[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.

[0020] Example

[0021] See also Figure 1-2 The utility model provides a technical solution: an MPOS machine lens anti-disassembly structure, comprising a bottom shell 1, wherein the bottom shell 1 is provided with a positioning hole 2 and a main board 3, wherein the main board 3 is provided with a switch assembly for preventing the lens from being maliciously disassembled, at which time the two pins 501 are away from the circuit to disconnect the circuit, and when the circuit is switched on and off, it is judged as maliciously disassembled in the protection logic, and the protection mechanism is triggered at the same time, the self-destruction program is started, and the sensitive data in the device is cleared, so as to achieve the purpose of protecting the device and prevent important information from being tampered with or leaked.

[0022] In this embodiment, all electrical components are controlled by conventional controllers.

[0023] For example, please refer to Figure 1-4 The mainboard 3 is provided with a bracket 7 and a rubber strip 9 on the outside, and a through groove 701 is provided inside the bracket 7 and the rubber strip 9. The inner wall of the bracket 7 is provided with a plurality of fixing bolts 8, and the inner wall of the bottom shell 1 is provided with a plurality of positioning holes 2. The mainboard 3 is inlaid and connected with the inner wall of the bottom shell 1, and the installation frame 4 is adhesively connected with the inner wall of the mainboard 3.

[0024] During installation, the switch assembly is adhered to the PCB board (main board 3), the main board 3 is installed on the bottom shell 1, the bracket 7 is installed on the main board 3, and the fixing bolts 8 are respectively corresponding to the positioning holes 2 on the bottom shell 1 and tightened.

[0025] Example 1

[0026] Please refer to the attached Figure 3 , 4 As shown, the switch assembly includes a mounting frame 4 arranged inside the main board 3, a pressing plate 5 and a connecting rod 6 are arranged inside the mounting frame 4, two pins 501 are arranged at the bottom of the pressing plate 5, a bump 601 is arranged at the other end of the connecting rod 6, a magnetic block 602 is arranged on the outer wall of the bump 601, and an electromagnet 401 is arranged on the inner wall of the mounting frame 4. The bump 601 serves as a switch movable sheet, and the two pins 501 at the bottom of the pressing plate 5 are respectively two breakpoint guide rods of the circuit. When the lens is installed and pressed against the bump 601 to make it shrink into the mounting frame 4, the bump 601 squeezes the pressing plate 5 to extend the two pins 501 to abut against the circuit to be electrically connected and energized. When the lens is removed and the bump 601 lacks pressing force, the spring in the mounting frame 4 pushes the bump 601 to rotate and extend outward;

[0027] The electromagnet 401 is connected to the inner wall of the mounting frame 4 through bolts, and the electromagnet 401 is magnetically connected to the magnetic block 602. The pressing plate 5 is located in the mounting frame 4 and is slidably connected to the inner wall of the mounting frame 4 through a slide rail. One end of the two pins 501 is located in the mounting frame 4 and is connected to the pressing plate 5, and the other end is electrically connected to the circuit of the MPOS machine. One end of the connecting rod 6 is rotatably connected to the inner wall of the mounting frame 4 through a fixed axis, and the other end is connected to the protrusion 601 through a bolt. The protrusion 601 is an arc structure and can extend to the outside through the top opening of the mounting frame 4. The protrusion 601 can abut against the lens, and the magnetic block 602 is connected to the outer wall of the protrusion 601 through bolts. The mounting frame 4 can pass through the bracket 7 and the through groove 701 in the rubber strip 9 and be close to the lens. The fixing bolt 8 passes through the bracket 7 and the main board 3 and extends to the positioning hole 2 inside the bottom shell 1.

[0028] When the lens needs to be removed without damage during maintenance, the electromagnet 401 in the mounting frame 4 is energized through data control to generate a magnetic pole to magnetically connect with the magnetic block 602 to push the protrusion 601 to retract into the mounting frame 4, so that the pin 501 is still in a connected state when the lens is removed;

[0029] The mounting frame 4 is adhered to the PCB board (main board 3), the main board 3 is mounted on the bottom shell 1, the bracket 7 is mounted on the main board 3, and the fixing bolts 8 are respectively corresponding to the positioning holes 2 on the bottom shell 1, and are tightened and fixed. Among them, the mounting frame 4 passes through the through slots 701 in the bracket 7 and the rubber strip 9, and the protrusion 601 of the micro switch is in a pop-up protruding state. When the lens and the rubber strip 9 are assembled on the bracket 7 as a whole, they are pressed and fitted with the bracket 7, and the protrusion 601 contacts the lens and is pressed down by the lens. At this time, the pin 501 in the mounting frame 4 is connected to the circuit, that is, the whole machine is installed;

[0030] When in use, first when the lens is removed, the protrusion 601 lacks pressure when the lens is removed, so the spring at the bottom of the pressing plate 5 pushes the pressing plate 5 and the protrusion 601 to rise, and the pin 501 shrinks into the mounting frame 4, thereby disconnecting from the circuit. When the circuit changes on and off, the protection mechanism is triggered to achieve the purpose of protecting data; when the lens needs to be removed without damage during maintenance, the electromagnet 401 in the mounting frame 4 is energized through data control to generate a magnetic pole that is magnetically connected to the magnetic block 602, pushing the protrusion 601 to shrink into the mounting frame 4, so that the pin 501 is still in a connected state when the lens is removed.

[0031] The working process of the utility model is as follows: when the lens is removed during use, the protrusion 601 is lifted up by the spring at the bottom of the pressing plate 5 because of the lack of pressure when the lens is removed, and the pin 501 is retracted into the mounting frame 4, thereby being disconnected from the circuit. When the circuit is switched on and off, the protection mechanism is triggered to achieve the purpose of protecting data; when the lens needs to be removed without loss during maintenance, the electromagnet 401 in the mounting frame 4 is energized through data control to generate a magnetic pole that is magnetically connected to the magnetic block 602, pushing the protrusion 601 to retract into the mounting frame 4, so that the pin 501 is still in a connected state when the lens is removed. The utility model realizes the protection of data when the POS machine is maliciously disassembled, avoids data leakage, and is convenient for production and assembly, as well as subsequent maintenance.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
