Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology, and in particular relates to a closed structure for the card insertion port of an electricity meter. Background Technology

[0002] An electricity meter, commonly known as a power meter or kilowatt-hour meter, is an instrument used to measure electricity consumption and is the core basis for calculating electricity bills. Currently, there are various types of electricity meters, including mechanical induction meters, electronic meters, and smart meters. Electronic meters typically have a card slot on their casing, allowing an IC card to be inserted to read remaining electricity and transmit usage data. In existing technology, because the card slot on the electronic meter casing is connected to the internal circuit module, and most electronic meters lack a sealing structure inside the casing, the card slot cannot be sealed. This means that when no card is inserted, external moisture and liquids cannot be prevented from entering the meter through the card slot, easily causing moisture damage to the internal circuit module and affecting normal operation. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a closed structure for the card insertion port of an electricity meter, thereby solving the above-mentioned technical problems.

[0004] In view of this, the present invention provides a closed structure for a card insertion port of an electricity meter, comprising an electricity meter base, an electricity meter cover, and a circuit module. The circuit module is installed inside the electricity meter base and has a plug-in unit. The electricity meter cover is placed on the electricity meter base and has a card insertion hole, which is connected to the plug-in unit. The invention also includes a sealing assembly, which comprises:

[0005] A cover plate, which is rotatably connected to the inside of the upper cover of the electricity meter, is used to seal the card insertion hole;

[0006] A reset component is provided between the cover plate and the upper cover of the energy meter for rotating and resetting the cover plate;

[0007] An insert block, which is disposed on the cover plate, is used to insert and cooperate with the card slot;

[0008] The insert block has an abutting slope on the side away from the rotating connection, and the insert hole has a groove that is adapted to contact the abutting slope.

[0009] Furthermore, it also includes a sealing ring, which is disposed on the inside of the upper cover of the electricity meter to abut against the cover plate.

[0010] Furthermore, the sealing ring and the top cover of the electricity meter are fixed together by adhesive bonding.

[0011] Furthermore, the sealing ring is located at the card insertion hole.

[0012] Furthermore, it also includes:

[0013] Mounting bracket, wherein the mounting bracket is disposed on the inside of the upper cover of the electricity meter;

[0014] A rotating shaft, which is rotatably connected to a mounting base;

[0015] The cover plate is connected to the circumference of the rotating shaft, and the reset component is installed on one end of the rotating shaft with the mounting base and the cover plate connected to both ends respectively.

[0016] Furthermore, the reset element is a torsion spring.

[0017] The beneficial effects of this utility model are:

[0018] By installing a rotatable cover plate on the inside of the electricity meter's top cover, and using a torsion spring to control the rotation and reset of the cover plate, the cover plate can seal the card insertion hole when the electricity meter is not in use, preventing moisture and liquid from entering the electricity meter and affecting its use.

[0019] The cover plate is equipped with a plug with an abutting bevel, and the plug is inserted into the card slot by opening a groove on the card slot that matches the abutting bevel. This effectively prevents small external objects from entering the plug-in unit of the circuit module through the card slot, thus preventing the card insertion function of the energy meter from being affected. At the same time, the plug and the card slot do not jam during the rotation of the cover plate. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] Example 1:

[0029] This embodiment provides a closed structure for a card insertion port of an electricity meter, including an electricity meter base 1, an electricity meter cover 2, and a circuit module 3. The circuit module 3 is installed inside the electricity meter base 1 and has a plug-in unit 31. The electricity meter cover 2 covers the electricity meter base 1 and has a card insertion hole 21. The card insertion hole 21 is connected to the plug-in unit 31. The embodiment also includes a sealing assembly 4, which includes:

[0030] Cover plate 41, which is rotatably connected to the inside of the upper cover 2 of the energy meter, is used to seal the card insertion hole 21;

[0031] Reset component 42 is disposed between cover plate 41 and upper cover 2 of energy meter, and is used for rotating and resetting cover plate 41.

