Technical Field

[0001] The utility model relates to the technical field of electrical appliance boxes, and specifically relates to a metering box for an electric meter. Background Art

[0002] In the existing electric meter metering boxes, such as the publication number: CN117578204A or the publication number: CN117420340A; during installation, the back of the box body directly contacts the wall surface. In order to improve the stability of the box body, after the box body is connected to the wall surface, the expansion bolts reserved on the wall surface are tightened to closely attach the back of the box body to the wall surface.

[0003] After the box body is closely attached to the wall surface, on the one hand, the friction between the box body and the wall surface during the installation process causes damage to the paint on the outer wall of the box body; on the other hand, with the box body closely attached to the wall surface, rainwater carries impurities such as sand and lime on the wall surface and seeps into the back of the box body, which will also cause the box body to be corroded and affect its service life; thirdly, the heat source inside the box body cannot be discharged in all directions, which will also affect the use of the electrical equipment inside the box body. Content of the Utility Model

[0004] The purpose of the utility model is to provide a metering box for an electric meter to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A metering box for an electric meter, comprising a box body and a connecting plate installed on the wall surface; an installation seat is further provided on the box body, and the installation seat is connected to the connecting plate through a provided connecting piece; the connecting piece includes a first connecting portion and a second connecting portion, and is connected to the installation seat by passing a provided fastener through the first connecting portion, so that the second connecting portion is inserted into a connecting frame provided on the connecting plate; through the connection of the connecting piece with the box body and with the connecting plate, an air flow channel is formed between the box body and the connecting plate.

[0006] As a preferred technical solution of the utility model: A notch is further provided on the second connecting portion, and the notch slides along a convex block provided on the connecting plate.

[0007] As a preferred technical solution of the utility model: A waist-shaped groove is further provided on the connecting plate.

[0008] As a preferred technical solution of the utility model: The first connecting portion and the second connecting portion are arranged in a plate shape, and the cross-section of the first connecting portion and the second connecting portion is L-shaped.

[0009] As a preferred technical solution of the utility model: The material of the connecting plate is stainless steel.

[0010] With the above technical solution, the beneficial effects of the present utility model are as follows: After the connecting member is connected to the mounting seat and the connecting plate, an air flow channel is formed between the box body and the connecting plate. Due to the formation of the air duct, on the one hand, it is convenient for air flow to take away the heat between the box body and the connecting plate, so that the back surface of the box body can also dissipate heat during operation, and thus heat sources can be radiated outward from all surfaces of the box body; on the other hand, the formation of the air duct will not block impurities such as sand and water source, thereby reducing the problem that the box body is easily corroded due to the combined action of corrosion components and heat sources in water vapor and sand on the box body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0018] Please refer to Figures 1-5The utility model provides an embodiment: a meter box for an electric meter, comprising a box body 1 and a connecting plate 2 installed on a wall; a mounting seat 4 is also provided on the box body 1, and the mounting seat 4 is connected to the connecting plate 2 through a connecting piece 6; the connecting piece 6 comprises a first connecting portion 10 and a second connecting portion 11, and is connected to the mounting seat 4 after passing through the first connecting portion 10 through a fastener 5 provided, so that the second connecting portion 11 is inserted into a connecting frame 7 provided on the connecting plate 2; the connecting piece 6 is connected to the box body 1 and the connecting plate 2, so that an air flow channel 3 is formed between the box body 1 and the connecting plate 2.

[0019] In summary, after the connecting plate 2 is connected to the wall, the connecting member 6 is then installed on the connecting seat from the side of the box body 1 through the fastener 5; after the connecting member 6 is assembled with the mounting seat, the second connecting portion 11 is aligned with the connecting frame 7, and then the fastener 5 is tightened to insert the second connecting portion 11 into the connecting frame 7, thereby completing the assembly of the box body 1 and the connecting plate 2. The fastener 5 is preferably a bolt, and is threadedly matched with the internal threaded hole provided on the mounting seat 4; in addition, the connecting member 6 and the mounting seat 4 are perpendicular to the wall, so it is convenient to install the fastener 5 from the side of the box body 1, and then when the fastener 5 is tightened, the back of the hand or the palm of the hand will not face the wall, thereby reducing the problem of the back of the hand or fingers being scratched by the wall during the tightening of the fastener 5.

[0020] In particular, due to the formation of the airway, on the one hand, it is convenient for airflow to flow to take away the heat between the box body 1 and the connecting plate 2, so that the back side of the box body 1 can also dissipate heat when working, and then all surfaces of the box body 1 can radiate heat source outward; on the other hand, the formation of the airway will not block impurities such as sand and gravel, water source, etc., thereby reducing the problem of the box body being easily corroded due to the combined effect of water vapor, corrosive components in sand and gravel and heat source on the box body.

[0021] Furthermore, since a notch 12 is provided on the second connection part 11, and the notch 12 slides along the protrusion 9 provided on the connection plate 2, the protrusion 9 cooperates with the notch 12 to guide the second connection part 11 to be smoothly inserted into the connection frame 7. At the same time, when the second connection part 11 is connected to the connection frame 7, the protrusion 9 can also support the second connection part 11 to ensure that the second connection part 11 will not easily break or bend to one side after being subjected to force.

[0022] In addition, since the waist-shaped groove 8 is also provided on the connecting plate 2, the difficulty of connecting the connecting plate 2 with the expansion bolt is reduced.

[0023] Based on the above solution, since the first connecting portion 10 and the second connecting portion 11 are arranged in a plate shape, and the cross-section of the first connecting portion 10 and the second connecting portion 11 is L-shaped, it is convenient for the connector 6 to achieve surface-to-surface contact with the mounting seat 4 and between the connector 6 and the connecting plate 2, so as to improve the stability after the box body 1 is connected to the connecting plate 2.

[0024] Furthermore, since the material of the connecting plate 2 is stainless steel, the corrosion rate of the connecting plate 2 can be delayed, and thus the service life of the connecting plate 2 can be extended.

[0025] In summary, by optimizing the structure of the connection between the box body 1 and the wall surface, the corrosion resistance of the box body 1 can be extended without changing the coating on the outer wall surface of the existing box body 1.

[0026] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
