[0001] The utility model relates to the technical field of power adapters, in particular to a protective structure of a power adapter. Background Art
[0002] A power adapter is a device used to power electronic devices. It usually has two pins for connecting to the mains, and also has a USB connector for connecting the power cord. When the power adapter is in use, the two pins are inserted into the sockets on the socket, and then one end of the USB power cord is connected to the USB connector and the other end is connected to the electronic device, so that the electronic device can be powered.
[0003] Most of the existing power adapters do not have a protective structure. In order to facilitate the use of the power adapter, the pins of the power adapter are directly exposed to the outside, which makes it easy for the pins to be bent by external forces, making it inconvenient to use normally and reducing the service life of the power adapter.
[0004] Therefore, we propose a protection structure of a power adapter to solve the above problems. Utility Model Content
[0005] The utility model provides a protective structure for a power adapter, which solves the problem that most of the existing power adapters mentioned in the above background technology have no protective structure. In order to facilitate the use of the power adapter, the pins of the power adapter are directly exposed to the outside, which makes it easy for the pins to be bent by external forces, which makes it inconvenient to use normally and reduces the service life of the power adapter.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 - Figure 3 A protective structure of a power adapter comprises a protective shell 1 and a power protector body 2 slidably mounted inside the protective shell 1, card slots 17 are provided on both sides of the protective shell 1, movable components 18 are installed in the card slots 17, limiting components 3 are installed on both side walls of the power protector body 2, a slide slot 11 is provided on the side wall of the protective shell 1, a telescopic plate 12 is fixedly installed on the side wall of the slide slot 11, a push block 13 is fixedly installed at one end of the telescopic plate 12, one side of the push block 13 is fixedly connected to the upper wall of the power protector body 2, two openings 14 are provided on one side of the protective shell 1, waterproof components 16 are installed in the two openings 14, two pins 21 are fixedly installed on one side of the power protector body 2, and the two pins 21 can be slidably connected in the two openings 14 respectively.
[0023] When the power protector body 2 is not in use, the power protector body 2 is stored inside the protective shell 1. When the power protector body 2 is needed, the movable components 18 on both sides can be pushed inward. At this time, the limit component 3 releases the limit on the power protector body 2, and the push block 13 can be pushed along the slide groove 11. When the push block 13 moves, it drives the power protector body 2 to slide inside the protective shell 1. When the power protector body 2 is pushed to the maximum movable distance, the power protector body 2 is fixed again with the cooperation of the limit component 3 and the card slot 17. At this time, the pin 21 slides into the opening 14, and the waterproof component 16 is opened by the pin 21. At this time, the power protector body 2 can be used directly. When the device is not in use, the power protector body 2 can be stored inside the protective shell 1 to protect the pin 21.
[0024] See also Figure 2 - Figure 5 The movable component 18 includes a limit plate 181 fixedly installed on both sides of the inner wall of the slot 17, and a movable block 182 is slidably connected to the two limit plates 181. With the cooperation between the slot 17, the limit plate 181 and the movable block 182, the movable block 182 can slide in the slot 17.
[0025] The limiting assembly 3 includes a fixed block 31 fixedly mounted on the side wall of the power protector body 2, a chamber 32 is provided inside the fixed block 31, a slider 33 is slidably connected inside the chamber 32, and the slider 33 can slide inside the fixed block 31 under the cooperation between the fixed block 31, the chamber 32 and the slider 33.
[0026] A spring 34 is fixedly installed between the side wall of the slider 33 and the inner wall of the chamber 32. The slider 33 can be slidably connected in the slot 17. Under the cooperation between the slider 33, the chamber 32, the spring 34 and the slot 17, the spring 34 can automatically push the slider 33 outward.
[0027] The upper and lower ends of the opening 14 are both provided with slots 15. The waterproof component 16 includes a slider 161 slidably connected in the slot 15. A spring 162 is fixedly installed between the side wall of the slider 161 and the inner wall of the slot 15. With the cooperation between the opening 14, the slot 15, the slider 161 and the spring 162, the two sliders 161 can block the opening 14 to prevent water from flowing into the interior of the protective shell 1.
[0028] The two sliders 161 are in contact with each other, and the inner side of the contact surface of the two sliders 161 is an arc surface 163. With the cooperation between the sliders 161 and the arc surface 163, the pin 21 can push the two sliders 161 upward and downward through the arc surface 163 when moving.
[0029] When the power protector body 2 needs to be used, the movable blocks 182 on both sides can be pushed inward at the same time. The movable blocks 182 slide along the limit plate 181 and push the slider 1 33 into the interior of the chamber 32. At this time, the power protector body 2 can be driven to slide inside the protective shell 1 by the push block 13 at the upper end. When sliding to a certain distance, the slider 1 33 slides to the position of another card slot 17. At this time, the slider 1 33 is automatically pushed outward by the spring 1 34 and slides inside the card slot 17 to complete the fixation of the power protector body 2. During the sliding process, the pin 31 slides into the inside of the opening 14, and in the process of continuing to push, the pin 31 contacts the arc surface 163, squeezing the slider 2 161 up and down. When the power protector body 2 is fixed, the pin 31 also slides to extend out of the opening 14. At this time, the device can be used. When the device is not in use, the waterproof component 16 can prevent water from entering the interior of the protective shell 1. The power protector body 2 can be limited and stored through a simple structure, which is easy to operate.
