[0001] The utility model relates to the field of socket components, in particular to a protective door structure, a socket and a socket strip. Background Art

[0002] Power strips are essential electrical devices in our daily lives. The safety of the sockets within these strips is a major concern. To improve socket safety, socket protection doors are installed at the socket outlets. These doors come in two- and three-prong configurations, each removably mounted within a door base and covering the socket outlets.

[0003] The existing socket protection door uses a left and right slider structure for blocking (refer to the prior art with application number 201711064284.0), but if this method is affected by external force, it is easy to cause the spring to deflect and affect the movement of the slider, thereby making it impossible for the socket protection door to slide open smoothly, affecting the normal use of the socket. Utility Model Content

[0004] The utility model provides a protective door structure, a socket and a socket strip, which mainly solves the problem that the existing socket protective door uses a slider structure for shielding, but if this method is offset by external force, it is easy to cause the spring to deviate and affect the movement of the slider, thereby making the structural stability of the socket protective door poor.

[0005] The utility model provides a protection door structure. The protection door is a frame-shaped structure. An outer edge of one side of the protection door is formed with a first inclined surface in an outward descending posture.

[0006] Preferably, a second inclined surface with an inward descending posture is formed on an inner edge of one side of the protection door, and the first inclined surface is arranged in parallel with the second inclined surface.

[0007] Preferably, the first inclined surface and the second inclined surface have the same slope.

[0008] Preferably, the inner protrusion of the protection door forms a limiting column, and the limiting column is respectively arranged on both sides of the same edge of the protection door on the first inclined surface.

[0009] Preferably, the symmetrical edges on the protection door are concave to form a locking position, and the two locking positions are respectively arranged adjacent to the edge where the first inclined surface is located.

[0010] The utility model further provides a socket, comprising the aforementioned protective door structure, and further comprising:

[0011] The bottom shell is formed with at least a first wiring hole and a second wiring hole symmetrically arranged along the central axis of the bottom shell; a limit plate is formed on the edge of the first wiring hole near the second wiring hole; the protective door is stacked above the bottom shell and sleeved outside the limit plate;

[0012] A panel is formed with at least a first through hole and a second through hole matched with the first wiring hole and the second wiring hole; the panel is stacked above the protective door and is detachably mounted on the bottom shell;

[0013] An elastic member, both ends of which are respectively disposed to abut against the limiting pillar of the protective door and the limiting plate of the bottom shell;

[0014] In the initial state, the first and second inclined surfaces of the protective door completely cover the first and second wiring holes; in the plugged state, the first and second inclined surfaces of the protective door translate and are staggered with the first and second wiring holes.

[0015] Preferably, the bottom shell includes:

[0016] A limit frame, a protrusion formed on the end surface of the bottom shell facing the protective door; the limit frame arranged around the first wiring hole and the second wiring hole has a height equal to the height of the protective door and a length greater than the length of the protective door;

[0017] In the initial state, the outer side of the first inclined surface abuts against the inner side of the limit frame; in the plugged state, the outer side of the edge of the second inclined surface abuts against the inner side of the limit frame.

[0018] Preferably, the bottom shell is further formed with a third wiring hole, and the third wiring hole, the first wiring hole and the second wiring hole are distributed in a herringbone shape;

[0019] The panel is formed with a third through hole matched with the third wiring hole;

[0020] The limiting frame is arranged around the outer edges of the first wiring hole, the second wiring hole and the third wiring hole.

[0022] The utility model also provides a socket strip, comprising the aforementioned socket;

[0023] The socket strip is provided with a plurality of sockets arranged in parallel.

[0024] As can be seen from the above, the application of the technical solution provided by the utility model can achieve the following beneficial effects:

[0025] First, the protective door structure proposed in this utility model is a frame-shaped structure, which can improve its own structural stability. At the same time, it ensures the stability of the translation process during the pin insertion process, which can effectively ensure that the socket and strip remain normal and stable after repeated opening and closing of the protective door, thereby ensuring the service life of the socket and strip;

[0026] Second, the protective door structure proposed by the present invention is provided with a first inclined surface and a second inclined surface that are parallel to each other, which can cover the two corresponding sockets. When the pin enters, the simultaneous force of the two sides makes the sliding of the protective door smoother, ensuring the normal use of the socket while maintaining the safety of the protective door.

