Description

Technical Field

[0001] The utility model relates to the technical field of electric energy metering boxes, in particular to a split-assembled electric energy metering box. Background Technique

[0002] In daily life, the box for installing an electric meter is called an electric energy metering box, which is commonly known as a low-voltage plastic transparent electric energy metering box. Traditional electric energy metering boxes only have a structure, and the electric meters are all assembled in the outer box. Limited by the size of the outer box, it is difficult to install a large number of electric meters in the box body. Therefore, each floor of a residence shares a metering box, but a metering box needs to be set on each floor, and it is difficult to achieve multi-floor sharing. Then the number of metering boxes put into use will increase, and the corresponding cost will also increase. Moreover, users need to copy the electricity consumption data floor by floor, with high work intensity and low efficiency.

[0003] The patent with the publication number CN220673175U discloses a split-assembled electric energy metering box, including a main box body. Both sides of the main box body are fixedly connected with mounting rails. A mounting plate is detachably mounted on the surface of the mounting rail on one side of the main box body. One end of the inner side of the mounting plate is fixedly connected with a first pressing plate. The top of the first pressing plate is fixedly connected with evenly distributed brackets. A positioning pin is arranged through the top of the brackets. A baffle located inside the brackets is fixedly connected to the surface of the positioning pin. The utility model adopts the structural design of a split-assembled metering box, designs the metering box into a main box and a sub-box. The number of sub-boxes can be increased or decreased according to actual situations and usage requirements. The sub-box can be assembled onto the main box according to installation requirements or separated from the main box. The assembly position of the sub-box can also be flexibly set. Such a structural design is more flexible for users to use and provides convenience for users.

[0004] Although the above-mentioned prior art can select the number of sub-boxes according to actual situations and usage requirements, and the sub-box can be assembled onto the main box or separated from the main box according to installation requirements, the first pressing plate and the second pressing plate are both fixed on the mounting plate. A plurality of brackets are fixedly connected to the first pressing plate. Each bracket is connected with a positioning pin, a baffle and a spring. However, a sufficient number of sub-boxes are often not installed on the mounting plate, resulting in some brackets being in an unused state, and the positioning pins, baffles and springs installed on the unused brackets are also in an unused state, leading to a waste of a large number of parts and an increase in the usage cost. In view of this, we propose a split-assembled electric energy metering box. Content of the Utility Model

[0005] The purpose of the utility model is to provide a split-assembled electric energy metering box to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:
