Description

Cross-border financial data preprocessing system and method Technical Field

[0001] The present invention relates to the technical field of financial data preprocessing, and in particular to a cross-border financial data preprocessing system and method. Background Art

[0002] Financial business generally refers to financial services. Financial institutions are financial intermediaries engaged in financial services and are part of the financial system. The financial services industry encompasses banking, securities, insurance, trusts, and funds. Accordingly, financial intermediaries also include banks, securities firms, insurance companies, trust and investment companies, and fund management companies. Cross-border finance refers to a model in which transacting groups from different regions and types conduct business through financial platforms. With the continuous expansion of cross-border financial business, the resulting financial risks cannot be ignored. Cross-border finance refers to cross-border financial activities in international financial markets, including currency transfers, foreign exchange transactions, international investments, cross-border loans, and financial operations in foreign markets. Cross-border finance is a crucial component of international economic cooperation and globalization, playing a key role in promoting economic exchange and cooperation among countries. Technical issues

However, existing analysis devices are not convenient to store after use and are exposed to the air. If you are not careful, the display screen may be easily scratched. In addition, the exposed display screen surface will absorb dust, which will damage the display screen over time and make it unusable. In response to the above problems, the inventors proposed a cross-border financial data preprocessing system and method to solve the above problems. Technical Solutions

[0040] By adopting the above technical solution, when the protective plates 201 slide towards each other, the cleaning roller 204 can roll on the surface of the display screen 107 and clean the dust on its surface. Therefore, while the protective plates 201 provide protection, the dust can also be cleaned to prevent the surface of the display screen 107 from absorbing dust, which may damage the display screen 107 over time and make it unusable.

[0041] Dustproof devices 3 are installed on both sides of the placement frame 101. The dustproof device 3 includes a dustproof frame 301. A dustproof net 302 is installed in the dustproof frame 301. A positioning block 303 is fixedly provided on one side of the dustproof frame 301. A movable groove 102 is provided in the placement frame 101. The positioning block 303 is movably provided in the movable groove 102. A moving block 103 is slidably provided in the movable groove 102.

[0042] By adopting the above technical solution, the heat dissipated by the display screen 107 is drawn out from the vent 106 by turning on the heat dissipation fan 304 to dissipate the heat, and dust is prevented from entering the display screen 107 through the dustproof net 302.

[0043] Working principle: First, by turning on the motor 401, the bidirectional screw rod 402 is driven to rotate, and then the two threaded blocks 404 drive the protective plate 201 to slide toward each other on one side of the placement frame 101, so that the display screen 107 can be protected after use, so as to prevent the display screen 107 from being inconvenient to store after use and being exposed to the air, which may easily scratch the display screen 107 if not paid attention to. The second active bevel gear 403 and the second driven bevel gear 406 are engaged, so that when the bidirectional screw rod 402 rotates, the transmission rod 405 can be driven to rotate, and then the guide block 411 drives the T-shaped block 412 to slide in the placement frame 101, and the connecting rod 409 is rotated in the first ear plate 408 and the second ear plate 410, so that the extension plate 407 can be pushed out, and the data can be explained and analyzed;

[0044] When the protective plates 201 slide toward each other, the cleaning roller 204 can roll on the surface of the display screen 107 and clean the dust on the surface thereof, so that the protective plates 201 can protect the display screen 107 while also cleaning the dust. The mounting groove 202 provided in the protective plate 201 is aligned with the groove provided in the placement frame 101, and the first active bevel gear 207 and the first driven bevel gear 209 are engaged. By rotating the rotating shaft 206, the threaded rod 208 can be driven to rotate, prompting the movable plate 210 to drive the positioning rod 211 to disengage from the mounting block 205. The mounting block 205, the rotating rod 203 and the cleaning roller 204 are integrated, and can be taken out of the mounting groove 202 to facilitate cleaning or replacement of the cleaning roller 204. After the replacement is completed, the positioning rod 211 is inserted into the mounting block 205 to fix the cleaning roller 204.

[0045] By pulling the movable block 103 and squeezing the spring 105, the spring 105 is deformed, so that the insertion rod 104 is disengaged from the positioning block 303. Then the dustproof frame 301 can be removed, the dust on the surface of the dustproof net 302 can be cleaned, and then the dustproof frame 301 can be installed again to ensure heat dissipation.

[0046] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
