Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a charger with multiple charging protocols and compatible with multiple devices. Background Art

[0002] With the rapid development of science and technology, electronic devices have become an important part of people's daily life. However, different electronic devices usually use different charging protocols, which requires users to carry multiple chargers when charging multiple devices, which not only increases the burden on users, but also causes waste of resources. Among them, the "charger compatible with multiple fast charging protocols and having a circuit measurement function" disclosed by announcement number "CN206775154U" has solved the various disadvantages of incompatibility. After further searching, it was found that the "charger compatible with multiple fast charging protocols" disclosed by announcement number "CN210137200U" The "charger that can charge multiple devices at the same time" has effectively solved the technical drawbacks of the existing charger that it is difficult to quickly fix on the desktop, causing the charger to move and the charging head to fall off, etc. through the specific technical structure setting. However, in actual use, there are still many defects in the charger with multiple charging protocols and multiple devices compatible with similar structures, such as: it is inconvenient to protect the plug of the charger. During the plugging and unplugging process, it is easy to contact with the metal sheet of the plug, resulting in safety hazards. At the same time, most chargers are not convenient to unplug, and they are easy to slip during unplugging, resulting in more effort when unplugging. Therefore, it is necessary to design a charger with multiple charging protocols and multiple devices compatible. Summary of the invention

[0003] The purpose of the utility model is to provide a charger that is compatible with multiple devices and has multiple charging protocols, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a charger compatible with multiple charging protocols and multiple devices, including a charger body, a fixing frame and a limiting ring, a protective cover movably installed on the top of the charger body, a movable frame movably installed on the front and rear ends of the charger body, a roller rotatably installed on the end of the movable frame, a fixing frame fixedly installed on the top of the movable frame, a limiting ring slidably installed on the bottom of the charger body, and a folding curtain fixedly connected between the limiting ring and the charger body.

[0005] By using a limiting ring to fit on the surface of the socket and using a folding curtain made of insulating material, the plug can be wrapped and protected. During the plugging and unplugging process, the plug will not be exposed, which can effectively avoid contact with the plug and avoid potential safety hazards. The safety effect during use is improved. By pressing the fixed frame downward, the movable frame can be driven to flip downward, and the charger body can be lifted up relatively easily, so that the charger body can be quickly pulled out.

[0006] Preferably, a magnet block is embedded and installed on the inner side of the protective cover, and a magnetic block corresponding to the magnet block is embedded and installed on the top of the charger body. When the protective cover is closed, the magnet block can correspond to the magnetic block, and the magnet block and the magnetic block can be adsorbed to each other, so that the protective cover can be easily fixed to avoid flipping.

[0007] Preferably, a USB socket is fixedly connected to the top of the charger body, and a Type-C socket and a Micro socket are fixedly installed on the top of the charger body on one side of the USB socket. It is convenient to charge devices with different data line interfaces, effectively improving the scope of application. At the same time, the charger body has multiple charging protocols built in, which can be conveniently compatible with multiple devices for charging operations.

[0008] Preferably, the movable frame is movably mounted on the charger body via a rotating shaft, and the outer side of the roller is wrapped with a rubber sleeve. The rotating shaft enables the movable frame to be flipped, and the rubber sleeve enables the roller to avoid scratching the surface of the socket plate when rolling.

[0009] Preferably, a pressing seat is fixedly installed on one side of the fixing frame, and the folding curtain is made of insulating material. By using the pressing seat to press down the fixing frame, the folding curtain is made of insulating material, thereby avoiding the situation of causing safety hazards.

[0010] Preferably, a plug extending from a limiting ring is fixedly mounted on the bottom of the charger body, and an insulating pad is adhered to the bottom of the limiting ring. By inserting the plug into the socket, it is convenient to connect the power supply, and the insulating pad can be used to conveniently isolate and insulate the limiting ring from the socket to avoid leakage.

[0011] Preferably, a movable column is fixedly installed on one side of the limit ring, and the movable column and the charger body are slidably installed via a sliding sleeve. The movable column can slide up and down along the sliding sleeve, which can facilitate the position of the limit ring and prevent the limit ring from deviating when moving up and down.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the cooperation between the limit ring and the folding curtain, the plug can be conveniently wrapped and protected by the folding curtain. During the plugging and unplugging process, the plug will not be exposed to the outside, which can effectively avoid contact with the plug, avoid safety hazards, and improve the safety effect during use.

[0014] By providing mutual cooperation among the fixed frame, the movable frame and the roller, the fixed frame can be pressed downward to cause the fixed frame to press the movable frame downward to rotate, and the roller can roll on the surface of the socket plate to easily lift up the charger body and quickly pull out the charger body, saving time and effort.
