Description
The utility model relates to drawing back of a kind of curtain and closure (lifting) device.
Sun blind are both artistic and practical, are particularly suitable in uses such as family, office spaces, and its aperture is regulated with take down the exhibits general using adjusting rod and rolling rope.
The CN2150789Y patent provides a kind of sun blind multi-functional modulator, mainly connect with vertical driving wheel group with the cross head coupling mechanism by adjusting rod, a drive of vertical driving wheel group is installed respectively in the rotating shaft and is regulated rope and connect core, aperture is regulated rope and is connected on the adjusting rope connection core, rolling rope position and lock device is housed on the adjusting rod, the rolling rope passes adjusting rod center cavity and position and lock device via pulley, to handle taking down the exhibits of sun blind.Because rolling rope and adjusting rod are integrated, and be interrelated, therefore firmly bigger, parts damages rate height, and locate unreliablely, and operation is inconvenient, and fault is many.
The CN2140678Y patent provides a kind of electrically driven curtain headstock gear, is made up of shell, gear, main shaft, reel etc., and a sun blind reel also is housed on main shaft, utilizes the able to turn on or off textile curtain of conversion and the sun blind of shift fork.
The CN2140189Y patent provides the drive shaft rod device of another kind of lifting curtain, and it is to be installed on the holder in the beam frame of hollow, and matches with pulling device, and drive shaft rod is made up of two pipes, two drive blocks, two drive blocks, screw rod and rope.Drive and be fixed in respectively in the outboard end of two pipes soon, two drive blocks are fixed in respectively in the medial extremity of two pipes, screw rod two ends spiral shell is solid in two drive blocks, two pipes are linked together, rope ends is separately fixed on the two pipe side faces, the turning cylinder of pulling device be nested with two drive blocks one of them, furl, open up the receipts curtain with the rotating drive axostylus axostyle.
Said apparatus and curtain join together in structure, and structure is complicated, and fault is many, damages easily.
It is strong that the purpose of this utility model aims to provide a kind of independence, separates with curtain aperture governor motion, not fragile, and the location is reliable, and fault is few, sun blind semi-automatic lifting device easy and simple to handle.
This device comprises lid, reel, axis, torsion spring, Positioning Gear, retainer spring, reference column, backguy and securing member.Reel is established the perforation centre bore, to insert axis, establishes 3 locating holes of symmetrical distribution in the center of reel one side through hole periphery, respectively inserts retainer spring in the hole, respectively puts reference column on the retainer spring.Establish the torsion spring circular groove at the opposite side of reel, establish a skewed slot at torsion spring circular groove groove edge, torsion spring places in the torsion spring circular groove, and the end of torsion spring outer ring is solidly plugged in the skewed slot of torsion spring circular groove groove edge.Establish the spiral groove on the excircle of reel, bottom land is established a through wires hole to the torsion spring circular groove, and an end of backguy passes through wires hole and fixes it.Axis is divided into torsion spring fixed axis, gear piece, positioning tooth wheel shaft and binding thread axle successively, and the torsion spring fixed axis that is positioned at axis one end passes the reel centre bore, establishes the torsion spring holddown groove on the torsion spring fixed axis, and the end of torsion spring inner ring is inserted solid in the torsion spring holddown groove; The gear piece is close to the opposite side of reel.Positioning Gear is established the center through hole, is inserted in the Positioning Gear shaft part of axis, and the medial surface of Positioning Gear is established the tooth of pitch face, and the number of teeth is the integral multiple of reference column number; The lateral surface of Positioning Gear is preferably established bulge loop.Lid before and after lid divides, lid is established fixing hole and wire hole, and the axis locating hole is established at the center of front cover body, and the axis locating hole is inserted on the binding thread axle of axis.
Also can establish the torsion spring washer on the torsion spring holddown groove, through hole is established at the catch center, is inserted on the torsion spring fixed axis.Can establish in addition the breach of symmetry, with fixing front cover body at positioning tooth wheel shaft edge.
The backguy other end of the present utility model only need pass cross tube, the blade advance decline line hole of sun blind, is connected with sheer pole again, can use.When sun blind need descend, the sheer pole of pulling sun blind down, backguy promptly drives reel and rotates, the skewed slot by the torsion spring circular groove edge on the reel rotates torsion spring, when stopping drag, Positioning Gear is located reel by reference column and retainer spring.When sun blind need rise rolling, only need the sheer pole of sun blind one is pushed up vertically upward gently, reel is eliminated the positioning action of Positioning Gear under the drive of torsion spring, drive backguy upwards, makes the sun blind rolling.Install because this device is independent, simple in structure, not fragile, its location is reliable, and fault is few, and operation is very easy.
Fig. 1 is an exploded view of the present utility model.
Fig. 2 is the torsion spring circular groove and the torsion spring position view of reel of the present utility model.
As Fig. 1, the utility model is made up of front cover body (1), rear cover body (2), reel (3), axis (4), torsion spring (5), Positioning Gear (6), retainer spring (7), reference column (8), backguy (9) and securing member (10) etc.Forward and backward lid can be plastic injection piece, is oblate tubular, and the one side is established extension (13,23) respectively, and establishes fixing hole (14,24), and opposite side is established wire hole (12,22) respectively, and axis locating hole (11) is established at the center of front cover body.Reel is established and is connected centre bore (31), so that insert axis.Periphery at the center through hole of reel one side (33) is established 3 locating holes (32) of symmetrical distribution, respectively inserts retainer spring (7) in the hole, respectively puts reference column on the retainer spring.Establish torsion spring circular groove (35, referring to Fig. 2) at the opposite side (34) of reel, establish a skewed slot (36) on the groove edge of torsion spring circular groove, torsion spring places in the torsion spring circular groove, and the end of torsion spring outer ring (51) are solidly plugged in the skewed slot of torsion spring circular groove groove edge.Establish spiral groove (37) on the excircle of reel, bottom land to torsion spring circular groove is established one and is connected through wires hole (38), so that an end of backguy passes the through track hole and fixes it.
