Description
Technical Field
[0001] The utility model relates to the technical field of power adapters, and particularly relates to a power adapter which is convenient to carry. Background Art
[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. Generally, it consists of components such as a housing, a transformer, an inductor, a capacitor, a control IC, a PCB board, etc. Its working principle is to convert AC input into DC output. According to the connection method, it can be divided into wall-mounted type and desktop type. And the power adapter is also called an external power supply, which is a power supply voltage conversion device for small portable electronic devices and electronic appliances, and is commonly found in small electronic products such as mobile phones, liquid crystal displays, and laptop computers.
[0003] At present, most power adapters generally do not have a protection function. With use, information labels such as the rated power, input and output voltages on the power adapter will be affected by the environment and show wear, scratches, stains, etc., resulting in the labels being difficult to identify. If the labels are not clear, incorrect connection is likely to occur during use. Connecting the power adapter to an incompatible device will cause the device to malfunction, and may even damage the device or cause safety accidents such as fires and electric shocks. Moreover, if it accidentally falls or collides, it is easy to damage the housing of the power adapter, exposing the internal circuit and increasing the risk of electric shock. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a power adapter which is convenient to carry to solve the above-mentioned deficiencies in the technology.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A power adapter which is convenient to carry, including a power adapter body, and a first connecting wire and a second connecting wire are respectively plugged at both ends of the power adapter body.
[0006] Preferably, a protection structure is provided outside the power adapter body. The protection structure includes a first outer cover and a second outer cover covering the outside of the power adapter body. One end of the first outer cover close to the second outer cover is fixedly connected with a docking block, and a docking groove adapted to the docking block is opened at the end of the second outer cover close to the first outer cover. A heat dissipation structure is provided on the protection structure.
[0007] Preferably, fastening screws for firmly connecting the docking block and the docking groove are provided outside the first outer cover. Anti-slip blocks are fixedly connected at the corners of the outer surface walls of the first outer cover and the second outer cover. The anti-slip blocks can make the adapter have anti-slip property after being placed on the desktop, ensuring the stability of placement.
[0008] Through the above technical solution:
[0009] During use, dock and insert the docking block into the docking groove, and finally screw the fastening screw. In this way, the first outer cover and the second outer cover can be firmly covered outside the power adapter body, playing a protective role for the power adapter body, avoiding the situation that the information label on the power adapter is scratched and stained during use, resulting in difficult identification of the label, and preventing incorrect connection due to unclear label during use, which may cause the power adapter to be connected to an incompatible device, ensuring the normal operation of the device.
[0010] Preferably, a cover plate is hinged to the upper end of the storage groove. At the connection parts of the cover plate with the first outer cover and the second outer cover and inside the storage groove, there is a push lock (the push lock is a device used for locking or unlocking on some devices or articles, commonly used in suitcases, backpacks, kettle lids, etc., to ensure the safe closure of the articles. It belongs to the existing structure, so the relevant structures and principles are not described in the content).
[0011] Specifically, after the connection line is stored in the storage groove, cover the cover plate on the upper end of the storage groove through the push lock, which can play a role in blocking, avoiding impurities or dust from entering the storage groove. When taking out the connection line, press the cover plate to open the cover plate.
[0012] Preferably, a wire bundling structure is provided on the first outer cover and the second outer cover.

A first connection block is slidably connected to the inner surface wall of the empty slot. One end of the first connection block is hinged with a diamond-shaped telescopic frame. The end of the diamond-shaped telescopic frame away from the first connection block is hinged with a second connection block. The second connection block is slidably connected with the movable plate.
[0017] Through the above technical solution:
[0018] During use, the heat generated by the power adapter body in the outer cover is exported and dissipated through the heat dissipation slots opened in the movable plate, which can export and dissipate the heat generated when the power adapter in the outer cover is running, avoiding the phenomenon that the temperature in the outer cover is too high and affecting the normal use of the power adapter, facilitating the maintenance of the efficient operation of the power adapter, preventing performance degradation caused by overheating. In addition, it also effectively reduces the risk of fire occurrence and increases the safety during use. And in hot weather, pulling the movable plate to both sides, at this time the diamond-shaped telescopic frame is in a contracted state, opening the through slot. This operation can increase the surface area of heat export and air circulation, enhance the heat dissipation effect, and ensure that the adapter can provide stable power supply under different conditions.
[0019] In the above technical solution, the technical effects and advantages provided by the present utility model are:
[0020] 1. By setting the protection structure, the power adapter has a protection function, which can protect the power adapter body, avoiding the situation that the information labels such as the rated power, input and output voltages on the power adapter are affected by the environment and appear worn, scratched and stained during use, resulting in difficult-to-identify labels. Preventing unclear labels from easily causing incorrect connections during use, such as connecting the power adapter to incompatible devices, ensuring that the device can work normally, reducing the probability of equipment damage or accidents such as fire and electric shock. In addition, it also prevents the disadvantages that the outer shell of the power adapter is damaged due to accidental dropping or collision, resulting in the exposure of the internal circuit, reducing the risk of electric shock and improving the safety during use;
[0021] 2.
