[0001] This utility model relates to a multi-functional access control device, and in particular to a multi-functional access control device, belonging to the technical field of access control devices. Background Technology

[0002] Access control and security management systems are a new type of modern security management system. They integrate microcomputer automatic identification technology and modern security management measures. They involve many new technologies such as electronics, mechanics, optics, computer technology, communication technology, and biotechnology. They are an effective measure to solve the security management of important department entrances and exits and are suitable for various confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories, etc.

[0003] Currently, most common access control revolving door systems on the market use a mechanical structure where a motor drives a rotating rod. The rotating rod is fixedly connected to the revolving door, and the door opens and closes by rotating the rod driven by the motor. While this design can meet daily passage needs, it has significant safety hazards: when the motor fails, because the rotating rod and the revolving door are rigidly connected, the entire revolving door system will completely lose power, causing the door to be unable to rotate and severely hindering normal passage. Especially in emergencies, this design flaw may cause safety hazards and affect the efficiency of personnel evacuation.

[0004] Therefore, there is an urgent need to improve a multi-functional access control device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional access control device that allows staff to manually rotate the revolving door when the motor cannot drive it, thus preventing people from being unable to enter or exit freely.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a multi-functional access control device, comprising a frame, a rotating door connected to one end of the frame via a rotating rod, a driving device fixedly installed at one end of the rotating rod, a turntable fixedly installed at the lower end of the driving device, and a base rotatably connected to the turntable.

[0007] Preferably, the frame is rotatably connected to the rotating rod, and the rotating rod is fixedly connected to the revolving door.

[0008] Preferably, the rotating rod extends into the interior of the frame, and the driving device is located inside the frame.

[0009] Preferably, the base has an annular groove, which is rotatably connected to the turntable and is used to limit the rotation of the turntable.

[0010] Preferably, a handle is fixedly installed on one side of the turntable, the handle extends to the outside of the base, and a limiting groove is formed on the turntable.

[0011] Preferably, a hole is provided on one side of the annular groove, a spring is fixedly installed at one end of the hole, and a limit block is fixedly installed at the end of the spring away from the hole.

[0012] Preferably, a telescopic rod is fixedly installed at one end of the limiting block, and the end of the telescopic rod away from the limiting block is fixedly connected to one end of the hole.

[0013] Preferably, the spring is sleeved and connected to the telescopic rod, and the limiting block is slidably connected to the limiting groove.

[0014] Preferably, a cover plate is connected to one side of the frame by bolt thread.

[0015] Preferably, the frame is provided with a card swiping area, and a facial recognition machine is fixedly installed on the frame.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. When the staff activates the drive device, it can drive the rotating rod to rotate, thereby causing the revolving door fixedly connected to the rotating rod to rotate and open, allowing people to enter and exit freely. When the drive device malfunctions, the staff can manually rotate the turntable, causing the turntable to rotate, which in turn drives the drive device fixedly connected to it to rotate, thereby causing the rotating rod to rotate, and then the revolving door fixedly connected to the rotating rod to rotate and open, thus avoiding the impact on personnel entry and exit when the drive device malfunctions.

[0018] 2. When the rotating rod rotates 90°, the revolving door will rotate to open or close. Thus, when the staff pulls the handle to rotate the turntable, the limit block is always in contact with the upper surface of the turntable. When the limit groove on the turntable rotates to the limit block, the turntable rotates exactly 90°. At the same time, the limit block will be engaged into the limit groove by the elastic force of the spring. At this time, the revolving door rotates exactly 90°, allowing people to enter and exit freely. Attached Figure Description

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Examples, such as Figures 1-4 As shown, a multi-functional access control device includes a frame 1. One end of the frame 1 is connected to a revolving door 5 via a rotating rod 4. A drive device 9 is fixedly installed at one end of the rotating rod 4. A turntable 10 is fixedly installed at the lower end of the drive device 9. The turntable 10 is rotatably connected to a base 11. By setting the output end of the drive device 9 to be fixedly connected to one end of the rotating rod 4, when the staff activates the drive device 9, it can drive the rotating rod 4 to rotate, thereby causing the revolving door 5 fixedly connected to the rotating rod 4 to rotate and open, allowing personnel to enter and exit freely. When the drive device 9 malfunctions or the power system has a problem, the staff can manually rotate the turntable 10. When the turntable 10 rotates, it can drive the drive device 9 fixedly connected to it to rotate as a whole, thereby causing the rotating rod 4 to rotate, and then the revolving door 5 fixedly connected to the rotating rod 4 can rotate and open, avoiding the impact on personnel entry and exit when the drive device 9 malfunctions.

