Description

Technical Field

[0001] The utility model relates to the technical field of fixed brackets, in particular to a fixed bracket for an electric energy metering device. Background Art

[0002] An electric energy metering device, or electric meter, is an instrument used to measure electric energy. As a terminal used to measure user electricity consumption in power transmission, electric meters are widely used in power supply. Electric meters are indispensable in the lives of every household and are updated quickly. The installation and replacement of electric meters are common work contents in the field of power transmission. At present, the installation method of electric meters is usually to install them directly on the fixed surface and use three-point fixing. During the installation process, holes are first drilled on the inner plate of the electrical box or the wall according to the installation holes of the electric meter, and then they are installed and fixed with bolts, screws and other fixings.

[0003] At present, the external dimensions of electric meters are not uniform. Although the standard GB / Z21192-2007 "Electric Energy Meter External Dimensions and Installation Dimensions" provides external dimension regulations for single-phase and three-phase electric energy meters, as well as recommended preferred parameters, a large number of external dimension solutions can still be combined according to the data given by the national standard, which results in various sizes of electric energy meters mounted on site, exceeding hundreds of sizes, adding a lot of inconvenience to the management of electric energy meters and the subsequent replacement of electric energy meters. The installation method of electric meters is usually three-point fixing, and there are also four-point fixing electric energy meters. The number and position of the installation holes of electric energy meters of different sizes are different, resulting in that when replacing the electric energy meter, the original installation hole is no longer applicable and needs to be re-drilled, which makes it inconvenient to replace the electric energy meter, so a fixing bracket (with a fixing bracket) for electric energy metering device is provided. The invention relates to a fixed energy metering device, wherein the fixing plate, the mounting plate and the movable plate are arranged in an "I" shape; the fixing plate is provided with a sliding hole and at least two fixing holes, the sliding hole is a long hole and extends in a vertical direction; the mounting plate is fixedly connected to the fixing plate, and a first mounting hole is provided on the mounting plate, the first mounting hole is a long hole or a plurality of circular holes arranged at intervals; the movable plate is slidably connected to the fixing plate, the movable plate can slide along the length direction of the sliding hole and can be fixed at a desired position, and a second mounting hole is provided on the movable plate, the second mounting hole is a long hole or a plurality of circular holes arranged at intervals. The electric energy metering device fixing bracket solves the problem of inconvenience in replacing electric meters caused by the inconsistent number and position of mounting holes of different electric meters in the prior art.

[0004] However, some existing electric energy metering device fixing brackets can only realize some simple installation and fixing operations, and the installation and fixing are relatively unstable, which often leads to the falling off of the device. At the same time, there is only one fixing method, and the usage scenario is relatively single, which affects the use effect. In addition, some electric energy metering device fixing brackets are large in size, inconvenient to use, and have poor practicality. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing bracket for an electric energy metering device in order to solve the problems that some existing fixing brackets for electric energy metering devices can only realize some simple installation and fixing operations, and the installation and fixing are relatively loose, which often leads to the falling off of the device, and there is only one fixing method, the usage scenario is relatively single, which affects the use effect, and some fixing brackets for electric energy metering devices are large in size, inconvenient to use, and have poor practicality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing bracket of an electric energy metering device, comprising a shell, mounting parts are arranged at the four corners of the shell, the mounting parts include a connecting frame, a fixing plate is arranged on the side of the connecting frame away from the shell, a groove is arranged at the bottom of the connecting frame, baffles are arranged on both sides of the bottom of the groove, fixing parts are arranged on both sides of the shell, the fixing parts include a limit block, a rotating shaft is arranged on both sides of the limit block, rotating wheels are arranged inside the two groups of rotating shafts, a clamping block is arranged on the side of the two groups of rotating wheels away from the limit block, a clamping groove is arranged on the side of the two groups of clamping blocks away from the rotating wheel, and a clamping part is arranged inside the shell.

[0007] As a further solution of the utility model: a rotating plate is provided at the bottom of the clamping frame, and the clamping frame is rotatably connected to the housing through the rotating plate.

[0008] As a further solution of the utility model: a plurality of groups of the shells are fixedly connected to each other through limiting blocks, limiting grooves, clamping blocks and clamping grooves.

In the process of connection, the two groups of card blocks first pass through the blocking of the limit slots, so that they can rotate through the mutual cooperation with the rotating shaft. At the same time, after the last two groups of card blocks pass into the two groups of card slots, due to the absence of the blocking of the limit slots, the two groups of card blocks are rotated back to the initial position through the elastic force of the rotating wheel, so that the limit blocks pass through the two groups of card slots and the limiting operation of the two groups of card blocks, so that they are locked with the limit slots, and the connection and fixing operation of each device is completed. This device can meet the connection and fixing operation of different numbers of devices, and the connection and fixing is more convenient and quick, and has strong practicality;

If it is wall-mounted, just make a mounting groove at the mounting position, place the fixing plate at the corresponding mounting position, and then pass the fixing screws through the mounting holes in sequence to fix the device on the wall. If it is wire-hanging installation, move the fixing part to the top of the fixed cable, move the groove to the top of the fixed cable, and then push the connecting frame downward. The fixed cable pushes the two sets of baffles inward. After the fixed cable is moved to the inside of the groove, the two sets of baffles are rotated back to their original positions under the elastic force of the connecting rod to complete the wire-hanging installation.
