A high-strength multifunctional safety protection door

Abstract

The invention relates to a high-strength multifunctional safe protective door and belongs to the technical field of safe protective equipment. The high-strength multifunctional safe protective door comprises a C-shaped upper side frame body, protective door bodies and a lower side frame body. A convex-upward sliding rail is arranged at the bottom of the upper side frame body; the number of the protective door bodies is two, and sliding mechanisms capable of sliding along the sliding rail are fixedly arranged on the upper sides of the protective door bodies; and a driving mechanism pulling the sliding mechanisms is arranged inside the upper side frame body. The driving mechanism comprises annular gear strips. When the annular gear strips rotate, the motion directions of the upper layer and the lower layer of the annular gear strips are opposite. The upper layer and the lower layer of the annular gear strips are fixedly connected with an upper connecting frame and a lower connecting frame correspondingly, and the upper connecting frame and the lower connecting frame are fixedly connected with the sliding mechanisms corresponding to the protective door bodies correspondingly. According to the technical scheme, the driving mechanism adopts gear strip to conduct transmission, the situation that in the rotating process of the annular gear strips, the rotating directions of the upper layer and the lower layer are opposite is utilized, and the upper layer and the lower layer of the annular gear strips are connected with the connecting frames correspondingly, so that the corresponding protective door bodies are driven to conduct opening motion or closing motion, and the opening mode of the protective door bodies is more flexible.

Description

technical field [0001] The invention relates to a high-strength multifunctional safety protective door, which belongs to the technical field of security equipment. Background technique [0002] The protective door is a door structure used to place heavy objects for impact and damage, and is generally made of high-strength steel. In the prior art, the detention centers under the jurisdiction of the public security, security, and military forces are used for the doors of the detainees' living rooms leading to the management passages and outdoor playgrounds. The doors can resist opening by abnormal means within a specified time. Class doors are also mostly made of protective doors. However, most of the existing protective doors adopt a sliding on one side and a fixed opening on the other side. This method has the problems of slow opening and closing speed and high operating noise. Contents of the invention [0003] In order to solve the problems existing in the prior art, t...
