Technical Field
[0001] This utility model relates to the field of remote switching technology for magnetic doors, specifically a remote switching device for magnetic doors. Background Technology
[0002] Magnetic doors are a type of door design that uses magnetic force to achieve closure and locking. The core principle is to use a built-in magnetic attraction device (such as a magnetic strip or electromagnetic lock) to make the door leaf and the door frame adhere tightly. In hospital environments, magnetic doors are widely used in wards, operating rooms, intensive care units and other areas because of their good sealing performance, effective prevention of germs, and relatively quiet opening and closing process, which does not cause too much interference to the medical environment.
[0003] However, the magnetic doors currently used in hospitals do not have remote opening and closing capabilities. When an outsider rings the doorbell, the medical staff inside the duty room often have to walk through the corridor and reach the door, then cover the magnetic door switch with their palm so that the switch can be activated before opening the door. This repeated operation undoubtedly causes great inconvenience to the daily work of medical staff. Utility Model Content
[0004] The purpose of this utility model is to provide a remote opening and closing device for magnetic doors. This device enables remote door opening without replacing or modifying the original magnetic door switch, effectively saving operating costs and greatly facilitating the daily work of medical staff.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic door remote switch device, comprising a housing and an infrared remote controller. A micro stepper motor is fixedly installed in the middle of the left side of the inner cavity of the housing. A square rotating shaft is fixedly installed at the output end of the micro stepper motor. A fixing sleeve is fitted on the surface of the square rotating shaft. A baffle is fixedly connected to the left side of the fixing sleeve. A microcontroller is fixedly installed at the lower end of the inner cavity of the housing. An infrared receiver is fixedly installed at the upper end of the front surface of the microcontroller. A driver is fixedly installed at the lower end of the back of the microcontroller.
[0006] As a preferred embodiment, a groove is provided at the upper end of the back of the housing, and slots are provided on both sides of the outer surface of the housing. An L-shaped card plate is slidably connected to the surface of the slot, and an mounting plate is fixedly connected between the backs of the two L-shaped card plates.
[0007] As a preferred embodiment, a plastic spring is fixedly connected to the upper end of the mounting plate, and a protrusion is fixedly connected to the lower end of the plastic spring, with the surface of the protrusion slidably connected to the surface of the groove.
[0008] As a preferred embodiment, the back of the mounting plate is covered with double-sided adhesive, and the back of the double-sided adhesive is covered with a release film.
[0009] As a preferred embodiment, the bottom of the square rotating shaft is threaded with a mounting screw, the surface of which contacts the right end of the bottom of the fixing sleeve.
[0010] As a preferred embodiment, a receiving hole is provided at the lower end of the front surface of the housing, and the surface of the infrared receiver head contacts the surface of the receiving hole.
[0011] As a preferred embodiment, the bottom of the infrared remote controller is fixedly connected to a connecting ring, and a hanging rope is sleeved on the surface of the connecting ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the configuration of an infrared remote control, an infrared receiver, a microcontroller, a driver, a micro stepper motor, a square rotating shaft, a fixing sleeve, and a baffle, enables remote opening of magnetic doors by simply installing this device on one side of the magnetic door switch without requiring replacement or major modifications to the magnetic door switch. The overall use is simple and quick, greatly reducing the cost of use and providing great convenience for personnel opening doors.
[0014] 2. This utility model, through the setting of the slot and L-shaped card plate, can limit the position between the mounting plate and the shell. Through the setting of plastic spring, protrusion and groove, a certain resistance can be applied between the mounting plate and the shell, reducing the probability of the shell sliding when not operated by personnel. When personnel need to replace the battery on the back of the shell, they can push the shell upward to move it, so that the protrusion can be disengaged from the surface of the groove, and the slot can be disengaged from the surface of the L-shaped card plate, thus facilitating the disassembly of the shell for battery replacement. At the same time, the setting of double-sided adhesive makes it easy for personnel to adhere and fix the mounting plate to the wall.
