[0041] The setting temperature of the deep-freezing refrigerator chamber is usually lower than -30℃. When storing articles, a drawer type storage box is usually used. A slide rail is a commonly used moving component for assisting the sliding of the drawer in and out. When the volume of the drawer is large, a metal slide rail is usually used. However, when the metal slide rail is used in a cold storage device, the space in the refrigerator is communicated with the external environment after the refrigerator door is opened. The humid and hot air in the external environment is easy to enter the refrigerator. The humid and hot air causes the surface of the metal slide rail to be easy to frost. Especially after the slide rail is repeatedly slid during the pushing and pulling of the drawer, the frost in the gap between the metal components is repeatedly crushed to form hard ice crystals. This causes the user to have difficulty in pushing and pulling the drawer and affects the use of the user.
