A code scanner with an anti-falling function

Abstract

The invention discloses a code scanner with an anti-falling function. The code scanner comprises a code scanner body and a protective shell. The code scanner body is embedded in a first groove formedin the top end of the protection shell, a plurality of first springs are fixedly installed at the bottom end of the first groove at equal intervals, one ends of the first springs are fixedly connectedwith the bottom end of the shell of the code scanner body, and a plurality of second grooves are formed in the groove walls of the two sides of the first groove at equal intervals. According to the code scanner with the anti-falling function, through the first spring installed in the protection shell and the air bag installed in the third groove, when the code scanner falls, a certain buffering effect is achieved, the code scanner is effectively protected, and the code scanner is prevented from being damaged by external force when falling; the second spring is used for controlling the extension and retraction of the connecting rod, so that the extension and retraction of the limiting block are controlled, and the code scanner can be firmly propped in the first groove.

Description

technical field [0001] The invention relates to a code scanner, in particular to a code scanner with an anti-drop function. Background technique [0002] A barcode scanner is a machine that reads barcode information. Use the infrared light source to emit, and then use the chip to decode according to the reflection result, and finally return the correct character represented by the barcode. [0003] Existing code scanners are generally placed on the table for use, without protection measures, and do not have the anti-drop function. When they are collided and dropped by external force, they are easy to break. Therefore, it is necessary to design a code scanner with anti-drop function . Contents of the invention [0004] The object of the present invention is to provide a code scanner with an anti-drop function to solve the problem that the existing code scanners proposed in the above background technology are usually placed on the table for use, without protective measures...
