Example 1

Referring to fig. 1-3, fig. 1 shows a schematic structure of a pull-resistant usb disk, where it can be seen that the pull-resistant usb disk is a split usb disk, and includes two main parts, namely a cap 100 and a usb disk main body 200. The main body 200 of the usb disk is generally flat and cuboid, and the cap 100 is generally semicircular and matched with the main body 200 of the usb disk.

The usb disk main body 200 includes a housing 210, a data interface 220 and a magnetic member 300 mounted on the housing 210. Specifically, the data interface 220 is on the same side of the housing 210 as the magnetic member 300. The inside of the cap 100 is hollow, and a slot communicating with the hollow is formed in the side of the cap 100, which is used for being in butt joint with the data plug-in port 220, the data plug-in port 220 is nested in the cap 100 through the slot, that is, the data plug-in port 220 and the cap 100 have an assembling relationship, the cap 100 may cover the data plug-in port 220 part of the usb disk main body 200, and the cap 100 may be separated from the usb disk main body 200, so that the two parts are in independent states of being not contacted with each other.

The cap 100 is further provided with a ferromagnetic member 400 opposite to the magnetic member 300. The magnetic member 300 magnetically engages the ferromagnetic member 400. The magnetic member 300 refers to a member made of a ferromagnetic material, and may be a magnet in general. The ferromagnetic member 400 refers to a member made of a ferromagnetic material, and is generally composed of Fe, co, ni elements and alloys thereof, rare earth elements and alloys thereof, and in the present utility model, the ferromagnetic member 400 may be an iron core.

The ferromagnetic piece 400 is disposed opposite to the magnetic piece 300, and when the slot of the cap 100 covers the data socket 220, the magnetic piece 300 is magnetically engaged with the ferromagnetic piece 400 to fix the relative positions of the usb disk main body 200 and the cap 100, so as to prevent the cap 100 from falling off, thereby protecting the data socket 220 more stably by the cap 100.

It should be noted that the existing split type USB disk mainly includes a USB disk main body and a cap, where the cap is clamped at a USB port on the USB disk main body and wraps the USB port. Because the USB flash disk main body and the cap are combined mainly through friction force between the USB flash disk main body and the cap, the action of inserting and pulling out the cap can cause certain abrasion to the cap and the USB flash disk main body, so that after a period of use, the cap is easy to cause that the cap cannot be tightly combined with the USB flash disk main body.

In the utility model, the pull-resistant USB flash disk couples the USB flash disk main body 200 and the cap 100 in a magnetic attraction matching mode, the coupling structure is relatively simpler, the problem of large coupling error caused by too many parts is avoided, and the relative position of the USB flash disk main body 200 and the cap 100 is not easy to deviate. In addition, the combination of the usb disk main body 200 and the cap 100 mainly depends on magnetic attraction, but not friction force between the two, so that the friction force between the two main body structures is smaller, and the friction force to be overcome in the plugging process of the cap 100 is also smaller, so that abrasion to the usb disk main body 200 and the cap 100 is not caused, the service life of the cap 100 is prolonged, and the protection effect of the cap 100 on the data plug interface 220 is enhanced.

Referring to fig. 2, fig. 2 shows a perspective view of the cap portion. In some embodiments, the ferromagnetic member 400 is a cylindrical iron core, and in other possible embodiments, the ferromagnetic member 400 may be a spherical iron core or a rectangular parallelepiped iron core. Accordingly, the shape of the ferromagnetic member 400 is not particularly limited.

In some preferred embodiments, only the magnet for forming the magnetic member 300 is provided on the usb disk main body 200, and the magnetic member 300 is not provided on the cap 100. It should be noted that, when the cap 100 is provided with a magnet, the magnet on the cap 100 is easily attracted to the data interface 220, which may cause the connection dislocation between the cap 100 and the usb disk main body 200. Thus in some preferred embodiments, magnets are provided only on the USB flash disk body 200.

Referring to fig. 2-3, in some embodiments, the magnetic elements 300 have two blocks, namely a first magnetic element 310 and a second magnetic element 320, and the first magnetic element 310 and the second magnetic element 320 are disposed on two sides of the usb disk main body 200. In contrast, a first ferromagnetic member 410 and a second ferromagnetic member 420 are disposed on opposite sides of the slot of the cap 100. The first ferromagnetic member 410 is disposed opposite to the first magnetic member 310, and the second ferromagnetic member 420 is disposed opposite to the second magnetic member 320. In the closing process of the cover cap 100 and the usb disk main body 200, the first ferromagnetic member 410 is magnetically attracted to the first magnetic member 310, and the second ferromagnetic member 420 is magnetically attracted to the second magnetic member 320, so as to increase the connection stability between the usb disk main body 200 and the cover cap 100.

In some embodiments, the main body of the ferromagnetic member 400 is fixed in the slot inside the cap 100, and only one end of the ferromagnetic member 400 that is attracted to the magnetic member 300 is exposed, so that the main body of the ferromagnetic member 400 cannot be directly observed by a user. Through the arrangement, the difference degree between the appearance of the pull-resistant USB flash disk and the existing USB flash disk is reduced, and the structural attractiveness of the pull-resistant USB flash disk is improved.

