A limit slide bar 6 is installed, and a limit sleeve 7 is symmetrically installed on the bottom inner wall of the circular cover plate 1, and multiple groups of limit sleeves 7 are located on the outside of multiple groups of dampers 3. The limit slide grooves 8 are symmetrically opened on both sides of the limit sleeve 7, and the limit slide grooves 8 are movably connected with the limit slide bar 6. A shock-absorbing torsion spring 9 is installed on the bottom inner wall of the limit sleeve 7, and the other end of the shock-absorbing torsion spring 9 is connected to the pressure block 5. A sinking ring 10 is installed on the top outer side of the circular cover plate 1, and the sinking ring 10 is located below the convex ring 2. The circular cover plate 1 provides an installation position for the convex ring 2 and the shock-absorbing assembly. The convex ring 2 can be engaged with the sinking ring 10 on the buffer cover 4 to prevent the buffer cover 4 from separating from the circular cover plate 1. The damper 3 can reduce the vibration amplitude by dissipating vibration energy, thereby reducing damage to the structure and noise. The damper 3 also provides an installation position for the buffer cover 4. The buffer cover 4 provides an installation position for the pressure block 5. The pressure block 5 provides an installation position for the limit slide bar 6. The limiting slide bar 6 and the limiting slide groove 8 cooperate with each other to limit the movement direction of the pressure block 5. The limiting sleeve 7 provides an opening position for the limiting slide groove 8 and provides an installation position for the shock-absorbing torsion spring 9. The shock-absorbing torsion spring 9 absorbs the energy of vibration based on elastic deformation. When the vehicle passes through the manhole cover, the pressure acts on the buffer cover 4, the pressure block 5 at the bottom of the buffer cover 4 slides inside the limiting sleeve 7, and the limiting slide bar 6 slides inside the limiting slide groove 8 to avoid the displacement of the pressure block 5. The damper 3 provides movement resistance and dissipates the energy of vibration. The shock-absorbing torsion spring 9 undergoes elastic deformation and absorbs some of the larger vibrations. The cooperation between the damper 3 and the shock-absorbing torsion spring 9 can absorb the vibration caused by the car contacting the manhole cover, so as to reduce the vibration of the vehicle as much as possible and reduce noise.

[0025] Embodiment 2: Figure 1-Figure 4As shown, a drain port 11 is provided at the top center of the buffer cover 4, a filter screen 12 is installed on the inner side of the drain port 11, an anti-skid pattern 15 is installed on the top of the buffer cover 4, and the anti-skid pattern 15 is located on the outer side of the drain port 11, an inverted cone hole 13 is provided through the bottom inner wall of the circular cover plate 1, and a limiting cylinder 14 is connected to the bottom of the circular cover plate 1. The circular cover plate 1 provides an installation position for the drain port 11 and the limiting cylinder 14. The drain port 11 can make the manhole cover have a sufficient drainage effect. The filter screen 12 can effectively prevent large impurities on the road surface from entering the inside of the circular cover plate 1. The anti-skid pattern 15 can prevent pedestrians from slipping and falling when stepping on the manhole cover. The inverted cone hole 13 can allow the filtered sewage to be discharged from the manhole cover, and the inclined design can guide the sewage to flow out. When it rains, rainwater from outside may flow with garbage on the road. When passing through the manhole cover, larger garbage will remain on the filter screen 12, and rainwater will flow into the manhole cover from the drain port 11 and finally flow into the sewer shaft along the inverted cone hole 13.

[0026] Embodiment 3: A well ring seat 16 is installed on the outer side of the circular cover plate 1, and the inner side of the well ring seat 16 contacts the limiting cylinder 14. The outer side of the limiting cylinder 14 is symmetrically provided with a mounting groove 17. The inner wall of one side of the mounting groove 17 is connected with a limiting torsion spring 18. One end of the limiting torsion spring 18 is connected with a clamping block 19. The inner side of the well ring seat 16 is symmetrically provided with a clamping groove 20, and the clamping groove 20 matches the clamping block 19. The circular cover plate 1 provides an installation position for the well ring seat 16. The limiting cylinder 14 matches the cellar of the sewer pipe used by the well cover, effectively preventing the well cover from flipping due to uneven force. The limiting cylinder 14 provides an opening position for the mounting groove 17. The well ring seat 16 provides an opening position for the clamping groove 20. The mounting groove 17 provides an installation position for the limiting torsion spring 18, and the shape of the mounting groove 17 prevents the limiting torsion spring 18 from deflecting. The limiting torsion spring 18 provides an installation position for the clamping block 19. The limiting torsion spring 18 and the clamping block 19 cooperate with the engaging groove 20 to limit the position of the limiting cylinder 14 on the well ring seat 16. When the well cover is installed on the well ring seat 16, the clamping block 19 on the limiting cylinder 14 is pressed into the inside of the installation groove 17, the limiting torsion spring 18 is compressed, and the limiting cylinder 14 is slid downward to be installed on the well ring seat 16. After the well cover is installed, the installation groove 17 on the limiting cylinder 14 corresponds to the engaging groove 20. At this time, the clamping block 19 is not limited by external force, and the limiting torsion spring 18 is reset, so that the clamping block 19 enters the inside of the engaging groove 20, restricting and fixing the well cover to prevent the well cover from being washed away by the water in the well.

[0027] Working principle: Before using the anti-flip manhole cover, you should first check whether there are any problems that affect the use of the anti-flip manhole cover. First, place the anti-flip manhole cover at the position where it needs to be used. When installing the manhole cover on the manhole ring seat 16, press the block 19 on the limiting cylinder 14 into the installation groove 17, and the limiting torsion spring 18 is compressed. Slide the limiting cylinder 14 downward and install it on the manhole ring seat 16. After the manhole cover is installed, the installation groove 17 on the limiting cylinder 14 corresponds to the engaging groove 20. At this time, the block 19 is not restricted by external force, and the limiting torsion spring 18 is reset, so that the block 19 enters the inside of the engaging groove 20, restricting and fixing the manhole cover to prevent the water in the well from washing away the manhole cover. When a vehicle passes through the manhole cover, pressure acts on the buffer cover 4, and the pressure block 5 at the bottom of the buffer cover 4 slides inside the limiting sleeve 7, and the limiting slide bar 6 slides inside the limiting slide groove 8 to avoid the displacement of the pressure block 5. The damper 3 provides movement resistance and dissipates the energy of vibration. The shock-absorbing torsion spring 9 undergoes elastic deformation and absorbs some of the larger vibrations. The cooperation between the damper 3 and the shock-absorbing torsion spring 9 can absorb the vibration generated by the car contacting the manhole cover when driving, so as to reduce the vibration of the vehicle as much as possible and reduce noise.
