[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0025] See also Figures 1 to 5 In the utility model, a medical radiation-proof electric induction door comprises a loading plate 1 and two radiation-proof door plates 2. The two radiation-proof door plates 2 are both located on the back of the loading plate 1 and are slidably connected to the loading plate 1. A bidirectional infrared sensor 3 is fixedly installed on the front of the loading plate 1. A guide seat 4 is fixedly connected to the back of the loading plate 1. The tops of the two radiation-proof door plates 2 are fixedly connected to synchronous seats 5. The tops of the synchronous seats 5 penetrate and extend to the tops of the guide seats 4. The synchronous seats 5 are slidably connected to the inner walls of the guide seats 4. A servo motor 6 is fixedly installed on the back of the loading plate 1. A screw rod is fixedly connected to the output shaft of the servo motor 6. Two moving seats 7 are threadedly connected to the screw rod. The moving seat 7 slides with the loading plate 1. Dynamic connection, the interior of the synchronous seat 5 is provided with a mounting groove 8, the movable seat 7 is located inside the mounting groove 8, an electromagnetic seat 9 is installed on the inner bottom wall of the mounting groove 8, the top of the electromagnetic seat 9 is magnetically connected to a magnetic plate 10, the top of the magnetic plate 10 is fixedly connected to a fitting seat 11, the bottom of the movable seat 7 is provided with a fitting groove 12, the top of the fitting seat 11 passes through the mounting groove 8 and extends to the inside of the fitting groove 12, the interior of the loading plate 1 is installed with a processor 13, a remote sensing module 14 and a variable resistor 15, the variable resistor 15, the servo motor 6, the bidirectional infrared sensor 3, the remote sensing module 14 and the electromagnetic seat 9 are all connected to the processor 13 signal, and the variable resistor 15 is connected to the bidirectional infrared sensor 3.

[0026] When in use, the two-way infrared sensor 3 is used to sense the people inside and outside. When it is detected that a person is walking and approaching, the two-way infrared sensor 3 is triggered to transmit the signal to the processor 13. The processor 13 controls the servo motor 6 to be powered on. After the servo motor 6 is powered on, it drives the screw rod fixed to it to rotate synchronously, and the moving seat 7 threaded on the screw rod begins to move in the opposite direction. At this time, the electromagnetic seat 9 is in the energized state to generate the same magnetic field as the top magnetic plate 10, so that the fitting seat 11 is in the fitting groove 12 so that the synchronous seat 5 and the moving seat 7 form a whole. Under the push of the moving seat 7, the synchronous seat 5 moves accordingly and pulls the radiation-proof door panel 2 to move, thereby realizing automatic opening. When the person leaves, the two-way infrared sensor 3 transmits a signal to the processor 13, and the servo motor 6 The anti-radiation door panel 2 is closed by rotating in the opposite direction. In actual use, medical staff can control the resistance of the variable resistor 15 through the remote sensing module 14. The variable resistor 15 is installed in the circuit of the two-way infrared sensor 3, so as to adjust the sensitivity of the two-way infrared sensor 3. In some scenarios, personnel are required to stand at the bottom of the two-way infrared sensor 3 for a certain period of time before the anti-radiation door panel 2 will open and close. If an unexpected situation occurs in the use scenario, causing the entire equipment to be powered off or the two-way infrared sensor 3 fails, the self-locking anti-radiation door panel 2 of the driving equipment is difficult to open. At this time, the powered-off electromagnetic seat 9 loses its magnetic field, and the fitting seat 11 under the action of gravity falls off from the fitting groove 12 into the installation groove 8. At this time, the moving seat 7 is separated from the synchronous seat 5, and personnel can push the anti-radiation door panel 2 to open.

[0027] In this embodiment, a bidirectional infrared sensor 3 is provided in cooperation with a servo motor 6 to realize the opening and closing of the radiation protection door panel 2. The control is simple and effective, and no manual operation is required, thereby improving adaptability. At the same time, the sensitivity of the bidirectional infrared sensor 3 can be adjusted by providing a variable resistor 15, thereby ensuring that the radiation protection door panel 2 responds more accurately and reliably to the human body, specific objects or other interference sources, which helps to reduce false triggering and avoid accidents, thereby improving the safety of patients and medical staff.

[0028] Infrared sensitivity adjustment can make the sensor door more intelligent. It can be adjusted according to different scenarios and needs, so as to better adapt to the usage of different areas in the hospital. The sensitivity can be increased in areas that require more frequent entry and exit, while the sensitivity can be lowered in some specific areas to ensure smooth entry and exit and meet the needs of medical staff and patients.

[0029] And through the coordinated use of the electromagnetic seat 9 and the magnetic plate 10, a restrictive effect can be exerted on the fitting seat 11. Under normal operation, the synchronous seat 5 and the movable seat 7 form a whole to realize the opening and closing of the radiation-proof door panel 2. When the two-way infrared sensor 3 is damaged or a fire occurs, causing the entire induction door to lose power, the fitting seat 11 falls off from the fitting groove 12 due to gravity, so that the synchronous seat 5 is separated from the movable seat 7. The medical staff can manually open the radiation-proof door panel 2 to avoid the self-locking of the driving device causing the induction door to be unable to be opened, thereby ensuring the safety of medical staff and patients.

[0030] See also Figure 5 , wherein: a flashing light 16 is installed on the loading plate 1 , and the flashing light 16 is connected to the processor 13 by signal.

[0031] In this embodiment, when the radiation protection door panel 2 is opened and closed, the processor 13 will simultaneously control the flashing light 16 to flash. The flashing light 16 can serve as a reminder to medical staff and patients so that they can understand the status of the sensor door.

[0032] See also Figure 2 and 3 , wherein: a guide groove 17 is opened on the back of the loading plate 1, and the moving seat 7 is slidably connected to the inner wall of the guide groove 17.

[0033] In this embodiment, the setting of the guide groove 17 can limit the movable seat 7, so that the movable seat 7 can always be located at the back of the loading plate 1 to maintain stable movement in the horizontal direction.

[0034] See also Figure 4 , wherein: a damping pad 18 is fixedly connected to the inner wall of the fitting groove 12, and the damping pad 18 is made of rubber material.

[0035] In this embodiment, when the mating seat 11 moves upward and enters the mating groove 12, it will contact the damping pad 18 made of rubber material. The damping pad 18 will deform to prevent the mating seat 11 from shaking, and at the same time can play a certain buffering role. When the moving seat 7 moves, the mating seat 11 is subjected to force to prevent the mating seat 11 from causing excessive pressure on the inner wall of the mating groove 12 and causing deformation.

[0036] See also Figure 1 , wherein: an adjusting knob 19 is fixedly mounted on the front of the loading plate 1 , and the adjusting knob 19 is connected to the variable resistor 15 .

[0037] In this embodiment, in actual use, medical staff can directly turn the adjustment knob 19 to change the resistance of the variable resistor 15 , thereby changing the sensitivity of the bidirectional infrared sensor 3 .

[0038] See also Figure 1 and 2, wherein: the front and back sides of the radiation-proof door panel 2 are fixedly connected with a handle 20 , and the handle 20 is provided with evenly distributed anti-slip grooves.

[0039] In this embodiment, when medical staff need to manually open the radiation protection door panel 2, the handle 20 can provide a good fulcrum for them, and the anti-slip pattern can prevent the user from slipping.

[0040] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and its improved conception of the utility model, which should be included in the protection scope of the utility model.
