In order to achieve the above-mentioned purpose of invention, the utility model adopts the following technical solutions:

A card reader with a rotatable USB plug, comprising a housing with an accommodating cavity, a circuit adapter board and a card reading slot, the circuit adapter board is fixed in the accommodating cavity of the housing, and the card reader The slot is electrically connected with the circuit adapter board, and a rotatable USB plug is provided at one end of the housing, and the USB plug is electrically connected with the circuit adapter board, and the insertion part of the USB plug extends out of the housing.

The tail of the USB plug is covered with a cylindrical pivot body, and a circular pivot hole that can be embedded with the pivot body is opened relative to the housing, and a rotatable gap is formed between the pivot body and the pivot hole. Clearance fit structure.

An annular slot is recessed on the pivot body, and an annular rib is convexly provided in the corresponding pivot hole, and the rib is buckled in the slot.

There is a stopper extending from the tail end of the pivot body, and correspondingly, there is a space for the stopper to move in the housing, and there is a protruding stop in the space that can push the stopper to control the rotation angle of the USB plug. piece.

The casing is composed of an upper casing and a lower casing.

The utility model also includes a U-shaped decorative plate, which is embedded in the recess provided on the outer wall of the casing.

The socket part of the USB plug is covered with a protective cap.

The card reading slot is an SD card expansion slot, an MMC card expansion slot, a CF card expansion slot, an SMC card expansion slot or an MS card expansion slot.

Compared with the prior art, the utility model has the beneficial effect that by setting the USB plug and the card reader shell as a pivot structure, after the card reader is plugged into the computer, the shell body of the card reader can be rotated to adjust the position of the shell body. location and orientation of the expansion card slot. Thereby effectively preventing the card reader from covering the USB socket next to it, and also providing convenience for the user to insert and remove the memory card.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Referring to Fig. 1 and Fig. 2, the specific structure of an embodiment of the present utility model is shown, as can be seen from the figure, the card reader comprises a hollow housing 20, and the front side of the housing 20 is provided with three slotted holes 201, 202, 203 , the left end is provided with a USB plug 10, the USB plug 10 is electrically connected with the circuit adapter board 30 in the accommodation cavity of the casing 20 through a wire 50; , and a cap 40 for protecting the USB plug 10 is set thereon.

The above-mentioned housing 20 is composed of an upper housing 21 and a lower housing 22. The outer surfaces of the upper housing 21 and the lower housing 22 are respectively provided with a concave position 21a, and the two concave positions are connected to form a U shape. , a corresponding U-shaped decorative plate 23 is embedded in the U-shaped recess 21a. After the upper shell 21 and the lower shell 22 are combined, a circular pivot hole 20 a is formed at the left end of the shell 20 .

An SD card expansion slot 31 and an MMC card expansion slot 32 are arranged side by side on the upper side of the above-mentioned circuit adapter board 30 , and an MS card expansion slot 33 is provided on the lower side. These three expansion slots correspond to the three slot holes 201, 202, 203 on the front side of the housing, which facilitates SD cards, MMC cards and MS cards to be inserted into their corresponding expansion slots.

3 to 6, in order to realize the rotation function of the USB plug 10, the utility model pivotally connects the USB plug 10 to the left end of the casing 20, that is, the tail of the USB plug 10 is covered with a cylindrical pivot body 10a, the pivot The connecting body 10a is nested into the pivoting hole 20a at the left end of the housing 20, and the pivoting body 10a and the pivoting hole 20a are in a rotatable clearance fit.

A ring-shaped rib 20b is protruded from the pivot hole 20a, and a ring-shaped slot 10b is correspondingly recessed on the pivot body. The ring-shaped rib 20b is inserted into the ring-shaped slot 10b, which can effectively limit USB The plug 10 comes out of the housing 20 .

In order to prevent the number of rotations of the USB plug 10 from being too many and causing damage to the electric cable 50, the present embodiment sets the rotating range of the USB plug 10 to 180 degrees. A block 10c is extended on the end surface of the body 10a, and a movable space 20d in which the block 10c can rotate is correspondingly provided in the casing, and the movable space communicates with the pivot hole 20a. The upper and lower housings 21, 22 are symmetrically provided with a limiting block 20c respectively, and the limiting block 20c extends into the aforementioned movable space 20d to push against the stopper 10c, and cooperates with the stopper 10c to control the USB plug. The effect of the rotation angle of 10 (see Fig. 5 and Fig. 6).

The key point of this utility model is that by setting the USB plug and the card reader housing as a pivotal structure, after the card reader is plugged into the computer, the card reader housing can be rotated to adjust the position of the housing and the orientation of the expansion card slot. . Thereby effectively preventing the card reader from covering the USB socket next to it, and also providing convenience for the user to insert and remove the memory card.

The above is only a preferred embodiment of a card reader with a rotatable USB plug in the utility model, and does not limit the technical scope of the utility model.
