Description

Technical Field

[0001] This utility model relates to the technical field of fixing devices for electricity meters, and in particular to a fixing device for electricity meters based on a magnetic lock structure. Background Technology

[0002] As an indispensable metering device in the power system, the development of electricity meters is closely linked to the progress of the power industry. Early mechanical induction electricity meters measured electricity through the rotation of an aluminum disc, which had low accuracy and limited functionality. With breakthroughs in electronic technology, electronic electricity meters adopted high-precision sampling and digital processing technologies, improving metering accuracy and realizing advanced metering functions such as multi-rate and maximum demand. In the era of smart grids, smart electricity meters integrated intelligent functions such as two-way communication, remote fee control, and event recording. They are connected to the electricity information collection system through communication methods such as carrier waves, low-power wireless, or fiber optics, becoming an important infrastructure supporting smart electricity consumption, distributed energy access, and demand-side management. Currently, the new generation of electricity meters is developing towards high precision, multi-parameter measurement, edge computing, and Internet of Things, playing a key role in emerging fields such as electricity market trading, carbon metering, and virtual power plants. Their data value has transcended the traditional metering scope, becoming an important data node in building a new type of power system.

[0003] Electricity meters are directly connected to household or industrial circuits. Fixtures ensure a tight fit between the meter and the wall or distribution box, preventing loosening and reducing the risk of electric shock. In current applications, different sizes of electricity meters are used in different scenarios. If the fixture only supports a single size, multiple fixtures will need to be customized for different sizes, increasing procurement costs. Existing fixtures may also be unusable, leading to material waste. Mismatches between the meter and fixture size can cause poor contact through forced installation (e.g., using shims or misaligned screws), resulting in localized overheating or even fires. The meter may also slip off the fixture, injuring people or damaging equipment. Furthermore, if the fixture cannot be quickly installed or removed in case of malfunction, maintenance efficiency will be significantly reduced, increasing safety risks. Forced removal can cause irreversible damage to the casing or internal structure, reducing the equipment's impact resistance and increasing the risk of subsequent malfunctions. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1: Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an energy meter fixing device based on a magnetic lock structure, including a support frame 1, a protective shell 2 installed on one side of the support frame 1, mounting brackets 3 fixedly connected to both sides of the protective shell 2, mounting components 4 provided on the outer side of the mounting brackets 3, mounting blocks 5 fixedly connected to the inner wall of the support frame 1, an adaptation component 6 provided on the outer side of the mounting blocks 5, a support plate 7 installed on the outer side of the adaptation component 6, and an energy meter body 8 installed on the top of the support plate 7.

[0025] The support frame 1 serves as the basic framework of the entire electricity meter fixing device, providing installation support and structural stability for other components. The protective shell 2 protects the electricity meter body 8 from damage caused by external dust, moisture, collisions, and other factors, extending the electricity meter's service life. It also has an aesthetic function. The open frame on the inner wall of the protective shell 2 is used to install glass or other transparent materials, allowing for observation of the electricity meter body 8's display value even when the protective shell 2 is closed. The mounting bracket 3 provides an installation position for the mounting components 4 and also assists the protective shell. 2 is connected and fixed to the support frame 1 to enhance the stability of the overall structure. The installation component 4 allows for quick disassembly and installation of the protective shell 2 when needed, thus facilitating the maintenance of the electricity meter body 8. The installation block 5 provides a fulcrum for the installation of the adaptation component 6. The adaptation component 6 can easily accommodate electricity meter bodies 8 of different sizes, thereby improving the applicability of the device. The support plate 7 provides a fulcrum for the installation of the electricity meter body 8. The electricity meter body 8 is the object fixed by the entire fixing device. Stable installation is achieved through this device, facilitating electricity metering and other work.

[0026] The mounting component 4 includes a limiting rod 41 that is slidably connected to the inner wall of the support frame 1, a magnet 42 that is fixedly connected to one side of the mounting bracket 3, a limiting block 43 that is fixedly connected to one side of the mounting bracket 3, and the inner wall of the limiting block 43 is inserted into the outer side of the limiting rod 41.

