Description

Technical Field

[0001] The utility model relates to the field of electric energy metering boxes, in particular to a protection structure for an electric energy metering box. Background Technique

[0002] An electric energy metering box is a metering instrument used to measure and record power generation, power supply (mutual power supply), plant power consumption, line loss power, and user power consumption. An electric energy metering device refers to a protective box body composed of an electric energy meter (active and reactive electric energy meters, maximum demand meters, multi-rate electric energy meters, etc.), metering transformers (including voltage transformers and current transformers), and secondary connection wires.

[0003] Most of the traditional improvements in the protection of electric energy metering boxes are aimed at waterproofing, sealing, internal explosion protection, etc. Since the outer cover plate of the electric energy box is generally made of transparent acrylic material, it is easily damaged under external force, and then the internal equipment of the electric energy metering box is damaged. Therefore, the utility model proposes a protection structure for an electric energy metering box. The protection rod arranged can move above the cover plate under the drive of the adjusting screw. When the cover plate is not opened, the protection rod protrudes from the plane of the cover plate, and the protection rod can play a protective role. At the same time, in order to further expand the protection range of the protection rod, the elastic protection components arranged can move on the protection rod. During use, by adjusting multiple groups of elastic protection components to be equidistant on the protection rod, the protection of the cover plate can be realized. Content of the Utility Model

[0004] The purpose of the utility model is to provide a protection structure for an electric energy metering box to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A protection structure for an electric energy metering box, the protection structure is installed on the front side of the metering box, and the protection structure includes:

[0006] A cover plate, which is hinged to the front opening of the metering box through a hinge shaft. The cover plate is made of transparent acrylic material, and there are marks on the cover plate. The cover plate can rotate relative to the hinge shaft and cover the opening of the metering box;

[0007] Two groups of chute components, distributed on the left and right sides of the front side of the metering box. Each group of chutes includes two chutes arranged vertically. An adjusting screw is provided outside each chute;

[0008] Two groups of protection rods, which are vertically arranged on the front side of the metering box. A sliding rod is vertically connected to the top and bottom ends of each protection rod, and the sliding rod extends into the chutes distributed on the upper and lower sides of the metering box. The sliding rod can move along the length direction of the chute and drive the protection rod to approach or move away from the cover plate.

[0009] Preferably, a knob is provided at the end of the adjusting screw, and its front end extends into the chute and is connected to the sliding rod. The adjusting screw can drive the sliding rod to move along the chute.

[0010] Preferably, a plurality of elastic protection components are arranged along the length direction of the protection rod, and each group of elastic protection components includes a sliding sleeve and an elastic band.

[0011] Preferably, the sliding sleeve is movably sleeved outside the protection rod, and the sliding sleeves on the two protection rods are connected by an elastic band.

[0012] Preferably, the elastic band is an elastic rubber cord with elasticity inside. The elastic band can be in a contracted state when the two protection rods approach each other, and the elastic band can be in an extended state when the two protection rods move away from each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
