Description

Digital display flexible rule head structure and measuring device

Technical Field

The utility model belongs to the technical field of flexible rule measurement, and particularly relates to a digital display flexible rule head structure and a measuring device.

Background

The common tape measure in our life is generally divided into a steel tape measure and a flexible rule, wherein the steel tape measure is generally used for straight line measurement, and the flexible rule is used for curved surface or perimeter measurement. Both of these tapes are available in the market in which the tape scale is read by the naked eye to obtain measurement data. Along with the technical progress in the market, a few digital display flexible rulers appear, the trouble of reading scale values by human eyes is avoided, the obtained measurement data are more accurate, the measurement values can be transmitted to electronic equipment terminals such as mobile phones by adopting Bluetooth, and the like, so that the storage of the measurement data, the reanalysis and the comparison of the data and other expansion applications are more greatly facilitated. However, the digital display tape already on the market also has some problems, such as: when the tape head is used for measuring the circumference length, the fixing and the dismounting operations are troublesome; the length measuring mode and the circle measuring mode of some products need to be switched in function, and many users easily omit the operation, so that data errors and repeated measurement are brought.

The reason why the tape head needs to be switched to measure the circumference is that the linear tape needs to be changed into a ring shape when the tape head measures the circumference, and the tape head needs to be pulled out for a certain distance and then connected and fixed with a certain area of a product to form the ring-shaped tape. And because the connecting structure position of the digital flexible rule cannot be overlapped with the position of the tape outlet, the difference between the length of the tape drawn out and the real perimeter of the measured object is generated because the annular connecting position of the head and the tail of the tape is staggered after the tape head of the flexible rule is fixed into the annular flexible rule. The digital display flexible rule products in the market at present are distinguished by the functions of the products, so that the linear measurement mode and the circumference measurement mode are distinguished, the circumference measurement mode is obtained by adding the difference to the numerical value in the linear measurement mode, and the numerical value obtained by measuring the articles with the same length in two different modes is different. In addition, due to the difference between the measurement results of the two functional modes, the switching operation of the two functional modes is forgotten by the market during the actual use, thereby bringing various troubles. In the circumferential measurement, because the surface of the shell is in contact with the measured object at a certain distance, the shape of the shell is fixed, and the hardness of the surface of the measured object is different, the obtained measured value has certain difference, so that the applicable market is narrowed. The digital display flexible rule belt head on the market is also because of the problem of this grafting tension or loose too in the dismouting operation, often brings the inconvenience in the operation experience for the user.
