Description

Technical Field

[0001] This application belongs to the technical field of cash register accessories, specifically a protective cover for the control panel of a supermarket cash register. Background Technology

[0002] In the daily operations of a supermarket, the cash register is the core equipment for completing transactions, and the stable operation of its control panel directly affects checkout efficiency and transaction accuracy. The large number of customer checkout operations daily means the control panel is under frequent use. Staff need to frequently press buttons or touch the screen to complete operations such as scanning and entering amounts, while customers may also accidentally touch the panel while waiting. This high-intensity, high-frequency contact easily leads to wear and scratches on the panel surface, affecting not only the tactile feel and sensitivity during operation but also potentially causing misreading of information due to damage to the display area, thus interfering with the normal checkout process.

[0003] Besides wear and tear caused by human operation, environmental factors also significantly impact the control panel of the cash register. Supermarkets experience high foot traffic, and dust and debris floating in the air constantly accumulate on the panel surface. Over time, this not only affects the appearance of the equipment but can also enter the machine through button gaps or interfaces, causing problems such as poor circuit contact and component aging. Furthermore, liquid spills are inevitable in the checkout area, such as accidentally knocked-over drinks or water spilled during cleaning. If these seep into the control panel, they can easily cause short circuits, leading to cash register shutdowns and unnecessary losses for supermarket operations.

[0004] However, the existing protective covers are cumbersome to install and remove, which is not conducive to daily maintenance. They also have poor fit, are easy to loosen and shift, and have limited protective effect. Utility Model Content

[0005] The purpose of this application is to provide a protective cover for the control panel of a supermarket cash register, in order to solve the problems mentioned above, such as the cumbersome installation and disassembly of existing protective covers, which are not conducive to daily maintenance, have poor fit, are easy to loosen and shift, and have limited protective effect.

[0006] The technical solution adopted in this application is as follows: A protective cover for a supermarket cash register control panel includes a support base, a support rod is provided on the upper surface of the support base, a control panel is installed on the upper end of the support rod, a connecting piece is slidably connected to the upper and lower ends of the control panel, a protective cover frame is provided between the connecting pieces, an installation frame is provided on one side of the protective cover frame, an elastic membrane corresponding to the control panel is provided inside the installation frame, fixing screws are provided at the four corners of the installation frame, fixing holes corresponding to the fixing screws are opened at the four corners of the protective cover frame, and a fixing nut is threaded to one end of the fixing screw.

[0007] By adopting the above technical solution, the protective cover frame can be fixed to the surface of the control panel under the action of the connecting piece, thus protecting it and improving its protective performance. At the same time, the connecting piece slides at the top and bottom of the control panel, making it easy to remove the protective cover frame and improving convenience.

[0008] In a preferred embodiment, a sealing gasket corresponding to the control panel is affixed to one side surface of the mounting frame.

[0009] By adopting the above technical solution, the friction between the mounting frame and the control panel is increased under the action of the sealing gasket, thereby improving the stability of their connection. At the same time, the control panel is also sealed to prevent dust from entering the surface of the control panel from the gap between the control panel and the mounting frame, thus improving the sealing and dustproof performance.

[0010] In a preferred embodiment, a magnetic block one is installed on one inner wall of the connecting piece, and magnetic blocks two corresponding to the magnetic block one are installed on the upper and lower sides of the control panel.

[0011] By adopting the above technical solution, the magnetic attraction between magnetic block one and magnetic block two can ensure the stability of the connection between the connecting piece and the control panel, making it less prone to shaking during use. It also facilitates the disassembly and assembly of the connecting piece, improving convenience.

[0012] In a preferred embodiment, the elastic membrane is made of high-temperature vulcanized food-grade silicone.

[0013] By adopting the above technical solution, it has good mechanical properties, heat resistance and aging resistance, and can remain stable in the daily temperature environment of supermarkets. It is not easy for its performance to decline due to temperature changes. At the same time, its texture is tough and has excellent elasticity. When it is covered on the surface of the control panel, it can fit closely to the touch area to ensure the sensitivity of operation. Even if it is pressed frequently for a long time, it can quickly rebound and is not easily deformed.

[0014] In a preferred embodiment, the protective cover frame is made of transparent high-strength polycarbonate.

[0015] By adopting the above technical solution, it has good impact resistance, which can effectively resist external collisions and impacts, and prevent the control panel from being damaged by accidental impacts. At the same time, it has good wear resistance, which can reduce scratches caused by friction during daily use, keep the surface of the protective cover smooth and flat, and extend its service life.

[0016] In a preferred embodiment, the surface of the protective cover frame is coated with a nano-silica coating.

[0017] By adopting the above technical solution, it has excellent hydrophobicity and antifouling properties. Its surface energy is extremely low, making it difficult for dust to adhere to it, reducing dust accumulation and cleaning frequency. At the same time, it has strong adhesion to polycarbonate materials, is not easy to fall off, and can maintain the effect of preventing dust adhesion for a long time.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In this application, the connecting piece allows the protective cover frame to be fixed to the surface of the control panel for protection, thus improving its protective properties. At the same time, the connecting piece slides at the top and bottom of the control panel, making it easy to remove the protective cover frame and improving convenience. Attached Figure Description
