A combined concave sealed distribution box

Abstract

The invention belongs to the technical field of power distribution, and relates to a sealing power distribution box of a novel structure, in particular to a combined-type concaved sealing power distribution box. The main structure of the combined-type concaved sealing power distribution box comprises a box body, cover body bolt holes, a sealant groove, upper fixing holes for an electricity meter, bottom shell bolt holes, a circular lead hole, a one-way breathable valve, electricity meter fixing grooves, a cover body, side face connecting holes, side prisms, lower fixing holes for the electricity meter and a rubber fastening ring. According to the combined-type concaved sealing power distribution box, the sealing property of the power distribution box is guaranteed through the sealant groove, the circular lead hole and the one-way breathable valve which are arranged in the power distribution box, therefore, the working environment in the power distribution box is stable and safe, and multiple power distribution boxes can be combined to be used through the side face connecting holes. The combined-type concaved sealing power distribution box is simple in structural design, good in sealing property, stable in working environment, light and portable in appearance, flexible and simple in assembling concept, low in manufacturing cost and good in safety.

Description

Technical field: [0001] The invention belongs to the field of power distribution technology, and relates to a combined concave sealed power distribution box, in particular to a concave sealed power distribution box with a combination of basic power distribution boxes of various shapes. The side connection holes, the screw holes of the bottom case and the connection pin device realize the assembly of the concave distribution box. Background technique: [0002] The distribution box or meter box is a device used to install devices such as meters and switches. It is very common in daily life or various construction occasions, and is an indispensable equipment in the power supply department. First of all, people’s daily electricity consumption mostly adopts the one-meter-one-household system. In order to strengthen management, the power department usually uses multi-meter meter boxes to centrally install users’ electricity meters. Although the management is convenient, during th...

Problems solved by technology

Although the management is convenient, during the installation process, the power supply switch and the electric meter are installed in one box, which is easy to make mistakes when wiring, and it is not easy to find the faulty electric meter during maintenance; secondly, the shape of the integral power distribution box is large and It cannot be changed, and it cannot be adjusted according to the spatial structure of the working environment, which will easily lead to the inability to make full use of the space, and it may also easily lead to the inability to install in a small space; thirdly, in some outdoor operations, the number of electric meters usually required is small, and the overall Type electric meter box is extremely inconvenient in carrying, installing, also can't make the best use of everything simultaneously, causes waste; There are still many problems unresolved in this kind of collective electric meter box assembly

One is that each meter box of this collective meter box assembly is a cuboid of the same specification, and it is impossible to assemble a distribution box structure with more structural shapes in different work spaces, and the ability to cope with the working environment is poor; The reason is that the box body of the meter box does not have airtightness, the inside of the box body of the meter is easy to enter moisture, and it is attached to the inside of the box cover, which makes it difficult to read. At the same time, the humid box environment will seriously affect the service life of the meter
