[0039] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0040] The socket includes a socket body and a protective door structure. The socket body includes multiple clamping sleeves. One end of each sleeve is connected to the power supply of the line, and the other end is used to connect the plug. The sleeve has a clamping effect and can cooperate with the pin 5 of the plug to achieve a clamping connection. It can fix and limit the plug. The protective door structure is set in the socket body and is isolated between the socket hole and the sleeve.

[0041] The protective door structure in this embodiment is a waterproof socket protective door structure 10, such as... Figures 1-3 As shown, the waterproof socket protection door structure of this embodiment includes a housing 1, an elastic sealing member 2, a protection door 3, and an elastic component 4. The housing 1 is provided with a first through hole 11 for the pin 5 to pass through. The sealing member 2 is correspondingly provided with the first through hole 11 and connected to the inner side of the housing 1 near the protection door 3, and is located between the first through hole 11 and the protection door 3. The sealing member 2 is provided with a through hole 22 corresponding to the first through hole 11 for the pin 5 to pass through.

[0042] The protective door 3 can move between a first position and a second position. The elastic component 4 is connected to the protective door 3 and drives the protective door 3 to move from the second position to the first position. The protective door 3 can move from the second position to the first position when subjected to force.

[0043] When the protective door 3 is in the first position, the elastic component 4 drives the protective door 3 to fit tightly against the sealing component 2 and blocks the through hole 22. The force applied by the elastic component 4 to the protective door 3 has a component force opposite to the direction of the insertion of the pin 5 into the first through hole 11.

[0044] When the protective door 3 is in the second position, the protective door 3 is offset from the through hole 22, and the protective door 3 releases its obstruction of the through hole 22.

[0045] In this embodiment, the waterproof socket protective door structure 10 provides an elastic sealing element 2 between the first through hole 11 and the protective door 3. When the protective door 3 is in the first position, the force applied to the protective door 3 by the elastic element 4 has a component force opposite to the direction of the insertion of the pin 5 into the first through hole 11, causing the protective door 3 to fit tightly with the sealing element 2, sealing the first through hole 11 and preventing water from entering the socket. Thus, the waterproof socket of this embodiment can be used in outdoor or indoor bathroom areas, eliminating the need for a protective cover to prevent water or other water from entering the socket. Of course, a protective cover can also be installed.

[0046] like Figures 1-3 As shown in the figure, a preferred embodiment of the waterproof socket protection door structure 10 includes a housing 1, a sealing member 2 disposed on the inner side of the top wall of the housing 1, an elastic member 4 connected to the housing 1, and a protection door 3 connected to the elastic member 4. The housing 1 is used to protect the components inside the housing 1 and block water. Only a portion of the structure of the housing 1 is schematically shown in the figure. A first through hole 11 is provided on the top wall of the housing 1. The sealing member 2 is fixedly installed on the inner side of the top wall of the housing 1 and fits tightly against the housing 1. The through hole 22 of the sealing member 2 is correspondingly provided with the first through hole 11. The pin 5 can pass through the first through hole 11 and the through hole 22.

[0047] An elastic component 4 is provided between the housing 1 and the protective door 3. The elastic component 4 drives the protective door 3 to move to a first position that blocks the through hole 22. When the protective door 3 is in the first position, the elastic component 4 applies a force to the protective door 3. The force applied by the elastic component 4 to the protective door 3 has a component force opposite to the direction of the insertion of the pin 5 into the first through hole 11, so that the protective door 3 fits tightly with the sealing member 2 and blocks the through hole 22, preventing water from entering. When the pin 5 is inserted into the through hole 22, it applies a force to the protective door 3. The elastic component 4 is compressed, and the protective door 3 moves away from the first through hole 11, that is, moves to a second position. The pin 5 passes through the first through hole 11 and the through hole and is inserted into the socket sleeve. When the pin 5 is pulled out of the first through hole 11 and the through hole 22, the elastic component 4 drives the protective door to move towards the first through hole 11, that is, moves to the first position. After the protective door 3 returns to the first position, it fits tightly with the sealing member 2 to prevent water from entering the socket.

