The structure of the two-wing revolving door is intuitively composed of two parts: the outer fixed curved wall and the inner rotating body.

In practical application, if the inner rotating body can rotate, it must maintain a certain clearance distance from the outer curved wall. The national standard stipulates that the clearance should be less than 8mm or greater than 25mm. Therefore, the normal clearance of the revolving door manufacturer is about 40mm, and it is sealed with a brush. .

When the inner swivel rotates to a position that coincides with the outer curved wall, a scissors effect will occur. Because of this structural feature, it also leaves a potential safety hazard in daily use. In the national standard, the places that cannot be solved by current technology and there are potential safety hazards are designated as dangerous areas, so that everyone can take precautions in advance, but in real life, there are very few people who really know where the revolving door is dangerous. At present, for the main dangerous area of ​​the entrance, a prevention-oriented safety protection scheme is adopted, and a safer anti-pinch sensor is set on the revolving door configuration, which makes the safety factor higher. But the problem in fact is that no matter how scientific and meticulous the safety sensor settings are, there will be helpless special situations. Just like a normal driving car, if there are pedestrians or objects outside the braking distance, they can brake in advance to prevent accidents. However, if a pedestrian suddenly appears within the braking distance, no matter how sensitive the braking is, the accident cannot be avoided. This is There are objective facts that are very helpless. In the same way, we all know that there is no danger in the normal use of the revolving door, but if the revolving door is forced into the door when the door is closed, even if the revolving door brakes immediately, it will be caused by inertia after braking. The sliding distance (the normal braking distance that meets the standard is about 100mm, and the braking distance that does not meet the standard may be about 200mm or even greater), people are squeezed into the narrow gap of 40mm between the curved wall and the outer curved wall of the exhibition box, causing damage to the equipment. In an accident involving serious pedestrian injury, the revolving door must be demolished in order to save people, resulting in loss of life and property. These problems generally occur in children, the elderly, or drunk adults who pass through abnormally. With the popularity of revolving doors, such accidents are on the rise.

Because of the preciousness of life, even if there is a probability of 1 in 1,000 or 1 in 10,000 accidents, we cannot take chances and should use safer technology products to avoid such tragedies.

The retraction function of the display box of Ruize SOTC adopts "frequency conversion technology + innovative design of mechanical structure", which completely solves this hidden safety problem from the structure. The retraction function of the exhibition box is to design the "mistake-safety" function for the revolving door. Even if it encounters abnormal pedestrians, the retraction space of the exhibition box will expand, and the innovative structure of the product itself will no longer cause danger to pedestrians, making hidden dangers. Completely disappeared, ensuring the safety of pedestrians.

Ruize advocates: use revolving doors, use safe revolving doors!
