Description

Technical Field

[0001] The present invention relates to a safety door assembly structure of a socket. Background Art

[0002] Sockets are commonly used electrical appliances in daily life, including wall sockets and flexible movable adapter power strips. For safety considerations, such as preventing children from accidentally inserting plugs, and also to prevent foreign objects and moisture from entering, safety doors are currently provided at the housing jacks of sockets. The safety door is also called a protection door. When there is no plug inserted into the socket, the safety door is kept in the closed position under the action of a spring, blocking the housing jack on the socket; when a plug is inserted, the corresponding insert or post on the plug acts on the inclined surface of the safety door, pushing the safety door to the open position, and then enabling electrical connection between the insert or post and the plug-in elastic piece inside the socket.

[0003] Most of the existing safety doors on sockets are directly guided and assembled on the corresponding safety door support seats. The back surface (i.e., the side facing away from the housing jack) of the safety door is in contact with the front surface (i.e., the side facing the housing jack) of the safety door support seat in a surface-to-surface contact form. Since the plug applies force to the safety door through the inclined surface when inserted, this force will be decomposed into a force along the opening direction and a force perpendicular to the opening direction, and the force perpendicular to the opening direction will increase the friction between the back surface of the safety door and the front surface of the safety door support seat, making it difficult to insert the plug. Generally, there are two ways to solve this problem in the prior art: one is to add lubricating oil to the sliding part of the safety door, but this method is prone to cause pollution; the other is to increase the slope of the inclined surface of the safety door. Increasing the slope of the inclined surface of the safety door can alleviate the jamming phenomenon when the plug is inserted, but when the slope is increased to a certain extent, the leakage range of the plug-in elastic piece inside the safety door will increase, resulting in potential safety hazards and a poor safety protection effect.

[0004] Chinese Patent with Publication No. CN2744012Y discloses a socket device, including a panel. There are housing jacks on the panel, and a cover plate is provided on the inner surface of the panel. A safety door is provided between the cover plate and the panel, and the cover plate forms a safety door support seat. A cylindrical surface guide rail protrudes from the front surface of the safety door support seat, and a cylindrical surface groove is provided on the back surface of the safety door. The cylindrical surface groove and the cylindrical surface guide rail are adapted to form a sliding fit, which is beneficial to reducing friction. However, in order to ensure that the safety door slides in a reduced friction surface in cooperation with the safety door support seat, a relatively large gap needs to be left between the back surface of the safety door and the front surface of the safety door support seat. However, with this structure, the safety door assembly structure will not be stable enough and is prone to left-right skew due to factors such as assembly and vibration. When observed from the housing jack, the safety door is in an inclined state, affecting the appearance of the product and the user's impression of the product. Summary of the Invention

[0005] The object of the present invention is to provide a safety door assembly structure for a socket, which solves the problems that the existing safety door has an unstable assembly structure due to reducing friction, affecting the appearance of the product and the impression of the user on the product.

[0006] To achieve the above object, the following technical solutions are adopted in the present invention:

[0007] The safety door assembly structure of the socket includes:

[0008] A safety door, having a front surface and a back surface, and the front surface of the safety door faces the socket housing jack;

[0009] A safety door support seat, with the side facing the safety door being the front surface;

[0010] One of the back surface of the safety door and the front surface of the safety door support seat is provided with a guiding rib, and the other is provided with a guiding chute, and the guiding rib and the guiding chute form a sliding support structure, and the sliding support structure is used to support the safety door and allow the safety door to slide back and forth;

[0011] The safety door can swing left and right relative to the safety door support seat around the sliding support structure;

[0012] The front surface of the safety door support seat and / or the back surface of the safety door is provided with support protrusions;

[0013] The support protrusions are arranged on both sides in the left - right direction of the sliding support structure, and are used to limit the left - right swing amplitude of the safety door.

[0014] Beneficial effects: The guiding rib and the guiding chute cooperate to form a sliding support structure, reducing the sliding contact area, and thus reducing the sliding friction of the safety door, ensuring that the safety door can slide smoothly back and forth; and the front surface of the safety door support seat and / or the back surface of the safety door is provided with support protrusions, and they are arranged on both sides of the sliding support structure, enhancing the structural stability of the safety door, thereby improving the situation of the safety door being skewed left and right, and avoiding affecting the appearance of the product and the impression of the user on the product; at the same time, when in use, even if the safety door tilts left and right under the action of the plug, it can form a small - area support through the support protrusions, without having a great impact on the smooth opening of the safety door, ensuring the smooth movement of the safety door.

