Abstract

The utility model discloses a curtain slip ring, which comprises a circular ring with a connecting fitting for connecting the curtain. The utility model is characterized in that: two or more than two rolling elements are arranged in the circular ring, and part of the sphere face of the rolling element projects to the inner circle of the circular ring. The rolling elements in the circular ring are movable or fixed. The rolling elements are steel beads with smooth surface. Compared with the prior art, the utility model is provided with simple structure, low cost, convenient usage and free opening and closing.

Description

A kind of curtain slip ring

Technical field

The utility model belongs to a kind of opening and closing device of curtain, and it relates to curtain opening and closed slip annulus In-particular.

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 is because the contact area of annulus and cross bar is bigger, 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, for overcoming its defective, now nearly all be to adopt the mode that track-type facilities is set on the suspension bracket of curtain to solve curtain opening and closed operation problem freely, and the kind of track-type facilities, pattern, of a great variety, get up to mainly contain two classes but conclude, one class is the open type of " worker " font, another kind of is " built-in guide rail " closed type, though its guide rail sliding of these guide tracked curtain is good, curtain opening or closure are freely, but the one side that often breaks down is arranged also, and its component parts is more, structure is complicated, trouble is installed, maintenance is inconvenient, and price is also more expensive.

Summary of the invention

The utility model technical solution problem, provide a kind of simple in structure, easy to use, open and closure curtain slip ring freely.

For addressing the above problem, the technical solution adopted in the utility model is:

A kind of curtain slip ring, comprise annulus, in annulus, be provided with two or more cavitys, inlayed rolling element in the cavity with the connector that connects casement, on the internal circle of cavity chap annulus, described rolling element is from cavity mouth convex protrusion part spherical surface body;

The rolling element that is embedded in the annulus is movable;

The rolling element that is embedded in the annulus is fixed;

Described rolling element is ganoid steel ball.

The utility model is easy to generate when solving the closure or openness of suspension ring formula curtain tears casement or annulus is blocked defective by stay cord, having overcome ordinary person nearly all is the technology thinking of being developed to the technique direction that track-type facilities is set, but the mode that is difficult for discovering with ordinary person, in annulus, be provided with two or more cavitys with the connector that connects curtain, 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; When annulus is linked on the cross bar on the curtain suspension bracket, have only convex protrusion part spherical surface body to contact with cross bar, the annulus and the cross bar contact-making surface that have overcome in the original suspension ring formula curtain are excessive, the problem that frictional resistance is big, reduced the frictional resistance between annulus and the cross bar, adopting smooth steel ball is in order to have reduced its coefficient of friction.Compared with prior art, the utility model simple in structure, with low cost, easy to use, open with closed and move freely.

The specific embodiment

Embodiment one

As shown in Figure 1 and Figure 2, a kind of curtain slip ring, the annulus 1 with the connector 2 that connects curtain is to form with plastic injection-moulded, is provided with the cavity of settling rolling element 3 in the annulus 1, the cavity opening is on the internal circle of annulus; When rolling element need to be installed, after annulus 1 preheating, rapidly rolling element 3 is pressed in the cavity of annulus 1 from the cavity mouth, treat annulus 1 cooling after, cavity and the contraction of cavity mouth, rolling element 3 is fixed in the annulus.Present embodiment is that two cavitys and corresponding two rolling elements are set in the annulus, also plural cavity and corresponding rolling element can be set in annulus.

Embodiment two

As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, another kind of embodiment of the present utility model is provided, rolling element 3 among the figure is arranged in the mould with compression spring 4 in advance, it is once injection molded with compression spring 4 to have rolling element 3 that the annulus 1 of the connector 2 that connects curtain comprises in it, have in the annulus 1 and can supply rolling element 3 corresponding movable cavitys, the cavity mouth is opened on annulus 1 internal circle, the diameter of cavity mouth is much smaller than the diameter of rolling element 3, and rolling element 3 has only the part spheroid to come out from the convex protrusion of cavity mouth.Present embodiment is to have inlayed three rolling elements in annulus, also can inlay more rolling element in annulus.

Under user mode not, as shown in Figure 4, compression spring 4 in the annulus 1 is depressed rolling element 3 and is touched with cavity tight-lipped connecting airtight, when its in user mode, as Fig. 5, shown in Figure 6, because the weight of curtain itself is drop-down with annulus, the pressure that is arranged on the 4 pairs of rolling elements 3 of spring in the annulus less than or approximate the lower pulling force of curtain deadweight, rolling element 3 is moved back by withstanding in cavity of cross bar 6, the spheroid face that comes out from the convex protrusion of cavity mouth is not with cavity mouth EDGE CONTACT or contact not tight, at this moment rolling element 3 have only with compression spring and cross bar 6 up and down 2 contact, when the pulling annulus, rolling element 3 in the annulus 1 rolls on cross bar 6, so the closure or openness of curtain are quite easily.

Embodiment three

Present embodiment and embodiment two are basic identical, different is that embodiment two is the moving fulcrums that adopt spring mode regulation rolling element 3, and present embodiment is the activity of adopting the mode of stop collar 5 to come regulation rolling element 3: in like manner, rolling element 3 shown in Fig. 7, Fig. 8, Fig. 9 is arranged in the mould with stop collar 5 in advance, it is once injection molded with stop collar 5 to have rolling element 3 that the annulus 1 of the connector 2 that connects curtain comprises in it, this stop collar has been arranged, no matter it is to be in to use or user mode not, and rolling element 3 is under the movable state all the time.Present embodiment is to have inlayed four rolling elements 3 in annulus, also can inlay more rolling element body.

The smooth steel ball of rolling element 3 preferred surface described in the various embodiments described above.
