The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

According to a kind of toilet dirt box sealing device shown in Fig. 1-3, mainly by dirt case lid 1, passage sealing gasket 2, dirt entrance 12 and sealing gasket 3 thereof, torsion spring 6, driving lever 7 and sealing O type circle 5, screw 8, slide plate 4 and fixed mount 9 thereof, screw 10, formed.Dirt case lid 1 covers and on dirt box 11, forms sealing, and dirt enters in dirt box 11 by dirt entrance 12, and driving lever 7 opens and closes with the control dirt entrance 12 that coordinates of slide plate 4.Concrete installation process is as follows: first 2 sealing O type circles 5 are installed on dirt case lid 1, be enclosed within the junction of slide plate 4, notice that driving lever sealing O type circle 5 can not have twisted phenomena, then by being stuck on dirt case lid 1 after sealing gasket 3, passage sealing gasket 2, before installation, need to add cementing; Again the slide plate 4 of the sealing O type circle 5 installing is before fixed on dirt case lid 1 inner surface by fixed mount 9, and with 5 pieces of triangle socket cap tapping screw 10 fixedly compactings; After finally dirt box torsion spring 6 being pressed into according to the torsion spring positioning port of dirt case lid 1, then according to the prominent groove on the square groove alignment slide plate 4 on driving lever 7, driving lever 7 is installed; And fixing urgent with 1 piece of triangle socket cap tapping screw 8; During installation, notice that torsion spring 6 must snap in driving lever 7 and dirt case lid 1 draw-in groove, with reach driving lever 7 in when action the auxiliary force by torsion spring 6, reduce the effect of self thrust.Torsion spring 6 is assemblied in the housing of dirt case lid 1, and its corresponding shell position has torsion spring 6 draw-in grooves, need to overcome self to reverse one end and be fixed on slide plate 4 during installation, and the other end is fixed on dirt case lid 1, then fixing by triangle socket cap tapping screw 8.When driving lever 7 is by external force during in opening, the rotation of driving lever 7 is also subject to the twisting resistance of dirt box handle torsion spring 6 except hand push external force, and power is rotated to slide plate 4, to reduce active force, makes its action; Otherwise driving lever 7 makes it closed by hand push power and torsion spring 6 twisting resistances when closure state.

According to the open and close state of the dirt box of toilet shown in Fig. 4-7 sealing device, on dirt case lid 1, fill respectively sealing gasket 3 and passage sealing gasket 2, fixed mount 9 is fixed on dirt case lid 1 by 5 pieces of triangle socket cap tapping screws 10, and slide plate 4 is that the track in arc, fixed mount 9 is also arc; When driving lever 7 is by external force during in opening, the driving lever 7 of take passes to slide plate 4 as axle center by the twisting resistance of external force and torsion spring 6, make it on the arc track of fixed mount 9, do movement in a curve, while reaching position-limited edge, slide plate departs from the dirt inlet seal pad 3 on dirt case lid 1, dirt entrance 12 is opened, and after toilet uses, the waste water in water tank flows in dirt box 11 through dirt entrance 12; When driving lever 7 is by external force during in closure state, the driving lever 7 of take passes to slide plate 4 as axle center by the twisting resistance of external force and torsion spring 6, make it on the arc track of fixed mount 9, do movement in a curve, while reaching reverse position-limited edge, dirt inlet seal pad 3 closures on slide plate 4 and dirt case lid 1,12 sealings of dirt entrance, to cut off dirt box 11 and extraneous being communicated with, reach sealing function.

Because whole operating process is all to take driving lever 7 as axle center, by external force and twisting resistance, pass to slide plate 4, in the arc track on slide plate fixed mount 9, move, be different from old-fashioned drawing and pulling type structure action; Greatly reduce Liao Qi internal motion mechanism space and placement space, to meet different occasions space, use and place, accomplished real portability.Driving lever circular motion, to optimize the sealing device of sealing and unlatching dirt box entrance, dwindles portable toilet and uses and placement space, adapts to the action need of various occasions, environment.

Most preferred embodiment of the present utility model is illustrated, and the various variations of being made by those of ordinary skills or remodeling can not depart from scope of the present utility model.
