Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a through-type wiring dark box. Background Art

[0002] The junction box is an essential electrician auxiliary tool in construction projects or various types of decoration construction. There are certain differences between the junction box and the junction box. The junction box is mainly used for the installation of various switches, sockets and other electrical wiring panels; while the junction box generally needs to be pre-buried and installed. It can also connect wires, transition various electrical circuits, and protect the safety of the circuits. The junction boxes can also be used in series as in the Chinese utility model patent with the authorization announcement number CN210898414U.

[0003] The wire threading holes on the two sides of the existing wiring box are generally single-hole to single-hole, and a group of wires are connected from the hole on one side and then connected from the hole on the opposite side. Although this single-hole to single-hole structure can effectively ensure the accuracy of wire connection and connection, it cannot meet the needs of connecting and disconnecting multiple groups of wires from the same direction at the same time; and when the direction of the wires changes greatly when they are connected or disconnected, more interference occurs between the single-hole to single-hole wiring box and the wires, which can easily damage the wires.

[0004] There are also junction boxes that connect multiple single holes on the side to form long strip holes. This type of junction box is prone to line confusion when connecting wires.

[0005] At the same time, the screws that serve as fixation inside the common junction box may also damage the wires in the box. The threaded holes in the junction box used to cooperate with the screws are also easily entered by mud and sand during use, resulting in a failure to cooperate with the screws, thereby causing the panel to be unable to be fixed on the junction box. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a through-type wiring box for solving the problem that when multiple wiring boxes are connected in series in the prior art and multiple groups of wires are connected to the switch panel from the same position, the lines are easily confused.

[0007] To achieve the above-mentioned purpose and other related purposes, the utility model provides a through-type wiring dark box, including a box body with an open top and a closed bottom, the box body including a first side surface and a second side surface arranged opposite to each other, the first side surface and the second side surface are provided with a plug-in component, a socket component and a threading hole, the periphery of the threading hole is connected with a threading plate that can be knocked down, the first side surface and the second side surface are respectively provided with a plurality of through-plates that can be knocked down, the threading holes are arranged on the through-plates, and two different through-plates on the same side surface are not connected; panel mounting ears are installed on the first side surface and the second side surface, and main threaded holes are arranged on the panel mounting ears; a wire blocking column is arranged at the bottom of the box body, and the wire blocking column is located between two different through-plates on the same side surface; a nail receiving groove is opened in the wire blocking column, and a screw screwed into the main threaded hole enters the nail receiving groove, and the wires in the box body cannot enter the gap between the lower surface of the panel mounting ear and the upper surface of the wire blocking column.

[0008] Optionally, an anti-blocking plate for closing the main threaded hole is provided above the panel mounting ear.

[0009] Optionally, the wire blocking column is provided with a secondary threaded hole coaxial with the main threaded hole.

[0010] Optionally, a sliding groove is provided in the panel mounting ear, a nut is slidably installed in the sliding groove, and the main threaded hole is opened on the nut.

[0011] Optionally, the box body further includes a third side surface and a fourth side surface, and both the third side surface and the fourth side surface are provided with a knockable long strip plate, and one of the long strip plates is provided with a plurality of the threading holes.

[0012] Optionally, outwardly protruding locking rings are provided at the threading holes on the third side and the fourth side, and wavy patterns are provided on the outer circumferential surfaces of the locking rings.

[0013] Optionally, a knockable square plate is provided at the bottom of the box body, and the threading hole is provided on the square plate.

[0014] Optionally, the plug assembly includes an X-direction buckle, and the socket assembly includes an X-direction slot, and the X-direction buckle is inserted into the X-direction slot.

[0015] Optionally, the plug assembly further includes a Y-direction buckle, and the socket assembly further includes a Y-direction slot, and the X-direction buckle is inserted into the X-direction slot while the Y-direction buckle is inserted into the Y-direction slot.

[0016] As described above, the through-type wiring dark box of the utility model has at least the following beneficial effects:

[0017] 1. The through-type junction box is provided with knockable through plates on the first side and the second side of the box body for series connection. A through plate is provided with a threading hole. The two different through plates on the same side are not connected. When only a single group of wires needs to be connected to the access box body, the user only needs to knock down the threading plate; and when multiple groups of wires need to be connected to the access box body from the same direction at the same time, the user knocks down the through plate at this direction, and the multiple groups of wires pass through the through holes of the knocked-down through plate; thereby solving the problem in the prior art that multiple junction boxes are buckled together in series, and the lines are easily confused when multiple groups of wires are connected to and taken out of the switch panel from the same direction.

