33 for placing spring 21.
Figure 22 is 1 actual load schematic diagram of inspection well cover, and inspection well cover 1 is placed on inspection well cover swivel nut 7, is basement in inspection well cover swivel nut 7
Well 10, above-mentioned three clamping blocks and inspection well cover swivel nut 7 coordinate clamping, inspection shaft metal framework 8 to be placed in supercrust 9, inspection shaft
8 screw-thread fit of lid swivel nut 7 and inspection shaft metal framework can be reversed rotation inspection well cover swivel nut 7, inspection well cover when inspection well cover 1 sinks
Swivel nut 7 rises so that inspection well cover and road surface flush, and when 1 protrusion of inspection well cover, can rotate in the forward direction inspection well cover swivel nut 7, inspection well cover
Swivel nut 7 declines so that inspection well cover and road surface flush.
Specific motion process：The inspection well cover 1 normally placed is as shown in Fig. 1~5, first clamping block 1 and two second
Clamping block 3 is in the state for stretching out inspection well cover edge under the active force of spring 21, and inspection well cover 1 is fixed on road surface at this time
On, it will not there is a situation where improper disengaging road surfaces.
The inspection well cover 1 normally placed is as shown in Fig. 1~5, and first clamping block 1 and two the second clamping blocks 3 are in spring
The state for stretching out inspection well cover edge is under 21 active force, inspection well cover 1 is fixed on road surface at this time, will not occur it is non-just
The case where being often detached from road surface.
When needing to open inspection well cover 1, with reference to figure 6~11, opening tool assembly 6 is inserted into inspection well cover through-hole
In 100, when the upper plane of locating platform 61 and inspection well cover 1 is in the same plane, and the label circular hole 67 on locating platform 61
When circle center distance from inspection well cover 1 is nearest, swivel head 62 is rotated clockwise, swivel head 62 and driving cog 63 are engaged, driven
The affixed rotary shaft 64 of driving cog 63 rotates, and rotary shaft 64 and push plate 66 coordinate, direction of the push plate 66 to close 1 center of circle of inspection well cover
Mobile, the force effect that (gap between upper body and lower body is more than the height of the first clamping block) push plate 66 is moved is the
On one clamping block 2, the first clamping block 2 is also moved to the direction in 1 center of circle of inspection well cover, and the spring 21 on the first clamping block 2 is shunk, the
The inclined-plane 24 of one clamping block, 2 symmetric design acts in curved rod 5, and curved rod 5 is moved to the direction far from the first clamping block 2,
The other end of curved rod 5 acts on the surface groove 32 of the second clamping block 3, due to the inclined-plane and surface groove 32 at curved rod 5 end
Under inclined-plane mating reaction, the second clamping block 3 is moved to the direction close to the inspection well cover center of circle, while the spring on the second clamping block 3
21 it is same shrink, three clamping blocks are in the outer ring edge without departing from inspection well cover 1, and inspection well cover 1 can be opened disengaging at this time.
(swivel head can be that artificial rotation can also be motor driving rotation).
When needing to be closed inspection well cover 1, swivel head 62, under the action of the spring 21, all inspection shafts are rotated counterclockwise
Part in lid can be restored to state shown in Fig. 1-5.
Compared with the prior art, the advantages of the present invention are as follows：Make inspection well cover can by the first clamping block and the second clamping block
To be fastened in road or other facilities, and a kind of dedicated opener is provided simultaneously, make non-working person without profession
Inspection well cover can not be opened under opener, and antitheft, flood-protection function may be implemented, improve the safety of inspection well cover, it can be certainly
It is dynamic to adjust the lifting of inspection well cover by adjusting inspection shaft swivel nut.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
