[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 This utility model provides a protective structure for an attendance access control machine, including an access control machine body 7. An external connector 8 is provided on one side of the access control machine body 7. The external connector 8 can be a USB connector or a TYPE-C connector, preferably a TYPE-C connector, for connecting external devices for data transmission. A fixing base 12 is inserted into the bottom of the access control machine body 7. A mounting hole 13 is opened on one side of the access control machine body 7, and a fixing screw passes through the mounting hole 13 and is fixed to the fixing base 12.
[0023] During installation, first fix the mounting base 12 to the wall or support frame with screws, then bring the access control machine body 7 into contact with the mounting base 12, and then use screws to pass through the mounting holes 13 to fix the access control machine body 7 to the mounting base 12, thus completing the installation of the access control machine body 7.
[0024] It should be noted that the access control machine body 7 in this utility model is existing technology, including access control board, card reader, fingerprint recognition module, etc. Those skilled in the art can purchase and set it up according to actual needs, which will not be described in detail here.
[0025] The access control machine body 7 has a fixed frame 1 fixed to its outer walls on multiple sides by bolts. A groove 14 is provided on one side of the fixed frame 1. A limit groove 15 is provided on the inner wall of one side of the groove 14. A protective frame 2 is provided in the groove 14, and the protective frame 2 covers the outer connector 8 and the mounting hole 13. The top of the protective frame 2 is flush with the top of the fixed frame 1. Both ends of the protective frame 2 are integrally formed with limit strips 16. The horizontal cross section of the limit strip 16 is an inverted trapezoid or an L-shape, preferably an inverted trapezoid. The top of the fixed frame 1 is provided with a protective component to protect the touch area of the access control machine body 7.
[0026] When the protective frame 2 is installed into the groove 14, the limiting strip 16 will be inserted into the limiting groove 15. Since the limiting strip 16 is an inverted trapezoid or L-shaped, the protective frame 2 will not fall off due to gravity. While the protective frame 2 is blocked by the reinforcement component, the access control machine body 7 is also protected, so that both the access control machine body 7 and the external connector 8 are protected, thereby extending the service life of the external connector 8.
[0027] The enhanced protection components include a protective cover 4 that rotates on top of the fixed frame 1. The top of the protective cover 4 has a touch hole 5, which is positioned to avoid obstructing the fingerprint recognition module of the access control machine body 7, thus not affecting the fingerprint recognition of the access control machine body 7. A placement groove is provided through the top of the protective cover 4, and a transparent window 6 is fixed in the placement groove by bolts. The transparent window 6 is made of acrylic sheet or tempered glass and protects the display screen of the access control machine body 7. It can protect the access control machine body 7 without affecting its normal function, thereby improving the protection effect of the access control machine body 7. A limiting component is provided on one side of the fixed frame 1 to fix the protective cover 4.
[0028] The limiting component includes an elastic bracket 3 fixed to one side of the fixed frame 1. The elastic bracket 3 is preferably made of elastic metal or elastic plastic, and more preferably elastic steel. A slot 11 is provided on one side of the protective cover 4. After the protective cover 4 is closed, one end of the elastic bracket 3 is inserted into the slot 11, thereby locking the angle and position of the protective cover 4, so that the protective cover 4 can be fixed for a long time, thereby providing long-term protection for the access control machine body 7 and long-term blocking for the protective frame 2, improving the stability of the access control machine protection.
[0029] The top of the fixed frame 1 is rotatably connected to two support rods 10, and the inner wall of the top of the protective cover 4 is integrally formed with a limit block 9. When it is necessary to use the digital input on the access control machine body 7, rotate the protective cover 4 to expose the digital input keyboard, and then rotate the support rods 10 so that one end of the support rods 10 abuts against the limit block 9, thereby supporting the protective cover 4, which facilitates the input of numbers and improves the ease of use of the access control machine.
[0030] The specific implementation steps of the access control machine in this application are as follows:
[0031] First, fix the mounting base 12 to the wall or support frame with screws. Then, make contact between the access control machine body 7 and the mounting base 12. Then, use screws to pass through the mounting holes 13 to fix the access control machine body 7 to the mounting base 12, thus realizing the installation of the access control machine body 7.
[0032] Install the protective frame 2 into the groove 14. At this time, the limiting strip 16 will be inserted into the limiting groove 15, so that the protective frame 2 covers the external connector 8 and the mounting hole 13, thereby isolating the external connector 8 and the mounting hole 13 from the outside. Then rotate the protective cover 4 so that one end of the elastic bracket 3 is inserted into the slot 11, thereby locking the angle and position of the protective cover 4, thereby limiting the protective frame 2 and protecting the access control machine body 7, and improving the service life of the access control machine.
[0033] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
[0034] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
