Embodiments of the first aspect

An embodiment of the present invention provides a security door for a socket, and fig. 1 is a schematic view of the security door according to the embodiment of the present invention. As shown in fig. 1, the security gate 1 includes: a base 11, a slide 12 and a support bar 13.

The base 11 includes a first bottom portion 111 and a first wall portion 112. The first wall portion 112 extends from the first bottom portion 111 in the up-down direction perpendicular to the first bottom portion 111, for example, the first wall portion 112 may extend upward. The first wall 112 has a first through hole 1121 and a second through hole 1122 that are provided to face each other.

The slider 12 is disposed inside a space surrounded by the first bottom portion 111 and the first wall portion 112 of the base 11. The slider 12 includes a body portion 121, and the body portion 121 has a passage 1211 extending through the body portion 121.

The support rod 13 is inserted through the first through hole 1121, the passage 1211, and the second through hole 1122, and supports the slider 12 to slide along the support rod 13 in a sliding direction parallel to the longitudinal direction of the support rod 13.

According to the above embodiment, the support rod 13 penetrating the slider 12 is used as a guide mechanism to guide the slider 12 to slide in the sliding direction, so that the friction force between the slider 12 and the guide mechanism can be reduced, and the reliability of the sliding of the slider 12 can be improved; further, since the support rod 13 penetrates the slider 12, the slider 12 can be prevented from deviating from the sliding direction, and the stability of the sliding of the slider 12 can be improved.

In at least one embodiment, the security gate 1 may be applied to any type of receptacle. For example, as shown in fig. 1, the safety door 1 may be a two-hole receptacle safety door. Alternatively, the security gate 1 may be a security gate of a three-hole socket or other socket. Hereinafter, the structure of the safety door will be described by way of example using a safety door with a two-hole receptacle.

In at least one embodiment, the support rod 13 may be made of a metal material or the like, whereby the friction between the slider 12 and the support rod 13 can be reduced, enabling the slider 12 to slide more smoothly. Further, the base 11 and the slider 12 may be made of a resin material or the like to improve the insulating property.

Fig. 2 is another schematic view of the security door 1 according to the embodiment of the present invention, and fig. 3 is a schematic view of the housing 14 according to the embodiment of the present invention. In at least one embodiment, as shown in fig. 2-3, the security gate 1 may further include a housing 14. The housing 14 may include a second bottom 141 and a second wall portion 142, and the second wall portion 142 extends from the second bottom 141 in the up-down direction, for example, the second wall portion 142 may extend upward. The base 11 may be provided inside the housing 14 surrounded by the second bottom portion 141 and the second wall portion 142, and the second wall portion 142 restricts the support rod 13 in the sliding direction.

In at least one embodiment, the outer peripheral surface of the first wall portion 112 of the base 11 may abut against the inner peripheral surface of the second wall portion 142 of the housing 14, whereby the housing 14 may position the base 11 in a plane perpendicular to the up-down direction. However, the present application is not limited to this, and the base 11 may be limited in another manner.

In at least one embodiment, the second wall portion 142 may abut against one end and the other end of the support rod 13, respectively, thereby being able to limit the support rod 13 in the sliding direction. However, the present invention is not limited to this, and the support rod 13 may be restricted by another method, for example, fixing the support rod 13 to the first through hole 1121 and the second through hole 1122 of the first wall portion 112 of the base 11.

In at least one embodiment, as shown in fig. 3, a fixing portion 144 may be disposed on the second bottom portion 141 of the housing 14, and the housing 14 may be fixed at a predetermined position by the fixing portion 144. For example, the fixing portion 144 may be a through hole, and the housing 14 may be fixed to the mounting position of the receptacle by inserting a member such as a screw into the fixing portion 144. However, the present application is not limited to this, and other types of fixing portions may be provided on the housing 14.

In at least one embodiment, the safety door 1 may further include an elastic member (not shown). The elastic member may be provided on the outer peripheral side of the support rod 13 between the slider 12 and the first wall portion 112. For example, the elastic member may be a spring that is fitted around the outer peripheral side of the support rod 13, and one end of the spring abuts against the side surface 122 of the slider 12, and the other end abuts against the inner peripheral surface 1123 of the first wall portion 112 that faces the side surface 122. However, the present application is not limited thereto, and the elastic member may be in other forms. By providing the elastic member, it is possible to provide the slider 12 with an urging force for returning the slider 12. For example, in a state where the socket is not used, the slider 12 is positioned at a first position where it blocks an insertion hole 114 (shown in fig. 3) described later by an urging force of the elastic member in the sliding direction; in the case of receiving an external force, for example, in the case where a plug applies an external force to the slider 12, the slider 12 slides in the sliding direction against the application force of the elastic member, from the first position to the second position where the insertion hole 114 is exposed; after the plug is pulled out of the socket, the slider 12 is pushed back to the first position by the elastic member.

