The sealing cover is arranged on the box body, and a plurality of wiring holes are arranged on the box body. The optical splitter is installed in the box body; the optical splitter can be protected by the box body. The inventor believes that there are the following problems in its use. Since it is only a box body, when the optical splitter is installed outdoors, it needs to be installed at different heights according to the cable distribution on site. Obviously, the above-mentioned protection device in the prior art does not have the function of adjusting the installation height of the optical splitter, resulting in inconvenient use and poor practicability. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides an outdoor optical splitter protection device that can adjust the installation height of the optical splitter as needed, is convenient to use, has low limitations, and high practicability.

The multiple bolts tightly fix the two sets of sliding blocks to the two sets of slide rails respectively. The connecting plate is fixedly installed on the two sets of sliding blocks, and the protection box is fixedly installed on the connecting plate. When adjusting the height of the protection box, first rotate the bolts on the two sets of sliding blocks so that the bolts are disengaged from contact with the slide rails. Then, by sliding the two sets of sliding blocks, the connecting plate drives the protection box to adjust the height, and the protection box drives the optical splitter to adjust the height until the optical splitter is adjusted to a suitable installation height. Then, tighten the multiple bolts so that the multiple bolts are respectively tightly fixed to the tops of the two sets of slide rails to fix the heights of the two sets of sliding blocks. This facilitates the adjustment of the height of the optical splitter and improves the convenience.
