DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-7 As shown, an Internet of Things intelligent security door of the present invention comprises a door frame 1, a controller 11 is arranged on the upper side of the door frame 1, the controller 11 is connected to an external power supply, detection mechanisms are arranged on the inner walls on both sides of the door frame 1, a power input end of the detection mechanism is electrically connected to the power output end of the controller 11, a signal output end of the detection mechanism is signal-connected to the signal output end of the controller 11, interception mechanisms are arranged on both sides of the door frame 1, the interception mechanisms comprise a rotating shaft 13, four railings 14, an electric slip ring 15 and four temperature detection patches 16, a through groove 17 matching the rotating shaft 13 is arranged on both sides of the door frame 1, the rotating shaft 13 is rotatably assembled in the middle of the through groove 17, the electric slip ring 15 is assembled with one end of the rotating shaft 13, the four railings 14 are annularly and evenly fixedly connected to the surface of the rotating shaft 13, and the four temperature detection patches 16 are respectively fixed to the ends of the four railings 14 The door frame 1 is provided with a limit mechanism matching the rotating shaft 13, the temperature detection patch 16 and the limit mechanism are electrically connected to the controller 11 through the electric slip ring 15, and the temperature detection patch 16 is connected to the controller 11 signal through the electric slip ring 15. The present invention has a reasonable design and a clever structure. When it is detected that there is hidden metal on the person or the person's body temperature is in an abnormal state, the person can be actively intercepted, and the person can pass through the security door in an orderly manner without additionally arranging staff for guidance, thereby reducing personnel costs, and disinfectant can be applied to the surface of the railing and the temperature detection patch for disinfection to prevent the virus from spreading through the railing and the surface of the temperature detection patch. At the same time, after the disinfection is completed, the disinfectant on the surface of the railing and the temperature detection patch can be wiped to prevent the disinfectant from contacting the hands of the detection personnel and causing discomfort to the hands of the detection personnel.

[0026] Working principle: When a person enters the door frame 1, the detection mechanism detects the metal on the person's body and transmits the detection signal to the controller 111. In order to pass through the door frame 1, the person needs to hold the temperature detection patch 16 of the handrail 14 on both sides with both hands. The temperature detection patch 16 detects the palm temperature of the person and transmits the detection signal to the controller 11. If the controller 11 receives a signal that there is no hidden metal on the person and the body temperature is normal, the control limit mechanism cancels the limit on the shaft 13. At this time, the person can push the handrail 14 forward to drive the shaft 13 to rotate. When the staff pushes the handrail 14 to a suitable opening with both hands, the person can move freely. When passing between two railings 14, the hands of the person are separated from the temperature detection patch 16, and the controller 11 has no temperature signal. At this time, the limiting mechanism can be controlled to correct and limit the rotating shaft 13, and the next pair of railings 14 are facing each other and intercepted in the middle of the door frame 1; when it is detected that the person has hidden metal or abnormal body temperature, the limiting mechanism directly limits the rotating shaft 13, so that the person cannot push the railing 14, thereby intercepting and preventing the person from passing through the door frame 1. The design of four railings 14 fixed on the rotating shaft 13, when the person pushes the railing 14, the next pair of railings 14 rotates out, which can block the crowd behind, forcing the crowd to pass through the door frame 1 in an orderly manner;

[0027] The limiting mechanism includes a spring 2, a T-shaped lock 21, a first iron block 22, a first electromagnet 23 and a rotating plate 24. An inner cavity 25 matching the rotating plate 24 is provided in the door frame 1. The upper end of the rotating shaft 13 extends into the inner cavity 25 and is fixedly connected to the rotating plate 24. A step hole 26 matching the position of one of the railings 14 is provided on the lower end surface of the rotating plate 24. The T-shaped lock 21 is slidably assembled in the step hole 26. The lower end of the T-shaped lock 21 extends out of the step hole 26. Four lock holes 261 matching the positions of the four railings 14 are provided on the inner wall of the lower side of the inner cavity 25. The spring 2 is installed in the step hole 26 and is located at the upper end of the T-shaped lock 21. The first iron block 22 is installed at the upper end of the T-shaped lock 21. The first electromagnet 23 is installed at the upper end of the step hole 26. The first electromagnet 23 is electrically connected to the controller 11 through the electric slip ring 15. A guide component matching the rotating plate 24 is provided in the inner cavity 25. When a person enters the door frame 1 and detects that there is no hidden metal on the person and the body temperature is normal, the first electromagnet 23 is energized, and the first electromagnet 23 adsorbs the first iron block 22, driving the T-shaped lock 21 to retract into the upper side of the step hole 26, and the spring 2 is compressed, driving the T-shaped lock 21 to move out of the lock hole 261. At this time, the person holds the railings 14 on both sides to push the shaft 13 to rotate, so that the person passes through the door frame 1. When the person releases the temperature detection patch 16, the controller 11 does not receive the temperature information, and cancels the power supply to the first electromagnet 23. The spring 2 is stretched to push the T-shaped lock 21 out of the step hole 26. At this time, the guide component can ensure that the T-shaped lock 21 is locked into the next lock hole 261.

