Abstract
A kind of electric-hand driven two-purpose curtain, its screw mandrel is contained in the interior left and right bushing of curtain rod arm housing, the screw mandrel middle part has left and right sides spiral, left and right screw is housed on the screw mandrel, the screw mandrel right-hand member is equipped with runner, and by the ball chain drive, screw mandrel can rotate by both forward and reverse directions by runner on the motor, make the curtain can move left and right, reach the purpose of switching along with screw.
Description
The present invention relates to a kind of electric-hand driven two-purpose curtain, belong to the technical field of daily necessities.
Present existing curtain mostly is to fix a hard iron wire or a wooden stick on the wall of window top, is sewed with garden ring or clip in the cord upper end, and is with pulling moving cord, not smooth when the galvanized wire of using distortion or wooden stick wearing and tearing pulling.
Also have transverse bar is housed in pelmet, being equipped with on the bar can be along the garden ring that bar slides, below the garden is encircled
Suspension hook is arranged, again with the cord hook on suspension ring, pulley is equipped with at two of bar, drive the casement move left and right with rope pulling suspension hook and reach the purpose of opening closed casement, its rope is sagging, and Yi Yubu, hook are around being associated in together, hard draw often causes damage again, neither attractive in appearance, use also inconvenience, demand urgently improving.
The objective of the invention is to provide a kind of electric-hand driven two-purpose curtain, and it can overcome above-mentioned deficiency.
The object of the present invention is achieved like this, in the curtain rod arm shell, left and right bushing is housed, screw mandrel is contained in the axle sleeve, there is the screw thread of left-handed dextrorotation at the screw mandrel middle part, left and right sides screw is contained in above the screw mandrel, several slip rings also are housed on the screw mandrel, the little hook that hangs cord is equipped with in screw and slip ring lower end, the screw mandrel end has runner, be connected with little runner on the motor by the ball chain, screw mandrel rotates, and makes screw and slip ring move left and right, thereby curtain is also moved thereupon, and have can be at the roller of the slideway slippage of curtain rod arm bottom screw both sides, the left and right sides.
The front view of accompanying drawing 1, electric-hand driven two-purpose curtain
Fig. 2, screw cutaway view partly
The transmission diagram of Fig. 3, runner and ball chain
Now in conjunction with the accompanying drawings the structure of electric-hand driven two-purpose curtain is described in further detail.
By Fig. 1, at the two ends that curtain rod arm shell (4) is inner left axle sleeve (1) and right axle sleeve (8) are housed, the two ends, the left and right sides of screw mandrel (2) are contained in respectively in left axle sleeve (1) and the right axle sleeve (8), the middle part of screw mandrel (2) has left-hand screw (5) and right-hand screw (6) screw thread part, thereby left screw (5) is housed at screw mandrel (2) left end, screw mandrel (2) right-hand member is equipped with right screw, left side slip ring (3) and right slip ring (7) respectively are contained in above the screw mandrel, the slip ring of right quantity can be installed according to the length of leading screw, the leading screw right-hand member is equipped with runner (9), runner (9) is connected with little runner (11) on motor (12) axle by ball chain (10), and screw mandrel (2) can both forward and reverse directions rotation in left axle sleeve (1) and right axle sleeve (8).Thereby left and right sides slip ring (3) (7) is moved along screw mandrel, because left and right sides slip ring (3) (7), all there is hook (15) bottom of screw (5) (6) so make also closure or openness thereupon of curtain.
Fig. 2 is a screw cutaway view partly, two rollers (13) are equipped with at screw (5) (6) two ends, and there is a runway (14) lower end in the curtain rod arm, when leading screw is driven by runner (9), screw (5) (6) can horizontally slip on leading screw (2), and at this moment roller (13) just slides on runway (14).
The transmission diagram of Fig. 3 runner and ball chain, runner (9) and little runner (11) all are toothed sheaves, ball chain (10) is on rope many beads to be housed evenly, ball chain (10) in the groove of runner (9) (11) time bead contact and be driven with the groove flank.
Compared with prior art, electric-hand driven two-purpose curtain has following advantages:
1, simple in structure, electronic, manually can be dual-purpose.
2, screw utilizes roller to slide on runway, so the unlatching closure of curtain is all very nimble.
3, the disadvantage that similar cord and hook and ball chain are intertwined can not take place.
Claims (3)
1, a kind of electric-hand driven two-purpose curtain, it is characterized in that the interior two ends of curtain rod arm shell (4) are equipped with left axle sleeve (1) and right axle sleeve (8), screw mandrel (2) just is contained in the left and right axle sleeve, screw mandrel (2) middle part has left and right sides spiral (5) (6) screw thread partly, the screw mandrel left end is equipped with left screw (5), right-hand member has right screw, and left slip ring (3) and right slip ring (7) also are housed on the screw mandrel, and screw mandrel (2) right-hand member is equipped with runner (9) and links to each other with little runner (11) on motor (12) axle by ball chain (10).
2, two-purpose curtain according to claim 1 is characterized in that screw (5) (6) two ends all are equipped with roller (13), and there is runway (14) lower end in the curtain rod arm.
