Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a protective door structure for a socket and a socket. Background Technology

[0002] Traditional socket safety shutters typically have a beveled drive surface, creating a gap between the front of the safety shutter and the socket hole. During home renovations and socket use, dust and foreign objects can fall into the socket through this gap, causing the safety shutter to malfunction and become unable to open, preventing the plug from being inserted and affecting user experience. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a protective door structure and socket with dustproof effect.

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

[0005] In a first aspect, this application provides a protective door structure for a socket, including a protective door, at least one elastic element, and a first through hole. The protective door includes a planar upper surface. The protective door slides back and forth between a first position and a second position along a strip-shaped slide rail. The strip-shaped slide rail is inclined, and the inclination direction of the strip-shaped slide rail intersects with the direction in which the pin is inserted into the pin hole. The included angle of the intersection is an obtuse angle or an acute angle. When at least one of the elastic elements drives the protective door to slide to the first position, the upper surface is tightly fitted with the plane where the first through hole is located and blocks the first through hole. When the protective door slides to the second position after being subjected to external force and overcoming the elastic force of the elastic element, the upper surface separates from the plane where the first through hole is located, the protective door is misaligned with the first through hole, and the protective door releases its obstruction of the first through hole.

[0009] In one possible implementation, the protective door mounting component further includes a planar upper top wall, which is bent and connected to the second side wall and the fourth side wall respectively. The first through hole is formed in the upper top wall. When the elastic element drives the protective door to slide to the first position, the side of the upper top wall relative to the protective door is tightly fitted with the upper surface of the protective door and blocks the first through hole.

[0010] In one possible implementation, the protective door mounting component further includes a first sidewall and a third sidewall disposed opposite to each other, the first sidewall being bent and connected to the upper top wall, the second sidewall and the fourth sidewall respectively, the third sidewall being bent and connected to the upper top wall, the second sidewall and the fourth sidewall respectively, the elastic element being installed between the first sidewall and the protective door, and / or the elastic element being installed between the third sidewall and the protective door.

[0011] In one possible implementation, the protective door includes opposing left and right sides, opposing front and rear sides, and a lower surface opposing the upper surface. The left side faces the first sidewall, and the right side faces the third sidewall. The front and rear sides are respectively provided with the sliding boss.

[0012] The first sidewall and the left side are respectively provided with a first mounting boss, and the two ends of an elastic element are respectively connected to the two first mounting bosses, and / or the third sidewall and the right side are respectively provided with a second mounting boss, and the two ends of an elastic element are respectively connected to the two second mounting bosses.

[0013] In one possible implementation, the strip rail includes a strip sliding groove or a strip sliding hole.

[0014] In one possible implementation, the sliding boss comprises two bosses spaced apart.

[0015] In one possible implementation, the sliding boss comprises a strip-shaped sliding post.

[0016] In one possible implementation, at least one of the bosses has a sliding protrusion at its bottom.

[0017] In one possible implementation, a sliding protrusion is provided at the bottom of the strip-shaped sliding column.

[0018] In one possible implementation, the sliding boss includes a first protrusion that protrudes from the lower surface of the protective door, and a first connecting portion is included between the lower surface and the first protrusion.

[0019] In one possible implementation, the first mounting boss on the left side of the protective door includes a second protrusion.

[0020] Secondly, this application provides a socket with a protective door structure including the socket described above.

[0021] In one possible implementation, the socket includes a socket cover and a socket base. The socket base is provided with an L-pole clamping arm, an N-pole clamping arm, and an E-pole clamping arm. The socket cover is provided with an L-pole pin hole, an N-pole pin hole, and an E-pole pin hole. The socket base includes an E-pole protective door receiving cavity. A protective door structure is disposed within the E-pole protective door receiving cavity. The socket cover is closed onto the socket base. The protective door structure is located between the E-pole clamping arm and the E-pole pin hole.

[0022] Compared to existing technologies, the protective door structure of this utility model includes a door, at least one elastic element, and a first through hole. The protective door includes a planar upper surface. The protective door slides back and forth between a first position and a second position along a strip-shaped slide rail. The strip-shaped slide rail is inclined, and its inclination direction intersects the direction in which the pin is inserted into the pin hole. The angle of intersection is an obtuse angle or an acute angle. When at least one of the elastic elements drives the protective door to slide to the first position, the upper surface is tightly fitted with the plane of the first through hole and blocks the first through hole. After the protective door is subjected to external force... When the elastic force of the elastic element is overcome and the device slides to the second position, the upper surface separates from the plane where the first through hole is located, the protective door is misaligned with the first through hole, and the protective door releases its obstruction of the first through hole. When the protective door is in the first position, the upper surface of the protective door planar structure is tightly fitted with the plane where the first through hole is located and completely blocks the first through hole. This can prevent dust and foreign objects from entering the socket through the gap between the protective door and the first through hole, which would cause the protective door of the socket to move poorly and affect the normal use of the protective door. This utility model can play a very good role in dust prevention.

