Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective door technology, specifically to an intelligent control device for protective doors. Background Technology
[0002] The intelligent control device for protective doors is a system that integrates multiple sensors, biometric technology, network communication and automated control functions, aiming to improve the security, intelligence level and emergency response capability of protective doors.
[0003] Patent CN218780139U discloses a protective door lock device, including a smart lock body. A door handle is fixedly installed at the lower end of the front of the smart lock body. A smart control area is provided on the front of the smart lock body near the door handle. An outer cover assembly is installed on the front of the smart lock body between the door handle and the smart control area. The protective door lock device provided by this utility model includes an outer cover assembly. A driving component in the outer cover assembly adjusts the outer cover body, causing it to close and cover the smart control area, or to open and expose the smart control area for user operation. The outer cover body can automatically open and close, avoiding the inconvenience of manual closing and the possibility of forgetting to close it, thereby improving the user experience.
[0004] However, the above technology still has the following problems:
[0005] During use, fingerprints will be left on the glass keypad. Others can deduce the password combination by observing the frequency of fingerprint distribution (such as dense fingerprints of a certain number) or position (such as the first and last digits). Simple passwords (such as consecutive numbers or repeated numbers) are especially easier to crack. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an intelligent control device for protective doors.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an intelligent control device for a protective door, including a combination lock installed on the door body. The door body has an internal cavity, and a circular hole one is opened on the side of the door body near the hinge of the door frame. A circular hole two is opened on the inner wall of the cavity, penetrating the surface of the door body. A rotating mechanism is installed inside the cavity, and a traction rope one and a traction rope two are fixedly connected to the rotating mechanism. The traction rope one passes through the circular hole one and is fixedly connected to the door frame. A moving mechanism is fixedly connected to the surface of the door body, and one end of the traction rope two is fixedly connected to the moving mechanism. A circular hole three is opened on the moving mechanism, and a fixed seat is detachably connected to the circular hole three. A cleaning mechanism is detachably connected to the fixed seat.
[0008] Furthermore, the portions of the first circular hole that contact the first traction rope and the portions of the second circular hole that contact the second traction rope are both provided with rounded corners.
[0009] Furthermore, the rotating mechanism includes a rotating shaft fixedly connected to the inside of the cavity, a lever sleeved on the rotating shaft, a spring fixedly connected to the lower end of the lever, and the lower end of the spring fixedly connected to the inner wall of the cavity.
[0010] Furthermore, the moving mechanism includes two fixed blocks fixedly connected to the surface of the door, two sliding rods fixedly connected between the two fixed blocks, a slider slidably connected to the sliding rod, one end of the second traction rope fixedly connected to the upper surface of the slider, a second spring fixedly connected to the lower surface of the slider, the lower end of the second spring fixedly connected to the fixed block, and a third round hole opened on the slider.
[0011] Furthermore, the fixing seat includes a U-shaped clamping plate that matches the slider. A threaded rod is fixedly connected to the middle of the U-shaped clamping plate, and a nut is threaded onto the threaded rod. A support plate is fixedly connected to one side of the U-shaped clamping plate, and hook-and-loop fasteners are fixedly connected to the surface of the support plate.
[0012] Furthermore, the cleaning mechanism includes a velvet hook and loop fastener that matches the hook and loop fastener, with a foam pad fixedly connected to the surface of the velvet hook and loop fastener, and a cleaning cloth fixedly connected to the surface of the foam pad.
[0013] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1 to 5 A smart control device for a security door includes a combination lock 2 installed on a door body 1. The door body 1 has an internal cavity 3. A circular hole 4 is provided on the side of the door body 1 near the hinge of the door frame. A circular hole 5 penetrating the surface of the door body 1 is provided on the inner wall of the cavity 3. A rotating mechanism is installed inside the cavity 3. A traction rope 6 and a traction rope 7 are fixedly connected to the rotating mechanism. The traction rope 6 passes through the circular hole 4 and is fixedly connected to the door frame. A moving mechanism is fixedly connected to the surface of the door body 1. One end of the traction rope 7 is fixedly connected to the moving mechanism. A circular hole 8 is provided on the moving mechanism. A fixed seat is detachably connected to the circular hole 8. A cleaning mechanism is detachably connected to the fixed seat.
