Description

Technical Field

[0001] The present application relates to the technical field of USB flash drives, and in particular to a teaching USB flash drive protection kit. Background Art

[0002] U disk is the abbreviation of USB disk, which is also called "U disk" according to its homophony. U disk is a kind of flash memory, so it is sometimes called a flash disk. The biggest difference between U disk and hard disk is that it does not require a physical drive, plug and play, and its storage capacity far exceeds that of floppy disk, which is very easy to carry. U disk generally includes internal chipset, shell, USB plug connector and cover, etc. Usually, its shell is a straight hard structure. After the U disk is plugged in with the USB plug connector, it will protrude a distance from the computer. Because there are often consecutive classes during the teaching process, the U disk will not be unplugged during the break. Students moving around the host are prone to touch the U disk, which will cause damage to the U disk, affecting the teaching process and subsequent use, causing unnecessary trouble.

[0003] In the patent number: CN201927353U, a foldable USB flash drive, the USB interface is directly designed into a right-angle structure. The bending direction of this structure is fixed, and it cannot adapt to the plug-in mode in all directions. It is easy to conflict with the surrounding wire harness, resulting in the inability to plug in. In addition, the bent USB interface is directly exposed to the outside, which is not convenient for its protection. Therefore, in order to solve the above problems, this application provides a teaching USB flash drive protection kit.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that a USB flash drive may be easily damaged when directly plugged in and the applicability of the existing method of bending the USB interface is easily limited, the present application provides a teaching USB flash drive protection kit.

[0006] The present application provides a teaching USB flash drive protection kit, comprising a shell, a chip module installed inside the shell, and a USB plug connector for plugging, characterized in that: both sides of the front end of the shell are integrally formed with side panels, and the side panels are provided with a slide groove and a reversing groove, and elastic components are provided on both sides of the USB plug connector corresponding to the slide groove and the reversing groove, and the elastic components keep the USB plug connector horizontal in the slide groove and rotate in the reversing groove within a range of -135°-135°;

[0007] The USB plug connector is stored between the two side panels at the end of the slide slot.

[0008] Preferably, the reversing groove is a circular structure, and the diameter of the reversing groove is greater than the width of the sliding groove.

[0009] Preferably, the elastic component includes a sleeve and a slip ring that are slidably fitted with each other, and a resistance plate coupled to the slide groove and the reversing groove is fixedly connected to one side of the slip ring, and the resistance plate is elastically connected to the outer wall of the USB connector through a spring.

[0010] Preferably, the length of the collar and the abutment plate is smaller than the diameter of the commutation slot.

[0011] Preferably, a terminal is fixedly connected to the end of the USB plug connector, and the terminal is communicatively connected to the chip module via a wire row.

[0012] Preferably, notches are provided on both the upper and lower sides of the shell.

[0013] Preferably, push blocks are welded at both upper and lower ends of the USB plug connector, and the push blocks match the notches.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By arranging a side plate in front of the shell, and opening a slide groove and a reversing groove on the side plate, the USB plug connector uses elastic components on both sides to slide in the slide groove and the reversing groove to achieve storage, or to adjust the angle in the reversing groove. Compared with the existing technology, the scope of application is improved while improving the safety of the USB flash drive plugged into the host.

[0016] By designing the elastic component into a split-type collar, a contact plate, a sliding ring and a spring, the elasticity of the spring is used to increase the friction between the contact plate and the side plate, thereby improving the stability of the position of the USB connector in the reversing groove or the sliding groove, and avoiding unnecessary deflection of the housing under the action of gravity.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 - Figure 6 This application is described in further detail.

[0025] Embodiment 1:

[0026] Reference Figure 1 - Figure 6 A teaching U disk protection kit includes a shell 1, a chip module 6 installed inside the shell 1 and a USB plug connector 2 for plugging. Side panels 4 are integrally formed on both sides of the front end of the shell 1, and a slide groove 41 and a reversing groove 42 are opened on the side panels 4. The slide groove 41 is opened at the midline position of the side panels 4 to ensure that the USB plug connector 2 is in the middle position. Elastic components 7 are set on both sides of the USB plug connector 2 corresponding to the slide groove 41 and the reversing groove 42. The elastic component 7 keeps the USB plug connector 2 horizontal in the slide groove 41 and rotates in the reversing groove 42 within the range of -135°-135°.

[0027] The USB plug connector 2 is received between the two side panels 4 at the end of the slide slot 41 .

[0028] The reversing groove 42 is a circular structure, and the diameter of the reversing groove 42 is greater than the width of the slide groove 41. The elastic component 7 includes a sleeve ring 71 and a slip ring 73 that are slidably fitted with each other. One side of the slip ring 73 is fixedly connected with a contact plate 72 that is coupled to the slide groove 41 and the reversing groove 42, and the contact plate 72 is elastically connected to the outer wall of the USB plug connector 2 through a spring 74. The sleeve ring 71 and the slip ring 73 in the elastic component 7 can be rectangular or key groove-shaped structures, and their horizontal sections and the slide groove 41 are mutually contacted and limited to ensure that when the elastic component 7 is in the slide groove 41, the USB plug connector 2 is in a horizontal position. The spring 74 is used to push the two contact plates 72 on both sides toward the side plate 4, thereby increasing the friction between the contact plates 72 and the side plate 4, so as to ensure the stability of the USB plug 2 at different positions. The length of the ring 71 and the contact plate 72 is less than the diameter of the reversing groove 42. The length limit of the ring 71 and the contact plate 72 ensures that the elastic component 7 can rotate in the reversing groove 42 within the range of -135° to 135°. After rotation, the USB plug 2 is also kept relatively stable by the contact plate 72 and the inner wall of the reversing groove 42.

[0029] The end of the USB plug connector 2 is fixedly connected with a terminal 31, and the terminal 31 is communicatively connected with the chip module 6 through a wire row 5. The two ends of the wire row 5 are respectively welded to the terminal 31 and the chip module 6, and the length of the wire row 5 is greater than the displacement of the USB plug connector 2 to ensure a good connection relationship between them. A space for storing the wire row 5 is provided inside the housing 1.

[0030] Notches 111 are provided on both the upper and lower sides of the shell 1, and push blocks 3 are welded to the upper and lower ends of the USB plug connector 2, and the push blocks 3 and the notches 111 match each other, and the clearance between the push blocks 3 and the notches 111 matches each other, and the push blocks 3 are T-shaped when viewed from the side, and the top end of the push blocks 3 is arranged beyond the shell 1 for the user to control the USB plug connector 2.

[0031] When in use, the USB connector 2 is pushed to the side away from the shell 1 by the pushing block 3. After the elastic component 7 is pushed into the reversing groove 42, the USB connector 2 can be rotated at this time, and the USB connector 2 is inserted into the chassis jack. Then, the shell 1 is rotated to a position that fits the chassis shell 1, and the USB connection is completed. At this time, the U disk only protrudes a distance of the chassis USB connector 2, thereby reducing the probability of damage.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
