In the embodiment of the present invention, as shown in fig. 1, the first direction D1 is perpendicular to the top surface of the protection door, and it can be considered that the first direction D1 is along the vertical direction.
The distribution direction D2 of the two first via holes is the same as the distribution direction from the N-pole plug bush to the L-pole plug bush in the socket, where the distribution direction from the N-pole plug bush to the L-pole plug bush refers to the extending direction from the N-pole plug bush to the L-pole plug bush, or the extending direction from the L-pole plug bush to the N-pole plug bush. The embodiment of the utility model provides an in, can be defined as left right direction with the distribution direction D2 of two first via holes, namely, the distribution direction of N utmost point plug bush to L utmost point plug bush is left right direction, for example, N utmost point plug bush is located the left side, and L utmost point plug bush is located the right side, and N utmost point plug bush and L utmost point plug bush here refer to two utmost point plug bushes. Of course, the N-pole and L-pole sockets may also be slaved to the three-pole socket, although in the three-pole socket the N-pole and L-pole sockets are slanted, but one of them is still considered to be on the left and one on the right.
The socket protection door structure is arranged in the socket and is usually positioned between the jack and the plug bush, and is used for preventing an object from being mistakenly inserted into the plug bush through the jack and playing a role in preventing leakage. In the related art, the socket protection door structure includes: the protection door comprises a shell, a protection door positioned in the shell and a torsion spring used for resetting the protection door. However, the current socket protection door mechanism cannot effectively prevent the insertion of the single pole, and there is a risk of electric shock.
The embodiment of the utility model provides a socket shutter structure, as shown in figure 1 and figure 2, this socket shutter structure includes: the device comprises a supporting seat 1, a protective door 2, an elastic reset piece 3, two groups of first stop blocks 12 and two groups of second stop blocks 13; the support seat 1 is provided with two first through holes 11, and the two first through holes 11 correspond to an N-pole plug bush and an L-pole plug bush of the socket respectively; the protection door 2 is movably connected with the support base 1, and the protection door 2 is configured to be capable of moving along a first direction D1 and a second direction D2 in sequence to expose two first vias 11, wherein the first direction D1 is along a direction perpendicular to the top surface of the protection door 2, and the second direction D2 is along a distribution direction of an N-pole insert sleeve and an L-pole insert sleeve of the socket; the elastic reset piece 3 is positioned between the supporting seat and the protective door 2 and is used for resetting the protective door 2.
The protective door 2 is movably connected with the supporting seat 1, so that the protective door 2 can move along the supporting seat 1, and the moving protective door 2 can be switched between an initial state and an avoiding state. When the protective door 2 is in an initial state, the protective door 2 can block two first through holes 11 on the supporting seat 1 so as to protect an N-pole plug bush and an L-pole plug bush in the socket; when the protective door 2 is in the avoiding state, the protective door 2 does not block two first via holes 11 on the supporting seat 1 any more, and the first via holes 11 are exposed, so that the plug is conveniently inserted into the N-pole plug bush and the L-pole plug bush in the socket.

In particular, the seventh and eighth side walls 10311 and 10312 are each disposed obliquely, the distance between the top end of the seventh side wall 10311 and the top end of the eighth side wall 10312 is greater than the distance between the bottom end of the seventh side wall 10311 and the bottom end of the eighth side wall 10312, and the distance between the top end of the seventh side wall 10311 and the top end of the eighth side wall 10312 is also greater than the outer diameter of the outer guide shaft 4, so that the outer guide shaft 4 can easily enter the guide section 1031 for guiding the fitting of the protection door 2 into the support base 1.
In the socket protection door structure provided by the embodiment of the present invention, the seventh side wall 10311, the third side wall 10321, the fifth side wall 10331, and the first side wall 10341 are connected in sequence and are integrally formed; the eighth side wall 10312, the fourth side wall 10322, the sixth side wall 10332, and the second side wall 10342 are connected in sequence and are integrally formed.

