Description

Technical Field

[0001] This utility model relates to the field of electrical accessories, specifically to a waterproof socket protection door structure. Background Technology

[0002] A wall socket, also known as a power outlet or switch socket, is a commonly used device in electrical connections. In outdoor environments, rainwater often seeps into wall sockets during rainy days, potentially causing internal short circuits. While many existing sockets use protective covers to prevent rainwater from entering, these covers can obstruct the insertion of the plug, and rainwater can still seep into the socket from the perimeter of the plug after insertion, affecting user experience and posing safety risks. Summary of the Invention

[0003] The purpose of this utility model is to overcome at least one defect of the prior art and provide a waterproof socket protection door structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This application provides a waterproof socket protection door structure, including a housing, a seal, a protection door, and an elastic component. The housing has a first through hole for a pin to pass through, and the seal includes an elastic sealing part placed in the first through hole. The elastic sealing part has a through hole for inserting a pin.

[0006] The protective door can move between a first position and a second position. The elastic component is connected to the protective door and drives the protective door to move from the second position to the first position. The protective door can move from the second position to the first position when subjected to force.

[0007] When the protective door is in the first position, the protective door blocks the through hole;

[0008] When the protective door is in the second position, the protective door is offset from the through hole, and the protective door releases its obstruction of the through hole.

[0009] Furthermore, when the protective door is in the first position, the elastic component drives the protective door to fit tightly against the sealing element and blocks the through hole. The force applied by the elastic component to the protective door has a component force opposite to the direction of the pin inserting into the first through hole.

[0010] Furthermore, the protective door slides along the first slide rail between a first position and a second position. The first slide rail is inclined relative to the direction in which the pin is inserted into the first through hole, so that when the protective door is in the first position, the elastic component drives the protective door to fit tightly against the sealing element.

[0011] Furthermore, the two sidewalls of the housing are provided with two first slides, which are inclined downwards away from the first through hole.

[0012] Furthermore, the first slide is an elongated hole that slopes downward and penetrates the side wall of the housing, and the protective door is provided with sliding parts on both sides that insert into the first slide; or, the first slide is an elongated groove that slopes downward, and the protective door is provided with sliding parts on both sides that insert into the first slide; or, the first slide is an elongated sliding rib, and the protective door 3 is provided with a sliding groove, which slides and engages with the elongated sliding rib.

[0013] Furthermore, the protective door is rotatably configured to rotate between a first position and a second position. The rotation axis of the protective door is perpendicular to the direction in which the pin is inserted into the first through hole, so that when the protective door is in the first position, the elastic component drives the protective door to fit tightly against the sealing element.

[0014] Furthermore, the size of the through hole is smaller than the size of the peripheral wall of the external pin, and when the pin is not inserted, the through hole has a gap or the through hole is closed.

[0015] Furthermore, the through hole of the elastic sealing part is provided with a protruding sealing flap to close the through hole.

[0016] Furthermore, the housing is provided with a first fixing post, and the protective door is provided with a second fixing post on the side near the first fixing post. The elastic component is sleeved on the first fixing post and the second fixing post.

[0017] Furthermore, the protective door has two protruding first sliders and two protruding second sliders arranged opposite each other on the two side walls near the first slide rail. The direction of the line connecting the first slider and the second slider is consistent with the inclination direction of the first slide rail, and the first slider and the second slider slide in cooperation with the first slide rail.

[0018] Furthermore, the first slider is provided with an annular sliding disk around its peripheral wall. The annular sliding disk is integrally formed with the protective door, and the annular sliding disk slides in cooperation with the side wall of the housing near the protective door.

[0019] Furthermore, when the protective door is in the first position, the second fixing post is correspondingly arranged with the first fixing post; when the protective door is in the second position, the second fixing post is misaligned with the first fixing post.

[0020] Furthermore, the sealing element includes an elastic sealing portion and a second sealing portion connected to the elastic sealing portion. The second sealing portion is elastic and is tightly fitted to the side of the top wall of the housing near the protective door. When the protective door is in the first position, the elastic component drives the protective door to fit tightly against the second sealing portion.

