Ruima-The two-wing revolving door featuring display case retraction and anti-pinch [standard]
Safety accident caused by improper use of revolving door
The principle and demonstration of the retraction function of the display case to solve the pinching at the entrance
Architecture is a solidified art, a note of the city, and also a concentrated area of urban people flow. The main entrance of the building is an area with relatively concentrated people flow. Therefore, access safety has become the most important basic premise. At the same time, people's contact with the building starts from the entrance, so the entrance and exit is also known as the business card of the building. The sensory effect and safe and comfortable passing experience brought by a safe and gorgeous door have made the finishing touch of the architectural impression.

Life is irreversible and safety is irreplaceable!
The conventional revolving door has natural structural defects, which will cause the potential hazard of user being stuck
As revolving doors are used as civil access equipment in daily use, safety is a key factor that cannot be ignored. According to the requirements specified in GB General Technical Requirements of Pedestrian Automatic Doors, during the operation of the two-wing revolving door, when the distance between the front stile of the two-wing door display case and the right column frame of the door is 500mm, if someone forces an entry at this time, it is easy to cause collision and pinching injury between the front stile of the two-wing door display case and the column.
Principle analysis of accident
During the normal operation of the revolving door, there is a sliding distance from the beginning of braking to the complete stop of the door, which is defined as the braking distance in GB. When the passage space of the entrance is less than the braking distance, if someone still rushes into the door, even if the revolving door brakes immediately, it is impossible to avoid squeezing users into the gap of the curved wall, resulting in pinching injury. This is an objective fact caused by the structural defects of the conventional revolving door, which has nothing to do with the safety arrangement of the revolving door.
If the structure of the entrance does not change, any safety protection will not solve this potential hazard.
The retraction technology of SOTC display case has overcome the potential hazard of being struck
China's first industry-leading safety upgrade
At present, the conventional automatic revolving door on the market usually installs an anti-pinch sensor at the front edge of the door in order to solve the potential hazard of being struck in the rotation itself - when someone is squeezed by the door leaf, the anti-pinch sensor transmits the signal to the controller, and then controls the door leaf to stop rotating, so that users can get out in time. However, in the actual use process, due to the large weight of the display case and its motion inertia, the controller controls the door leaf to stop, and the rear door leaf can still continue to rotate for a certain distance, so as to further squeeze the body and cause more serious injury; in addition, the sensing accuracy of the anti-pinch sensor is seriously affected by the difference of time and distance. Once the anti-pinch sensor fails or the user is outside the sensing range, such as a child being struck and the door leaf continues to rotate, pinching injury or even death will occur.
金年会体育 Technology always adheres to the core concept of "Safety • Product". The retraction function of the display case, which has been developed for five years, solves the problem that the "rush" of users causes them to be stuck into the gap between the display case and the column according to GB General Technical Requirements of Pedestrian Automatic Doors from a mechanical point of view through the principle of space avoidance, resulting in pinching injury to users. When users force an entry, the pressure-sensitive sensor installed at the front stile of the display case (the trigger range is from the ground to a height of 2m above the ground) or other sensors will trigger the automatic retraction of the display case, resulting in a 280mm safe avoidance gap. Once the danger has passed, the display case will reset automatically. We have applied for an invention patent for this function to China National Intellectual Property Administration (ZL 201910140982.7).
Anti-pinch principle of the two-wing door with retraction of display case
The two-wing automatic revolving door featuring display case retraction and anti-pinch is not only compatible with the characteristics of the original revolving door, but also has a qualitative "leap" in the safety function. This patented product adopts the innovative design of mechanical structure and intelligent frequency conversion control technology. Through the inlet rubber extrusion trigger switch with double trigger function (the trigger range is from the ground to a height of 2m above the ground) developed and installed on the front stile and column of the display case, it ensures that the 180 ° sensitive trigger has no dead angle, and ensures that the display case automatically retracts and generates a safety gap when it encounters dangerous contact pressure, which fundamentally solves the potential hazard of being stuck between the curved wall and the outer arc wall of the display case of the revolving door!
