The rear shell 1 has a sleeve hole 4 on its back. A guide post 5 is embedded in the mounting bracket 3, and the guide post 5 is sleeved with the sleeve hole 4. A locking nut 6 is threaded onto the guide post 5. A main control board 7 is installed in the rear shell 1. The front cover 2 is snapped onto the rear shell 1, and a sealing gasket 8 is attached between the front cover 2 and the rear shell 1. A touch screen 9 and a card reader 10 are installed in the front cover 2, and the touch screen 9 and the card reader 10 are electrically connected to the main control board 7 via double-ended ribbon cables. A lock hole is provided at the bottom inner side of the rear shell 1. 11. A rotary latch 12 is installed at the bottom of the front cover 2, and the latch of the rotary latch 12 is engaged in the lock hole 11. Through the sleeve engagement of the guide post 4 and the sleeve hole 5, combined with the locking nut 6, the rear shell 1 is quickly locked. During installation, the rear shell 1 only needs to be pre-installed on the mounting bracket 3 in the wall and the locking nut 6 is tightened to complete the fixation. The front cover 2 forms a mechanical locking and physical anti-theft mechanism with the rear shell 1 through the rotary latch 12 and the lock hole 11, which can prevent unauthorized personnel from disassembling it. During routine maintenance, the front cover 2 can be opened by simply using the rotary latch 12 to directly access the internal components without disassembling the entire device, which significantly improves the efficiency of internal component replacement.

[0019] like Figure 1 As shown, in some embodiments, the sleeve hole 4 is located at the upper and lower ends of the rear shell 1, and the guide post 5 is located at the upper and lower ends of the mounting bracket 3.

The card reader 10 is fixed to the lower part of the front cover 2. The glass cover plate 19 covers and protects the touch screen 9, forming an IP54 dustproof and waterproof protection.

[0026] During use, the rear shell 1 is quickly locked by the engagement of the guide post 4 and the sleeve hole 5, combined with the locking nut 6. During installation, the rear shell 1 only needs to be pre-installed on the mounting bracket 3 inside the wall, and the locking nut 6 can be tightened to complete the fixation. The front cover 2 forms a mechanical locking and physical anti-theft mechanism with the rear shell 1 through the rotary lock 12 and the lock hole 11, which can prevent unauthorized personnel from disassembling it. During routine maintenance, the front cover 2 can be opened by simply turning the rotary lock 12 to directly access the internal components without disassembling the entire device, which significantly improves the efficiency of internal component replacement. The upper part of the front cover 2 integrates the touch screen 9 and the glass cover 19, and the lower part is equipped with a card reader 10, forming a dual verification channel of touch and card swiping. It supports visual operation of functions such as permission setting, floor selection, and fault prompts. The main control board 7 is connected to the touch screen 9 and the card reader 10 through a double-ended ribbon cable, which simplifies the internal wiring and improves the stability of signal transmission.

[0027] In summary, the rear cover 1 is quickly locked by the sleeve engagement of the guide post 4 and the sleeve hole 5, combined with the locking nut 6. During installation, the rear cover 1 only needs to be pre-installed on the mounting bracket 3 inside the wall, and the locking nut 6 can be tightened to complete the fixation.
