Description

Technical Field

[0001] This invention relates to the field of electricity metering box door technology, and in particular to a fixing structure for the window of an electricity metering box. Background Technology

[0002] Electricity metering boxes are essential basic protective equipment in power distribution systems, widely used in various electricity consumption scenarios such as residential buildings, commercial buildings, industrial parks, and municipal infrastructure. They primarily encapsulate and protect electricity meters and their wiring components, preventing damage from the external environment and human contact, while ensuring the safety and convenience of power maintenance and data reading. To allow for direct observation of the meter's operating status, reading meter data, and checking indicator light status without opening the metering box door, as well as facilitating card-based electricity purchases, existing electricity metering boxes feature a transparent observation window on their door surface—an indispensable functional structure.

[0003] To avoid glare and unclear readings caused by strong light in outdoor and corridor environments, most electricity metering boxes are equipped with a flip-up sunshade on the outside of the window. This sunshade improves the clarity of the reading by blocking direct sunlight, while also protecting the transparent window from dust accumulation, rain erosion, and damage from external impacts. This greatly improves the environmental adaptability and ease of use of the electricity metering box, and this structure has been widely used in residential, commercial, and industrial power distribution boxes.

[0004] In existing technologies, traditional electricity metering box window sunshade structures often employ a separate design with a single flip-up sunshade and an independent card slot cover. Both the sunshade and the card slot cover are freely flip-up structures without any positioning support or self-locking mechanism. In conventional solutions, the sunshade is only opened and closed via a top hinge, and there is no fixed limiting structure after it is opened. It relies entirely on manual holding to maintain the open state, which is cumbersome and cannot meet the needs for quick and convenient reading and observation. When inserting or retrieving the meter card, both the sunshade and the card slot cover must be lifted simultaneously, and both must be manually maintained in their open position. This is difficult to complete with one hand, and the cover and sunshade are prone to falling back and obstructing the operating area, seriously affecting the efficiency of card insertion. Summary of the Invention

[0005] The purpose of this invention is to provide a fixed structure for the window of an electricity metering box, which solves the technical problems of existing technologies, such as the inability to read data quickly and conveniently, and the low efficiency during card insertion operations.

[0006] To solve the above-mentioned technical problems, the present invention provides a window fixing structure for an electricity metering box, which is installed on the cabinet door of the electricity metering box and includes a sunshade, a cover plate, a hinge shaft and a transparent window; The cabinet door is provided with a window, and a transparent window is provided at the window, and the transparent window is connected to the cabinet door; The hinge shaft is located on the side of the sunshade, the sunshade is connected to the hinge shaft, and the hinge shaft is hinged to the transparent window, so that the sunshade can rotate relative to the transparent window through the hinge shaft, thereby allowing the sunshade to cover the window. The cover plate is hinged to the transparent window, and the cover plate is used to cover the operating gap of the transparent window; After the sunshade is rotated and opened, the end of the sunshade abuts against and presses against the transparent window, and as the sunshade rotates to an angle of less than or equal to 90° with the cabinet door, the pressing force between the sunshade and the transparent window increases. As the sunshade rotates to an angle exceeding 90° with the cabinet door, the pressure between the sunshade and the transparent window decreases. A protrusion is provided below the sunshade, and the end of the cover plate opposite to the transparent window is engaged with the protrusion, so that the sunshade presses the cover plate through the protrusion, and the sunshade, the cover plate and the transparent window form a triangle.

[0007] In an optional embodiment, the sunshade, the cover, and the transparent window form an acute triangle.

[0008] In an optional embodiment, a positioning post is provided on the sunshade, and a positioning hole is provided on the cabinet door; The positioning post is adapted to the positioning hole, and when the sunshade covers the transparent window, the positioning post is inserted into the positioning hole.

[0009] In an optional embodiment, two hinge shafts are provided on the side of the sunshade facing away from the ground, and the two hinge shafts are respectively provided on both sides of the sunshade.

