Abstract
The utility model provides a curtain-pulling device, which comprises a screw, a motor and a hanging ring. The utility model is characterized in that the screw of the curtain-pulling device is a fully screw rod. The width of the hanging ring arranged on the screw is larger than the width of the rotary groove of the screw. The inner wall of a drive ring is provided with a protruding part matching with the rotary groove of the screw. The utility model has the characteristics of simple structure, reasonable design, fewer drive components and helpfulness for processing, low manufacture cost, stability and reliability of opening and closing curtains, low noise and long service life.
Description
Technical field the utility model relates to a kind of device of hanging curtain, especially for curtain or analog draws back or closed controller for curtain.
The spiral window curtain holder of curtain is closed or opened to background technology from both direction, mostly adopts two not screw rods on same straight line, the motor-driven that two screw rods is provided with by correspondence respectively.Its deficiency is: the parts that curtain adopts are many, the cost height, and it is big to take up space.Adopt the curtain rod arm of a screw rod, there is screw thread at the middle part of its bar, and two ends are polished rod.Near the tension force boss being set on the polished rod of thread segment, it is used for preventing that the head end Curtain ring from entering the polished rod section, enters spiral section or will can enter under certain pulling force or thrust from other Curtain ring that spiral section enters into the polished rod section from the polished rod section simultaneously.Its complex structure, the processing trouble, the running resistance of Curtain ring is big.
The summary of the invention the purpose of this utility model is to provide folding simple and reasonable, curtain the reliable controller for curtain that operates steadily.
The purpose of this utility model realizes by following measure: controller for curtain comprises screw rod, motor, link, the screw rod that it is characterized in that controller for curtain is the full thread bar, be positioned at link width on the screw rod greater than the width of screw spiral trough, it initiatively encircles inwall and is provided with the lug boss that matches with screw spiral trough.The screw rod that the utility model provides can be for unidirectional screw thread or from the left and right screw thread of the middle part of bar boundary, promptly can be from a direction or two-way folding curtain.So only need a motor can finish driving.The helical angle of screw rod is less, the ridge broad, and the spiral fluted width is less, has formed the oblique line screw thread, can make screw rod be in ultra low speed operation like this, but draws the speed of curtain not subtract, and promptly reduces wearing and tearing, reduces noise again, improves service life.Because the width of link is greater than the spiral fluted groove width, therefore link does not drop in the helicla flute, each link is moving by the active endless belt along the walking of screw rod, first ring is for initiatively encircling (two-way folding is two initiatively rings), its inwall has the lug boss that matches with helicla flute, and this lug boss is the projection in the insertion groove, when closing curtain, the rotation of screw rod makes initiatively to encircle and moves, and drives driven torus.When opening curtain, the mobile promotion driven torus of active ring.In order to guarantee that two curtains are closed fully, initiatively ring is provided with outward extending horizontal hangers, and after initiatively ring arrived and closes the position of curtain, the horizontal hangers that stretches out made two curtain closures.Controller for curtain also is provided with travel control switch, its control strip is arranged on the link, on the sheath of screw rod outside, be provided with light-operated switch by control strip control, link moves to the position that control strip blocks the light-operated switch optical signal, motor power will be cut off automatically, and this moment, curtain just in time was in the position of closing or opening.If the screw rod of controller for curtain is longer, in the middle support component can be set.For the ease of processing, screw rod can adopt two butt joints to form, and joint connects with spring bearing, so still can be with its rotation of driven by motor.Be provided with downward opening sheath in the outside of screw rod, the sheath opening part is provided with symmetrically arranged along its length two guide rails 11, is used to limit the swing of link, and the link suspension rod can only moving linearly.
Characteristics of the present utility model are; Simple in structure, reasonable in design, used driver part is few and be convenient to processing, and cost is low, and the folding of curtain operates steadily reliably, and noise is little, long service life.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the B-B of Fig. 1 is to cutaway view;
The structural representation that Fig. 3 initiatively encircles for the utility model.
The specific embodiment is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, 3, present embodiment provides a kind of controller for curtain from both direction folding curtain, it mainly is made of screw rod 1, link 2,3, carriage 5, motor 9, travel control switch, sheath 6 etc., screw rod is to be made of the opposite full thread bar of the hand of spiral of two butt joints, joint links into an integrated entity by bearing 8, one end of screw rod is connected with motor, and spring bearing is also established at the two ends of bar.Screw thread on the screw rod is the oblique line screw thread, and its helical angle is less, the ridge broad, and the spiral fluted width is less.Link be by initiatively encircle 2 and driven torus 3 constitute, the width of link is greater than the spiral fluted width, link does not drop in the groove.Two inwalls that initiatively encircle are provided with and are inserted in the helicla flute and the projection 4 that matches with it, and the rotation of screw rod will promote projection and the active ring is moved.Initiatively be connected with horizontally disposed hangers 10 on the suspension rod of ring, be used to connect curtain, after two initiatively the position of curtain was closed in ring arrival, two hangers that stretch out made two curtains closed fully.The suspension rod of driven torus is connected with curtain.Be provided with downward opening sheath in the outside of screw rod, it is hollow pipe that the sheath opening part has two guide rail 7, two guide rails that are provided with along its length.One of them pipe is provided with opening 11 along its length, the control strip 12 that is arranged on a travel control switch in the active badly is in opening extend into pipe, be positioned at two light-operated switches 13 of hollow pipe, be separately positioned on open or close curtain after initiatively encircle relative position, present position, as moving to Figure 1B-B to cuing open the position that shows when initiatively encircling, initiatively the control strip on the ring just in time blocks light-operated switch, travel control switch will cut off motor power, this moment, curtain just in time was in the position of opening, and the terminal procedure of opening curtain is control automatically.In like manner, the terminal procedure of closing curtain also is control automatically, and promptly initiatively belt to the position that curtain is closed, initiatively the control strip on the ring blocks light-operated switch.
Claims (5)
