Accompanying drawing explanation
Fig. 1 is the utility model structure sectional view.
As shown in Figure 1, floor drain body 1, removable cover 2, key return formula spring core 3, support 4, boss 5, upper strata annular groove 6, lower floor's annular groove 7, sealing mat 8, sealing ring 9, horizontal plane 10, vertical plane 11, bottom surface 12, drain hole 13.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, the special Split bouncing floor drain of a kind of rolling stock described in the utility model, comprise floor drain body 1, a removable cover 2 is set at the top of floor drain body 1, removable cover 2 and floor drain body 1 are splits, and can be elevated separately relative to floor drain body 1, floor drain body 1 is fixedly mounted on the floor of rolling stock washroom or lavatory, the below of floor drain body 1 connects the structures such as gutter, is directly communicated with outdoor or is communicated with waste water tank under car.
As shown in Figure 1, a key return formula spring core 3 is connected in the below of removable cover 2, the bottom of key return formula spring core 3 is fixed on the bottom surface 12 of floor drain body 1, passenger or crew can tramp with one's feet and step on removable cover 2, are realized spring up and down and the opening and closing function of removable cover 2 by key return formula spring core 3.Passenger or crew ride while removable cover 2 lifts again, and key return formula spring core 3 is upspring, and removable cover 2 is opened, and foot-operated removable cover 2 makes the key return formula core 3 that bounces return back to home position again, and removable cover 2 is closed.
The below of removable cover 2 is also provided with tubular support 4, the external surface of support 4 is provided with the three layers of ringwise boss 5 protruded laterally, three layers of boss 5 form upper strata annular groove 6 and lower floor's annular groove 7, one circle sealing mat 8 is installed in upper strata annular groove 6, install a circle sealing ring 9 in lower floor's annular groove 7, sealing mat 8 and sealing ring 9 are fixed by socket in upper strata annular groove 6 and lower floor's annular groove 7.
Floor drain body 1 is the two-stage step-like structure of heart convergence wherein, sealing mat 8 is in annular, and when removable cover 2 is closed, realize closely connected formation first by compressive strain between the soffit of sealing mat 8 and the horizontal plane 10 of higher level's step to seal, sealing area is larger between the two, sealing performance can be guaranteed, and, in the present embodiment, sealing mat 8 preferably adopts silica gel material, because silica gel material hardness is higher, can when vehicle operating produce negative pressure, sealing mat 8 can not produce moderate finite deformation and cause seal failure.When removable cover 2 is closed, realize closely connected formation second by compressive strain between the vertical plane 11 of sealing ring 9 and subordinate's step to seal, while guarantee sealing performance, can reduce when vehicle operating produces negative pressure, on the impact of sealing mat 8, avoid sealing mat 8 seal failure further.When removable cover 2 is in open position, sealing mat 8 and sealing ring 9 do not participate in sealing.
The bottom of key return formula spring core 3 is fixed on the bottom surface 12 of subordinate's step of floor drain body 1, and offer multiple drain hole 13 in the bottom surface 12 of subordinate's step, when removable cover 2 is opened, ponding on floor enters in floor drain body 1 from the gap between removable cover 2 and floor drain body 1, then the drain hole 13 on bottom surface 12 is discharged.
For improving bulk strength and the decay resistance of floor drain body 1, in the present embodiment, floor drain body 1 adopts the integrative-structure made, and the thickness of floor drain body 1 and removable cover 2 is equal to or greater than 3mm.
In the present embodiment, as shown in Figure 1, removable cover 2 entirety, in a cambered surface, improves the good looking appearance effect of its entirety, is convenient to foot switch simultaneously.
When needing the ponding on floor to discharge, passenger or crew trample removable cover 2 downwards with pin and lift, and key return formula spring core 3 is upspring, removable cover 2 is opened, and current directly rush in floor drain body 1 China and foreign countries row, and drain discharge is large, unobstructed rapidly, and can not clog.
Passenger or crew be foot-operated removable cover 2 again, key return formula spring core 3 is made to return back to home position, removable cover 2 is closed, realize first by compressive strain between the soffit of sealing mat 8 and the horizontal plane 10 of higher level's step to seal, realize second by compressive strain between the vertical plane 11 of sealing ring 9 and subordinate's step to seal, whole floor drain body 1 is closed, floor ponding can be stoped outward to arrange, when can prevent again vehicle operating, produce the problem that negative pressure causes seal failure.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
