[0002] POS means "point of sale" in Chinese. POS is a multifunctional terminal. Installing POS in merchants and credit card acceptance outlets and connecting to a computer network can realize automatic electronic fund transfer. It supports consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. The basic principle of POS system is to create product information in a computer file first. Through the computer cash register online architecture, the barcode on the product can be directly read by the optical reader on the cash register device (or the code can be directly entered by the keyboard) and the product information (unit price, department, discount...) can be displayed immediately to speed up the cash register speed and accuracy.

[0003] In the actual use of POS, due to its special purpose and financial attributes, some speculators will use POS to perform some special operations, usually disassembling the POS machine and adding other electronic components. The display screen is usually modified for intuitive observation, but the existing POS display screen does not have an anti-dismantling function, which may affect the safety of use.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a safe and tamper-proof commercial POS machine display screen, comprising a frame 1, an integrated display screen 3 is fixedly installed on the inner side of the frame 1, a horizontal card slot 5 is opened on the outer side of the frame 1, a POS shell card slot 2 is opened on the front of the frame 1, an integrated extended screen edge 14 is fixedly installed on the outer side of the integrated display screen 3, a sealing waterproof strip 4 is fixedly installed on the outer side of the integrated extended screen edge 14, a fixing plate 13 is fixedly installed on the bottom of the integrated display screen 3, and a reinforcing metal plate 8 is fixedly installed on the other side of the fixing plate 13, and the reinforcing metal plate 8 is fixedly installed on the other side of the fixing plate 13. A plurality of heat dissipation strips 12 are fixedly installed at the bottom of the metal plate 8, a plurality of cross bars 6 are fixedly plugged into the inside of the heat dissipation strips 12, column holes 17 are provided at both ends of the cross bars 6, a spring 16 is fixedly installed at one end inside the column hole 17, a round plug 7 is fixedly installed at the other end of the spring 16, and the round plug 7 is movably plugged into the inside of the cross bar 6, a protective frame 11 is fixedly installed on the back of the reinforced metal plate 8, a data connector 10 is fixedly installed on the back of the reinforced metal plate 8, a groove 15 is provided on the outer side of the integrated display screen 3, and a plurality of positioning holes 9 are provided on the inner side of the frame body 1.

[0020] The working principle of the above technical solution is as follows: during production, the structure is installed at the corresponding position of the POS, and the POS shell slot 2 is used to snap into the POS machine shell, and cooperates with the sealing waterproof strip 4 to ensure that the outer seal does not get water and reduce damage, and then the separated horizontal plug plate component is inserted into the horizontal slot 5 and the groove 15 accordingly, so that the installation and fixing mechanism of the POS machine is fixed to the horizontal slot 5 and the groove 15 accordingly. The embedded mechanism makes the integrated display screen 3 damaged and unusable when it is disassembled, so that it cannot be disassembled after production and molding, and during installation, the cross bar 6 and the round plug 7 correspond to the installation position of the POS machine. After being inserted, the round plug 7 is squeezed and contracted, and the compressed spring 16 enters the corresponding hole, so that the integrated display screen 3 cannot be disassembled after installation, which increases the stability and firmness. The overall solution improves safety, increases the difficulty of disassembly and assembly, and makes the overall structure stable.

[0021] In another embodiment, Figure 1-Figure 3 As shown, the frame 1 is divided into an upper plate and a lower plate by a transverse slot 5 , and both the upper plate and the lower plate are fixedly mounted on the outer side of the integrated display screen 3 , and the groove 15 is connected to the inner side of the transverse slot 5 .

[0022] The horizontal card slot 5 divides the frame 1 into two plates, and the lower plate is fixed to the integrated display screen 3, the fixed plate 13 and the reinforcing metal plate 8, and the upper plate is fixed to the integrated display screen 3. During production and installation, the corresponding partition plug-in mechanism of the POS machine is inserted into the horizontal card slot 5, which will block the torque of the outside of the integrated display screen 3 caused by disassembly and assembly, and when personnel who are not familiar with the modified structure pry it hard, the integrated display screen 3 will be damaged and made unusable, thereby preventing the fraudulent behavior of pretending to maintain the original after disassembly and assembly. In addition, the frame 1 can be stabilized by the socket inserted into the positioning hole 9, and can cope with the production of larger-sized display screen structures.

[0023] In another embodiment, Figure 2 and Figure 3 As shown, the outer side of the integrated extended screen edge 14 is fixedly mounted on the inner side of the frame 1 , and the two sides of the sealing waterproof strip 4 are respectively fixedly mounted on the opposite sides of the integrated extended screen edge 14 and the frame 1 .

[0024] The integrated extended screen edge 14 is an integrated extended fixed structure of the integrated display screen 3 and only has the function of fixing and sealing the seams. It does not display, reduces the possibility of warping, does not affect the appearance, and makes the torque stable.

[0025] In another embodiment, Figure 2 and Figure 3 As shown, the input end of the data connector 10 is electrically connected to the inside of the integrated display screen 3 through a wire, and the protection frame 11 is located outside the data connector 10 .

[0026] The heat dissipation strip 12 cooperates with the protection frame 11 to protect the data connector 10 to fit the bottom installation position of the POS, indirectly protecting the installation of the data input connection of the data connector 10 and increasing the difficulty of disassembly and assembly.

[0027] In another embodiment, Figure 2 and Figure 3 As shown, the fixing plate 13 passes through the lower plate of the frame 1 and extends to the bottom of the frame 1 , and the bottom of the reinforcing metal plate 8 is fixedly mounted on the bottom of the frame 1 .

[0028] By providing the heat dissipation strips 12 and the reinforcing metal plate 8, when in use, the heat generated by the integrated display screen 3 is conducted through the fixing plate 13 and the reinforcing metal plate 8 and then conducted out through the heat dissipation strips 12, so that the integrated display screen 3 can be fixed while dissipating heat, thereby increasing the service life and stabilizing the structural torque, and achieving a good overall use effect.

[0029] In another embodiment, Figure 2 As shown, the cross bars 6 are evenly distributed linearly inside the heat dissipation bars 12 , and the heat dissipation bars 12 are evenly distributed linearly on the back side of the reinforcement metal plate 8 .

[0030] The uniform distribution of the heat dissipation strips 12 and the crossbars 6 makes the structure stable during installation and use, and is easy to use. The overall structure is stable, and the moment support at the bottom is increased, making it easy to use.

[0031] 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.
