[0002] As a high-tech product that closely combines optics, mechanics, electronics, and software applications, the scanner gun is the third generation of major computer input devices after the keyboard and mouse. With the development of technology, the use of cash is becoming less and less. Cash registers in supermarkets and shopping malls are equipped with barcode scanners for scanning and payment. Traditional barcode scanners are generally gun-shaped and can be used at any time. In supermarket cashiers, the general steps are to first scan the product code through the product scanner, then pick up the barcode scanner to scan the barcode for payment, and put it down after the payment is completed, thus completing a payment process;
[0003] In daily use, traditional barcode scanners are prone to accumulate dust, debris or other tiny particles because their scanning ports are exposed to the external environment. After a long period of accumulation, these impurities will accumulate around the scanning port or enter the inside of the scanning port, seriously affecting the scanning accuracy and effect of the barcode scanner. For this reason, we urgently need to provide a barcode scanner.
[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a barcode scanning gun, referring to Figure 1-Figure 3The utility model comprises a body 1, a code scanning port 4 is provided at one end of the body 1, and a dust cover 7 is provided on the outer side of the code scanning port 4. By installing the dust cover 7, the dust-proof effect of the code scanning port 4 is improved and the service life is enhanced. L-shaped fixing plates 5 are fixedly connected on both sides of one end of the body 1 close to the code scanning port 4, and limiting holes 6 are provided on the surfaces of the L-shaped fixing plates 5. Elastic plates 8 are fixedly connected on both sides of one end of the dust cover 7 close to the code scanning port 4, and connecting columns 9 are fixedly connected on the outer surfaces of the two elastic plates 8. The two connecting columns 9 are respectively connected to the inside of the limiting holes 6. The two elastic plates 8 on the inner side of the dust cover 7 are connected to the inner sides of the two L-shaped fixing plates 5, and then connected to the inside of the limiting holes 6 through the connecting columns 9. The dust cover 7 is fixed to the front end of the code scanning port 4 by the rebound force of the two elastic plates 8 to the outside, which has a good dust-proof effect on the device when it is placed in daily life, and the installation and disassembly are relatively simple and quick, so as to avoid the code scanning port 4 being exposed to the external environment and easily accumulating dust, debris or other tiny particles.
[0020] Reference Figure 2-Figure 3 A handle 2 is installed at the bottom of the fuselage 1, and a button 3 is fixedly installed on the upper end of the handle 2. Short arms 10 are rotatably connected to the two side surfaces of the dust cover 7. Long arms 11 are provided at the other ends of the two short arms 10. Connecting rods 12 are fixedly connected to the connection between the two long arms 11 and the short arms 10. The long arms 11 are rotatably connected to the inner side of the short arms 10 through the connecting rod 12. A through hole 13 is opened at one end of the long arm 11 away from the short arm 10. Fixed rods 14 are fixedly connected to the two side surfaces of the fuselage 1. The outer side of the fixing rod 14 is connected to the inside of the through hole 13, and the long arm 11 is rotatably arranged on both sides of the fuselage 1 through the through hole 13 and the fixing rod 14. Through the mutual cooperation between the short arm 10 and the upper arm 11, it is convenient to keep the dust cover 7 outside the fuselage 1 when it is removed, and it will not be lost, which improves the convenience. When the dust cover 7 is installed, the short arm 10 and the long arm 11 can be used to cooperate to install the dust cover 7 at the front end of the code scanning port 4, which saves the time of finding the dust cover 7.
[0021] The implementation principle of a barcode scanning gun in an embodiment of the present application is as follows: when the barcode scanning gun is not in use, the two elastic sheets 8 are pinched to connect them to the inner sides of the two L-shaped fixing sheets 5, and at the same time, the outer sides of the connecting columns 9 are aligned with the insides of the two limiting holes 6, and then the two elastic sheets 8 are loosened to connect the connecting columns 9 to the insides of the limiting holes 6, thereby fixing the dust cover 7. When disassembling, it is only necessary to pinch the two elastic sheets 8 and move them inward so that the connecting columns 9 fall off the insides of the limiting holes 6, and then pull the dust cover 7 outward, and cooperate with the short arm 10 and the long arm 11 to move the dust cover 7 to the upper end of the body 1, so that the barcode scanning port 4 is exposed, and the barcode scanning work can be carried out.