[0048] like Figures 2-4As shown, in a preferred embodiment of the sealing element 2, the sealing element 2 is elastic, flat, and made of silicone, rubber, etc. The size of the sealing element 2 is larger than the size of the first through hole 11, so that the protective door 3 can compress the sealing element 2 under the drive of the elastic component 4, ensuring airtightness. In this embodiment, the size of the through hole 22 of the sealing element 2 is the same as the size of the first through hole 11. Alternatively, the size of the through hole 22 of the sealing element 2 can also be smaller than the size of the first through hole 11, or smaller than the size of the pin 5, so that when the pin 5 passes through the first through hole 11 and is inserted into the through hole 22, it can compress the through hole 22 to deform and pass through it. For example, when the pin 5 is not inserted, the through hole 22 has a gap. When the pin 5 is inserted into the first through hole 11, it compresses the sealing element 2 to open the through hole 22, and the sealing element 2 and the peripheral wall of the pin 5 fit tightly together, preventing water from flowing into the socket from the peripheral wall of the pin 5. For example, in another embodiment, the through hole 22 is closed when the pin 5 is not inserted. The through hole 22 of the sealing member 2 has a raised sealing flap to close the through hole 22. When the pin 5 is inserted into the first through hole 11, it pushes open the sealing flap and compresses the sealing member 2 to open the through hole 22. The sealing member 2 and the peripheral wall of the pin 5 fit tightly together to prevent water from flowing into the socket from the peripheral wall of the pin 5. After the pin 5 is pulled out, the sealing flap automatically and elastically resets. The sealing flap can be set on one side wall of the through hole 22, or on two opposite side walls, and one or more sets of sealing flaps can be provided. Preferably, a chamfer can be provided at the entrance of the through hole 22 to facilitate the insertion of the pin 5.

[0049] like Figure 3 In the illustrated embodiment, the protective door 3 slides along the first slide rail 13 between a first position and a second position. The first slide rail 13 is inclined relative to the direction in which the pin 5 is inserted into the first through hole 11, so that when the protective door 3 is in the first position, the elastic component 4 drives the protective door 3 to fit tightly against the sealing member 2. That is, the sliding direction of the protective door 3 is not the traditional horizontal setting, nor is it perpendicular to the direction in which the pin 5 is inserted into the first through hole 11. Thus, the force exerted by the elastic component 4 on the protective door 3, guided by the first slide rail 13, has a component force opposite to the direction in which the pin 5 is inserted into the first through hole 11, ensuring that the protective door 3 fits tightly against the sealing member 2.

[0050] Preferably, the sealing element 2 is bonded and sealed to the inner side of the top wall of the housing 1 using a water-proof grease adhesive. Of course, in other embodiments, the sealing element 2 can also be fixedly connected to the housing 1 using other structures. For example, in a less desirable embodiment, the sealing element 2 is provided with a fixing bracket around its peripheral wall; the fixing bracket is made of a rigid material and is used to fix the sealing element 2; the fixing bracket is fixedly installed on the inner side of the top wall of the housing 1.

[0051] The cross section of the sealing member 2 in this embodiment is rectangular. Of course, the cross section of the sealing member 2 can also be circular or other polygonal shapes. In addition, the sealing member 2 can also be provided with other mounting structures or protrusions or grooves or other structures as needed.

[0052] As shown in Figure 1 and 7 , one preferred embodiment of the first slide 13, two first slides 13 are oppositely arranged on the two side walls of the shell 1, the first slide 13 is inclined downward away from the direction of the first through hole 11, the sliding part of the protective door 3 is inserted into the first slide 13, and the sliding part of the protective door 3 slides in the first slide 13, so that the protective door 3 can exert an upward force on the sealing member 2. When the protective door 3 slides from the second position to the first position, the protective door 3 slides back to the first position and tightly fits with the sealing member 2. This embodiment adopts an inclined structure of the first slide 13, and cooperates with the sliding of the protective door 3, so that when the protective door 3 is in the first position, the protective door 3 exerts a force on the sealing member 2, and the sealing is better; when the protective door 3 can move from the second position to the first position, the protective door 3 slides more smoothly to the sealing member.

