Description

Technical Field

[0001] The utility model relates to the technical field of power plugs, in particular to a rotatable power plug. Background Art

[0002] The power plug is a device that connects electrical appliances and other devices to the power supply. Power sockets and plugs vary in appearance, grade, size and type depending on the country and region.

[0003] For existing power plugs, see Figure 1 In order to facilitate the adjustment of the angle of the power plug connection line, it generally includes a plug and a fixed shell rotatably connected to the plug, wherein the connection line is connected to the fixed shell, and the plug is arranged at the lower end of the plug. When in use, the fixed shell can rotate around the bottom shell to achieve multi-angle adjustment. In order to limit the rotation angle of the bottom shell, the existing rotatable power plug is provided with a plurality of snap-in protrusions on the upper edge of the bottom shell, and a snap-in groove is provided at the corresponding position of the fixed shell, so that after the bottom shell is rotated to a certain angle, the snap-in protrusion is snapped into the snap-in groove, which is convenient for users to control the rotation angle.

[0004] The above-mentioned rotatable power plug has multiple snap-in protrusions arranged on the edge of the upper end of the bottom shell. The snap-in protrusions extend 0.2mm beyond the snap-in grooves. After the snap-in protrusions are snapped into the snap-in grooves, the force direction is different from the rotation direction, so that there is hard friction between the bottom shell and the fixed shell, and the wear of both is large, resulting in a short life. At the same time, the rotation requires a large external force and the operation feel is poor. Utility Model Content

[0005] The utility model aims to provide a rotatable power plug to solve the problem that the existing rotatable power plug has a poor rotation operation feel.

[0006] The utility model provides a rotatable power plug, comprising a plug, a fixed shell rotatably connected to the plug, and a plug connected to the plug, wherein a guide block is provided in the middle of the plug, a clamping protrusion is provided in the middle of the guide block, a clamping groove is provided at a position of the fixed shell corresponding to the clamping protrusion, and the clamping protrusion is longitudinally arranged in the middle of the guide block on the plug.

[0007] The above-mentioned rotatable power plug is configured such that the snap-in protrusion is longitudinally arranged in the middle of the guide block on the plug, and a snap-in groove is correspondingly arranged on the fixed shell. When the user needs to rotate the plug, the user's force is opposite to the direction of the friction force of the elastic snap-in plate on the snap-in protrusion. Because the elastic snap-in plate has a certain elastic deformation ability, the snap-in protrusion is easier to be inserted into or removed from the snap-in groove. The user can rotate the plug with less force, the operation feels good, and the snap-in protrusion is not easy to wear and has a long service life.

[0008] Furthermore, guide blocks are provided in the middle and on both sides of the plug.

[0009] Furthermore, the width of the clamping protrusion is smaller than the width of the clamping groove of the fixing shell.

[0010] Furthermore, a clamping groove is provided at a position of the fixing shell corresponding to the clamping protrusion, and the clamping groove is provided in the middle of the clamping plate.

[0011] Furthermore, a plurality of reinforcing blocks are provided at the connection between the clamping plate and the fixing shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings. Several embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 2 and Figure 3 The utility model provides a rotatable power plug, including a bottom shell 10, a fixed shell 20 rotatably connected to the plug 10, and a plug 30 connected to the plug 10, a guide block 60 is provided in the middle of the plug 10, a snap-on protrusion 42 is provided in the middle of the guide block 60, a snap-on groove 50 is provided at a position corresponding to the snap-on protrusion 42 of the fixed shell 20, and the snap-on protrusion 42 is longitudinally arranged in the middle of the guide block 60 in the middle of the plug 10.

[0022] The above-mentioned rotatable power plug is configured such that the snap-in protrusion 42 is longitudinally arranged in the middle of the guide block 60 on the plug 10, and a snap-in groove 50 is correspondingly arranged. When the user needs to rotate the plug 10, the user's force and the friction force of the flexible snap-in plate 70 on the snap-in protrusion 42 are in opposite directions. Moreover, because the flexible snap-in plate 70 has a certain deformation ability, the snap-in protrusion 42 is easier to be inserted into or removed from the snap-in groove 50.