[0010] In an optional embodiment, two hinge shafts are respectively inserted into the connecting posts on the transparent window, so that when the sunshade covers the transparent window, the surface of the sunshade is flush with the surface of the cabinet door.

[0011] In an alternative embodiment, the side of the cover plate facing away from the ground is hinged to the transparent window.

[0012] In an optional embodiment, a handle is provided on the side of the sunshade closest to the ground, and the handle is integrally formed with the sunshade.

[0013] In an optional embodiment, the end of the sunshade near the transparent window is rounded.

[0014] In an optional embodiment, the sunshade is provided with a flange at one end of the sunshade near the transparent window. The flange is perpendicular to the sunshade and extends along the width direction of the sunshade. The sunshade presses against the transparent window through the flange.

[0015] In an optional embodiment, the length of the flange is less than the width of the sun visor, and the two ends of the flange are respectively spaced apart from the edge of the sun visor.

[0016] This invention provides a window fixing structure for an electricity metering box, installed on the cabinet door of the electricity metering box, including a sunshade, a cover plate, a hinge shaft, and a transparent window; the cabinet door has a window, and the transparent window covers the window and is connected to the cabinet door; the hinge shaft is located on the side of the sunshade, the sunshade is connected to the hinge shaft, and the hinge shaft is hinged to the transparent window, allowing the sunshade to rotate relative to the transparent window via the hinge shaft, thus allowing the sunshade to cover the window; the cover plate is hinged to the transparent window and is used to cover the operation of the transparent window. The sunshade is positioned at the gap; after it is rotated and opened, the end of the sunshade abuts against and presses against the transparent window. As the sunshade rotates to an angle of less than or equal to 90° with the cabinet door, the pressure between the sunshade and the transparent window increases; as the sunshade rotates to an angle of more than 90° with the cabinet door, the pressure between the sunshade and the transparent window decreases. A protrusion is provided below the sunshade, and the end of the cover plate away from the transparent window is engaged with the protrusion, so that the sunshade presses against the cover plate through the protrusion, and the sunshade, cover plate and transparent window form a triangle. When the sun visor needs to be opened separately, it can be rotated more than 90°, thus fixing it in place by contact with the transparent window. This avoids the need for prolonged hand-holding of the sun visor. The triangle formed by the cover plate, the protrusions on the sun visor, and the transparent window secures the cover plate, transparent window, and sun visor, facilitating cover plate fixation and card insertion. This solves the technical problems of existing technologies, such as the inability to quickly and conveniently read data and the low efficiency during card insertion. It achieves the technical effect of more convenient and faster data reading and more convenient and efficient card insertion. Attached Figure Description

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] In related technologies, traditional electricity metering box window sunshade structures often employ a separate design with a single flip-up sunshade and an independent card slot cover. Both the sunshade and the card slot cover are freely flip-up structures without positioning support or self-locking mechanisms. In conventional solutions, the sunshade is only opened and closed via a top hinge, and there is no fixed limiting structure after it is opened. It relies entirely on manual holding to maintain the open state, making operation cumbersome and failing to meet the needs for quick and convenient reading and observation. When inserting or retrieving the meter card, both the sunshade and the card slot cover must be lifted simultaneously, and both must be manually maintained in their open position. This is difficult to complete with one hand, and the cover and sunshade are prone to falling back and obstructing the operating area, severely affecting the efficiency of card insertion.

