[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the present invention, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or interactions between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected only through a connecting structure to form a whole. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] In the present invention, Figure 1-7 As shown in the figure, an electric energy meter box is provided, including a panel 1, which can be used to install electrical components; an installation box, including two boxes 2 that can be spliced ​​together along a splicing direction, the splicing direction is perpendicular to the thickness direction of the installation box, and the two boxes 2 are respectively provided with a clamping structure. When the two boxes 2 approach each other along the splicing direction, the clamping structures of the two boxes 2 can be clamped together, and the two boxes 2 are spliced ​​into a box structure that can accommodate the panel 1. When the two boxes 2 move away from each other along the splicing direction, the clamping structures of the two boxes 2 can be separated, wherein at least one box 2 is formed with a through groove 3 extending along the splicing direction, the through groove 3 penetrates to the splicing side of the box 2, and the through groove 3 allows a connector to pass through to install the panel 1 on an external component.

[0029] As shown in the figure, when the meter box of the present invention is used, the two boxes 2 are moved along the splicing direction. After the snap-fit ​​structures of the two boxes 2 are snap-fitted to each other, the two boxes 2 are spliced ​​together to form a box structure. Then, the panel 1 with the electrical components installed is placed inside the box structure. The box 2 is then fixed to an external component (such as a wall) through a connector. Specifically, the connector passes through the through groove 3 and is connected to the panel 1, and the connector supports the box 2 at the through groove 3. When the box 2 is damaged, the two boxes 2 can be directly pulled apart along the splicing direction to separate the snap-fit ​​structures of the two boxes 2, and the box 2 damaged along the splicing direction can be removed. Then, the new or repaired box 2 can be moved along the splicing direction and installed in the installation position.

[0030] It is not difficult to see from this that when the metering box of the present invention is in use, the box-like structure that accommodates electrical components is divided into two parts. When the box body 2 is partially damaged, only the corresponding box body 2 needs to be replaced, and there is no need to replace the entire box-like structure, which saves materials.

[0031] What is particularly important is that the present invention is provided with two separable boxes 2. After the entire metering box is installed in the installation position, when it is necessary to remove the box 2, since the panel 1 is connected to the installation component through the connector passing through the through slot 3, there is no need to move the panel 1 relative to the external component, and the damaged box 2 can be directly removed along the splicing direction. In this process, when it is necessary to move the box 2 with the connector passing through the through slot 3, the connector can be moved relative to the box 2 in the through slot 3, and the relative position of the panel 1 and the external component remains unchanged. There is no need to remove the electrical component from the external component, so that the line connection of the electrical component will not be affected by the movement of the electrical component, so that the box 2 can be installed or removed without interrupting the power supply.

[0032] Moreover, the two boxes 2 of the present invention are connected to each other through a snap-fit ​​structure. When the boxes 2 are reinstalled at the installation component, the two boxes 2 can be spliced ​​and fixed by simply moving the boxes 2 along the splicing direction, which makes the operation easier.

[0033] Moreover, in the present invention, by providing a panel 1 for installing electrical components and two boxes 2, the flexibility of the meter box during use can be improved. Specifically, as shown in the figure, the two boxes 2 can correspond to different installation areas, wherein the smaller box 2 can be used to place electrical components such as switches, and the smaller box 2 can be used to place electric meters. In this way, boxes 2 of different sizes corresponding to the areas where electric meters are placed can be processed, so that the corresponding panel 1 and box 2 can be selected according to the actual number of electric meters required, so that the smaller box 2 can form a universal module, thereby increasing the flexibility of the use of the present invention.

[0034] Furthermore, in an embodiment of the present invention, the panel 1 is directly connected to external components via connectors, eliminating or reducing the support force of the mounting box on the electrical components. This reduces the force applied to the mounting box during use, lowering the support strength requirements for the mounting box, and reducing the risk of deformation and damage to the mounting box due to high forces. Specifically, the connectors can be expansion bolts.

[0035] In the embodiment shown in the figure, more specifically, the panel 1 is connected to the two boxes 2 by bolts. Figure 2 and Figure 3 As shown, the meter box is provided with a total of one panel 1, and the panel 1 is connected to the box body 2 at its four corners by bolts respectively, so that after the panel 1 is installed in the box body 2, the panel 1 and the two box bodies 2 are connected into one, which increases the structural integrity and strength of the entire meter box. Especially before it is installed to the external components, the structural stability of the entire meter box can be achieved by connecting the clamping structures of the two box bodies 2 and the panel 1 and the two box bodies 2. During the transportation process, the two box bodies 2 of the meter box are prevented from being separated and damaged. During the initial installation on site, it is only necessary to connect the connecting piece to the external component, and then pass the connecting piece through the through slot 3 to connect it to the panel 1.

