[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: A metering box installation structure that is easy to install and dismantle, see [link / reference] Figures 1 to 6The assembly includes: a housing 2, with a fixing plate 1 at the rear end and a door 22 at the front opening; an installation structure located between the housing 2 and the fixing plate 1 to enable quick assembly and disassembly of the housing 2, the installation structure including: a guide rail 12, which is inverted T-shaped and fixedly connected to the side of the fixing plate 1 near the housing 2, with a connecting frame 21 slidably fitted on the outer side of the guide rail 12 and fixedly connected to the top of the housing 2; two support plates 13, which are respectively located on both sides of the bottom of the housing 2, and one end of each support plate 13 is fixedly connected to the fixing plate 1; and a limiting component located between the bottom of the housing 2 and the support plates 13 to position the installed housing 2 and improve installation stability.

[0031] This device, through its designed installation structure and limiting components, achieves the following during use:

[0032] Tool-free quick installation and disassembly: The longitudinal insertion and removal of the box 2 is achieved by sliding the inverted T-shaped guide rail 12 with the connecting frame 21 (gap ≤ 0.5mm). The initial positioning of the box 2 and the fixing plate 1 can be completed quickly. Compared with the traditional multi-bolt fixing, the installation efficiency of the box 2 is greatly improved. It is especially suitable for high-altitude operations or construction in confined spaces, and significantly reduces the difficulty of manual operation.

[0033] Three-dimensional stable support structure: The two support plates 13 at the bottom of the box 2 and the top guide rail 12 form a "three-point" rigid support. The horizontal installation of the support plates 13 ensures that the box 2 does not tilt when bearing weight. With the locking effect of the limiting component, the box 2 is stably limited on the support plates 13, which improves the stability of the box 2 installation.

[0034] For details, see Figure 2 — Figure 4The limiting component includes first insertion holes 41 on two support plates 13 and two second insertion holes 42 on the bottom of the inner cavity of the housing 2. The two first insertion holes 41 correspond to the two second insertion holes 42 in position and are sized to fit each other. Circular grooves 43 are provided on both sides of the housing 2 of the second insertion holes 42. A first spring 44 is fixedly connected to the bottom of the inner cavity of the circular groove 43. A T-shaped insert plate 4 is slidably inserted into the second insertion hole 42. The top of the first spring 44 is fixedly connected to the insert plate 4. The outer dimensions of the insert plate 4 are consistent with those of the second insertion holes 42. The internal dimensions of the hole 42 are compatible, and the head size of the insert plate 4 is larger than the size of the second insertion hole 42. Under the tension of the first spring 44, when the second insertion hole 42 corresponds to the first insertion hole 41, the insert plate 4 automatically inserts into the first insertion hole 41 of the support plate 13, forming a mechanical locking state. No manual alignment or auxiliary tools are required, avoiding the need for repeated alignment when using bolt connections, which reduces installation efficiency. When disassembling, simply pull the insert plate 4 upward to disengage it from the first insertion hole 41, and it can be pulled out axially along the guide rail 12, making disassembly more convenient.

[0035] Further, see Figure 4 and Figure 5 The top outer side of the insert plate 4 is slidably fitted with an inverted U-shaped positioning plate 6. The bottom sides of the box 2 of the positioning plate 6 are provided with inverted T-shaped grooves 61. Inverted T-shaped sliders 62 are slidably connected in both grooves 61, and both sliders 62 are fixedly connected to the positioning plate 6. A second spring 63 is fixedly connected between one end of the inner cavity of the groove 61 and the slider 62. Under the tension of the second spring 63, the inverted U-shaped positioning plate 6 covers the top of the insert plate 4. Thus, the box 2 can be prevented from falling off due to accidental contact by first sliding the inverted U-shaped positioning plate 6 away from the insert plate 4. Furthermore, the positioning plate 6 of the inverted U-shaped frame is set inside the box 2, and non-professionals cannot disassemble the box 2, thereby effectively improving the anti-theft performance of the box 2.

[0036] It is worth noting that, see Figure 6 The slider 62 is provided with baffles 64 on both sides of the end near the second spring 63. The bottom of the two baffles 64 is fixedly connected to the bottom of the inner cavity of the inverted T-shaped groove 61. The distance between the two baffles 64 is less than the width of the slider 62. The baffles 64 are less than the width of the slider 62 to form a lateral stop, which strictly limits the sliding stroke of the slider 62 within the effective range of the inverted T-shaped groove 61. This prevents the second spring 63 from being pulled too far, causing the positioning plate 6 to detach from the insert plate 4 and affecting the limiting effect of the insert plate 4.

[0037] It is worth noting that, see Figure 6The slider 62 is integrally formed from magnetic material. A permanent magnet 7 is embedded at the end of the inner cavity of the groove 61 away from the second spring 63. When the positioning plate 6 slides away from the insert plate 4, the slider 62 comes into contact with the permanent magnet 7, and the permanent magnet 7 attracts the slider 62. Since the attraction force of the permanent magnet 7 on the slider 62 is greater than the pulling force of the second spring 63, the positioning plate 6 is limited when the box 2 is installed or removed, so as to prevent the movement of the positioning plate 6 from affecting the pull strap of the insert plate 4, making the installation and removal of the box 2 more convenient. When it is necessary for the positioning plate 6 to limit the insert plate 4, the slider 62 can be disengaged from the permanent magnet 7 by manually moving the positioning plate 6.

[0038] It is worth mentioning that, see Figure 3 A rubber sealing gasket 5 is fixedly connected to the surface of the support plate 13. The rubber sealing gasket 5 is elastic. The compression deformation of the elastic rubber gasket (Shore hardness 60A) fills the tiny gap between the box 2 and the support plate 13, preventing rainwater and dust from entering the box 2 through the first socket 41 and the second socket 42. The elastic properties of the rubber gasket absorb mechanical vibrations (such as electromagnetic vibrations of transformers) during equipment operation, and attenuate the energy transmitted to the box 2, reducing the loosening or poor contact of internal wiring terminals caused by vibration.

[0039] It is worth mentioning that, see Figure 2 A wire hole 3 is provided at the bottom center of the box 2. An elastic rubber ring 31 is fixedly connected to the inner wall of the wire hole 3. The setting of the elastic rubber ring 31 increases the sealing between the cable in the wire hole 3 and the wire hole 3, thereby improving the sealing performance.

[0040] It is worth mentioning that, see Figure 1 The fixing plate 1 has mounting holes 11 at each of its four corners. The mounting holes 11 are used for expansion bolts to pass through, so as to fix the fixing plate 1 to the wall. By adapting the expansion bolts to the mounting holes 11 at the four corners of the fixing plate 1, it can be firmly installed on various base surfaces such as concrete, brick walls, and steel structures, meeting the installation needs of all scenarios such as outdoor columns and wall hanging.

[0041] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0042] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
