Description

A kind of drain cover

Technical field

The invention belongs to municipal articles for use fields, and in particular to a kind of drain cover, having prevents object from falling to sewer In function.

Background technology

With the quickening of urbanization process, urban infrastructure is increasingly paid close attention to by civic, and one in urban construction The small details of a little hommizations, is also increasingly welcome by civic.

Currently, many road both sides are additionally provided with the sewer for rainwater, sewage discharge, grid are stamped on these sewers The drain cover of column, rainwater can be entered by fence through-hole in sewer when raining, and be used for road drainage.But this kind of form Drain cover it occur frequently that article falls to the generation of the situation in sewer, such as pedestrian is when roadside is walked, mobile phone, key When spoon, wallet and other items are fallen from hand, enter in sewer across fence hole, this is to generally require to lift drain cover by object Product take out, and when having ponding in sewer, can also cause the damage of mobile phone, cumbersome.

Therefore, the present invention is studied on this direction, has developed a kind of sewer falling function with anti-object Lid.

Invention content

For deficiency in the prior art, the present invention provides a kind of drain covers, can automatically be dug when being under pressure Catch blocks fence hole, prevents article from falling in sewer.

The invention is realized by the following technical scheme.

A kind of drain cover includes the lid equipped with fence hole, and the lid both sides are equipped with pedestal, and the lid can be at this It moves up and down in pedestal, vertical reset spring is equipped between the lid and pedestal lower edge；The downside of the lid is equipped with and grid One end of the corresponding overturning catch in column hole, the overturning catch is connected on torsion shaft, and the both ends of the torsion shaft are erected at On the fixed block in pedestal lower edge, and the both ends of torsion shaft are fixed with wheel disc；It is additionally provided with fixed link on the downside of the lid, The end of the fixed link is stretched into the limit chamber in the pedestal in pedestal lower edge, and the end of the fixed link is articulated with company The other end of bar, the connecting rod is articulated on wheel disc；It drives fixed link to move down when the lid moves down, and makes connecting rod that wheel disc be pushed to turn It is dynamic, and the downside in fence hole is blocked after so that overturning catch is overturn.

Drain cover in the prior art is simple in structure, and without drip-preventing function, article is easy to fall in sewer.This hair In bright, after when pedestrian walks, foot steps down on lid, lid forced compression vertical reset spring simultaneously slightly moves down, during being somebody's turn to do Fixed link moves down therewith, and the end of fixed link moves downward in limit chamber in folding process, and pushes wheel disc to turn by connecting rod It is dynamic, so that overturning catch is rotated and block fence hole, plays the effect of leakproof, small articles are not fallen out in sewer.Pedestrian's After foot leaves, lid moves up under the effect of vertical reset spring, while fixed link moves up therewith, and wheel disc rotates backward, overturning gear Piece opens fence hole after resetting not to be influenced normally to drain.

Preferably, the fixed block is equipped with slot or through-hole, the both ends of the torsion shaft are placed in the slot or through-hole In, play the role of fixed, limit torsion shaft.

Preferably, being equipped with resetting spring in the limit chamber, play reset role.

Preferably, the lid is evenly arranged with five fence holes, the downside of the lid is equipped with five overturning catch, Five overturning catch described in when lid does not stress are in vertical state.

Compared with prior art, the invention has the advantages that：Pedestrian can be automatically closed in pedestrian's walking process The fence hole of the drain cover of underfooting, prevents small articles from accidentally falling in sewer；And after pedestrian passes by, fence hole energy It automatically opens, does not influence normally to drain.

Specific implementation mode

Below in conjunction with the accompanying drawings with specific implementation mode, the invention will be further described.

See Fig. 1 to Fig. 8, a kind of drain cover includes the lid 1 equipped with fence hole 11, and 1 both sides of the lid are equipped with pedestal 2, the lid 1 can move up and down in the pedestal 2, be equipped with vertical reset spring under the lid 1 and pedestal between 22 121；The downside of the lid 1 is equipped with overturning catch 3 corresponding with fence hole 11, and one end of the overturning catch 3 is connected to On torsion shaft 31, the both ends of the torsion shaft 31 are erected under pedestal on the fixed block 32 on 22, and torsion shaft 31 Both ends are fixed with wheel disc 33；The downside of the lid 1 is additionally provided with fixed link 13, and the end of the fixed link 13 is stretched into set on pedestal In limit chamber 34 in the lower pedestal 36 on 22, the end of the fixed link 13 is equipped with sliding block 14, the company of being articulated on sliding block 14 The other end of bar 35, the connecting rod 35 is articulated on wheel disc 33；It drives fixed link 13 to move down when the lid 1 moves down, and makes connecting rod 35 push wheel disc 33 to rotate, and the downside in fence hole 11 is blocked after so that overturning catch 3 is overturn.

In present embodiment, the fixed block 32 is equipped with slot or through-hole, and the both ends of the torsion shaft 31 are placed in the slot In hole or through-hole；Resetting spring 341 is equipped in the limit chamber 34；The lid 1 is evenly arranged with five fence holes 11, described The downside of lid 1 be equipped with five overturning catch 3, when lid 1 does not stress described in five overturning catch 3 be in vertical state.

Drain cover in the present invention, after when pedestrian walks, foot steps down on lid 1,1 forced compression of lid is vertically multiple Position spring 121 simultaneously slightly moves down, and fixed link 13 moves down therewith during being somebody's turn to do, and the end of fixed link 13 is in limit chamber in folding process It is moved downward in 34, and pushes wheel disc 33 to rotate by connecting rod 35, overturning catch 3 is made to rotate and block fence hole 11, played anti- The effect of leakage, small articles are not fallen out in sewer.After the foot of pedestrian leaves, lid is under the effect of vertical reset spring 121 It moves up, while fixed link 13 moves up therewith, wheel disc 33 rotates backward, and overturning catch 3 opens fence hole 11 after resetting not to be influenced just Normal draining, it is very convenient.

Protection scope of the present invention includes but not limited to embodiment of above, and protection scope of the present invention is with claims Subject to, any replacement being readily apparent that those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's Protection domain.