[0036] It should be noted that, in alternative embodiments, the panel 1 may not be connected to the housing 2. The provision of a single integral panel 1 is not intended to limit the present invention. In alternative embodiments, multiple panels 1 may be provided, each of which is fixed to an external component via a connector. In this case, the panel 1 may be connected to the housing 2, or it may not be connected to the housing 2.

[0037] In order to further facilitate the disassembly and assembly of the two boxes 2 and improve the strength of the connection between the two boxes 2, in the illustrated embodiment, a further optimization is that at least two snap-fit ​​structures are provided at intervals along the abutting direction extending from the splicing side of the boxes 2; one of the two boxes 2 is formed with a guide post 4 extending along the splicing direction, and the other is formed with a slot 5 for the guide post 4 to be inserted, and the guide post 4 and the snap-fit ​​structure are arranged alternately along the abutting direction. Figure 3 and Figure 4 As shown, by providing the guide column 4 and the slot 5, the two boxes 2 can be aligned relatively easily when they are spliced ​​together along the splicing direction, especially when the box 2 is reinstalled at the external component, the guiding cooperation of the guide column 4 and the slot 5 can reduce the problem of difficulty in alignment caused by obstruction of the panel 1.

[0038] The beneficial effect of providing the guide posts 4 and the slots 5 is that, after being inserted into the slots 5, the guide posts 4 can form a certain constraint on the two boxes 2, thereby preventing the two boxes 2 from moving relative to each other in a plane perpendicular to the splicing direction. In particular, when transporting the assembled installation box, the shear force perpendicular to the splicing direction on the clamping structure can be further reduced, thereby reducing the probability of damage to the clamping structure due to shear force. Moreover, by staggering the guide posts 4 and the clamping structure along the abutment direction, the two boxes 2 can be evenly aligned at the splicing position, and the clamping structure can be evenly constrained in the abutment direction.

[0039] In the embodiment shown in the figure, a further optimization is that the box body 2 is formed with an outwardly protruding abutment block 6, the abutment block 6 is formed with a guide column 4 and / or a slot 5, and when the two boxes 2 are assembled, the abutment blocks 6 of the two boxes 2 abut against each other. Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the abutment blocks 6 formed thereby further increase the strength of the box body 2 at the joint, allowing the two boxes 2 to transmit abutment forces in the joint direction more evenly, thereby preventing the box body 2 from being locally deformed at the joint. In the illustrated embodiment, the abutment blocks 6 protrude into the storage space of the box body 2, thereby increasing the size of the abutment surfaces of the two boxes 2 in the thickness direction of the box body 2. When the installation box is being carried and the installation box is approximately horizontal, when an upward lifting force is applied at both ends of the box body 2, the upward force will form an upward rotational moment at the joint of the two boxes 2. The abutment force arm of the abutment blocks 6 is longer, thereby reducing the force transmitted by the abutment blocks 6, and the abutment blocks 6 can be more stable, thereby preventing the installation box from breaking at the joint position, thereby improving the stability of the box body 2.

[0040] As for the specific form of the snap-fit ​​structure, in the illustrated embodiment, to be more specific, one of the snap-fit ​​structures is a snap-fit ​​block 7 formed on the box body 2, the snap-fit ​​block 7 includes a connecting rib 701 connected to the box body 2, and a snap-fit ​​protrusion 702 formed on the side of the connecting rib 701 away from the box body 2, the connecting rib 701 extends along the splicing direction, and the cross-section of the snap-fit ​​protrusion 702 is arc-shaped; the other snap-fit ​​structure is an arc-shaped snap-fit ​​member 8 arranged on the other box body 2, the arc-shaped snap-fit ​​member 8 is formed with an arc-shaped slot, and the snap-fit ​​protrusion 702 can be squeezed into the notch of the arc-shaped slot.

[0041] like Figure 2 and Figure 5 、 Figure 6As shown, the cross-section of the arcuate slot is smaller than the profile of the engaging protrusion 702. When the two boxes 2 are joined, the engaging protrusion 702 is squeezed into the slot of the arcuate slot. During this process, the arcuate slot is first stretched and deformed. After the engaging protrusion 702 is squeezed in, the arcuate slot returns to its original shape, locking the engaging protrusion 702 in, thus completing the connection of the engaging structure. When the two boxes 2 are separated, the engaging protrusion 702 stretches the arcuate slot open, and then the engaging protrusion 702 separates from the arcuate slot, allowing the two boxes 2 to be separated.

