    1.测量功能

    1. Measurement function

    我们知道,在弹性限度内,弹簧的伸长(或收缩)跟外力成正比。利用弹簧这一性质制成弹簧秤。

    We know that within the elastic limit, the elongation (or contraction) of the spring is directly proportional to the external force. The spring scale is made by using the property of spring.

    2.紧压功能

    2. Compression function

    不雅观察各种电器开关会发现,开关的两个触头中,必然有一个出头装有弹簧,以保证两个出头紧密接触,是导通良好。如果接触不良,接触处的电阻变大,电流通过时产生的热量变大,严重时还会是接触处的金属融化。卡口灯头的两个金属柱都装有弹簧也是为了接触良好;至于螺口灯头的中心金属片以及所有插座的接插金属片都是簧片,其功能都是使双方紧密接触,以保持到同良好。在盒式磁带中,有一块磷青铜的簧片,利用它弯曲形变时产生的弹力使磁头与磁带密切接触。在订书机中有一个长螺旋弹簧它的作用一方面是顶紧钉书钉,另一方面是当最前面的钉被推出后,可以将后面的钉送到最前面以备钉舒适推出,这样,就能自动的将一个个钉推到最前面,直到钉全部推出为止。许多机器自动供料,自动步枪中的子弹自动上膛都靠弹簧的这种功能。此外,象夹衣服的夹子,圆珠笔,钢笔套上的夹片都利用弹簧的紧压功能夹在衣服上。

    Observing various electrical switches, it can be found that one of the two contacts of the switch must be equipped with a spring to ensure that the two contacts are in close contact and have good conduction. If the contact is not good, the resistance at the contact will increase, the heat generated by the current will increase, and in serious cases, the metal at the contact will melt. The two metal pillars of bayonet lamp holder are equipped with springs to ensure good contact; as for the central metal sheet of screw lamp cap and all socket metal plates, they are spring plates, and their function is to keep both sides in close contact so as to maintain good contact. In a cassette tape, there is a reed of phosphor bronze, which makes the magnetic head in close contact with the tape by the elastic force produced by its bending deformation. There is a long spiral spring in the stapler. On the one hand, it is used to tighten the staples. On the other hand, when the front nail is pushed out, the back nail can be sent to the front for comfortable pushing out. In this way, one nail can be pushed to the front automatically until all the nails are pushed out. Many machines feed automatically, and the automatic loading of bullets in automatic rifles relies on the function of springs. In addition, like clip for clothes, ball point pen and clip on pen cover are clamped on clothes by spring compression function.

    3.复位功能

    3. Reset function

    弹簧在外力作用下发生形变,撤去外力后,弹簧就能恢复状态。很多工具和设备都是利用弹簧这一性质来复位的。例如,许多建筑物大门的合页上都装了复位弹簧人们进出后,门会自动复位。人们还利用这一功能制成了自动伞、自动铅笔等用品,十分便当。此外,各种按钮和按键也少不了复位弹簧。

    The spring deforms under the action of external force, and the spring can recover after the external force is removed. Many tools and equipment use the spring to reset. For example, the hinges of many building doors are equipped with reset springs, and the doors will reset automatically after people enter and leave. People also make use of this function to make automatic umbrella, automatic pencil and other supplies, very convenient. In addition, all kinds of buttons and buttons also need a return spring.

    4.带动功能

    4. Driving function

    机械钟表,发条玩具都是靠上紧发条带动。当发条被上紧时发条产生弯曲形变,存储必然的弹性势能。释放后,弹性势能转变为动能,通过传动装置带动转动。在玩具枪和发令枪和军用枪支也是利用弹簧的之一性质工作的。

    Mechanical clocks and clocks, spring toys are driven by tightening the spring. When the spring is tightened, the spring will produce bending deformation and store a certain elastic potential energy. After release, the elastic potential energy is converted into kinetic energy, which is driven by the transmission device. Toy guns and starting guns and military guns are also used to work with one of the properties of springs.

    5.缓冲功能

    5. Buffer function

    在机车汽车车架与车轮之间装有弹簧,利用弹簧的弹性来减缓车辆的波动。

    A spring is installed between the frame and the wheel of the locomotive and the vehicle. The elasticity of the spring is used to slow down the bumping of the vehicle.

    6.振动发声功能

    6. Vibration sound production function

    当空气从口琴,手风琴中的簧孔中流动时,冲击簧片,簧片震动发出声音。

    When air flows through the holes in the harmonica and accordion, it strikes the reeds and vibrates and makes a sound.
