Details
The spring structure of the glasses box is composed of an upper cover, a lower cover, an intermediate partition and a spring. The upper cover and the lower cover are designed to be turned over, which is convenient to use. The middle partition is used to separate the upper and lower storage spaces, and the spring is used to connect the upper cover and the lower cover, so that the box has a rebound function. The main function of the spring structure of the glasses box is to make the box have a rebound function, which can prevent the problem that the box cannot be closed or is easy to relax after it is opened. At the same time, the spring can also provide appropriate pressure to make the box tighter, prevent dust and debris from entering the box, and protect the cleanliness of the glasses.
