Description
Technical field
The utility model belongs to the daily life technical field, relates to a kind of curtain draw ring that is used on the automatic curtain machine, particularly a kind of cross bar rotate can drive that it moves horizontally the curtain draw ring.
Background technology
The closure or openness of curtain, fairly simple mode is a suspension ring formula curtain, this suspension ring formula curtain is that the annulus that will connect casement is linked on the cross bar of curtain suspension bracket, pull casement with hand and drive the annulus realization closure or openness that on cross bar, slidably reciprocate, or adopt stay cord to be enclosed within the closure or openness of annulus drive casement on the cross bar by the pulley pulling, this mode since the contact area of annulus and cross bar than the people, add the deadweight of casement, make the frictional resistance between annulus and the cross bar big, often cause and tear casement or annulus is blocked by stay cord, result in hand cramps for the closure or openness of curtain.In addition, by the closure or openness of manual pulling casement, operation inconvenience, and require great effort again.
In order to solve the above problems, by retrieval, find that Chinese patent discloses a kind of curtain slip ring (patent No.: 200720108366.6), comprise annulus with the connector that connects casement, it is characterized in that being provided with in the annulus two or more cavitys, inlayed rolling element in the cavity, cavity is opened on the internal circle of annulus, and described rolling element is from cavity mouth convex protrusion part spherical surface body.This patent has solved the bigger problem of frictional resistance between curtain slip ring and the cross bar, still to a certain extent, because the rolling element of this patent disclosure is embedded in the cavity, in use for some time, extraneous dust etc. can enter in the cavity, causes rolling element to use normally.In addition, the curtain slip ring of this patent disclosure can only be controlled by manual, if the user will control the unlatching of curtain in bed or just close and can't realize.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, proposed a kind of simple in structure, frictional resistance is little, can rotate drive its curtain draw ring that moves horizontally by cross bar.
The purpose of this utility model can realize by following technical proposal: a kind of curtain draw ring, be arranged on the cross bar, the body that comprises ring-type, has the fixed part that is used for fixing casement on the described body, it is characterized in that, be fixed with two corresponding locating shafts on the madial wall of described body, be locating shaft one and locating shaft two, the fixing point two of the fixing point one of the madial wall of described locating shaft one and body and the madial wall of locating shaft two and body forms the straight line L of a level, described locating shaft one and locating shaft two distribute along straight line L left-right symmetry, axial restraint and circumferential the rotation are provided with bearing one on the other end of described locating shaft one, and axial restraint and circumferential the rotation are provided with bearing two on the other end of described locating shaft two.
Casement is to be fixed on the fixed part of body, and body is set on the cross bar, and bearing acts on the outer surface of cross bar.When cross bar rotated, bearing one and bearing two moved horizontally along cross bar, and bearing moves horizontally and drives whole curtain draw ring again and move horizontally, and were fixed on casement on the curtain draw ring also along with moving horizontally, thereby realized the unlatching of casement or close.The rotation of cross bar can be controlled by a motor, and the forward or reverse of motor can be controlled by remote controller.Certainly, during power failure, also can the curtain draw ring be moved horizontally along cross bar, thereby realize the unlatching of casement or close by manually driving the curtain draw ring.
In above-mentioned curtain draw ring, the axial line of described locating shaft one is a to the anticlockwise angle of straight line L, and the axial line of described locating shaft two counterclockwise is similarly angle a to straight line L.
As another situation, in above-mentioned curtain draw ring, the axial line of described locating shaft one is a to the clockwise angle of straight line L, and the axial line of described locating shaft two is similarly angle a to straight line L clockwise direction.
In above-mentioned curtain draw ring, the size of described angle a is greater than 0 ° and less than 90 °.
In above-mentioned curtain draw ring, also have the installation portion one and the installation portion two of protrusion on the madial wall of described body, above-mentioned locating shaft one is fixed on the installation portion one, and locating shaft two is fixed on installation portion two.
In above-mentioned curtain draw ring, described body adopts plastic material one-body molded.
In above-mentioned curtain draw ring, mode and installation portion one and the installation portion two of body of described locating shaft one and locating shaft two by cast is one-body molded.
Compared with prior art, the beneficial effect of this curtain draw ring is: roll on cross bar by bearing, frictional resistance is little, and cost is lower, and longer service life can match with the rotation of cross bar.
