Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not reality of the invention
It applies range and is confined to this.
As shown in Figures 1 to 7, a kind of dropproof manhole cover structure described in the present embodiment, including cover seat of manhole 1, circular
Cover board 2, well lid 3 and lockable mechanism 4, the cover seat of manhole 1 are equipped with L shape step, and the cover board 2 is installed on the step of cover seat of manhole 1,
It is equipped at intervals with elastic parts 5 in the cover seat of manhole 1, elastic parts 5 is corresponded on the cover board 2 and is equipped with perforation, the well lid 3 is placed
In cover seat of manhole 1 and it is located on cover board 2, the lockable mechanism 4 is mounted on the bottom surface of well lid 3；
The lockable mechanism 4 includes sheave seat 41, two or more pin shafts 42, locking rod 43, on the sheave seat 41
Corresponding locking rod 43 is provided with arcuate socket 411, one end of each locking rod 43 be in U-shape setting and with 42 axis of pin shaft
It connects, the pin shaft 42 is set in arcuate socket 411 and can the arcuately movement of hole 411；3 bottom surface of well lid corresponds to the setting of locking rod 43
There is supporting block 31, the other end activity of the locking rod 43 passes through supporting block 31, and the other end of the locking rod 43 is locked in well lid 3
The lower section of cover board 2 is firmly protruded under state, upward convex be equipped in the middle part of the sheave seat 41 twists head 412, and the well lid 3, which is equipped with, to be accommodated
Twist the accommodation groove 32 of head 412；For circular well lid 3, it is preferable that the quantity of the pin shaft 42 is three, the locking rod 43
Quantity be three, it is hexagonal that the stubborn head 412 can be set to cross section.
Preferably, elastic parts 5 is respectively provided in the periphery of cover seat of manhole 1；When installation, cover seat of manhole 1 is fixed, while by bullet
Property component 5 be packed into cover seat of manhole 1 in, then will be fixed on cover seat of manhole 1 after the good position corresponding with elastic parts 5 of cover board 2, locking machine
Structure 4 is mounted on well lid 3, and well lid 3 is then pushed down elastic parts 5 and is placed on cover board 2, then by screwing tool to stubborn
First 412 are screwed, and sheave seat 41 is driven to rotate, and the rotation of sheave seat 41 makes pin shaft 42, and arcuately hole 411 is slided, and pin shaft 42
It drives locking rod 43 protruding, until locking rod 43 protrudes into the lower section of cover board 2 and contacts with cover board 2, realizes and lock well lid 3；
And when needing to open well lid 3, reversely screw stubborn head 412, keep locking rod 43 mobile towards 2 center of cover board, until locking rod 43 with
Cover board 2 does not contact, and then by corresponding tool by 3 pull-up of well lid, takes well lid 3 away, the accommodation groove 32 of well lid 3 can with it is corresponding
Tool cooperates 3 pull-up of well lid, or the pulling eye for cooperating with corresponding tool is symmetrical arranged on well lid 3；And taking well away
While lid 3, elastic parts 5 in an unloaded situation, is popped up by the effect of elastic force, so as to remind passerby, is prevented
Only under people's back drop, risk is reduced, and by setting elastic parts 5, when carrying out 3 replacement operation of well lid, at lockable mechanism 4
Under opening state, elastic parts 5 can provide upward elastic force, the more conducively pull-up of well lid 3, be conveniently replaceable well lid 3.
The latching and opening that lockable mechanism 4 realizes well lid 3 is arranged in the present embodiment, and well lid 3 is effectively prevent to be tampered or well
Lid 3 loosens, while can prevent well lid 3 from being washed open under rainstorm weather by water flow；And well lid is washed open in the replacement of progress well lid 3 or water flow
When 3, the elastic parts 5 on cover seat of manhole 1 can pop up automatically, reach warning effect, can effectively remind passerby, avoid passerby not
Under careful back drop, risk is reduced.
Further, the cover seat of manhole 1 is equipped with mounting hole, and the elastic parts 5 is set in mounting hole；The elastic parts
5 include spring 51 and elevating lever 52, and one end and the cover seat of manhole 1 of the spring 51 abut against, the other end of the spring 51 and lifting
One end of bar 52 abuts against, and the other end of the elevating lever 52 is in the state of no well lid 3 to upper stretching after perforation；Specifically
Ground makes elevating lever 52 pass through cover board 2 and pops up, energy when taking well lid 3 away or without under 3 state of well lid, spring 51 restores to the original state
Passerby is effectively reminded, is avoided under passerby's back drop, risk is reduced.
It further include dustproof cover 6 further on the basis of based on the above embodiment, the dustproof cover 6 closes accommodating for covering
Slot 32；Specifically, cover seat of manhole 1 is installed, after the latching of well lid 3, the lid of dustproof cover 6 is closed on accommodation groove 32, can effectively be avoided
Dust or other foreign matters are fallen into accommodation groove 32, more reasonable structure.
For rectangular well lid 3, it is preferable that the quantity of the locking rod 43 four, the quantity of corresponding pin shaft 42 are 4
It is a, and the four sides setting of the corresponding square well cover 3 of locking rod 43.The present embodiment can be correspondingly arranged according to the different shape of well lid 3
The locking rod 43 and pin shaft 42 of different number, to reach preferably locking well lid 3.
The above is only a preferred embodiment of the invention, therefore all according to structure described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, in the protection scope of present patent application.
