The utility model has convenient installation, can automatically stop positioning at any position and can conveniently regulate the elastic force of the torsion spring, suitable to be applied on doors and windows to hang curtains or pictures.
Description
The utility model relates to the architectural decoration apparatus, especially for the roller blind device on door, the window.
At present, existing roller blind device has various types, but the curtain that uses on the most of door, window all adopts suspension type, and its roller blind device is mainly by spool, fixedly the support of spool and the spring in spool are formed.Locate mode is to use fixed hook spare, when loosen resilience torsion that Hook then relies on spring with curtain rollback spool on.This type of roller blind device does not have automatic location, and spring torsion can't be regulated after installation, and during the cord backrush, speed is too fast, poor stability.Other has a kind of self-align roller blind device, and its structure adopts the frame guide-localization, and its installation, operation are than more complicated complexity.
The purpose of this utility model provides a kind of self-align elastic type roller blind device that can locate at an arbitrary position.
The technical scheme that realizes the utility model purpose is: it has left socle, right support, reel, one end of reel and fixed cover load, be arranged on the mandrel in the reel and be set with torsion spring, and an end passes the axis hole and the right support load of fixed cover, it is characterized in that: the other end and autonavigator load that autonavigator and reel are housed on a, the left socle; B, a locating shaft pass and are contained in ball positioning sleeve and counterseal torsion spring in the positioning sleeve, and an end bearing is on the axis hole of left socle, and the other end is bearing on the centre bore of securing cover plate of positioning sleeve; Have the orientation direction groove on the side face of c, ball positioning sleeve, the inwall of positioning sleeve is provided with the positioning bead groove; Be provided with a location ball between d, orientation direction groove and the positioning bead groove.
When the pulling cord moves downward, the reel rotation, drive the positioning sleeve rotation in the autonavigator simultaneously, cooperating dies does not rotate and the ball positioning sleeve is because counterseal spring and locating shaft are fastened, at this moment, location ball between the positioning bead groove of orientation direction groove on the ball positioning sleeve and positioning sleeve is along with the rotation of positioning sleeve, in the orientation direction groove, orbit on the one hand, the aspect is again simultaneously along doing the axial trajectory operation in the positioning bead groove in addition, when pulling force is done the gap pause, under the effect of counterseal spring, the location ball is in position, dead angle in the orientation direction groove, and the ball positioning sleeve that can not rotate stops the positioning sleeve rotation to make the torsion spring can't be with cord lockup.