Fig. 4 is a schematic view of the base 11 of the embodiment of the present invention, fig. 5 is a schematic view of the slider 12 of the embodiment of the present invention, and fig. 6 is another schematic view of the slider 12 of the embodiment of the present invention.

In at least one embodiment, as shown in FIG. 4, the base 11 further includes a recess 113. The groove 113 is provided in the first bottom 111, extending in the sliding direction. As shown in fig. 5 and 6, the slider 12 may also include a nose rail 122. The convex rail 122 is disposed on a side of the main body portion 121 close to the base 11, that is, the convex rail 122 is disposed on a lower side of the main body portion 121, extending in the sliding direction. The groove 113 of the base 11 supports the raised rail 122 of the slider 12. When the slider 12 slides along the support rod 13, the groove 113 of the base 11 supports the convex rail 122 of the slider 12 at the lower side, whereby the slider 12 can be supported by the support rod 13 and the groove 113 in cooperation, and the stability of sliding of the slider 12 can be further improved, and further, when the plug comes into contact with the slider 12 and an external force in the vertical direction is applied to the slider 12, the stress applied to the portion of the slider 12 in contact with the support rod 13 is reduced by the supporting action of the groove 113, whereby the life of the slider 12 can be improved.

In at least one embodiment, as shown in fig. 4, the groove 113 can include a third bottom 1131 and a third wall 1132, wherein an end of the third wall 1132 remote from the third bottom 1131 abuts the rail 122, and a gap exists between the third bottom 1131 and the rail 122. That is, the upper end of the third wall 1132 of the groove 113 supports the rail 122, and the other part of the groove 113 is not in contact with the rail 122, so that the contact area between the groove 113 and the rail 122 can be reduced, and the frictional force between the groove 113 and the rail 122 can be reduced, thereby enabling the slider 12 to slide more smoothly, and further improving the reliability of the sliding of the slider 12. However, the present application is not limited thereto, and the groove 113 may support the rail 122 in other manners.

In at least one embodiment, as shown in fig. 4 to 6, the lower surface of the rail 122 and the upper surface of the groove 113 may be curved surfaces, wherein the radius of curvature of the lower surface of the rail 122 may be greater than the radius of curvature of the upper surface of the groove 113, whereby the contact area of the rail 122 and the groove 113 can be reduced by simply adjusting the radii of curvature of the lower surface of the rail 122 and the upper surface of the groove 113, so that the slider 12 can slide more smoothly. However, the present application is not limited thereto, and the land track 122 and the groove 113 may have other shapes.

In at least one embodiment, the groove 113 may be formed, for example, as shown in fig. 4, the third bottom 1131 may be formed by recessing the first bottom 111 downward, and an end of the third wall portion 1132 distant from the third bottom 1131 may protrude from the first bottom 111. This can reduce the vertical dimension of the safety door 1, which is advantageous for downsizing the safety door 1. However, the present application is not limited thereto, and the groove 113 may be formed in other manners.

In at least one embodiment, as shown in fig. 4, the bottom 11 may be provided with insertion holes 114 for insertion of plugs at both sides of the groove 113. The insertion hole 114 may be vertically overlapped with the circuit connection portion 143 of the housing 14 shown in fig. 3, and after the plug is inserted into the insertion hole 114, the plug may be electrically connected to the socket through the insertion hole 114.

In at least one embodiment, as illustrated in fig. 4, the first through hole 1121 in the side wall 112 may be provided above one end in the sliding direction of the groove 113, and the second through hole 1122 may be provided above the other end in the sliding direction of the groove 113, with the slide lever 13 coinciding with the groove 113 as viewed in the up-down direction. This enables the slider 12 to be reliably supported in a simple manner.

In at least one embodiment, as shown in fig. 5, the main body 121 includes a fourth bottom 1212 and a fourth wall 1213, the fourth wall 1213 extends from the fourth bottom 1212 in the up-down direction, and the channel 1211 includes a third through hole 1211-1, a fourth through hole 1211-3 and a receiving groove 1211-2, wherein the third through hole 1211-1 and the fourth through hole 1211-3 are oppositely disposed on the fourth wall 1213, and the receiving groove 1211-2 is disposed on the fourth bottom 1212 and is located between the third through hole 1211-1 and the fourth through hole 1211-3 in the sliding direction. Thereby, the support rod 13 can penetrate the body portion 121 of the slider 12 through the passage 1211.