[0015] 3. The present invention facilitates the installation and fixing of the fixing sleeve and the square rotating shaft by means of the installation screw, and prevents the fixing sleeve from loosening from the surface of the square rotating shaft. The setting of the receiving hole achieves the purpose of accommodating the infrared receiver head. The setting of the connecting ring and the hanging rope makes it easy for personnel to hang and place the infrared remote control. Attached Figure Description

[0023] Example 1:
[0024] Please see Figures 1-4 As shown, this utility model provides a magnetic door remote switch device, including a housing 1 and an infrared remote controller 9. A micro stepper motor 16 is fixedly installed in the middle of the left side of the inner cavity of the housing 1. A square rotating shaft 14 is fixedly installed at the output end of the micro stepper motor 16. A fixing sleeve 3 is sleeved on the surface of the square rotating shaft 14. A baffle 2 is fixedly connected to the left side of the fixing sleeve 3. A microcontroller 20 is fixedly installed at the lower end of the inner cavity of the housing 1. An infrared receiver head 8 is fixedly installed at the upper end of the front surface of the microcontroller 20. A driver 15 is fixedly installed at the lower end of the back of the microcontroller 20.
[0025] In this technical solution, by setting up an infrared remote controller 9, an infrared receiver 8, a microcontroller 20, a driver 15, a micro stepper motor 16, a square rotating shaft 14, a fixing sleeve 3, and a baffle 2, the magnetic door can be remotely opened by adding this device to one side of the magnetic door switch without replacing or making major modifications to the magnetic door switch. The overall use is simple and quick, greatly reducing the cost of use, and bringing great convenience to the personnel opening the door.
[0026] Example 2:
[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a groove 17 is provided at the upper end of the back of the housing 1, and slots 7 are provided on both sides of the outer surface of the housing 1. An L-shaped card plate 5 is slidably connected to the surface of the slot 7. An mounting plate 6 is fixedly connected between the backs of the two L-shaped card plates 5. A plastic spring piece 12 is fixedly connected to the upper end of the mounting plate 6. A protrusion 18 is fixedly connected to the lower end of the plastic spring piece 12. The surface of the protrusion 18 is slidably connected to the surface of the groove 17. A double-sided adhesive 13 is pasted on the back of the mounting plate 6, and a release film is pasted on the back of the double-sided adhesive 13.
[0028] In this technical solution, the slot 7 and the L-shaped plate 5 limit the movement between the mounting plate 6 and the housing 1. The plastic spring 12, the protrusion 18 and the groove 17 apply resistance between the mounting plate 6 and the housing 1, reducing the chance of the housing 1 sliding when not in use. When personnel need to replace the battery on the back of the housing 1, they can push the housing 1 upward to move it, causing the protrusion 18 to disengage from the surface of the groove 17, until the slot 7 is released from the surface of the L-shaped plate 5. This facilitates the disassembly of the housing 1 to replace the battery. The double-sided adhesive 13 facilitates the adhesion and fixation of the mounting plate 6 to the wall.
[0029] Example 3:
[0030] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, a mounting screw 4 is threadedly connected to the bottom of a square rotating shaft 14. The surface of the mounting screw 4 contacts the right end of the bottom of the fixing sleeve 3. A receiving hole 19 is provided at the lower end of the front surface of the housing 1. The surface of the infrared receiver head 8 contacts the surface of the receiving hole 19. A connecting ring 10 is fixedly connected to the bottom of the infrared remote controller 9. A hanging rope 11 is sleeved on the surface of the connecting ring 10.
[0031] In this technical solution, the installation screw 4 facilitates the installation and fixation of the fixing sleeve 3 and the square rotating shaft 14, preventing the fixing sleeve 3 from loosening from the surface of the square rotating shaft 14. The receiving hole 19 accommodates the infrared receiver head 8. The connecting ring 10 and the hanging rope 11 facilitate the hanging and placement of the infrared remote control 9.
[0032] The working principle of this utility model is as follows: This device is installed on one side of the magnetic door switch, and the baffle 2 is positioned above the sensing area of the magnetic door switch in a horizontal state. When an outsider presses the doorbell, the medical staff at the door of the duty room can press the button on the infrared remote control 9 to emit an infrared signal. After being received by the infrared receiver 8, the infrared signal is analyzed by the microcontroller 20 and can send a command to the driver 15. The driver 15 can then control the micro stepper motor 16 to rotate 360 degrees according to the command. Under the action of the micro stepper motor 16, the square rotating shaft 14, the fixed sleeve 3, and the baffle 2 can rotate. As the baffle 2 rotates and gradually becomes vertical, it can block the sensing area of the magnetic door switch, and the magnetic door switch can operate the magnetic door to open under the state of being blocked, thereby realizing the function of remotely opening the magnetic door.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
