Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the optical fiber distribution box comprises a box body 1 and a box cover 11;

the box body 1 comprises two plastic slide rails 7 fixed on the left side and the right side of the inner wall of the box body, notches 9 are formed in the middles of the tops of the plastic slide rails 7, circular grooves 10 are formed in the middles of the bottoms of the inner walls of the plastic slide rails 7, limiting columns 8 penetrate through the circular grooves 10, plastic pipes 14 fixed to the bottoms of the limiting columns 8 are arranged at the bottoms of the limiting columns 8, rubber rings 13 are arranged around the peripheries of the inner walls of the plastic pipes 14, the tops of the limiting columns 8 penetrate through the notches 9, and the bottoms of the limiting columns 8 extend into the plastic pipes 14 and are in tight contact with the rubber rings 13;
