Abstract

Drain cover with overturning catch, includes the lid equipped with fence hole, and the lid both sides are equipped with pedestal, and the lid can move up and down in the pedestal, and vertical reset spring is equipped between the lid and pedestal lower edge；The downside of the lid is equipped with overturning catch corresponding with fence hole, one end of the overturning catch is connected on torsion shaft, the both ends of the torsion shaft are erected on the fixed block in pedestal lower edge, and the both ends of torsion shaft are fixed with gear, the lower surface of the lid is equipped with convex block, and the side of convex block is equipped with the rack engaged with the gear；It drives convex block to move down when the lid moves down, and gear is made to rotate, the downside in fence hole is blocked after so that overturning catch is overturn.In pedestrian's walking process, the fence hole of the drain cover of pedestrian underfooting can be automatically closed in the present invention, prevent small articles from accidentally falling in sewer；And after pedestrian passes by, fence hole can automatically open, and not influence normally to drain.

Description

Drain cover with overturning catch

Technical field

The invention belongs to municipal articles for use fields, and in particular to a kind of drain cover with overturning catch.

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 cover with overturning catch, can by Automatically catch is dug when pressure and blocks fence hole, prevents article from falling in sewer.

The invention is realized by the following technical scheme.

Drain cover with overturning catch, includes the lid equipped with fence hole, and the lid both sides are equipped with pedestal, described Lid can move up and down in the pedestal, and vertical reset spring is equipped between the lid and pedestal lower edge；Under the lid Side is equipped with overturning catch corresponding with fence hole, and one end of the overturning catch is connected on torsion shaft, the torsion shaft Both ends are erected on the fixed block in pedestal lower edge, and the both ends of torsion shaft are fixed with gear, the lower surface of the lid Equipped with convex block, the side of convex block is equipped with the rack engaged with the gear；It drives convex block to move down when the lid moves down, and makes tooth Wheel rotation, blocks the downside in fence hole 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 Convex block also moves down therewith, the gear rotation that rack drives thereon engage so that torsion shaft rotates therewith, and drives thereon Overturning catch rotation so that overturning catch is blocked fence hole, play the effect of leakproof, small articles are not fallen out in sewer.Row After the foot of people leaves, lid moves up under the effect of vertical reset spring, while convex block moves up therewith, and rack moves up and keeps gear anti- To rotation, overturning catch 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, 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. 7, there is the drain cover of overturning catch, include the lid 1 equipped with fence hole 11,1 liang of the lid Side is equipped with pedestal 2, and the lid 1 can move up and down in the pedestal 2, and the lid 1 is vertical with being equipped between 22 under pedestal Resetting spring 121；The downside of the lid 1 is equipped with overturning catch 3 corresponding with fence hole 11, described to overturn the one of catch 3 End is connected on torsion shaft 31, and the both ends of the torsion shaft 31 are erected under pedestal on the fixed block 32 on 22, and are turned over The both ends of shaft 31 are fixed with gear 33, and the lower surface of the lid 1 is equipped with convex block 12, and the side of convex block 12 is equipped with and the tooth The rack 13 of 33 engagement of wheel；It drives convex block 12 to move down when the lid 1 moves down, and gear 33 is made to rotate, overturning catch 3 is made to overturn The downside in fence hole 11 is blocked afterwards.

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；The lid 1 is evenly arranged with five fence holes 11, and the downside of the lid 1 is equipped with five overturning catch 3, Five overturning catch 3 described in when lid 1 does not stress are 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 convex block 12 also moves down therewith during being somebody's turn to do, and rack 13 thereon drives the gear 33 engaged Rotation so that torsion shaft 31 rotates therewith, and drives the rotation of overturning catch 3 thereon that overturning catch 3 is made to block fence hole 11, rises To the effect of leakproof, small articles are not fallen out in sewer.After the foot of pedestrian leaves, lid 1 is acted in vertical reset spring Under move up, while convex block 12 moves up therewith, and rack 13 moves up and gear 33 is made to rotate backward, and overturning catch 3 opens grid after resetting Column hole 11 does not influence normally to drain, 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.
