Abstract
The utility model discloses a manual external sunshade shutter device, which comprises a shutter box body, a scroll, two guide rails, a curtain sheet and a hand rope winder, wherein the scroll is arranged in the shutter box body; the guide rails are arranged on the two sides of the shutter box body; the curtain sheet is wound on the scroll and moves up and down along the guide rails; the shutter box body is positioned between the upper ends of the two guide rails; one end of the scroll and the hand rope winder are connected through a tensioned traction rope; and a fixed pulley mechanism for changing the drawing direction of the traction rope is arranged just below the scroll. According to the manual external sunshade shutter device, the movement direction of the traction rope of the conventional shutter device is changed to be more natural, the unnecessary friction force is reduced, good operation of a system is protected better, and manual operation is more convenient and easier.
Description
Technical field
The utility model belongs to the building doors and windows technical field, relates in particular to a kind of manual external sunshade roller blind device.
Background technology
Routine pull band or hand wire rope external sunshade roller shutter window by the spool that is provided with in roller shutter casing, the roller shutter casing, guide rail, energy-conservation curtain sheet group, pull rope, pull rope and receive and to form around parts such as devices.Generally pull rope is drawn in the punching in the roller shutter casing upper right corner, extends to the forms positioned beneath and pulls the rope receipts around device.Because pulling rope receives around device and is fit to and can only be fixed on the window frame outside or the body of wall; And the pull rope exit is on the roller shutter casing; Pull rope is to move along oblique line driving in the process that reaches accommodation device like this; Can rub on roller shutter casing even the forms, pull rope damages easily and to spur resistance bigger, and Machine Movement Process has some setbacks.
The utility model content
The utility model provides a kind of pull rope can not touch the manual smoothly external sunshade roller blind device of roller shutter casing, pulling in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of manual external sunshade roller blind device; Comprise the roller shutter casing, be located at spool in the roller shutter casing, be located at two guide rails, the curtain sheet that is wrapped on the spool and moves up and down along guide rail of roller shutter casing both sides and pull rope and receive around device; The roller shutter casing is between the upper end that is positioned at two guide rails; Spool one end is received and between device, to be connected through tight pull rope with pulling rope, is provided with the fixed pulley mechanism that is used to change the pull rope draw direction under the said spool.
Said fixed pulley mechanism comprises installing rack; Installing rack is provided with horizontally disposed first fixed pulley of central axis and vertical second fixed pulley that is provided with of central axis; First fixed pulley be positioned at spool under with the inboard of guide rail; Second fixed pulley is positioned at the inboard of first fixed pulley; Pull rope is wrapped on first fixed pulley and second fixed pulley, and pull rope a section between spool to the first fixed pulley is vertical state, and the pull rope between first fixed pulley to the second fixed pulley a section and second fixed pulley are level to pulling one section that rope receives between device.
Adopt technique scheme; Owing under spool, be provided for changing the fixed pulley mechanism of pull rope draw direction; The installing rack of fixed pulley mechanism can be installed on window frame bottom or the wall; Installing rack also can be a pipe joint road, and first fixed pulley and second fixed pulley are located at respectively in the pipeline, and first fixed pulley and second fixed pulley will be in the pull rope of inclination extended state originally always and change into vertically and level; The pull rope between first fixed pulley to the second fixed pulley one section and second fixed pulley are level to pulling one section that rope receives between device, avoid producing additional friction; Thereby solved on rub easily when pull rope tiltedly draws roller shutter casing even the forms, pull rope damages and spurs the bigger technical problem of resistance easily.
The utility model has changed the direction of motion of conventional roller blind device pull rope, makes it more natural, has reduced unnecessary frictional force, has protected the good operation of system better, and manual operation is more easily convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the central A of Fig. 1 is to view.
The specific embodiment
As depicted in figs. 1 and 2; A kind of manual external sunshade roller blind device of the utility model; Comprise roller shutter casing 1, be located at spool 2 in the roller shutter casing 1, be located at two guide rails 3, the curtain sheet 4 that is wrapped on the spool 2 and moves up and down along guide rail 3 of roller shutter casing 1 both sides and pull rope and receive around device 5; Roller shutter casing 1 is between the upper end that is positioned at two guide rails 3; Spool 2 one ends are received and between device 5, to be connected through tight pull rope 6 with pulling rope, are provided with the fixed pulley mechanism that is used to change pull rope 6 draw directions under the spool 2.
Fixed pulley mechanism comprises installing rack 7; Installing rack 7 is provided with horizontally disposed first fixed pulley 8 of central axis and vertical second fixed pulley 9 that is provided with of central axis; First fixed pulley 8 be positioned at spool 2 under with the inboard of guide rail 3; Second fixed pulley 9 is positioned at the inboard of first fixed pulley 8; Pull rope 6 is wrapped on first fixed pulley 8 and second fixed pulley 9, and pull rope 6 a section between spool 2 to first fixed pulleys 8 is vertical state, and the pull rope 6 between first fixed pulley, 8 to second fixed pulleys 9 a section and second fixed pulley 9 are level to pulling one section that rope receives between device 5.
Owing under spool 2, be provided for changing the fixed pulley mechanism of pull rope 6 draw directions; The installing rack 7 of fixed pulley mechanism can be installed on window frame bottom or the wall; Installing rack 7 also can be a pipe joint road; First fixed pulley 8 and second fixed pulley 9 are located at respectively in the pipeline, and first fixed pulley 8 and second fixed pulley 9 will be in the pull rope 6 of inclination extended state originally always and change into vertically and level; The utility model has solved on rub easily when pull rope 6 tiltedly draws roller shutter casing 1 even the forms, and pull rope 6 damages and the bigger technical problem of pulling resistance easily.
