Description

Calliper fixing device

Technical Field

The utility model relates to the field of decorative material measuring equipment, in particular to a caliper fixing device.

Background

In the field of decorative materials, currently, common length measuring tools include rulers, vernier calipers, tape measures, thickness gauges and the like. Usually, longer products are measured by using a ruler and a tape measure, but the measurement precision is only 1mm or 0.1mm, and the precision is not high; the measuring accuracy of the vernier caliper and the thickness ruler is relatively high, about 0.01mm, but the length of the vernier caliper and the thickness ruler cannot be measured by more than 2m, and the thickness ruler is limited to be less than 50 cm. The resilient floor field today uses the dimensional test standard ISO 24342. According to the ISO24342 standard, the precision requirement is 0.01mm, a vernier caliper is adopted for measurement, 3 measurement points are marked in the length direction and the width direction of the floor respectively during measurement, the dimension is measured, and then the measurement results are summed up to obtain the length or the width of the floor.

In practice, it has been found that when the flooring product is very thin (thickness less than 1cm), it is very difficult to measure the dimension between the point and the point with a vernier caliper according to ISO24342, and in particular for long-dimension flooring (. gtoreq.1 m), there is no way to align the measuring points. The reason is that: the caliper is usually made of stainless steel because of the precision requirement, and the caliper with the size of more than 500mm (large specification size) is heavy. An adult needs to hold the measuring tape by hand to ensure the balance of the measuring tape, and needs to align the measuring claw with a measuring point, so that the fact that the measuring of large-size by using the measuring tape is impossible is found in actual operation. For the floor with the size of less than 300mm, a vernier caliper with the measuring range of 0-300mm is used, the measurement can be carried out according to the ISO24342 standard, but the measurement speed is slow, 1 data can be measured in 1 minute after training, and the method is a great problem for daily supervision and control of the product size.
