Abstract

The utility model discloses a blade type movable sealing cover which has the advantages of artful structure, similarity to a shutter, small operating action, convenient opening and closing, tightness after closing, and good closing effect. Moreover, the cover body is ultrathin and can be conveniently arranged at the opening of various vessels. The utility model is characterized in that a chassis is an annular base, the upper surface of the ring is provided with a rotating disk which can rotate in a slot, and a set of shutter type blades are arranged. An upper cover (10) is buckled on the upper surface of the combined blades and is fixed with the base as a whole. A reset spring is arranged between a handle and the base, so that the set of blades are always in closed state. The utility model can be used as a movable upper cover for a toilet, a WC pan, or a spittoon.

Description

The movable closing cap of vane type

The utility model relates to a kind of the unlatching and closed lid arrangement, specifically a kind of keying that utilizes one group of blade to realize opening part by each blade synchronization rotation.

For the container type apparatus, for preventing that material is to the pollution of environment, for example toilet in its formation pollution of outer bound pair and the container, bedpan, spittoon and pressure vessels for the chemical industry need be added a cover able to turn on or off lid, the very convenient again unlatching of this lid, closure prevents that it from polluting surrounding environment again.Do not find at present a kind of desirable such lid of function as yet.

The utility model purpose is to disclose the movable closing cap of a kind of vane type.Its advantage is that structure is ingenious, is similar to shutter, and operational motion is little, unlatching and closed convenient, and tight after the closure, closure is good, and lid is ultra-thin, is installed on various vessel ports place very easily.

Below with reference to embodiment description of drawings ins and outs.

Fig. 1 for the utility model embodiment remove loam cake the time closure state figure.

Fig. 2 is the upward view of loam cake.

Fig. 3 is the blade external form figure among Fig. 1.

Fig. 4 is the A-A profile of Fig. 1.

Fig. 5 is opening figure.

The utility model is made up of one group of blade and base and vane operation handle and loam cake.It is characterized in that: chassis 1 is an annular base, the upper surface of ring has a circle annular groove, place the rotating disk that can in groove, rotate 2 in the annular groove, one group of fast gate-type blade 5, be distributed on the center of turntable opening, the rotating shaft end of blade 5 has two axis holes, the blade chassis axis hole 9 of an outer end, one is more inner rotating disk axis hole 8, and it is the elliptical aperture that tilts with diametric(al) that hole 9 is changeed on the chassis.All having a chassis axle corresponding with the axis hole of above-mentioned blade 3 and 4. 1 loam cakes 10 of turntable shaft to be fastened on above the combined blade on described rotating disk and the chassis is fixed as one with base, on blade towards blade one side, have spacing bar hole or groove 11 at corresponding turntable shaft place, a handle 6 is connected in rotating disk 2.A back-moving spring 7 is arranged between handle and the base, make one group of blade always be in closure state.There is at least one ball type locator at corresponding rotating disk place on the base, is made up of a steel ball and top, lower end spring.When rotating disk forwarded extreme position to, the spill that steel ball heads into rotating disk made the rotating disk location in sinking, and this spill has a button on sinking, and steel ball is rebounded, and makes rotating disk reset to former turned position.

The utility model can be used for toilet, closet or spittoon are made movable loam cake, be at ordinary times closure state as described in Figure 1, sealing surface by the synthetic opening of one group of vane group, when needing to open, move handle 6 and rotate rotating disk 2, rotating disk rotates at the base annular groove, and blade is rotated simultaneously with the track that datum axle and turntable shaft limit.Opening enlarges gradually, and the dial rotation angle is limited by the stopper slot of loam cake.At this moment the ball type stop makes it be positioned the rotary spacing place, when closed loam cake, as long as press the button of loam cake, and under back-moving spring 7 effects, rotating disk reversing, blade closure.

The utility model structure is ingenious, folding with convenience.The ultra-thin container that is applicable to that various need seal and need often to open covers.

Claims
