[0032] Embodiment

[0033] As Figures 1-4As shown in the figure, an explosion-proof barcode scanner proposed by the present utility model includes a barcode scanner main body 1 and a bracket 2 for placing the barcode scanner main body 1. The barcode scanner main body 1 further includes a scanning head 11 and a handle 12. An anti-slip gasket 13 is adhered to the outer wall of the handle 12. Through the setting of the anti-slip gasket 13, the anti-slip property of the barcode scanner main body 1 is improved. The handle 12 is fixedly connected to the scanning head 11. The bracket 2 includes a supporting rod 22 for placing the handle 12 and a placing seat 24 for placing the scanning head 11. Two groups of supporting rods 22 are fixedly installed on the top of the base 21, and the placing seat 24 is fixedly installed on the top of the other end of the base 21. An anti-slip pad 23 is provided on the concave surface of the top of the supporting rod 22, and the anti-slip pad 23 fits with the outer surface below the handle 12. The handle 12 is partially supported by the supporting rod 22 and the anti-slip pad 23.

[0034] A cavity 241 is opened in the placing seat 24. A groove is opened at the top of the cavity 241. A pressure sensor 3 is installed on one inner wall of the groove. The pressure sensor 3 is communicatively connected to the control end of the driving motor 251. The scanning end of the scanning head 11 is placed in the groove, and a guiding hole 242 penetrating the top of the cavity 241 is opened in the groove. A driving cleaning assembly 25 is installed in the cavity 241.

[0035] As Figure 3 and Figure 4 shown, the driving cleaning assembly 25 includes a driving motor 251 installed in the cavity 241. The output end of the driving motor 251 is fixedly connected to a threaded rod 252. The end of the threaded rod 252 away from the driving motor 251 is rotatably arranged on the inner wall of the cavity 241. A threaded sleeve 253 is sleeved on the threaded rod 252. A micro cylinder 254 is installed on the top of the threaded sleeve 253. An orientation block is further fixedly connected to the outside of the micro cylinder 254. The orientation block is slidably arranged on the inner wall of the guiding hole 242. The output end of the micro cylinder 254 is fixedly connected to a mounting bracket 255. The mounting bracket 255 is of a "U" - shaped structure. A cleaning roller 256 is rotatably installed on the top of the micro cylinder 254. Both ends of the cleaning roller 256 are rotatably arranged on the two inner walls of the mounting bracket 255.

[0036] In this embodiment, after the main body 1 of the barcode scanner is used, it is placed on the top of the bracket 2. The handle 12 is placed between the tops of the two supporting rods 22, and the scanning end of the scanning head 11 is placed in the groove of the placing seat 24. When the scanning end of the scanning head 11 is placed into the groove, it will squeeze the pressure sensor 3 arranged on the inner side of the groove. The pressure sensor 3 then sends an instruction to start the control end of the driving motor 251. The start of the driving motor 251 causes the threaded sleeve 253 sleeved on its outer ring to move horizontally under the limiting and guiding action of the top micro cylinder 254 and the guiding block in the guiding hole 242. At the same time, the output end of the activated micro cylinder 254 pushes, and the mounting frame 255 and the cleaning roller 256 are pushed under the lens mirror surface of the scanning end of the scanning head 11. The cleaning roller 256 follows the movement of the threaded sleeve 253 to clean the stains, dust, etc. on the lens mirror surface, realizing the automatic cleaning of the scanning end and improving the scanning and recognition accuracy. It should be noted that the cleaning roller 256 can be replaced and disassembled regularly.

[0037] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
