Abstract
The utility model designs an adjusting ohm of a shutter pull rope style which comprises two shells-a left and a right shell and a base used to fix the two shells, wherein, a gearing is arranged in the two shells which comprises a reel winding the pull ropes, in the center of the axis of the reel a small screw is fixed which is connected with a big screw by two meshing gears, the bid screw is meshed with a helical gear, wherein, two grooves are arranged on the reel device. The utility model has the advantages of that, compared with the present adjusting ohm, a buffering big screw is added to increase the driving path and do the same work by less power, so that while pulling the shutter ohm(especially a heavy type shutter), more strength will be saved when compared with the normal ohm of a pull rope style, moreover, two grooves are arranged on the reel device to make two pull ropes of different directions separating mutually from each other which can avoid overlap of the two pull ropes when rotating, thus making the pull more smoothly.
Description
Technical field
The utility model relates to a kind of shutter accessory, and specifically a kind of drawing cord for louver window formula is adjusted the improvement technology of ohm.
Background technology
Existing adjustment ohm is to be made of coiling synthetic fibre, big screw rod, gear etc.It is by pulling stay cord on the reel, making reel drive the big screw rod that is fixed together with it rotates, big screw rod driven gear, gear again rotation is passed to iron bar and on fixator, control ladder band dislocation motion relatively up and down at last, thereby make the blade upset, reach the purpose of black out.Therefore, the pulling force during our stay cord is exactly the driving source that makes the blade upset.Obviously, when having when having the shutter of higher density than multiple-blade or blade itself, pulling spurs stay cord with regard to handy bigger pulling force.
The utility model content
Laborsaving when the technical problems to be solved in the utility model provides a kind of use, spur smoothly the drawing cord for louver window formula and adjust ohm.
According to above-mentioned technical requirements, the utility model is realized by the following technical solutions:
A kind of drawing cord for louver window formula is adjusted ohm, comprise left and right two shells and the base of fixing two shells, in two shells transmission device is installed, described transmission device comprises that one twines the reel of stay cord, the reel axle center is fixed with a small screw, small screw also is connected with a big screw rod by two meshed gears, is engaged with a helical gear on the big screw rod.
As further improvement of these options, above-mentioned reel is provided with two conduits.
Simultaneously, on left and right shell, have the fixedly fixing hole of helical gear axis; Be provided with the groove of slightly larger in diameter in the left and right shell in small screw, big screw rod axis.
Advantage of the present utility model is: increased the big screw rod of a buffering with respect to the existing ohm of adjusting, utilize the big screw rod of buffering to increase drive path, make and can do equal merit with littler power, thus more laborsaving than using common dragline type ohm when drawing shutter ohm (especially heavy sun blind); In addition, reel is provided with two conduits, and the stay cord of two different directions is isolated mutually, two stay cords phenomenon that overlaps in the time of avoiding rotating, thus make pulling more smooth and easy.
Description of drawings
Accompanying drawing 1 is the utility model embodiment decomposing state structural representation; Accompanying drawing 2 is present embodiment combination back structural representation.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, present embodiment mainly comprises left shell 7, right casing 2, base 1 and is installed on runner assembly in the cavity that is formed by left shell 7, right casing 2 that left shell 7, right casing 2 are fixed on the base 1 by rivet 8.
Runner assembly comprises a reel 6, and reel 6 is provided with two conduits 61,62, is used for twining respectively two rightabout stay cords, can prevent during use that the stay cord on two directions from overlapping each other.Be fixed with a small screw 4 at reel 6 axis, the two can realize synchronous rotation.Small screw 4 middle part diameters are less, intert in by left shell 7 further groove 71, the right casing 2 further groove 21 combination axle sleeves that form, and are fixed with a gear 41 at small screw 4 other ends.Runner assembly also comprises a big screw rod 5, and an end of big screw rod 5 is fixed with a gear 51, and gear 51 is meshed with gear 41, and big screw rod 5 axis are fixed on by left shell 7 further groove 72, right casing 2 further groove 22 in conjunction with in the axle sleeve that forms.Above big screw rod 5, also be engaged with a helical gear 3, helical gear 3 is perpendicular with big screw rod 5 axle center, has the fixedly circular hole 73,23 of helical gear 3 axis on left shell 7, right casing 2, and helical gear 3 axis are empty, are convenient to connect external structure.
During work, rotate by the stay cord pulling reel 6 that is wrapped on the reel 6, reel 6 drives small screw 4 rotations, small screw 4 drives big screw rod 5 by gear 41, gear 51 and rotates, big screw rod 5 drives helical gear 3 again and rotates, and helical gear 3 drives the mechanism that directly connects curtain again makes whole curtain blade realize upset.
