Anti-falling plastic inspection well
The invention relates to the technical field of plastic inspection wells, in particular to an anti-falling plastic inspection well. The anti-falling plastic inspection well comprises a shaft, check rings arranged at an upper end opening of the shaft in a surrounding mode, a bearing ring arranged above the upper end opening of the shaft and located outside the check rings, a bearing well seat attached to the upper end face of the bearing ring and a bearing well lid attached to the upper end face of the bearing well seat, and further comprises an anti-falling inner well lid; the check rings comprise the upper check ring and the lower check ring, the lower check ring comprises a sleeving portion and a supporting portion, the upper end opening of the shaft is sleeved with the sleeving portion in a surrounding mode, and the diameter of an upper end opening of the upper check ring is smaller than that of a lower end opening of the upper check ring; the inner side face of the upper check ring is provided with multiple clamping hooks or elastic parts of which the upper end faces are in an arc shape at intervals, the lower end opening of the upper check ring is connected with the supporting portion of the lower check ring, and the anti-falling inner well lid is connected with the supporting portion of the lower check ring, so that the freedom degree of the anti-falling inner well lid in the vertical direction can be limited. According to the anti-falling plastic inspection well, due to the fact that the upper check ring and the lower check ring are arranged, the freedom degree of the anti-falling inner well lid in the vertical direction is limited, the anti-falling inner well lid can support falling loads, and the safety is improved.