[0022] In view of this, such as Figures 1-4As shown, some embodiments of the present invention provide a window fixing structure for an electricity metering box, installed on the cabinet door 5 of the electricity metering box, including a sunshade 1, a cover plate 2, a hinge shaft 3, and a transparent window 4; the cabinet door 5 is provided with a window, and the transparent window 4 covers the window and is connected to the cabinet door 5; the hinge shaft 3 is provided on the side of the sunshade 1, the sunshade 1 is connected to the hinge shaft 3, and the hinge shaft 3 is hinged to the transparent window 4, so that the sunshade 1 can rotate relative to the transparent window 4 through the hinge shaft 3, thereby allowing the sunshade 1 to cover the window; the cover plate 2 is hinged to the transparent window 4, and the cover plate 2 is used to cover the transparent window 4. On the operating gap of the transparent window 4; after the sunshade 1 is rotated and opened, the end of the sunshade 1 abuts and presses against the transparent window 4, and the pressing force between the sunshade 1 and the transparent window 4 increases as the sunshade 1 rotates to an angle of less than or equal to 90° with the cabinet door 5; as the sunshade 1 rotates to an angle of more than 90° with the cabinet door 5, the pressing force between the sunshade 1 and the transparent window 4 decreases; a protrusion 6 is provided below the sunshade 1, and the end of the cover plate 2 away from the transparent window 4 is engaged with the protrusion 6, so that the sunshade 1 presses against the cover plate 2 through the protrusion 6, and the sunshade 1, the cover plate 2 and the transparent window 4 form a triangle.

[0023] In the above embodiments, the sunshade 1 can be made of metal or opaque plastic. The sunshade 1 can be rectangular, while the cabinet door 5 can be made of metal. The cabinet door 5 can have a rectangular window, and the sunshade 1 is correspondingly placed over the window to seal it. The cover plate 2 and the transparent window 4 can both be made of transparent plastic to avoid obstructing the reading of the internal electricity meter. The cover plate 2 is set on the outer surface of the transparent window 4. The cover plate 2 can be hinged to the transparent window 4 through a pin, thereby sealing the operating gap on the transparent window 4. When it is necessary to insert a card or press a button, the operating gap can be opened by rotating the cover plate 2 to facilitate the insertion of a card or pressing of a button.

[0024] After the sunshade 1 is hinged to the transparent window 4 via the hinge shaft 3, when the sunshade 1 is raised, the end of the sunshade 1 closest to the transparent window 4 moves closer to the transparent window 4 until it contacts the transparent window 4. Under the action of the hinge shaft 3, the sunshade 1 begins to abut and press against the transparent window 4, causing the sunshade 1 and the transparent window 4 to undergo elastic deformation under the action of the materials. Before rotating to 90°, the sunshade 1 tends to cover the transparent window 4 until the angle between the sunshade 1 and the transparent window 4 reaches 90°. At this point, the compressive force between the transparent window 4 and the sunshade 1 is at its maximum. Then, as the sunshade 1 continues to rotate to an angle exceeding 90° with the transparent window 4, the pressure increases. The pressure between the transparent window 4 and the sunshade 1 decreases. At this time, through the contact between the transparent window 4 and the sunshade 1, and in conjunction with the hinge shaft 3, the sunshade 1 can overcome gravity and remain open, thus eliminating the need for manual holding of the sunshade 1 for extended periods. When the sunshade 1, transparent window 4, and cover plate 2 form a triangular structure, the angle of rotation of the sunshade 1 is acute. At this time, due to the elastic deformation of the sunshade 1 and transparent window 4, the sunshade 1 has a tendency to close tightly onto the transparent window 4. Thus, the sunshade 1 can be pressed tightly onto the cover plate 2 through the protrusion 6, making the sunshade 1, transparent window 4, and cover plate 2 form a stable triangle, thereby facilitating the operator to insert cards, press buttons, and perform other operations through the operating gap.

[0025] Optionally, the operating gap can be a vertical strip to align with the card slot on the meter, facilitating card insertion. Alternatively, the operating gap can be an oval hole, allowing the operator to access the meter's buttons through it. Or, the operating gap can be a combination of a strip and an oval hole, simultaneously accommodating card insertion and button operation. Correspondingly, the cover plate 2 is shaped to fit the strip or oval hole, ensuring it fits snugly over the opening.

[0026] Alternatively, a hinge hole is provided on the side of the sunshade 1. The hinge hole is circular, and a hinge shaft 3 is provided on the transparent window 4. The hinge shaft 3 is fitted onto the hinge hole on the sunshade 1 to achieve the hinge between the sunshade 1 and the transparent window 4.

