[0036] The present utility model provides an access control device by improvement. The technical solution of the present utility model is:

[0037] As Figure 1 shown,

[0038] An access control device includes a housing 1 and a connecting plate 2.

[0039] A locking mechanism 3 is provided at the bottom of the back surface of the housing 1. The locking mechanism 3 can extend or retract into the housing 1, and the locking mechanism 3 is used to lock the connecting plate 2.

[0040] As Figure 2As shown, the connecting plate 2 is embedded in the housing 1. The connecting plate 2 is located above the locking mechanism 3, and the back surface of the connecting plate 2 is in the same plane as the back surface of the housing 1. After the housing 1 and the connecting plate 2 are installed, the connecting plate 2 is fixed on the door body. The periphery of the housing 1 wraps the connecting plate 2. The back surfaces of the connecting plate 2 and the housing 1 are both in close contact with the surface of the door body, and dust is not likely to enter the housing 1. Dust is not likely to accumulate on the device to hinder heat dissipation, and it will not cause the device to overheat, etc., and the communication quality is high.

[0041] A connecting member is connected to the housing 1. A connection hole 21 is provided in the connecting plate 2 near the connecting member. The connecting member is located in the connection hole 21. The connection hole 21 includes a first connection portion 211 and a second connection portion 212 that communicate with each other. The connection portion is located above the second connection portion 212. The diameter of the first connection portion 211 is greater than the diameter of the connecting member, and the diameter of the second connection portion 212 is smaller than the diameter of the largest part of the connecting member. In some embodiments, the connecting member is a screw, and the diameter of the head of the screw is smaller than the diameter of the first connection portion 211 and greater than the diameter of the second connection portion 212.

[0042] As Figure 4 As shown, a first adjustment hole is provided in the bottom surface of the housing 1, and a second adjustment hole is provided in the back surface of the housing 1 near the locking mechanism 3. The locking mechanism 3 includes an adjustment column 31 and a detent 32. The side wall of the adjustment column 31 abuts against the detent 32. The top end of the adjustment column 31 is conical. The adjustment column 31 is located in the first adjustment hole, and the adjustment column 31 is threadedly connected to the first adjustment hole. The detent 32 is located in the second adjustment hole, and the diameter of the detent 32 is greater than the diameter of the second adjustment hole.

[0043] When it is not necessary to disassemble the housing 1 and the connecting plate 2, adjust the locking mechanism 3 so that the detent 32 extends out of the housing 1. The detent 32 interferes with the connecting plate 2, and the connecting plate 2 cannot move downward. At this time, the connecting member is located in the second connecting portion 212, and the diameter of the second connecting portion 212 is smaller than the maximum diameter of the connecting member. Therefore, the connecting member cannot be disengaged from the second connecting portion 212, and the connecting plate 2 and the housing 1 are connected together. When it is necessary to disassemble the housing 1 and the connecting plate 2, when adjusting the locking mechanism 3, rotate the adjusting column 31 so that the adjusting column 31 moves downward. The conical head of the adjusting column 31 abuts against the detent 32, and the detent 32 retracts into the housing 1. At this time, the connecting plate 2 can move downward, and the connecting member moves into the second connecting portion 212. The diameter of the second connecting portion 212 is larger than the diameter of the connecting member. Therefore, the connecting plate 2 can be disengaged from the second connecting portion 212. Thus, the separation of the housing 1 and the connecting plate 2 can be completed.

[0044] In use, the connecting plate 2 is fixedly arranged on the door body. In some embodiments, the connecting plate 2 can be fixedly connected to the door body by glue, and can also be fixed on the door body by connection means such as screws. The specific connection method is not limited in this embodiment. The housing 1 is detachably connected to the connecting plate 2 through the connecting member, and the installation and disassembly processes are more convenient, without the need for complex tools or professional skills, reducing the operation difficulty. In some embodiments, a wireless communication module can also be arranged in the housing 1, and wireless connection and communication are carried out with the outdoor unit through the wireless communication module. The access control device described in this embodiment can be fixed on the door body or detached from the door body, and can be quickly deployed at any required position according to actual needs. When the requirements change, the position can also be quickly adjusted, greatly improving the flexibility of the access control device. The user can place the access control device at the required position and can quickly perform operations such as unlocking or communicating with visitors.

[0045] As Figure 3 shown, a back plate 14, a circuit board 15, and a display screen 16 are fixedly arranged in the housing 1 in sequence from back to front.