[0023] Furthermore, two protrusions or one strip-shaped sliding column are respectively provided on both sides of the protective door. The second and fourth side walls of the protective door mounting component are respectively provided with strip-shaped slide rails at an angle. The two protrusions are installed in the strip-shaped slide rails or the strip-shaped sliding column is installed in the strip-shaped slide rails. The structural design of providing two protrusions or one strip-shaped sliding column on both sides of the protective door can make the protective door slide smoothly and prevent the protective door from rotating.

[0024] Furthermore, the protective door structure described in this application is a modular structure, which can be flexibly installed in at least one pole of the socket, facilitating installation, disassembly, and management. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] like Figures 1-7As shown, the socket includes a socket housing with at least one set of plug holes and at least one set of socket sleeves inside the socket housing. Each plug hole includes at least one pin hole, and each socket sleeve includes at least one clamping arm. The pin hole and the clamping arm are positioned correspondingly. A pin on the plug passes through the pin hole on the socket and connects to the clamping arm, allowing electrical equipment to be connected to the power supply. The socket also has a protective door structure inside, comprising a protective door 1, at least one elastic element 2, and a first through-hole 32. The protective door 1 includes a planar upper surface 11, and the protective door 1 extends along a strip-shaped slide rail 4 on a first... The protective door 1 slides back and forth between the first and second positions. The strip-shaped slide rail 4 is inclined, and the inclination direction of the strip-shaped slide rail 4 intersects the direction in which the pin is inserted into the pin hole. The included angle of intersection is an obtuse angle or an acute angle. When at least one of the elastic elements 2 drives the protective door 1 to slide to the first position, the upper surface 11 is tightly fitted with the plane where the first through hole 32 is located and blocks the first through hole 32. When the protective door 1 is subjected to external force and slides to the second position against the elastic force of the elastic element 2, the upper surface 11 separates from the plane where the first through hole 32 is located, the protective door 1 is misaligned with the first through hole 32, and the protective door 1 releases its obstruction of the first through hole 32. The elastic element 2 can be a compression spring, tension spring, torsion spring, or spring, etc.

[0035] like Figure 1 As shown, the upper surface 11 of the protective door 1 is a planar structure, which is closely fitted to and blocks the first through hole 32. This can prevent dust from accumulating between the pin hole and the protective door 1, or prevent dust from entering the socket. It can play a very good dustproof role. The protective door 1 slides back and forth between the first position and the second position along the inclined strip rail 4 to block or offset the first through hole 32. When the socket is not in use, it can block the pin hole to prevent small foreign objects from entering the socket from the gap between the first through hole 32 and the protective door 1, which would cause the protective door 1 to move poorly or to be unable to open, thus affecting the use of the protective door 1. This utility model can play a very good dustproof role.

[0036] To make it easier to understand, Figure 1 The thickness direction of the protective door mounting component 3 is defined as the second direction D2, and the length direction of the protective door mounting component 3 is defined as the first direction D1. The first direction D1 is perpendicular to the second direction D2.

[0037] Preferred, such as Figures 1-3As shown, the strip-shaped slide rail 4 includes a first strip-shaped sidewall 41 and a second strip-shaped sidewall 42 arranged parallel to each other and opposite to each other. The lengths of both the first strip-shaped sidewall 41 and the second strip-shaped sidewall 42 are greater than the distance between the first strip-shaped sidewall 41 and the second strip-shaped sidewall 42. The protective door 1 slides back and forth between a first position and a second position along an inclined straight line parallel to the first strip-shaped sidewall. The protective door 1 always and simultaneously generates displacement in the first direction D1 and the second direction D2.

[0038] Specifically, such as Figure 2 and Figure 3 As shown in the embodiment of this application, when the elastic element 2 drives the protective door 1 to slide from the second position to the first position, the protective door 1 experiences a rightward displacement in the first direction D1 and an upward displacement in the second direction D2. When the protective door 1 is subjected to an external force and slides from the first position to the second position, the protective door 1 experiences a leftward displacement in the first direction D1 and a downward displacement in the second direction D2. Figure 1 An exploded view of the door structure protected by this application is shown. Figure 2 A cross-sectional view of the protective door structure is shown when the protective door 1 is in the first position. Figure 3 A cross-sectional view of the protective door structure is shown when the latch is inserted into the latch hole, placing the protective door 1 in the second position. Figure 2 and Figure 3 It is a sectional view of the protective door structure after being cut along the plane containing the first direction D1 and the second direction D2.