[0021] Furthermore, the sealing element includes an integrally formed first sealing part, an elastic sealing part, and a second sealing part connected in sequence. The first sealing part, the elastic sealing part, and the second sealing part are all elastic. The first sealing part is tightly fitted and connected to the side of the top wall of the housing away from the protective door.

[0022] Furthermore, the dimensions of the first sealing portion and the second sealing portion are larger than the dimensions of the elastic sealing portion, and the first sealing portion and the second sealing portion completely cover the first through hole.

[0023] This application also provides a socket, including the waterproof socket protection door structure described in any of the above claims.

[0024] Furthermore, the socket includes a base and a panel, with the base and panel arranged opposite to each other. The base is provided with an L-pole sleeve, an N-pole sleeve, and an E-pole sleeve, and the panel is provided with corresponding L-pole holes, N-pole holes, and E-pole holes. The housing of the waterproof socket protective door structure includes a top cover, which is provided with the first through hole. The top cover covers the E-pole sleeve mounting groove, and a sealing element is installed on the top cover. The protective door and the elastic component are located between the E-pole sleeve mounting groove and the top cover.

[0025] The waterproof socket protection door structure of this utility model adopts a matching structure of elastic sealing part and first through hole, and a structure of protection door covering the through hole, which can prevent external rainwater from entering the socket and causing short circuit risk. Moreover, the structure is simple and easy to install.

[0026] Furthermore, in the waterproof socket protection door structure of this utility model, when the protection door is in the first position, the elastic component drives the protection door to fit tightly against the sealing element and block the through hole, thus preventing external rainwater from entering the socket whether the socket is plugged in or not.

[0027] In addition, the sealing element of the waterproof socket protection door structure of this utility model adopts a through-hole closure or a through-hole gap and external pin matching structure to prevent rainwater from flowing into the socket through the through-hole.

[0028] Furthermore, the waterproof socket protection door structure of this utility model adopts a first sliding track inclined structure, which slides in conjunction with the protection door. Thus, when the protection door is in the first position, the protection door applies force to the sealing element, resulting in a better seal; when the protection door can move from the second position to the first position, the sliding of the protection door towards the sealing element is more stable.

[0029] Furthermore, the waterproof socket protective door structure of this utility model employs a mating structure between the first and second sealing parts of the sealing element and the housing, making it more difficult for external rainwater to enter the socket. Moreover, the sealing element is fixed in place, with the elastic sealing part positioned within the first through hole, preventing the sealing element from falling off and improving reliability. In particular, when the protective door is in the first position, the elastic component drives the protective door to fit tightly against the second sealing part. The protective door can slightly compress the elastic second sealing part, further hindering external rainwater from entering the socket, thus providing a rainproof function.

[0045] 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.

[0046] 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 circuit, and the other end is used to connect the plug. The sleeve has a clamping effect and can cooperate with the plug pin 5 to achieve clamping connection, which can fix and limit the plug.

[0047] The protective door structure is a waterproof socket protective door structure 10, which can prevent external rainwater from entering the socket, whether the pin 5 is inserted or not.

[0048] like Figure 1-3 As shown, this embodiment provides a waterproof socket protection door structure, including a housing 1, a sealing element 2, a protection door 3, and an elastic component 4. The housing 1 is provided with a first through hole 11 for a pin 5 to pass through. The sealing element 2 includes an elastic sealing part 24 placed in the first through hole 11. The elastic sealing part 24 is provided with a through hole 22 for inserting the pin 5.

[0049] 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.

[0050] When the protective door 3 is in the first position, the protective door 3 blocks the through hole 22;

[0051] When the protective door 3 is in the second position, the protective door 3 is offset from the through hole 22, the protective door 3 releases its obstruction of the through hole 22, the pin 5 passes through the through hole 22, and the through hole 22 is tightly fitted with the periphery of the pin 5; when the pin 5 is pulled out of the through hole 22, the protective door 3 returns to the first position from the second position, blocking the through hole 22.

[0052] In this embodiment, the waterproof socket protection door structure 10 adopts a structure in which the elastic sealing part 24 and the first through hole 11 cooperate, and the protection door 3 blocks the through hole 22. This can prevent external rainwater from entering the socket and causing a short circuit risk. Moreover, the structure is simple and easy to install.

