[0002] Removable printer covers are protective accessories specifically designed for printers. Their core function is to isolate external interference and extend the life of the device. The main body is often made of waterproof and dustproof PVC, Oxford cloth, or transparent acrylic, balancing protection with visibility of the device's status. Some high-end models also have an anti-static coating to prevent static electricity from damaging internal printer components. Structurally, they follow an "easy-to-install" design, commonly using Velcro, zippers, or snap-on opening methods. They can be quickly put on or taken off without disassembling the connecting cables, without affecting the printer's daily use and maintenance. They are suitable for a wide range of scenarios; when not in use, they prevent dust, moisture, and scratches; during movement and transport, they cushion collisions; and they prevent damage or safety hazards caused by pets scratching or children touching the device. They are practical protective tools for home and office printers.

[0003] Chinese Utility Model Patent Publication No. CN211054735U discloses a protective device for a printer. The specification of this printer protective device reveals that the suction cup and weight box enhance the stability of the printer, preventing displacement due to collisions and potential damage from falling to the ground. The water reservoir design cools the printer, protecting internal electrical components from overheating and extending its lifespan, reducing maintenance frequency, and saving costs. The upper and lower protective shells, locking buckles, and locking grooves work together to seal and protect the printer, providing good dust protection. However, this printer protective device lacks an installation structure for the protective cover itself, making it inconvenient to inspect or replace after prolonged use. Furthermore, the lack of a non-slip handle makes it prone to slippage when opening or closing the protective cover, resulting in poor practicality and hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a detachable protective cover mounting structure for printers. It can effectively solve the problems in the prior art, which does not have a mounting structure for the protective cover body, making it inconvenient to repair or replace it after long-term use, and does not have a non-slip structure for the handle, making it easy for the operator's hand to slip when opening or closing the protective cover body, resulting in poor practicality and difficulty in widespread use.

[0005] The technical solution adopted by this utility model is: a detachable protective cover mounting structure for a printer, including a printer body and a rotating plate. A protective cover body is disposed at the end of the rotating plate away from the printer body.

In use, the operator rotates rotating plate 2, which rotates the protective cover body 3, causing insert block 13 to insert into slot 17. When insert block 13 approaches slot 17, magnet 15 and magnet 19 attract each other, causing the protective cover body 3 to abut against stop block 16, achieving rapid closing of the protective cover body 3. This facilitates opening and closing of the protective cover body 3 and is highly practical. Due to the stability of the triangle, the design of reinforcing rod 12 prevents the rotating plate 2 from... Due to concentrated stress, bending, breakage, and other damage may occur. The structural strength and load-bearing capacity of the rotating plate 2 are greatly improved. The design of multiple protrusions 21 can significantly increase the friction between the handle 20 and the operator's hand. When the operator holds the handle 20 to open or close the protective cover body 3, it effectively prevents the hand from slipping, avoiding hand injuries or accidental drop and damage of the protective cover body 3. It is highly practical. The protective cover body 3, made of acrylic material, has excellent transparency. The operator can clearly observe the printing status inside the printer body 1, such as printing progress and paper remaining, without opening the protective cover body 3. This avoids frequent opening and closing of the protective cover body 3, which affects printing efficiency. At the same time, it can also detect printer body 1 malfunctions in time, which is convenient for quick handling. In addition, the protective cover body 3, made of acrylic material, has high hardness and good impact resistance, which can effectively resist minor external impacts and protect the internal components of the printer body 1 from damage.
