Description

Technical Field

[0001] This utility model belongs to the technical field of electricity metering boxes, and more specifically, it relates to an assembled multi-position electricity metering box. Background Technology

[0002] A metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, and boxes. Metering boxes can be installed in a suspended or floor-mounted manner. To ensure installation quality, suspended boxes must be secured with built-in expansion bolts, and the bolt dimensions must meet safety and security requirements, as well as outdoor installation conditions.

[0003] Based on the above, the inventors have discovered the following problems: the current electricity metering boxes require the installation of multiple meters inside. However, due to the small internal space of the electricity metering box, it is very inconvenient for staff to install the meters, and it is also very troublesome to maintain them later. In addition, the position of the meters is not easy to adjust during installation, resulting in low space utilization.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a modular multi-position electricity metering box in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a modular multi-position electricity metering box, which solves the problems of the small internal space of current electricity metering boxes, making installation inconvenient for staff and causing significant trouble during later maintenance.

[0006] The purpose and function of this modular multi-position energy metering box are achieved by the following specific technical means:

[0007] A modular multi-position electricity metering box includes a box body with an opening and closing door. A movable frame is detachably installed inside the box body. Columns are installed on both sides of the movable frame. Limiting posts are installed on the columns, and sliders are slidably connected to the limiting posts. Mounting holes are provided on the upper and lower parts of the sliders and on the limiting posts. First bolts are installed inside the mounting holes, and the sliders are fixed to the limiting posts by the first bolts. Multiple sliders are arranged opposite each other. Connecting blocks are installed on the multiple sliders. Two sliders form a group, and groups of sliders are connected by a transverse rod. A notch is provided on the upper part of the limiting post, and the length of the notch is greater than the length of the slider.

[0008] Furthermore, guide strips are installed at the four inner corners of the housing, and guide grooves are provided on the four sides of the movable frame. The size of the guide grooves is adapted to the size of the guide strips, and the guide strips are located inside the guide grooves.

[0009] Furthermore, a movable groove is provided on the transverse rod, and a movable block is slidably connected to the transverse rod. A fastening bolt is threadedly connected to the movable block, and the lower end of the fastening bolt abuts against the upper part of the transverse rod.

[0010] Furthermore, a protrusion is installed in the middle of the movable block, the thickness of which is adapted to the thickness of the movable groove, and the protrusion is located inside the movable groove.

[0011] Furthermore, an extension rod is installed on the side of the movable block, and the movable block is connected to a mounting plate via the extension rod.

[0012] Furthermore, buffer rods are installed on both the upper and lower parts of one side of the movable frame, with one end of the buffer rod abutting against the inside of the opening and closing door.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the slider and the limiting post are slidably connected through the notch. The horizontal rod and the slider are moved to the lower part, and then the slider is fixed by the first bolt. Then the fastening bolt is loosened, and the moving blocks are pushed left and right. The distance between the moving blocks is adjusted according to the model of the electricity meter. After the adjustment is completed, the moving blocks are fixed by the fastening bolt. At this time, the electricity meter can be installed on the mounting plate. The installation distance between the upper and lower electricity meters can be adjusted, as can the installation distance between the horizontal electricity meters. The space utilization rate is high.

[0015] In this invention, by pulling the moving frame outward, the guide groove and guide bar work together to make the movement of the moving frame more stable and facilitate subsequent installation. Moving the moving frame to the outside makes it convenient for maintenance. When the door is closed, the door contacts the buffer rod, which can buffer the opening and closing of the door and reduce noise. Attached Figure Description
