Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and more specifically to an electricity meter flip cover and an electricity meter. Background Technology

[0002] In related technologies, the rotating shaft of the flip cover of the electricity meter needs to withstand a large force. Therefore, a nested metal rotating shaft is generally used to improve the strength of the rotating shaft. However, the metal rotating shaft increases the number of assembly steps, resulting in increased process costs, and the metal rotating shaft is also subject to the risk of corrosion. Utility Model Content

[0003] The present invention aims to at least solve or improve the technical problems in the related art where the flip cover of the electricity meter needs to be nested with a metal shaft, which leads to increased cost of the electricity meter and easy corrosion of the shaft.

[0004] Therefore, the first aspect of this utility model provides a flip cover for an electricity meter.

[0005] A second aspect of this utility model provides an electricity meter.

[0006] In view of the above, according to the first aspect of the present invention, the present invention provides a flip cover for an electricity meter, comprising: a cover body, the cover body including a cover plate, a first side plate and a second side plate, the first side plate and the second side plate being disposed on the same side of the cover plate and disposed opposite to each other; a first rotating shaft disposed on the side of the first side plate away from the second side plate, the first rotating shaft and the cover body being integrally injection molded, the side of the first rotating shaft away from the first side plate having a first material removal hole; and a second rotating shaft disposed on the side of the second side plate away from the first side plate, the second rotating shaft and the cover body being integrally injection molded, the side of the second rotating shaft away from the second side plate having a second material removal hole.

[0007] The flip cover of the electricity meter proposed in this utility model includes a cover body, a first rotating shaft and a second rotating shaft. The cover body, the first rotating shaft and the second rotating shaft are integrally injection molded, which eliminates the need for nested metal rotating shafts, reduces assembly steps, lowers production costs and reduces the risk of corrosion of the first rotating shaft and the second rotating shaft.

[0008] The cover includes a cover plate, a first side plate, and a second side plate. The first side plate and the second side plate are both located on the same side of the cover plate and are arranged opposite to each other. The first rotating shaft and the first side plate are integrally injection molded, and the second rotating shaft and the second side plate are integrally injection molded. The first rotating shaft is located on the side of the first side plate away from the second side plate, and the second rotating shaft is located on the side of the second side plate away from the first side plate. Through the above structure, it is ensured that the first rotating shaft and the second rotating shaft can be coaxial, so as to ensure the reliability of the rotation of the flip cover of the electricity meter.

[0009] The first rotating shaft has a first material removal hole on the side opposite to the first side plate, which reduces the wall thickness of the first rotating shaft, thereby reducing the possibility of shrinkage of the first rotating shaft after injection molding, improving the reliability of the first rotating shaft, and improving the yield of the flip cover of the electricity meter.

[0010] The second rotating shaft has a second material removal hole on the side opposite to the second side plate, thereby reducing the wall thickness of the second rotating shaft, which in turn reduces the possibility of shrinkage of the second rotating shaft after injection molding, improves the reliability of the second rotating shaft, and improves the yield of the flip cover of the energy meter.

[0011] In some technical solutions, optionally, the first material removal hole is located at the center of the first rotating shaft, and the first rotating shaft and the first material removal hole are coaxially arranged; the second material removal hole is located at the center of the second rotating shaft, and the second rotating shaft and the second material removal hole are coaxially arranged.

[0012] In this technical solution, the first material feeding hole is located at the center of the first rotating shaft, and the first rotating shaft and the first material feeding hole are coaxial, thereby making the wall thickness of the first rotating shaft more uniform and further reducing the possibility of shrinkage of the first rotating shaft.

[0013] The second material outlet is located at the center of the second rotating shaft, and the second rotating shaft and the second material outlet are coaxial, which makes the wall thickness of the second rotating shaft more uniform and further reduces the possibility of shrinkage of the second rotating shaft.

[0014] In some technical solutions, optionally, the first material discharge hole extends from the center of the first rotating shaft to the outer wall of the first rotating shaft; the second material discharge hole extends from the center of the second rotating shaft to the outer wall of the second rotating shaft.

[0015] In this technical solution, the first material feeding hole is not only located at the center of the first rotating shaft, but also extends from the center of the first rotating shaft to the outer wall of the first rotating shaft, that is, making the first rotating shaft form a "C" shaped structure, thereby making the wall thickness of the first rotating shaft more uniform, further reducing the possibility of shrinkage of the first rotating shaft, reducing the material used in the first rotating shaft, and reducing production costs.

[0016] The second material outlet is not only located at the center of the second shaft, but also extends from the center of the second shaft to the outer wall of the second shaft, which makes the second shaft form a "C" shaped structure. This makes the wall thickness of the second shaft more uniform, further reduces the possibility of shrinkage of the second shaft, and reduces the material used for the second shaft, thereby reducing production costs.

[0017] In some technical solutions, optionally, the first rotating shaft forms a first chamfer towards the edge of the first side plate; the second rotating shaft forms a second chamfer towards the edge of the second side plate.

[0018] In this technical solution, the edge of the first rotating shaft facing the first side plate forms a first chamfer, which facilitates the demolding of the flip cover of the energy meter and reduces the possibility of breakage of the first rotating shaft and the first side plate.

