DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] like Figure 1 As shown, a rotatable three-hole socket comprises an upper shell 1, a lower shell 2 and a rotating disk 3. The lower shell 2 is used to be fixed on the wall, the upper shell 1 is buckled on the lower shell 2, the rotating disk 3 is rotatably connected to the upper shell 1, and a triangular socket 4 is arranged on the rotating disk 3.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, a clip 5 is provided in each socket corresponding to the triangular socket 4, and the three clips 5 are all located inside the rotating disk 3, and a conductive column 6 is provided at the lower end of the three clips 5. An insulating sleeve 7 is provided outside the upper half of each conductive column 6 to prevent mutual interference between the three conductive columns 6, making electricity use safer.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, an annular ground wire groove 12, neutral wire groove 13 and live wire groove 14 are respectively opened inside the lower shell 2. The ground wire groove 12, neutral wire groove 13 and live wire groove 14 are concentrically arranged and three conductive columns 6 are separately embedded therein. Conductive metal grooves 15 are provided at the bottom of the ground wire groove 12, neutral wire groove 13 and live wire groove 14.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, each conductive metal slot 15 is provided with a terminal 16 at the lower end, and the terminal 16 is connected to the corresponding ground wire, neutral wire and live wire in the outside world through screws 17, so as to realize the quick wiring of the entire three-hole socket, which is convenient for the installation and use of the three-hole socket.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, a mounting spring 8 is provided at the lower end of the conductive column 6, and a conductive sheet 9 is provided at the lower end of the mounting spring 8. The conductive sheet 9 is used to contact the conductive metal groove 15. Therefore, after the upper shell 1 and the lower shell 2 are buckled together, under the action of the mounting spring 8, the conductive column 6 is always in a connected state to prevent power failure, thereby ensuring the stability of the three-hole socket when in use.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the rotating disk 3 is vertically slidably connected to the upper shell 1, and a push-type self-locking buckle 10 is provided between the middle position of the upper end of the lower shell 2 and the middle position of the lower end of the rotating disk 3. Therefore, the rotating disk 3 can be fixed or unlocked by pressing, and the rotating disk 3 can be fixed after rotation to prevent rotation during operation.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, compression springs 18 are provided between the lower shell 2 and both sides of the rotating disk 3, and the upper end of the compression spring 18 is rotatably connected to the rotating disk 3. Therefore, when the rotating disk 3 is pressed, the rotating disk 3 can be automatically popped out, which facilitates the control of the rotation of the rotating disk 3.

[0034] When in use, the plug of the electrical equipment will be inserted into the triangular socket 4, and the three clips 5 will respectively lock the plug. Since the three wire posts are in contact with the three conductive metal slots 15 through the springs and the conductive sheets 9 respectively, the conductive metal slots 15 are connected to the corresponding ground wire, neutral wire and live wire through the terminal 16 and the screw 17, so that the electrical equipment will receive power from the external power supply.

[0035] When the triangular socket 4 needs to be rotated, the rotating disk 3 is pressed to make the push-type self-locking buckle 10 pop open. Due to the elastic force of the compression spring 18, the rotating disk 3 pops outward and is in a rotatable state. At this time, the rotating disk 3 can be rotated 360°. When the rotating disk 3 is rotated to the required angle, the rotating disk 3 is pressed. At this time, the push-type self-locking buckle 10 is locked, thereby fixing the rotating disk 3.

[0036] Therefore, a rotatable rotating disk 3 is provided to adjust the orientation of the triangular socket 4 on the rotating disk 3. No matter which orientation the plug of the electrical device is, the rotating disk 3 can be adjusted to adapt to the plug of the electrical device. The plug of the electrical device will not be bent, thereby effectively protecting the plug of the electrical device.

[0037] Embodiment 2:

[0038] like Figure 4As shown, a rotatable three-hole socket is different from Example 1 in that: plug rods 19 are provided on both sides of the upper shell 1, through holes 20 for the plug rods 19 to pass through are penetrated on both sides of the lower shell 2, and a locking ring 21 is provided on the plug rod 19 to press the outer wall of the lower shell 2 to achieve the clamping fixation of the plug rod 19, thereby achieving the clamping fixation between the upper shell 1 and the lower shell 2.

[0039] like Figure 4 As shown, the tail end of the plug rod 19 is sleeved with a plug tube 22, which is used to be embedded in the mounting column on the wire box. The outer wall of the plug tube 22 is provided with multiple circles of clamping rings 23, the end of the plug rod 19 is provided with a pair of elastic hooks 24, and the inner wall of the plug tube 22 is provided with a clamping ring 25 for the hook 24 to hook.

[0040] When the three-hole socket needs to be installed, the insert tube 22 is first inserted into the installation column on the wire box, and the insert tube 22 is fixed under the action of the clamping ring 23. Then the upper shell 1 and the lower shell 2 are buckled together, and the insertion rod 19 passes through the through hole 20, and the locking ring 21 is pressed against the outer wall of the lower shell 2, so that the upper shell 1 and the lower shell 2 are clamped and fixed.

[0041] Then, the insertion rod 19 is inserted into the insertion tube 22. At this time, the clamping ring 25 first presses the clamping hook 24 to deform and move closer to each other, until the lower shell 2 is installed, the clamping hook 24 is separated from the clamping ring 25 and hooked to the inner wall of the clamping ring 25, thereby fixing the clamping hook 24 and further realizing the rapid installation and fixation of the entire three-hole socket.

[0042] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
