Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and specifically relates to a sealing structure for a power metering box. Background Technology

[0002] As a key device for electricity metering and management, the background technology of electricity metering boxes originated from the need for miniaturization and standardization of electricity meters in the late 19th century. In the early days, mechanical electricity meters were the core, with limited functions and reliance on manual meter reading. In the mid-to-late 20th century, with the advancement of electronic technology, electronic electricity meters gradually replaced mechanical meters, significantly improving integration and accuracy. After the 21st century, smart grids have driven the transformation of metering boxes towards digitalization and intelligence, integrating communication modules and Internet of Things (IoT) technology to achieve remote meter reading, real-time monitoring, and two-way interaction. The development process has gone through iterations from mechanical metering to electronic metering, and then to smart terminals. Modern metering boxes have functions such as data storage, anti-theft, and load management. Their application scenarios cover residential communities, industrial and commercial power distribution, new energy power generation, public facilities, and other fields, becoming a core component of smart distribution networks and the energy internet, supporting refined electricity management and demand-side response.

[0003] Traditional power metering boxes often use simple rubber gaskets or bolt tightening for sealing, which results in insufficient sealing performance and aging and cracking after long-term use. Especially in humid, dusty, or temperature-varying environments, the box can easily become damp, accumulate dust, or even short-circuit, affecting metering accuracy and equipment lifespan. At the same time, the existing sealing structure is relatively rigid in fixing cables and lacks buffering and adjustment capabilities. During installation or maintenance, excessive compression can easily damage the cables, and it is difficult to adapt to the sealing requirements of different cable specifications.

[0004] The purpose of this utility model is to provide a sealing structure for an electricity metering box, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sealing structure for an electricity metering box, comprising, The bottom shell, the connecting bolts threaded to the side wall of the bottom shell, the sleeve sleeved on the surface of the connecting bolts, the snap-fit ​​assembly disposed on the inner wall of the sleeve sleeve, and the moving assembly disposed on the surface of the snap-fit ​​assembly.

[0006] As a preferred embodiment of this utility model, the snap-fit ​​assembly includes a snap-fit ​​housing fixedly connected to the inner wall of the housing, and a mounting groove disposed on the inner wall of the snap-fit ​​housing.

[0007] As a preferred embodiment of the present invention, the snap-fit ​​assembly further includes a connecting ring slidably connected to the inner wall of the mounting groove, and a top spring fixedly connected to the side wall of the connecting ring.

[0008] As a preferred embodiment of the present invention, the snap-fit ​​assembly further includes a mounting ring fixedly connected to the end of the top spring, and a washer sleeved on the surface of the mounting ring.

[0009] In a preferred embodiment of this utility model, the movable component includes a fixed ring fixedly connected to the inner wall of the housing, and rollers tumblingly connected to the inner wall of the fixed ring.

[0015] 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.

[0016] 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.

[0017] 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. Example

[0018] Reference Figures 1-4 This is an embodiment of the present invention, which provides a sealing structure for an electricity metering box, comprising: The bottom shell 101, the connecting bolt 102 threaded to the side wall of the bottom shell 101, the sleeve 103 sleeved on the surface of the connecting bolt 102, the snap-fit ​​assembly 104 disposed on the inner wall of the sleeve 103, and the moving assembly 105 disposed on the surface of the snap-fit ​​assembly 104.

[0019] Specifically, the snap-fit ​​assembly 104 includes a snap-fit ​​housing 104a fixedly connected to the inner wall of the housing 103, and a mounting groove 104b provided on the inner wall of the snap-fit ​​housing 104a. The snap-fit ​​assembly 104 also includes a connecting ring 104c slidably connected to the inner wall of the mounting groove 104b, and a top spring 104d fixedly connected to the side wall of the connecting ring 104c. The snap-fit ​​assembly 104 also includes a mounting ring 104e fixedly connected to the end of the top spring 104d, and a washer 104f sleeved on the surface of the mounting ring 104e.

[0020] Furthermore, the use of mounting ring 104e in conjunction with top spring 104d ensures that the device can move within a local area, allowing for appropriate position adjustments after wiring installation.

[0021] Preferably, the movable component 105 includes a fixed ring 105a fixedly connected to the inner wall of the housing 103, and a roller 105b rolledly connected to the inner wall of the fixed ring 105a. The movable component 105 also includes an inner ring 105c rolledly connected to the surface of the roller 105b, and a connecting groove 105d disposed on the surface of the inner ring 105c. The movable component 105 also includes a slot 105e disposed on the inner wall of the inner ring 105c, and a collar 105f fixedly connected to the side wall of the inner ring 105c.

[0022] It should be noted that the collar 105f is designed to facilitate the fixing of the line and ensure the stability of the line connection, while the connecting groove 105d is designed to assist in fixing the line.

[0023] In use, the wire is inserted through the collar 105f and initially positioned through the connecting groove 105d of the inner ring 105c. At this time, the roller 105b can roll within the fixing ring 105a, allowing the wire to be flexibly adjusted along the axial direction. The wire continues to pass through the through hole in the center of the mounting ring 104e, causing the connecting ring 104c to slide within the mounting groove 104b of the retainer 104a, forming an elastic buffer. The washer 104f prevents the wire from directly rubbing against the mounting ring 104e. When the wire needs fine adjustment, the top spring 104d allows the mounting ring 104e to move the wire within a small range in the radial direction. The roller 105b, in conjunction with the rolling of the inner ring 105c, allows the wire to rotate along the axial direction. Finally, the retainer 103 and the base shell 101 are fixed by tightening the connecting bolt 102.

[0024] In summary, the combined use of the snap-fit ​​assembly 104 and the moving assembly 105 enables flexible adjustment and stable fixation of the line after installation. The combination of the top spring 104d and the mounting ring 104e provides the line with radial elastic buffering capability, effectively absorbing vibration and allowing for small-range displacement. The rolling engagement of the roller 105b and the inner ring 105c ensures free adjustment and rotation of the line axially, avoiding stress concentration caused by rigid connections. The engagement of the collar 105f and the connecting groove 105d enhances the positioning stability of the line. The washer 104f reduces frictional loss and extends service life. The tightening design of the connecting bolt 102 ensures the sealing of the overall structure, preventing external moisture or dust from entering. Thus, while ensuring the safe operation of the electrical components inside the power metering box, it also improves the convenience and reliability of line installation, making it suitable for long-term stable use under complex working conditions.