[0027] Third, the first and second slopes of the protective door proposed by the present invention have the same slope, which means that when the pin enters, the same force is exerted on the two slopes, further ensuring the horizontal movement of the protective door and achieving the repeated protection effect of the protective door on the socket;

[0028] Fourth, the protective door structure proposed by the present invention is provided with a limiting column for sleeve-mounting the elastic member, which can ensure the association between the elastic member and the protective door, effectively ensuring that the elastic member pushes the protective door to restore the protective door to its original state after the pin is removed;

[0029] Fifth, the latch provided on the protective door structure of the present invention can effectively limit the location of the elastic member, preventing the elastic member from shifting due to its own elastic force during compression and release, thereby ensuring the connection between the elastic member and the protective door.

[0030] Sixth, the socket proposed by the present invention limits the movement range of the protective door structure through the limit frame, and can only achieve horizontal movement, further ensuring the protective effect of the protective door on the socket. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without expending creative work are within the scope of protection of the present invention.

[0036] The existing socket protection door uses a slider structure for shielding. However, if this method is offset by external force, it is easy to cause the spring to deflect and affect the movement of the slider, thereby causing the structural stability of the socket protection door to be poor.

[0037] Example 1

[0038] like Figure 1 As shown, in order to solve the above problems, this embodiment proposes a protection door structure. The protection door 100 is a frame-shaped structure, and a first inclined surface 110 with a downward posture is formed on the outer edge of one side of the protection door 100.

[0039] Preferably, in this embodiment, the first inclined surface 110 is provided on one short side of the protection door 100 structure, and the length of the first inclined surface 110 is equal to the length of the short side.

[0040] Preferably, in this embodiment, the starting end of the first slope 110 is located at the front end surface of the protection door 100 , and the current edge of the protection door 100 provided with the first slope 110 is also provided with a horizontal surface of the front end surface, and is seamlessly connected with the first slope 110 .

[0041] In this embodiment, the first inclined surface 110 is used to enable the protection door 100 to move horizontally and in the opposite direction of the inclined surface 110 when the protection door 100 is acted upon by the pin from top to bottom.

[0042] More specifically, a second inclined surface 120 with an inwardly descending posture is formed on an inner edge of one side of the protection door 100 , and the first inclined surface 110 and the second inclined surface 120 are arranged in parallel.

[0043] Preferably, in this embodiment, the first inclined surface 110 and the second inclined surface 120 have the same width and the same slope, but the length of the first inclined surface 110 is greater than the length of the second inclined surface 120 .

[0044] Preferably, the protection door 100 in this embodiment is a two-plug protection door 100, and the first inclined surface 110 and the second inclined surface 120 are arranged corresponding to the two plug holes on the socket.

[0045] In this embodiment, the first inclined surface 110 and the second inclined surface 120 are arranged so that when pins are inserted into the two sockets respectively, the protective door 100 can be simultaneously moved downward along the inclined surface in the opposite direction of the inclined surface, making the movement of the protective door 100 smoother.

[0046] More specifically, the inner protrusion of the protection door 100 forms a limiting post 130 , and the limiting post 130 and the first inclined surface 110 are respectively disposed on both sides of the same edge of the protection door 100 .

[0047] Preferably, in this embodiment, the limiting post 130 is disposed at the center of the inner side of the current edge.

[0048] Preferably, the limiting column 130 in this embodiment is a square columnar structure.

[0049] In this embodiment, since the first inclined surface 110 enables the protection door 100 to move along the inclined surface direction, the limiting column 130 is moved toward the direction where the second inclined surface 120 is provided.

[0050] More specifically, the protective door 100 has symmetrical edges that are concavely formed with latching positions 140 , and the two latching positions 140 are respectively disposed adjacent to the edges where the first inclined surface 110 is located.

[0051] Preferably, in this embodiment, the latching positions 140 are all square groove structures.

[0052] Preferably, in this embodiment, the two latching positions 140 have the same depth and width.

[0053] In this embodiment, the provision of the latching position 140 can effectively limit the elastic member in the vertical direction when the elastic member is subsequently installed.

[0054] In this embodiment, the front and rear faces of the protective door 100 are both composed of two planes connected at an obtuse angle, and a hook is provided corresponding to the rear face arranged opposite to the first inclined surface 110, which can be used to clamp on the edge of the wiring hole to fix the movement range of the protective door 100 on the socket 200.

