[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a pipe-shaped three-prong plug.

[0026] The utility model provides Figure 1-3 The pipe-shaped three-pin plug shown in the figure comprises a plug body 1, a pin 2 and a rubber protective neck 3. The plug body 1 adopts a pipe-shaped structure, the pin 2 is arranged at the end of the plug body 1, and the rubber protective neck 3 is arranged at the tail of the plug body 1; a protective sheet 4 is provided at the end of the plug body 1, and a telescopic cover 5 is fixedly provided between the protective sheet 4 and the plug body 1. The protective sheet 4 and the telescopic cover 5 are both insulating parts to avoid electric shock when the plug body 1 is pulled out. A plug hole 6 is provided on the side of the protective sheet 4 and at a position corresponding to the position of the pin 2; a fixing block 7 is fixedly provided on the top of the protective sheet 4, and a fixing ring 8 is fixedly provided on the top of the plug body 1. A connecting rod 9 is slidably provided inside the fixing ring 8. The connecting rod 9 adopts a square rod, and the fixing ring 8 adopts a square ring. The square structure allows the connecting rod 9 to slide smoothly inside the fixing ring 8 to avoid the connecting rod 9 from rotating. One end of the connecting rod 9 is fixed to the fixing block The top of the fixing ring 8 is provided with a bolt 10 for fixing the connecting rod 9. The rod wall of the connecting rod 9 is provided with a screw hole 13. The end of the bolt 10 is threadedly connected to the screw hole 13. When the pin 2 needs to be protected, the protective sheet 4 is pulled outward so that the telescopic cover 5 is pulled open. At this time, the protective sheet 4 and the telescopic cover 5 can shield and protect the pin 2 to prevent the pin 2 from being exposed and contaminated. When the pin 2 needs to be exposed for use, it is only necessary to push the protective sheet 4 so that the pin 2 passes through the inside of the socket 6. At this time, the telescopic cover 5 is squeezed and contracted to expose the pin 2. The length of the pin 2 here is large enough to ensure that the pin 2 is fully matched with the socket on the socket. During the movement, the protective sheet 4 makes the connecting rod 9 slide inside the fixing ring 8, which can increase the movement stability of the protective sheet 4. Then the position of the connecting rod 9 is fixed by tightening the bolt 10, so that the position of the telescopic cover 5 is fixed.

[0027] In order to enable the protective sheet 4 and the telescopic cover 5 to automatically pop out and protect the pin 2, as shown in FIG. Figure 1As shown, a connecting block 11 is fixedly provided at one end of the connecting rod 9 away from the fixing block 7, a spring 12 is sleeved on the rod wall of the connecting rod 9, and the two ends of the spring 12 are fixedly connected to the connecting block 11 and the fixing ring 8 respectively. After the protective sheet 4 moves in contact with the plug body 1, the telescopic cover 5 is squeezed and contracted. At this time, the connecting block 11 on the connecting rod 9 will stretch the spring 12, so that the spring 12 has an elastic tendency. When the bolt 10 is loosened by hand, the elastic force of the spring 12 makes the protective sheet 4 move automatically and unfold the telescopic cover 5, thereby automatically completing the protection of the pin 2.

[0028] Finally, in order to facilitate the plugging and unplugging of the plug body 1, as shown in FIG. Figure 1 and 4 As shown, pinch blocks 14, buckle blocks 15 and anti-slip grooves 16 are provided on both sides of the plug body 1. The pinch blocks 14 make it easy for human hands to pinch the plug body 1 and complete the plug-in. The buckle blocks 15 make it easy for human hands to pull the plug body 1 outward to separate the plug body 1 from the socket. The anti-slip grooves 16 can increase the friction resistance between the hand and the plug body 1.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
