Description

Technical Field

[0001] The utility model relates to the technical field of DC adapter plugs, in particular to a DC adapter plug that improves the convenience and safety of use. Background Technique

[0002] With the rapid development of the social economy, almost every family will purchase an electric vehicle for travel. An electric vehicle, that is, an electric drive vehicle, also known as an electric car, is divided into an AC electric vehicle and a DC electric vehicle. Generally speaking, an electric vehicle uses a battery as an energy source, and through components such as a controller and a motor, it converts electrical energy into mechanical energy to move, and controls the vehicle speed by changing the magnitude of the current. When the battery runs out, it needs to be charged. Moreover, there are many brands of electric vehicles, and a DC adapter plug is required. However, for an existing DC adapter plug that improves the convenience and safety of use, its end is exposed during storage or carrying, resulting in easy damage to the plug part, which may cause problems such as poor contact during use and affect the use. Therefore, we introduce a new DC adapter plug that improves the convenience and safety of use. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a DC adapter plug that improves the convenience and safety of use, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A DC adapter plug that improves the convenience and safety of use includes an adapter. Fixed seats are arranged at the front parts of the left end and the right end of the adapter. Installation grooves are arranged at the front ends of the two fixed seats. Card slots are arranged on the inner walls of the two installation grooves. A sealing groove is arranged at the front end of the adapter. A first protection device is arranged at the front end of the adapter. A first connecting wire is arranged in the middle of the rear end of the adapter. A spiral telescopic wire is arranged at the rear end of the first connecting wire. A second connecting wire is arranged at the rear end of the spiral telescopic wire. A DC plug is arranged at the rear end of the second connecting wire. A second protection device is arranged at the rear part of the outer surface of the DC plug.

[0006] Preferably, the first protection device includes a protective cover. Sealing gaskets are arranged around the rear end of the protective cover. A storage groove is arranged at the front end of the protective cover. A pull ring is movably installed in the storage groove through a movable shaft. Installation blocks are arranged at the left end and the right end of the protective cover. Springs are fixedly installed in the inner grooves of the two installation blocks. Sliders are movably installed in the inner grooves of the two installation blocks. Convex blocks are fixedly installed at the ends of the two sliders away from the springs.

[0007] Preferably, the protective cover is movably clamped to the sealing groove and the mounting groove through a sealing gasket and a mounting block.

[0008] Preferably, the bump is movably clamped in the clamping groove through a spring.

[0009] Preferably, the second protection device includes a cylindrical sleeve and a fixing ring. A plurality of anti-slip protrusions are arranged on the outer surface of the cylindrical sleeve. An annular magnetic attraction buckle is arranged at the front end of the cylindrical sleeve. An annular magnetic attraction groove is arranged at the rear end of the fixing ring.

[0010] Preferably, the fixing ring is fixedly installed on the front part of the outer surface of the DC plug. The cylindrical sleeve is movably clamped in the annular magnetic attraction groove through the annular magnetic attraction buckle.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By aligning the protective cover with the adapter, the two mounting blocks are respectively aligned with the two mounting grooves and installed therein. The elastic contraction and elastic reset of the two springs cause the two bumps to be respectively clamped in the two clamping grooves. At the same time, the sealing gasket is also clamped in the sealing groove, so as to protect the adapter. By sleeving the cylindrical sleeve on the outer surface of the DC plug and making the annular magnetic attraction buckle clamped in the annular magnetic attraction groove, the DC plug can be protected, avoiding the problem that the plug part is damaged during carrying or storage, which affects the use.

[0013] 2. By squeezing the two bumps, the two bumps are separated from the two clamping grooves. At the same time, by pulling the pull ring, the sealing gasket is separated from the sealing groove, and the protective cover can be removed. By holding and pulling the cylindrical sleeve by hand, the annular magnetic attraction buckle is separated from the annular magnetic attraction groove, so that the DC plug is opened, and charging can be conveniently used. When charging, the spiral telescopic wire can be stretched for use, which is more convenient and safer during use, and avoids the problem of disconnection of the circuit.