[0053] Preferably, the first slide 13 is an inclined downward long hole and penetrates the side wall of the shell 1, and the sliding part slides in the first slide 13. That is, as shown in the direction of Figure 7 , the first slide 13 extends in the horizontal direction and the vertical direction away from the direction of the first through hole 11. Preferably, the first slide 13 is an inclined downward long groove, and the sliding part slides in the first slide 13. That is, as shown in the direction of Figure 7 , the first slide 13 extends in the horizontal direction and the vertical direction away from the direction of the first through hole 11. The long groove can be a groove formed on the side wall of the shell 1, or a long groove formed between the sliding protrusions arranged in parallel on the shell 1.

[0054] As other embodiments, the first slide 13 can also be an inclined long sliding protrusion, and the protective door 3 is provided with a sliding groove which is sleeved on the long sliding protrusion and cooperates with the sliding.

[0055] Of course, the housing 1 may also omit the first slide rail 13, and the protective door 3 may be rotatably configured, rotating between a first position and a second position. The rotation axis of the protective door 3 is perpendicular to the direction in which the pin 5 is inserted into the first through hole 11, so that when the protective door 3 is in the first position, the elastic component 4 drives the protective door 3 to fit tightly against the sealing element 2. That is, the plane in which the protective door 3 rotates is not parallel to the plane where the first through hole 11 is located, but perpendicular to the plane where the first through hole 11 is located.

[0056] Specifically, the protective door 3 is rotatably installed inside the housing 1. The elastic component 4 is provided between the protective door 3 and the housing 1. The elastic component 4 drives the protective door 3 to rotate to the first position. The elastic component 4 applies a rotational force to the protective door 3, so that the protective door 3 and the sealing member 2 are tightly engaged, thereby blocking the through hole 22. The pin 5 passes through the through hole 22 and applies force to the protective door 3, causing the protective door 3 to rotate and release the blocking of the through hole 22, that is, the protective door 3 is in the second position. When the pin 5 is pulled out of the through hole 22, the elastic component 4 applies a rotational force to the protective door 3, causing the protective door 3 to return from the second position to the first position, thereby blocking the sealing member 2.

[0057] The housing 1 in this embodiment includes a top cover 14, and the first slide rail 13 is disposed on the top cover 14. It should be noted that the first slide rail 13 may not be disposed on the top cover 14. Figure 7 It can be placed on the upper cover 14 of the housing 1 shown, or on the protective door base below the protective door 3, or on other structures of the housing 1.

[0058] like Figures 5-6 As shown, in a preferred embodiment of the protective door 3, the protective door 3 has a rectangular cross-section. Two protruding first sliders 32 and two protruding second sliders 33 are arranged opposite each other on the two side walls of the protective door 3 near the first slide rail 13. The direction of the line connecting the first sliders 32 and the second sliders 33 is consistent with the inclination direction of the first slide rail 13. The dimensions of the first sliders 32 and the second sliders 33 are matched with the dimensions of the first slide rail 13. The first sliders 32 and the second sliders 33 serve as sliding parts and slide in cooperation with the first slide rail 13, thereby allowing the protective door 3 to slide between a first position and a second position on the housing 1. This embodiment uses a structure where the first sliders 32 and the second sliders 33 cooperate with the first slide rail 13, making the protective door slide stably within the first slide rail 13. Obviously, at least three pairs of sliders or a single elongated slider can also be arranged opposite each other on the two side walls of the protective door 3 near the first slide rail 13, the slider being used for sliding cooperation with the first slide rail 13. As a less desirable embodiment, the protective door 3 can also be circular or other polygonal.

