[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4 As shown, the utility model provides an access control card reader, including a shell 1 and an integrated motherboard 4, a mounting plate 2 is provided on the rear surface of the shell 1, a first connecting bolt 13 is provided through the front surface of the shell 1 near the four corners, the shell 1 and the mounting plate 2 are threadedly connected by the first connecting bolt 13, a connecting hole 21 is provided through the front surface of the mounting plate 2 near the middle, an insulating block 3 is symmetrically provided near the middle of the front surface of the mounting plate 2, one of the insulating blocks 3 is fixedly mounted on the front surface of the mounting plate 2, a plurality of copper sheets 31 are provided inside the insulating block 3, and a position near the middle of the rear surface of the integrated motherboard 4 A wiring terminal 41 is provided, and the wiring terminal 41 is fitted with the copper sheet 31. A second connecting bolt 53 is provided through the rear surface of the integrated mainboard 4 near the four corners. A mounting hole 23 is provided through the front surface of the mounting plate 2 near the four corners. The front surface of the mounting plate 2 near the top and bottom are symmetrically fixed with guide rods 22. A locking bolt 32 is symmetrically provided on the top of one of the insulating blocks 3. The two insulating blocks 3 are threadedly connected by the locking bolt 32. Guide holes 42 are provided through the front surface of the integrated mainboard 4 near the four corners, and the guide holes 42 correspond to the guide rods 22.

[0023] The effect achieved by the entire embodiment 1 is that the expansion screws are used to pass through the mounting holes 23 to install the mounting plate 2 on the building wall at the specified position, and then the cables in the wall are pulled through the connecting holes 21 to the other side of the mounting plate 2, and the metal wires of the cables are placed between the two copper sheets 31. Since the upper insulating block 3 is fixed on the mounting plate 2, by tightening the two locking bolts 32, the lower insulating block 3 moves upward, so that the cables in the wall can be fixed, and then the integrated mainboard 4 is installed on the first connecting plate 5 by the second connecting bolts 53. Since the first connecting plate 5 is fixed to the inside of the shell 1 by the spring 51 and the second connecting plate 52, the integrated mainboard 4 can be placed inside the shell 1, and then the shell 1 is installed on the surface of the mounting plate 2 by the first connecting bolts 13. At the same time, the integrated mainboard The guide hole 42 on the board 4 corresponds to the guide rod 22, and the terminal block 41 on the back of the integrated mainboard 4 fits with the copper sheet 31, so that the power supply and signal source of the wall cable can be connected to the integrated mainboard 4. Since the terminal block 41 and the copper sheet 31 adopt a contact connection, not a fixed connection, when the card reader needs to be maintained, only the first connecting bolt 13 needs to be removed to quickly remove the card reader from the mounting plate 2. By removing 53 from the back of the integrated mainboard 4, the integrated mainboard 4 can be taken out of the shell 1. The overall disassembly and assembly is convenient and fast, which is convenient for later maintenance and has broad application prospects. By setting the guide rod 22 to slide through the guide hole 42, it plays a role in guiding and limiting the integrated mainboard 4, avoiding misalignment of the terminal block 41 and the copper sheet 31, and improving the accuracy of docking.

[0024] Example 2, as Figures 1-4 As shown, a second connecting plate 52 is symmetrically fixedly connected to the inner wall of one side of the shell 1, and a spring 51 is symmetrically fixedly connected to the rear surface of the second connecting plate 52. A first connecting plate 5 is fixedly connected between the ends of the two springs 51. The first connecting plate 5 is installed on the front surface of the integrated main board 4 through a second connecting bolt 53. A notch 11 is provided on the rear surface of the shell 1, and a sealing ring 12 is provided inside the notch 11. The outer surface of one side of the sealing ring 12 is tightly fitted with the front surface of the mounting plate 2.

[0025] The effect achieved by the entire embodiment 2 is that, under the action of the elastic force of the spring 51, the first connecting plate 5 is pushed to move backward, thereby pushing the integrated main board 4 to move backward, so that the connection terminal 41 on the back of the integrated main board 4 is always tightly fitted with the copper sheet 31, which can effectively avoid the problem of poor contact. By setting the sealing ring 12, external dust can be effectively prevented from entering the interior of the shell 1, and the practicality is high.

[0026] Working principle: First, use expansion screws to pass through the mounting holes 23 to install the mounting plate 2 on the building wall at the designated position, then pull the cables in the wall through the connecting holes 21 to the other side of the mounting plate 2, and place the metal wires of the cables between the two copper sheets 31. Since the upper insulating block 3 is fixed on the mounting plate 2, by tightening the two locking bolts 32, the lower insulating block 3 moves upward, so that the cables in the wall can be fixed, and then the integrated mainboard 4 is installed on the first connecting plate 5 through the second connecting bolts 53. Since the first connecting plate 5 is fixed to the inside of the shell 1 by the spring 51 and the second connecting plate 52, the integrated mainboard 4 can be placed inside the shell 1, and then the shell 1 is installed on the surface of the mounting plate 2 through the first connecting bolt 13. At the same time, the guide holes 42 on the integrated mainboard 4 are aligned with the guide holes 42 on ... The rod 22 corresponds to the rod 22, and the terminal block 41 on the back of the integrated main board 4 fits with the copper sheet 31, so that the power supply and signal source of the wall cable can be connected to the integrated main board 4. Since the terminal block 41 and the copper sheet 31 are connected by contact, not fixedly, when the card reader needs to be maintained, only the first connecting bolt 13 needs to be removed to quickly remove the card reader from the mounting plate 2. By removing 53 from the back of the integrated main board 4, the integrated main board 4 can be taken out of the shell 1. The overall disassembly and assembly is convenient and fast, which is convenient for later maintenance and has broad application prospects. Under the action of the elastic force of the spring 51, the first connecting plate 5 is pushed backward, thereby pushing the integrated main board 4 to move backward, so that the terminal block 41 on the back of the integrated main board 4 is always tightly fitted with the copper sheet 31, which can effectively avoid the problem of poor contact.
