Technical Field

[0001] The utility model relates to the technical field of thermal desktop bar code printers, in particular to a fixing structure for a thermal sheet protection cover of a thermal desktop bar code printer. Background Art

[0002] The thermal desktop bar code printer is a small printing device widely used in the fields of commerce, logistics, manufacturing, etc. By heating the chemical coating on the surface of the thermal sheet to achieve bar code printing, the thermal sheet is the core component of the printer. Since the thermal sheet is very sensitive and easily damaged, it needs to be protected by a protection cover.

[0003] However, at present, the protection cover structures of most thermal desktop bar code printers on the market still use the traditional screw fixing method for assembly. First of all, screw fixing requires tools, which increases the complexity of installation and disassembly and is extremely inconvenient to operate. Secondly, the screws are prone to loosening after long-term use, resulting in unstable fixing of the protection cover and reducing the protection effect on the thermal sheet. In addition, the screws of the protection cover fixed by screws are easily lost during the disassembly and assembly process, affecting the efficiency of re-assembly.

[0004] Therefore, a fixing structure for a thermal sheet protection cover of a thermal desktop bar code printer is needed to solve the above technical defects. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixing structure for a thermal sheet protection cover of a thermal desktop bar code printer to solve the problem of cumbersome screw installation mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing structure for a thermal sheet protection cover of a thermal desktop bar code printer, including an inner upper bin and a thermal sheet. The thermal sheet is installed in the inner upper bin. Inner fixing holes are provided inside the inner upper bin, and side fixing holes are provided on both sides of the inner wall of the inner upper bin. A protection cover is assembled above the inner upper bin. Two groups of bottom buckles are provided at the rear end of the protection cover, and side buckles are provided on both sides of the protection cover.

[0007] Preferably, the side buckles are matched with the positions of the side fixing holes, and the bottom buckles are matched with the positions of the inner fixing holes.

[0008] Preferably, the areas where the inner fixing holes and the side fixing holes are located are an inner groove, and the protection cover is embedded in the inner groove for combined assembly.
