Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please refer to Figure 1-6 ;

[0023] Currently, some USB cover self-locking switches have complex designs, and the self-locking mechanism is easily damaged when subjected to external forces, such as snap-fit ​​breakage. Repeated insertion and removal may cause metal fatigue or wear on plastic components, leading to decreased reliability and poor quality of the locking function. Frequent replacement of new USB cover self-locking switches increases costs and is inconvenient to operate.

[0024] This utility model discloses a positioning structure for a USB cover, including a USB cover 1 and an output panel 2. The USB cover 1 and the output panel 2 are rotatably connected. The output panel 2 is provided with a USB cover fixing bracket 3, and the output panel 2 is connected to the USB cover fixing bracket 3. A through groove 4 is provided at the upper end of the USB cover 1. A rotating shaft 5 extends from the two side walls of the through groove 4. A protrusion 6 and a protrusion 7 are fixedly provided on the rotating shaft 5. The USB cover fixing bracket 3 is provided with an elastic part 8. The elastic part 8 and the USB cover fixing bracket 3 are provided with a positioning groove 9. Both the protrusion 6 and the protrusion 7 can be engaged with the positioning groove 9. When the protrusion 6 is engaged with the positioning groove 9, the USB cover 1 and the output panel 2 are in contact. When the protrusion 7 is engaged with the positioning groove 9, the angle between the USB cover 1 and the output panel 2 is ∠A, and the degree of ∠A is 0°-180°.

[0025] Specifically, the USB cover fixing bracket 3 is mounted on the output panel 2. The rotating shaft 5 is rotatably connected to the USB cover fixing bracket 3. In the initial state, the protrusion 6 is engaged with the positioning groove 9, and the USB cover 1 is in contact with the output panel 2. At this time, the USB cover 1 can protect the USB port from dust. It is worth noting that the elastic part 8 is flexible, so that when the protrusion 6 is subjected to external force, the protrusion 6 will disengage from the positioning groove 9. When the user needs to insert a USB flash drive or other parts into the USB port, the user first applies external force to rotate the USB cover 1. Under the action of external force, because the elastic part 8 is flexible, the protrusion 6 disengages from the positioning groove 9, and then rotates with the USB cover 1 relative to the output panel 2. That is, the rotating shaft 5 rotates with the output panel 2, and then the protrusion 7 rotates with the rotating shaft 5. When the second protrusion 7 of USB cover 1 engages with the positioning groove 9, the USB cover 1 is fixed relative to the output panel 2. At this time, the angle between the USB cover 1 and the output panel 2 is ∠A, and the degree of ∠A is preferably 120°. Since the USB cover 1 is fixed relative to the output panel 2, the user can more conveniently insert a USB flash drive or other parts into the USB port. In the initial state, the first protrusion 6 engages with the positioning groove 9, and the USB cover 1 fits against the output panel 2, effectively protecting the USB interface from dust and foreign objects. When an external force is applied to rotate the USB cover 1, the flexible design of the elastic part 8 causes the first protrusion 6 to disengage from the positioning groove 9, and the second protrusion 7 then engages with the positioning groove 9, fixing the USB cover 1 at an angle of 0°-180°, preferably 120°, with respect to the output panel 2, making it convenient for the user to insert a USB flash drive or other parts. This structure simplifies the self-locking design, reducing problems such as buckle breakage, metal fatigue, or plastic wear caused by external force or frequent insertion and removal in traditional complex self-locking switches. It improves locking reliability and service life, while reducing maintenance costs and operational complexity, enhancing user convenience and equipment durability.

[0026] Furthermore, the USB cover fixing bracket 3 includes a fixing rib 31 and an elastic rib 32. The fixing rib 31 is set vertically, and the elastic rib 32 is set horizontally. The fixing rib 31 and the elastic rib 32 are fixedly connected. Protrusion 1 6 and protrusion 2 7 are both located at one end of the rotating shaft 5. The other end of the rotating shaft 5 contacts the groove wall of the semi-circular groove of the fixing rib 31 and rotates relative to each other. The positioning groove 9 is located at one end of the elastic rib, and the groove opening of the positioning groove 9 faces upward.

[0027] Specifically, the reliability of positioning and rotation is further optimized by the fixing ribs 31 and elastic ribs 32 set in the USB cover fixing bracket 3. The fixing rib 31 is set vertically, and its semi-circular groove contacts the rotating shaft 5 to ensure the stable rotation of the rotating shaft 5. The elastic rib 32 is set horizontally and supports the positioning groove 9. Through its elastic properties, it realizes the smooth engagement and disengagement of the first protrusion 6 and the second protrusion 7. The upward-facing design of the positioning groove 9 facilitates the precise engagement of the first protrusion 6 and the second protrusion 7, enhances the fixing effect of the USB cover 1 in the closed or open state, effectively reduces the risk of damage caused by external pressure or frequent operation, and improves the durability and stability of the self-locking structure.

[0028] In this embodiment, the USB cover fixing bracket 3 is inserted into the output panel 2. The output panel 2 has an insertion hole. The fixing ribs 31 and elastic ribs 32 of the USB cover fixing bracket 3 pass through the insertion hole. A number of positioning posts 10 are provided on the side of the output panel 2 away from the USB cover 1. A number of positioning cylinders 11 are provided on the USB frame. The positioning posts 10 and positioning cylinders 11 are fixed by screws. Furthermore, the output panel 2 extends an upper shielding part 12 and two side shielding parts 13 corresponding to the position of the insertion hole. Both side shielding parts 13 have a clearance hole 14. The clearance hole 14 is used to avoid the rotating shaft 5. A front shielding part 15 is fixedly provided on the upper shielding part 12. The front shielding part 15 is flush with the plane of the USB cover 1. Furthermore, the output panel 2 has a limiting ring groove 16. The USB cover 1 is engaged with the limiting ring groove 16.
