Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an electric meter box. Background Technology

[0002] Electricity meter boxes are protective devices for electricity meters. They are required in public facilities such as municipalities, residential communities, telecommunications companies, power companies, rural power grids, factories, enterprises, government agencies, heating companies, and fire stations. Traditional electricity meter boxes consist of a box body and a cover. Currently, most meter boxes are installed outdoors. Due to prolonged exposure to wind and sun, dust accumulates on the glass or plastic viewing windows, causing inconvenience for users and electricians when checking the meter.

[0003] The existing Chinese patent application number CN201420410141.6, entitled "An Electricity Meter Box," discloses "an electricity meter box, comprising a box body, the box body being composed of an upper box body and a lower box body, the upper box body and the lower box body being screwed together; the upper box body is provided with a viewing window, characterized in that a slide rail is provided on the wall where the viewing window is fastened to the upper box body, and a dust removal device is slidably connected to the slide rail; it also includes a fan, the fan being installed in a mounting groove formed by the combination of an upper mounting groove provided on the side of the upper box body and a lower mounting groove provided on the side of the lower box body, the fan being rotatably connected to a motor provided inside the box body." While it uses a dust removal device for dust removal, the inside of the viewing window cannot be wiped, causing some inconvenience for users viewing the meter or for electricians checking the meter. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an electric meter box that solves the problem of dust accumulating in the viewing window in the prior art, making it inconvenient for users to view or for electricians to check the meter.

[0005] To address the above problems, the following technical solution is provided: An electric meter box includes a box body with an observation opening. A viewing window is installed inside the observation opening. A dust removal device is installed at the observation opening. The viewing window includes a cover plate, a transparent plate, and a bottom plate arranged sequentially from the outside to the inside. Both the cover plate and the bottom plate have through-holes corresponding to the transparent plate. The dust removal device includes a movable plate, a first wiping block, a linkage plate, and a second wiping block. Slide rails are provided on the inner walls of the upper and lower sides of the observation opening. The top of the movable plate and the linkage plate are provided with movable heads that cooperate with the slide rails, and the bottom of the movable plate is provided with fixed heads that cooperate with the slide rails. Corresponding magnets are embedded on opposite sides of the movable plate and the linkage plate and clamped on both sides of the viewing window to achieve corresponding adsorption. The first wiping block is installed on the side of the movable plate facing the viewing window and is located inside the through-hole, abutting against the transparent plate. The second wiping block is installed on the side of the linkage plate facing the viewing window and is located inside the through-hole, abutting against the other side of the transparent plate.

[0006] In the above structure, when an electrician needs to check the meter, the movable plate can be controlled to move the linkage plate, the first wiping block, and the second wiping block back and forth towards the other end to clean the dust or water stains on the transparent plate, thus facilitating meter reading and improving the ease of use of this invention. The magnet allows the movable plate and the linkage plate to be attracted to each other, enabling the movable plate to control the movement of the linkage plate. This allows the second wiping block to wipe the inside of the transparent plate, preventing water vapor from affecting meter reading and improving the reliability of this invention. The through-hole allows the electrician to easily check the meter through the transparent plate, further enhancing the convenience of this invention. The cooperation of the movable head, fixed head, and slide rail improves the stability of the displacement of the movable plate and the linkage plate, thereby improving the reliability of the dust removal device.

[0007] The present invention is further configured such that the top of the movable plate and the linkage plate are provided with mounting holes, the mounting holes are provided with clearance holes in the radial direction, the outer surfaces of the movable plate and the linkage plate are provided with clearance grooves corresponding to the mounting holes, the movable head is provided with a push block in the radial direction, and a spring is provided in the mounting hole to abut against the bottom end of the movable head.

[0008] In the above structure, the provision of a clearance hole and a clearance groove facilitates the installation of the movable head. After the push block enters the clearance hole, the movable head rotates, causing the push block to move into the clearance groove. This allows the user or electrician to easily move the movable head using the push block, facilitating the assembly and disassembly of the dust removal device. The bottom of the clearance hole is located in the middle of the clearance groove. Therefore, during the installation of the movable head, the spring force pushes it to the upper end of the clearance groove, preventing the push block from aligning with the bottom of the clearance hole, thus providing a limiting effect and improving the reliability of this invention. The spring ensures the movable head is positioned within the slide rail, improving the stability of the displacement of the movable plate and the linkage plate, and facilitating the assembly and disassembly of the movable head.

[0009] The present invention is further configured such that the bottom end of the mounting hole and the bottom end of the movable head are both provided with positioning holes with a diameter smaller than that of the mounting hole for accommodating the two ends of the spring.

[0010] In the above structure, the positioning hole facilitates the positioning and installation of the spring and improves the stability of the spring, thereby enhancing the reliability of this utility model.

[0011] The present invention is further configured such that the first wiping block is fixed to the inside of the movable plate by Velcro.

[0012] The above structure facilitates the disassembly and replacement of the first wiping block, thereby improving the convenience and reliability of this utility model.

[0013] The present invention is further configured such that a rubber scraper is provided on the side of the first wiping block facing its displacement direction, and the side of the rubber scraper that abuts against the transparent plate is toothed.