In some embodiments, the magnetic member 300 abuts the ferromagnetic member 400 when the U disk main body 200 is docked with the cap 100. It should be noted that, the attractive force between the magnetic member 300 and the ferromagnetic member 400 is a magnetic attraction force, and the magnetic attraction force is inversely proportional to the distance between the two. Therefore, when the magnetic member 300 abuts against the ferromagnetic member 400, the attraction force of the magnet between the magnetic member 300 and the ferromagnetic member 400 is maximized, so as to ensure the connection stability between the usb disk main body 200 and the cap 100.

Referring to fig. 3, in some embodiments, an annular engaging portion 600 is formed on the usb disk main body 200 around the data jack 220, and the engaging portion 600 is adapted to the slot in the cap 100. The engaging portion 600 is configured to be engaged into a slot in the cap 100 when the usb disk main body 200 is docked with the cap 100, so as to stably connect the cap 100 and the usb disk main body 200.

In some embodiments, a protrusion 800 is provided around the outer sidewall of the engaging portion 600. Specifically, the protruding portion 800 may be a strip-shaped protrusion, and the number of protruding portions 800 on the engaging portion 600 may be four. The four protrusions 800 are divided into two groups, and each group of protrusions 800 includes two protrusions 800. The two groups of protruding portions 800 are respectively located on the front and back sides of the engaging portion 600 (fig. 3 only shows the front side of the engaging portion 600, and a group of protruding portions 800 are also provided on the back side of the engaging portion 600 in the same manner as the group of protruding portions 800 located on the front side of the engaging portion 600), and the two protruding portions 800 located on the front side of the engaging portion 600 are separately located on opposite sides of the same end face on the engaging portion 600 at parallel intervals along the length direction of the usb disk main body 200. The protruding portion 800 is configured to abut against the inner side wall of the cap 100 when the engaging portion 600 is inserted into the slot, so as to increase friction between the usb disk main body 200 and the cap 100, and eliminate possible shaking after the cap 100 is closed.

Referring to fig. 3, in some embodiments, the U disc body 200 is provided with a magnetic member groove, and the magnetic member 300 is accommodated in the magnetic member groove. Specifically, the magnetic member groove is a cylindrical blind hole, and most of the cylindrical magnetic member 300 is embedded in the magnetic member groove, and only one end of the magnetic member 300 is exposed from the magnetic member groove and is flush with the end surface of the engaging portion 600 so as to attract the ferromagnetic member 400. With the above arrangement, the occupation space of the magnetic member 300 is reduced.

In some embodiments, the cap 100 is made of a non-ferromagnetic material. Specifically, the cap 100 may be made of an aluminum alloy material that is anodized. The purpose of this is to enable the magnetic member 300 to be accurately aligned with the ferromagnetic member 400 without interference. If the entire cap 100 is made of ferromagnetic material having strong magnetism, the magnetic member 300 may be attracted by other portions of the cap 100, so that the usb disk main body 200 cannot be accurately docked with the cap 100 in a predetermined position. In addition, the cap 100 subjected to the anodic oxidation treatment has good wear resistance and corrosion resistance.

In some possible embodiments, the housing 210 is made of a plastic material. In particular, the housing 210 may be a plastic housing 210. Since the plastic material is one of the flexible materials, by the above arrangement, the U-disk main body 200 can be made to have good impact resistance. In addition, the plastic housing 210 has lighter density, and the overall weight of the pull-out resistant USB flash disk can be reduced.

In some possible embodiments, the housing 210 is made of anodized aluminum alloy material to improve the wear and corrosion resistance of the housing 210.

In some embodiments, the data interface 220 is any one of a USB interface, mini USB interface (Mini USB interface), micro USB interface (Micro USB interface), type-C interface (USB-C interface).

Referring to fig. 3, in some embodiments, a hanging ring 500 is further provided on an outer sidewall of the usb disk main body 200, and the hanging ring 500 is used for a user to conveniently carry the pull-resistant usb disk. In other possible embodiments, a link chain connected to the usb disk main body 200 is inserted into the link 500.

Referring to fig. 3, in some embodiments, the usb body 200 is further provided with a heat dissipation hole 900, and the heat dissipation hole 900 is used for dissipating heat generated during operation of the usb body 200.

The utility model has the following specific working principle and beneficial effects:

when the pull-out-resistant USB flash disk is not used, the cap 100 is inserted onto the USB flash disk main body 200, so that the cap 100 covers the data insertion interface 220. At this time, the ferromagnetic member 400 abuts against the magnetic member 300, and the attractive force of the magnet between the ferromagnetic member 400 and the magnetic member ensures that the usb disk main body 200 and the cap 100 can be stably connected.

When the pull-resistant usb disk is required, the cap 100 is pulled out from the usb disk main body 200 to expose the data plug 220.

In the utility model, the USB flash disk main body 200 and the cap 100 are connected in a magnetic attraction matching mode, so that the connecting structure is simple, the problem of large combination error caused by excessive parts is avoided, and the relative position of the USB flash disk main body 200 and the cap 100 is not easy to deviate. In addition, the combination of the usb disk main body 200 and the cap 100 mainly depends on magnetic attraction, but not friction force between the two, so that the friction force between the two main body structures is smaller, and the friction force to be overcome in the plugging process of the cap 100 is also smaller, so that abrasion to the usb disk main body 200 and the cap 100 is not caused, the service life of the cap 100 is prolonged, and the protection effect of the cap 100 on the data plug interface 220 is enhanced.

Example IV

The present embodiment provides a pull-resistant usb flash disk, which is a further improvement made on the basis of the first embodiment, and the difference between the present embodiment and the first embodiment is that:
