The purpose of this utility model provides the reliable screen window positioner of a kind of positioning performance.
The purpose of this utility model is achieved in that this positioner is by spool 1, detent mechanism 2, torsion spring 3, support 4, axle 5, lining 28 and axle sleeve (6,7) constitute, it is characterized in that: described detent mechanism 2 is by locating shaft 9, axle sleeve 10, torsion spring 11, positioning sleeve 12, gland 13, bearing 16, shell 14 and alignment pin 15 constitute, locating shaft 9 is provided with strip projection 17, this projection 17 matches with the strip groove 21 of axle sleeve 10 inner rings, be wound with torsion spring 11 on the axle sleeve 10, hole 18 matches on one end 22 of torsion spring 11 and the positioning sleeve 12 outside the axle sleeve 10, and is compressed by gland 13; Have elongated slot 19 on the positioning sleeve 12, the other end 23 of torsion spring 11 embeds in this elongated slot 19, annular groove (24,25,26,27) also is set on the positioning sleeve 12, and the alignment pin 15 that can move in the groove on the positioning sleeve 12 (19,24,25,26,27) is fixed on the shell 14; The bearing 16 that is arranged on shell 14 tops matches with locating shaft 9; One end of axle 5 is fixedlyed connected with locating shaft 9, and the other end is with axle sleeve 6, and axle sleeve 7 is fixed on locating shaft 9 ends, and the two ends of torsion spring 3 are separately fixed on axle sleeve 6 and the axle sleeve 7; Lining 28 flexibly connects with support 4, and the strip groove 20 that can match with spool 1 all is set on shell 14, axle sleeve 6 and the lining 28.
The utility model has the advantages that accurate positioning is reliable.
Now in conjunction with the accompanying drawings and embodiments down to the utility model explanation:
Fig. 1 is the schematic diagram of prior art positioner;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a detent mechanism cut-away view of the present utility model;
Fig. 4 is the location structure three-dimensional exploded view;
Fig. 5 is the positioning sleeve expanded view;
Fig. 6 is the lateral view of positioning sleeve after launching;
Fig. 7 is the A-A cut-away view of Fig. 2.
Fig. 2 is the roller blind device structural representation of rolling curtain type screen window, constitute by spool 1, detent mechanism 2, torsion spring 3, support 4, axle 5, lining 28 and axle sleeve (6,7), characteristics of the present utility model are: this positioner is installed in the roller blind device, and it is made of spool 1, detent mechanism 2, torsion spring 3, support 4, axle 5, lining 28 and axle sleeve (6,7).Described detent mechanism 2 is made of locating shaft 9, axle sleeve 10, torsion spring 11, positioning sleeve 12, gland 13, bearing 16, shell 14 and alignment pin 15, locating shaft 9 is provided with strip projection 17, this projection 17 matches with the strip groove 21 of axle sleeve 10 inner rings, be wound with torsion spring 11 on the axle sleeve 10, hole 18 matches on one end 22 of torsion spring 11 and the positioning sleeve 12 outside the axle sleeve 10, and is compressed by gland 13; Have elongated slot 19 on the positioning sleeve 12, the other end 23 of torsion spring 11 embeds in this elongated slot 19, annular groove (24,25,26,27) also is set on the positioning sleeve 12, and the alignment pin 15 that can move in the groove on the positioning sleeve 12 (19,24,25,26,27) is fixed on the shell 14; The bearing 16 that is arranged on shell 14 tops matches with locating shaft 9; One end of axle 5 is fixedlyed connected with locating shaft 9, and the other end is with axle sleeve 6, and axle sleeve 7 is fixed on locating shaft 9 ends, and the two ends of torsion spring 3 are separately fixed on axle sleeve 6 and the axle sleeve 7; Lining 28 flexibly connects with support 4, and the strip groove 20 that can match with spool 1 all is set on shell 14, axle sleeve 6 and the lining 28.
Put window screening on the spool 1, if the original state window screening all twists on the spool 1, because the pin head of alignment pin 15 can move in positioning sleeve 12 upper grooves (19,24,2526,27), when window screening is pulled down, spool 1 drives shell 14 by the strip projection that matches with detent mechanism shell 14 grooves 20 and rotates, and (notes: promptly an end 23 of torsion spring 11 is embedded in the position of groove 19 from the A point positioning sleeve 12 upper grooves 24 in to be fixed on the pin head of the alignment pin 15 on the shell 14.) move to the B point, pin head at B point place alignment pin 15 drives positioning sleeve 12 around axle sleeve 10 rotations, thereby the window screening that twists on the spool 1 is moved down, when window screening reaches certain position and need locate, only need a little window screening is unlayed, promptly point moves to the D point to the pin head of alignment pin 15 along groove 25 from B, because an end 22 of torsion spring 11 embeds in the hole 18 of positioning sleeve 12, cover 12 screws so torsion spring 11 is positioned, and positioning sleeve 12 can not rotate again, at this moment, window screening is fixed on the desired position.
When window screening needs the up time receiving, only need a little that window screening is past once drop-down, make the pin head of alignment pin 15 in groove 26, move to the C point along the D point, then window screening is come loose, promptly point moves to the A point to the pin head of alignment pin 15 along groove 27 from C, the pin crown of alignment pin 15 firmly is stuck in an end 23 of the torsion spring 11 in the strip groove 19 at this moment, torsion spring 11 is unclamped, positioning sleeve 12 just can be around axle sleeve 10 backward rotation, drive spool 1 and roll window screening, when window screening reaches desired height and need locate, only need slightly window screening is pulled down to come loose then, the pin head that can make alignment pin 15 from groove 19 along groove (24,25) move to the D point from the A point, thereby window screening is located.