[0015] Furthermore, the safety door has a closed position and an open position, and an anti-single-insertion protrusion is provided on the front side of the safety door support seat; the anti-single-insertion protrusion protrudes out of the front side of the safety door support seat, and when the safety door is in the closed position and swings left and right to a set angle under the action of a unilaterally inserted object, the anti-single-insertion protrusion and the safety door form a front and rear stop to prevent the safety door from moving to the open position; the front side of the safety door has a plug force point, and the plug force point corresponds to the shell socket on the socket; the left and right spacing between the support protrusion and the sliding support structure is smaller than the left and right spacing between the corresponding side plug force point and the sliding support structure, so that the safety door can swing with the support protrusion as a fulcrum under the action of a unilaterally inserted object to an angle that forms a front and rear stop with the anti-single-insertion protrusion.

[0016] Beneficial effect: The left-right distance between the support protrusion and the sliding support structure is smaller than the left-right distance between the corresponding side plug force point and the sliding support structure, so that the safety door can swing with the support protrusion as the fulcrum under the action of a unilaterally inserted object to form a front and rear blocking angle with the anti-single-insertion protrusion, preventing the safety door's anti-single-insertion function from failing.

[0017] Furthermore, the width of the guide groove is greater than the width of the guide rib.

[0018] Beneficial effect: The width of the guide slot is greater than the width of the guide rib, which enables the safety door to adapt to different insertion postures of the plug, automatically adjust the supporting position with the safety door support seat, and ensure the flexible movement of the safety door.

[0019] Furthermore, a first supporting protrusion and a second supporting protrusion are provided on both sides of the left and right sides of the sliding support structure, and the second supporting protrusion is located on the side of the first supporting protrusion away from the sliding support structure, that is, the first supporting protrusion and the second supporting protrusion are arranged in a direction gradually away from the sliding support structure, and the second supporting protrusion can allow the safety door to swing in the left and right directions with a greater amplitude than the first supporting protrusion.

[0020] Beneficial effect: The first supporting protrusion and the second supporting protrusion can allow the safety door to swing to different amplitudes in the left and right directions, and can form two-level support for the safety door, so that the safety door can be straightened in grades according to the stress conditions of the safety door, thereby better ensuring the stability of the safety door.

[0021] Furthermore, the back of the safety door is provided with a first inclined plane and a second inclined plane, and the first inclined plane and the second inclined plane are arranged at intervals on the left and right. A raised portion is provided between the first inclined plane and the second inclined plane, and the guide slot is provided on the raised portion. The slot edge of the guide slot protrudes from the corresponding first inclined plane or the second inclined plane, and the first supporting protrusion is formed by the slot edge of the guide slot.

[0022] Beneficial effect: the first supporting protrusion is formed at the edge of the groove opening of the guide slide groove, and there is no need to set the first supporting protrusion separately, so the structure is simple.

[0023] Further, a support recess is provided on the front surface of the safety door support seat, and the guiding convex rib is arranged on the bottom surface of the support recess; the first support protrusion is in blocking cooperation with the side wall of the support recess to limit the swing of the safety door.

[0024] Beneficial effects: The first support protrusion is in blocking cooperation with the side wall of the support recess to limit the swing of the safety door, making the support structure more stable. The space in the safety door installation groove on the installation door support seat is effectively utilized, the interval between the safety door and the safety door support seat is reduced, and the stability of the safety door is further ensured.

[0025] Further, the front surface of the safety door support seat is a plane, and the corresponding support protrusion is arranged on the plane.

[0026] Beneficial effects: The structure is simple, which is convenient for the manufacture of the safety door support seat, and can also conveniently control the support height of the support protrusion, so as to better control the swing amplitude.

[0027] Further, both the left and right sides of the sliding grooves on the front surface of the safety door support seat and the back surface of the safety door are planes, and there is a gap between the front surface of the safety door support seat and the back surface of the safety door. The gap is used to ensure that the safety door can be guided and cooperated through the sliding support structure, and the support protrusion is arranged on the plane.

[0028] Beneficial effects: Adopting the above structure can facilitate the manufacture of the safety door support seat and the safety door, and can also conveniently control the support height of the support protrusion, so as to better control the swing amplitude.

[0029] Further, the second support protrusion is formed at the intersection of the support recess and the front surface of the safety door support seat, and the second support protrusion is used for blocking cooperation with the first inclined surface or the second inclined surface to limit the swing of the safety door.

[0030] Beneficial effects: The second support protrusion is formed at the intersection of the support recess and the front surface of the safety door support seat, and there is no need to separately set the second support protrusion, and the structure is simple.

