The utility model relates to a hand-operated device, which is composed of an elevating rope pulley component, a switching rope pulley component, a crank handle component and a frame, wherein, gear wheels on a shaft sleeve (13) are respectively meshed with gear wheels on a switching rope pulley (25) in the switching rope pulley component and big gear wheels (6) in the elevating rope pulley component by pushing in or pulling out a crank handle (15), thereby, the corresponding rope pulleys of the switching rope pulley component and the elevating rope pulley component are driven to rotate. The utility model can drive a curtain frame to elevate as well as drive the curtain to open and close, and has the advantages of novel and simple structure, small size, strong self locking capability, high safety, convenient operation, etc.
Description
The utility model relates to a kind of hand-operated device.
Curtain is the household articles of using always.At present the general useful hand direct pull curtain of manipulation of curtain, spur curtain, electricity consumption motor traction rope pulling curtain with rope, or the band remote control with the intelligent curtain operating mechanism of charged brain control.But these operating mechanisms are all just handled the on-off action of curtain, do not have to make the operating mechanism of curtain together with the curtain rod arm lifting.Because curtain is except that daily on-off action, also need install and mounting or dismounting during washing, so best curtain rod arm should lifting, with the convenient curtain of installing and removing.
The purpose of this utility model is to overcome the weak point of the single switching function that has the curtain operating mechanism now, provides a kind of and can not only make the curtain on-off action, can also make the hand-operated device of curtain together with the operating mechanism of curtain rod arm lifting action.
The utility model is made up of halliard wheel assembly, switching rope sheave assembly, wind assembly and frame.
Specifically describe structure of the present utility model and operation principle below in conjunction with embodiment and accompanying drawing.
Accompanying drawing is the structure principle chart of present embodiment, and wherein Fig. 1 is a front view, and Fig. 2 and Fig. 3 are respectively A-A cutaway view and the B-B cutaway view of Fig. 1, and Fig. 4 is the C-C cutaway view of direction shown in Figure 2.
With reference to accompanying drawing, the halliard wheel assembly is made up of the gear wheel (6) of halliard wheel shaft (10), band nut, lifting rope sheave (11), back-up ring (12), brake drum (7), tripping spring (3), friction plate (8,9), the halliard (2) of band screw rod.The all coaxial kink of each part of halliard wheel assembly is on halliard wheel shaft (10).If by the winding direction of halliard shown in Figure 4 (2), the rotation direction of gear wheel (6) inner nut and lifting rope sheave (10) right-hand member screw rod should be left hand direction.When halliard (2) is subjected to curtain together with the pulling force of curtain rod arm weight, affect lifting rope sheave (11) (Fig. 2 sees from right to left, down with) rotation clockwise.Left-handed screw thread makes gear wheel (6) to left movement, thereby lifting rope sheave (11) and gear wheel (6) are clamped friction plate (8,9), brake drum (7).The left-handed rotation direction of braking spring (3) just in time can limit brake drum (7) the clockwise direction rotation of this moment.Thereby realized braking, the curtain rod arm of going up can not glide because of deadweight.When the rotation of gear wheel (6) inhour, left-handed screw thread can make gear wheel (6) and lifting rope sheave (11) hold brake drum (7), friction plate (8,9) tighter.But this moment, left-handed tripping spring (3) can not limit the inhour rotation of brake drum (7), thus lifting rope sheave (11) just rotate with gear wheel (6) inhour, thereby rolling halliard (2) is finished the vertical motion of curtain rod arm.When gear wheel turned clockwise, left-handed screw thread made gear wheel (6) leave lifting rope sheave (11) and moves right and unclamped brake drum (7).Halliard (2) is under the effect of curtain rod arm deadweight, and traction lifting rope sheave (11) is followed gear wheel and turned clockwise, and finishes the down maneuver of curtain rod arm.When not having load on the halliard (2), if because frictional force, lifting rope sheave (11) does not turn clockwise with gear wheel (6), then can not move right when running into back-up ring (12) when gear wheel (6) moves right again, and can drive halliard wheel (11) by left-handed screw thread yet and turn clockwise.Thereby emit halliard (2).
Opening and closing the rope sheave assembly is made up of the switching rope sheave (25), tension wheel shaft (23), regulating wheel (19), extension spring (17,21), sleeve pipe (16,22) and the switching rope (20) that open and close sheave shaft (24), band gear.The axis of regulating wheel (19) and switching rope sheave (25) is the α (see figure 3) at angle, and the value of α is 2～5 °.Open and close rope and be subjected to the guiding of regulating wheel, can be from first grooving that opens and closes rope sheave around to second grooving, from second grooving around to the 3rd grooving.Make and open and close the frictional force traction that rope is subjected to a plurality of groovings.The length of this mechanism traction rope is unlimited, so can adapt to the needs of different curtain width.Tension wheel shaft (23) is contained in the strip hole (5A, 1C) on the frame.There is extension spring (17,21) to move to leaving the direction that opens and closes rope sheave (25) by sleeve pipe (16,22) pulling tension wheel shaft (23).Thereby can be in use, tensioning all the time opens and closes rope (20), makes it and open and close rope sheave (25) to keep the required frictional force of draw-back curtain.
The wind assembly connects spring (26) by doubly-linked gear shaft (14), doubly-linked gear bush (13), crank handle (15) and positioning ball and forms.Doubly-linked gear bush (13) endoporus is shaped on two grooves, and groove and positioning ball connect spring (26) and cooperate, can produce the doubly-linked gear about two metastable positions.Crank handle (15) is (UD direction among Fig. 2) when pulling out to the right, and doubly-linked gear bush (13) cogs (13A) and gear wheel (6) engagement.Shake crank handle (15) clockwise and just drive the rotation of gear wheel (6) inhour, thus rolling halliard (2).Inhour is shaken crank handle (15) and is just driven gear wheel (6) and turn clockwise, thereby emits halliard (2).Finish the rising and the down maneuver of curtain rod arm respectively.Crank handle (15) is (DC direction among Fig. 2) when pushing left, the gear (13B) on the doubly-linked gear bush (13) and open and close the gears engaged that rope sheave (25) is gone up left end.Clockwise and inhour is shaken crank handle (15), just can drive to open and close rope sheave (25) inhour and turn clockwise, thereby traction switching rope (20) moves back and forth, and finishes the on-off action of curtain.
Frame by frame header board (5), frame after plate (1) and some pillars (4,18 ...) form.Tripping spring (3) is hooked on the pillar (4).Extension spring (14,21) is hooked on the pillar (18).The pulling force of the extension spring of tripping spring (3) (14,21) forms seal force system by frame, can not be delivered to the frame outside.Be shaped on the plate after the frame for the hole (7A, 7B) that usefulness is installed.Be shaped on corresponding breach on the frame header board, use for holding spanner.
The utility model can not only make curtain open and close, and can also make the curtain rod arm lifting, have novel structure, simple, volume is little, self-lock ability is strong, characteristics such as safe and reliable, easy to operate.
