The utility model relates to security door technical field especially is a kind of steel security door of collision resistance, including door body and the door lock being installed on door body, and door body includes inner layer steel sheet and outer layer steel sheet, and inner layer steel sheet and outer layer steel sheet are connected with intermediate filling layer;Intermediate filling layer includes outer reinforcing main part, and outer reinforcing main part is fixedly connected between inner layer steel sheet and outer layer steel sheet, and outer reinforcing main part is in middle part and is equipped with collision resistance filling interlayer, and the outer surface edge of collision resistance filling interlayer is fixedly connected with the reinforcing rib of multiple equidistance distribution.The utility model described a kind of steel security door of collision resistance, through multilayer composite structure design, effectively promote the impact resistance, pry and fireproof performance of door body;The combination of honeycomb aluminum plate and fireproof plate enhances energy-absorbing shock absorption and heat insulation effect, and the reinforcing rib structure of door lock area improves overall security and durability, applicable to a variety of high security demand place.

A multifunctional doorbell waterproof cover relates to the technical field of doorbell equipment. The rotary rain eyebrow comprises a doorbell mounting seat and a rotary rain eyebrow, the rotary rain eyebrow is movably connected with the doorbell mounting seat through a rotating shaft buckle, a solar panel is obliquely arranged on the upper portion of the doorbell mounting seat, and a water drop sensing mechanism and an illumination sensing mechanism are arranged on the top of the doorbell mounting seat. The upper part of the doorbell mounting seat is also provided with a control main board which is electrically connected with the solar panel, the water drop sensing mechanism and the illumination sensing mechanism, and the doorbell can be better protected under different rainfall conditions through the arrangement of an adjustable shielding cover, and the functions of rainfall sensing and illumination sensing are set at the same time. A user can better adjust the shielding cover according to weather conditions, and the doorbell can be powered by solar energy, so that the doorbell can still be used when no power is supplied, and better use experience is brought to the user.
