Description

Lifting rib, preparation method thereof and clothes drying device using lifting rib Technical Field The invention relates to the technical field of clothes drying devices, in particular to a lifting rib, a preparation method thereof and a clothes drying device using the lifting rib. Background With the improvement of life quality of people, more requirements are put on the improvement of household appliance noise. The existing clothes dryer lifting ribs are made of single-layer injection-molded polymer materials, irregular impact surfaces of foreign matters such as zipper buttons on clothes can generate larger impact abnormal sounds, scratches and stress impact white spots can be formed on the surfaces, and hearing and visual experience of users are seriously affected. In order to solve the problem of scratches on the surface of the lifting rib and the problem of white spots due to stress knocking, some researchers try to punch the lifting rib by using metal, and the metal lifting rib solves the abrasion problem, but has more sharp knocking noise (the knocking noise is increased by more than 5 dB). Secondly, some subsequent problems, such as that the pure metal lifting ribs and the metal cylinder body cannot be effectively connected through screws and a certain assembly gap exists between the pure metal lifting ribs and the metal cylinder body, are brought. Therefore, the metal lifting ribs obviously cannot give consideration to noise reduction, wear resistance of the appearance surface and decoration function characteristics. Therefore, the novel lifting rib is of great significance in order to achieve the functional characteristics of noise reduction and surface wear resistance.
