Abstract
Description
Technical Field
[0001] This utility model relates to the field of disinfection and sterilization equipment technology, specifically a rotating door and disinfection equipment. Background Technology
[0002] Revolving doors are a common opening and closing mechanism in equipment requiring sealed interior spaces, such as disinfection cabinets and laboratory chambers. Traditional revolving doors are mostly manually operated, requiring personnel to directly push and pull the door to open and close. This method has significant shortcomings in practical use: First, manual operation requires direct contact with the door, which can easily lead to cross-contamination in biosafety and cleanroom disinfection scenarios, compromising the sterile or controlled state of the internal environment. Second, manual opening and closing relies on human intervention and cannot be automatically linked with the equipment's disinfection program. For example, it cannot automatically lock during disinfection or automatically open ventilation after disinfection; the timing of operation depends entirely on human judgment, reducing work efficiency and posing a risk of misoperation. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a revolving door and disinfection equipment to solve the problem of cross-infection that is easily caused by manually revolving doors.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a revolving door, comprising a frame, and further comprising a door panel and a drive mechanism both mounted on the frame; the door panel is connected to the drive mechanism via a first connecting member, and the drive mechanism is used to drive the door panel to rotate; The driving mechanism includes a rotating unit; the rotating unit includes a driver, a driving shaft, and a driven shaft. The drive shaft is located at the output end of the driver; the first connector is connected to the drive shaft. The driven shaft is mounted on the frame and is connected to the door panel via a second connector; When the driver rotates, the drive shaft rotates with the driver, the first connector rotates and drives the door panel to rotate, and the second connector drives the driven shaft to rotate.
[0005] As a further improvement of this utility model, the drive mechanism also includes a door opening trigger unit and a door closing trigger unit; The door opening trigger unit includes a first sensing element connected to the drive shaft, and a first sensor corresponding to the first sensing element; The door closing trigger unit includes a second sensing element connected to the driven shaft, and a second sensor corresponding to the second sensing element.
[0006] As a further improvement of this utility model, the first sensing element and the second sensing element are respectively installed at the ends of the drive shaft and the driven shaft; The first sensing element and the second sensing element are detachably connected to the drive shaft and the driven shaft, respectively.
[0007] As a further improvement of this utility model, the first sensing sheet and the second sensing sheet are respectively provided with a first protrusion and a second protrusion in a lateral manner. The first protrusion and the second protrusion are respectively used to cooperate with the first sensor and the second sensor to trigger the door panel's open signal and close signal.
[0008] As a further improvement of this utility model, the first protrusion is located on the path of the first sensing sheet as it rotates with the drive shaft along the door opening direction; The second protrusion is located on the path of the second sensing sheet as it rotates along the closing direction with the driven shaft.
[0009] The beneficial effects of this utility model are that, by setting up a drive mechanism including a driver, a drive shaft, and a driven shaft, the electric drive of the rotating door is realized. The drive shaft is connected to the output end of the driver, and the driving force is transmitted to the door panel through the first connecting member, replacing the manual push-pull operation.

[0012] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0013] Reference Figure 1-3 As shown, a revolving door includes a frame 1, a door panel 2 and a drive mechanism both mounted on the frame 1; the door panel 2 is connected to the drive mechanism via a first connector 3, and the drive mechanism is used to drive the door panel 2 to rotate. The drive mechanism includes a rotating unit; the rotating unit includes a driver 5, a drive shaft 6, and a driven shaft 7; Drive shaft 6 is located at the output end of driver 5; first connector 3 is connected to drive shaft 6. Driven shaft 7 is mounted on frame 1 and is connected to door panel 2 via second connector 4; When the driver 5 rotates, the drive shaft 6 rotates with the driver 5, the first connector 3 rotates and drives the door panel 2 to rotate, and the second connector 4 drives the driven shaft 7 to rotate.
[0014] In this embodiment, the drive mechanism includes a drive shaft 6 and a driven shaft 7. The drive shaft 6 is responsible for transmitting the torque of the driver 5 to the door panel 2 through the first connector 3, while the driven shaft 7 rotates with the door panel 2 through the second connector 4. This layout avoids a single transmission and has a compact structure. The driven shaft 7 can shorten the length of the drive shaft 6, making it easier for the driver 5 to drive and reducing the driving force requirement. The driven shaft 7 can also provide auxiliary support and stabilize the rotation of the door panel 2.
[0015] Preferably, the drive mechanism further includes an opening trigger unit and a closing trigger unit; The door opening trigger unit includes a first sensing element 8 connected to the drive shaft 6, and a first sensor 10 corresponding to the first sensing element 8; The door closing trigger unit includes a second sensing element 9 connected to the driven shaft 7, and a second sensor 11 corresponding to the second sensing element 9.
[0016] In this embodiment, the door opening trigger unit is located on the drive shaft 6, and the door closing trigger unit is located on the driven shaft 7, so that the detection of the door opening and closing states is completed on different axes. Compared with the scheme of installing multiple sensors on the same axis, this avoids structural interference caused by insufficient space, as well as signal interference caused by the coaxial installation of multiple sensors. The sensors on the two axes are triggered independently, and the signals are clear and easy to distinguish, improving the accuracy and reliability of state detection.
[0017] Preferably, the first sensing element 8 and the second sensing element 9 are respectively installed at the ends of the drive shaft 6 and the driven shaft 7; The first sensing element 8 and the second sensing element 9 are detachably connected to the drive shaft 6 and the driven shaft 7, respectively.
[0018] In this embodiment, the first sensing plate 8 and the second sensing plate 9 are respectively installed at the ends of the drive shaft 6 and the driven shaft 7, and are detachably fixed by fasteners such as bolts. This setting can adjust the angles of the first sensing plate 8 and the second sensing plate 9 on the drive shaft 6 and the driven shaft 7. During assembly or debugging, the bolts can be loosened to adjust the first sensing plate 8 or the second sensing plate 9 respectively, and flexibly adjust the rotation angle corresponding to the door opening trigger signal or the door closing trigger signal.
[0019] Preferably, the first sensing sheet 8 and the second sensing sheet 9 are respectively provided with a first protrusion 12 and a second protrusion 13 in a lateral manner; The first protrusion 12 and the second protrusion 13 are respectively used to cooperate with the first sensor 10 and the second sensor 11 to trigger the door panel 2 opening signal and closing signal.
[0020] In this embodiment, by setting a first protrusion 12 and a second protrusion 13 on the first sensing sheet 8 and the second sensing sheet 9 respectively, and cooperating with the corresponding sensors, the triggering of the door opening and closing signals is realized. Each protrusion corresponds to a sensor, and the triggering condition is clear. Based on this, it can be accurately determined whether the door is currently in the open or closed state, avoiding misjudgment caused by ambiguous signal sources.
[0021] Furthermore, the first protrusion 12 is located on the path of the first sensing sheet 8 as it rotates with the drive shaft 6 in the door opening direction; The second protrusion 13 is located on the path of the second sensing plate 9 as it rotates along the closing direction with the driven shaft 7.
[0022] In this embodiment, the first protrusion 12 is set to correspond to the door opening rotation stroke, and the second protrusion 13 is set to correspond to the door closing rotation stroke, so that the door opening trigger signal is triggered only at the end of the stroke in the door opening direction, and the door closing trigger signal is triggered only at the end of the stroke in the door closing direction; the two protrusions act on different rotation direction strokes respectively, avoiding signal crosstalk that may occur when rotating in the same direction, and ensuring that a unique and accurate positioning signal can be obtained in both the door opening and door closing opposite motion stages.
[0023] A disinfection device that uses the aforementioned rotating door.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