[0014] The above structure facilitates the removal of stubborn stains by the rubber scraper and makes it easier to clean the first wiping block, thus improving the reliability of this invention.

[0015] The present invention is further provided with an easy-push plate on the outer side of the movable plate.

[0016] The above structure makes it easy for users or electricians to push the movable plate with the push plate, thus improving the ease of operation of this utility model. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] like Figures 1 to 8 An electric meter box is shown, including a box body 1. An observation port 11 is provided on the box body 1, and a viewing window 2 is installed inside the observation port 11. A dust removal device 3 is installed at the observation port 11. The viewing window 2 includes a cover plate 21, a transparent plate 22, and a bottom plate 23 arranged sequentially from the outside to the inside. Both the cover plate 21 and the bottom plate 23 have through openings 01 corresponding to the transparent plate 22. The dust removal device 3 includes a movable plate 31, a first wiping block 32, a linkage plate 33, and a second wiping block 34. Slide rails 12 are provided on the inner walls of the upper and lower sides of the observation port 11. Both the top of the plate 31 and the linkage plate 33 are provided with movable heads 4 that cooperate with the slide rail 12, and the bottom of the plate is provided with fixed heads 5 that cooperate with the slide rail 12. Corresponding magnets 6 are embedded on the opposite side of the movable plate 31 and the linkage plate 33, and are clamped on both sides of the viewing window 2 to achieve corresponding adsorption. The first wiping block 32 is installed on the side of the movable plate 31 facing the viewing window 2 and is located in the through opening 01 and abuts against the transparent plate 22. The second wiping block 34 is installed on the side of the linkage plate 33 facing the viewing window 2 and is located in the through opening 01 and abuts against the other side of the transparent plate 22.

[0029] In the above structure, when an electrician needs to check the meter, the movable plate 31 can be controlled to move the linkage plate 33, the first wiping block 32, and the second wiping block 34 back and forth towards the other end to clean the dust or water stains on the transparent plate 22, thus facilitating meter checking and improving the convenience of this invention. The magnet 6 allows the movable plate 31 and the linkage plate 33 to be attracted to each other, enabling the movable plate 31 to control the movement of the linkage plate 33. This allows the second wiping block 34 to wipe the inside of the transparent plate 22, preventing water vapor from affecting meter checking and improving the reliability of this invention. The through-hole 01 facilitates meter checking through the transparent plate 22, further improving the convenience of this invention. The movable head 4, the fixed head 5, and the slide rail 12 work together to improve the stability of the displacement of the movable plate 31 and the linkage plate 33, thereby improving the reliability of the dust removal device 3.

[0030] In this embodiment, the top of both the movable plate 31 and the linkage plate 33 are provided with mounting holes 02, and the mounting holes 02 are provided with relief holes 03 in the radial direction. The outer surfaces of both the movable plate 31 and the linkage plate 33 are provided with relief grooves 04 corresponding to the mounting holes 02. The movable head 4 is provided with a push block 41 in the radial direction. A spring 7 is provided in the mounting hole 02 to abut against the bottom of the movable head 4.

[0031] In the above structure, by providing the clearance hole 03 and the clearance groove 04, it is convenient for the movable head 4 to be installed. After the push block 41 enters the clearance hole 03, the movable head 4 is rotated, causing the push block 41 to rotate into the clearance groove 04. This allows the user or electrician to push the movable head 4 to move using the push block 41, facilitating the assembly and disassembly of the dust removal device 3. The bottom end of the clearance hole 03 is located in the middle of the clearance groove 04. Therefore, when installing the movable head 4, it can be pushed to the upper end of the clearance groove 04 by the elastic force of the spring 7, preventing the push block 41 from corresponding to the bottom end of the clearance hole 03, thus playing a limiting role and improving the reliability of this utility model. By providing the spring 7, the movable head 4 can be located within the slide rail 12, thereby improving the stability of the displacement of the movable plate 31 and the linkage plate 33, and facilitating the assembly and disassembly of the movable head 4.

[0032] In this embodiment, both the bottom end of the mounting hole 02 and the bottom end of the movable head 4 are provided with positioning holes 021 with a diameter smaller than that of the mounting hole 02, which are used to accommodate the two ends of the spring 7.

[0033] In the above structure, the positioning hole 021 facilitates the positioning and installation of the spring 7 and improves the stability of the spring 7, thereby improving the reliability of this utility model.

[0034] In this embodiment, the first wiping block 32 is fixed to the inside of the movable plate 31 by Velcro 8.

[0035] The above structure facilitates the disassembly and replacement of the first wiping block 32, thereby improving the convenience and reliability of this utility model.

[0036] In this embodiment, the first wiping block 32 is provided with a rubber scraper 9 on one side facing its displacement direction, and the side of the rubber scraper 9 that abuts against the transparent plate 22 is toothed.

[0037] The above structure facilitates the removal of stubborn stains by the rubber scraper 9 and the cleaning of dust by the first wiping block 32, thus improving the reliability of this utility model.

[0038] In this embodiment, an easy-push plate 311 is provided on the outer side of the movable plate 31.

[0039] The above structure makes it easy for users or electricians to push the movable plate 31 through the push plate 311, thus improving the ease of operation of this utility model.

[0040] 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.
