AI Technical Summary

Technical Problem

然而上述装置在使用时存在以下缺陷，在施工现场，地面往往存在高低落差，相邻两个防护装置的安装面会形成高度差，导致一侧装置的配合板与另一侧装置的连接板不在同一水平面上，插入块无法顺利插入插入槽内，进而无法完成后续滑动插接块对插入块的限位锁定，这不仅会导致防护装置拼接失败，无法形成连续完整的防护围栏，留下安全防护盲区；若强行拼接，还可能造成插入块、滑动插接块等部件变形损坏

Benefits of technology

[0018] Compared with the prior art, this utility model has at least the following advantages: In use, the protective body is first fixed to the ground around the pit by the support components. According to the height difference between adjacent protective devices, the first connecting block is rotated and the telescopic component is stretched or contracted, so that one end of the telescopic component extends into the corresponding insertion slot of the first connecting block. The connection between the two is completed by the locking component, realizing the splicing of adjacent protective devices. The protective body and the connecting plate are both independently fixed by the support components. Combined with the rotation adjustment of the first connecting block and the length adaptation of the telescopic component, the installation deviation caused by the ground height difference can be flexibly offset, ensuring the continuity and integrity of the protective structure.
