A power board fixing screw post 10 is fixedly installed at the left end of the bottom wall of the plastic shell 1. A battery is arranged inside the plastic shell 1. A display screen is snap-connected to the top of the plastic shell 1. The power cord electrically connected to the display screen passes through the door access wire outlet hole 5 and is connected to the outside. The top end of the power board fixing screw post 10 is fixedly connected to a power board. A fixing screw hole 11 is fixedly installed at the top of the left side of the plastic shell 1. A crystal head fixing lower bracket 12 is fixedly installed on the left side of the bottom wall of the plastic shell 1.

[0024] Refer to Figures 2-4 , at the top end of the crystal head fixing upper bracket 7, a connecting plate 71 is fixedly installed. At the bottom ends of the inner walls on the front and rear sides of the connecting plate 71, spring columns 72 are fixedly installed. At the top ends of the spring columns 72, a sliding plate 73 is fixedly installed. A sliding groove is provided in the inner wall of the connecting plate 71. The sliding plate 73 is slidably connected inside the sliding groove. When the elastic force of the spring column 72 pushes the sliding plate 73, the sliding plate 73 slides vertically inside the sliding groove. At the top of the end of the sliding plate 73 away from the connecting plate 71, a limiting plate 74 is rotatably connected. At the end of the limiting plate 74 away from the sliding plate 73, a plug 741 is inserted. At the top end of the sliding plate 73, a pressure spring 75 is fixedly installed. At the end of the pressure spring 75 close to the limiting plate 74, a limiting block 76 is fixedly installed. The limiting block 76 is slidably connected to the top of the sliding plate 73. The limiting block 76 and the limiting plate 74 are adapted to contact each other. The plug 741 and the two limiting plates 74 are adapted to be inserted.

[0025] Refer to Figure 2 , in the middle of the left side of the top of the connecting plate 71, a horizontal elastic telescopic rod 77 is fixedly installed. At the bottom end of the side of the horizontal elastic telescopic rod 77 away from the connecting plate 71, a vertical elastic telescopic rod 78 is fixedly installed. At the bottom end of the vertical elastic telescopic rod 78, a clamping block 79 is fixedly installed. A crystal head is arranged between the crystal head fixing upper bracket 7 and the crystal head fixing lower bracket 12. The bottom of the clamping block 79 is adapted to abut against the end face of the crystal head. The two limiting plates 74 abut against the top of the crystal head, thereby limiting the crystal head and preventing the connection from being unstable when the crystal head is pulled from the outside, thus ensuring the stability of the network.

[0026] Working principle: After the operator places the power board on the top of the power board fixing screw post 10, the power board is fixed with screws. Then, the spare battery is placed between the inner wall of the battery fixing lower bracket 2 and the plastic shell 1. At this time, the control board of the access control is placed between the RJ45 fixing upper bracket 7 and the battery fixing lower bracket 2. Then, the operator pulls up the sliding plate 73. At this time, the sliding plate 73 stretches the spring post 72 and moves upward inside the connecting plate 71. Then, the RJ45 is inserted into the corresponding network cable socket of the control board. Then, the operator releases the sliding plate 73. At this time, the sliding plate 73 will move downward under the action of the resilience of the spring post 72. At the same time, the sliding plate 73 will drive the limiting plate 74 to move downward until the limiting plate 74 abuts against the surface of the top of the RJ45. The bolt 741 is inserted into the connection part of the two limiting plates 74, so that the adjacent ends of the two limiting plates 74 are connected together. At this time, the limiting block 76 abuts against the top of the limiting plate 74 under the action of the resilience of the pressure spring 75. At this time, the limiting plate 74 is stably limited on the top of the RJ45, so as to stably limit the top of the RJ45; Then, the operator pulls the horizontal elastic telescopic rod 77 to extend and adjusts the length of the vertical elastic telescopic rod 78, so that one end of the clamping block 79 close to the RJ45 fixing upper bracket 7 abuts against the top of the end of the RJ45 connecting the data cable, so as to stably insert the RJ45 into the socket of the control board, thus avoiding the network fluctuation caused by the loosening of the RJ45.

[0027] Then, the operator passes the power cord through the power input jack 9 and connects it to the power board. Then, the power board connects the power cord to the spare battery and the control board. At this time, the machine is normally powered, and the spare battery can continue to supply power after being powered on.

[0028] After the circuit connection is completed, the operator then snaps the display screen above the plastic shell 1 and stably connects the plastic shell 1 and the display screen through the connecting barb 3 and the fixing screw hole position 11. Then, the plastic shell 1 is fixed on the wall through the screw passing through the wall hanging board screw hole position 4. At this time, the access control can be used.