[0031] The above preferred technical solutions can be adopted separately, and in the case where they can be combined, two or more solutions can be arbitrarily combined. The technical solutions formed by the combination will not be specifically described here and are included in the description of this patent in this form. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The present invention will be further described in detail below in conjunction with embodiments.

[0047] Embodiment 1 of the safety door assembly structure of the socket in the present invention: This safety door assembly structure is used in a socket as shown in Figure 1 The socket includes a wall-embedded housing 18, a safety door gland 14 and a decorative cover 15. A safety door support seat 2 and a safety door are provided in the wall-embedded housing 18. The safety door includes a two-hole safety door 1 and a three-hole safety door 17. As shown in Figure 2As shown, the safety door support seat 2 is provided with a safety door installation groove 13, and the safety door installation groove 13 is provided at two locations, respectively for assembling the two-hole safety door 1 and the three-hole safety door 17, and the safety door can slide back and forth in the corresponding safety door installation groove 13. A spring (not shown in the figure) is provided between the safety door and the safety door support seat 2 for resetting the safety door. The safety door pressure cover 14 is fixed to the embedded wall shell 18 by screws 12, and is sealed to the notch of the safety door installation groove 13, so as to limit the safety door. The decorative cover 15 is buckled on the top of the embedded wall shell 18 and the safety door pressure cover 14, as a decoration of the socket.

[0048] The two-hole safety door 1 and the three-hole safety door 17 in this embodiment have different shapes and the same matching structure as the front side of the safety door support seat 2. In this embodiment, only the assembly structure of the two-hole safety door 1 is described.

[0049] For the convenience of expression, we define Figure 5 The left and right direction is the left and right direction of the assembly structure of the two-hole safety door 1. Figure 5 The up and down direction is the up and down direction of the assembly structure of the two-hole safety door 1, and the two-hole safety door 1 and the safety door support seat 2 are oriented Figure 3 , Figure 4 One side of the housing insertion hole 16 of the middle socket is the front side, and the other side is the back side.

[0050] When the two-hole safety door 1 is in the closed position, the plug-in spring piece in the socket is blocked; when the two-hole safety door 1 is in the open position, the plug-in spring piece in the socket is exposed.

[0051] like Figure 4 As shown, the two-hole safety door 1 has a front side and a back side, and the front side has a plug force point 3, which corresponds to the socket housing jack 16 on the socket and is used to bear the pressure when the plug is inserted. Figure 7 As shown, the back of the two-hole safety door 1 is provided with a first slope 4 and a second slope 5, which are arranged at intervals on the left and right and gradually tilt upward from a direction away from the middle of the left and right directions of the back of the two-hole safety door 1, so as to provide space for the two-hole safety door 1 to swing left and right.

[0052] A raised portion is provided between the first inclined surface 4 and the second inclined surface 5 , and a guide slot 7 is provided on the raised portion. The notch edges on both sides of the guide slot 7 protrude from the corresponding first inclined surface 4 and the second inclined surface 5 respectively, and the notch edges of the guide slot 7 form a first supporting protrusion 6 .

[0053] like Figure 5As shown, a depression is provided in the middle of the front surface of the safety door support base 2 in the left-right direction, and the depression forms a support recess 8. The support recess 8 has a bottom surface and side walls. A guiding convex rib 9 is provided on the bottom surface of the support recess 8. The upper part of the guiding convex rib 9 is semicircular and is used for line contact fit with the guiding sliding groove 7. The guiding convex rib 9 and the guiding sliding groove 7 cooperate to form a sliding support structure. The sliding support structure is used to support the two-hole safety door 1 and allow the two-hole safety door 1 to slide on the sliding support structure. The two-hole safety door 1 can swing left and right relative to the safety door support base 2 around the sliding support structure.

[0054] The left and right side surfaces of the guiding convex rib 9 are perpendicular to the front surface of the safety door support base 2, and the width of the guiding sliding groove 7 is greater than the width of the guiding convex rib 9. As Figure 6 shown, when the two-hole safety door 1 is in the middle position of swinging left and right, there is a gap between the first support protrusion 6 and the side wall of the support recess 8. At the same time, the first support protrusion 6 can form a blocking fit with the two-hole safety door 1 during the left and right swinging process of the two-hole safety door 1 to limit the swinging amplitude of the two-hole safety door 1.

[0055] As Figure 6 shown, a second support protrusion 10 is formed at the intersection of the side wall of the support recess 8 and the front surface of the safety door support base 2. When the two-hole safety door 1 is in the middle position of swinging left and right, there is a gap between the second support protrusion 10 and the first inclined surface 4 or the second inclined surface 5. And during the swinging process of the two-hole safety door 1, the second support protrusion 10 can contact the first inclined surface 4 or the second inclined surface 5 to form a blocking fit to limit the swinging of the two-hole safety door 1.

