DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-7 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] As shown in the figure, a European socket includes a panel 1, a panel frame 2, a fixing frame 3, a safety door 4, a reset spring 5, a grounding spring 6, a phase line socket 7, a base 8, a limiting frame 9 and a connecting frame 10, wherein the phase line socket 7 is fixedly arranged in the base 8, the grounding spring 6 is arranged in a cavity provided on the base 8, the connecting frame 10 is covered on the base 8 to cover the horizontal flat portion of the phase line socket 7 and the grounding spring 6, and the connecting frame 10 is provided with a first socket 101 aligned with the phase line socket 7, the limiting frame 9 is arranged on the connecting frame 10, and the limiting frame 9 is provided with a second socket 91 aligned with the first socket 101, the fixing frame 3 is arranged on the limiting frame 9, and the fixing frame 3 is formed with a rotating shaft portion 31 extending into the limiting frame 9, and the fixing frame 3 is provided with a rotating shaft portion 31 extending into the limiting frame 9. A third insertion hole 32 aligned with the second insertion hole 91 is provided, the safety door 4 is sleeved on the rotating shaft portion 31 and located in the limiting frame 9, a limiting portion 93 for limiting excessive rotation of the safety door 4 is formed in the limiting frame 9, the reset spring 5 is arranged in the limiting frame 9 and abuts against the safety door 4, a mounting bolt 11 passes through the rotating shaft portion 31, the connecting frame 10, the grounding spring 6 and the base 8 in sequence and is screwed with a locking piece 12, the mounting bolt 11 cooperates with the locking piece 12 to pull the fixing frame 3, the limiting frame 9, the connecting frame 10 and the base 8 together so that the rotating shaft portion 31 abuts against the inner wall of the limiting frame 9, thereby fixing the fixing frame 3, the limiting frame 9, the connecting frame 10 and the base 8, the panel frame 2 is fixedly connected to the base 8, and the panel 1 is fixedly connected to the panel frame 2.

[0026] Specifically, a positioning pin 33 is formed on the fixing frame 3, and a positioning pin hole 92 matching the positioning pin 33 is formed on the limiting frame 9. The positioning pin 33 is inserted into the positioning pin hole 92. The positioning pin 33 cooperates with the positioning pin hole 92 to limit the connection between the fixing frame 3 and the limiting frame 9, so that the fixing frame 3 and the limiting frame 9 bracket will not produce relative rotation, thereby ensuring the stability of the connection between the two.

[0027] Specifically, a positioning block 93 is formed on the limit frame 9, and a positioning hole 102 matching the positioning block 93 is formed on the connecting frame 10. The positioning block 93 passes through the positioning hole 102 and abuts against the horizontal portion of the grounding spring 6. The positioning block 93 and the positioning hole 102 cooperate to limit the connection between the limit frame 9 and the connecting frame 10, so that there will be no relative rotation between the limit frame 9 and the connecting frame 10, thereby ensuring the stability of the connection between the two.

[0028] Specifically, a guide slope 41 located below the third insertion hole 32 is formed on the upper surface of the safety door 4 , and the guide slope 41 extends along an arc cocentric with the rotating shaft portion 31 , and the higher end of the guide slope 41 is inserted into the third insertion hole 32 .

[0029] In the above embodiment, when the plug is not inserted, the safety door 4 rotates along the rotating shaft portion 31 in the limiting frame 9 under the action of the return spring 5, and is acted upon by the limiting portion 93 so that the higher end of the guiding inclined surface 41 is inserted into the third insertion hole 32, so that the third insertion hole 32 is shielded by the safety door 4. At this time, when an object is inserted into any of the third insertion holes 32 and contacts the guiding inclined surface 41 on one end of the safety door 4, the safety door 4 is forced to swing so that the higher end of the guiding inclined surface 41 at the other end is further inserted into the third insertion hole 32 to limit the rotation of the safety door 4. At this time, the safety door 4 cannot be opened by rotating. The third jack 32 achieves the purpose of safety protection. When the plug is inserted, the two pins of the plug simultaneously extend into the two third jacks 32 and contact the two guide slopes 41 on both ends of the safety door 4, and simultaneously push the higher ends of the two guide slopes 41 away from the third jack 32. Then, as the plug continues to be inserted, the pins of the plug push the safety door 4 to rotate and fully open under the action of the guide slopes 41, so that the pins of the plug can continue to be inserted downward, and after passing through the second jack 91 and the first jack 101, they are inserted into the phase line socket 7, and at the same time, the vertical part of the grounding spring 6 abuts against the grounding contact of the plug. During use of the above-mentioned socket, the safety door 4 remains in rotation within the limit frame 9, and the limit frame 9 provides support for the safety door 4 when it rotates, thereby ensuring the stability of the safety door 4 during rotation and preventing it from getting stuck, thereby ensuring the normal use of the socket. In addition, since the guide bevel 41 extends along an arc that is cocentric with the rotating shaft portion 31, the plug pins of the plug always keep in contact with the guide bevel 41 during the process of the plug pins pushing the safety door 4 to rotate, making it easier for the plug pins to push the safety door 4 to rotate, thereby making the process of inserting the plug smoother.

[0030] Preferably, the guide bevel 41 is in a concave arc shape and matches the end of the plug pin. When the plug pin contacts the guide bevel 41 and pushes the safety door 4, the plug pin is better maintained on the guide bevel 41 and in contact with the guide bevel 41, thereby making the process of inserting the plug smoother.

[0031] Preferably, an arc-shaped spring pile 42 is formed on the safety door 4, the reset spring 5 is sleeved on the spring pile 42 and the other end is against the inner wall of the limit frame 9, and the reset spring 5 is also bent into an arc shape after being sleeved on the arc-shaped spring pile 42. When the plug is unplugged, the force of the reset spring 5 to push the safety door 4 is in the opposite direction of the rotation of the safety door 4, so that the safety door 4 is reset more smoothly under the action of the reset spring 5, ensuring that the safety door 4 can cover the third jack 32 to play a role in safety protection.

[0032] Preferably, a swing protrusion 43 with an arc-shaped lower end is formed on the lower surface of the safety door 4, and the lower end of the swing protrusion 43 abuts against the inner wall of the limit frame 9 to provide support for the safety door 4, and provides a swing fulcrum for the safety door 4 when the safety door 4 swings to play a safety protection role, so that the safety door 4 swings faster and smoother, thereby ensuring that the safety door 4 can play a safety protection role.

[0033] Preferably, a positioning protrusion 61 is formed on each side end of the horizontal flat portion of the grounding spring 6, and two positioning grooves 81 are formed in the base 8, which penetrate the base 8 upward and match the positioning protrusion 61. The positioning protrusion 61 is inserted into the positioning groove 81, and the positioning protrusion 61 cooperates with the positioning groove 81 to limit the grounding spring 6, so that the grounding spring 6 will not deflect when it contacts the grounding contact of the plug, thereby ensuring the stability of the contact between the grounding spring 6 and the grounding contact of the plug.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
