Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in the accompanying

drawings

1 and 3, the shockproof well lid comprises a well lid 2 and a well base 4, wherein the well lid 2 is located above the well base 4, an installation groove 3 is formed in the bottom of the well lid 2, a shockproof pad 5 is fixedly installed in the installation groove 3, and the bottom of the shockproof pad 5 is attached to the top of the well base 4. The top of the well lid 2 is provided with two slots 7, and the well lid 2 is provided with a bolt 1 capable of penetrating into the two slots 7. Well

lid

2 and 4 mounting structure of well seat can be prior art hinged joint, make more convenient bolt 1 aim at the screw hole on the movable plate 6 when the installation well lid.

As shown in fig. 1 and 2, fixing grooves 9 are respectively formed in inner walls of two sides of the well seat 4, moving plates 6 are respectively installed in the two fixing grooves 9, screw holes are respectively formed in the tail ends of the tops of the two moving plates 6, the screw holes and the two bolts 1 are located on the same axis, and through holes are respectively formed in the head ends of the tops of the two moving plates 6. The well seat 4 is provided with screws 8 capable of penetrating into the two fixing grooves 9, and the two screws 8 penetrate through the two fixing grooves 9 in through holes in the two moving plates 6, so that the two moving plates 6 are fixed on the two screws 8.
