[0026] Reference Figure 3-Figure 5A waterproof structure of an attendance access control machine comprises a front cover 1, a fingerprint head 2 is arranged at the bottom of the front end of the front cover 1, a rear cover 3 is clamped at the rear end of the front cover 1, a shielding component 4 is arranged at the top of the rear cover 3, a main board 5 is arranged inside the front cover 1, a buckle 6 is fixedly installed on the bottom wall of the rear cover 3, the main board 5 is clamped between the front cover 1 and the rear cover 3, a card slot adapted to be clamped with the buckle 6 is provided on the inner wall of the front cover 1, so that the connection between the front cover 1 and the rear cover 3 through the clamping of the buckle 6 and the card slot is more firmly established, a waterproof step 7 is fixedly installed at the center of the bottom wall of the rear cover 3, a waterproof speaker 8 is fixedly installed on the left side of the bottom end of the rear cover 3, a power charging port 9 is provided on the right side of the bottom end of the rear cover 3, a waterproof rubber plug 10 is clamped inside the power charging port 9, the power charging port 9 runs through the bottom end of the rear cover 3, the outer wall of the waterproof rubber plug 10 is fitted with the inner wall of the power charging port 9, and the waterproof rubber plug 10 can be used for power charging. The power charging port 9 is blocked to prevent water drops from penetrating from the power charging port 9 to the interior of the back cover 3 when the power charging port 9 is not in use. A groove 11 is provided at the edge of the proximal end of the front cover 1 and the back cover 3. A waterproof rubber ring 12 is provided inside the groove 11. The grooves 11 respectively provided on the front cover 1 and the back cover 3 are connected. The waterproof rubber ring 12 is connected to the inside of the two grooves 11 by a 3mm thick double-sided tape. The waterproof rubber ring 12 can seal the connection between the front cover 1 and the back cover 3 to prevent water vapor from penetrating from the connection between the front cover 1 and the back cover 3 to the interior of the front cover 1 and the back cover 3. A screw hole 13 is fixedly installed on the inner wall of the front cover 1, and a screw hole matched with the screw hole 13 is provided on the surface of the back cover 3. Screws are connected to the internal threads of the screw hole 13 and the screw hole. The front cover 1 and the back cover 3 are firmly connected by screws, and a cover plate 14 is fixedly installed at the rear end of the back cover 3.

[0027] Reference Figure 1-Figure 2 The shielding assembly 4 includes two hexagonal sleeves 41 that are clamped on the front and rear sides of the rear cover 3. A vertical rod 42 is fixedly installed on the top of the hexagonal sleeve 41. An elastic rod 43 is fixedly installed on one end of the vertical rod 42 near the middle of the front cover 1. An external connecting sleeve 44 is slidably connected to the surface of the elastic rod 43. A shielding plate 45 is slidably connected to the surface of the external connecting sleeve 44. A hexagonal block that is adapted to be clamped and engaged with the hexagonal sleeve 41 is fixedly installed on the front and rear ends of the rear cover 3. There are two vertical rods 42 and they are symmetrically arranged on the tops of the two hexagonal sleeves 41. The front and rear ends of the elastic rod 43 are fixedly connected to the two vertical rods 42 respectively. After the hexagonal sleeve 41 is installed on the surface of the rear cover 3, the vertical rod 42 can support the shielding plate 45 above. A rectangular groove that is adapted to be slidably connected with the elastic rod 43 is opened inside the shielding plate 45. The shielding plate 45 is located above the front cover 1 and the rear cover 3. The shielding plate 45 can block the top of the front cover 1 and the rear cover 3, thereby achieving the effect of shading and rainproofing.

[0028] Working principle: After the operator has produced and assembled the shielding assembly 4, the two vertical rods 42 can be pulled away from each other, and the two vertical rods 42 will stretch the elastic rod 43, and then the hexagonal sleeves 41 at the bottom ends of the two vertical rods 42 will be clamped on the surface of the hexagonal block, and then the two vertical rods 42 will be loosened. At this time, the two hexagonal sleeves 41 are clamped on the surface of the hexagonal block under the action of the rebound force of the elastic rod 43. Since the hexagonal sleeves 41 and the hexagonal block are mutually restricted, the hexagonal sleeves 41 will no longer move relative to the rear cover 3, and at this time the shielding plate 45 is located above the front cover 1 and the rear cover 3 and provides sunshade and rain protection for the front cover 1 and the rear cover 3;

[0029] During the process of assembling the front cover 1 and the rear cover 3, the waterproof rubber ring 12 between the front cover 1 and the rear cover 3 is adhered by double-sided tape, and then the front cover 1 and the rear cover 3 are aligned and connected inside the screw hole 13 by screws, thereby completing the assembly of the front cover 1 and the rear cover 3. After that, after the rear cover 3 is installed on the wall at a suitable position, since the cover plate 14 fixedly installed at the rear end of the rear cover 3 abuts against the wall, the rear end of the rear cover 3 will not touch the wall at this time. During the use of the access control machine, if it is not necessary to power it through the power charging port 9, the waterproof rubber plug 10 can be blocked inside the power charging port 9 to prevent rainwater from entering the power charging port 9.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
