Description

Technical Field

[0001] This utility model relates to the technical field of electricity meters, and in particular to an electricity meter casing. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy, also known as a kilowatt-hour meter, or watt-hour meter. It refers to instruments that measure various electrical quantities. Currently, electricity meters are increasingly widely used in industrial production and daily life due to their advantages such as small size, high accuracy, good reliability, and convenient installation. Existing electricity meters, in order to facilitate battery replacement, have a battery compartment on the front of the casing. The battery compartment and other components are covered by a flip cover. One end of the flip cover is hinged to the casing, and the other end is fixed to the casing by a locking device. Because there are gaps between the flip cover and the casing, rainwater can easily seep in and damage the components. Although a sealing ring can be added to seal it during use, the sealing ring is prone to loosening when the flip cover is opened and closed, resulting in poor sealing. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides an energy meter housing that is simple in structure, stable, and improves sealing performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outer casing of an electricity meter, comprising a casing body and a flip cover. A cavity is provided on the front side of the casing body. One end of the flip cover is hinged to the casing body and can be flipped to cover the cavity. A boss is provided within the cavity. An annular sealing groove is formed between the outer periphery of the boss and the cavity. A sealing element, adapted to the sealing groove, is provided on the inner side of the flip cover at a position corresponding to the sealing groove. The sealing element is inserted into the sealing groove to achieve a sealing seal between the flip cover and the casing body. The sealing element includes a mounting part and a sealing ring. The mounting part is fixed to the inner side of the flip cover, and the sealing ring is sleeved on the outer periphery of the mounting part. A fixing element for fixing the sealing ring is provided between the sealing ring and the mounting part.

[0005] By adopting the above technical solution, the protrusion inside the cavity is used to install components such as battery compartments and buttons in its position. The flip cover is used to cover the cavity and protect the components inside. The sealing groove and the sealing element are interlocked to ensure a seal when the flip cover is closed on the shell body, preventing rainwater from seeping in from the gaps around the flip cover and damaging the internal components. When the flip cover is opened, the sealing element located at the flip cover position disengages along the sealing groove as the flip cover rotates. The sealing ring is sleeved on the outside of the mounting part and fixed to the mounting part by the fixing element, making the sealing ring structure more stable. Even if the flip cover is opened and closed repeatedly, the sealing ring will not loosen with the opening and closing of the flip cover, thereby ensuring the sealing performance between the flip cover and the upper shell, improving the sealing effect, and further improving the reliability of the structure.

[0006] The present invention further comprises: the fixing member includes a connecting rod and an elastic plug; one end of the connecting rod is connected to the sealing ring facing the mounting part; the mounting part is provided with a through hole corresponding to the position of the connecting rod; the other end of the connecting rod passes through the through hole and is connected to the elastic plug; the outer diameter of the elastic plug is larger than the inner diameter of the through hole.

[0007] By adopting the above technical solution, when installing the sealing ring, the elastic plug on the inner side of the sealing ring is aligned with the through hole at the installation position. The elasticity of the elastic plug and the fact that its outer diameter is larger than the inner diameter of the through hole allow the elastic plug to be inserted along the through hole without easily dislodging from it, thus fixing the sealing ring and ensuring structural stability. Furthermore, when the sealing ring is damaged or the sealing effect decreases, the elastic plug can be pushed to disengage it along the through hole, thereby separating the sealing ring from the installation position, making disassembly and assembly convenient.

[0008] The present invention is further provided with the following configuration: four through holes are provided, each through hole is located at one of the four corners of the mounting part, and the number of fasteners matches the number of through holes.

[0009] By adopting the above technical solution, the through holes are set at the four corners of the mounting part, which plays a role in positioning and installing the sealing ring, facilitating the processing of the through holes, and making the fixing structure of the sealing ring installed by the fastener more stable, thereby further improving the reliability of the structure.

[0010] The present invention further comprises: the elastic plug is conical, and the tip of the elastic plug is positioned away from the connecting rod.

[0011] By adopting the above technical solution, the conical elastic plug is designed with a larger upper part and a smaller lower part, and its cone tip faces away from the connecting rod. When installing the sealing ring, the cone tip of the elastic plug is inserted first towards the through hole, which serves as a guide for installation, making the installation of the elastic plug more convenient and further improving the ease of installation.

[0012] The present invention is further provided in that: the protrusion is provided with a notch at the position corresponding to the elastic plug for accommodating the elastic plug when the flip cover is closed.

[0013] By adopting the above technical solution, the notch is designed so that when the flip cover is closed, the sealing element is inserted along the sealing groove direction, providing installation space for the elastic plug, making the structure more reasonable and compact.

[0014] The present invention is further provided that the sealing ring, connecting rod, and elastic plug are integrally formed.

[0015] By adopting the above technical solutions, the structural strength of the sealing ring is enhanced, the number of parts is reduced, and the installation steps are reduced, thereby further improving installation efficiency.

[0016] The present invention further provides that the distance from the mounting part to the bottom of the sealing groove is less than the distance from the sealing ring to the bottom of the sealing groove.

