High Performance Pvc Rubber Tape Measure

High Performance Pvc Rubber Tape Measure from China factory

It can be said that the tape measure from China factory is the most commonly used and important measuring tool. Because of its simple structure and convenient use, almost everyone has used it. Basically, you can find a common tape measure at home. There may be some secrets you don’t know.

1. What do the Roman numerals on the front of the tape measure mean?

If you look carefully, you will see that the Roman numeral 1 or 2 is printed on the head of some tapes. This represents the two accuracy levels of the tape, and the first level is the highest.

2. Why is the tape hook loose?

When you use a steel tape designed from china manufacturer, you will find that the hook on the head of the tape is loose. At first, you thought it was caused by the loosening of the rivets due to the long use of the tape measure. Later, you bought a new steel tape designed from china, and the same problem will occur. At that time, you were curious about why this happened? In fact, this is the unique design of the tape, and it is also a function of the tape measurement. The purpose is to make the tape measurement more accurate. If you look at the tape carefully, you will notice that the first centimeter of the tape is less than all the other centimetres. When measuring the internal dimension, the hook head is against the outside of the hook as the starting point, and when measuring the external dimension, the internal measurement of the hook as the starting point, so the hook looseness is to fill that millimeter, This eliminates the measurement error caused by the hook thickness and makes the steel tape designed from china more accurate.

3. What’s the use of the numbers on the ruler shell?

A few numbers are often seen on the back of the shell of the tape measure. In fact, few people will pay attention to it, and they don’t know what it means. In fact, this print is the size of the shell, so what’s the use? When an internal measurement corner is encountered in the measurement, the ruler belt is usually pulled to the corner. At this time, the ruler belt is bent, so the measurement reading is obviously inaccurate. The tape designer has considered this problem. The correct approach is not to bend the ruler belt, as long as the ruler shell is close to the plane of the corner. The reading is the length of the exposed ruler belt plus the size printed on the ruler shell. This approach can also prevent repeated bending of the ruler belt, This will cause damage and wear.

4. What’s the use of the hole on the hook?

Some tape measure hooks have a round hole, which is not made to reduce the material cost. Its function is to directly hang the nail or bulge when measuring, and the tooth hook will not fall off easily.

5. What is the function of hook belt serration?

When you need to mark the measured data with a tape measure from supplier, if you don’t have a pen in your hand, you can use the serration on the hook to make a few strokes.

6. Why is the ruler band curved?

The edge of the tape will be upturned, so why not make it into a horizontal tape? This is mainly to increase the stretching strength of the tape. In the standard, it is called the straightness of the tape. This arc makes the tape longer without losing strength. The wider the tape, the longer the straightness.

I didn’t expect that there are so many small secrets in the small tape measure. Is it strange that the knowledge has increased again

Steel tape measure is loose how to put back

Tape measure is a very common tool in life, but we often find it difficult to understand many of its designs when using a tape measure, in fact, every seemingly strange design on the tape measure is not chicken, we just do not understand their true usefulness, many families basically have a tape measure, tape measure in daily life application scenarios are very much, is difficult to indispensable in every family Basic tools, and for workers in certain industries, such as the construction industry, tape measure is an essential tool.
1. fix one end of the spring on the shaft, the other end connected to the tape measure core, fixed with the shaft of the tape measure shell.
2. Wrap the spring sheet and the ruler core in a circle on the shaft, wrap the outer end of the ruler core from the cutout of the ruler shell, and gently pull outward to make the spring tight.
3.Take off the pulled part from the cutout and wrap it on the shaft again, then gently pull it outward again, then take out the ruler core from the cutout and wrap it on the shaft, so on and so forth until the spring is enough to take back all the ruler cores, then put the cotter pin on the center shaft, put on the cover, and will tighten the screws.
