Description

Technical Field

[0001] This utility model relates to the field of access control and monitoring technology, specifically to an access control and monitoring device. Background Technology

[0002] Access control and monitoring devices are comprehensive equipment systems used to control personnel access permissions, ensure the security of specific areas, and monitor relevant status in real time.

[0003] According to CN219872456U, an access control monitoring device includes a fixed plate with a fingerprint collection area on its top. A first movable plate and a second movable plate are respectively located on either side of the top of the fingerprint collection area. This invention uses a wiping cloth to cover the top surface of the fingerprint collection area in its initial state, effectively preventing dust from settling on it and achieving dustproof treatment. When an infrared sensor detects an approaching heat source, the fingerprint collection area automatically exposes for use. When the heat source leaves, the first and second movable plates return to their initial positions, and the wiping cloth covers the top surface of the fingerprint collection area. The movement of the first and second movable plates allows for wiping the top surface of the fingerprint collection area with the wiping cloth, effectively preventing debris from affecting fingerprint recognition and ensuring the effectiveness of the fingerprint collection area.

[0004] The aforementioned wiping cloth and other structures can clean the fingerprint collection area. However, after the wiping cloth has finished wiping the fingerprint collection area, foreign objects and dust will adhere to the wiping cloth. When used again, foreign objects or dust are easy to adhere to the fingerprint collection area again, causing secondary pollution and affecting the use effect. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 6 As shown, in this embodiment, an access control monitoring device includes a housing 1. A guide groove 2 is provided on one side of the front of the housing 1. A rack plate 3 is slidably connected inside the guide groove 2. A connecting plate 4 is fixedly connected to the side of the rack plate 3 away from the housing 1. An L-shaped mounting bracket 5 is fixedly connected to the side of the connecting plate 4 away from the rack plate 3 by screws.

A toothed belt 11 meshes with the surfaces of the drive gear 10 and the transmission gear 9. A cleaning cloth 12 is provided on the surfaces of the feeding roller 7 and the winding roller 8. One end of the rotating shaft of the feeding roller 7 is fixedly connected to the output end of the motor 6.

[0025] The mounting bracket 5 is fixed to the connecting plate 4 with screws. The mounting bracket 5 and the cleaning cloth 12 are used to protect and wipe the fingerprint collection panel 21, reducing dust adhesion to its surface and removing foreign objects or traces left during collection. After wiping, the motor 6 is started. Its output shaft drives the drive gear 10 and the unloading roller 7 to rotate. The power is transmitted to the transmission gear 9 through the toothed belt 11, which drives the winding roller 8 to rotate. The unloading roller 7 releases the clean cleaning cloth 12, and the winding roller 8 winds up the dirty cleaning cloth 12 to replace the cleaning cloth 12 and avoid secondary pollution of the fingerprint collection panel 21.

[0026] A connecting box 13 is fixedly connected to one side of the equipment housing 1. Multiple heat dissipation holes 14 are opened on the side of the connecting box 13 away from the mounting frame 5. A motor 15 is fixedly connected to the bottom of the inner wall of the connecting box 13. A rotating gear 16 is fixedly sleeved on the output shaft of the motor 15. The rotating gear 16 meshes with the rack plate 3.

[0027] When the motor 15 is started, its output shaft drives the rotating gear 16 to rotate. Since the rack plate 3 and the rotating gear 16 mesh, the rack plate 3 drives the connecting plate 4 and the mounting bracket 5 to move to one side, thereby realizing the exposure and cover of the fingerprint collection panel 21.

[0028] A display screen 17 and a control panel 18 are provided on one side of the front of the device housing 1, with the control panel 18 located at the bottom of the display screen 17.

[0029] On the side of the device housing 1 away from the display screen 17, a camera 19, a sound hole 20 and a fingerprint collection panel 21 are arranged vertically in sequence. The fingerprint collection panel 21 is in contact with the cleaning cloth 12.

[0030] By setting a camera 19 and a fingerprint collection panel 21 on one side of the device housing 1, the device can collect images and fingerprints, thereby monitoring the surrounding environment and recording user information to ensure security.

[0031] A back plate 22 is fixedly connected to the back of the equipment housing 1. Multiple heat dissipation holes 23 are opened inside the back plate 22. Fixing plates 24 are fixedly connected to the four corners of the back plate 22. The fixing plates 24 are L-shaped.

[0032] A connecting frame 26 is fixedly connected to the side of the back plate 22 away from the equipment housing 1. A slot 27 is provided at the bottom of the connecting frame 26. A dustproof net 28 is slidably connected inside the slot 27. A limiting plate 29 is fixedly connected to the bottom of the dustproof net 28. The top of the limiting plate 29 is in contact with the connecting frame 26.

[0033] Rotating plates 25 are symmetrically arranged on both sides of the bottom of the equipment housing 1, and the bottom of the rotating plates 25 and the limiting plate 29 abut against each other.

[0034] By setting L-shaped fixing plates 24 at the four corners of the back plate 22, a certain space can be maintained between the equipment housing 1 and the installation position after installation to ensure normal air circulation. Multiple heat dissipation holes 23 are provided on the back plate 22, which can dissipate the heat generated by the device to the outside with the air flow to improve the heat dissipation effect of the device. A dustproof net 28 is provided on the side of the heat dissipation hole 14 to reduce the entry of foreign objects or particles into the equipment housing 1. After the device has been used for a period of time, the rotating plate 25 is rotated and separated from the limiting plate 29. The dustproof net 28 can be removed and cleaned by pulling down the limiting plate 29, thereby ensuring the ventilation effect of the heat dissipation hole 23.

[0035] This utility model provides an access control and monitoring device, the specific working principle of which is as follows:

[0036] In use, the device housing 1 is fixed to the workplace by the fixing plate 24. The dustproof net 28 is inserted into the connecting frame 26 through the slot 27. The rotating plate 25 is rotated and abuts against the limiting plate 29, thereby fixing the position of the dustproof net 28. When the device is working, the heat generated can be discharged through the heat dissipation hole 23, and the dustproof net 28 reduces the entry of foreign objects. A camera 19 and a fingerprint collection panel 21 are set on one side of the device housing 1, which can collect human images and fingerprints to monitor the surrounding environment and realize the input of user information to ensure the security of use. When the fingerprint collection panel 21 needs to collect fingerprints, the control panel 18 controls the motor 15 to work and rotate the gear. When the rack plate 3 and the rotating gear 16 rotate, the rack plate 3 drives the connecting plate 4 and the mounting bracket 5 to move to one side, and the fingerprint collection panel 21 is exposed. After the collection is completed, the rotating gear 16 rotates back, and the rack plate 3 drives the cleaning cloth 12 back to its original position. During the movement, the cleaning cloth 12 wipes the fingerprint collection panel 21 to ensure the surface is clean. At the same time, the motor 6 works, and its output shaft drives the drive gear 10 and the feeding roller 7 to rotate. The power is transmitted to the transmission gear 9 through the toothed belt 11, so that the transmission gear 9 drives the take-up roller 8 to rotate. Thus, the feeding roller 7 releases the clean cleaning cloth 12, and the take-up roller 8 takes up the dirty cleaning cloth 12 to realize the replacement of the cleaning cloth 12.