[0018] 2. The wires in the through-type junction box cannot enter the gap between the lower surface of the panel mounting ear and the upper surface of the wire blocking post. That is, the gap between the lower surface of the panel mounting ear and the upper surface of the wire blocking post is designed to be smaller than the diameter of the wire, thereby avoiding the surface of the wire being damaged by the screws. At the same time, the wire blocking post is located between two different through-plates on the same side, and the wire blocking post is against the first side and the second side of the junction box, thereby enhancing the firmness of the junction box.

[0019] 3. This through-type junction box is designed with a blocking piece for closing the main threaded hole above the panel mounting ear. When installing the junction box, the blocking piece is closed to prevent the main threaded hole used for cooperating with the screws in the junction box from entering mud and sand during use, resulting in the inability to cooperate with the screws, thereby causing the panel to be unable to be fixed on the junction box; after the junction box is installed, the blocking piece is opened to ensure that the main threaded hole can smoothly cooperate with the screws to fix the panel on the box body.

[0020] 4. The through-type junction box is provided with a sliding groove in the panel mounting ear, a nut is installed in the sliding groove, and the main threaded hole is opened on the nut. Even if the position of the main threaded hole deviates, the panel can be smoothly installed in a horizontal position.

[0021] 5. The through-type junction box is designed with a secondary threaded hole coaxial with the main threaded hole on the wire blocking column. When defects such as gaps appear in the embryo teeth of the main threaded hole, the panel can still be installed on the box body by screwing the screw into the secondary threaded hole.

[0030] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0031] See also Figures 1 to 6 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0032] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0033] See also Figures 1 to 3The utility model provides a through-type wiring dark box, including a hollow box body 1 with an open top and a closed bottom, wherein the four sides of the box body 1 are a first side, a second side, a third side and a fourth side, wherein the first side and the second side are opposite to each other and are both provided with a panel mounting ear 2, and a main threaded hole 31 is provided on the panel mounting ear 2, and the panel is generally fixed to the box body 1 by screws and the main threaded hole 31; the bottom and sides of the box body 1 are provided with threading holes, and the inner walls of the threading holes are connected with a threading plate 12 that can be knocked off, and the threading plate 12 is knocked off when the wires need to be connected; the first side and the second side of the box body 1 used for being connected in series with other box bodies 1 are respectively provided with a plug assembly 4 and a socket assembly 5, and the structures of the plug assembly 4 and the socket assembly 5 have various forms, which will be explained in detail later.

[0034] like Figure 1 As shown, the box body 1 is provided with a plurality of knockable through plates 13 on the first side and the second side for series connection, a through plate on the first side corresponds to a through plate on the second side, each through plate 13 is provided with a threading hole, and two different through plates 13 on the same side are not connected. When only a single group of wires are to be connected to or out of the box body 1, the user only needs to knock down the threading plate 12; and when multiple groups of wires are to be connected to or out of the box body 1 from the same direction at the same time, the user knocks down the through plate 13 at this direction, and multiple groups of wires pass through the through holes of the knocked-down through plates 13; thereby solving the problem in the prior art that multiple wiring boxes are buckled together in series and multiple groups of wires are easily confused when they are connected to or out of the switch panel from the same direction, and is convenient for users to use.

[0035] The size of the through plate 13, the size of the threading hole and the number of the threading holes are designed according to needs. One of the through plates 13 is provided with a threading hole, which can better ensure that the directions of the wires connected to the access box body 1 are consistent, avoiding the occurrence of wires being connected and connected from two threading holes with different directions.

[0036] like Figure 2 As shown, a wire blocking post 6 is provided at the bottom of the box body 1, and the wire blocking post 6 is located between two different through plates 13 on the same side. The wire blocking post 6 abuts against the first side and the second side of the wiring dark box, thereby enhancing the firmness of the wiring dark box; a nail receiving groove 61 is provided in the wire blocking post 6, and the screw screwed into the main threaded hole 31 enters the nail receiving groove 61. Because the wire blocking post 6 is longer than that in the existing box body 1, the wires in the box body 1 cannot enter the gap between the lower surface of the panel mounting ear 2 and the upper surface of the wire blocking post 6, that is, the gap between the lower surface of the panel mounting ear 2 and the upper surface of the wire blocking post 6 is smaller than the diameter of the wire, thereby preventing the surface layer of the wire from being damaged by the screw.