[0023] When the intelligent control device for the protective door of this utility model is in use, after entering the password and unlocking the combination lock 2, pulling the door body 1 causes the door body 1 to rotate. As the door body 1 rotates, the distance between the door body 1 and the hinged side of the door frame gradually increases, which allows the first traction rope 6 to apply a pulling force to the rotating mechanism. The rotating mechanism rotates, thereby transferring the pulling force to the second traction rope 7, which gradually retracts into the cavity 3. This drives the slider 13 on the moving mechanism to move upward, thereby driving the fixed seat and the cleaning mechanism installed on the fixed seat to move upward. During the movement, the cleaning mechanism can clean the fingerprints remaining on the button control panel of the combination lock 2. When the door body 1 is closed, under the action of the first spring 11 and the second spring 14, the first traction rope 6 is retracted into the cavity 3, and the fixed seat and the cleaning mechanism move downward, returning to their initial positions. In this way, the fingerprints remaining on the button control panel of the combination lock 2 can be cleaned every time the door is opened and closed.
[0024] like Figure 5 As shown, the portions of the first circular hole 4 that contact the first traction rope 6 and the portions of the second circular hole 5 that contact the second traction rope 7 are both provided with rounded corners.
[0025] Specifically, the smooth design with rounded corners reduces wear on traction rope 6 and traction rope 7, thereby extending their service life.
[0026] like Figure 5 As shown, the rotating mechanism includes a rotating shaft 9 fixedly connected inside the cavity 3, a lever 10 sleeved on the rotating shaft 9, a spring 11 fixedly connected to the lower end of the lever 10, and the lower end of the spring 11 fixedly connected to the inner wall of the cavity 3.
[0027] Specifically, when the door is opened, the first traction rope 6 applies an upward pulling force to the lever 10, causing the lever 10 to rotate around the pivot 9, thereby applying a downward pulling force to the second traction rope 7. The first spring 11 is stretched and stores energy, which causes the fixed seat and the cleaning mechanism to move on the moving mechanism. After the upper rear door 1 is closed, the first spring 11 releases energy, causing the lever 10 to return to its initial state. After the door 1 is closed, the first traction rope 6 is also in a taut state. The first traction rope 6 moves a small distance, so the force is transferred through the lever 10, and the moving distance of the second traction rope 7 is increased.
[0028] like Figure 3 As shown, the moving mechanism includes two fixed blocks fixedly connected to the surface of the door body 1, two sliding rods 12 fixedly connected between the two fixed blocks, a slider 13 slidably connected to the sliding rods 12, one end of the second traction rope 7 fixedly connected to the upper surface of the slider 13, a second spring 14 fixedly connected to the lower surface of the slider 13, the lower end of the second spring 14 fixedly connected to the fixed block, and a third round hole 8 opened on the slider 13.
[0029] Specifically, when the door 1 is opened, the second traction rope 7 applies an upward pulling force to the slider 13, the slider 13 moves upward along the slide bar 12, and the second spring 14 is stretched and stores energy. The upward movement of the slider 13 can cause the fixed seat and the cleaning mechanism on the fixed seat to move upward, thereby cleaning the fingerprints remaining on the key control panel of the combination lock 2, so as to prevent others from guessing the password combination by observing the fingerprint distribution frequency (such as a certain number of fingerprints being dense) or position (such as the first and last digits).
[0030] like Figure 4 As shown, the fixed base includes a U-shaped clamping plate 15 that matches the slider 13. A threaded rod 16 is fixedly connected to the middle of the U-shaped clamping plate 15. A nut 17 is threaded onto the threaded rod 16. A support plate 18 is fixedly connected to one side of the U-shaped clamping plate 15. A hook-and-loop fastener 19 is fixedly connected to the surface of the support plate 18.
[0031] Specifically, when installing the mounting base, insert the threaded rod 16 into the round hole 3 8 on the slider 13 until the U-shaped clamp 15 is locked onto the slider 13, and then thread the nut 17 onto the threaded rod 16. The mounting base can be removed by reversing the operation to facilitate the replacement of the cleaning mechanism.
[0032] like Figure 4 As shown, the cleaning mechanism includes a velvet hook and loop fastener 20 that matches the hook and loop fastener 19. A foam pad 21 is fixedly connected to the surface of the velvet hook and loop fastener 20, and a cleaning cloth 22 is fixedly connected to the surface of the foam pad 21.
[0033] Specifically, after removing the mounting bracket, the Velcro 20 can be peeled off from the hook Velcro 19. The cleaning cloth 22 can be cleaned and dried before reinstalling. This is to ensure the cleaning effect. As the cleaning cloth 22 moves up and down along the button control panel of the combination lock 2, the elasticity of the foam pad 21 allows the cleaning cloth 22 to adhere to the button control panel, ensuring the cleaning effect.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
