Description

Bar code reading equipment with protective structure Technical Field The utility model relates to the technical field of bar code reading, in particular to bar code reading equipment with a protection structure. Background The bar code reading device refers to a device for reading bar code information, which uses an optical device to convert bar space information of bar code into electronic information, and then uses a special decoder to translate the electronic information into corresponding data information. For example, the patent with the bulletin number of CN219476110U discloses bar code reading equipment capable of rapidly reading bar codes with different distances, which relates to the technical field of bar code reading and is characterized by comprising a supporting seat, wherein two clamping plates are fixedly connected to the side wall of the supporting seat, an identification head is rotatably connected between the two clamping plates, the inside of the identification head is provided with a decoding chip, a control chip, a driving chip, a voice coil motor, a lens and a photosensitive chip, the side wall of the identification head is embedded with a laser range finder and a viewfinder, the decoding chip, the driving chip, the photosensitive chip and the laser range finder are electrically connected with the control chip, and the voice coil motor is electrically connected with the driving chip. Through the arrangement, the prior art is matched with the laser range finder to quickly adjust the position of the lens, so that the adjustment of the bar code position is not needed, the zooming speed is faster, and bar codes with different distances can be quickly read. However, the bar code reading device in the prior art has the following defects in operation: The device drives the worm to rotate through rotating the handle when adjusting the angle of the identification head, and the worm is utilized to drive the tooth to rotate, so that the angle problem of the identification head is changed, but the angle adjustment efficiency of the identification head is too slow through rotating the handle, and the handle is not limited, so that the handle rotates under the action of external force, the angle of the identification head is automatically changed, and the end part of the identification head falls with dust after the device is used for a period of time, so that the device cannot identify the bar code.
