60s: I have a store

Chapter 286 Test
Zhou Yimin was waiting here, and in less than an hour, Master Kong made the reel.

It can only be said that it is worthy of being a hand-made aircraft carrier. It can be made with just Zhou Yimin's rough description.

Master Kong said confidently: "Section Chief Zhou, take a look, is this what you want?"

Zhou Yimin observed it carefully and tried it with some cloth strips. It was indeed similar to the reel of later generations, although the appearance might be different. For this reel, Master Kong also used mortise and tenon structure.

"Master Kong, you are worthy of being a master. The things you make are great." Zhou Yimin gave a thumbs up.

Master Kong said modestly: "That's just that this retractor is simple. If it were a little more difficult, it would definitely not be so easy."

But it's also true, if you draw the picture, even a fourth or fifth level fitter can make it.

Zhou Yimin thanked him and left with the retractor, heading to the Transportation Department to try and see if it worked.

After arriving at the Transportation Department, Zhou Dafu saw Zhou Yimin and hurriedly stepped forward and asked, "Uncle Sixteen, are you back from your business trip?"

"Yes, I returned last night. Where is Captain Li?" Zhou Yimin replied.

Zhou Dafu said: "Master Li is busy, I will go and call Master Li over for you."

After a while, Chow Tai Fook brought Li Feng over.

Li Feng joked, "Section Chief Zhou, what brings you here today?"

The relationship between the two is pretty good, so there is no problem with making a little joke.

"I came here to invent something that can greatly ensure the safety of drivers in the event of a car accident." Zhou Yimin said directly.

Li Feng did not have the joking attitude at the beginning, but asked seriously: "Section Chief Zhou, are you telling the truth?"

You know, training a driver is a very difficult task. Now, if there is a car accident, there is a high probability that the person will not be saved. Fractures are considered minor injuries among minor injuries.

"Of course it's real. I've already made the thing and now I want to test it on a car. Is that okay?" Zhou Yimin affirmed.

"Yes, of course. You can pick any car here?" Li Feng said excitedly.

Although the car is important, the driver is equally important. Without the driver, the car is useless.

Zhou Yimin did not choose any of the new cars. Instead, he picked one that looked very historic, and pointed at it and said, "Let's take this one!"

"Section Chief Zhou, how about we pick a good one, like a Yellow River brand truck?" Li Feng said directly.

If what Zhou Yimin made is really useful, it can save lives at the critical moment!

Who can guarantee that there will be no accidents in a lifetime of driving? For the sake of his own life, he actively cooperated.

Zhou Yimin smiled and said, "Captain Li, if you believe in what I invented, you won't be afraid that it will just be a showpiece and fail at the critical moment."

Anyway, we are just testing the performance, so there is no need to use a good car. Any one will do. Since Li Feng proposed it personally, we might as well satisfy him and choose his Yellow River truck.

The modification started soon. First, the driver's seat had to be modified. First, a hole was opened, and then the retractor was put in. Another hole was left so that the cloth strip could be pulled out smoothly, and there was a buckle. Under Zhou Yimin's command, Li Feng quickly completed the modification of the truck and started the test.

"Section Chief Zhou, how do we test this? Is it useful?" Li Feng asked puzzled.

It's impossible to deliberately cause a car accident to test whether seat belts are useful, right?
"First, we'll get a dummy, drive the car at maximum speed, and then brake suddenly to see what the difference is between wearing a seat belt and not wearing a seat belt. This way we can intuitively feel whether the seat belts are useful," Zhou Yimin suggested.

He also knew that trucks were too important to be deliberately collided, and he knew that no one would be willing to test the seat belt with their own life, and his superiors would agree to take risks with the factory's precious assets.

Li Feng exclaimed: "Good idea."

He immediately began to test it. Li Feng tried bravely on his own. First, he made a scarecrow with some straw, and then installed some scrap iron on the scarecrow to make it have the weight of an adult, so that the test would be rigorous.

The first test is with the seat belts fastened.

Li Feng drove the truck to an open place and started accelerating. After accelerating for a distance, he soon reached a speed of about 70 kilometers per hour, which was the maximum speed of the truck.

Then he started to brake suddenly, and Li Feng stepped on the brake pedal hard.

The truck's braking system started to work, and the tires rubbed against the road violently, leaving four black brake marks.

You can imagine how intense the braking was.

Li Feng and the scarecrow were both firmly fixed on their seats by the seat belts on both sides. Except for the fact that their bodies leaned forward at the beginning, the seat belts started working and fixed them instantly. Neither the man nor the scarecrow flew out.

Li Feng was also frightened by this scene. At first he thought that the person was going to fly out. If it was a truck without a seat belt, the person would have flown out long ago. He did not expect that the seat belt was so powerful. Now, except for a little pain in his chest, there was no other problem.

"Captain Zhou, your invention is very useful. On behalf of the Transportation Department, I would like to thank you." Li Feng bowed.

"It's all for serving the people." Zhou Yimin waved his hand.

Immediately afterwards, Li Feng started the second test. This time, Li Feng was wearing a seat belt, while the scarecrow was not, which provided a direct comparison.

As the car speed increased, it soon reached the maximum speed of a truck and began to brake suddenly.

The scarecrow broke through the glass due to inertia and flew out of the car.

However, Li Feng's seat belt broke directly due to inertia, and his chest hit the steering wheel directly, instead of flying out of the car like a scarecrow.

Li Feng and Zhou Dafu, who were present, were also frightened by the scene.

I didn't expect the scarecrow to break through the glass and fly out directly. You know, the glass of the truck is very hard, unlike the glass used at home, which will break if hit.

Even if you use a hammer to hit the truck glass, it will take at least many hits before it breaks. But if you want to hit it into this state, I don’t know how long it will take to reach this level.

Li Feng was so frightened that his legs went weak, but he still pretended to be calm and rubbed his chest, pretending to have chest pain. He said, "Section Chief Zhou, this safety belt you invented is really useful. But it's too fragile. It broke after two uses."

If it breaks at the critical moment, wouldn't it be almost the same as not having any connection at all?
Therefore, the materials must be strengthened.
