Abstract
The utility model discloses a wire rope idler wheel bracket for an external sun-shading roller shutter. The wire rope idler wheel bracket comprises a bracket body, wherein an idler wheel is flexibly connected to the bracket body through a pin shaft; a slot, the diameter of which is matched with the diameter of a wire rope, is arranged on the periphery of the idler wheel; a second pin shaft is arranged above the idler wheel on the bracket body; a baffle wheel is sleeved on the second pin shaft; the second pin shaft and the baffle wheel are in clearance fit with each other; and a rotatable needle bearing is arranged between the pin shaft and the idler wheel. The slot, the diameter of which is matched with the diameter of the wire rope, is arranged on the periphery of the idler wheel, so that the wire rope is limited in the slot on the periphery of the idler wheel all the time in the up-and-down rolling process of a roller shutter. When a shaking handle is operated, the wire rope is smoothly and stably coiled and released and is free from shifting and jumping out of the slot. Under the limitation of the baffle wheel, the wire rope is further prevented from jumping out of the slot, so that the use is safe and reliable. The rotatable needle bearing is arranged between the pin shaft and the idler wheel, so that the operation of a lifting device by hand becomes labor-saving, quick and convenient.
Description
Technical field
The utility model relates to a kind of external sunshade roller shutter wire rope rolling wheel support, belongs to external sunshade roller shutter technical field.
Background technology
The curtain face oscilaltion scrolling of external sunshade roller shutter adopts electronic and manual two kinds of modes.Electronic by the direct scrolling realization of tube shaped electric machine, manually then there are many mechanisms such as rocking bar, stay cord, drawstring and wire rope crank to form manual hoisting device spool is rotated, drive the folding and unfolding up and down of roller shutter face.Because the folding and unfolding of wire rope crank is easy for installation, intensity of steel wire height, wear-resisting, durable, the cost performance advantages of higher is used more and more widely.
And the rolling wheel support that adopts in the present manual hoisting device, intensity is low, structure is owed rationally, the card rope often occurs, and steel wire is jumped the position from groove, and steel wire is easy to wear, and frictional resistance is big, pulling is hard, rotates difficulty when making crank folding and unfolding steel wire, if undue force, promptly damage manual hoisting device, the repair rate height occurs, the reclamation work amount is big, also makes troubles to the user.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can make wire rope be difficult for to jump the position from groove, steel wire is durable in use, pulling is convenient, rotate external sunshade roller shutter wire rope rolling wheel support smoothly.
The technical solution of the utility model is:
A kind of external sunshade roller shutter wire rope rolling wheel support comprises stake body, is connected with roller by bearing pin on the stake body, and the periphery of roller is provided with the groove suitable with wirerope diameter.
The top of stake body upper roller is provided with second bearing pin, is set with gear wheel on second bearing pin, matched in clearance between second bearing pin and the gear wheel.
Be provided with rotating needle bearing between bearing pin and the roller.
Beneficial effect: the utility model is owing to be provided with the groove suitable with wirerope diameter on the periphery of roller, make wire rope at the roller shutter face up and down in the scrolling process, all the time be limited in the groove on the roller periphery, when handgrip is shaken in operation, the wire rope folding and unfolding is smooth and easy, stable, can not be offset, beat from groove, even the stressed deviation in driction of wire rope wheel groove center wire rope can not occur from groove or phenomenon such as blocked yet, thereby make the roller shutter folding and unfolding laborsaving; When shedding pulling force, during the wire rope bounce-back, because the shelves wheel is spacing, wire rope can not jump out of roller groove yet, and is safe and reliable; Be provided with rotating needle bearing between bearing pin and the roller, can make manual lifting device easily laborsaving, quick and easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of roller 4 among Fig. 1.
Among the figure: 1-stake body, 2-shelves wheel, 3-wire rope, 4-roller, 5-bearing pin, 5A-second bearing pin, 6-needle bearing, 7-groove.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of external sunshade roller shutter wire rope rolling wheel support comprises stake body 1, is connected with roller 4 by bearing pin 5 on the stake body 1, and the periphery of roller 4 is provided with and the suitable groove 7 of wire rope 3 diameters.
The top of stake body 1 upper roller 4 is provided with the second bearing pin 5A, is set with matched in clearance between gear wheel 2, the second bearing pin 5A and the gear wheel 2 on the second bearing pin 5A.
Be provided with rotating needle bearing 6 between bearing pin 5 and the roller 4.
Have on roller 4 peripheries and the mutually suitable groove 7 of employed wire rope 3 diameters, leave rational gap between groove depth, the wide and wire rope 3, to satisfy wire rope 3 positive and negative smooth and easy rotations, be slidingly matched between the second bearing pin 5A and the shelves wheel 2, stressed back shelves wheel 2 can rotate on second bearing pin 5 like a cork.
