AI Technical Summary
Technical Problem
现有的双层顶棚结构在滚塑成型过程中，由于内外层材料冷却收缩不一致，易导致顶棚表面出现凹陷的现象，尤其是，双层顶棚内层表面的中间区域，没有顶棚的周侧区域强度高，容易凹陷并与外层贴合粘连，影响外观质量与结构强度
Benefits of technology
本实用新型可通过凸台结构的设计，来对外层进行支撑，具体的，在滚塑成型的冷却阶段，一旦外层的内表面产生凹陷的趋势，凸台结构上的抵接面便会与所述外层的内表面部分粘连抵接，以使所述外层维持与所述内层呈设定高度的状态。

Abstract
The utility model discloses a kind of anti-dimple double-layer cover-like ceiling housings of rotational moulding, including inner layer and outer layer, the inner layer with the outer layer is formed by rotational moulding integrated type to form a housing structure, there is a sealed interval chamber between inner layer and outer layer in the housing structure;The inner layer and the outer layer are all with shell top area and shell edge area, the shell edge area is arranged around the shell top area;In the cooling stage of rotational moulding, once the inner surface of outer layer appears the tendency of dimple, the abutment surface on boss structure will be partially adhered to the inner surface of this outer layer abutment, so as to maintain the set height between outer layer and inner layer.
