Portable two-dimensional code reading device

Abstract

The invention discloses a portable two-dimensional code reading device. The device comprises a machine shell, a connecting ring and a cover plate; the connecting ring is fixedly connected to one sideof the machine shell; the upper part of the connecting ring is in bolted connection with a connecting belt; the other end of the connecting belt is in bolted connection with a finger ring; a scanningwindow is formed in the upper part of the machine shell; the cover plate is arranged on one side of the scanning window; a connecting box is arranged on the upper side of the cover plate; a sleeve rodis arranged at the upper part of the connecting box; a connecting rod is arranged in the sleeve rod in a sleeving mode; a sliding plug is fixedly connected to the upper end of the connecting rod; a spring is fixedly connected to the upper side of the sliding plug; and a limiting block is fixedly connected to the lower end of the connecting rod. The two-dimensional code scanning device can be fixed in the wrist, and a finger is sleeved with the finger ring, so that the device can be prevented from falling off, personnel can better protect the scanning device, and the loss of the code scanningdevice due to the fact that an activity site is hectic is avoided; and the cover plate is further arranged at the upper part of the device, so that the scanning window can be covered when the device is not used, and the damage can be avoided.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code reading devices, in particular to a portable two-dimensional code reading device. Background technique [0002] The two-dimensional code uses a specific geometric figure to record data symbol information in a black and white graphic distributed on a plane according to a certain rule. In the code compilation, the "0" and "1" bit streams that constitute the internal logic basis of the computer are cleverly used. The concept of using a number of geometric shapes corresponding to binary to represent text and numerical information, and automatically read through image input devices or photoelectric scanning devices to realize automatic processing of information. At present, many merchants scan two-dimensional codes. It is very convenient to collect money, but if you need to do activities outside, it is not convenient enough to carry the code scanner. If the event site is busy, it is easy t...

The concept of using a number of geometric shapes corresponding to binary to represent text and numerical information, and automatically read through image input devices or photoelectric scanning devices to realize automatic processing of information. At present, many merchants scan two-dimensional codes. It is very convenient to collect money, but if you need to do activities outside, it is not convenient enough to carry the code scanner. If the event site is busy, it is easy to lose or damage the code scanner, causing economic losses
