Description

Clamshell type USB device

The utility model relates to a USB device, in particular to a structure of a rotating clamshell fastening of a data product terminal (data card). Background technique

The existing USB device basically consists of a USB cap and a USB body having a lower case. There are basically two types of connection between the USB cap and the USB main body:

One is a separate type, that is, the USB cap is removed, and the cap is completely separated from the body without any connection, that is, the USB cap can be placed anywhere else. This type of connection is the most common, but there is a disadvantage that the USB cap is easily lost, which causes the metal USB head to lose protection, which causes inconvenience to the user.

Another type of connection is to remove the USB cap, which is connected to the body by a rope, such as a textile rope or a plastic rope. This connection method makes the user not have to consider the problem of the loss of the USB cap, which brings convenience to the user, but the disadvantage is that the rope is easy to be damaged or broken, or can not effectively solve the existence of the first method. The problem. Summary of the invention

The purpose of the utility model is to provide a rotating clamshell fastening structure, which can better solve the connection problem between the USB body and the USB cap of the USB device.

According to an aspect of the present invention, a flip type USB device is provided, including: a USB cap having a USB cap mounting hole;

a USB body having a USB body mounting hole;

A two-axis shaft that connects the USB cap and the USB body through a USB cap mounting hole and a USB body mounting hole. Compared with the prior art, the utility model has the following advantages:

1. The USB cap rotates around the two-axis shaft 180° to achieve the effect of flipping;

2. The structure is simple, the upper case of the USB device does not increase the cost, and the mounting hole is only added through the mold structure, and the USB cap is connected with the body, and the connection between them is firm, which can effectively solve the problem of the loss of the USB cap.

The groove 13 is located at a protruding portion of the USB cap 1, and the rib 23 is located at a recessed portion of the USB body 2.

On the locking mating side, the USB cap may further have a recessed portion, and the USB body has a protruding portion, and the protruding portion of the USB body is inserted into the recessed portion of the USB cap and the USB cap and the USB body are locked by the cooperation of the recess and the rib.

The rib of the USB device can also be engaged with the recess of the USB body on the USB cap for locking the USB cap and the USB body.

3 is a transverse cross-sectional view of a USB device according to an embodiment of the present invention. As shown in FIG. 3, the USB device includes a biaxial shaft side 5 and a locking mating side 4, and the USB cap 1 and the USB body 2 are on the biaxial shaft side. 5 is connected by the biaxial shaft 3, and the USB cap is opened or closed by the cooperation of the groove 13 and the rib 23 on the locking mating side 4.

4 is an exploded perspective view showing the assembly manner of the USB device according to the embodiment of the present invention. As shown in FIG. 4, on the side of the biaxial shaft, the USB cap 1 has a protruding portion, and the USB body 2 has a recessed portion, and the USB cap 1 is extended. The portion is inserted into the recess of the USB body 2 and the USB cap 1 and the USB body 2 are connected by a biaxial shaft 3. USB Cap 1. The upper case 2a and the lower case 2b of the USB body 2 have a cap mounting hole 11, a top case mounting hole 21, and a lower case mounting hole 22, both of which are located on the biaxial shaft side 5, respectively. The biaxial shaft 3 includes a cap rotating shaft 32 and a body rotating shaft 31 which are parallel to each other, and the cap rotating shaft 32 is a long shaft, and the body rotating shaft 31 includes two short shafts 31a and 31b connected to both ends of the cap rotating shaft 32, the cap rotating shaft 32 passes through the USB cap mounting hole 11, and among the two short shafts of the body shaft 32, 31a passes through the upper case mounting holes 2a, 31b of the USB body 2 through the lower case mounting hole 2b of the USB body (2).
