibration device has not been reported yet. Utility Model Content