[0056] First support protrusions 6 and second support protrusions 10 are provided on both the left and right sides of the sliding support structure for limiting the swinging amplitude of the two-hole safety door 1 in the left-right direction. The first support protrusions 6 and the second support protrusions 10 are arranged along the direction gradually away from the sliding support structure, that is, the second support protrusion 10 is located on the side of the first support protrusion 6 away from the sliding support structure. The amplitude of the left-right swinging of the two-hole safety door 1 that the second support protrusion 10 can provide is greater than the amplitude of the left-right swinging of the two-hole safety door 1 that the first support protrusion 6 can provide.

[0057] As Figure 2 shown, an anti-single-insert protrusion 11 is further provided on the front surface of the safety door support base 2. The anti-single-insert protrusion 11 protrudes from the front surface of the safety door support base 2. When the two-hole safety door 1 is in the closed position and swings left and right under the action of inserting an object on one side, when the end of the first inclined surface 4 or the second inclined surface 5 away from the middle is lower than the upper end surface of the anti-single-insert protrusion 11, the anti-single-insert protrusion 11 forms a front-back block with the two-hole safety door 1 to block the two-hole safety door 1 from moving to the open position.

[0058] The left and right distances between the second support protrusion 10 and the sliding support structure are smaller than the left and right distances between the corresponding side plug force points 3 and the sliding support structure, so that the two-hole safety door 1 can swing with the second support protrusion 10 as the fulcrum to an angle where it forms a front and rear stop with the anti-single-insertion protrusion 11 under the action of inserting an object on one side.

[0059] During assembly, the two-hole safety door 1 is installed on the safety door support seat 2. The guiding chute 7 of the two-hole safety door 1 cooperates with the guiding rib 9 on the safety door support seat 2. The first support protrusion 6 and the second support protrusion 10 can limit the left and right swing amplitude of the two-hole safety door 1, making the assembly structure of the two-hole safety door 1 stable and having good aesthetics. At the same time, it also ensures the normal sliding of the two-hole safety door 1. When an object is inserted into the housing jack 16 on one side, the first inclined surface 4 or the second inclined surface 5 on both sides of the two-hole safety door 1 can form a stop fit with the anti-single-insertion protrusion 11, ensuring the safety protection effect of the two-hole safety door 1.

[0060] In Embodiment 2 of the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the two support protrusions are respectively arranged in the middle in the left and right directions of the safety door and the safety door support seat, while in this embodiment, the two support protrusions are both arranged in the middle in the left and right directions of the safety door. In other embodiments, the two support protrusions can also be both arranged in the middle in the left and right directions of the safety door support seat.

[0061] In Embodiment 3 of the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, in order to have the anti-single-insertion function, the two support protrusions are respectively arranged in the middle in the left and right directions of the safety door and the safety door support seat, while in this embodiment, the safety door does not have the anti-single-insertion function, and the two support protrusions are arranged on both sides in the left and right directions of the safety door. In other embodiments, the two support protrusions can also be arranged on both sides in the left and right directions of the safety door support seat.

[0062] In Embodiment 4 of the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, two support protrusions are provided on each of the left and right sides of the sliding support structure, while in this embodiment, only one support protrusion is provided on each of the left and right sides in the left and right directions of the sliding support structure.

[0063] In Embodiment 5 of the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the width of the guiding chute is greater than the width of the guiding rib, while in this embodiment, the width of the guiding chute matches the width of the guiding rib.

[0064] In Embodiment 6 of the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, a support recess is provided on the front surface of the safety door support seat, while in this embodiment, the front surface of the safety door support seat is a flat surface, and the corresponding support protrusion is provided on the flat surface.

[0065] Embodiment 7 in the present invention is different from Embodiment 1 in that in Embodiment 1, there are two inclined surfaces on the back of the safety door, and there is a supporting recess on the front of the safety door support seat. In this embodiment, both the left and right sides of the slideway on the front of the safety door support seat and the back of the safety door are flat surfaces, and there is a gap between the front of the safety door support seat and the back of the safety door. The gap is used to ensure that the safety door can be guided and fitted through the sliding support structure. At this time, the support protrusion is provided on the corresponding flat surface.

[0066] The above is only a preferred embodiment of the present application and is not intended to limit the present application. The scope of patent protection of the present application is subject to the claims. Any equivalent structural changes made by using the description and drawings of the present application should, by the same token, be included in the protection scope of the present application.
