Description
Affiliated technical field
The utility model relates to a kind of electrical Household appliance, particularly relates to a kind of transmission device of the electrically driven curtain without cable traction.
Background technology
At present, general indoor curtain commonly used is hand-operated curtain, carries out opening and closing operations with hand direct pull cord or with the hand drag rope, this kind Window curtain structure is simple, and is with low cost, is suitable for general family and uses, but operation inconvenience, outward appearance is simple and crude, and breaks down easily.Occur several electrically driven curtains in recent years on the market, affect the cord advance and retreat after adopting motor to slow down, and can increase some electronic component and change it into remote control, acoustic control or light-operated.This type of Window curtain structure is more advanced, and is easy to operate, and profile is more attractive in appearance, but these electrically driven curtains must use cable traction, and rope weares and teares easily or other faults take place, and operating reliability is relatively poor.Also have a kind ofly without cable traction in addition, and on each hangs the ring of cord two rollers with certain inclination angle are installed, this roller freely is suspended on the major axis, and when major axis rotated, roller promptly drove cord along axial-movement; This structure has been removed the trouble of cable traction from, but tractive force is very little, and structural strength is also lower, and number of rollers is a lot, and the reliability of complete machine is not high.
Summary of the invention
The purpose of this utility model provides a kind of without cable traction, does not also need the electrically driven curtain transmission device with powerful tractive force of rib-loop or tooth bar transmission, and this apparatus structure is simple, and is with low cost.
Technical solution of the present utility model is achieved in that as accompanying drawing 1,2, shown in 3, at a major axis 1 that is used to hang cord, two retainers 2 and a retainer 3 are housed, two turning rolls 4 are housed on each retainer, the little axle 6 of roller 5 usefulness is through on the turning rolls, retainer makes it keep the tram by outer cover 7, wherein be positioned at the top that the retainer 2 at two ends and turning rolls thereof and roller abut against major axis, retainer 3 in the middle of being positioned at and turning rolls thereof and roller abut against the below of major axis, retainer 2 is screwed on mount pad 8, mount pad 8 and outer cover 7 are screwed together on negative 9, mount pad 8 and base plate 9 also can be made into one, retainer 3 floats in outer cover, with spring 10 it is pressed on the below of major axis, simultaneously retainer 2 is pulled down, make it be pressed on the top of major axis, retainer 3 also can be without spring compression, and compresses with the screw fine setting.As shown in Figure 4, six rollers all keep certain inclination angle with the normal of major axis, and wherein the four rolling inclination angle on two retainers 2 is a degree, and the inclination angle of two rollers on the retainer 3 is-a degree.When major axis rotated, promptly along the axis moving linearly of major axis, when the major axis reverse rotation, complete unit i.e. motion round about for complete unit, and is being with the cord advance and retreat.
On a window curtain driving mechanism, can drive a width of cloth cord folding, also can use two transmission devices simultaneously, drive two width of cloth cords by the rightabout folding with a transmission device.
On all windows of heavy construction one side, can also drive all curtain and carry out folding with a major axis, and with a reducing motor as power.
Further improvement of the utility model is to increase remote control, achieves the curtain open/close remote control; Or increase acoustic control element is realized the curtain open/close acoustic control; Can also increase light-sensitive element, realize that curtain open/close is light-operated, when the sunlight direct projection, curtain is pulled on automatically, and after sunlight left, curtain drew back again automatically, and this kind form is applicable to auditorium, classroom, library or family.
After the utility model increases computer program, can also realize fully-automatic intelligent control.
The utility model has the advantages that, because this transmission device without cable traction, also do not need rib-loop or tooth bar transmission, but it has powerful tractive force.This device, on a width of cloth curtain, need only can spur view picture cord advance and retreat by a transmission device, must on each link, roller be installed, therefore simple and compact for structure, the reliability height is durable in use, and novel and beautiful appearance, with low cost, not only can be used for hotel, arenas, auditorium, office building and other luxurious places, and be suitable for the use of general family.

The specific embodiment
As accompanying drawing 1,2, shown in 3, at a major axis 1 that is used to hang cord, two retainers 2 and a retainer 3 are housed, two turning rolls 4 are housed on each retainer, the little axle 6 of roller 5 usefulness is through on the turning rolls, retainer makes it keep the tram by outer cover 7, wherein be positioned at the top that the retainer 2 at two ends and turning rolls thereof and roller abut against major axis, retainer 3 in the middle of being positioned at and turning rolls thereof and roller abut against the below of major axis, retainer 2 is screwed on mount pad 8, and mount pad 8 and outer cover 7 are screwed together on negative 9, and mount pad 8 and base plate 9 also can be made into one, retainer 3 floats in outer cover, with spring 10 it is pressed on the below of major axis, simultaneously retainer 2 is pulled down, make it be pressed on the top of major axis, retainer 3 also can be without spring compression, and compresses with the screw fine setting.
Shown in the accompanying drawing 4, six rollers all keep certain inclination angle with the normal of major axis, and wherein the four rolling inclination angle on two retainers 2 is a degree, and the inclination angle of two rollers on the retainer 3 is-a degree.When major axis rotated, promptly along the axis moving linearly of major axis, when the major axis reverse rotation, complete unit i.e. motion round about for complete unit, and is being with the cord advance and retreat.When motor just changeed, transmission device drove cord and advances, and during the motor counter-rotating, transmission device drives cord and retreats.If conversely with the roller incline direction, be about to original a and change into-a, change original-a into a, then the direction of motion of transmission device also will be opposite.Utilize this principle, can two opposite transmission devices be installed on a major axis, drive two width of cloth cords, when motor rotated, two width of cloth cords will close up or separate simultaneously simultaneously.Even the curtain that major axis can drive auditorium or all windows of side of theater simultaneously opens and closes simultaneously, and only uses a reducing motor.
