Abstract

The utility model provides a shutter which comprises a window sash frame body and hinges whose both ends are hinged on rods on the left and the right sides of the window sash frame body. The utility model is characterized in that each hinge is composed of a rotating shaft and a light shading blade connected to the connecting shaft. The end of one side of the rotating shaft is connected with a driven gear. Drive mechanisms engaged with each driven gear are arranged in the inner chamber of a vertical rod on the side part of the frame body.

Description

Shutter

The utility model belongs to a kind of shutter.

A kind of shutter commonly used on the present market, be to adopt in the top cross bar inner chamber of shutter, to be provided with a pair of gear that is meshed, the reversing bar that its driving gear and user adjust blade angle joins, its driven gear is a tumbler gear, and link to each other with rotating shaft, the rope and the line between the rope that are wrapped in the rotating shaft rely on the deadweight handling between each line in each blade, when the user horizontally rotates reversing bar, driving gear rotates, become vertical rotation through tumbler gear, rotating shaft is simultaneously rotated thereupon, rope one side that is wrapped in the rotating shaft is raised, and opposite side is put down, and the line between a rope also side is raised, opposite side is put down, and is placed on rope line blade and has changed corner thereupon.This shutter, the reversing bar of adjusting blade exposes, and operation inconvenience, and blinds all adopts plastic products can only shading, regulates light.

The purpose of this utility model provides a kind of shutter for this reason, and it not only is convenient to control, and firm safety.

For achieving the above object, the shutter that the utility model provides, comprise that window framework and two ends are articulated in the flap on the side lever of the window framework left and right sides, it is characterized in that: every fan flap is made up of rotating shaft and the cover blade that is connected in the rotating shaft, also is connected with a driven gear on a side end of rotating shaft; Be provided with the transmission mechanism that is meshed with each driven gear in the montant inner chamber of framework sidepiece.

The utility model owing to can open or close by the driven gear drive flap that transmission mechanism drives in the flap rotating shaft, thereby control conveniently, because all being connected in, each flap rotating shaft (as steel pipe) forms firm fence in the window framework in addition, thereby the robber can't inlet chamber in, played the effect of safety guard, transmission mechanism is located in the montant of door and window framework besides, thereby does not influence outward appearance.

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

Fig. 1 is the utility model organigram.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is a transmission mechanism structural representation of the present utility model.

As shown in the figure, shutter of the present utility model, comprise that window framework 1 and two ends are articulated in the flap 2 on the side lever of the window framework left and right sides, is characterized in that: every fan flap 2 is made up of rotating shaft 3 and the cover blade 4 that is connected in the rotating shaft, also is connected with a driven gear 6 on a side end of rotating shaft 3; Be provided with the transmission mechanism 7 that is meshed with each driven gear 6 in the montant inner chamber 5 of framework 1 sidepiece.

Above-mentioned transmission mechanism 7 is made up of sliding rack 8 and a driving gear 9 that edge is located in the window framework montant inner chamber 5, the active flank of tooth of sliding rack 8 is meshed with driven gear 6, the passive flank of tooth of sliding rack 8 is meshed with driving gear 9, the outer end that the montant body is stretched out in the rotating shaft of driving gear 9 is connected with a runner 10, runner 10 is provided with movable latch 11, and the termination of latch 11 can be inserted in the locating hole 12 that is opened on the montant wall.

When user's rotating wheel 10, the driving gear 9 that is attached thereto is rotated, just driving the sliding rack 8 that the passive flank of tooth is meshed with driving gear 9 moves, sliding rack 8 mobile make with its initiatively the driven gear 6 that is meshed of the flank of tooth rotate, so also rotate (promptly realizing changing blade rotating angle) thereupon with cover blade 4 in driven gear 6 joining rotating shafts 3 and the rotating shaft.When the user inserts the latch on the runner 10 11 in the locating hole 12, can no longer rotate by fixed blade.

The utility model is reasonable in design, controls conveniently, and is safe and reliable, is the comparatively desirable novel window blind in luxurious hotel, residential houses and office space.
