Abstract

The invention relates to the technical field of two-dimensional codes, and discloses a two-dimensional code instrument card anti-falling structure which is characterized in that an adjusting assemblyis mounted on the rear surface of a mounting plate, a placement groove is formed in the mounting plate, and a first protection groove communicating with the placement groove is formed in the upper surface of the mounting plate; and a second protection groove communicating with the placement groove is formed in the lower surface of the mounting plate, and a clamping assembly is mounted in the placement groove. A user can conveniently move the two-dimensional code instrument card left and right through the adjusting assembly, so that the two-dimensional code instrument card is easily adjusted toan ideal position to be used, the application range is widened, and the adjusting assembly is high in adjusting precision and is easy to use practically. By means of the clamping assembly, a user canconveniently and rapidly disassemble and assemble the two-dimensional code instrument card, the disassembly and assembly time of the two-dimensional code instrument card is shortened, meanwhile, theclamping assembly can also be used for clamping the two-dimensional code instrument cards of different heights, and the anti-disengaging effect is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a two-dimensional code device card fall-off prevention structure. Background technique [0002] Two-dimensional code is also called two-dimensional barcode. The most common form is QR Code. The full name of QR is Quick Response. It is a very popular coding method on mobile devices in recent years. It can store more data than traditional Bar Code Information can also represent more data types. Most of the existing two-dimensional codes are sprayed on the device card, and most of the two-dimensional code device cards need to be fastened by the anti-falling structure during use, which is convenient. actual use. [0003] However, during the use of the existing anti-falling structure, on the one hand, the two-dimensional code device card is prone to loosening, and the anti-falling effect is not ideal; on the other hand, it is difficult to move the two-dimensional code d...
