Specific embodiment:
The utility model is further described with specific embodiment below, referring to Fig. 1-6:
A kind of limiter includes the mounting base 1 of setting on the shutter, further includes having screw rod 2 and being threaded in
Slider nut 3 on screw rod 2, the mounting base 1 include sliding slot 4, and the both ends of screw rod 2 are arranged in mounting base 1, slider nut
3 be located at sliding slot 4 in, screw rod 2 rotation drive slider nut 3 slided in sliding slot 4, be arranged on the one or both ends of screw rod 2 with
The limit plate 5 that screw rod 2 rotates synchronously, one end of the present embodiment screw rod 2 is provided with limit plate 5, suitable for the blinds unidirectionally limited
Window.Slider nut 3 is equipped with retention bead 6 close to the end face of limit plate 5, and limit plate 5 is equipped with compatible with retention bead 6
Fixture block 7, retention bead 6 carry out screw rod 2 with the conflict connection of fixture block 7 circumferentially positioned.Wherein limit plate 5 and screw rod 2 rotate synchronously,
2 rotate driving slider nut 3 of screw rod 4 horizontally slips along the chute, when slider nut 3 slides into limit plate 5, passes through retention bead
6 contradict connection with fixture block 7, to realize slider nut 3 to the circumferential position-limiting action of screw rod 2.
In order to optimize retention bead 6 and the inconsistent contact area of fixture block 7, the retention bead 6 is contradicted with fixture block 7
The one side of connection forms continuing surface, and continuing surface is plane or inclined-plane or arcwall face, and the present embodiment continuing surface is plane.
In order to reinforce the receiving load of retention bead 6, the retention bead 6 is to be arranged by the center of circle of the axis of screw rod 2
Annular or arcuate structure, the thickness of retention bead 6 become larger along the hand of thread spiral of screw rod 2.
In order to enable slider nut 3 to horizontally slip in sliding slot 4, and in sliding process, slider nut 3 and sliding slot 4
It does not wear, the slider nut 3 is located at the specific structure in sliding slot 4: the side wall of slider nut 3 and the respective side of sliding slot 4
Gap is provided between side wall, 3 one side wall of slider nut or two sidewalls have been downwardly extending anti-rotation boss 8, wherein when screw rod 2
Both ends are provided with limit plate 5, and anti-rotation boss 8 is downwardly extending by 3 two sidewalls of slider nut；When 2 one end of screw rod is provided with
Limit plate 5, anti-rotation boss 8 are downwardly extending by 3 one side wall of slider nut.The retention bead 6 contradicts connecting band with fixture block 7
The respective side side wall of dynamic anti-rotation boss 8 and sliding slot 4, which contradicts, to be connected.In actual use, due to screw rod 2 rotate load compared with
Height, when retention bead 6 and fixture block 7 are inconsistent, fixture block 7 applies a circumferential active force to slider nut 3 by retention bead 6,
The respective side side wall of anti-rotation boss 8 and sliding slot 4, which contradicts, to be connected, and the side wall of sliding slot 4 applies slider nut 3 by anti-rotation boss 8
Reaction force corresponding with circumferential active force is held to further improve the load connected between sliding slot 4 and slider nut 3
By intensity.