[0039] Furthermore, such as Figure 2 As shown, when the protective door 1 is in the first position, the elastic force direction of the elastic member 2 is tilted. The elastic member 2 has both a rightward elastic force along the first direction D1 and an upward elastic force along the second direction D2. When the protective door 1 is in the closed state, the tilted setting of the elastic member 2 can make the protective door 1 have a better closing effect.

[0040] Preferably, the protective door structure includes two oppositely arranged strip slide rails 4, and two sliding protrusions 5 extending from both sides of the protective door 1. The protective door 1 is located between the two strip slide rails 4, and the two sliding protrusions 5 are respectively installed in the two strip slide rails 4.

[0041] Furthermore, such as Figures 4-6 As shown, the protective door structure also includes a protective door mounting component 3. The protective door 1 is slidably installed in the protective door mounting component 3. The protective door mounting component 3 includes a second side wall 33 and a fourth side wall 34 opposite to each other. The protective door 1 is slidably installed between the second side wall 33 and the fourth side wall 34. The second side wall 33 and the fourth side wall 34 are respectively provided with the strip-shaped slide rail 4. Two sliding bosses 5 extend from both sides of the protective door 1. The two sliding bosses 5 are respectively installed in the two strip-shaped slide rails 4.

[0042] Furthermore, such as Figure 1 and Figure 4 As shown, the protective door mounting component 3 also includes a planar upper top wall 31, which is bent and connected to the second side wall 33 and the fourth side wall 34 respectively. The first through hole 32 is opened in the upper top wall 31. When the elastic member 2 drives the protective door 1 to slide to the first position, the side of the upper top wall 31 relative to the protective door 1 is tightly fitted with the upper surface 11 of the protective door 1 and blocks the first through hole 32.

[0043] Furthermore, in one embodiment, the protective door mounting component 3 does not include the upper top wall 31, the first through hole 32 is a pin hole of the plug hole, when the protective door 1 is in the first position, the elastic member 2 drives the protective door 1 so that the upper surface 11 and the pin hole are tightly fitted together on the plane to cover the pin hole.

[0044] Furthermore, such as Figure 4 As shown, the elastic element 2 is connected between the protective door 1 and the protective door mounting component 3. The protective door mounting component 3 further includes a first side wall 35 and a third side wall 36 disposed opposite to each other. The first side wall 35 is bent and connected to the upper top wall 31, the second side wall 33, and the fourth side wall 34, respectively. The third side wall 36 is bent and connected to the upper top wall 31, the second side wall 33, and the fourth side wall 34, respectively. The elastic element 2 is installed between the first side wall 35 and the protective door 1, and / or, the elastic element 2 is installed between the third side wall 36 and the protective door 1. When the elastic element 2 is installed between the first side wall 35 and the protective door 1, the elastic element 2 is preferably a compression spring; when the elastic element 2 is installed between the third side wall 36 and the protective door 1, the elastic element 2 is preferably a tension spring. Figure 4 This is a schematic diagram of the structure of the protective door mounting component 3 in one embodiment of this application. The protective door 1 and the elastic member 2 are installed inside the protective door mounting component 3 to form a modular protective door structure. The protective door structure is installed inside the socket housing and can be flexibly installed in at least one pole of the socket, which is convenient for installation, disassembly and management.

[0045] Furthermore, such as Figure 1 As shown, the protective door 1 has a structure similar to a cuboid or cube, including a left and right side facing away from each other, a front and rear side facing away from each other, and a lower surface facing away from the upper surface 11. The left side faces the first sidewall 35, and the right side faces the third sidewall 36. The front and rear sides are respectively provided with sliding bosses 5.

[0046] The first sidewall 35 and the left side are respectively provided with a first mounting boss 21, and the two ends of an elastic element 2 are respectively connected to the two first mounting bosses 21, and / or, the third sidewall 36 and the right side are respectively provided with a second mounting boss, and the two ends of an elastic element 2 are respectively connected to the two second mounting bosses. Figures 1-3 As shown in this embodiment, the elastic element 2 is a compression spring, which is disposed between the first sidewall 35 and the left side surface. One end of the compression spring is connected to the first mounting boss 21 on the first sidewall 35, and the other end is connected to the first mounting boss 21 on the left side surface.

[0047] Preferably, the strip-shaped slide rail 4 includes a strip-shaped sliding groove or a strip-shaped sliding hole. For example, Figure 1 and Figure 4 As shown in the embodiment of this application, the strip-shaped slide rail 4 is a strip-shaped sliding hole.

[0048] Preferred, such as Figure 5 As shown, in one embodiment, the sliding boss 5 includes two bosses 51 spaced apart, and at least one of the bosses 51 has a sliding protrusion 52 at its bottom; as Figure 6 As shown, in another embodiment, the sliding boss 5 includes a strip-shaped sliding post 53, and a sliding protrusion 52 is provided at the bottom of the strip-shaped sliding post 53.

