Technical Field

[0001] This utility model relates to the field of card readers, and more particularly to a card reader for portable terminal devices. Background Technology

[0002] USB card readers can read and transfer data stored on various types of cards, such as memory cards in cameras, mobile phones, or other devices. They are an important support device for daily data transmission. USB card readers are usually designed to be compact for easy carrying and use by users. As shown in the Chinese Patent Network, a card reader for portable terminal devices (publication announcement number CN217034744U) uses a cover-type sealing component to cover its USB interface, which provides good protection and high stability, making it suitable for use in the reading process of portable terminals.

[0003] However, the card readers mentioned in the above-disclosed patents and those currently available in the market still have some shortcomings: While existing methods of using a cover to protect the USB interface of the card reader provide good daily protection, they only offer basic dust protection, leaving the memory card interface exposed. Therefore, the protection provided by those skilled in the art is relatively limited and singular. To address these issues, a card reader for portable terminal devices is provided. Utility Model Content

[0006] As a further technical solution of this utility model: a first flip-up groove is provided at one end of the cover body of the cover, and the first flip-up groove is interference-fitted with the first cover after flipping and opening.

[0007] As a further technical solution of this utility model: a second flip-up groove is provided at the other end of the cover body, and the second flip-up groove is interference-fitted with the second cover after flipping and opening.

[0008] As a further technical solution of this utility model: the cover plate of the first cover is provided with a first protrusion, and the first protrusion is interference-fitted with one end opening of the cover.

[0009] As a further technical solution of this utility model: the cover plate of the second cover is provided with a second protrusion, and the second protrusion is interference-fitted with the other end opening of the cover.

[0010] As a further technical solution of this utility model: the end of the USB plug away from its interface is provided with a limiting flange, and both ends of the cover are provided with stop flanges.

[0011] As a further technical solution of this utility model: the two sides of the limiting protrusion are provided with guide grooves, and the two sides of the stop protrusion are provided with guide ribs that are mounted on the cover and slidably connected to the guide grooves.

[0012] As a further technical solution of this utility model: the USB plug has a first socket near its interface, and the USB plug has a second socket away from its interface.

[0013] This utility model provides a card reader for portable terminal devices, which has the following advantages compared with the prior art:

[0014] This card reader design utilizes a combination of a cover and a first cover to protect the memory card slot of the USB plug, and a combination of a cover and a second cover to protect the USB interface of the USB plug, forming an integrated protective cover structure. This provides comprehensive protection for the USB plug, offering better dust and dirt protection in daily use, as well as good compression resistance. It provides excellent internal protection for the USB plug, improving its safety, portability, and usability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-4 This utility model provides a technical solution for a card reader for portable terminal devices: A card reader for portable terminal devices includes a USB plug 6, a cover 1 located outside the USB plug 6 and sliding along the USB plug 6, a first cover 2 located at one end of the cover 1 away from the USB plug 6 interface, and a second cover 3 located at the other end of the cover 1 near the USB plug 6 interface. The first cover 2, when opened and closed, works in conjunction with the cover 1 to provide daily protection for the memory card slot on the USB plug 6, and the second cover 3, when opened and closed, works in conjunction with the cover 1 to provide daily protection for the USB port on the USB plug 6. In use, the first cover 2 and the second cover 3 are flipped open, and the USB plug 6 is pushed out from inside the cover 1. Specifically:

[0026] One end of the cover 1 has a first flip-up slot 4, which is press-fitted with the first cover 2 after flipping and opening. The other end of the cover 1 has a second flip-up slot 5, which is press-fitted with the second cover 3 after flipping and opening. When using the USB plug 6, the first cover 2 and the second cover 3 can be flipped and opened in sequence and snapped onto the corresponding first flip-up slot 4 and second flip-up slot 5, so that the opening structure of the cover 1 is unobstructed. At this time, since the first socket 61 is exposed, the corresponding memory card can be inserted. Then, by pushing the USB plug 6 out of the cover 1, the second socket 62 can be exposed, the corresponding memory card can be inserted, and the USB plug 6 is fully exposed, so that the USB interface can be inserted into the terminal device.

[0027] The cover plate of the first cover 2 has a first protrusion 21, and the first protrusion 21 is interference-fitted with one end opening of the cover 1. The cover plate of the second cover 3 has a second protrusion 31, and the second protrusion 31 is interference-fitted with the other end opening of the cover 1. After the USB plug 6 is used up, when the USB plug 6 is pushed back into the cover 1, the first cover 2 and the second cover 3 are flipped in sequence, and the first protrusion 21 and the second protrusion 31 on the two sets of covers are sequentially snapped onto the two openings of the cover 1 to form a closed cover structure, which provides all-round cover protection for the USB interface and memory card slot of the USB plug 6, so as to improve safety and portability.

[0028] Example 2

[0029] Please see Figure 5-7 This embodiment further explains Example 1. The end of the USB plug 6 away from its interface is provided with a limiting flange 7, and both ends of the cover 1 are provided with stop flanges 8. When the cover 1 is pushed along the USB plug 6, the contact between the stop flange 8 and the limiting flange 7 plays a stopping and limiting role, limiting the extension and retraction of the cover 1 and preventing the cover 1 from sliding out of the USB plug 6.

[0030] As a further embodiment, guide grooves 71 are provided on both sides of the limiting protrusion 7, and guide ribs 81 are provided on both sides of the stop protrusion 8, which are mounted on the cover 1 and slidably connected to the guide grooves 71. By setting the sliding combination of guide grooves 71 and guide ribs 81, the sliding stability of the cover 1 along the USB plug 6 is improved, and it can also play the role of support ribs to improve the protective stability of the cover of the USB plug 6.

[0031] Example 3

[0032] Please see Figure 7This embodiment further illustrates other embodiments: the USB plug 6 has a first socket 61 near its interface and a second socket 62 away from its interface. By setting the combination of the first socket 61 and the second socket 62 on the USB plug 6, the first socket 61 can be a smaller model, such as a mobile phone memory card interface, and the second socket 62 can be a larger model, such as an SD memory card interface, so as to improve the multi-functional performance of the USB plug 6.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