[0017] By adopting the above technical solution, when the flip cover is snapped shut, the mounting part is placed into the sealing groove before the sealing ring, which plays a positioning role in the installation of the sealing ring, making the insertion and sealing structure of the sealing groove and the sealing element more stable.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0025] See appendix Figure 1-5 This utility model discloses an electric energy meter casing, including a casing body 1 and a flip cover 2. The casing body 1 has a cavity 3 on its front side. One end of the flip cover 2 is hinged to the casing body 1 and can be flipped to cover the cavity 3. A boss 4 is provided in the cavity 3. An annular sealing groove 5 is formed between the outer periphery of the boss 4 and the cavity 3. A sealing element 6 adapted to the sealing groove 5 is provided on the inner side of the flip cover 2 and corresponding to the position of the sealing groove 5. The sealing element 6 is inserted into the sealing groove 5 to achieve the sealing of the flip cover 2 and the casing body 1. The sealing element 6 includes a mounting part 601 and a sealing ring 602. The mounting part 601 is fixed to the inner side of the flip cover 2. The sealing ring 602 is sleeved on the outer periphery of the mounting part 601. A fixing element 7 for fixing the sealing ring 602 is provided between the sealing ring 602 and the mounting part 601. The protrusion 4 inside the cavity 3 is used to install components such as the battery compartment and buttons. The flip cover 2 is used to cover the cavity 3 and protect the internal components. The sealing groove 5 and the sealing element 6 are interlocked to seal the flip cover 2 when it is closed on the shell body 1, preventing rainwater from seeping in from the gaps around the flip cover 2 and damaging the internal components. When the flip cover 2 is opened, the sealing element 6 located at the position of the flip cover 2 disengages along the sealing groove 5 as the flip cover 2 rotates. The sealing ring 602 is sleeved on the outside of the mounting part 601 and fixed to the mounting part 601 by the fixing element 7, making the sealing ring 602 structure more stable. Even if the flip cover 2 is opened and closed repeatedly, the sealing ring 602 will not loosen with the opening and closing of the flip cover 2, thereby ensuring the sealing performance between the flip cover 2 and the upper shell, improving the sealing effect, and further improving the reliability of the structure.

[0026] This embodiment further includes the following: the fixing member 7 includes a connecting rod 701 and an elastic plug 702. One end of the connecting rod 701 is connected to the sealing ring 602 on the side facing the mounting part 601. The mounting part 601 is provided with a through hole 8 corresponding to the position of the connecting rod 701. The other end of the connecting rod 701 passes through the through hole 8 and is connected to the elastic plug 702. The outer diameter of the elastic plug 702 is larger than the inner diameter of the through hole 8. When installing the sealing ring 602, align the elastic plug 702 on the inner side of the sealing ring 602 with the through hole 8 at the mounting part 601. The elasticity of the elastic plug 702 and the fact that its outer diameter is larger than the inner diameter of the through hole 8 allow the elastic plug 702 to be inserted along the through hole 8 without easily dislodging from it, thus fixing the sealing ring 602 and ensuring structural stability. Furthermore, when the sealing ring 602 is damaged or its sealing effect decreases, the elastic plug 702 can be pushed to disengage it along the through hole 8, thereby separating the sealing ring 602 from the mounting part 601, making disassembly and assembly convenient.

[0027] This embodiment further includes four through holes 8, each located at one of the four corners of the mounting portion 601. The number of fixing members 7 matches the number of through holes 8. The through holes 8, located at the four corners of the mounting portion 601, serve to position and install the sealing ring 602, facilitating the machining of the through holes 8. Simultaneously, this makes the fixing structure of the sealing ring 602, installed via the fixing members 7, more stable, further improving the reliability of the structure.

[0028] This embodiment further specifies that the elastic plug 702 is conical, with the tip of the plug facing away from the connecting rod 701. The conical shape of the elastic plug 702 results in a structure where the plug is larger at the top and smaller at the bottom, and its tip faces away from the connecting rod 701. When installing the sealing ring 602, the tip of the elastic plug 702 is inserted first towards the through hole 8, serving as a guide for installation and making the installation of the elastic plug 702 more convenient, further improving installation ease.

[0029] This embodiment further includes a notch 9 on the protrusion 4 corresponding to the position of the elastic plug 702, for accommodating the elastic plug 702 when the flip cover 2 is closed. The notch 9 provides installation space for the elastic plug 702 when the flip cover 2 is closed and the sealing member 6 is inserted along the sealing groove 5, making the structure more reasonable and compact.

[0030] In this embodiment, the sealing ring 602, connecting rod 701, and elastic plug 702 are integrally formed. This enhances the structural strength of the sealing ring 602, reduces the number of parts, and decreases installation steps, thereby further improving installation efficiency.

[0031] In this embodiment, the distance from the mounting part 601 to the bottom of the sealing groove 5 is less than the distance from the sealing ring 602 to the bottom of the sealing groove 5. When the flip cover 2 is fastened, the mounting part 601 is inserted into the sealing groove 5 before the sealing ring 602, which plays a positioning role in the installation of the sealing ring 602, making the insertion and sealing structure between the sealing groove 5 and the sealing element 6 more stable.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
