Technical Field
[0001] This application relates to the technical field of electricity metering boxes, and in particular to an easy-to-install electricity metering box. Background Technology
[0002] Electricity metering boxes, as indispensable key equipment in power systems, have the core function of accurately measuring and recording electricity consumption. This function plays a crucial role in electricity bill management, cost control, and promoting energy conservation. As an important tool for power management, electricity metering boxes play a pivotal role in ensuring stable power supply and promoting efficient energy use, thus possessing broad application prospects and significant value in power systems.
[0003] From a technical perspective, modern electricity metering boxes typically use aluminum alloy for the enclosure and are equipped with a door. The interior integrates various precision components, including combined current transformers, electricity meters, and vacuum circuit breakers. These components work together to ensure the accuracy and reliability of electricity metering. Furthermore, depending on the application scenario and specific needs, electricity metering boxes may also be equipped with auxiliary devices such as terminals, wires, and protective components to further enhance their functionality and performance.
[0004] However, despite significant advancements in the technology and application of electricity metering boxes, their use in outdoor sandy environments still faces several challenges. The tiny particles in sand are highly permeable and can penetrate the box through gaps in the casing and doors, causing seal failure. Once the seal fails, the delicate components inside the metering box are directly exposed to harsh environmental factors such as sand, moisture, and wind. This not only degrades component performance but may also trigger malfunctions, threatening the accuracy and reliability of electricity metering and indicating room for improvement.

One side of the door 2 is hinged to the vertical side wall of the mounting recess 12, and the other side of the door 2 is detachably connected to the enclosure 1 via a conventional locking structure. When the door 2 is locked, it rotates into the mounting recess 12, and the elastic sealing strip 21 on the door 2 abuts against the inner wall of the mounting recess 12, improving the corresponding sealing and protection performance.
[0046] The implementation principle of this application embodiment is as follows:
[0047] When the electricity metering box is used outdoors and is in a closed state, the box door 2 is rotated into the mounting groove 12 and locked in a detachable manner through a locking structure. The elastic sealing strip 21 on the box door 2 is compressed and in this state abuts against the inner wall of the mounting groove 12, which improves the sealing performance at the junction of the box body 1 and the box door 2.
[0048] Example 2:
[0049] Reference Figure 5 , Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that the outer side of the box 1 is provided with a protective component 3, wherein the protective component 3 includes an upper protective plate 31 and a lower protective plate 35 that are detachably installed on the upper and lower parts of the box 1, wherein the upper protective plate 31 and the lower protective plate 35 are used to seal the lateral gap between the box 1 and the box door 2.
[0050] Upper protective strips 32 are integrally formed on both ends of the upper protective plate 31, and lower protective strips 36 are integrally formed on both ends of the lower protective plate 35. The upper protective strips 32 and lower protective strips 36 are used to seal the vertical gap between the box body 1 and the box door 2.
[0051] Rubber sealing gaskets 39 are fixed on the sides of the upper protective plate 31, lower protective plate 35, upper protective strip 32 and lower protective strip 36 near the box body 1; when the box door 2 is closed, the protective component 3 is used to seal the gap between the box door 2 and the box body 1, and at this time the sealing gaskets 39 seal the corresponding gap positions.
[0052] Reference Figure 5 An upper positioning plate 33 that can abut against the upper side of the box body 1 is fixed on the side of the upper protective plate 31 away from the upper protective strip 32, and a lower positioning plate 37 that can abut against the upper side of the box body 1 is fixed on the side of the lower protective plate 35 away from the lower protective strip 36.

The control component 5 includes a control rod 51 that slides on the vertical side of the housing 1. A connecting rod 52 is fixedly provided at the lower ends of the two support rods 412. A connecting handle 53 is provided on the side of the connecting rod 52 away from the control rod 51.
[0058] The end of the control lever 51 away from the connecting rod 52 is provided with a guide slope 5111; when the user grips the connecting handle 53 and moves the control lever 51 upward, the control lever 51 can press against the support rod 412 along the guide slope 5111, causing the adjusting plate 41 to slide towards the door 2.