[0027] Some embodiments of the present invention provide a window fixing structure for an electricity metering box, installed on the cabinet door 5 of the electricity metering box, including a sunshade 1, a cover plate 2, a hinge shaft 3, and a transparent window 4; the cabinet door 5 is provided with a window, and the transparent window 4 covers the window and is connected to the cabinet door 5; the hinge shaft 3 is located on the side of the sunshade 1, the sunshade 1 is connected to the hinge shaft 3, and the hinge shaft 3 is hinged to the transparent window 4, so that the sunshade 1 can rotate relative to the transparent window 4 through the hinge shaft 3, thereby allowing the sunshade 1 to cover the window; the cover plate 2 is hinged to the transparent window 4, and the cover plate 2 is used to cover the transparent window 4. On the operating gap of window 4; after the sunshade 1 is rotated and opened, the end of the sunshade 1 abuts and presses against the transparent window 4, and the pressing force between the sunshade 1 and the transparent window 4 increases as the sunshade 1 rotates to an angle of less than or equal to 90° with the cabinet door 5; as the sunshade 1 rotates to an angle of more than 90° with the cabinet door 5, the pressing force between the sunshade 1 and the transparent window 4 decreases; a protrusion 6 is provided below the sunshade 1, and the end of the cover plate 2 away from the transparent window 4 is engaged with the protrusion 6, so that the sunshade 1 presses against the cover plate 2 through the protrusion 6, and the sunshade 1, the cover plate 2 and the transparent window 4 form a triangle. When the sunshade 1 needs to be opened alone, it can be rotated more than 90°, so that the sunshade 1 is fixed by its contact with the transparent window 4, avoiding the need to hold the sunshade 1 by hand for a long time. The triangle formed by the cover plate 2, the protrusion 6 on the sunshade 1 and the transparent window 4 can fix the cover plate 2, the transparent window 4 and the sunshade 1, making it easy to fix the cover plate 2 and convenient to insert cards. This solves the technical problems of the existing technology that it is not possible to read the data quickly and conveniently and that the card insertion operation is inefficient. It achieves the technical effect of more convenient and faster reading and more convenient and efficient card insertion operation.

[0028] In an optional embodiment, the sunshade 1, cover plate 2, and transparent window 4 form an acute triangle.

[0029] In an alternative embodiment, the side of the cover plate 2 facing away from the ground is hinged to the transparent window 4.

[0030] In the above embodiment, the upper end of the cover plate 2 is hinged to the transparent window 4, so that the cover plate 2 can be placed on the transparent window 4 under the action of gravity. When the cover plate 2 can be rotated to form an obtuse angle with the transparent window 4, the end of the cover plate 2 away from the transparent window 4 is engaged with the protrusion 6 of the sunshade 1. At this time, the cover plate 2, the sunshade 1 and the transparent window 4 form an acute triangle, which makes the cover plate 2, the sunshade 1 and the transparent window 4 more stable. At the same time, the cover plate 2 can avoid the operating gap, making it convenient for users to insert cards, press buttons and other operations.

[0031] In an optional embodiment, a positioning post 7 is provided on the sunshade 1 and a positioning hole is provided on the cabinet door 5; the positioning post 7 is adapted to the positioning hole, and when the sunshade 1 covers the transparent window 4, the positioning post 7 is inserted into the positioning hole.

[0032] In the above embodiments, the positioning post 7 can be cylindrical, and there can be one or more positioning posts 7. The multiple positioning posts 7 are symmetrically arranged on the side of the sunshade 1 facing the transparent window 4. The multiple positioning posts 7 correspond to multiple positioning holes, which can be set on the transparent window 4. When the sunshade 1 covers the transparent window 4, the multiple positioning posts 7 on the sunshade 1 are respectively inserted into the multiple positioning holes, thereby positioning the sunshade 1 and limiting the movement of the sunshade 1.

