The light box 150 is rectangularly arranged. An extension part 154 extends outwardly from a side of the light box housing 156 corresponding to the extension part 126 and a sensor 155 is embedded therein. A plurality of second engaging elements 151 are provided on the light box housing 156. Among them, the sensor 155 contains relevant information about the picture card 130 that needs to be detected on the light box 150 side. The sensor 155 can be used to read whether the relevant information about the picture card 130 on the electronic tag 127 matches the relevant information about the picture card 130 detected on the light box 150 side, so as to determine whether the electronic tag 127 of the picture card module 110 is compatible with the sensor 155 of the light box 150, and the picture card module 110 that is adaptively selected can be carried out through the above method. When the picture card module 110 is combined with the light box 150, the sensor 155 of the light box 150 reads the electronic tag 127 of the picture card module 110 and detects the relevant information about the picture card 130 in the electronic tag 127 to confirm the correctness of replacing the picture card 130, but not limited thereto.
[0019] Among them, in order to describe in detail the cooperation mode between the substrate 140 and the graphic card 130 of the graphic card display device 10 of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 . Figure 1 is a schematic exploded view of the structure of the graphic card display device 10 according to an embodiment of the present invention, Figure 2 is a schematic exploded view of the structure of the graphic card display device 10 viewed from another angle according to an embodiment of the present invention, Figure 1 and Figure 3 is a schematic assembly structure diagram of the graphic card module 110 and the light box 150 of the graphic card display device 10 according to an embodiment of the present invention, Figure 4 is a schematic assembly structure diagram of the graphic card display device 10 viewed from another angle according to an embodiment of the present invention, Figure 3 . In an embodiment of the present invention, an installation groove 141 is provided at a position of the substrate 140 corresponding to the graphic card 130, and is used to install the graphic card 130. Specifically, when assembling the substrate 140 and the graphic card 130, the graphic card 130 can be placed on the installation groove 141 of the substrate 140 to ensure that the graphic card 130 can be accommodated and placed on the substrate 140, but not limited thereto.
[0020] Among them, in order to describe in detail the cooperation mode between the cover plate 120 and the substrate 140 of the graphic card display device 10 of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4.

Two positioning pins 122 and two first positioning holes 125 are respectively arranged at the two side corners of the cover plate 120. Among them, the positioning pin 122 is used to pass through the first positioning hole 125, and two second positioning holes 142 are respectively arranged at the two side corners of the substrate 140. When the substrate 140 is to be combined with the cover plate 120, after the positioning pin 122 is first installed by passing through the first positioning hole 125, the positioning pin 122 is then inserted and installed on the second positioning hole 142. Specifically, when the graphic card module 110 is to be assembled, first place the graphic card 130 on the installation groove 141 of the substrate 140, and then cover the cover plate 120 on the substrate 140, and ensure that the graphic card 130 is fixed between the cover plate 120 and the substrate 140. By the way, when the cover plate 120 is combined with the substrate 140, it is necessary to ensure that the second positioning hole 142 of the substrate 140 is not blocked by the first positioning hole 125 of the cover plate 120, so as to prevent the positioning pin 122 from being unable to be inserted into the second positioning hole 142 after being inserted into the first positioning hole 125, and further unable to ensure that the cover plate 120 and the substrate 140 are locked together. In other words, the installation positions of the first positioning hole 125 and the second positioning hole 142 can be set to coincide, and further ensure that after the cover plate 120 and the substrate 140 are combined, the positioning pin 122 can be first inserted into the first positioning hole 125, and then the positioning pin 122 can be inserted into the second positioning hole 142. Through the above setting method, the cover plate 120 and the substrate 140 are locked by inserting the positioning pin 122, so that the graphic card module 110 forms an integral whole, and reference can be made to Figure 3 and Figure 4 , but not limited thereto.
[0021] Among them, in order to describe in detail the cooperation method between the graphic card module 110 of the graphic card display device 10 of the present utility model and the light box 150, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 . Figure 5It is an installation schematic diagram of the graphic card display device 10 according to an embodiment of the present utility model. In an embodiment of the present utility model, two first engaging elements 121 are respectively provided on both sides of the cover plate 120. The light box 150 has a light box housing 156, and two second engaging elements 151 are respectively provided on both sides of the light box housing 156, and the second engaging element 151 is engaged with the first engaging element 121 of the graphic card module 110. In an embodiment of the present utility model, the cover plate 120 is further provided with a plurality of through holes 123, two of which are between the first engaging element 121 and the positioning pin 122 on one side of the cover plate 120, or one of which is between two of the first engaging elements 121 on the other side of the cover plate 120. The light box housing 156 is further provided with a plurality of guiding elements 152, two of which are adjacent to two of the second engaging elements 151 on one side of the light box housing 156, or one of which is between two of the second engaging elements 151 on the other side of the light box housing 156, and the guiding element 152 is installed in a matching manner with the through hole 123. Among them, the installation positions of the first engaging element 121 and the second engaging element 151 are set to coincide, and the installation positions of the through hole 123 and the guiding element 152 are set to coincide, so as to prevent the first engaging element 121 and the second engaging element 151 from being unable to be installed in a matching manner due to the installation positions of the first engaging element 121 and the second engaging element 151 not being in the same place when the cover plate 120 is combined with the light box housing 156, and further prevent the cover plate 120 from being unable to be combined with the light box housing 156. At the same time, the through hole 123 and the guiding element 152 are the same as the first engaging element 121 and the second engaging element 151 described above, and prevent the cover plate 120 from being unable to be combined with the light box housing 156 due to the installation positions of the through hole 123 and the guiding element 152 not being in the same place. Furthermore, through the above setting method, the cover plate 120 can be installed in a matching manner with the light box housing 156. It should be noted that a light emitting element 153 is provided inside the light box housing 156, and the light emitting surface of the light emitting element 153 is arranged facing the cover plate 120, but not limited thereto. In short, when the graphic card module 110 is to be combined with the light box 150, the guiding element 152 is inserted and installed in the through hole 123, and the first engaging element 121 and the second engaging element 151 are installed in a matching manner, so that the light box housing 156 and the cover plate 120 are combined with each other. It should be noted that at this time, the cover plate 120 has been inserted and installed in the second positioning hole 142 after being inserted and installed in the first positioning hole 125 by means of the positioning pin 122, so as to make the cover plate 120 drive the substrate 140, so that the light box 150 and the graphic card module 110 are installed in a matching manner, but not limited thereto.
