[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an anti-sinking adjustable manhole cover, comprising a manhole frame 1, the inner wall of the manhole frame 1 is symmetrically provided with notches 17, a single notch 17 is provided inside a fixed shaft 19, the outer wall of the fixed shaft 19 is provided with a manhole cover 2, a connecting bolt 4 is provided on the top of the manhole cover 2, one end of the connecting bolt 4 movably passes through the manhole cover 2 and is connected with a pointed cone 5, a limiting ring 6 is provided on the inner side of the manhole frame 1, a plurality of connecting frames 7 are evenly distributed on the outer wall of the limiting ring 6, one end of the connecting frame 7 is fixedly connected to the manhole frame 1, a plurality of movable rods 8 are movably connected to the inner wall of the limiting ring 6, one end of the movable rod 8 is fixedly connected to an arc block 10, the other end of the movable rod 8 is fixedly connected to a clamping block 11, and a spring 9 is sleeved on the outer side of the movable rod 8 between the limiting ring 6 and the arc block 10.

[0024] In this embodiment, by screwing the connecting bolt 4, the pointed cone 5 is pushed down, causing the multiple arc blocks 10 to separate, and the spring 9 is squeezed to shrink. At the same time, the arc block 10 separates and pushes the movable rod 8 to slide, so that the blocking block 11 fits on the outside of the mounting bolt 14, thereby achieving the goal of completely fixing the manhole cover 2 on the inside of the manhole frame 1 to prevent it from shaking or shifting due to force, effectively improving its stability, meeting the use requirements, and avoiding the occurrence of safety accidents. At the same time, the rebound force of 9 will push 10 to clamp and fix 4, which in turn provides support force for 2, so that the force on 2 is dispersed to the surroundings, thereby effectively reducing the settlement of the manhole cover and avoiding uneven road surface and safety hazards caused by the sinking of the manhole cover.

[0025] Example 2

[0026] like Figure 1-Figure 5 As shown, a plurality of supporting blocks 12 are fixedly installed on the inner wall of the manhole frame 1, a bracket 13 is arranged at the bottom of the manhole frame 1, the bracket 13 is fixedly connected to the supporting block 12 by mounting bolts 14, a plurality of through holes 15 are penetrated through the surface of the bracket 13, a first mounting screw hole 3 is penetrated through the top of the manhole cover 2, a connecting bolt 4 is installed on the inner side of the first mounting screw hole 3, a plurality of second mounting screw holes 16 are penetrated through the top of the manhole frame 1, a fixing block 18 is fixedly connected to the outer wall of the manhole cover 2, an octagonal frame 20 is fixedly installed at the bottom of the manhole cover 2, a plurality of stiffening ribs 21 are evenly distributed on the outer wall of the octagonal frame 20, a plurality of drainage outlets 22 are penetrated through the top of the manhole cover 2, and the manhole cover 2 is arranged on the inner side of the manhole frame 1.

[0027] In this embodiment, the supporting block 12 can support the manhole cover 2 so that the force on the manhole cover 2 can be evenly dispersed, and the bracket 13 can be fixed to the bottom of the manhole frame 1 by screwing the mounting bolts 14, and the mounting bolts 14 can be prevented from falling off the supporting block 12 due to the squeezing force transmitted by the clamping block 11. The through-hole 15 can be used to perform drainage and exhaust work normally, thereby improving the safety of the manhole during use and preventing maintenance personnel or pedestrians from falling into the well and getting injured. By inserting the bolt into the second mounting screw hole 16, the manhole frame 1 can be completely fixed to the road surface, and a crowbar can be inserted into the single slot 17 and the fixing block 18 can be pried to rotate the manhole cover 2 on the fixed axis 19 to open it. The octagonal frame 20 and the stiffening rib plate 21 can further improve the strength of the manhole cover 2 and extend its service life.

[0028] Working principle of this embodiment: When in use, first screw the mounting bolt 14 to connect it with the supporting block 12, fix the bracket 13 to the bottom of the manhole frame 1, then insert the high-strength bolt into the second mounting screw hole 16 and screw it, fix the manhole frame 1 as a whole on the road surface, then push the manhole cover 2 to rotate the manhole cover 2 on the fixed shaft 19 to close the manhole, then insert the connecting bolt 4 into the first mounting screw hole 3 and screw it, so that the connecting bolt 4 pushes the pointed cone 5 downward, causing the multiple arc blocks 10 to separate, and the spring 9 is squeezed. Rapid contraction and separation of multiple arc blocks 10 will push the movable rod 8 to slide on the limit ring 6, thereby pushing the blocking block 11 to fit and get stuck on the outside of the movable rod 8. Finally, when the manhole needs to be opened for inspection, the connecting bolt 4 should be turned to remove it. At the same time, the spring 9 quickly rebounds, pushing the multiple arc blocks 10 gradually close together, releasing the squeezing of the blocking block 11 on the mounting bolt 14, and then use a crowbar to insert it into a single slot 17 to pry the fixed block 18, so that the manhole cover 2 is forced to rotate and open, thereby completing the use of the anti-subsidence adjustable manhole cover.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
