A multifunctional bar code scanning gun

Abstract

The invention relates to the technical field of code scanning guns. The invention further discloses a multifunctional bar code scanning gun. The device comprises a scanning gun body, Data connecting line and fixing seat, the bottom of the scanning gun body is fixedly connected with a mounting block; a placement box is fixedly connected to the top of the fixed seat; an opening matched with the mounting block is formed in the top of the placing box; first grooves are formed in the inner walls of the four sides of the placement box; A clamping block is arranged in each first groove, sliding blocks are fixedly connected to the two side walls of each clamping block, sliding grooves matched with the sliding blocks are formed in the two side walls of each first groove, the sliding blocks are slidably connected with the sliding grooves, first springs are arranged in the four first grooves, and the two ends of each first spring are fixedly connected with the side walls of the clamping blocks and the bottoms of the first grooves correspondingly. The multifunctional bar code scanning gun can be used in a handheld mode when a large object is scanned, the code scanning gun is fixedly used underother conditions, meanwhile, the scanning head can be protected, and the scanning head is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of barcode scanning guns, in particular to a multifunctional barcode scanning gun. Background technique [0002] Most shopping malls and supermarket cash registers now use barcode scanning equipment to scan the barcodes of various types of products purchased by customers, and then send the barcode information to the computer for automatic settlement. The barcode scanning equipment emits light from the light source and irradiates the barcode symbol through the optical system, and the reflected light is imaged on the photoelectric converter through the optical system to generate an analog voltage signal, which is then filtered and shaped. The decoder interprets it as a computer Digital signals that can be directly accepted to achieve the functions of identification and judgment. [0003] In the prior art, most of the code-scanning guns in supermarkets are fixed, which is not convenient for people to use when ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multifunctional barcode scanning gun that can be used handheld when scanning large objects, and can be used fixedly in other cases, while protecting the scanning head. The advantage of preventing damage is to solve the problem that most of the code scanning guns in the supermarket are fixed. When the fixed type scans large objects, it is not convenient for people to use. At the same time, the scanning head of the code scanning gun is protected. mechanism, prone to damage problems
