Description

Electric box free of punching and convenient for installing circuit board Technical Field The utility model relates to the technical field of electric boxes, in particular to an electric box free of punching and convenient for installing a circuit board. Background The traditional electric box generally adopts a metal shell, and on-site drilling is usually required when a circuit board is installed, so that the operation is complex and the efficiency is low. More importantly, once the mounting holes of the existing electric box are formed, the positions and the specifications are fixed. When the circuit boards with different specifications are required to be installed subsequently, only drilling can be conducted again, so that the installation difficulty and the time cost are increased, the electric box body is damaged greatly, and the overall structural strength and the service life of the electric box are affected. Therefore, it is important to develop an electric box capable of conveniently installing circuit boards of different specifications without performing destructive operation on the electric box body, and the application is generated in such a background. Disclosure of utility model The utility model aims to provide a punching-free electric box capable of conveniently installing circuit boards with different specifications, so as to solve the problems that the traditional metal shell electric box needs on-site drilling, is complex in operation and low in efficiency when the circuit boards are installed, and the installation hole positions and specifications are fixed and cannot adapt to the installation requirements of the circuit boards with different specifications. The utility model provides a punching-free electric box with a circuit board convenient to install, which comprises a plastic box body, wherein an upper cover is arranged on the upper part of the plastic box body through a hinge, one side of the upper cover is detachably connected with the plastic box body through a lock catch, the circuit board is arranged in the plastic box body, an overhead upright post is integrally formed on a bottom plate in the plastic box body, and an installation hole for installing the circuit board is formed in the overhead upright post.