[0027] The limiting rod 41, through its insertion and engagement with the limiting block 43, limits and fixes the mounting frame 3, thereby securely installing the protective shell 2 onto the support frame 1. It should be noted that the material of the limiting rod 41 needs to be magnetically attracted to prevent the magnet 42 from losing its effect and causing instability in the installation of the protective shell 2. When it is necessary to disassemble or install the protective shell 2, the connection state between the limiting rod 41 and the limiting block 43 can be controlled by sliding the limiting rod 41. The magnet 42 can use its magnetic attraction to pull the limiting rod 41 into the limiting block 43, enhancing the stability and convenience of installation, while also preventing the protective shell 2 from loosening to a certain extent. The inner wall of the limiting block 43 has multiple holes, which, through their engagement with the limiting rod 41, can adjust the horizontal position of the mounting frame 3 and the protective shell 2, thereby facilitating the adjustment of the cavity size between the support frame 1 and the inner wall of the protective shell 2, and thus adapting to different sizes of electricity meters.

[0028] The adaptation component 6 includes a support rod 61 rotatably connected to the outside of the mounting block 5, a fixing rod 62 fixedly connected to the bottom of the support plate 7, a connecting ring 63 slidably connected to the outside of the fixing rod 62, and the inner wall of the connecting ring 63 rotatably connected to one end of the support rod 61. A spring 64 is provided on the outside of the fixing rod 62.

[0029] The support rod 61 can be rotatably connected to the connecting ring 63, allowing for flexible angle adjustment when the support plate 7 is subjected to different directions or forces. When different sizes of electricity meters are installed, the position and stress of the support plate 7 will change. The support rod 61 can adapt to this change by rotating, providing a suitable support height for the support plate 7. The fixed rod 62 provides a sliding track for the connecting ring 63, allowing the connecting ring 63 to slide on its outer side. Different sizes of electricity meters may have different weights. The sliding of the connecting ring 63 on the fixed rod 62 can adjust the support point position. Together with the spring 64, the support plate 7 can effectively and elastically support electricity meters of different sizes. The connecting ring 63 can transfer the supporting force of the support rod 61 to the fixed rod 62. At the same time, its sliding characteristics can compress the spring 64 to further increase the supporting force of the support plate 7, thus facilitating flexible adjustment according to electricity meters of different weights and sizes.

[0030] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the inner wall of the support frame 1 is threaded with a connecting rod 9, and one end of the connecting rod 9 is rotatably connected to a limit bracket 10 for limiting the power meter.

[0032] Rotating the connecting rod 9 can move the limiting frame 10, thereby limiting the top of the electricity meter body 8. This, in conjunction with the adapting component 6, adjusts the limiting strength of the device on the electricity meter body 8. The limiting frame 10 can move under the drive of the connecting rod 9 to limit the electricity meter body 8, preventing displacement of the electricity meter body 8 on the support plate 7. In conjunction with the adapting component 6, it ensures the accuracy of the position of electricity meters of different sizes after installation.

[0033] Specifically, a limiting ring 11 is fixedly connected to the outer side of the connecting rod 9, and the outer side of the limiting ring 11 is rotatably connected to the outer side of the limiting frame 10. A protective tube 12 for protecting the outer threads of the connecting rod 9 is fixedly connected to the top of the support frame 1.

[0034] The limiting ring 11 can prevent the connecting rod 9 from disengaging from the limiting frame 10 when it rotates. At the same time, the rotation connection can also prevent the connecting rod 9 from driving the limiting frame 10 to rotate. The protective tube 12 can be used to protect the threads on the outside of the connecting rod 9 to prevent the threads from getting stuck due to dust or foreign objects, thus ensuring the normal rotation and service life of the connecting rod 9.