[0019] The second rotating shaft forms a second chamfer on the edge of the side facing the second side plate, which facilitates the demolding of the flip cover of the energy meter and reduces the possibility of breakage of the second rotating shaft and the second side plate.

[0020] In some technical solutions, optionally, the first rotating shaft forms a third chamfer away from the edge of the first side plate; the second rotating shaft forms a fourth chamfer away from the edge of the second side plate.

[0021] In this technical solution, the edge of the first rotating shaft opposite to the first side plate forms a third chamfer, which facilitates the insertion of the first rotating shaft into the corresponding first shaft hole and reduces the installation difficulty.

[0022] The edge of the second shaft opposite to the second side plate forms a fourth chamfer, which facilitates the insertion of the second shaft into the corresponding second shaft hole and reduces the difficulty of installation.

[0023] In some technical solutions, optionally, the diameter of the first rotating shaft is greater than or equal to 2 mm; the diameter of the second rotating shaft is greater than or equal to 2 mm.

[0024] In this technical solution, the diameter of the first rotating shaft is greater than or equal to 2mm, thereby increasing the strength of the first rotating shaft and reducing the possibility of the first rotating shaft breaking.

[0025] The diameter of the second shaft is greater than or equal to 2mm, thereby increasing the strength of the second shaft and reducing the possibility of breakage.

[0026] In some technical solutions, the cover plate can optionally be a bent structure, with the first side plate and the second side plate located inside the cover plate.

[0027] In this technical solution, the cover plate has a bent structure, making the flip cover of the electricity meter a three-dimensional cover, which facilitates the sliding off of water droplets and improves the protective effect of the flip cover on the electricity meter. In addition, the first side plate and the second side plate are located on the inner side of the cover plate, so that the outer side of the cover plate can form a smooth surface, which is more conducive to the maintenance of the flip cover of the electricity meter and prevents the flip cover of the electricity meter from scratching other objects.

[0028] In some technical solutions, the cover plate may optionally include: a first plate; an arc-shaped plate, one end of which is connected to the first plate; a second plate, which is connected to the other end of the arc-shaped plate; the first plate, the arc-shaped plate, and the second plate are integrally injection molded; and the first side plate and the second side plate are both connected to the first plate, the arc-shaped plate, and the second plate.

[0029] In this technical solution, the cover plate includes a first plate and a second plate, which form a certain angle. The first plate and the second plate are connected by an arc-shaped plate, which is located at both ends of the arc-shaped plate. This reduces the sharp edges of the outer surface of the cover plate. Furthermore, the arc-shaped plate facilitates the rotation of the flip cover of the electricity meter, which helps to reduce the interference between the flip cover of the electricity meter and the main body of the electricity meter.

[0030] Furthermore, the first plate, the arc-shaped plate, and the second plate are integrally injection molded, which can reduce the production steps of the flip cover of the electricity meter and reduce production costs.

[0031] In some technical solutions, optionally, the first rotating shaft is located at a position opposite to the first side plate and the arc-shaped plate; the second rotating shaft is located at a position opposite to the second side plate and the arc-shaped plate.

[0032] In this technical solution, the first rotating shaft is positioned opposite to the first side plate and the arc-shaped plate, so that the first rotating shaft is approximately located at one end of the first plate, thereby reducing interference to the main body of the energy meter when the flip cover of the energy meter rotates.

[0033] The second rotating shaft is positioned opposite the second side plate and the arc-shaped plate, so that the second rotating shaft is approximately located at one end of the first plate, reducing interference to the main body of the energy meter when the flip cover of the energy meter rotates.

[0034] According to a second aspect of the present invention, an electricity meter is provided, comprising: a main body; and a flip cover of the electricity meter as provided in the first aspect embodiment, wherein the flip cover and the main body are rotatably connected by a first rotating shaft and a second rotating shaft.

[0035] The energy meter proposed in this utility model includes the flip cover of the energy meter as proposed in the first aspect embodiment, and therefore has all the beneficial effects of the flip cover of the energy meter as proposed in the first aspect embodiment, which will not be described in detail here.

Specifically, the first side of the cover plate 112 is the outer side, and the second side of the cover plate 112 is the inner side.

[0054] The flip cover 100 of the electricity meter provided by this utility model includes a cover body 110, a first rotating shaft 130 and a second rotating shaft 140. The cover body 110, the first rotating shaft 130 and the second rotating shaft 140 are integrally injection molded, which eliminates the need for nested metal rotating shafts, reduces assembly steps, lowers production costs, and reduces the risk of corrosion of the first rotating shaft 130 and the second rotating shaft 140.

[0055] The cover 110 includes a cover plate 112, a first side plate 120, and a second side plate 122.

The first plate 114 and the second plate 118 are respectively located at both ends of the arc-shaped plate 116, thereby reducing the sharp edges of the outer surface of the cover plate 112. Furthermore, the arc-shaped plate 116 facilitates the rotation of the flip cover 100 of the energy meter, which helps to reduce the interference between the flip cover 100 of the energy meter and the main body 210 of the energy meter 200.

[0086] Furthermore, the first plate 114, the arc-shaped plate 116, and the second plate 118 are integrally injection molded, which can reduce the production steps of the flip cover 100 of the electricity meter and reduce production costs.
