Description

Technical Field

[0001] The utility model relates to the technical field of meter boxes, in particular to a low-voltage single-phase multi-meter meter box. Background Art

[0002] A meter box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including energy meters, voltage and current transformers and their secondary circuits, energy metering panels, cabinets, and boxes. A multi-meter meter box is a box capable of housing multiple energy meters simultaneously and is suitable for scenarios requiring centralized metering of the electricity consumption of multiple users or devices.

[0003] The multi-meter meter boxes currently on the market face a significant practical problem: the need to simultaneously install multiple energy meters or meters within the limited space of the box makes the internal installation space extremely narrow. This compact layout not only greatly increases the difficulty of meter installation, making it difficult for workers to accurately locate and secure the meters within the confined space. A slight mistake could damage the equipment or affect the quality of the installation. It also poses a huge challenge to cable routing. Numerous cables need to be properly routed within the limited space to avoid cross-entanglement, ensuring both safe and reliable electrical connections and facilitating subsequent maintenance and repair. Improper cable routing can not only cause safety hazards such as short circuits, but also complicate and tedious subsequent troubleshooting and repair work, consuming significant time and labor costs, and thus affecting the stable operation and efficiency of the entire power metering system.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] The low-voltage single-phase multi-meter meter box includes a back plate 1, an intermediate shell 2 and a front panel 3. There is no limitation on the specific materials of the back plate 1, the intermediate shell 2 and the front panel 3. For example, they can be made of galvanized steel plate.

[0022] In this embodiment, the intermediate housing 2 is disposed between the back panel 1 and the front panel 3. Together, the back panel 1, the intermediate housing 2, and the front panel 3 form a mounting space for accommodating multiple meters. Furthermore, a mounting plate 4 for mounting the meters is fixedly mounted on the front of the back panel 1. A gap is provided between the mounting plate 4 and the back panel 1 to accommodate wires. The mounting plate 4 has multiple holes for mounting meters, switches, and other devices. The front of the back panel 1 refers to the side of the back panel 1 that is closest to the front panel 3.

[0023] The front panel 3 includes a panel frame 31 and a first door 32 and a second door 33 hingedly mounted on the panel frame 31 . The first door 32 and the second door 33 are used to open and close the installation space inside the metering box.

[0024] The back of the back panel 1 is abutted against and fixed on a carrier, which may be a wall or the like. The front panel 3 is fixedly connected to the front of the back panel 1 via fasteners 6, so that the intermediate shell 2 is squeezed and fixed to the back panel 1 via the front panel 3. In this embodiment, the fasteners 6 may be hexagon socket bolts or hexagonal bolts, etc.

[0025] During actual installation, first install the back panel 1 on a wall or other supporting object, then fix the mounting plate 4 to the back panel 1, and then install the meters on the mounting plate 4 in the appropriate order. After all the meters and other structures are installed, use the fasteners 6 to install and fix the front panel 3 to the back panel 1, so that the front panel 3 squeezes and fixes the intermediate shell 2 on the back panel 1, completing the installation of the entire meter box.

[0026] In the present invention, the back panel 1, the middle shell 2 and the front panel 3 constituting the meter box are set as a detachable structure. During actual installation, the back panel 1 with the mounting plate 4 is first mounted on a supporting object such as a wall, and then the meter is mounted on the mounting plate 4. Finally, the middle shell 2 is squeezed and fixed on the back panel 1 using the front panel 3, and the installation of the entire meter box is completed. In this way, during the installation of the meter, since the middle shell 2 and the front panel 3 constituting the meter box are not connected to the back panel 1, the installation of the meter will not be blocked, and sufficient operating space is reserved for the staff, thereby reducing the difficulty of installing the meter and the difficulty of arranging the wires.

[0027] In order to improve the structural strength of the metering box, a structure for supporting the four inner corner positions of the intermediate shell 2 is also provided in this embodiment. Specifically, support columns 5 are fixedly provided at the four corner positions on the front of the back panel 1. In this embodiment, the support columns 5 and the back panel 1 can be fixedly connected by bolts. The support columns 5 correspond to the corner positions of the back panel 1 adjacent to them as right-angle portions 51, that is, the corner positions of the support columns 5 close to the back panel 1 are right-angle portions 51. The four support columns 5 have a total of four right-angle portions 51. The four right-angle portions 51 are used to support the four inner corners of the intermediate shell 2 respectively, thereby ensuring the structural strength of the metering box at the four corner positions of the intermediate shell 2. At the same time, under the action of the four support columns 5, the part of the intermediate shell 2 located between two adjacent support columns 5 will also be pulled and kept flat.

[0028] The corners of the front panel 3 are mounted against the end faces of the support columns 5 away from the back panel 1 via fasteners 6. Furthermore, the support columns 5 are hollow square tubes, with connectors 52 fixedly disposed at the ends of the support columns 5 away from the back panel 1. The connectors 52 are in the shape of a quadrangular pyramid, which facilitates the connection of the intermediate housing 2 to the four support columns 5 and provides anchor points for the fasteners 6.

[0029] As can be seen from the figure, a lining 7 is fixed between two support columns 5 adjacent horizontally or vertically. The four linings 7 cooperate with the four right-angle portions 51 to form a rectangular enclosure. The rectangular enclosure is used to support the inner wall of one end of the intermediate shell 2 away from the front panel 3. One end of the lining 7 is fixedly connected to the back panel 1, and the other end of the lining 7 is fixedly provided with an inwardly inclined guide piece 71, which is used to allow the intermediate shell 2 to be smoothly mounted on the rectangular enclosure.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
