Abstract
Description
Technical Field
[0001] The utility model belongs to the field of one-way revolving doors, and particularly relates to an improved electric one-way revolving door. Background Art
[0002] In crowded areas such as public buildings, commercial centers, and large office spaces, revolving doors are usually used as access channels to effectively manage and control the flow of people. Revolving doors can not only isolate the external environment, maintain indoor temperature and cleanliness, but also play a role in security prevention to a certain extent. Traditional revolving doors are mostly designed for two-way passage, that is, people are allowed to freely enter and exit in both directions. However, in certain specific occasions, such as railway stations, revolving doors also need to have the function of one-way passage to prevent passengers from passing items without security inspection.
[0003] Currently, the driving mechanism of one-way revolving doors mainly includes a motor, a reducer, and a gear transmission structure. The motor drives the revolving door body to rotate through the reducer and the gear transmission structure. When there is a power failure or other situations where pedestrians need to push the revolving door body, due to the limitation of the transmission ratio of the transmission structure, pedestrians need to apply a very large force to the revolving door body to make it rotate, which causes great inconvenience to pedestrians. At the same time, due to the small size of the gears inside the reducer, when pedestrians push the revolving door body, the power is transmitted to the reducer and easily causes damage to the internal gears. This not only increases the maintenance cost but also affects the service life of the revolving door.
[0004] Therefore, based on the above situations in the prior art, this application has been further designed and improved. Content of the Utility Model

[0029] The distinguishing features of the present utility model from the prior art are as follows: The linkage mechanism 40 is driven by a reduction motor 50. An electromagnetic clutch 51 is connected to the output shaft of the reduction motor 50. The electromagnetic clutch 51 is connected to a clutch shaft 52. A driving gear 53 is assembled on the clutch shaft 52. The linkage mechanism 40 includes a third gear 48 meshed with the driving gear 53. In the present utility model, the reduction motor 50 drives the rotation of the revolving door body 20, and the rotation of the revolving door body 20 can drive the movement of the one-way door body 30 through the linkage mechanism 40. When the one-way door body 30 is closed, it can block the exit or entrance on the side of the reverse area. When a pedestrian pushes the revolving door body 20, the electromagnetic clutch 51 disconnects the connection between the reduction motor 50 and the clutch shaft 52 to protect the reduction motor 50. The function of this design is to facilitate pedestrians to push the revolving door body 20 and effectively avoid the problem of internal damage to the reduction motor 50 caused by pedestrians pushing the revolving door body 20.
[0030] In the present utility model, the revolving door body 20 includes a rotating shaft 21, and a plurality of door panels 22 are annularly distributed on the rotating shaft 21. The door panel 22 of the revolving door body 20 includes a door frame 23, and a glass plate 24 is assembled in the door frame 23, making the inside of the revolving door bright and well-lit, avoiding the discomfort of being dark and narrow. The door frame 23 is made of aluminum profiles to reduce the weight of the door panel 22. The glass plate 24 is laminated glass. Even if the glass is broken, the fragments will be adhered to the film, and the surface of the broken glass remains clean and smooth. It effectively prevents the occurrence of events such as fragments stabbing and penetrating and falling, ensuring personal safety. The one-way door body 30 includes a rolling door shaft 31, and a rolling curtain 32 is installed on the rolling door shaft 31. A door head plate 33 for pulling is assembled at the head end of the rolling curtain 32, and the door head plate 33 is connected to the linkage mechanism 40. The door head plate 33 covers the head end of the rolling curtain 32 for pulling in the vertical direction to ensure that the upper and lower sides of the head end of the rolling curtain 32 can move synchronously.
[0031] Specifically, in the present utility model, the linkage mechanism 40 includes a first gear 41 and a second gear 42 that mesh with each other. The first gear 41 is assembled with the rotating shaft 21 of the revolving door body 20. The second gear 42 and the third gear 48 are assembled on an intermediate shaft. A connecting rod seat 43 is also assembled on the intermediate shaft. A first connecting rod 44 is assembled on the connecting rod seat 43.

Under this structural design, the rotation of the revolving door body 20 can be converted into the linear movement of the sliding seat 46 in the limiting slideway 47.
[0032] The working principle of the one-way passage of the present utility model is specifically as follows: The reduction motor 50 drives the rotation of the rotating door body 20 through the linkage mechanism 40, and the rolling curtain 32 reciprocates linearly. When the door panel 22 of the rotating door body 20 rotates to the area where the rolling curtain 32 is located, the rolling curtain 32 is retracted to the rolling door shaft 31. At this time, the one-way door body 30 is in a fully open state to facilitate the passage of the door panel 22. After the door panel 22 passes, the rolling curtain 32 gradually unfolds under the drive of the linkage mechanism 40. After the head end of the rolling curtain 32 approaches or reaches the rotating shaft 21 of the rotating door body 20, it gradually retracts until the next door panel 22 rotates to the area where the rolling curtain 32 is located. The continuous movement process of the rolling curtain 32 gradually unfolding and then gradually retracting occurs in the area between two adjacent door panels 22 in the reverse area, so that the space in this area is always restricted or separated by the rolling curtain 32 and cannot accommodate pedestrians or items.