[0022] Incidentally, in an embodiment of the present utility model, an extension portion 126 extends outwardly from one side of the cover plate 120, and an electronic tag 127 is provided on the extension portion 126. It should be noted that the user can input the relevant information of the graphics card 130 in the graphics card module 110 into the electronic tag 127 through programming with the help of a computer, so that the relevant information of the graphics card 130 installed on the graphics card module 110 is set on the electronic tag 127, and the relevant information of each electronic tag 127 corresponds one-to-one to the relevant information of each graphics card 130. In an embodiment of the present utility model, an expansion portion 154 extends outwardly from one side of the light box housing 156 corresponding to the extension portion 126, and a sensor 155 is embedded in the expansion portion 154. The relevant information of the graphics card 130 that needs to be detected in the light box 150 is covered in the sensor 155. The sensor 155 is used to read whether the relevant information of the graphics card 130 on the electronic tag 127 of the cover plate 120 is consistent with the relevant information of the graphics card 130 that needs to be detected by the sensor 155 on the light box 150. In other words, when the above-mentioned graphics card module 110 is combined with the light box 150, at this time, the relevant information of the graphics card 130 in the graphics card module 110 is covered in the electronic tag 127, so that the sensor 155 can read the relevant information of the graphics card 130 in the electronic tag 127, and then the sensor 155 can sense the accuracy of the relevant information of the graphics card 130 in the electronic tag 127, so as to achieve the purpose of detecting the correctness of the graphics card 130, so as to confirm whether the relevant information of the graphics card 130 on the electronic tag 127 in the graphics card module 110 corresponds one-to-one to the relevant information of the graphics card 130 to be detected by the sensor 155 in the light box 150, to prevent the situation that the sensor cannot sense or the graphics card 130 does not match when different graphics card modules 110 and different light boxes 150 are combined, but not limited thereto.
[0023] In addition, both the first engaging element 121 and the second engaging element 151 are magnetic elements, and the first engaging element 121 and the second engaging element 151 are adsorbed and combined by magnetic force. Of course, the first engaging element 121 and the second engaging element 151 are not limited to the above-mentioned magnetic elements, and can also be clamping elements, and the first engaging element 121 and the second engaging element 151 are clamped and combined by clamping, but not limited thereto.
[0024] Incidentally, in some embodiments of the present utility model, when the light box 150 detects the test card 130, the light-emitting surface of the light-emitting element 153 faces the test card module 110, and the light-emitting element 153 may also have a rectangular array with multiple groups of light-emitting elements, but this is not limited thereto. Among them, when the test card module 110 is combined with the light box 150, if the sensor 155 senses that the relevant information of the electronic tag 127 of the test card module 110 regarding the test card 130 is incorrect or has errors, the sensor 155 will issue a warning reminder to inform the user that the electronic tag 127 adapted to the sensor 155 needs to be replaced, that is, the test card module 110 that needs to be replaced. When the sensor 155 senses that the relevant information of the electronic tag 127 of the test card module 110 regarding the test card 130 is correct or has no errors, the sensor 155 will not issue a warning reminder, that is, at this time, the sensor 155 detects that the electronic tag 127 after the combination of the test card module 110 and the light box 150 is adapted or correct. The sensor 155 can also use other notification reminders or lighting displays to inform the user of the result of the sensor 155 detecting the relevant information of the test card 130, but this is not limited thereto.
[0025] In addition, in some other embodiments of the present utility model, when it is necessary to replace different test cards 130, for the convenience of disassembly and replacement, it is not necessary to disassemble and replace the test card 130 in the test card module 110 that has been locked by the positioning pin 122. Instead, a test card module 110 corresponding to each test card 130 can be installed, and the test card module 110 can be directly replaced according to the actual situation, and then find the electronic tag 127 of the test card module 110 corresponding to the sensor 155 of the light box 150, but this is not limited thereto.
[0026] In summary, for the test card display device 10 of the present utility model, when the test card 130 is disposed between the cover plate 120 and the substrate 140, the positioning pin 122 first passes through and is inserted into the first positioning hole 125 and then is inserted into the second positioning hole 142 to lock the cover plate 120, the test card 130, and the substrate 140 to form a whole, that is, the test card module 110. When the test card module 110 is combined with the light box 150, the guiding member 152 is snap-fitted and installed in the through hole 123, the first coupling element 121 and the second coupling element 151 are adsorbed in a matching manner, and the sensor 155 of the expansion part can read the relevant information of the test card 130 in the electronic tag 127 of the expansion part, so as to ensure the accuracy of the replacement of the test card 130, and also improve the convenience of replacing the test card 130 by the installation method of the test card module 110.
[0027] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
