Do not say that there are many obstacles in the mountains, the wind is strong and the wind is strong, and the clouds can pass through the mountains. Don’t say that the water is variable, and the water is also clear and quiet. The tenderness is like water love forever, but I am afraid that the wind will blow away the love, Love and passion.

The extension spring is a coil spring that bears axial tension, also called extension spring. Tension springs are usually made of circular cross-section materials. When the load is not accepted, there is usually no gap between the tension spring rings.

The tension spring acts in reverse when it is stretched or pulled apart. When both ends of the tension spring are pulled apart, many different end devices or "hooks" are used to ensure the source of tension of the tension spring. The working principle of tension spring is opposite to compression spring. The compression spring acts in reverse when compressed. Spring will try to pull him back. Like compression springs, tension springs also absorb and store energy. But unlike compression springs, most tension springs are usually at a certain level of tension, even without any load. This initial tension determines the tension level of the tension spring coil without any load.

Extension springs are also called spiral extension springs. The cross section is mostly circular, which can be widely used in production and assembly, experiment, research and development, maintenance and other fields. Springs occupy an important position in the global market, and are widely used in national defense, marine, computers, electronics, automobiles, molds, medicine, biochemistry, aerospace, railways, nuclear power, wind power, thermal power, engineering machinery, mining machinery, engineering machinery, elevators And other fields.

Thousands of waters and mountains are always in love, remember not to forget to stretch the spring, Hong Sheng walks with you.