[0037] like Figure 2 and Figure 3As shown, a blocking piece 7 for closing the main threaded hole 31 is provided above the panel mounting ear 2. When installing the present wiring dark box, the blocking piece 7 is closed to prevent the main threaded hole 31 in the wiring dark box used for cooperating with the screw from entering mud and sand during use, resulting in failure to cooperate with the screw, thereby causing the panel to be unable to be fixed on the wiring dark box; after the present wiring dark box is installed, the blocking piece 7 is opened to ensure that the main threaded hole 31 can smoothly cooperate with the screw to fix the panel on the box body 1; the blocking piece 7 can be rotatably connected to the inner wall of the box body 1, and can also be rotatably connected to the panel mounting ear 2, as long as it can ensure that when the present through-type wiring dark box is pre-buried, mud and sand are blocked from entering the main threaded hole 31. The designer can choose the detailed connection method and position relationship according to the actual situation, which will not be repeated here.

[0038] In another embodiment, see Figure 3 A sliding groove is provided in the panel mounting ear 2, and a nut 3 is slidably installed in the sliding groove. The main threaded hole 31 is opened on the nut 3. When the position of the main threaded hole 31 deviates, the user can also smoothly install the panel to a horizontal position, thereby enhancing the applicability of the through-type wiring box.

[0039] In another embodiment, see Figure 3 The wire blocking column 6 is provided with a secondary threaded hole coaxial with the main threaded hole 31. When there is a defect such as a gap in the embryo of the main threaded hole 31, the panel can still be installed on the box body 1 by screwing the screw into the secondary threaded hole.

[0040] In another embodiment, see Figure 1 The side of the box body 1 adopts a double-layer keel 11, which can be set on the first side and the second side for series connection, or on all sides of the box body 1, and the thickness of the keel 11 can be strengthened according to the needs of use; whether it is the design of the double-layer keel 11 or the design of strengthening the thickness of the keel 11, it is to make the structure of the through-type wiring box more stable, not easy to deform, and durable.

[0041] In another embodiment, see Figure 1 The outer surface of the box body 1 is provided with concave-convex horizontal lines, thereby increasing the adhesion between the outer surface of the box body 1 and the pre-embedded cement, making the installation of the through-type wiring dark box more secure.

[0042] In another embodiment, see Figure 1A knock-off long strip 14 is provided on the third and fourth sides of the box body 1, and all the threading holes on the third and fourth sides are opened on the long strip 14; when multiple groups of wires need to be connected and taken out on the non-series side of the box body 1, the entire long strip 14 is knocked off. At the same time, because this side is not connected in series with other wiring boxes, there is no need to consider the confusion of the directions of multiple groups of wires after being connected and taken out, and there is no problem of confusion of the directions of multiple groups of wires after being connected to the wiring box.

[0043] like Figure 4 As shown, the threading holes at the bottom of the box body 1 are provided on a knockable square plate 15. When multiple sets of wires need to be connected and taken out from the bottom of the box body 1, the entire square plate 15 is knocked down. At the same time, because the bottom surface is not connected in series with other junction boxes, there is no need to consider the confusion of directions of multiple sets of wires after being connected and taken out, and there is no problem of confusion of directions of multiple sets of wires after being connected to the junction boxes. At the same time, because the square hole formed after the square plate 15 is knocked down is larger than the threading hole, the wires connected from the bottom of the box body 1 will not be overheated due to being too tight and cause short circuit.

[0044] In another embodiment, see Figure 4 and Figure 5 We take the direction perpendicular to the first side surface as the X direction, and use it to determine the Y direction and the Z direction; the plug assembly 4 includes an X-direction buckle 41, and the socket assembly 5 includes an X-direction slot 51. The X-direction buckle 41 is inserted into the X-direction slot 51 to achieve the series connection of different box bodies 1. The series connection in one direction is obviously not firm, so a more firm series connection method will be introduced in the afternoon.

[0045] In another embodiment, see Figure 4 and Figure 5 The plug-in assembly 4 also includes a Y-direction buckle 42, and the socket assembly 5 also includes a Y-direction slot 52. When the X-direction buckle 41 is inserted into the X-direction slot 51, the Y-direction buckle 42 is inserted into the Y-direction slot 52. The two through-type wiring boxes connected in series are fixed from both the "X" and "Y" directions, which is obviously more secure than fixing them from only the "X" direction.

