Description

Technical Field

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

[0002] Access control machines are the core control devices of access control systems, enabling automated access control management. They are widely used in access control, attendance management, security alarms, parking management, elevator control, and building automation in smart buildings or smart communities.

[0003] Existing access control panels are generally exposed without protection, so when it rains, rainwater can enter the panel, causing damage and shortening its lifespan.

[0004] A search revealed a Chinese patent (CN212160783U) disclosing an access control panel. This utility model, through its protective and detachable connection to the panel body, not only allows for use according to actual conditions but also facilitates maintenance and replacement. It effectively prevents rainwater from entering the panel.

[0005] However, in actual use, when a button on the access control panel shows wear and needs to be replaced, the entire access control panel casing needs to be disassembled before the button can be replaced. This process increases maintenance time and reduces maintenance efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an access control panel to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

A second spring 9 is fixedly connected to the inner side of the outer shell 4, and a locking block 10 is fixedly connected to one end of the second spring 9. The outer side of the locking block 10 is slidably connected to the inner side of the outer shell 4, and one end of the outer shell 4 is engaged with the outer side of the limit ring 7. A pad 12 is fixedly connected to one end of the spring 5, and a rubber post 13 is fixedly connected to one end of the pad 12. The inner side of the outer shell 4 slides... A connecting post 11 is connected to the access control panel body 1. Multiple sliding blocks 14 are fixedly connected to the outside of the connecting post 11. The outside of the sliding blocks 14 is slidably connected to the inside of the mounting groove 6. A button 15 is fixedly connected to one end of the connecting post 11. A positioning mechanism is provided on one side of the access control panel body 1. The button 15 and the multiple sliding blocks 14 on one side of the connecting post 11 slide inside the mounting groove 6. The spring 15 pushes the pad 12 and the rubber post 13 to contact one end of the connecting post 11. By pressing the button 15, the connecting post 11, the pad 12 and the rubber post 13 are driven to press the circuit board inside the access control panel body 1. Then, by pushing and deflecting the limit ring 7, the multiple slots 8 inside the limit ring 7 can overlap with the multiple mounting grooves 6 inside the outer shell 4, making it easy to remove and replace the button 15, the connecting post 11 and the multiple sliding blocks 14 from the inside of the outer shell 4.

One end of the locking block 21 is fixedly connected to one end of the two telescopic rods 19, and one end of the telescopic rods 19 is fixedly connected to one side of the locking block 21. The multiple springs 20, the telescopic rods 19 and 18 push the corresponding locking blocks 21 to move inside the positioning posts 17, so that the access control panel body 1 can be quickly positioned between the access control panel body 1 and the mounting plate 2, which facilitates the subsequent fastening of the access control panel body 1 and the mounting plate 2.

[0026] The working principle of this utility model is as follows: When installing the access control panel and the mounting plate 2, multiple positioning posts 17 on one side of the access control panel body 1 are inserted into the corresponding slots 16. The telescopic rods 18, 19, and 20 on the inner side of the multiple positioning posts 17 elastically push the corresponding locking blocks 21, so that the locking blocks 21 on both sides of the positioning posts 17 can engage with the slots 16. Then, the access control panel body 1 and the mounting plate 2 are threaded together with screws. When the multiple buttons 15 on the front side of the access control panel body 1 show wear and need to be replaced, the maintenance personnel push the limit ring 7 to deflect it on the outside of the outer shell 4, so that the multiple slots 8 on the inner side of the limit ring 7 coincide with the multiple mounting slots 6 on the inner side of the outer shell 4. Then, the connecting post 11 and multiple sliding blocks 14 on the side of the button 15 can be pushed from the inside of the mounting slots 6 and slots 8 towards the outer shell. Pull out the outer side of 4, then replace button 15, connecting post 11 and sliding block 14. Then reinsert one end of button 15, connecting post 11 and multiple sliding blocks 14 into the inside of housing 4, so that one end of connecting post 11 is in contact with one side of pad 12. Then push the limiting ring 7 again, so that multiple slots 8 on the inner side of the limiting ring 7 are separated from the corresponding mounting slots 6. And make spring 2 9 and locking block 10 insert into one slot 8 on the inner side of the limiting ring 7, so that the deflection of the limiting ring 7 is limited, so that multiple sliding blocks 14 at one end of connecting post 11 can be limited inside housing 4. And push pad 12 through spring 1 5 to provide elastic support for connecting post 11, so that button 15 and connecting post 11 push pad 12 and rubber post 13, so that rubber post 13 can press the circuit board inside the access control panel body 1.
