Description
Technical field
The present invention relates to a kind of shutter, more particularly to a kind of bead type shutter, belong to home decoration field.
Background technology
In current life, the utilization of bead type window shutter curtain is more and more wider, in office block, hotel, dining room, office
The figure of bead type window shutter curtain can be seen in room or family.Existing window shutter curtain uses in the market
It is wire type rope winder, each blade of window shutter curtain is fixed by the angular adjustment rope on wire type rope winder and angle
Regulation, then the opening of window shutter curtain and closing are controlled by the wiring on wire type rope winder, lifting rope passes through window shutter curtain
Window leaf on set hole be connected with each window leaf of window shutter curtain, by set on the window leaf of window shutter curtain
Hole is connected with the bottom of window shutter curtain；But the shutter of this structure is when closed, due to receiving rope winder structure
Limitation, and hole is provided with the window leaf of window shutter curtain, light leakage phenomena can occur when window shutter curtain is closed, have impact on blinds
The shaded effect of window.
Bead type window shutter curtain is because the difference of head processed can be divided into self-action and hand, wherein again because hand
Simple in construction, the features such as cost is low, maintenance maintenance facilitates, so the use range of hand is relative to the more wide of self-action
It is general.The manual bead shutter of in general is substantially by several parts groups such as install housing, tail processed, head processed, blade, drive shafts
Into.Wherein drive shaft both ends are connected respectively at tail processed with head processed, and head processed is installed on wall with tail processed by install housing,
Head processed also plays an important role in the course of work of blade in addition.Bead bead insertion in shutter is located in head processed
In sprocket wheel, people drives head sprocket wheel processed to rotate, head sprocket wheel processed is transmitted torque on drive shaft again, is driven by pulling bead
Drive shaft rotates, and realizes folding and the lifting action of blade.Existing head processed is controlling curtain with bead in the market
Pull the feel of bead poor, more painstaking during lifting, and use the shutter of this head processed in the folding and lifting of blade
Process nor especially steady, have impact on the using effect that people are shutter to manual bead.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, the invention provides a kind of simple in construction, shaded effect
It is good, cost is low, work when blade lifting is steady, labour-saving bead type shutter.
The technical solution adopted for the present invention to solve the technical problems is：A kind of bead type shutter, including install housing,
