Detailed description of the invention
As shown in Figures 1 to 4, latch lock fixed pattern waterpower retains door from rinsing, and comprise door-plate 1, described door-plate 1 top is provided with rotating shaft 2, and described rotating shaft 2 two ends are stretched in drainage pipe matrix 3; The gravity that described door-plate 1 is positioned at rotating shaft 2 lower part is greater than the gravity being positioned at rotating shaft 2 upper part; Described door-plate 1 downstream is provided with the first connecting axle 4, and described first connecting axle 4 is provided with torsion spring, and described first connecting axle 4 two ends are stretched in drainage pipe matrix 3; Described first connecting axle 4 is provided with grab 5 and jacking block 6; Be provided with draw-in groove 5.1 bottom described grab 5, parallel described first connecting axle 4 of described draw-in groove 5.1 is arranged, and described door-plate 1 top can be fastened in described draw-in groove 5.1; Be provided with the second connecting axle 7 above described rotating shaft 2, described second connecting axle 7 two ends are stretched in drainage pipe matrix 3, and described second connecting axle 7 is provided with the first rocking arm 8 and the second rocking arm 14; Described first rocking arm 8 one end contacts with jacking block 6, and the other end is connected with the second connecting axle 7; Described second rocking arm 14 one end is connected with floating drum 9, and the other end is connected with the second connecting axle 7; The arm of force on described first rocking arm 8 is less than the arm of force on the second rocking arm 14; Described floating drum 9 is positioned at door-plate 1 upstream.Further, described draw-in groove 5.1 and the snap-latch surface 5.11 of door-plate 1 are provided with the section of agreeing with 5.12 to door-plate 1 upstream oblique.Like this, more mild in the reseting procedure of door-plate 1 and improve the reliability resetted.Further, described second rocking arm 14 bottom is inclined-plane 14.1, and described inclined-plane 14.1 can agree with door-plate 1.Like this, be more conducive to door-plate 1 reset.Further, described door-plate 1 top is provided with roller 10, and described roller 10 engages with described draw-in groove 5.1.Like this, in the process that grab 10 and door 1 board close, make snap-fitting process more level and smooth by the rotation of roller 10.Further, described door-plate 1 upstream is provided with water tank 11, and described water tank 11 is fixed on described matrix 3; Described floating drum 9 is positioned at described water tank 11; Described water tank 11 is provided with water inlet 11.1 and delivery port 11.2.Further, described matrix 3 is provided with valve seat 12, and described valve seat 12 is positioned at below door-plate 1, and described door-plate 1 can be tightly connected with valve seat 12.Like this, further increase the seal retained, ensure to retain effect.
Like this, under the effect of torsion spring, grab 5 rotates around the first connecting axle 4, and draw-in groove 5.1 engages with door-plate 1 top, thus closes runner 13, starts to retain; Along with the rising of door-plate 1 upstream canal 13 water level, floating drum 9 is floated, thus promotion the second rocking arm 14 rotates around the second connecting axle 7, jacking block 6 is promoted again by the first rocking arm 8, jacking block 6 drives grab 5 to rotate around the first connecting axle 4, and now, the torsion that grab 5 overcomes torsion spring is separated with door-plate 1, door-plate 1 opens runner 7 under the effect of current, completes pre-washing function; After flushing completes, the first rocking arm 8 and the second rocking arm 14 reset, and grab 5 resets under the effect of torsion spring torsion, and engages with door-plate 1, thus is closed by runner 7, starts retaining of next cycle.
It should be noted that the annexation between grab 5 and the first connecting axle 4, between jacking block 6 and the first connecting axle 4 can be rotationally connected, now, the first connecting axle 4 is fixed with matrix 3, and grab 5 and jacking block 6 are fixed; Annexation between grab 5 and the first connecting axle 4, between jacking block 6 and the first connecting axle 4 also can be fixing, now, be be rotationally connected between first connecting axle 4 and matrix 3, grab 5 and jacking block 6 can be fixed with the first connecting axle 4 respectively, also jacking block 6 can be fixed on grab 5.
Equally, the annexation between the first rocking arm 8 and the second connecting axle 7, between the second rocking arm 14 and the second connecting axle 7 and the annexation between grab 5 and the first connecting axle 4, between jacking block 6 and the first connecting axle 4 similar, then this just repeats no more.
Under original state, runner 13 is closed by door-plate 1 and valve seat 12, and door-plate 1 is fastened in draw-in groove 5.1 by grab 5, and now anhydrous in water tank 11, the water level in the runner 13 of door-plate 1 upstream rises gradually, as shown in Figure 1.
Gradually, water level rises in the process of peak gradually, and water enters water tank 11 through water inlet 11.1, and the water in water tank 11 reaches necessarily, promote floating drum 9 to rise, therefore produce unlatching moment, the second rocking arm 14 is rotated around the second rotating shaft 7, then promotes jacking block 6 by the first rocking arm 8, jacking block 6 drives grab 5 to rotate around the first connecting axle 4, make door-plate 1 depart from the engaging of draw-in groove 5.1, thus realize pre-washing function, as shown in Figures 2 and 3.Certainly, at water tank 11 from the process that door-plate 1 upstream intakes, delivery port 11.2 is also and water tank 11 external communication always, but is in water-filled runner 13 always, therefore cannot draining.
After flushing completes, door-plate 1 cuts out 90% under the effect of self gravitation, and the water in water tank 11 is discharged gradually through delivery port 11.2, and the first rocking arm 8 and the second rocking arm 14 reset; Grab 5 resets gradually under the effect of torsion spring, thus close door-plate 1 last 10%, start retaining of next cycle, as shown in Figure 4.
