It is U-clamp head, the upper bare terminal end of the U-clamp head is installed on the upper surface of the steel plate, and the upper bare terminal end of the U-clamp head is opened
Screw is provided with, is used to earth stud is installed and the U-clamp head is fixed on the steel plate.
It is preferred that the U-clamp headgear is provided with chuck reinforcement, to prevent the U-clamp head because of external force opening.
The effect of closing connector of the present utility model is that the fixed guard ring and the column are surrounded into isolation sky
Between, to prevent people from dropping.Meanwhile, closing connector of the present utility model can adjust length according to actual manhole size, so that
The demand of different manholes is adapted to, it is preferred that the closing connector is safety chains.
It is preferred that the closing connector is provided with annulus with the column junction, facilitate consolidating for the closing connector
Fixed and adjustment length.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, obtain final product the utility model it is each compared with
Good example.
Positive effect of the present utility model is：
1st, block manhole guard ring of the present utility model can be adjusted according to the size of manhole, strong applicability.
2nd, block manhole guard ring installation difficulty of the present utility model is small, and damage is not resulted in Ship Structure during dismounting
Evil.
