Such as Fig. 3, the baffle 244 of restricted 241 winding position of drawstring is all provided with 242 both ends of rotating cylinder, baffle 244, which limits, to be stretched
The position of winding, reduces each drawstring 241 and mutually tangles because winding, and occurs too big deviation on the position of vertical direction,
The state of connecting rod 21 is caused deviation occur and can not quickly open the situation of well lid 2, drawstring 241 occurs during winding
Inevitable position offset does not influence the direction of motion of connecting rod 21, meanwhile, rubber sleeve 2421 is equipped with 242 outer wall of rotating cylinder,
The frictional force between drawstring 241 and rotating cylinder 242 is increased, drawstring 241 is also reduced in 242 surface sliding of rotating cylinder, is conducive to drawstring
Stablize 241 position on rotating cylinder 242.
Such as Fig. 2, after the adjusting work of connecting rod 21 is completed, since extension spring 3 itself has certain elastic recovery
Power, can cause the position of connecting rod 21 to change, and in the course of work of mobile well lid 2, operator can not possibly use hand always
The position of rocking bar 41 is limited, is stablized to strengthen the position of connecting rod 21, also spiral shell is extended at 4 inner end of placing groove in bull stick 24
Line is connected with locking nut 5.After adjusting work in the position for completing connecting rod 21, locking nut 5 is screwed onto and groove 11
The state of conflict, by being contradicted between 11 bottom of locking nut 5 and groove, realizes the position restriction of bull stick 24, it is achieved thereby that
The fixation of 21 position of connecting rod in 2 opening procedure of well lid.
Such as Fig. 2, the adjusting work of locking nut 5 is realized for convenience, and locking nut 5 is equipped with for rotation locking nut 5
Flank 51, operator conveniently can rotatably realize the work of rotation locking nut 5 by flank 51.
Such as Fig. 2, the cover board 7 for closing placing groove 4 is hinged with 4 notch of placing groove, cover board 7 is used for placing groove 4
Closing, reduces impurity and enters placing groove 4, while 2 surface of well lid is kept smooth, and bull stick 24 and rocking bar 41 are located in placing groove 4,
The vehicle of process is caused to hinder after reduction stretching well lid 2, vehicle is improved and passes through security.Beating for cover board 7 is realized for convenience
Push And Release closes work, opens up and be useful on the surface of cover board 7 to pull open the arc groove 71 of cover board 7, arc groove 71 is used as switch cover
The fulcrum of plate 7, facilitates operator rapidly switch cover plate 7.
Such as Fig. 2, cover board 7 is equipped with elastic rubber ring 72, elastic rubber ring 72 increase cover board 7 and 4 inner wall of placing groove it
Between frictional force, reduce vehicle and the situation for causing cover board 7 to tilt driven through on cover board 7, while improve the close of cover board 7
Feng Xing, reduces technology entry on road surface in placing groove 4, but in some cases, also inevitably has ponding and can enter and puts
The inside of groove 4 is put, occurs ponding in placing groove 4 to reduce, 4 slot bottom of placing groove also circumferentially offers some limbers 6, is used for
The water for entering placing groove 4 is discharged, reduces the use for being accumulated in and bull stick 24 being influenced in placing groove 4.
In addition, such as Fig. 2, be additionally provided with sealant layer 8 between well lid 2 and well seat 1, sealant layer 8 reduce well lid 2 with
Gap between well seat 1, strengthens the stability connected between well lid 2 and well seat 1, locking effect is advantageously ensured that, when vehicle leads to
Well lid 2 is impacted when crossing well lid 2, and sealant layer 8 has disperseed part of impact force, reach reduce vibration effect, subtract so as to
To reduce takeofing for well lid 2, safety in utilization is added, also reduces noise.
Action process
Well lid 2 is placed on well seat 1, stirring rocking bar 41 rotates bull stick 24, and drawstring 241 is wound, and stretches into connecting rod 21
In well seat 1, extension spring 3 is in extended state at this time, and the fixed block 22 in connecting rod 21 is moved down along 1 inner wall of well seat；
When well lid 2 and well seat 1 contradict, fixed block 22 is moved at 11 notch of groove, unclamps bull stick, and extension spring 3 produces
Elastic-restoring force make fixed block 22 towards 11 slot bottom direction of groove move, drawstring 241 is straightened, so that fixed block 22 is locked
In groove, by walking around, locking nut 5 locks bull stick 24, completes the fixation of well seat 1 and well lid 2；
When needing to open well lid 2, cover board 7 is opened, rotating rocker 41 winds drawstring 241 again, drives connecting rod 21
Away from 2 one end well lid of well lid, 2 central axis direction movement, fixed block 22 is removed groove 11, lock 5 fixed connecting rod of locking nut
21, reduce connecting rod 21 and the removal of well lid 2 is caused to hinder with the conflict of 1 inner wall of well seat, so as to facilitate the removal of well lid 2.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