[0028] The guide assembly includes four second iron blocks 3 that are evenly and fixedly connected to the outer surface of the rotating plate 24 in an annular manner. The four second iron blocks 3 are respectively matched with the positions of the four lock holes 261. The inner wall of the inner cavity 25 is provided with a second electromagnet 31 that matches the second iron block 3. The second electromagnet 31 is electrically connected to the controller 11 through an electric slip ring 15. When the power supply to the first electromagnet 23 stops, the power supply to the second electromagnet 31 is supplied, and the second electromagnet 31 absorbs the second adjacent iron block 3. In order to pass through the door frame 1, the personnel will drive the rotating plate 24 to rotate through the railing 14 and the rotating shaft 13 until the personnel can pass through the door frame 1. At this time, the next second iron block 3 in the same direction of rotation of the rotating shaft 13 will be closest to the second electromagnet 31, so as to ensure that the second electromagnet 31 rotates the rotating shaft 13 in the normal direction while the next second iron block 3 in the same direction of rotation of the rotating shaft 13 is relatively absorbed with the second electromagnet 31. At this time, the T-shaped lock 21 matches the position of the next lock hole 261. The spring 2 is stretched to lock the T-shaped lock 21 into the lock hole 261, and the rotating plate 24 is limited, thereby limiting the rotating shaft 13 and the four railings 14. When the first electromagnet 23 is powered, the power supply to the second electromagnet 31 is canceled.

[0029] The left and right sides of the door frame 1 are all provided with a protective cover 4 that matches the railing 14. This ensures that the part of the railing 14 extending out of the door frame 1 is in the protective cover 4, preventing personnel from being hit by the railing 14 around the door frame 1.

[0030] A disinfection mechanism is provided on the rear side of the two protective covers 4, and the disinfection mechanism includes two first curved plates 41, two mounting frames 42, two first sponges 43, a drainage assembly and a collecting assembly. The two first curved plates 41 are arranged opposite to each other, and the two mounting frames 42 are respectively arranged on the opposite sides of the two first curved plates 41. The two mounting frames 42 are respectively detachably fixedly connected to the upper and lower sides of the protective cover 4, and the two first sponges 43 are respectively installed in the two mounting frames 42. The other ends of the two first sponges 43 abut against each other. The drainage assembly is installed on the upper surface of the upper first curved plate 41, and the drainage assembly matches the two first sponges 43. The collecting assembly is installed on the lower surface of the lower first curved plate 41, and the collecting assembly is connected to the mounting frame 42 in the lower first curved plate 41. The two first curved plates 41 are both detachably fixedly connected to the protective cover 4. The drainage component pours disinfectant into the upper mounting frame 42, which contacts the upper first sponge 43. The disinfectant passes through the first sponge 43 and enters the lower first sponge 43. At this time, both first sponges 43 contain disinfectant, and excess disinfectant flows downward into the collecting component. When a person passes through the door frame 1 and drives the four railings 14 to pass between the two first sponges 43 in turn, the railings 14 can be disinfected, and the temperature detection patch 16 can be disinfected to prevent virus transmission. Especially during an epidemic, it can effectively prevent the virus from spreading through the temperature detection patch 16 and the railing 14 to protect life safety.

[0031] The drainage assembly includes a collection tube 5, a drainage pipe 51, a connecting pipe 52 and an on-off valve 53. The collection tube 5 is mounted on the upper side of the first arc-shaped plate 41. Disinfectant is installed in the collection tube 5. The lower side of the collection tube 5 is connected to the drainage pipe 51 through the connecting pipe 52. The on-off valve 53 is assembled with the connecting pipe 52. The drainage pipe 51 is provided with a plurality of drainage ports extending into the installation frame 42. When the staff opens the on-off valve 53, the disinfectant in the collection tube 5 enters the drainage pipe 51 through the connecting pipe 52, and enters the installation frame 42 through the drainage ports to contact the first sponge 43.

[0032] The collecting assembly includes a collecting barrel 6, which is fixedly connected to the first arc-shaped plate 41 and communicated with the mounting frame 42. Excess disinfectant flows downward and enters the collecting barrel 6 for storage.

[0033] The second arc-shaped plates 61 are detachably fixedly connected to the upper and lower sides of the two protective covers 4, and the second sponge pads 62 are arranged on the opposite sides of the two second arc-shaped plates 61. After the railing 14 and the temperature detection patch 16 are disinfected, they immediately enter the two second sponge pads 62, and the second sponge pads 62 wipe the surfaces of the railing 14 and the temperature detection patch 16 to prevent the next person from holding the railing 14 and the temperature detection patch 16 and contacting the disinfectant with their hands, causing discomfort to the hands of the person.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