[0027] like Figures 1-4As shown, the frame 1 is rotatably connected to the rotating rod 4, and the rotating rod 4 is fixedly connected to the revolving door 5. The rotating rod 4 extends into the interior of the frame 1, and the driving device 9 is located inside the frame 1. By setting the frame 1 and the rotating rod 4 to be rotatably connected, and the rotating rod 4 extending into the interior of the frame 1, the rotating rod 4 can remain stable when rotating. Thus, the rotating rod 4 drives the revolving door 5, which is fixedly installed with it, to rotate. In turn, the revolving door 5 will also remain stable during the rotation. By setting the driving device 9 inside the frame 1, the driving device 9 is protected from damage by external forces.

[0028] like Figures 3-4 As shown, further, an annular groove 12 is provided on the base 11, and the annular groove 12 is rotatably connected to the turntable 10. The annular groove 12 is used for rotational limiting of the turntable 10. A handle 14 is fixedly installed on one side of the turntable 10, and the handle 14 extends to the outside of the base 11. A limiting groove 13 is provided on the turntable 10. By providing an annular groove 12 on the base 11 and rotatably connecting the annular groove 12 to the turntable 10, the turntable 10 can rotate stably within the annular groove 12 when the operator manually rotates the turntable 10, thus allowing the operator to rotate the turntable 10 with less effort. By fixing the handle 14 on the turntable 10, the operator can drive the turntable 10 to rotate when rotating the handle 14, making it easier for the operator to operate the turntable 10. By setting the handle 14 to extend to the outside of the base 11 and located inside the frame 1, it is convenient for the operator to use the handle 14.

[0029] like Figures 3-4 As shown, further, a hole 16 is provided on one side of the annular groove 12. A spring 17 is fixedly installed at one end of the hole 16, and a limit block 15 is fixedly installed at the end of the spring 17 away from the hole 16. A telescopic rod 171 is fixedly installed at one end of the limit block 15. The end of the telescopic rod 171 away from the limit block 15 is fixedly connected to one end of the hole 16. The spring 17 and the telescopic rod 171 are sleeved together. The limit block 15 is slidably connected to the limit groove 13. When the rotating rod 4 rotates 90°, the revolving door 5 will rotate open or close. Thus, when the operator pulls the handle 14 to rotate the turntable 10, the limit block 15 is always in contact with the upper surface of the turntable 10. When the limiting groove 13 on the turntable 10 rotates to the limiting block 15, the turntable 10 rotates exactly 90°. At the same time, the limiting block 15 will be engaged into the limiting groove 13 by the elastic force of the spring 17. At this time, the revolving door 5 rotates exactly 90°, allowing people to enter and exit freely. By setting the telescopic rod 171 and connecting it with the spring 17, the limiting block 15 can remain stable and not shake when it moves. At the same time, the bottom surface of the limiting block 15 is arc-shaped. When the staff rotates the turntable 10 again, the limiting block 15 will slide out from the limiting groove 13 for easy reuse. Meanwhile, the base 11 limits the rotation range of the handle 14 to prevent the turntable 10 from rotating excessively.

[0030] like Figures 1-2 As shown, a cover plate 2 is further connected to one side of the frame 1 by bolts 3. A card swiping area 7 is provided on the frame 1, and a facial recognition machine 6 is fixedly installed on the frame 1. By setting up the card swiping area 7 and the facial recognition machine 6, people can have multiple ways to enter and exit. At the same time, the card swiping area 7 and the facial recognition machine 6 are existing technologies and will not be described in detail here.

[0031] In this embodiment, as Figures 1-4 As shown, the principle of a multi-functional access control device provided in this embodiment is as follows:

[0032] When the operator activates the drive device 9, it rotates the rotating rod 4, which in turn rotates the revolving door 5, which is fixedly connected to the rotating rod 4, allowing personnel to enter and exit freely. If the drive device 9 malfunctions, the operator can manually pull the handle 14, which rotates the turntable 10, causing the drive device 9, which is fixedly connected to the turntable 10, to rotate. This, in turn, rotates the rotating rod 4, allowing the revolving door 5, which is fixedly connected to the rotating rod 4, to rotate and open, preventing malfunctions when the drive device 9 malfunctions. In case of malfunction, it will affect the entry and exit of personnel. At the same time, when the rotating rod 4 rotates 90°, the revolving door 5 will rotate to open or close. Thus, when the staff pulls the handle 14 to drive the turntable 10 to rotate, the limit block 15 will always be in contact with the upper surface of the turntable 10. When the limit groove 13 on the turntable 10 rotates to the limit block 15, the turntable 10 will rotate exactly to 90°. At the same time, the limit block 15 will be locked into the limit groove 13 by the elastic force of the spring 17. At this time, the revolving door 5 will rotate exactly 90°, allowing personnel to enter and exit freely.