[0059] Reference Figure 7A support block 14 is fixed on the opposite vertical side of the housing 1. The support block 14 has a support through hole 141 for the control rod 51 to pass through. The control rod 51 has a waist-shaped control hole 512 along its own length. The support block 14 has an adjustment screw hole that communicates with the support through hole 141. The housing 1 has an adjustment bolt 54 that is screwed into the adjustment screw hole and then inserted into the waist-shaped control hole 512. The adjustment bolt 54 is a wing bolt, and the user can manually tighten or loosen the adjustment bolt 54.
[0060] Reference Figure 8 and Figure 9 The two upper protective strips 32 have upper sliding grooves 321 along the length direction on their respective sides, and the two lower protective strips 36 have lower sliding grooves 361 along the length direction on their respective sides.
[0061] The outer side of the box 1 is provided with a locking plate 7. A cleaning cotton 72 is fixed on the side of the locking plate 7 facing the box door 2. Positioning sliders 71 are fixed at both ends of the locking plate 7. The two positioning sliders 71 slide in the upper sliding groove 321 and the lower sliding groove 361. The locking plate 7 can slide to the junction of the upper sliding groove 321 and the lower sliding groove 361 and be fixed.
[0062] When the door 2 is closed, the locking plate 7 can be slid to the junction of the upper protective strip 32 and the lower protective strip 36 to lock the upper protective strip 32 and the lower protective strip 36 in this state; the locking plate 7 can also be slid up and down, and the outer surface of the door 2 can be cleaned with the cleaning cotton 72.
[0063] Reference Figure 10 and Figure 11 The positioning slider 71 is provided with an elastic snap-fit component 73, which includes a compression spring 731 and an arc-shaped protrusion 732. The positioning slider 71 is provided with a placement groove 711 for the compression spring 731 and the arc-shaped protrusion 732 to be placed. The compression spring 731 presses one side of the arc-shaped protrusion 732, causing a part of the arc-shaped protrusion 732 to protrude out of the placement groove 711. The protruding part of the arc-shaped protrusion 732 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. Furthermore, a plurality of positioning grooves 322 for the arc-shaped protrusion 732 to be snapped into are evenly provided on the inner walls of the upper sliding groove 321 and the lower sliding groove 361.
[0064] Reference Figure 8 and Figure 9 The locking plate 7 has adjustment protrusions 712 fixed at both ends, and the control rod 51 has an adjustment notch 513 at its end. When it is necessary to control the locking plate 7 to slide up and down, the user first removes the control rod 51 from the vertical side of the box 1, and then rotates the adjustment protrusions 712 into the adjustment notch 513. At this time, the user can operate the control rod 51 to drive the locking plate 7 to slide up and down.
[0065] The implementation principle of this application embodiment is as follows:
[0066] When the door 2 is closed, the upper positioning plate 33 and the lower positioning plate 37 abut against the upper and lower sides of the box body 1 respectively, and the end of the control rod 51 moves down and is misaligned with the end of the positioning rod 411. The upper protective strip 32 and the lower protective strip 36 abut against each other on their sides. Then, the locking plate 7 is slid to the junction of the upper protective strip 32 and the lower protective strip 36, and the locking plate 7 is used to lock the upper protective strip 32 and the lower protective strip 36 in this state.
[0067] When it is necessary to open the door 2, first remove the control lever 51 from the vertical side of the box body 1, then rotate the adjusting protrusion 712 into the adjusting notch 513, and then operate the control lever 51 to drive the locking plate 7 to slide up or down. The locking plate 7 slides to other positions, during which the outer side of the door 2 can be wiped clean. Then, slide the control lever 51 back onto the vertical side of the box body 1, slide the control lever 51 upward, and press the control lever 51 against the support rod 412 along the guide slope 5111 until the adjusting plate 41 slides towards the door 2, and finally the upper protective strip 32 and the lower protective strip 36 rotate away from the door 2, releasing the lock on the door 2.