[0053] like Figure 1-3 As shown, in a preferred embodiment of the waterproof socket protection door structure 10, the waterproof socket protection door structure 10 includes a housing 1, a sealing member 2 disposed on 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; a first through hole 11 is provided on the top wall of the housing 1, and the elastic sealing part 24 of the sealing member 2 is placed in the first through hole 11 and tightly fitted with the first through hole 11, thereby preventing external rainwater from entering the socket through the first through hole 11. An elastic member 4 is provided between the housing 1 and the protective door 3. When the protective door 3 is in the first position, the elastic member 4 applies force to the protective door 3, making the protective door 3 tightly fit with the sealing member 2 and block the through hole 22. When the pin 5 is inserted into the through hole 22, it applies force to the protective door 3, compressing the elastic member 4 and moving the protective door 3 away from the first through hole 11, that is, moving to the second position, where the pin 5 can be inserted into the socket sleeve. When the pin 5 is pulled out of the through hole 22, the elastic member 4 drives the protective door 3 to move towards the first through hole 11, that is, back to the first position. After the protective door 3 returns to the first position, it tightly fits with the sealing member 2, preventing rainwater from entering the socket. In this embodiment, the waterproof socket protective door structure 10, based on the cooperation structure of the elastic sealing part 24 and the first through hole 11, further improves the structure by making the protective door 3 tightly fit with the sealing member 2 and block the through hole 22. Whether the pin 5 is inserted or not, it can prevent external rainwater from entering the socket. Thus, the waterproof socket of this embodiment can be used outdoors without installing a protective cover to prevent rainwater or other water from entering the socket. Of course, a protective cover can also be installed.

[0054] like Figure 2-4As shown, in a preferred embodiment of the sealing element 2, the sealing element 2 is elastic in its entirety and is made of silicone, rubber, or the like. The size of the through hole 22 of the elastic sealing part 24 is smaller than the size of the peripheral wall of the pin 5. The elastic sealing part 24 is placed inside the first through hole 11, reducing the space of the first through hole 11 or sealing the first through hole 11. 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 squeezes the elastic sealing part 24 to open the through hole 22. The sealing element 2 fits tightly with the peripheral wall of the pin 5, preventing rainwater 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 elastic sealing part 24 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 squeezes the elastic sealing part 24 to open the through hole 22. The sealing member 2 fits tightly with the peripheral wall of the pin 5 to prevent rainwater 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. The sealing member of the waterproof socket protection door structure of this utility model adopts a through hole closure or a through hole gap and external pin cooperation structure to prevent rainwater from flowing into the socket from the through hole.

[0055] Specifically, 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, and blocks the through hole 22, further preventing water from entering the socket through the first through hole. The force applied by the elastic component 4 to the protective door 3 has a component force opposite to the direction of the pin 5 inserting into the first through hole 11, making the protective door 3 fit tightly against the sealing element 2, sealing the first through hole 11, and preventing water from entering the socket. 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 member 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. As another degraded embodiment, when the through hole 22 is closed when the pin 5 is not inserted, the protective door 3 may not fit tightly against the sealing member 2, for example, the protective door 3 may be set to slide in a horizontal direction.

[0056] Preferred, such as Figure 4In the preferred embodiment shown, the sealing element 2 includes an integrally formed first sealing part 23, an elastic sealing part 24, and a second sealing part 25 connected in sequence. All three parts are elastic. The first sealing part 23 is tightly fitted to the side of the top wall of the housing 1 away from the protective door 3. The elastic sealing part 24 is tightly fitted to the first through hole 11. The second sealing part 25 is tightly fitted to the side of the top wall of the housing 1 near the protective door 3. This embodiment employs a fitting structure between the first sealing part 23 and the second sealing part 25 of the sealing element 2 and the top wall of the housing 1, making it more difficult for external rainwater to enter the socket. Furthermore, by fixing the sealing element 2 in place, the elastic sealing part 24 is positioned within the first through hole 11, preventing the sealing element 2 from falling off and improving reliability. In particular, when the protective door 3 is in the first position, the elastic component 4 drives the protective door 3 to fit tightly against the second sealing part 25. The protective door 3 can slightly compress the elastic second sealing part 25, further reducing the likelihood of external rainwater entering the socket and providing a rainproof function.

