It can also be used with USB-to-other-interface adapters to achieve connections between devices with different interfaces.

[0003] Existing USB protective cases are generally made of metal materials such as aluminum alloy and stainless steel. Metal protective cases have excellent strength and durability, providing high-strength protection for USB devices and effectively preventing severe impacts and compression. However, USB protective cases cannot be quickly installed or removed, which means that when using them on different computers, users need to spend a lot of time installing or removing the protective case, greatly reducing work efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of an easy-to-install and disassemble USB protective case buckle structure, including an interface body 1, a first sliding post 2 slidably connected to the inner wall of the interface body 1, a stop block 3 fixedly connected to the outer wall of the first sliding post 2, the outer wall of the stop block 3 adhering to the outer wall of the interface body 1, a locking tooth 4 fixedly connected to the outer wall of the first sliding post 2, a first spring 5 provided on the outer wall of the first sliding post 2, the outer wall of the first spring 5 being provided on the outer wall of the locking tooth 4, the outer wall of the first spring 5 being provided on the outer wall of the interface body 1, a sliding component provided on the outer wall of the locking tooth 4, a base 12 fixedly connected to the lower surface of the sliding component, a fixing block 8 fixedly connected to the outer wall of the sliding component, the outer wall of the locking tooth 4 being provided on the outer wall of the fixing block 8, a support post 10 fixedly connected to the upper surface of the base 12, a support component provided on the inner wall of the support post 10, and the upper surface of the support component adhering to the lower surface of the interface body 1;

[0027] Specifically, the downward pressing of the interface body 1 causes the locking teeth 4 to slide on the outer wall of the sliding component. When the locking teeth 4 slides, they cooperate with the interface body 1 to compress the first spring 5. When the locking teeth 4 slides on the outer wall of the sliding component, they drive the sliding component to move. When the sliding component contacts the fixed block 8, the locking teeth 4 will slide on the outer wall of the fixed block 8. At this time, the support component will pop out the interface body 1. Through the cooperation of the sliding component and the support component, the effect of quickly installing and removing the interface body 1 can be achieved.

[0028] Reference Figures 2-4 The sliding assembly includes a fixed post 6, the outer wall of the locking tooth 4 is slidably connected to the outer wall of the fixed post 6, a sliding block 7 is slidably connected to the outer wall of the fixed post 6, the outer wall of the locking tooth 4 is disposed on the outer wall of the sliding block 7, the lower surface of the fixed post 6 is fixedly connected to the upper surface of the base 12, and the outer wall of the fixed post 6 is fixedly connected to the inner wall of the fixed block 8; the support assembly includes a second spring 11, the outer wall of the second spring 11 is disposed on the inner wall of the support post 10, a second sliding post 9 is disposed on the outer wall of the second spring 11, the outer wall of the second sliding post 9 is slidably connected to the inner wall of the support post 10, and the upper surface of the second sliding post 9 is attached to the lower surface of the interface body 1;

[0029] Specifically, the base 12 is used to support the fixed column 6, the fixed column 6 is used to limit the running trajectory of the sliding block 7, and when the sliding block 7 and the fixed block 8 come into contact, they will form a complete sphere, thereby allowing the locking tooth 4 to slide out. The second sliding column 9 and the second spring 11 cooperate with each other to pop out the interface body 1.

[0030] Reference Figure 1 , Figure 5 and Figure 6The inner wall of the interface body 1 is slidably connected to a limiting post 14, the outer wall of the limiting post 14 is fixedly connected to a waterproof layer 17, the outer wall of the waterproof layer 17 is fixedly connected to a silicone layer 16, the outer wall of the silicone layer 16 is fixedly connected to a wear-resistant layer 13, and the outer wall of the waterproof layer 17 is attached to the outer wall of the interface body 1; the inner wall of the interface body 1 has a hole 15, through which the limiting post 14 is slidably connected to the inner wall of the interface body 1; the wear-resistant layer 13 is made of aramid fiber and resin; the silicone layer 16 is made of silicone rubber; and the waterproof layer 17 is made of polypropylene and polyurethane.

[0031] Specifically, since aramid fiber and resin are both high-strength wear-resistant materials, they can improve the overall wear resistance of the wear-resistant layer 13. Silicone rubber has excellent toughness and resilience, which can improve the overall resilience of the silicone layer 16 and prevent the wear-resistant layer 13 and the waterproof layer 17 from breaking due to external forces. Since polypropylene and polyurethane are both excellent waterproof materials, they can improve the overall waterproof effect of the waterproof layer 17 and prevent external moisture from entering the wiring port and causing a short circuit. Through the cooperation between the wear-resistant layer 13, the silicone layer 16 and the waterproof layer 17, the wiring port is protected and its service life is extended.

[0032] Working principle: First, the interface body 1 is pressed down, causing the locking teeth 4 to slide on the outer wall of the fixed post 6 and the sliding block 7. When the locking teeth 4 slides on the outer wall of the sliding block 7, they cooperate with the interface body 1 to compress the first spring 5. At this time, the interface body 1 is lifted up, causing the locking teeth 4 to move the sliding block 7 upward synchronously. When the sliding block 7 and the fixed block 8 are in contact to form a complete sphere, the locking teeth 4 will slide on the outer wall of the fixed block 8. The second sliding post 9, the support post 10 and the second spring 11 cooperate to pop out the interface body 1. By sliding the locking teeth 4 on the outer wall of the fixed block 8, the interface body 1 can be quickly disassembled or installed, thereby improving the efficiency of the interface body 1.

[0033] Since the wear-resistant layer 13 is made of aramid fiber and resin, both of which are high-strength wear-resistant materials, it can improve the overall wear resistance of the wear-resistant layer 13. Silicone rubber has excellent toughness and resilience, which can improve the overall resilience of the silicone layer 16. Since the waterproof layer 17 is made of polypropylene and polyurethane, both of which are excellent waterproof materials, it can improve the overall waterproof performance of the waterproof layer 17. Through the cooperation between the wear-resistant layer 13, the silicone layer 16 and the waterproof layer 17, the connection port can be effectively protected, avoiding damage to the connection port due to corrosion from the outside air, and extending the service life of the connection port.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