[0049] The installation of two protrusions 51 or one strip-shaped sliding column 53 in the strip-shaped slide rail 4 can make the protective door 1 slide smoothly in the strip-shaped slide rail 4. The use of two protrusions 51 avoids the situation where the protective door 1 rotates due to one protrusion 51. The sliding protrusion 52 contacts the second side wall 33 and the fourth side wall 34, which can reduce the contact area between the protective door 1 and the protective door mounting part 3 and increase the smoothness of the sliding of the protective door 1.

[0050] Furthermore, such as Figure 5 and Figure 6 As shown, the sliding boss 5 includes a first protrusion 54, which protrudes from the lower surface of the protective door 1. A first connecting part 55 is included between the lower surface and the first protrusion 54, which can reduce the distance between the upper surface 11 and the lower surface of the protective door 1 and reduce the thickness of the protective door 1.

[0051] Furthermore, such as Figure 5 and Figure 6 As shown, the lower surface of the protective door 1 and the first protrusion 54 include a first connecting part 55. While reducing the thickness of the protective door 1, the first connecting part 55 can increase the connection thickness between the sliding boss 5 and the protective door 1, and increase the structural strength of the sliding boss 5.

[0052] Furthermore, such as Figure 5As shown, after reducing the thickness of the protective door 1, the first mounting boss 21 on the left side of the protective door 1 includes a second protrusion 22, which does not affect the installation of the elastic element 2. In a preferred embodiment, the second protrusion 22 may further include a second connecting portion (not shown in the figure), which can increase the connection thickness between the second protrusion 22 and the lower surface of the protective door 1, thereby enhancing the structural strength of the second protrusion 22.

[0053] In this embodiment, the protective door structure is applied to a single pole of the socket (in this embodiment, it is set to the E pole). Specifically, the protective door structure includes an upper top wall 31, on which the first through hole 32 is formed. After the protective door structure is installed inside the socket, the first through hole 32 corresponds to a pin hole. When the protective door 1 of the protective door structure is in the first position, the protective door 1 is blocked between the first through hole 32 and a clamping arm. When the socket is not in use, the protective door structure can block the pin hole on the socket to prevent small foreign objects from entering the socket and improve the safety of the socket.

[0054] Alternatively, in other embodiments, the protective door mounting component 3 does not include the upper top wall 31, and the upper surface 11 of the protective door 1 is in close contact with the plane where the pin hole is located to prevent dust from entering and play a dustproof role.

[0055] Preferred, such as Figure 7 As shown, the socket housing includes a socket cover (not shown in the figure) and a socket base 6. The socket base 6 is provided with at least one set of socket sleeves. The socket cover is provided with at least one set of plug holes. The at least one set of plug holes corresponds to the position of at least one set of socket sleeves. The socket base 6 is also provided with at least one protective door receiving cavity 61. At least one protective door structure is installed in at least one protective door receiving cavity 61. The socket cover is closed on the socket base 6. The protective door structure is located between the socket sleeves and the socket cover and between a clamping arm and a pin hole. In this embodiment, the socket is a three-hole socket, including an L-pole, an N-pole, and an E-pole. The socket base 6 is provided with an L-pole clamping arm, an N-pole clamping arm, and an E-pole clamping arm. The socket cover is provided with an L-pole pin hole, an N-pole pin hole, and an E-pole pin hole. The socket base 6 is provided with an E-pole protective door receiving cavity 61. The protective door structure is installed within the E-pole protective door receiving cavity 61, located between the E-pole clamping arm and the E-pole pin hole, effectively preventing fingers or conductive objects from accidentally inserting into the ground electrode hole. The ground electrode is usually connected to the earth in a circuit. If a person directly touches a live ground electrode, a current path may be formed, leading to an electric shock accident. Especially for children, they may be more likely to try to insert small objects into the socket hole out of curiosity; therefore, the protective door 1 can greatly reduce this risk. Figure 7 A schematic diagram of the structure of the socket base 6 of this application is shown.

[0056] Furthermore, such as Figure 7 As shown in the preferred embodiment of this application, a protective door structure is provided inside the socket. The protective door structure is installed on the E pole of the socket to block the ground pin hole. Of course, in other embodiments, the protective door structure can also be installed on the L pole of the socket to block the L pole pin hole, or installed on the N pole of the socket to block the N pole pin hole.

[0057] Furthermore, the socket includes two sockets, and at least one of the aforementioned protective door structures is provided inside the socket, with the protective door structure installed on at least one of the L and N poles of the socket; and / or, the socket includes three sockets, and at least one of the aforementioned protective door structures is provided inside the socket, with the protective door structure installed on at least one of the L, N, and E poles of the socket; and / or, the socket includes four sockets, and at least one of the aforementioned protective door structures is provided inside the socket, with the protective door structure installed on at least one of the L1, L2, L3, and N poles of the socket.