[0057] Furthermore, the dimensions of the first sealing portion 23 and the second sealing portion 25 are larger than the dimensions of the elastic sealing portion 24, so that the first sealing portion 23 and the second sealing portion 25 completely cover the first through hole 11.

[0058] Preferably, the first sealing part 23 and the second sealing part 25 are sealed to the top wall of the housing 1 by means of water-proof grease, and the elastic sealing part 24 is sealed to the first through hole 11 by means of water-proof grease.

[0059] Furthermore, the first sealing part 23, the elastic sealing part 24, and the second sealing part 25 all have square or flat cross-sections, and the through hole 22 passes through the first sealing part 23, the elastic sealing part 24, and the second sealing part 25. Of course, the cross-sectional shape of the first sealing part 23, the elastic sealing part 24, and the second sealing part 25 can also be circular or other polygonal.

[0060] Furthermore, the dimension of the long side of the second sealing portion 25 is larger than the dimension of the corresponding side of the first sealing portion 23. Of course, the dimension of the long side of the second sealing portion 25 may also be smaller than or equal to the dimension of the corresponding side of the first sealing portion 23.

[0061] It should be noted that, as a deteriorated embodiment, the first sealing part 23 and / or the second sealing part 25 may not be provided, and in particular, the first sealing part 23 may not be provided.

[0062] In a less desirable embodiment of the seal 2, the seal 2 includes a first sealing cap and a second sealing cap that fits into it. The first and second sealing caps are made of rigid material and fit tightly against the two sides of the top wall of the housing 1, respectively. A second connecting portion and a third connecting portion are disposed opposite to the first sealing cap and the second sealing cap. The shapes of the second and third connecting portions are configured to fit the first through hole 11. An elastic sealing portion 24 is provided between the second and third connecting portions. The elastic sealing portion 24 has a through hole for the pin 5 to pass through. While the second and third connecting portions are made of rigid material and the structure of the elastic sealing portion 24 can achieve a waterproof effect, the overall waterproof effect is somewhat worse than that of a single, elastic seal 2.

[0063] In a less desirable embodiment of the seal 2, the elastic sealing portion 24 is flat and has a through hole 22 for the pin 5 to pass through. The housing 1 has two annular flanges arranged inwardly around the first through hole 1, with the elastic sealing portion 24 positioned between them. The elastic sealing portion 24 fits tightly with the first through hole 11 and the two annular flanges. This structure can achieve waterproofing, but it requires high installation precision and is difficult to manufacture.

[0064] like Figure 1 and 7 As shown, in a preferred embodiment of the first slide rail 13, the housing 1 includes a top cover 14. Two first slide rails 13 are arranged opposite each other on the two side walls of the top cover 14. The first slide rails 13 are inclined downwards away from the first through hole 11. The protective door 3 has sliding portions on both sides that insert into the first slide rails 13. The sliding portions of the protective door 3 slide within the first slide rails 13, thereby allowing the protective door 3 to apply an upward force to the sealing member 2. When the protective door 3 slides from the second position to the first position, it slides back to the first position towards the first through hole 11 and tightly engages with the sealing member 2. This embodiment employs an inclined structure for the first slide rail 13, which slides in cooperation with the protective door 3. Therefore, when the protective door 3 is in the first position, it applies force to the sealing member 2, resulting in a better seal; when the protective door 3 can move from the second position to the first position, its sliding towards the sealing member is more stable.

[0065] Preferably, the first slide rail 13 is an elongated, downward-sloping hole that penetrates the side wall of the upper cover 14, and the sliding part slides within the first slide rail 13. That is, with Figure 7Taking the indicated direction as a reference, the first slide rail 13 extends away from the first through hole 11 in both the horizontal and vertical directions. Preferably, the first slide rail 13 is an elongated groove sloping downwards, and the sliding part slides within the first slide rail 13. That is, with Figure 7 Taking the indicated direction as a reference, the first slide 13 extends away from the first through hole 11 in both the horizontal and vertical directions. The elongated groove can be formed by slotting on the side wall of the upper cover 14, or it can be formed between the parallel sliding ribs on the upper cover 14.

