Description
Technical field:
The present invention relates to a kind of opening and closing device of curtain, particularly a kind of curtain rod arm.
Technical background:
The kind of electrically driven curtain has tens kinds in the domestic and international market at present, divide according to the kind of drive, mainly by four classes:
The rope pulley transmission; The linear electric motors transmission; Synchronous belt drive: rolling screw transmission.Respectively there are pluses and minuses in every kind of different kind of drive on performance, structure and price.Various different structures as the screw drive mode of tool potentiality also constantly are applied in the curtain transmission.By analyzing existing several worm drive structure, still remain further to be improved to invent.As:
1. one kind is the screw curtain rod arm, and its principle is: by the positive and negative rotation of screw rod, drive to be set on and draw circular nut or Curtain ring move left and right.As the patent No. is that 86209502 the Chinese utility model patent " spiral automatic shutter window shade arrangement " and the patent No. are that 90224991.6 Chinese utility model patent " spiral window curtain holder " is exactly this design.
Advantage is: screw rod is brachymemma very easily, is convenient to be assemblied on the window of different in width.
Shortcoming is: in the latter's the scheme, all Curtain rings all are set on the screw rod, and all wt of cord all has screw rod to bear, and the suffered driving force of screw rod is big; In the former scheme, Curtain ring is set on the polished rod, and one connects a collar nut on first Curtain ring, and with this collar nut and be screwed onto on the polished rod parallel with polished rod, this design has been provided with the screw rod and the polished rod that plays the load-bearing effect of gearing respectively, most weight of cloth is born by polished rod, thereby reduced the driving force when screw rod rotates.But Curtain ring and its wear between the screw rod that is spirally connected and remain sliding friction, and frictional force is bigger, and noise is also bigger.
2. the curtain rod arm of another kind of helical spring structure formula, last a kind of improvement that has.Having adopted the helical spring transmission principle, used helical spring to cooperate with rolling bearing with traction seat and reached the transmission purpose, is that 1132104.0 Chinese invention patent " a kind of spiral window curtain holder " is exactly this structure as publication number.
Advantage is: noise obviously reduces, and spring brachymemma arbitrarily can be applied to the window of different in width easily.
Shortcoming is: 1. be that the bearing outside that a traction holding capacity is rolled is plastics, and be single point supporting that after metal spring contacted for a long time, plastic casing also can produce wearing and tearing earlier and influence service life, it is not to be pure rolling fully that transmission has the sliding friction composition; 2. be that spring itself is softer, transmission is unreliable, because the elasticity of spring itself exists than mistake when cutting length, spring need be elongated and could load onto the jump ring location at two ends, so the spring state of the art uniformity of different product just there are differences during production.3. be behind manual draw-back curtain, cross the external diameter of static spring owing to moving sliding sleeve and do relative slippage that left and right sides cord just can not be in symmetric position.When electric operating opened and closed like this, an end arrive when spacing to the end, and the other end just can not continue recurrence and open and close and reach complete open and-shut mode, needs reach switching fully with manual operation again the increase troublesome poeration; And the curtain switching is lateral stressed along orbital direction during manual operation, because the hand force application location is different with the trailer wagon height, so there is the casement phenomenon of closure fully.
Summary of the invention:
The present invention solves the existing in prior technology deficiency, thereby develops a kind of use lightly, and noise is low, the curtain rod arm of the hollow tubular spiral ball screw transmission of reliable in structure.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of curtain rod arm structure of hollow tubulose spiral ball screw transmission is characterized in that:
