Tape measure is a commonly used length measuring tool in daily life, and 85% of tape measures in the world are produced and exported from China. The two main types that people often come into contact with are leather tape measures and steel tape measures. There are different lengths of leather tape measures, and long ones are generally used in engineering, with a length of up to tens of meters. Short leather tape measures are mainly used in the garment industry and daily life, mainly for measuring body size, waist circumference, etc. Steel tape measures are mainly used in construction and decoration, and are also one of the essential tools for families.
tape measure
Fiber tape measure, also known as leather tape measure, is commonly seen. Many people refer to it as a fabric tape measure, and there are also waist tape measures (such as tailor tape and measuring tape). In the southern regions of China and Hong Kong, a tape measure is commonly referred to as a tape measure or a tape measure. Its material is PVC plastic and fiberglass, which can prevent the tape measure from being stretched during use.
A tape measure, usually in metric and imperial systems, is 150 centimeters on one side and 60 inches on the other side. Inch is a commonly used unit of measurement abroad, with one inch=25.4 centimeters. The unit of measurement for televisions and monitors is inches, usually referring to the diagonal length. The size of jeans is also inches. In China, the commonly used measuring tape for clothing is the market size. One side is 150 centimeters, and the other side is 45 inches. The commonly referred to 2 feet 1 and 2 feet 2 waist are units of market size. One foot equals ten inches, and one meter equals three feet, so one square inch equals 3.333 centimeters.
steel tape measure
The main types of tape measures are steel tape measures, Luban tape measures, Feng Shui tape measures, and Wengong tape measures, all of which belong to steel tape measures. The front of a steel tape measure usually has two scale bars, with the upper part in inches and the lower part in meters, which are commonly used in China. Conventional lengths include 3m, 5m, 10m, etc. Nowadays, the traditional Luban tape measure has been incorporated into a new type of Luban tape measure, incorporating the Eight Characters to measure the auspiciousness and inauspiciousness of houses. Working principle of curling
The reason why the tape measure can be rolled up is because it contains a spring. When pulling out the measuring length, it actually elongates the length of the ruler and spring. Once the measurement is completed, the spring inside the tape measure will automatically contract, and the ruler will also contract under the force of the spring, so the tape measure will be rolled up. Usually, there is a hook at the front end of the tape measure for positioning during measurement.
Interesting design intention
There are some seemingly strange but actually very interesting designs on the tape measure, but we just don’t understand their true purpose. Here, the author would like to share with readers some interesting designs on tape measures.
- There is a hole at the hook of the tape measure
If observant readers have carefully observed the tape measure, they will find a hole at the hook of the tape measure. So what is its purpose? The following picture will make you suddenly realize. That’s right, it can be stuck on a nail like this, and then you don’t need another hand or someone to fix the tape measure for you. This design can greatly improve measurement efficiency without the need for particularly precise measurements. - The edge of the tape measure hook is not flat, but has teeth
Its use is when you need to draw a line at the measurement location and don’t have a pen in your hand. Hold it down and rub it a few times at the position where you need to draw a line to help you identify it. - What is the function of the back buckle on the tape measure?
Like many old-fashioned keychains, the back buckle on the tape measure is mainly used for carrying. At many construction and measurement sites, operators can directly hang their belts or pockets after the measurement is completed, and then continue with other operations. When used again, it can be taken as needed, convenient and fast. - What is the purpose of the numbers on the outer shell of the tape measure case?
We often see numbers on the shell of a tape measure, but we don’t know its purpose. For example, this tape measure is labeled with the number 58mm. So what is its purpose? Actually, it represents the length of the tape measure casing.
Many designs that we think are unnecessary actually contain the designer’s good intentions and secrets. The design of the tape measure is far more magical than we imagined.