[0035] Specifically, a limiting piece 13 is fixedly connected to the outer side of the connecting rod 9, and a positioning rod 14 is fixedly connected to the inner wall of the support frame 1, with the outer side of the positioning rod 14 slidably connected to the inner wall of the limiting frame 10.

[0036] The setting of the limiting piece 13 can further limit the range of vertical movement of the connecting rod 9, prevent the connecting rod 9 from rotating excessively, and ensure that the limiting frame 10 can stably limit the energy meter body 8, thus ensuring the limiting effect. The setting of the positioning rod 14 can provide guidance and limiting for the movement of the limiting frame 10, so that the limiting frame 10 can move stably along the direction of the positioning rod 14, ensuring the accuracy of the limiting frame 10 in limiting the energy meter.

[0037] Specifically, a mounting rod 15 is fixedly connected to one side of the protective shell 2, and a positioning plate 16 for limiting the position of the electricity meter body 8 is fixedly connected to one end of the mounting rod 15.

[0038] The mounting rod 15 is used to fix the positioning plate 16 in a suitable position so as to limit the position of the electricity meter body 8. The positioning plate 16 can be adjusted when the protective shell 2 is adjusted, thereby realizing the limitation of electricity meters of different sizes. At the same time, it can extend the limitation range of the protective shell 2, ensuring the stability of the position of the electricity meter body 8 on the fixing device and adapting to the installation and fixing requirements of electricity meters of different sizes.

[0039] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, a support frame 17 is fixedly connected to the top of the support frame 1, a support block 18 is rotatably connected to the top of the support frame 17, and one end of the support block 18 is rotatably connected to the bottom of the support plate 7.

[0041] The support frame 17 provides installation support for the support block 18, enabling the support block 18 to be stably installed above the support frame 1, thereby enhancing the overall stability of the support plate 7. The support block 18 plays an auxiliary support role, enhancing the stability of the support plate 7. At the same time, its rotation characteristics can adapt to the position changes of the support plate 7 under different conditions, and it can also prevent the support plate 7 from tilting. Together with the adaptation component 6, it can better adapt to different sizes of electricity meters.

[0042] Specifically, a toggle lever 19 is fixedly connected to the outer side of the limiting rod 41, and a positioning piece 20 is fixedly connected to one end of the limiting rod 41.

[0043] The lever 19 allows the operator to manually move the limiting lever 41, enabling the limiting lever 41 to slide on the inner wall of the support frame 1. This allows for the insertion or separation of the limiting lever 41 and the limiting block 43, facilitating the installation and disassembly of the protective shell 2. The positioning piece 20 limits the sliding range of the limiting lever 41, preventing it from sliding out of the inner wall of the support frame 1, ensuring the normal use of the installation component 4, and guaranteeing the stability of the connection between the protective shell 2 and the support frame 1.

[0044] In use, first rotate the connecting rod 9. The connecting rod 9 drives the limiting frame 10 to move vertically, thereby increasing the installation space within the support frame 1 and preventing the limiting frame 10 from obstructing the installation process. Then, place the energy meter body 8 above the support plate 7. Then rotate the connecting rod 9 again. The connecting rod 9 drives the limiting frame 10 to press the energy meter body 8. At this time, the energy meter body 8 moves down to press the support plate 7. At the same time, the opening and closing angle of the two sets of support rods 61 increases, causing the connecting ring 63 to press the spring 64 and lift the support plate. 7. This, in conjunction with the downward pressure of the limit bracket 10, completes the limiting of the energy meter body 8. At this time, you can hold the handles on both sides of the protective shell 2 and slide the protective shell 2 to the outside of the support frame 1. At the same time, it drives the mounting bracket 3, magnet 42, and limit block 43 to move horizontally. At this time, first gently press the toggle rod 19 to prevent the limit rod 41 from being inserted into the wrong hole of the limit block 43. After reaching the appropriate position, the magnetic force of the magnet 42 pulls the limit rod 41 to insert into the limit block 43, thereby completing the fixation of the energy meter body 8.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
