Embodiment:
See Fig. 1,2,3, the utility model comprises: rotating shaft 1, curtain screen 2, box body 3 and linkage assembly 4.Wherein curtain screen 2 adopts flexible materials to make, and a side of curtain screen 2 is fixed with rotating shaft 1.Box body 3 is made of left and right box body 31,32, the opening of left and right box body 31,32 is relative, its shaft 1 is articulated in the left box body 31, and be connected with elastic body between rotating shaft 1 and the left box body 31, as stated in the Background Art, this elastic body can be torsion spring or clockwork spring, rotates trend so that rotating shaft 1 has along a certain direction.Another side of this act screen 2 is fixed on the right box body 32, is connected with linkage assembly 4 between the left and right box body 31,32.
In conjunction with Fig. 4, linkage assembly 4 comprises linkage assembly 401 and lower link mechanism 402 in the utility model, wherein going up linkage assembly 401 is made of first connecting rod 41, second connecting rod 42 and extension spring 43, wherein an end of first connecting rod 41 is articulated in the upside of left box body 31, one end of its other end and second connecting rod 42 is hinged, the other end of second connecting rod 42 is articulated in the middle part of right box body 32, and extension spring 43 1 ends are connected on the second connecting rod 42, and the other end is connected in the top of right box body 32; Lower link mechanism 402 is identical with last linkage assembly 401 structures, and upper and lower linkage assembly 401,402 is symmetrically distributed, and wherein the second connecting rod in second connecting rod in the first connecting rod mechanism 401 42 and the second connecting rod structure 402 is articulated on the same bearing pin 44 that is positioned at right box body 32 middle parts.In addition, in this linkage assembly 4, first connecting rod 41 can oppositely be provided with second connecting rod mechanism 42.
In addition, also be provided with bayonet unit 5 on the box body 3, snap together so that left and right box body 31,32 is stablized.Bayonet unit 4 comprises block tongue 51 and the draw-in groove 52 that is arranged at respectively on the left and right box body 31,32 in the utility model, is connected with the buckle of draw-in groove 52 by block tongue 51 and realizes linking together of left and right box body 31,32.
When using the utility model, after opening bayonet unit 5, laterally spur left and right box body 31,32, make it separately.This moment is owing to be provided with an elastic body between left box body 31 and the rotating shaft 1, rotating shaft 1 will produce backward rotation trend under elastomeric effect, promptly curtain screen 2 will spur left and right sides box body 31,32 under rotating shaft 1 drives, and make it have the trend of closing up mutually, and the user need overcome this pulling force with box body 3 separately.In the process of separating, linkage assembly 4 will launch gradually, below above linkage assembly 401 is specified for example: upward first connecting rod 41 in the linkage 401 and second connecting rod 42 are along with a left side, right box body 31,32 separation and launching gradually, and a left side, right box body has the trend of closing up mutually under the pulling force effect of curtain screen 2, this pulling force also will act on first connecting rod 41 and the second connecting rod 42, make the first connecting rod 41 and the pin joint of second connecting rod 42 have the trend of moving downward (first connecting rod 41 and second connecting rod 42 are closed up), but along with separating of box body 3, second connecting rod 42 will be tending towards horizontality gradually, at this moment, the component of above-mentioned pulling force in the vertical direction diminishes gradually, overcome the component of above-mentioned pulling force in the vertical direction at last by the reversal interlocking relay of extension spring 43, make that interface point remains on this position and inconvenience between first connecting rod 41 and the second connecting rod 42.Same this moment is in order to guarantee that first connecting rod 41 and second connecting rod 42 do not continue to launch, need position linkage assembly on this 401, here adoptable mode is a lot, as can on left and right sides box body 31,32, position-limit mechanism being set, make first connecting rod 41 or second connecting rod 42 after being deployed into to a certain degree, can't continue to launch, perhaps preestablish the length of curtain screen 2, after curtain screen 2 is deployed into to a certain degree, can't continue to launch, thereby limit the expansion of linkage assembly 4, make it remain on this state.The utility model has adopted another kind of mode, to go up linkage assembly 401 and is crisscross arranged in lower link mechanism 402, like this when both are deployed into to a certain degree, because interlaced and can't continue expansion.When not in use, only need to apply certain external force, break the balance of linkage assembly 4, left and right sides box body 31,32 is closed up rapidly under curtain screen 2 drives.
The above only is a specific embodiment of the utility model, does not therefore limit its protection domain.
