Abstract
The utility model relates to a rolling-up curtain, in particular to the lift rolling curtain device, comprising a casing, rotating shaft mainsprings, ratchet wheels, friction plates, springs, etc. The utility model can ensure that the curtain stays at any position, and the operation is extremely simple and convenient.
Description
The utility model relates to overwind curtain, particularly rolling shutter lifting device.
GN87210651, the overwind curtain of CN87217538 patent disclosure.Structure is basic identical, and rolling shutter lifting device is integral with the reel structure that volume is hung curtain.One end of reel is contained on the support with its fixing end axle.Other end device has a semiaxis, with the reel installation that is rotatably assorted, is fixedly connected with support.Mounting torque spring on the semiaxis in reel.In reel ends ratchet is housed, with the notched dish cooperating on the semiaxis.When above-mentioned prior art had only ratchet to be in breach dish top, ratchet could lean on gravity fall to cooperate with breach on the breach dish, stoped that volume rotates on the reel.Because the limited amount of ratchet can not be realized curtain is rested on any position so generally be 1-3.Particularly when last volume curtain, need earlier pulling downwards, make ratchet break away from the wedge point, send on fast again or let go, make reel can realize quick rotation rapidly, so that ratchet is subjected to enough centrifugal actions, reel could rise, therefore can not ensure that once-through operation finishes curtain and rise and rest on and give allocation, so the rolling shutter lifting device structure is unsatisfactory, moment of torsion spring structure volume is big, and the life-span is short, and with the curtain reel be integral structure, inconvenience is installed, guarantee.
The purpose of this utility model provides an overwind curtain, particularly rolling shutter lifting device, can make curtain rest on any position, and is simple to operate, and convenient, accurate, structural performance is good.
The utility model includes the curtain winding up roller.Place casement, fixed support and rolling shutter lifting device on the winding up roller to constitute.There is axis hole at cord winding up roller two ends, and the one end is rotatably assorted with bearing pin on being fixed on support and connects, and the other end cooperates connection with the output revolving shaft key/pin of rolling shutter lifting device.Rolling shutter lifting device 4 is by housing, rotating shaft, handle ratchet wheel circle, handle ratchet wheel circle friction pressure ring, stage clip, and the block tongue, the block tongue that cooperate with ratchet push away spring, the clockwork spring formation.The friction pressure ring places handle ratchet wheel circle both sides, and is subjected to the stage clip effect, and the corresponding handle ratchet wheel circle of rotating shaft place has blind hole, and block tongue and block tongue push away spring arrangement in this hole, cooperate with the handle ratchet wheel circle, make the relative handle ratchet wheel circle of rotating shaft unidirectionally to rotate.Clockwork spring is inner to be fixedly connected with rotating shaft, and outer end and housing are fixed.The output that housing is stretched out in rotating shaft has key/pin.Cooperate connection with cord winding up roller end axis hole.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model rolling shutter lifting device structural representation.
Fig. 3 is Fig. 2 A-A sectional view.
Fig. 4 is Fig. 2 B-B sectional view.
Further describe the utility model in conjunction with the accompanying drawings.Curtain winding up roller 1 is microscler pipe, and there are pipe envelope and axis hole in two ends, and an end is rotatably assorted with fixed axis on the support 2 and connects, and has the output shaft of keyway and rolling shutter lifting device to be fixedly connected by pin 17 on the axis hole of the other end.Rolling shutter lifting device; Housing 5 is one cylindric, and an end has dead eye, is used to install rotating shaft 11, the end cap 14 that the other end has a usefulness screw thread to connect with housing 5.Handle ratchet wheel circle 8 is rotatable in housing 5.Friction pressure ring 9 is also fixed, or with housing 5 are one, friction pressure ring 6 does not preferably turn, cooperate (not shown) in its appearance recessing with pin on placing housing 5, but axially do not lock, clockwork spring 5 places in the clockwork spring lining 16, and clockwork spring 15 is contained in rotating shaft 11 ends, its the inner is fixedly connected with rotating shaft 11 usefulness slotted eyes, and the outer end is reinstated pin 19 with lining 16 1 and fixed with housing 5.Pin hole on the housing 5 is an axial slots, makes lining 16 can certain adjustable amount of movement arranged axially.Friction stage clip 12 places between pressure ring 6 and the clockwork spring lining 16, screws in housing 5 parts promotion lining 16 with end cap 14 and moves axially, and places the stage clip catch 13 of lining 16 sidepieces, moves the pressure of adjusting 12 pairs of frictions of stage clip pressure ring 6 with lining 16.Catch 13 and lining 16 one also can be independent parts.Support 18 is an one with housing, and also independent part is fixedly connected with screw and housing
The utility model support 2,3 and curtain box or wall mounted.The curtain of putting on cord winding up roller 1 by downward pulling volume drives winding up roller 1 rotation, and winding up roller rotates rotating shaft 11 rotations that drive rolling shutter lifting device.The rotation of rotating shaft 11 makes clockwork spring 15 rolling-in.After cord winding up roller 1 stopped operating, the rotary torque of clockwork spring 15 acted on rotating shaft 11, and handle ratchet wheel circle 8 cooperates with block tongue 7, and rotating shaft can not reverse rotation, i.e. rotating shaft 11 can only unidirectionally be rotated with respect to handle ratchet wheel circle 8, can not reverse.Because handle ratchet wheel circle 8 is subjected to the rotary torque of the frictional force effect clockwork spring 15 of stage clip 12 and friction pressure ring 6,9 that handle ratchet wheel circle 8 is arbitrarily rotated, and is provided with balance weight body/bar in the lower end of casement.The weight that counterweight (bar) adds the casement under the exhibition adds the rotary torque of the suffered frictional resistance of handle ratchet wheel circle 8 greater than clockwork spring 15 again, and handle ratchet wheel can not rotate, and it is motionless that side can rest on this position curtain.When the counterweight (bar) of the casement lower end that holds in the palm, the clockwork spring rotary torque can overcome handle ratchet wheel circle 8 suffered frictional resistance, handle ratchet wheel circle 8 rotates, rotating shaft 11 realizes counter-rotating, drive 1 counter-rotating of cord winding up roller, carry and pack up curtain, curtain rests on this position again when putting down counterweight (bar) again.Weight linear meter also works to flatten casement.
The utility model is owing to can adjust the size of handle ratchet wheel circle 8 suffered frictional resistance.The selection of counterweight (bar) weight of casement is easy to, and is that certain weight range of choice is arranged, therefore, implement easily.
The utility model structural behaviour is good, and curtain can rest on any position, and operation is extremely simple, convenient, can guarantee that once-through operation accurately locates, and does not have bump, and the rolling shutter lifting device volume is little, durable, is not integrated with the cord winding up roller, is convenient to install.