[0042] In order to facilitate the engagement protrusion 702 to enter or squeeze out of the arc-shaped slot and ensure the engagement force of the arc-shaped slot on the engagement protrusion 702, preferably, the central angle of the arc-shaped slot is greater than or equal to 260° and less than or equal to 280°. In the illustrated embodiment, specifically, the central angle of the arc-shaped slot is set to 270°.

[0043] For the illustrated embodiment, further optimization is that the box body 2 includes a bottom plate 201 and a side plate 202 formed on the edge of the bottom plate 201. After the two box bodies 2 are spliced ​​together, the side plates 202 of the two box bodies 2 are enclosed to form the side walls of the box structure; the side plates 202 are formed with an insertion cavity 9 perpendicular to the bottom plate 201 at the splicing position of the two box bodies 2, and the metering box also includes a pin 10 with two insert ribs 1001, and the two insert ribs 1001 can be respectively inserted into the two insertion cavities 9 on the same side of the box structure.

[0044] like Figure 6 and Figure 7 As shown, the side panels 202 of the box body 2 are generally U-shaped. When the two box bodies 2 are spliced ​​together, the two ends of the side panels 202 are respectively located at the splicing positions. The present invention provides dowels 1001 and insertion cavities 9. After the box bodies 2 are spliced ​​together, the two dowels 1001 of the latch 10 are respectively inserted into the two insertion cavities 9, so that the ends of the side panels 202 of the two box bodies 2 can be aligned, further improving the integrity of the installation box. The latch 10 can also limit the separation of the two box bodies 2.

[0045] In the embodiment shown in the figure, a further optimization is that the side plate 202 of the box body 2 is formed with a wire notch 11 at one of the insertion cavities 9, and the metering box further includes a wire plate 12, which is inserted into the side plate 202 in a direction perpendicular to the bottom plate 201, and the wire plate 12 and the side plate 202 enclose the wire notch 11, and the wire plate 12 has a positioning hole 13 connected to the insertion cavity 9, and the insert 1001 passes through the positioning hole 13 and is inserted into the insertion cavity 9. Figure 6 and Figure 7As shown, the two boxes 2 at one end of the installation box are respectively provided with wire notches 11. During installation, the wires of the electrical components in the installation box can be passed through the wire notches 11. When the box 2 needs to be replaced, it is only necessary to pull out the pin 10 and remove the wire plate 12. At this time, the wires can be taken out from the wire notches 11. At this time, the box 2 can be moved along the splicing direction to be removed and installed without moving the panel 1 and disassembling the wires and electrical components.

[0046] The latch 10 can not only align the side panels 202 of the two boxes 2 , but also fix the wire guide 12 .

[0047] In the illustrated embodiment, a further optimization is that the sidewall of the insertion cavity 9 facing the side of the housing 2 that is to be joined is formed with an opening, and the latch 10 also includes a transverse rib 1002 connecting the two insert ribs 1001. When the insert ribs 1001 of the latch 10 are inserted into the insertion cavity 9, the transverse rib 1002 passes through the opening. As shown in the figure, the cross section of the insertion cavity is generally L-shaped, while the cross section of the latch 10 is U-shaped. This prevents the two insert ribs 1001 of the latch 10 from separating and deforming outward, thereby preventing relative movement of the side panels 202 of the two housings 2.

[0048] For the embodiment shown in the figure, a further optimization is that two positioning ribs 14 are formed in the box body 2. After the two boxes 2 are assembled, the four positioning ribs 14 of the two boxes 2 can respectively abut against the four corners of the panel 1 for positioning. Figure 2 and Figure 3 As shown, the positioning ribs 14 are arc-shaped, and the four corners of the panel 1 are arc-shaped. When installing the panel 1, the panel 1 can be quickly placed in the designated position of the installation box.

[0049] In the specific application of the present invention, the following can be set on the opposite side of the bottom plate 201 of the box body 2: Figure 1 The door 15 shown, after the two boxes 2 are assembled, the doors 15 of the two boxes 2 can be closed or opened to install the box. Wherein, the door can be arranged to be detachably connected to the box, so that when the door is intact and the box is replaced, the door can be reused.

[0050] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0051] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
