[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A retractable adapter plug comprises a shell, pins arranged on the lower side of the shell and a power cord arranged on the rear side of the shell, and also comprises a sleeve and a fixing component. The shell is in a rectangular structure, and the sleeve can be respectively sleeved on the upper side or the lower side of the shell, and the sleeve is fixed by the fixing component. When the sleeve is sleeved on the lower side of the shell, a storage space is formed between the sleeve and the shell, and the pins and the power cord can be stored in the storage space.

[0007] In some embodiments, the fixing assembly includes a hook disposed on the opening edge of the shell, surrounding a limiting flange on the outer side of the shell, and a notch is provided on the limiting flange. When the shell is mounted on the shell, the hook can be hooked on the notch.

[0008] In some embodiments, two hooks are disposed on both the left and right sides of the casing, and the two hooks on the same side are symmetrically disposed front to back.

[0009] In some embodiments, an escape opening is provided on the rear side of the casing.

[0010] In some embodiments, anti-slip convex strips are provided on both the left and right side walls of the casing.

[0011] In some embodiments, a guide bevel is provided on the inner side of the opening edge of the casing.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the adapter is not needed, the power cord can be firstly wrapped around the pins on the lower side of the shell, and then the sleeve is set on the lower side of the shell, so that the power cord and the pins are stored and hidden in the storage space formed between the sleeve and the shell, and the pins are further protected. It can effectively prevent the pins from being damaged, and at the same time will not damage the power cord, so that the power cord is fixed more tightly, and the power cord is prevented from bouncing off, which is convenient for users to operate and can extend the service life of the adapter.

[0017] The following specific implementation contents provide a variety of different embodiments or examples for implementing the utility model. Of course, these are only embodiments or examples and are not intended to be limiting. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0018] like Figure 1-Figure 4 A retractable adapter plug is shown, comprising a shell 1, a plug pin 2 arranged on the lower side of the shell 1 and a power cord 3 arranged on the rear side of the shell 1, and also comprising a sleeve 4 and a fixing component. The shell 1 is a rectangular structure, and the sleeve 4 can be respectively sleeved on the upper side or the lower side of the shell 1, and the sleeve 4 is fixed by the fixing component. When the sleeve 4 is sleeved on the lower side of the shell 1, a storage space 5 is formed between the sleeve 4 and the shell 1, and the plug pin 2 and the power cord 3 can be stored in the storage space 5.

[0019] In the utility model, when the adapter is not needed, the power cord 3 can be firstly wound around the pin 2 on the lower side of the shell 1, and then the sleeve 4 can be sleeved on the lower side of the shell 1, so that the power cord 3 and the pin 2 are stored and hidden in the storage space 5 formed between the sleeve 4 and the shell 1, so as to further protect the pin 2 and effectively prevent the pin 2 from being damaged. At the same time, the power cord 3 will not be damaged, so that the power cord 3 is fixed more tightly and the power cord 3 is prevented from bouncing off, which is convenient for the user to operate and can extend the service life of the adapter.

[0020] See also Figure 1-Figure 2 As shown, the fixing assembly includes a hook 21 arranged on the opening edge of the sleeve shell 4, surrounding a limiting flange 22 on the outer side of the shell 1, and a notch 23 is arranged on the limiting flange 22. When the sleeve shell 4 is sleeved on the shell 1, the hook 21 can be hooked on the notch 23.

[0021] No matter the sleeve 4 is sleeved on the shell 1 from top to bottom or from bottom to top, the opening edge of the sleeve 4 can be against the limiting flange 22, and at the same time, the hook 21 can be clamped on the notch 23 to fix the sleeve 4; in addition, since the shell 1 and the hook 21 are made of an integrally molded plastic material, the hook 21 has resilience, so that the sleeve 4 can be disassembled by prying the hook 21 and the notch 23 apart with fingers.

[0022] Furthermore, two hooks 21 are disposed on both the left and right sides of the sleeve shell 4 , and the two hooks 21 on the same side are symmetrically disposed front to back, so that the sleeve shell 4 and the housing 1 can be firmly fixed.

[0023] See also Figure 1-Figure 3 As shown, a clearance opening 41 is provided at the rear side of the housing 4 , and the clearance opening 41 is used to allow the power cord 3 to pass through, so as to facilitate the normal use of the power cord 3 , or to allow the power cord 3 to be stored in the storage space 5 .

[0024] Furthermore, anti-slip convex strips 51 are provided on both the left and right side walls of the casing 4 .

[0025] In order to facilitate the sleeve 4 to be mounted on the housing 1 , a guide bevel 61 is inverted on the inner side of the opening edge of the sleeve 4 .

[0026] Combined with the drawings and the above display and description of the basic principles and main features of the utility model and the advantages of the utility model, the technical personnel in the industry should understand that the utility model is not limited to the above embodiments, and the above embodiments and descriptions are only to illustrate the principles of the utility model.