In at least one embodiment, as shown in fig. 5, the main body portion 121 is opened above the middle portion of the passage 1211, i.e., the receiving groove 1211-2, whereby, in a case where the support rod 13 penetrates the passage 1211, the upper portion of the outer circumferential surface of the support rod 13 is in contact with the slider 12 only at the third through hole 1211-1 and the fourth through hole 1211-2, whereby the contact area of the support rod 13 with the slider 12 can be further reduced, and thus, the frictional force received by the slider 12 can be further reduced, and the reliability of the sliding of the slider 12 can be further improved. However, the present application is not limited thereto, and the channel 1211 may be provided in other manners.

In at least one embodiment, the heights of the third and fourth through-holes 1211-1 and 1211-3 in the up-down direction may be the same, and the inner diameters of the two may be equal. The bottom surface of the receiving groove 1211-2 may be a curved surface, the radius of curvature of the bottom surface of the receiving groove 1211-2 may be equal to the inner diameters of the third through hole 1211-1 and the fourth through hole 1211-3, and the receiving groove 1211-2 connects the third through hole 1211-1 and the fourth through hole 1211-3. However, the present application is not limited thereto, and the channel 1211 may be provided in other manners.

In at least one embodiment, the inner diameters of the third and fourth through holes 1211-1 and 1211-2 may be sized to be slightly larger than the outer diameter of the support rod 13, that is, the inner diameters of the third and fourth through holes 1211-1 and 1211-2 and the outer diameter of the support rod 13 may be sized in the following manner: when the slider 12 receives an external force in the vertical direction, the lower side of the support rod 13 does not abut against the third through hole 1211-1 and the fourth through hole 1211-2. Therefore, the friction force applied to the slider 12 during the sliding process can be further reduced, and the reliability of the sliding of the slider 12 can be further improved.

In at least one embodiment, a detent mechanism may be provided in the emergency gate 1, for example, as shown in fig. 4, the bottom 11 may include a first detent groove 115 and a second detent groove 116. A first detent groove 115 and a second detent groove 116 are provided in the first bottom 111. As shown in fig. 5 and 6, the slider 12 may include a first wing 123, a second wing 124, a first protrusion 125, and a second protrusion 126. The first wing part 123 and the second wing part 124 are symmetrically disposed at both sides of the body part 121 in the left-right direction perpendicular to both the sliding direction and the up-down direction. The first and second protrusions 125 and 126 are respectively disposed at one sides of the first and second wings 123 and 124 close to the base 11. When the first detent groove 115 engages with the first protrusion 125 or the second detent groove 116 engages with the second protrusion 126, the slider 12 can be prevented from sliding in the sliding direction. This can prevent the slider 12 from moving when a member other than the plug (e.g., a finger of a child) is inserted into the socket, thereby electrically connecting the other member to the socket. When another member (for example, a finger of a child or the like) is erroneously inserted into the socket, an unbalanced force in the left-right direction is usually applied to the slider 12, and the slider 12 rotates about the support rod 13 by the force, so that the first detent groove 115 engages with the first projection 125 or the second detent groove 116 engages with the second projection 126, whereby the slider 12 can be prevented from being moved by the other member. However, the present application is not limited thereto, and the brake mechanism may be provided in another manner.

In at least one embodiment, with the slider 12 in the first position blocking the receptacle 114, the first protrusion 125 coincides with the first detent groove 115 and the second protrusion 126 coincides with the second detent groove 116 as viewed in the up-down direction.

In at least one embodiment, where the fourth bottom portion 1212 of the body portion 121 of the slider 12 is parallel to the first bottom portion 111 of the base 11, the first protrusion 125 is not engaged with the first detent 115 and the second protrusion 126 is not engaged with the second detent 116. Thus, when the slider 12 receives an external force balanced in the left-right direction, that is, when the slider 12 does not rotate about the support rod 13, the first protrusion 125, the second protrusion 126, the first detent groove 115, and the second detent groove 116 do not restrict the movement of the slider 12.

In at least one embodiment, the support bar 13 can support the slider 12 such that the first protrusion 125 does not coincide with the first detent 115 and the second protrusion 126 does not coincide with the second detent 116 as viewed along the sliding direction without the slider 12 rotating about the support bar 13.

In at least one embodiment, as shown in fig. 5, the first wing 123 may include a first inclined portion 1231. In a first direction of the sliding direction, the upper surface of the first inclined part 1231 is gradually inclined downward; the second wing 124 includes a second inclined part 1241, an upper surface of the second inclined part 1241 gradually inclined downward in a first direction of the sliding direction; the inclination angle of the upper surface of the first inclined portion 1231 is the same as the inclination angle of the upper surface of the second inclined portion 1241. By providing the first and second inclined portions 1231 and 1241, an external force in the vertical direction applied to the slider 12 by the plug can be decomposed into a force perpendicular to the first and second inclined portions 1231 and 1241 and a force in the sliding direction, whereby the slider 12 can be smoothly slid in the sliding direction by the external force. The first direction of the sliding direction may be a direction from the second position (the position where the insertion hole is exposed) of the slider 12 to the first position (the position where the insertion hole is blocked).

