Description

Technical Field

[0001] The utility model belongs to the technical field of automatic revolving doors, and particularly relates to an automatic revolving door with an anti-pinch structure. Background Art

[0002] Automatic revolving door is a modern entrance device, widely used in commercial buildings, hotels, banks, hospitals and other places. It uses an electric motor to drive the door body to rotate automatically around the vertical axis, allowing pedestrians to enter and exit easily. At the same time, it can effectively isolate the temperature difference between indoor and outdoor, maintain the comfort of the building's internal environment and save energy. The automatic revolving door is always in a rotating state during use, and teenagers and adults need to follow the automatic revolving door when passing through it, and the speed needs to be not much different from the rotation speed, otherwise they will be hit by the back side of the automatic revolving door or hit the front side of the automatic revolving door. In addition, when entering and exiting the automatic revolving door, if the speed is too slow or when passing through the current entrance and exit quickly, it is very easy to be pinched by the automatic revolving door, which will cause pinching problems for teenagers and adults.

[0003] Secondly, most common automatic revolving doors use sensors to prevent pinching. The setting of the sensors has a certain lag and cannot solve the pinching problem that has already occurred, resulting in the unavoidable pinching injury to users.

[0004] In summary, the automatic revolving door without an anti-pinch structure has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content

When clamping occurs, a thrust is generated on the soft outer pad, causing the anti-pinch spring to be continuously compressed and the damping telescopic rod to be continuously shortened, thereby reducing the clamping force on passers-by.

[0010] As a preferred embodiment, a trigger metal column 1 for controlling the reverse rotation of the motor is provided at the center of the side surface of one end of the outer extension end close to the central rotating shaft;

[0011] A second triggering metal column is provided on the inner side of one end of the anti-pinch mechanism groove away from the central rotating shaft. The second triggering metal column is connected to the external motor module through a wire. The continuous compression of the anti-pinch spring and the continuous shortening of the damping telescopic rod will cause the first triggering metal column to contact the second triggering metal column, thereby causing the motor module to control the motor to reverse and rescue the clamped person.

[0012] As a preferred embodiment, the side of the outer mounting frame away from the central rotating shaft is provided with a mounting groove, and the left and right sides of the outer mounting frame and the single door assembly close to the central rotating shaft are provided with mounting threaded holes at both ends;

[0013] The single door component is embedded in the installation groove at one end close to the central rotating shaft and is connected and fixed by screwing bolts into the inner side of the installation threaded hole. The single door component is embedded in the inner side of the installation groove and is connected and fixed by screwing bolts into the inner side of the installation threaded hole. The single door component can be disassembled separately.

[0014] As a preferred embodiment, the disassembly member is provided with an engaging slider at one end close to the central rotating shaft, the engaging slider is engaged with the anti-pinch sliding groove, and the disassembly member is provided with a limit plate at one end away from the central rotating shaft;
