Abstract
The utility model relates to the technical field of window curtain accessories, in particular to a rope winder without resistance. The rope winder without resistance comprises an overturning mechanism, a self-locking mechanism and a belt gear shaft. The overturning mechanism is arranged on the top of the rope winder, the self-locking mechanism is connected and arranged on a reset spring which is placed on one side of the overturning mechanism, and the belt gear shaft is arranged at the lower end of the reset spring. The rope winder without resistance is characterized in that two bearing bases are arranged under the overturning mechanism, an elevator belt winding disk is arranged between the two bearing bases, and the belt gear shaft is connected and mounted on an unlocking plate which is placed at the bottom end of one side of each bearing base. The rope winder without resistance is simple to manufacture and convenient to operate, a mechanical gear and the self-locking mechanism are combined so that operation can be achieved, once the self-locking mechanism is disengaged from the mechanical gear, the gear can start making non-resistance movement, a window curtain is made to rise and fall quickly, and accordingly zero-tension operation is achieved.
Description
Technical field
The utility model belongs to curtain tool accessory field, is specifically related to a kind of non-resistance ropewinder.
Background technology
Curtain is generally by stay cord scrolling, ropewinder is for it provides the gearing between rope body and curtain, serve as the device of storage rope body simultaneously, rely on the rotary action of reel for rope that rope is wound on reel for rope, the acting in opposition producing in the time of withdrawal cord body drives reel for rope to rotate, and then reaches the object of roll-up window shade.
Blind is as the one of curtain, it is to realize blade upset by the switching mechanism of ropewinder, and conventional ropewinder is generally to rotate switching mechanism by the clamping force of spring at present, and self resistance is very large, promote curtain feel very heavy, can not realize curtain fast lifting simultaneously.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of non-resistance ropewinder, comprise switching mechanism, self-locking mechanism, rotary gear shaft, described switching mechanism is located at outside, described self-locking mechanism connects and is located on the back-moving spring that is positioned at switching mechanism one side, described rotary gear shaft is arranged on back-moving spring lower end, it is characterized in that: described switching mechanism below is provided with two bearing bases, between described two bearing bases, be provided with elevator belt reel, described rotary gear shaft connects and is arranged on the unlock plate that is positioned at bearing base one side bottom.
As preferably, described switching mechanism comprises and is located at the circular shaft of right-hand member for the mobile use of overturning, and this switching mechanism top is provided with some recessed porous pits, side be middle part hollow out cylindric.
As preferably, described self-locking mechanism is one to be the slide block of T-shape structure, and two upper ends of slide block connect switching mechanisms, and bottom connects back-moving spring.
As preferably, described elevator belt reel is cylindrical-shaped structure, is provided with the grooved tracks of three parallel rings around cylinder on this column side face centre position, is respectively equipped with bearing base in this grooved tracks outside, in this elevator belt reel inside, bearing is installed.
As preferably, described rotary gear shaft is connecting the bearing that is located at elevator belt reel inside.
As preferably, described unlock plate is for fixed gear rotating shaft and elevator belt reel.
Beneficial effect:
The ropewinder that the utility model adopts technique scheme to provide, manufactures simple, easy to operate, utilize mechanical gear and self-locking mechanism to combine control operation, once self-locking mechanism departs from mechanical gear, gear just starts to do resistanceless motion, can make curtain fast lifting, realize zero pulling force operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, switching mechanism 1, self-locking mechanism 2, back-moving spring 3, rotary gear shaft 4, unlock plate 5, bearing base 6, elevator belt reel 7.
Detailed description of the invention
As shown in Figure 1, a kind of non-resistance ropewinder, comprise switching mechanism 1, self-locking mechanism 2, rotary gear shaft 4, described switching mechanism 1 is located at outside, described self-locking mechanism 2 connects and is located on the back-moving spring 3 that is positioned at switching mechanism 1 one sides, described rotary gear shaft 4 is arranged on back-moving spring 3 lower ends, it is characterized in that: described switching mechanism 1 below is provided with two bearing bases 6, between described two bearing bases 6, be provided with elevator belt reel 7, described rotary gear shaft 4 connects and is arranged on the unlock plate 5 that is positioned at bearing base 6 one side bottoms, described switching mechanism 1 comprises and is located at the circular shaft of right-hand member for the mobile use of overturning, this switching mechanism 1 top is provided with some recessed porous pits, it is cylindric that side hollows out in the middle part of being, described self-locking mechanism 2 is one to be the slide block of T-shape structure, two upper ends of slide block connect switching mechanism 1, bottom connects back-moving spring 3, described elevator belt reel 7 is cylindrical-shaped structure, on this column side face centre position, be provided with the grooved tracks of three parallel rings around cylinder, be respectively equipped with bearing base 6 in this grooved tracks outside, in these elevator belt reel 7 inside, bearing is installed, described rotary gear shaft 4 is connecting the bearing that is located at elevator belt reel 7 inside, described unlock plate 5 is for fixed gear rotating shaft 4 and elevator belt reel 7.
When real work, blind ladder band is arranged on switching mechanism 1.By self-locking mechanism 2 lock gear rotating shafts 4, in the time pulling blind head processed to rotate, a system output iron bar driven gear rotating shaft 4 is rotated; Rotary gear shaft 4 drives switching mechanism 1 to rotate by self-locking mechanism 2 simultaneously, and in the time turning to certain angle, thereby self-locking mechanism 2 is encountered unlock plate 5 disengaging rotary gear shafts 4, is rotated and controls shutter elevating together with elevator belt reel 7 by rotary gear shaft 4; When stopping operating when without external broach, back-moving spring 3 pins switching mechanism 1 and rotary gear shaft 4 automatically.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as switching mechanism 1, self-locking mechanism 2, back-moving spring 3, unlock plate 5 herein, do not got rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