Wherein the movement of the protective door 2 described herein comprises: the movement of the protective door 2 in the second direction D2 under the double latch actuation and the tilting movement of the protective door 2 under the single latch actuation.
The inner guide shaft 9 may be arc-shaped cylindrical or cylindrical, the longitudinal direction of the inner guide shaft 9 is the same as the longitudinal direction of the outer guide shaft 4, and the circumferential direction of the inner guide shaft 9 is also the same as the circumferential direction of the outer guide shaft 4. In this way, the movement of the inner guide shaft 9 on the guide surface 51 of the guide block 5 is smoother.
Illustratively, as shown in fig. 3, the protective door 2 includes: the door panel 201 and the frame 202 are protected, the frame 202 is movably connected to the support base 1, and the inner guide shafts 9 are located inside two side walls of the frame 202 extending in the second direction D2. The outer guide shafts 4 and the inner guide shafts 9 are respectively located outside and inside the side wall of the frame body 202, and the outer guide shafts 4 and the inner guide shafts 9 located on the same side can be opposite to each other one by one, so that the structure is favorable for preparation and improvement of the strength of the protective door 2.
Illustratively, when the protective door 2 moves along the second direction D2 under the driving of the double-bolt, the inner guide shaft 9 is contacted with the guide surface 51, so that the guide surface 51 is used to guide the movement of the protective door 2 in the second direction D2, and the movement smoothness of the protective door 2 can be further improved in cooperation with the movement of the outer guide shaft 4 in the guide groove 103, so that the protective door 2 can be more easily moved to the avoiding state.
Further, the inner guide shaft 9 is brought into contact with the guide surface 51 of the guide block 5 in advance before the outer guide shaft 4 enters the second guide section 1034 from the first guide section 1033, which is advantageous in improving the service life of the protective door 2. In this case, the inclination angle of the second side wall 10342 of the second guide section 1034 is made larger than or equal to the inclination angle of the guide surface 51, so that the inner guide shaft 9 comes into contact with the inner guide shaft 9 in advance, ensuring smooth opening of the protective door 2.
When the protective door 2 is reset, the outer guide shaft 4 is brought into contact with the second side wall 10342 of the second guide section 1034 to guide the reset movement of the outer guide shaft 4 in the second direction D2, and the guide surface 51 of the guide block 5 is no longer in contact with the inner guide shaft 9.
Illustratively, as shown in fig. 2, when the protection door 2 is tilted under the driving of a single pin, that is, when the side of the protection door 2 to be driven is tilted downward, the inner guide shaft 9 is brought into contact with the guide surface 51, and the tilt motion of the protection door 2 is guided by the guide surface 51, specifically, the guide surface 51 is used as a stress point to perform a seesaw motion, so that the motion of the protection door 2 is smoother.

In particular, the dislocation arrangement of the guide groove 103 and the bottom supporting part 101 is combined, so that the stress point of the protective door 2 moving to the avoiding state is more inclined to the bottom supporting part 101 of the supporting seat 1, the stress of the outer guide shaft 4 is dispersed, the requirement on the structural rigidity of the protective door 2 is reduced, the matching of the outer guide shaft 4 and the guide groove 103 is easier, the deformation is not easy to occur, and the service life of the protective door structure of the socket is prolonged.
In addition, the mode of transferring the stress point to the bottom supporting part 101 of the supporting seat 1 is also beneficial to reducing the thickness of the protective door 2, so that the maximum thickness of the decorative panel of the socket can be less than or equal to 4mm when the space with the reduced thickness of the protective door 2 is correspondingly transferred to the socket on the premise that the plug contact plug bush meets the national standard of H1.
In some possible implementations, as shown in fig. 3, the frame 202 of the protection door 2 comprises: the side frame 2021 and the panel frame 2022, the panel frame 2022 is located inside the side frame 2021, two avoiding grooves 2023 are arranged on the bottom wall of the panel frame 2022, and the two avoiding grooves 2023 correspond to the two guide blocks 5 one by one; the escape groove 2023 receives at least the top of the guide block 5 when the protective door 2 moves in the second direction D2.
The avoiding groove 2023 is located on the surface of the panel frame 2022 facing the guide block 5, and the design of the avoiding groove 2023 is favorable for reducing the thickness of the protective door 2 and further the thickness of the socket, for example, the thickness of the external protective door panel 201 of the socket is less than or equal to 4mm, which also reduces the manufacturing cost of the socket.
In some examples, the escape groove 2023 can receive not only the top of the guide block 5 (because the top of the guide block 5 corresponds to the maximum height of the guide block 5) when the protective door 2 moves in the second direction D2, but further, the escape groove 2023 can receive the entire guide block 5. In this way, the structure of the escape groove 2023 can be made the same as that of the guide block 5, so that the guide block 5 can be fitted snugly into the escape groove 2023.
In some examples, before the outer guide shaft 4 of the protective door 2 enters the second guide section 1034, the inner guide shaft 9 is first brought into contact with the guide surface 51 of the guide block 5, so that the inner guide shaft 9 performs a movement of the second direction D2 along the guide surface 51 to facilitate the movement of the protective door 2. Further, in this process, at least the top portion of the guide block 5 is caused to enter the escape groove 2023.
