A cash register code scanning gun based on the block chain technology

Abstract

The invention relates to a cash register code scanning gun based on the block chain technology, which includes a body, protective glass, a handle and a code scanning device; a clean mechanism and a shielding mechanism are also arranged in the main body; the shielding mechanism includes a triggering assembly, a transmission assembly, a first fixed pulley, two second elastic ropes, two first connecting wires, two rollers, two shielding curtains and two moving levers; the cleaning mechanism includes a guide rod, two first springs, two moving sleeves, two drive rods and two scrapers; the cash register code scanning gun based on the block chain technology uses the block chain technology to store data, so that that security level of the data is high, Moreover, the shielding mechanism drives theshielding curtain to move, so that the code scanning gun can be blocked by the user when the code scanning gun is not used, thereby reducing the probability of wrong operation of the code scanning gun, and the cleaning mechanism drives two scrapers to move, thereby cleaning the protective glass through the scrapers, and thereby improving the code scanning accuracy of the code scanning gun.

Description

technical field [0001] The invention relates to a cash register code scanning gun based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used, including the field of payment equipment application technology. [0004] The code scanning guns in the prior art generally adopt the traditional data encryption method, which is easy to cause data...

Problems solved by technology

[0004] The code scanning guns in the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, when some existing code scanning guns are not in use, the code scanning guns are in the working state, which makes the code scanning guns easy to Some wrong information is identified, which leads to misoperation of the code scanning gun, thereby reducing the practicability of the code scanning gun. Not only that, but in the process of using the code scanning gun in the prior art, the scanning window of the code scanning gun is easy to Accumulation of dust or adhesion of stains will cause the barcode to be blocked, thereby reducing the accuracy of the barcode scanning gun
