Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to an electric energy meter sealing cover. Background Art

[0002] An energy meter is an instrument used to measure the consumption of electrical energy and is usually installed in residential, commercial buildings or industrial facilities. It records the use of electrical energy supplied by the power grid for billing and monitoring of energy consumption. An energy meter usually consists of the following main parts: Dial: A number or pointer that displays the amount of energy used, usually in kilowatt-hours. Metering device: Measures current and voltage to calculate the amount of energy used. Housing: Protects the internal components of the energy meter from the external environment. Terminal blocks: Used to connect the energy meter to the power line. Sealing screws: Used to seal the housing of the energy meter to prevent unauthorized personnel from interfering. The energy meter calculates the amount of energy used by monitoring the changes in current and voltage. When current passes through the energy meter, a magnetic field is generated, which, according to Faraday's law of electromagnetic induction, causes a current to be generated. By measuring the size and duration of this current, the energy meter can accurately calculate the amount of energy used. The energy meter plays a vital role in modern society. It is not only used for billing and settlement of electricity bills, but also helps users monitor and manage energy consumption, promote energy conservation and sustainable development.

[0003] After searching, the Chinese patent publication number CN216209380U discloses an electric energy meter with a cover structure, including an upper cover and a base, which also includes a cover. The base is provided with a terminal and a first fastening hole, and an annular groove and two concave cavities are provided on the side of the upper cover close to the terminal. The concave cavities are located at both ends of one side of the upper cover, and the concave cavities are far away from the terminal relative to the annular groove; the cover is provided with an annular rib adapted to the annular groove, a protrusion cooperating with the concave cavity, and a second fastening hole coaxially arranged with the first fastening hole.

[0004] However, in actual practice, it was found that when the electricity meters are fixed with lead sealing screws, when the power supply bureau's metering center calibrates the meters, most of the electricity meters are hung on the wall or on the installation panel, the lead sealing screws must be unscrewed and the cover must be removed before calibration. After calibration, the terminal cover must be installed again. In this way, it is easy to lose the lead sealing screws or the cover during the disassembly process, causing unnecessary losses. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that lead sealing screws or sealing covers are easily lost during the disassembly process, and proposes an electric energy meter sealing cover.

[0014] Beneficial effects:

[0015] 1. The electric energy meter cover can magnetically limit the lead sealing screw through the magnetic cooperation between the magnetic block and the end of the lead sealing screw, thereby reducing the number of times the lead sealing screw is lost when the cover is removed;

[0016] 2. The electric energy meter cover can store and limit the cover by using the locking column, thereby reducing the number of times the cover is lost, effectively storing and limiting the cover, and preventing unnecessary losses;

[0026] Example:

[0027] Reference Figure 1-Figure 4, an electric energy meter cover, including a shell 1 with an electric energy component. The electric energy component in a general electric energy meter mainly includes the following main parts: Dial: a number or pointer that displays the amount of electric energy used, usually in kilowatt-hours. Metering device: measures current and voltage to calculate the amount of electric energy used. Casing: protects the internal components of the electric energy meter from the influence of the external environment. Terminal blocks: used to connect the electric energy meter to the power line. Sealing screws: used to seal the casing of the electric energy meter to prevent unauthorized interference. The electric energy meter calculates the amount of electric energy used by monitoring the changes in current and voltage. When current passes through the electric energy meter, a magnetic field is generated. According to Faraday's law of electromagnetic induction, this magnetic field causes a current to be generated. By measuring the magnitude and duration of this current, the electric energy meter can accurately calculate the amount of electric energy used.

[0028] In addition, please refer to Figure 1 and Figure 2 A detachable cover plate 2 is also installed on the shell 1, and a limiting plate 201 is fixedly connected to the inner wall of the cover plate 2. A limiting groove 101 is provided on the shell 1, and the limiting plate 201 is snap-fitted and connected to the limiting groove 101, thereby ensuring the limiting effect of the cover plate 2, so that it can be limited by the limiting groove 101 on the shell 1 to prevent shaking when the cover plate 2 is installed, and the limiting plate 201 can also move along the limiting groove 101, so that it can guide the cover plate 2 to move conveniently and quickly, and a lead sealing screw 6 is also provided on the cover plate 2, and the lead sealing screw 6 extends into the shell 1 to seal the cover plate 2, and a contact plate 202 is fixedly connected to the outer wall of the cover plate 2. By providing the contact plate 202, the worker's hand can be better in contact with the cover plate 2, and the speed of disassembly can be increased when the cover plate 2 is disassembled.

[0029] Here, a placement hole 5 is also opened on the cover plate 2, and a magnetic block 501 is also arranged in the placement hole 5. When the lead sealing screw 6 on the cover plate 2 needs to be removed, the lead sealing screw 6 can be placed in the placement hole 5 for convenient storage. At the same time, the magnetic block 501 will also magnetically cooperate with the end of the lead sealing screw 6, so that it can magnetically limit the lead sealing screw 6. Then, when the cover plate 2 is removed, the lead sealing screw 6 can be placed in the placement hole 5 for storage, reducing the number of times the lead sealing screw 6 is lost.

[0030] Reference Figure 3 and Figure 4A telescopic rope 3 is also fixedly connected to the cover plate 2, and a locking column 4 is fixedly connected to the end of the telescopic rope 3, and two groups of symmetrical extension blocks 401 are also fixedly connected to the locking column 4, and a locking hole 102 is also opened on the outer wall of the shell 1, and the front end cross-section of the locking hole 102 is the same as the cross-section of the locking column 4, and the rear end cross-section of the locking hole 102 is circular, and the diameter of the circle is larger than the length of the distance between the end of the left extension block 401 to the end of the right extension block 401, so that the locking column 4 can be inserted into the locking hole 102, and the position of the extension block 401 can be rotated to adjust.

[0031] Here, when the cover plate 2 needs to be disassembled, the locking column 4 can be inserted into the hole along the front end of the locking hole 102, and then the locking column 4 can be rotated 90° to make the extension block 401 and the locking hole 102 intertwined with each other, thereby limiting the locking column 4. When the locking column 4 needs to be taken out, the locking column 4 can be rotated in the opposite direction to make the extension block 401 coincide with the front end of the locking hole 102, and then the locking column 4 can be disassembled, thereby reducing the number of times the cover plate 2 is lost, effectively storing and limiting the cover plate 2, and preventing unnecessary losses.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