[0046] In another embodiment, in addition to fixing the two box bodies 1 connected in series from the "X" and "Y" directions, they can also be fixed from the "X" and "Z" directions; that is, the plug-in component 4 also includes a Z-direction buckle, and the socket component 5 also includes a Z-direction slot. When the X-direction buckle 41 is inserted into the X-direction slot 51, the Z-direction buckle is inserted into the Z-direction slot.

[0047] In another embodiment, see Figure 4 and Figure 5We introduce a more specific method of fixing the series connection from the "X" and "Y" directions. The plug component 4 includes a first annular flange located below the panel mounting ear 2, and three sides of the first annular flange away from the panel mounting ear 2 are provided with sockets; the socket component 5 includes a second annular flange located below the panel mounting ear 2, and three sides of the second annular flange away from the panel mounting ear 2 are provided with convex buckles corresponding to the sockets, and a slot is provided above one side of the second annular flange close to the panel mounting ear 2; that is, the first annular flange is an X-direction buckle 41, the slot provided on the second annular flange is an X-direction slot 51, the convex buckle is a Y-direction buckle 42, and the socket is a Y-direction slot 52.

[0048] The specific method of fixing the series connection in the "X" and "Z" directions will not be described in detail.

[0049] In another embodiment, see Figure 1 The terminal board is provided with concave and convex patterns, which makes it easier for users to knock off the terminal board. And because it is easy to knock off, burrs are not easy to form on the inner wall of the wiring hole, thus avoiding burrs damaging the wires.

[0050] In another embodiment, please refer to the figure, the bottom edge of the box body 1 adopts a rounded corner design, which is more convenient for users to install.

[0051] In another embodiment, see Figure 4 A cover plate 8 is installed on the opening on the upper part of the box body 1, and the cover plate 8 and the opening are connected by a snap buckle. A spirit level 9 is installed on the cover plate 8. The design of the cover plate 8 can effectively prevent mud and putty from entering the interior of the box body 1 when using the through-type wiring box, and the design of the spirit level 9 allows the user to install the through-type wiring box more quickly and with more accurate positioning; at the same time, in order to make the user agree to open the cover plate 8, a notch is opened at the edge of the cover plate 8.

[0052] In another embodiment, see Figure 6 , outwardly protruding locking rings 16 are provided at the threading holes on the third and fourth sides of the box body 1, and the wire conduit is connected to the box body 1 through the locking rings 16, while the wiring box without the locking rings 16 needs to use a cup comb or other devices to connect with the wires; at the same time, in order to make the connection between the wire conduit and the box body 1 more firmly, the outer peripheral surface of the locking ring 16 is provided with wavy patterns, or other suitable patterns are provided.

[0053] In other embodiments, as shown in the figure, for commercial purposes, some advertisements, display texts, etc. can also be sprayed or pasted on the cover plate 8.

[0054] In summary, the utility model is provided with a knock-down through plate 13 on both the first side and the second side, a through plate 13 is provided with a wire threading hole, and the design of two different through plates 13 on the same side are not connected, when only a single group of wires needs to be connected to the access box body 1, the user only needs to knock down the threading plate 12; and when multiple groups of wires need to be connected to the access box body 1 from the same direction at the same time, the user knocks down the through plate 13 at this direction, and the multiple groups of wires pass through the through holes of the knocked-down through plate 13; thereby solving the problem in the prior art that multiple wiring boxes are buckled together in series, and the lines are easily confused when multiple groups of wires are connected to and taken out of the switch panel from the same direction. At the same time, the wires in the box body 1 cannot enter the gap between the lower surface of the panel mounting ear 2 and the upper surface of the wire blocking column 6, that is, the gap between the lower surface of the panel mounting ear 2 and the upper surface of the wire blocking column 6 is smaller than the diameter of the wire, thereby preventing the surface layer of the wire from being damaged by the screws; the wire blocking column 6 is located between two different through plates 13 on the same side, and the wire blocking column 6 abuts against the first side and the second side of the wiring dark box, thereby strengthening the firmness of the wiring dark box. In addition, a blocking piece 7 for closing the main threaded hole 31 is provided above the panel mounting ear 2. When installing the wiring dark box, the blocking piece 7 is closed, thereby preventing the main threaded hole 31 in the wiring dark box used to cooperate with the screw from entering mud and sand during use, resulting in failure to cooperate with the screw, thereby causing the problem that the panel cannot be fixed on the wiring dark box; after the wiring dark box is installed, the blocking piece 7 is opened again to ensure that the main threaded hole 31 can smoothly cooperate with the screw, and the panel is fixed on the box body 1. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