[0033] In an optional embodiment, two hinge shafts 3 are provided on the side of the sunshade 1 facing away from the ground, and the two hinge shafts 3 are respectively provided on both sides of the sunshade 1.

[0034] In an optional embodiment, two hinge shafts 3 are respectively inserted into the connecting post 8 on the transparent window 4, so that when the sunshade 1 covers the transparent window 4, the surface of the sunshade 1 is flush with the surface of the cabinet door 5.

[0035] Optionally, two hinge shafts 3 can be provided on the transparent window 4. The two hinge shafts 3 are integrally formed with the connecting column 8. A hinge hole can be provided on each side of the sunshade 1. The two hinge holes are respectively fitted onto the two hinge shafts 3, thereby realizing the hinge between the sunshade 1 and the transparent window 4.

[0036] In the above embodiment, a hinge shaft 3 is provided on each side of the sunshade 1. The hinge shaft 3 can be cylindrical. The sunshade 1 can be integrally formed with the hinge shaft 3. Two connecting posts 8 are provided on the outer surface of the transparent window 4. The two connecting posts 8 are rotatably connected to the two hinge shafts 3 respectively, so that the sunshade 1 can rotate relative to the transparent window 4.

[0037] In an optional embodiment, a handle 9 is provided on the side of the sunshade 1 closest to the ground, and the handle 9 is integrally formed with the sunshade 1.

[0038] In the above embodiment, the handle 9 can be integrally formed with the sun visor 1. The handle 9 can be recessed inward. The handle 9 can be located on the side of the sun visor 1 away from the connecting column 8. The handle 9 can be in a recessed shape so that the operator can reach into the handle 9 and turn the sun visor 1 by the handle 9 to make the sun visor 1 start to rotate.

[0039] In an optional embodiment, the end of the sunshade 1 near the transparent window 4 is rounded.

[0040] In the above embodiment, the side of the sunshade 1 that contacts the transparent window 4 is set with a rounded corner. The rounded corner can make the rotation of the sunshade 1 and the transparent window 4 smoother. Even when the sunshade 1 presses against the transparent window 4, the rotation of the sunshade 1 can be smoother. At the same time, when the rotation angle of the sunshade 1 is less than 90°, the sunshade 1 can have a tendency to move and cover the transparent window 4 through the pressure between the transparent window 4 and the sunshade 1, so that the sunshade 1 can be pressed against the cover plate 2 by the protrusion 6.

[0041] In an optional embodiment, a flange 10 is provided on the sunshade 1. The flange 10 is located at one end of the sunshade 1 near the transparent window 4. The flange 10 is perpendicular to the sunshade 1 and extends along the width direction of the sunshade 1. The sunshade 1 presses the transparent window 4 through the flange 10.

[0042] In the above embodiments, the flange 10 can be integrally formed with the sunshade 1. The flange 10 can be elongated and can be located at the contact point between the sunshade 1 and the transparent window 4. The flange 10 can extend along the width direction of the sunshade 1, so that the sunshade 1 can contact the transparent window 4 through the flange 10. When the sunshade 1 is placed on the transparent window 4, the flange 10 can be located on the side of the sunshade 1 facing the transparent window 4, so that the flange 10 can be hidden, making the overall appearance more aesthetically pleasing.

[0043] In an optional embodiment, the length of the flange 10 is less than the width of the sun visor 1, and the two ends of the flange 10 are respectively spaced apart from the edge of the sun visor 1.

[0044] In the above embodiment, the length of the flange 10 is less than the width of the sunshade 1, and the flange 10 can be in the form of a reinforcing rib. There is a gap between the flange 10 and the edge of the sunshade 1, so that when the sunshade 1 is pressed against the transparent window 4, only the flange 10 contacts the transparent window 4, effectively controlling the pressing force between the sunshade 1 and the transparent window 4, while avoiding large-area deformation of the sunshade 1 that could cause material fatigue.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