[0059] Preferably, the top side of the protective door 3 near the first through hole 11 and the through hole 22 is a flat surface. When the protective door 3 is in the first position, the flat surface of the top side is in close contact with the sealing member 2 and blocks the through hole 22. As another embodiment, the protective door 3 may also be provided with a corresponding receiving groove. When the protective door 3 is in the first position, the sealing member 2 is placed in the receiving groove, and the bottom of the receiving groove is in close contact with the sealing member 2, further increasing the sealing performance.

[0060] Preferably, the first slider 32 and the second slider 33 are cylinders. Of course, as a less desirable embodiment, the sidewalls of the first slider 32 and the second slider 33 can also be set as polygonal cubes with the same inclination angle as the first slide rail 13.

[0061] Preferably, the first slider 32 is provided with an annular sliding disk 34 around its peripheral wall. The annular sliding disk 34 is integrally formed with the protective door 3, and the annular sliding disk 34 slides in cooperation with the side wall of the housing 1 near the protective door 3. This embodiment uses an annular sliding disk 34 structure on the peripheral wall of the first slider 32, which allows the first slider 32 to slide more smoothly within the first slide rail 13, avoiding wear on the side wall of the protective door 3 during sliding. Of course, the first slider 32 may also omit the annular sliding disk 34.

[0062] Preferably, a first fixing post 12 is provided on the inner side of the housing 1 away from the first through hole 11, and a second fixing post 31 is provided on the side of the protective door 3 near the first fixing post 12. The elastic member 4 is sleeved on the first fixing post 12 and the second fixing post 31 and abuts against the housing 1 and the protective door 3, so that when the protective door 3 is in the first position, the protective door 3 is tightly fitted with the sealing member 2.

[0063] Furthermore, when the protective door 3 is in the first position, the second fixing post 31 is correspondingly arranged with the first fixing post 12; when the protective door 3 is in the second position, the second fixing post 31 and the first fixing post 12 are misaligned and the elastic component 4 is further compressed, and the pin 5 passes through the housing 1, so that when the pin 5 is pulled out, the protective door 3 can return from the first position to the second position, so that the protective door 3 and the sealing element 2 are tightly fitted. This embodiment adopts a matching structure of elastic component 4 and protective door 3, so that the protective door 3 can tightly fit with the sealing element 2 in the first position to prevent water from entering the socket, and the protective door 3 can quickly return to the first position when it is in the second position.

[0064] Further, the second fixed column 31 partially protrudes from the side wall of the protection door 3 away from the first through hole 11. In this embodiment, the second fixed column 31 partially protrudes from the protection door 3, so that the protection door 3 has a compact structure and is convenient for miniaturization design. Preferably, the second sliding block 33 partially protrudes from the side wall of the protection door 3 away from the first through hole 11, and the two sides of the protruding part of the second sliding block 33 are connected with the two connecting parts 35 of the protection door 3. In this embodiment, the second sliding block 33 partially protrudes from the protection door 3, and the protection door 3 is provided with the connecting part 35 structure, so that the protection door 3 has a compact structure, and the connection between the protection door 3 and the second sliding block 33 is more firm.

[0065] In a preferred embodiment of the protection door 3, the side of the protection door 3 away from the second fixed column 31 is an inclined surface, the inclined surface extends towards the first through hole 11 and extends towards the second fixed column 31, and the bolt 5 and the inclined surface are in sliding fit when the protection door 3 moves between the first position and the second position. Therefore, when the plug 5 is pulled out of the via hole 22, the protection door 3 immediately tightly fits with the sealing member 2.

[0066] The elastic component 4 in this embodiment is a compression spring. Obviously, it can also be a torsion spring, a leaf spring and other elastic components.

[0067] This embodiment also provides a socket, which comprises the waterproof socket protection door structure 10.
