Description

Technical Field

[0001] This utility model relates to the field of plugs, and in particular to an adjustable plug. Background Technology

[0002] A plug is an interface device used to connect electrical equipment to a power circuit. It is widely used in homes, offices, and industrial equipment. A plug usually consists of two parts: the plug body and the prongs.

[0003] With the development of globalization, the cross-border use of electronic devices has become more and more common. Different countries and regions have different electrical standards, and the shape, size and other parameters of plugs and sockets often differ. Traditional plugs can usually only be compatible with the standards of specific countries or regions, which means that users need to carry multiple adapters when traveling internationally or using electrical equipment across borders. This makes traditional plugs less applicable and inconvenient to use and carry. Utility Model Content

The support device 3 can support the connection between the wire 4 and the plug body 1.

[0031] Figure 2 and Figure 3One end of the first pin 21 is connected to one side of the plug body 1. A first spring 22 is symmetrically fixedly connected to one side of the plug body 1. One end of the first spring 22 is fixedly connected to one side of the second pin 23. A slot 24 is symmetrically opened on one side of the second pin 23. A protective cover 25 is fixedly connected to one side of the plug body 1. A sliding hole 26 is symmetrically opened on one side of the protective cover 25. The first pin 21, the first spring 22, and the second pin 23 are all set in the inner wall of the sliding hole 26. The outer surface of the first pin 21 is slidably connected to one side of the second pin 23. A locking hole 27 is symmetrically opened on one side of the inner wall of the sliding hole 26. The two ends of the locking rod 28 are respectively inserted into the inner walls of the locking hole 27 and the slot 24. A second spring 29 is sleeved and connected to the outer surface of both ends of the locking rod 28. The two ends of the second spring 29 are fixedly connected to one side of the protective cover 25 and the locking rod 28, respectively. Depending on daily usage needs, when using a socket with a round hole, first pull the lever 28 to one end to a certain distance, causing the second spring 29 to stretch and pull one end out of one of the slots 24. Then, press the second pin 23 inward in the inner wall of the sliding hole 26 to a certain position, causing the first spring 22 to retract and exposing the first pin 21 wrapped inside. Release the lever 28, and under the reset action of the second spring 29, both ends of the lever 28 are inserted into the slots 24 on the two second pins 23 respectively, limiting and fixing them. This makes it convenient for the first pin 21 to be used with sockets with round holes. Conversely, the second pin 23 can slide out under the reset action of the first spring 22, wrapping the first pin 21 to form a rectangular pin, and then be fixed by the lever 28. This allows it to be used with sockets with rectangular holes, making it easy to adapt to socket standards of different countries, improving the compatibility of the plug body 1, and making it convenient to use and carry. It should be noted that, in order not to affect the use of the plug body 1, the first pin 21, and the second pin 23, the protective cover 25, the locking lever 28, the first spring 22, and the second spring 29 are all made of insulating material.

[0032] Figure 2 and Figure 3 The cross-section of the lever 28 shown is U-shaped, and a groove 210 is provided on one side of the lever 28. By setting the lever 28 in a U-shape and providing a groove 210 on one side, it can be easily pulled manually. Several telescopic rods 211 are symmetrically fixedly connected to one side of the plug body 1. One end of the telescopic rod 211 is fixedly connected to one side of the second pin 23, and the telescopic rod 211 is sleeved and connected to the first spring 22. By setting the telescopic rod 211, the inner wall of the first spring 22 can be supported and reinforced, making it less prone to damage during use and improving its service life.

[0033] Figure 4The support device 3 shown includes a support rod 31, one side of which is fixedly connected to one side of the plug body 1. An elastic arc block 32 is fixedly connected to one side of the support rod 31, and the wire 4 is inserted into the inner wall of the elastic arc block 32. When using the plug body 1, the wire 4 can be inserted into the inner wall of the elastic arc block 32 for restraint. In this way, the support rod 31 can support the connection between the wire 4 and the plug body 1, preventing damage and breakage due to prolonged bending during use, thus improving the service life of both the plug body 1 and the wire 4.

[0034] Figure 4 The inner wall of the elastic arc block 32 shown is fixedly connected with an anti-slip block 33, which is made of rubber. By setting the anti-slip block 33, the contact friction of the inner wall of the elastic arc block 32 is increased, making it easier for the wire 4 to be inserted into the inner wall of the elastic arc block 32 without wobbling, resulting in a more secure and stable position. Limiting blocks 34 are fixedly connected to both ends of the elastic arc block 32, and the two limiting blocks 34 are fixedly at an angle on both sides of the opening of the elastic arc block 32. By setting the limiting blocks 34, the area at the entrance of the elastic arc block 32 is increased, making it easier for the wire 4 to be quickly aligned and inserted. Reinforcing rods 35 are fixedly connected to both sides of the support rod 31, with one side of the reinforcing rod 35 fixedly connected to one side of the elastic arc block 32. By setting the reinforcing rods 35, the connection area between the elastic arc block 32 and the support rod 31 is increased, making the connection more secure and stable, and less prone to breakage or damage.

[0035] Working principle: Depending on daily usage needs, when the socket hole is round, first pull the lever 28 to one end to a certain distance, causing the second spring 29 to stretch, so that one end of it is pulled out from one of the slots 24. Then, press the second pin 23 inward in the inner wall of the sliding hole 26 to a certain position, causing the first spring 22 to retract, exposing the first pin 21 wrapped inside. Release the lever 28, so that under the reset action of the second spring 29, both ends of the lever 28 are inserted into the slots 24 on the two second pins 23 respectively, limiting and fixing them. In this way, the first pin 21 can be used with sockets with round holes. Conversely, the second pin 23 can slide out under the reset action of the first spring 22, wrapping the first pin 21 to form a rectangular pin, and then be fixed by the lever 28. In this way, it can be used with sockets with rectangular holes, making it easy to adapt to socket standards of different countries, improving the usability of the plug body 1, and making it easy to use and carry. It should be noted that, in order not to affect the use of the plug body 1, the first pin 21, and the second pin 23, the protective cover 25, the locking lever 28, the first spring 22, and the second spring 29 are all made of insulating material.

[0036] When using the plug body 1, the wire 4 can be inserted into the inner wall of the elastic arc block 32 to limit its movement. In this way, the support rod 31 can support the connection between the wire 4 and the plug body 1, making it less prone to damage and breakage due to prolonged bending during use, thereby improving the service life of the plug body 1 and the wire 4.