[0032] Insert block 43, which is disposed on cover plate 41 and is used to insert and cooperate with card insertion hole 21;

[0033] The insert block 43 has an abutting inclined surface 44 on the side away from the rotating connection, and the insert hole 21 has an inclined groove 22 that is adapted to contact the abutting inclined surface 44.

[0034] Furthermore, it also includes a mounting base 45 and a rotating shaft 46. The mounting base 45 is disposed inside the upper cover 2 of the energy meter, and the rotating shaft 46 is rotatably connected to the mounting base 45. The cover plate 41 and the rotating shaft 46 are circumferentially connected, and the reset member 42 is mounted on one end of the rotating shaft 46 and its two ends are respectively connected to the mounting base 45 and the cover plate 41. Furthermore, the reset member 42 is a torsion spring.

[0035] In this technical solution, the installation of the circuit module 3 inside the energy meter base 1 and the installation connection between the energy meter cover 2 and the energy meter base 1 are existing technologies and will not be described in detail. A mounting base 45 is provided inside the energy meter cover 2, and the mounting base 45 and the inner side of the energy meter cover 2 are integrally connected. A slot is provided on the mounting base 45. The cover plate 41 and the rotating shaft 46 are also integrally connected around their periphery, and a slot is also provided on the cover plate 41. The rotating shaft 46 is rotatably connected to the mounting base 45. A torsion spring is sleeved on one end of the rotating shaft 46, and both ends of the torsion spring are respectively engaged with the mounting base 45 and the cover plate 41 through the slots. The torsion spring is in a pre-compressed state, generating an elastic restoring force that causes the cover plate 41 to abut against the inside of the energy meter cover 2, thereby sealing the card insertion hole 21 of the energy meter cover 2 and preventing moisture and liquid from entering the energy meter.

[0036] An integrally formed insertion block 43 is provided on the cover plate 41, and an abutment slope 44 is formed on the side of the insertion block 43 away from the rotating shaft 46. Then, a groove 22 adapted to the abutment slope 44 is formed on the card insertion hole 21. With this structural design, when the cover plate 41 abuts against the upper cover 2 of the energy meter to block the card insertion hole 21, the insertion block 43 can be inserted into the card insertion hole 21, preventing small external debris from entering the insertion unit 31 of the circuit module 3 through the card insertion hole 21, and preventing the card insertion function of the energy meter from being affected.

[0037] By setting mutually compatible abutting inclined surfaces 44 and inclined grooves 22, it can be effectively ensured that the cover plate 41 tightly abuts against the upper cover 2 of the electricity meter. At the same time, when the IC card is inserted into the electricity meter through the card insertion hole 21 to push open the cover plate 41, the insertion block 43 and the card insertion hole 21 will not get stuck due to the rotation of the cover plate 41, which is highly practical.

[0038] Example 2:

[0039] This embodiment provides a closed structure for the card insertion port of an electricity meter, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] Furthermore, it also includes a sealing ring 47, which is disposed inside the upper cover 2 of the energy meter to abut against the cover plate 41. Furthermore, the sealing ring 47 and the upper cover 2 of the energy meter are fixed together by adhesive bonding.

[0041] In this technical solution, the sealing ring 47 is made of rubber and can be bonded to the outer ring of the card insertion hole 21 as shown in the figure. This allows the cover plate 41 to tightly adhere to the sealing ring 47 when sealing the card insertion hole 21, thereby enhancing the sealing performance of the cover plate 41 when sealing the card insertion hole 21. Furthermore, the sealing ring 47 is located at the card insertion hole 21. As shown in the figure, the sealing ring 47 can be positioned at the card insertion hole 21, and when the insert block 43 is inserted into the card insertion hole 21, it abuts against the sealing ring 47, thereby enhancing the sealing effect. Simultaneously, it reduces the space occupied by the sealing ring 47, lowering costs and increasing economic efficiency. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many other forms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
