Description

A kind of drain cover that anti-object is fallen

Technical field

The invention belongs to municipal articles fields, and in particular to a kind of drain cover that function is fallen with anti-object.

Background technique

With the quickening of urbanization process, urban infrastructure is increasingly paid close attention to by civic, 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 in sewer by fence through-hole when raining, and be used for road drainage.But this kind of form Drain cover it occur frequently that article falls to the situation in sewer, such as pedestrian is when roadside is walked, mobile phone, key, money Packet and other items enters in sewer across fence hole when falling from hand, at this moment generally requires to lift drain cover and takes article Out, when having ponding in sewer, the damage of mobile phone can also be caused, it is cumbersome.

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

Summary of the invention

Aiming at the shortcomings in the prior art, the present invention provides a kind of drain cover that function is fallen with anti-object, energy Fence hole is automatically closed when being under pressure, prevents article from falling in sewer.

The invention is realized by the following technical scheme.

A kind of drain cover that anti-object is fallen, the lid including being equipped with fence hole, the lid two sides are equipped with pedestal, institute Stating 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 is equipped with leakage prevention sheet corresponding with fence hole, and the two sides of the leakage prevention sheet are connected with sideslip substrate, and the sideslip substrate is stretched Enter in the gap between pedestal lower edge and lid, equipped with gear set, the side of the gear set and set on gear cavity in the gap The first rack gear engagement on inner wall, the other side of gear set are engaged with the second rack gear for being set to sideslip upper surface of base plate；The lid The first rack gear moves down and acts on gear set when body moves down, and the gear set rotates and acts on the second rack gear, and makes sideslip base Plate moves horizontally, and leakage prevention sheet is made to be moved to the downside in fence hole.

Drain cover structure in the prior art is simple, and without drip-preventing function, article is easy to fall in sewer.This hair In bright, after when pedestrian walks, foot is stepped down on lid, lid forced compression vertical reset spring is simultaneously slightly moved down, during being somebody's turn to do First rack gear moves down, and rotates the gear engaged, and gear set is started to work, and power is transferred to the engaged with gear set It on two rack gears, and then moves together sideslip substrate together with leakage prevention sheet, so that leakage prevention sheet is moved to the lower section in fence hole, play leakproof Effect, small articles do not fall out in sewer.After the foot of pedestrian leaves, lid moves up under the effect of vertical reset spring, The first rack gear moves up simultaneously, and rotates backward the gear engaged, and then reset sideslip substrate together with leakage prevention sheet, Fence hole is opened again, does not influence normally to drain.

Preferably, roller or ball are equipped between the sideslip base lower surface and the upper surface of pedestal lower edge, it can be with The resistance in sideslip substrate translation motion is reduced, movement is more smooth.

Preferably, the lid is evenly arranged with five fence holes, the downside of the lid is equipped with five leakage prevention sheets, lid Five leakage prevention sheets described in when body does not stress are arranged in a staggered manner with five fence holes.

Compared with prior art, the invention has the following advantages: 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 embodiment

With reference to the accompanying drawing with specific embodiment, the invention will be further described.

See Fig. 1 to Fig. 8, a kind of drain cover that anti-object is fallen, the lid 1 including being equipped with fence hole 11, the lid 1 Two sides are equipped with pedestal 2, and the lid 1 can move up and down in the pedestal 2, are equipped with and hang down between 22 under the lid 1 and pedestal Straight reset spring 121；The downside of the lid 1 is equipped with leakage prevention sheet 3 corresponding with fence hole 11, the two sides of the leakage prevention sheet 3 It is connected with sideslip substrate 31, the sideslip substrate 31 protrudes into the gap under pedestal between 22 and lid 1, is equipped in the gap The gear set 322 being fixed on pedestal side wall, the side of the gear set 322 and the first rack gear being set on 12 inner wall of gear cavity 122 engagements, the other side of gear set 322 are engaged with the second rack gear 32 for being set to 31 upper surface of sideslip substrate；The lid 1 moves down When the first rack gear 122 move down and act on gear set 322, the gear set 322, which rotates, simultaneously acts on the second rack gear 32, and makes side Sliding substrate 31 moves horizontally, and leakage prevention sheet 3 is made to be moved to the downside in fence hole 11.

In present embodiment, roller 33 is equipped under 31 lower surface of sideslip substrate and pedestal between 22 upper surface, It may be ball, keep the translation of sideslip substrate 31 more smooth；The lid 1 is evenly arranged with five fence holes 11, described The downside of lid 1 is equipped with five leakage prevention sheets 3, when lid 1 does not stress described in five leakage prevention sheets 3 be staggered and set with five fence holes 11 It sets.

Drain cover in the present invention, after when pedestrian walks, foot is stepped down on lid 1,1 forced compression of lid is vertically multiple Position spring 121 simultaneously slightly moves down, and the first rack gear 122 moves down during being somebody's turn to do, and rotates the gear engaged, gear set 322 It starts to work, power is transferred on the second rack gear 32 engaged with gear set 322, and then make sideslip substrate 31 together with leakage prevention sheet 3 It moves together, leakage prevention sheet 3 is made to be moved to the lower section in fence hole 11, play the effect of leakproof, small articles do not fall out sewer In.After the foot of pedestrian leaves, lid 1 moves up under the effect of vertical reset spring 121, while the first rack gear 122 moves up, and make with Its meshed gears rotates backward, and then resets sideslip substrate 31 together with leakage prevention sheet 3, and fence hole 11 is opened again, no Normal draining is influenced, it is very convenient.

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