Description

Technical Field

[0001] This utility model relates to the field of mobile phone card tray technology, specifically to a mobile phone metal card tray structure that is anti-oxidation and self-cleaning. Background Technology

[0002] A SIM card tray is a tray part used to hold SIM cards. The main body of the tray is made of a combination of plastic and metal. Some models use a polymer composite material. When inserting or removing a SIM card, a small pin needs to be inserted into the pin hole on the outer end face of the tray and pushed in to eject the tray.

[0003] SIM card trays have poor insertion stability during use. Most SIM card trays use a pop-out structure, but the connection between the SIM card tray and the tray slot lacks a limiting structure. If the phone is dropped or subjected to significant vibration, the SIM card tray may pop out and be lost, thus affecting the stability of the SIM card tray. Moreover, after the SIM card tray is removed from the tray slot, it is prone to oxidation and dirt adhesion, affecting the sensitivity of the SIM card tray.

[0004] There is an urgent need for a mobile phone metal SIM card tray structure that is anti-oxidation and self-cleaning to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an anti-oxidation and self-cleaning metal SIM card tray structure for mobile phones, so as to solve the problem of poor SIM card tray insertion stability mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-oxidation self-cleaning metal SIM card tray structure for mobile phones, comprising a SIM card tray body, a SIM card tray end plate fixedly connected to the left side of the SIM card tray body, a SIM card tray pin hole provided on the SIM card tray end plate, a sealing ring sleeved at the connection between the SIM card tray end plate and the SIM card tray body, an interlocking groove provided inside the SIM card tray body, a limit plate fixedly connected to the rear end of the interlocking groove, a support baffle fixedly connected to the left side of the interlocking groove, an anti-slip plate fixedly connected to the left side of the front end of the SIM card tray body, an anti-slip ridge provided at the front end of the anti-slip plate, a SIM card slot provided on the right side of the front end of the SIM card tray body, a guide mark provided at the top end of the SIM card tray body, an anti-oxidation coating provided on the surface of the SIM card tray body, and a surface self-cleaning coating provided on the surface of the anti-oxidation coating.

[0007] As a further technical solution of this utility model, the card tray body adopts an alloy metal structure, the support baffle is located below the fitting groove, and the limiting card plate is located above the fitting groove.

[0008] As a further technical solution of this utility model, the guide sign is made of bright yellow, and a foolproof structure is provided on the right side of the front end of the card tray body.

[0009] As a further technical solution of this utility model, a reserved groove is provided on the side of the pin hole, and a sealing plug is fixedly connected inside the reserved groove, and the sealing plug is embedded inside the pin hole.

[0010] As a further technical solution of this utility model, the anti-oxidation coating is a nano-ceramic coating.

[0011] As a further technical solution of this utility model, the surface self-cleaning coating is a nano titanium dioxide coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-oxidation self-cleaning mobile phone metal card tray structure not only realizes the function of improving the stability of card tray use and the function of anti-oxidation self-cleaning, but also realizes the function of enhancing waterproof and dustproof effect; (1) By setting up a card tray body, a limiting card plate, a support baffle, an anti-slip plate, an anti-slip ridge, a guide mark and a foolproof structure, when the mobile phone card is placed inside the fitting groove of the card tray body, the limiting card plate and the support baffle can respectively limit and support the upper and lower parts of the mobile phone card, preventing the mobile phone card from falling out of the fitting groove. When installing the card tray body, the foolproof structure can prevent reverse installation. The guide mark on the card tray body can remind the user how to place the mobile phone card. The anti-slip plate and anti-slip ridge on the card tray body can fit the inside of the mobile phone card tray groove to achieve an anti-slip effect, preventing the card tray body from popping out and falling due to drops and vibrations. This structure realizes the functions of facilitating the use of the card tray and improving the stability of the card tray insertion. (2) By setting up a card tray body, a self-cleaning coating and an anti-oxidation coating, the card tray body adopts a metal alloy structure to improve strength and durability. An anti-oxidation coating is applied to the outside of the card tray body. The anti-oxidation coating uses a nano-ceramic coating to form a dense protective layer after high-temperature curing, which can achieve wear resistance and acid and alkali corrosion resistance. The surface self-cleaning coating outside the anti-oxidation coating adopts a titanium dioxide structure. Under ultraviolet irradiation, it decomposes organic matter and can clean fingerprints and oil stains, etc., and has antibacterial properties. This structure achieves the anti-oxidation and self-cleaning effect of the card tray through a double-layer protective structure. (3) By setting up a card pin hole, a card tray end plate, a sealing ring and a sealing plug, after the card tray body is inserted into the card tray slot of the mobile phone, the sealing plug can be inserted into the card pin hole on the card tray end plate. The sealing plug is fixedly connected to the card tray end plate and will not fall off or be lost. The sealing plug can also prevent external water and dust from entering the inside of the mobile phone card tray slot. The sealing ring at the card tray end plate can improve the waterproof sealing effect. This structure realizes the waterproof and dustproof effect of enhancing the connection between the card tray and the mobile phone. Attached Figure Description
