Description

Technical Field

[0001] The present invention relates to the field of electric meters, and in particular to an electric meter box which is convenient for assembly and disassembly. Background Art

[0002] The meter box is a device used to store electricity meters. According to electrical wiring requirements, switchgear, measuring instruments, protective electrical equipment and auxiliary equipment are assembled in the meter box, and the market often has protection grade requirements for meter boxes.

[0003] To facilitate meter reading and regular meter maintenance, most existing meter boxes consist of a housing and a lid attached to one side. The housing has a forward-facing storage chamber, while the lid pivots on the bottom of the box and is used to open and close the chamber. The lid and housing utilize a conventional hinged connection, a relatively traditional method. The hinge is typically made of metal and needs to be assembled and fixed to the meter housing, resulting in a complex and costly production process. Furthermore, meter boxes are often used outdoors, and the hinges are susceptible to corrosion in humid environments, increasing long-term maintenance costs. When the meter box needs to be disassembled for maintenance or component replacement, the hinged housing and lid are inconvenient to remove.

[0004] In the prior art, a connecting shaft is also used to fix the box cover and the box body. However, when the box cover is opened, the box cover is easily detached from the box body along the installation path.

[0005] Therefore, it is necessary to improve the existing electric meter box structure. Summary of the Invention

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-4 The preferred embodiment of the present invention is shown in FIG.

[0029] The front side of the box body 1 has a mounting opening 1 a.

[0030] The box cover 2 is opened and closed at the installation opening 1 a of the box body 1 .

[0031] One side of the housing 1 is provided with a first limiting portion 11, a first mounting portion 12, and a reinforcing rib 14. The first limiting portion 11 has a guide surface 11a on one side. The guide surface 11a has a first end and a second end corresponding to the first end. The distance between the guide surface 11a and the housing 1 gradually increases from the first end to the second end. The first limiting portion 11 has a first weight-reducing groove 111. The first mounting portion 12 includes a guide portion 121 and a clamping portion 122.

[0032] A first through hole 123 is formed at one end of the guide portion 121. The end of the connecting shaft 3 extends through the first through hole 123 into the first mounting portion 12. The clamping portion 122 is used to clamp the end of the connecting shaft 3 and is located within the guide portion 121. The top end of the first mounting portion 12 is open, and correspondingly, the bottom end of the second mounting portion 22 is open.

[0033] A second limiting portion 21 is provided on one side of the box cover 2, and the second limiting portion 21 abuts against the first limiting portion 11 and is close to the second end of the guide surface 11a. A reinforcing rib 14 connected to the first limiting portion 11 is provided on the side of the box body 1. The second limiting portion 21 has a second weight-reducing groove 211. There are multiple first mounting portions 12, and correspondingly, multiple second mounting portions 22 are provided on the side of the box cover 2. Each first mounting portion 12 is located at the bottom end of the second mounting portion 22 corresponding to the first mounting portion 12; the first limiting portion 11 is located at the top end of the second limiting portion 21. Therefore, the box cover 2 is limited and will not fall off. The box cover 2 is a combination of one or more of polycarbonate and glass fiber, and has a certain hardness and deformability, which makes it easy to install, but it is difficult to self-deform and fall off when there is no external force.

[0034] A first fixing portion 13 is provided on the other side of the box body 1, and a corresponding second fixing portion 23 is provided on the box cover 2. The meter box also includes a connector 4 for securing the first fixing portion 13 to the second fixing portion 23. Both the first fixing portion 13 and the second fixing portion 23 are provided with through-holes. During installation, a connecting tool such as a connecting rope or a buckle is passed through the through-holes to secure the first and second fixing portions 13, 23, thereby securing the box cover 2 to the box body 1. To operate the meter inside the box, the connecting tool is removed and the box cover 2 can be flipped over.

[0035] One end of the connecting shaft 3 is disposed in the first mounting portion 12 , and the other end is disposed in the second mounting portion 22 .

[0036] The installation process of this embodiment is as follows:

[0037] First, one end of the connecting shaft 3 is set in the first mounting portion 12, and then the other end of the connecting shaft 3 is aligned with the second mounting portion 22. The box cover 2 is moved so that the connecting shaft 3 enters the second mounting portion 22. At this time, since the distance between the guide surface 11a and the box body 1 gradually increases from the first end to the second end, during the installation of the box cover 2, the second limiting portion 21 moves along the guide surface 11a. After being installed in place, the second limiting portion 21 is set at the second end of the guide surface 11a. At this time, the second end prevents the second limiting portion 21 from moving, thereby limiting the position of the box cover 2.