[0066] In other embodiments, the first slide rail 13 may also be an inclined elongated sliding rib, and the protective door 3 is provided with a sliding groove, which is slidably fitted onto the elongated sliding rib.

[0067] Of course, the protective door structure may also omit the first slide rail 13. The protective door 3 is 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. 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 containing the first through hole 11, but perpendicular to the plane containing the first through hole 11.

[0068] Specifically, one end of the protective door 3 is connected to the upper cover 14 via an elastic member 4, and the end of the protective door 3 away from the elastic member 4 is rotatably connected to a rotating part provided on the upper cover 14. Thus, when the protective door 3 is in the first position, the elastic member 4 applies a rotational force to the protective door 3, causing the protective door 3 to fit tightly with the sealing member 2, 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, i.e., the protective door 3 is in the second position. When the pin 5 is pulled out of the through hole 22, the elastic member 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.

[0069] It should be noted that the first slide rail 13 may not be installed on the upper cover 14 of the housing 1, but may be installed on the protective door base below the protective door, or on other structures of the housing 1.

[0070] like Figure 5-6As shown, in a preferred embodiment of the protective door 3, the protective door 3 has a square 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. 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 sliders 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.

[0071] 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.

[0072] Preferably, the first slider 32 is provided with an annular sliding plate 34 around its peripheral wall. The annular sliding plate 34 is integrally formed with the protective door 3, and the annular sliding plate 34 slides in cooperation with the side wall of the upper cover 14 near the protective door 3. This embodiment uses an annular sliding plate 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 plate 34.

[0073] Preferably, an elastic member 4 is provided between the housing 1 and the protective door 3, and the elastic member 4 drives the protective door 3 to slide between a first position and a second position within the housing 1. 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.

[0074] 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; the pin 5 passes through the first through hole 11 and through hole 22 to push the protective door 3 to compress the elastic component 4, causing the protective door 3 to move from the first position to the second position. When the protective door 3 is in the second position, the second fixing post 31 and the first fixing post 12 are misaligned. 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 component 2 are tightly fitted. This embodiment adopts a matching structure of the elastic component 4 and the protective door 3, so that the protective door 3 can tightly fit with the sealing component 2 in the first position to prevent external rainwater from entering the socket, and the protective door 3 can quickly return to the first position when it is in the second position.

[0075] Furthermore, the second fixing post 31 protrudes from the side wall of the protective door 3 away from the first through hole 11. In this embodiment, the second fixing post 31 protrudes from the protective door 3, making the protective door 3 compact and facilitating miniaturization design.

[0076] Preferably, the second slider 33 protrudes from the side wall of the protective door 3 away from the first through hole 11, and the two sides of the protruding part of the second slider 33 are connected to the two connecting parts 35 of the protective door 3. In this embodiment, the second slider 33 protrudes from the protective door 3, and the connecting parts 35 structure of the protective door 3 makes the structure of the protective door 3 compact, and makes the connection between the protective door 3 and the second slider 33 more secure.

[0077] In a preferred embodiment of the protective door 3, the side of the protective door 3 away from the second fixing post 31 is an inclined surface. The inclined surface extends towards the first through hole 11 and towards the second fixing post 31. When the protective door 3 moves between the first position and the second position, the pin 5 slides into the inclined surface. Thus, when the pin 5 is pulled out of the through hole 22, the protective door 3 immediately and tightly engages with the sealing element 2.

[0078] like Figure 7-8 As shown, the housing 1 includes a top cover 14. In a preferred embodiment, the top cover 14 is a hollow structure with an opening at one end and a square cross-section. The top cover 14 has a square first through hole 11 for tight fitting with the sealing element 2. Of course, the first through hole 11 can also be circular or other polygonal structures.

[0079] In this embodiment, the elastic component 4 is a compression spring. Obviously, it could also be a torsion spring, leaf spring, or other elastic component.

[0080] This embodiment also provides a socket, which includes the aforementioned waterproof socket protection door structure 10.
