Technical Field

[0001] The utility model relates to the field of watt-hour meter installation structures, in particular to an watt-hour meter installation structure for a power distribution cabinet. Background Art

[0002] The distribution cabinet is the final equipment of the power distribution system. With the development of power technology and the continuous increase in power demand, the use of distribution cabinets is increasing, and some switch cabinets need to be equipped with electricity meters.

[0003] Most of the existing distribution cabinets are composed of cabinet bodies, cabinet doors, mounting brackets and electrical components. The watt-hour meter is generally installed inside the distribution cabinet by workers. The workers connect the electrical components inside the distribution cabinet to the watt-hour meter to detect and control the electrical components inside the distribution cabinet. At the same time, the electricity used by users is continuously recorded, which is very convenient and fast.

[0004] However, most of the existing installation structures between distribution cabinets and electricity meters are installed using fixed installation plates. Workers fix the electricity meter inside the cabinet by matching bolts and nuts. Since the electricity meter and the distribution cabinet are connected by bolts, when the electricity meter needs to be disassembled, workers need to disassemble multiple bolts, making this installation method inconvenient for installation operations and on-site maintenance, thereby greatly reducing work efficiency.

[0010] The utility model is further configured that an extension block is fixedly installed at one end of the cabinet, and the interior of the extension block is hollow, and a movable groove for the movable plate to move is opened at one end of the cabinet.

[0011] By adopting the above technical solution, the extension block arranged on the end face of the cabinet can provide space for the movable plate to move, and the movable groove can enable the movable plate to move out of the cabinet and into the extension block.

[0012] The utility model is further configured that one end of the movable plate is provided with a placement slot for placing an electric meter, and one end of the cabinet door is fixedly mounted with a first handle.

[0013] By adopting the above technical solution, the placement slot can provide a location for workers to place the electricity meter, helping workers to place the electricity meter better and faster. The first handle can facilitate workers to better pull the cabinet door and control the position and opening and closing of the cabinet door.

[0014] The utility model is further configured that the sliding rod, the sliding groove, the connecting rod and the spring are all symmetrically arranged in two groups.

[0015] By adopting the above technical solution, two sets of symmetrically arranged sliding rods and sliding grooves can provide moving space and restrictions for the movable plate, and ensure that the moving position of the movable plate will not be offset when the movable plate is subjected to force. Through two sets of symmetrically arranged connecting rods and springs, workers can better apply thrust to the limit plate when pushing the second handle, ensuring that the moving position of the limit plate will not be offset.

[0016] The utility model is further configured that a protrusion is fixedly mounted on one end of the limit plate, and a groove matching with the protrusion is provided inside the electric meter.

[0017] By adopting the above technical solution, a protrusion is fixedly installed at one end of the limit plate, and a groove matching the protrusion is opened inside the electric meter, so that when the limit plate contacts the electric meter, the protrusion enters the groove, thereby fixing and restricting the electric meter, ensuring that the position will not shift during the use of the electric meter, thereby affecting the use of the electric meter.
