TECHNICAL FIELD
[0001] The utility model relates to an electric meter box technical field, concretely is an electric meter box ventilation structure. BACKGROUND
[0002] The electric meter box is the equipment for the electric meter storage, and the material for manufacturing the low-voltage cable branch box body is a resin-based composite material. The main components of the box body are ABS engineering plastics, polycarbonate transparent PC material, DMC and SMC, which are formed by injection molding and pressing. This composite material is composed of two parts: the matrix - polyester resin; and the reinforcing material (PC and SMC). Therefore, it is also called transparent PC material and fiber-reinforced polyester material. Transparent PC material and fiber-reinforced unsaturated polyester are a kind of composite material with unsaturated polyester resin as the matrix. These two materials have the characteristics of insolubility, flame retardancy and recyclability. The latter material has the disadvantages of non-melting and non-recyclability, and its physical structure is a three-dimensional network structure. These four materials have become a high-performance engineering material through functional filler modification and special fiber reinforcement.
[0003] During the use of the electric meter box, the outdoor environment is relatively complex, and the electric meter inside the electric meter box needs to be cooled. Therefore, a ventilation groove is formed on the outside of the shell. In order to prevent rain, a triangular structure with an open bottom is formed. This structure can effectively prevent rainwater from entering, but the ventilation capacity is limited, which affects the efficiency of temperature exchange between the inside and outside. Therefore, we propose an electric meter box ventilation structure. UTILITY MODEL CONTENT