[0055] Example 2

[0056] like Figure 1 and Figure 2As shown, in order to solve the above-mentioned problems, this embodiment proposes a socket 200, including the protective door 100 structure of Example 1, and also including a bottom shell 210, a panel and an elastic member 220; at least a first wiring hole and a second wiring hole symmetrically arranged along the central axis of the bottom shell 210 are formed on the bottom shell 210; a limiting plate 230 is formed on the edge protrusion of the first wiring hole near the second wiring hole; the protective door 100 is stacked on the bottom shell 210 and is sleeved on the outside of the limiting plate 230; at least a first through hole and a second through hole matching the first wiring hole and the second wiring hole are formed on the panel; the panel is stacked on the protective door 100, and the panel and the bottom shell 210 are detachable and installed; the end portions of the elastic member 220 are respectively abutted against the limiting column 130 of the protective door 100 and the limiting plate 230 of the bottom shell 210.

[0057] Preferably, the elastic member 220 in this embodiment is a spring, and in the initial state, the distance between the limiting column 130 of the protective door 100 and the limiting plate 230 of the bottom shell 210 is less than the static length of the spring, that is, the protective door 100 has a movement tendency to restore to the initial state.

[0058] Preferably, the distance between the two latches 140 on the protective door 100 in this embodiment is less than the length of the limiting plate 230 and greater than or equal to the width of the elastic member 220. In this embodiment, the latches 140 effectively limit the elastic member 220 to generate only horizontal elastic force in both the compressed and released states, achieving horizontal compression and extension, thereby preventing displacement of the elastic member 220 from affecting the automatic restoration of the protective door 100.

[0059] Preferably, in this embodiment, the inner height of the end portion of the protective door 100 provided with the second inclined surface 120 is equal to the length of the limiting plate 230 , so that the setting position of the protective door 100 remains fixed.

[0060] In this embodiment, in the initial state, the first bevel 110 and the second bevel 120 of the protective door 100 completely cover the first wiring hole and the second wiring hole; in the plugged state, the protective door 100 moves horizontally until the first bevel 110 and the second bevel 120 are respectively offset with the first wiring hole and the second wiring hole, and the pins are successfully aligned and connected with the first wiring hole and the second wiring hole.

[0061] More specifically, it also includes a limit frame 240 protruding from the end surface of the bottom shell 210 facing the protective door 100; the limit frame 240 arranged around the first wiring hole and the second wiring hole has a height equal to the height of the protective door 100 and a length greater than the length of the protective door 100.

[0062] Preferably, in this embodiment, the height of the limiting frame 240 is equal to the depth of the protective door 100 .

[0063] In this embodiment, in the initial state, the outer side of the first inclined surface 110 abuts the left inner side of the limit frame 240, and the free edge of the second inclined surface 120 abuts the back side of the limit plate 230; in the plugged state, the outer edge of the second inclined surface 120 abuts the inner right side of the limit frame 240.

[0064] More specifically, the bottom shell 210 is also formed with a third wiring hole, and the third wiring hole is distributed in a herringbone shape with the first wiring hole and the second wiring hole; a third through hole is formed on the panel to match the third wiring hole; and the limiting frame 240 is arranged around the outer edges of the first wiring hole, the second wiring hole and the third wiring hole.

[0065] Preferably, in this embodiment, the limit frame 240 is arranged around the outer edge of the bottom shell 210, wherein a closed loop structure is extended outside the third wiring hole to frame the third wiring hole, and a partition is extended outside the first wiring hole and the second wiring hole to separate the third wiring hole from the first wiring hole and the second wiring hole, and the partition is used to place the protective door 100.

[0066] Preferably, the edge corners of the limiting frame 240 can also be connected to external fasteners for mounting the bottom case 210 and the panel.

[0067] In this embodiment, since the third wiring hole corresponds to the ground wire, the two-plug protection door 100 described in Example 1 only protects the neutral wire and live wire corresponding to the first wiring hole and the second wiring hole. A separate protection door 100 can also be provided for the third wiring hole.

[0068] Example 3

[0069] like Figure 3 As shown, in order to solve the aforementioned problem, this embodiment proposes a socket strip 300 including the socket 200 described in Example 2.

[0070] The power strip 300 of this embodiment includes a single row of multiple sockets 200 arranged in parallel, or includes a double row / triple row / N rows of multiple sockets 200 arranged in rows and columns.

[0071] In summary, the protective door structure, socket and extension strip described in Examples 1 to 3 improve the structural stability of the protective door on the socket by setting a frame-shaped protective door structure. At the same time, through the first inclined surface and the second inclined surface set in parallel on the protective door, two forces in the same direction and synchronously are applied to the protective door when the pin enters, making the movement of the protective door smoother, thereby improving the structural stability and service life of the socket equipped with the protective door.

[0072] The above-described embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments shall be included in the scope of protection of this technical solution.
