Abstract
The utility model discloses an automatic curtain winding structure which includes a drive wheel and a pull rope used for driving the drive wheel to rotate as well as a fixing frame used for installing the drive wheel; and a connecting rod is also connected with the fixing frame. The automatic curtain winding structure is characterized in that the lower end of the connecting rod is provided with a driven wheel; a digging rope without beads is twisted on the drive wheel and the driven wheel. As the digging rope is not provided with a bead-shaped substance, the contact between the digging rope and a roller is free from impact; therefore, no noise is generated and the goal of science is reached; moreover, as the phenomenon of bead blocking is avoided, the automatic curtain winding structure is winded more flexibly.
Description
Technical field
The utility model relates to a kind of curtain manual coiling structure.
Background technology
Current hand-operated curtain winding-structure all is the rope sheave that has pearl with a kind of, is commonly called as pelletron.Pull moving pelletron, pelletron drives initiatively reel rotation, reaches the purpose of rolling or fall curtain; Because bigger noise takes place in the collision of pearl and roller in the pelletron, and the people is not felt well, when especially having a rest in the office space or needing peace and quiet, it is suitable not feel well especially; As the patent No. is that the Chinese patent of 200810062760.X discloses a kind of curtain manual coiling structure, comprise roller, chain rope, fixed mount, on the described chain rope fixed interval have can with the chain pearl of groove transmission on roller engagement, its spy is being also to be connected with on the described fixed mount straight down a brake bar, and brake bar is provided with and can goes into but the snap ring that do not allow the chain pearl to pass for the chain wire clips; Owing to use the stay cord of pearl chain, sometimes when the pulling pelletron stuck phenomenon can appear, also because a variety of causes, make pearl loosening in stay cord, the rope slippage causes two pearls to contact, thereby can't spur, prior reason is to adopt band pearl pelletron, in drawing process, can send " chuckleing " noise, influence people's rest work, require further improvement design.

As improvement, described driving wheel is distributed with a plurality of coiling acute angle profiles of tooth that are used for rolling and is used for discharging on the tangent circumference coiling obtuse angle profile of tooth, and the coiling acute angle profile of tooth number that is used for rolling is more than the coiling obtuse angle profile of tooth number that is used for discharging.
As improvement, the middle part of described fixed mount has an installation shaft, and described driving wheel is installed in rotation on the described installation shaft by bearing, and adopt in the front portion of described installation shaft jump ring with the driving wheel axial limiting on this installation shaft.
Improve again, be lined with the first iron cover between described installation shaft and the bearing, between installation shaft and driving wheel, be provided with back-moving spring.
Further improve, also be arranged with pad on the described installation shaft, this pad is between jump ring and driving wheel.
As improvement, described fixed mount includes fixedly iron plate and mounting seat, described installation shaft is located on the mounting seat, and on installation shaft, has a perforation, described connecting rod is located on the mounting seat, fixedly the middle part of iron plate has the cutting that can insert described perforation, and fixedly the horizontal part of iron plate has installing hole.
Further improve, described connecting rod is by head rod, second connecting rod, the 3rd connecting rod is connected in sequence, one end of head rod is fixed on the mounting seat, the other end of head rod has through hole, there is screw to pass the mounting hole of an end on the through hole on the head rod and second connecting rod, and be connected and fixed by nut, the upper end of the 3rd connecting rod has and the identical hole of through hole on the head rod, the 3rd connecting rod utilizes screw to pass the mounting hole of the second connecting rod lower end, fix by nut, the lower end of the 3rd connecting rod is fixed on down on the face shield.
At last, described face shield down and last face shield are connected to form a case by screw, and follower is arranged in the case.
Described face shield down middle part has one, is arranged with the second iron cover on this axle, and follower is located at second iron rotationally by second bearing and puts.
Compared with prior art, advantage of the present utility model is: because stay cord is not with pearl, do not have impact with contacting of driving wheel in drawing process, thereby a silent, reach quiet purpose, also do not make when reeling more easy and flexible owing to block the phenomenon of pearl; Profile of tooth on the driving wheel has directionality, and the tooth of rolling is more than the tooth that puts down, make things convenient for casement roll and put down smooth and easy; Make traditional sprocket wheel into driving wheel and can also save cost, convenient processing; The two ends of second connecting rod have mounting hole, can will carry out telescopic adjustment between head rod, second connecting rod, the 3rd connecting rod by connector, and then regulate the degree of tightness of stay cord; Simple to operate, practical more, especially in public places or the recreating facility more suitable.