In at least one embodiment, as shown in fig. 5, the first wing 123 may further include a first step 1232, the first step 1232 being disposed at one side of the first inclined part 1231 in a second direction opposite to the first direction; the second wing 124 may further include a second stepped portion 1242, the second stepped portion 1242 being disposed at one side of the second direction opposite to the first direction of the second inclined portion 1241; the side surface a of the first stepped portion 1232 connected to the first inclined portion 1231 is not perpendicular to the sliding direction, and the side surface B of the second stepped portion 1242 connected to the second inclined portion 1241 is not perpendicular to the sliding direction. By providing the first and second stepped portions 1232, 1242, when the plug comes into contact with the slider 12 and applies a downward external force to the slider 12, the external force can be efficiently converted into a force for sliding the slider 12 in the sliding direction, that is, the slider 12 can be more easily slid in the sliding direction at the initial stage of contact between the plug and the slider 12, and the subsequent sliding operation of the slider 12 can be more smoothly performed by inertia. By setting the side surface a of the first step portion 1232 and the side surface B of the second step portion 1242 to be slightly inclined with respect to the sliding direction, the sliding device can be matched with the arc structure of the plug head portion to ensure that the slider 12 and the plug are always in contact with each other, so that the sliding action of the slider 12 is more continuous and smooth, and the first step portion 1232 and the second step portion 1242 are protected from being damaged. Wherein the second direction of the sliding direction may be a direction from the first position (the position where the insertion hole is blocked) to the second position (the position where the insertion hole is exposed) of the slider 12. However, the present application is not limited to this, and the first step portion 1232 and the second step portion 1242 may be provided in other manners, or the first step portion 1232 and the second step portion 1242 may not be provided.

In at least one embodiment, as shown in fig. 5, a length d1 in the sliding direction of the upper surface of the first step portion 1232 on the side close to the main body portion 121 is smaller than a length d2 in the sliding direction of the upper surface of the first step portion 1232 on the side away from the main body portion 121, a length d3 in the sliding direction of the upper surface of the second step portion 1242 on the side close to the main body portion 121 is smaller than a length d4 in the sliding direction of the upper surface of the second step portion 1242 on the side away from the main body portion 121, and d1 is d3, and d2 is d 4.

In at least one embodiment, as shown in fig. 5, the first wing 123 may further include a third step part 1233, the third step part 1233 being disposed at one side of the first direction of the first inclined part 1231; the second wing 124 may further include a fourth stepped portion 1243, the fourth stepped portion 1243 being disposed at one side of the second inclined portion 1241 in the first direction; the upper surface C of the third stepped portion 1233 connected to the first inclined portion 1231 is not perpendicular to the vertical direction, and the upper surface D of the fourth stepped portion 1243 connected to the second inclined portion 1241 is not perpendicular to the vertical direction. Thus, the thickness of the first and second wing portions 123 and 124 away from the main body portion 121 is greater than the thickness of the first and second wing portions 123 and 124 close to the main body portion 121, and the thickness of the first and second wing portions 123 and 124 is increased to improve the strength of the slider 12 while ensuring that the length of the portions of the first and second inclined portions 1231 and 1241 that contact the plug is sufficient. Further, since the thickness of the portion of the first wing 123 corresponding to the first protrusion 125 is increased and the thickness of the portion of the second wing 124 corresponding to the second protrusion 126 is increased, when the slider 12 receives an unbalanced external force and the first protrusion 125 is engaged with the first detent groove 115 or the second protrusion 126 is engaged with the second detent groove 116, the first wing 123 and the second wing 124 are not easily deformed, and safety in use of the socket can be ensured. However, the present application is not limited to this, and the third step portion 1233 and the fourth step portion 1243 may be provided in other manners, or the third step portion 1233 and the fourth step portion 1243 may not be provided.

In at least one embodiment, as shown in fig. 5, the thickness d5 of the third step portion 1233 in the up-down direction on the side close to the main body portion 121 is smaller than the thickness d6 of the third step portion 1233 in the up-down direction on the side away from the main body portion 121, the thickness d7 of the fourth step portion 1243 in the up-down direction on the side close to the main body portion 121 is smaller than the thickness d8 of the fourth step portion 1243 in the up-down direction on the side away from the main body portion 121, and d5 is d7, and d6 is d 8.

According to the above embodiment, the support rod 13 penetrating the slider 12 is used as a guide mechanism to guide the slider 12 to slide in the sliding direction, so that the friction force between the slider 12 and the guide mechanism can be reduced, and the reliability of the sliding of the slider 12 can be improved; further, since the support rod 13 penetrates the slider 12, the slider 12 can be prevented from deviating from the sliding direction, and the stability of the sliding of the slider 12 can be improved.
