Description

A kind of 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.

A kind of drain cover with overturning catch, includes the lid equipped with fence hole, and the lid both sides are equipped with pedestal, The lid can move up and down in the pedestal, and vertical reset spring is equipped between the lid and pedestal lower edge；The lid Downside be equipped with overturning catch corresponding with fence hole, it is described overturning catch one end be connected on torsion shaft, the overturning The both ends of axis are erected on the fixed block in pedestal lower edge, and the both ends of torsion shaft are fixed with gear；Under the lid Side is additionally provided with cavity, and the exit of the cavity is fixed with nut, leading screw, the other end of the leading screw are equipped in the nut Rotation is set in the mounting base in pedestal lower edge, and worm screw is fixed on the leading screw, and the screw thread on the worm screw coordinates with gear；Institute State drives nut to move down when lid moves down, and so that leading screw is rotated and worm screw is driven to rotate, gear is made to rotate and overturning catch is made to turn over The downside in fence hole is blocked after turning.

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 Nut also moves down therewith, so that leading screw therein is rotated by screw-thread fit in folding process, and leading screw rotation drives worm screw thereon Rotation, and then make to rotate with the gear that worm screw coordinates, torsion shaft rotation is driven, so that overturning catch is rotated and blocks fence hole, is risen To the effect of leakproof, small articles are not fallen out in sewer.After the foot of pedestrian leaves, lid is under the effect of vertical reset spring It moves up, while nut moves up therewith, leading screw, worm gear, gear rotate backward, and overturning catch opens fence hole after resetting not to be influenced just Normal draining.

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 leading screw, which is located at one end in cavity, is equipped with limited block, prevent it from deviating from nut.

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 with overturning catch, includes the lid 1 equipped with fence hole 11, the lid 1 both sides of body are equipped with pedestal 2, and the lid 1 can move up and down in the pedestal 2, is equipped between 22 under the lid 1 and pedestal Vertical reset spring 121；The downside of the lid 1 is equipped with overturning catch 3 corresponding with fence hole 11, the overturning catch 3 One end be connected on torsion shaft 31, the both ends of the torsion shaft 31 are erected under pedestal on the fixed block 32 on 22, And the both ends of torsion shaft 31 are fixed with gear 33；The downside of the lid 1 is additionally provided with cavity 12, and the exit of the cavity 12 is solid Surely there is nut 13, leading screw 24 is equipped in the nut 13, the other end rotation of the leading screw 24 is set under pedestal along 22 In mounting base 23, worm screw 25 is fixed on the leading screw 24, the screw thread on the worm screw 25 coordinates with gear 33；Under the lid 1 It drives nut 13 to move down when shifting, and so that leading screw 24 is rotated and drive worm screw 25 to rotate, gear 33 is made to rotate and overturning catch 3 is made to turn over The downside in fence hole 11 is blocked after turning.

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 leading screw 24 is located at one end in cavity 12 and is equipped with limited block 241；The lid 1 is evenly arranged with five Fence hole 11, the downside of the lid 1 are equipped with five overturning catch 3, when lid 1 does not stress described in five overturning catch 3 at 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 nut 13 also moves down therewith during being somebody's turn to do, and makes silk therein by screw-thread fit in folding process Thick stick 24 rotates, and the rotation of leading screw 24 drives worm screw 25 thereon to rotate, and then makes to rotate with the gear 33 that worm screw 25 coordinates, and drive is turned over Shaft 31 rotates, and so that overturning catch 3 is rotated and blocks fence hole 11, plays the effect of leakproof, small articles do not fall out lower water In road.After the foot of pedestrian leaves, lid 1 moves up under the effect of vertical reset spring 121, while nut 13 moves up therewith, leading screw 24, worm gear 25, gear 33 rotate backward, and overturning catch 3 opens fence hole 11 after resetting not to be influenced normally to drain, very square Just.

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.
