Abstract
The utility model discloses a universal pulley seat used in clothes pole pulling rope, consisting of a bearing seat, a pulley and a bottom seat. The bearing seat takes a half ball shape. The top of the half ball of the bearing seat is movably connected with a supporting seat by a connecting shaft through a plane bearing. A bearing pulley is arranged inside the supporting seat though a pulley rotating shaft. Compared with the prior art, the utility model provides a universal pulley seat with the advantages of simple structure, exposure pulley, and no limit of the rope out direction.
Description
The utility model relates to a kind of pulley base, especially a kind of universal pulley base that is used for stay cord on the clothes-horse.
Be used for the pulley base that stay cord turns in the existing clothes-horse, generally form by pulley and bearing, pulley is fixed on the bearing, the pulley base of this spline structure can only be suitable for the single stay cord that turns to, turn to many maybe need change the time as stay cord, need or reinstall with a plurality of pulleys, complex structure uses inconvenient.Pulley base that some can multidirectional rotation is arranged owing to be subjected to the influence of cover body and rope hole, make structure complicated more, make rope outlet direction restricted, rotate dumb.
The purpose of this utility model is to improve the shortcoming that said structure exists, and a kind of simple in structure, pulley exposes, rope outlet direction is not subjected to any restriction universal pulley base is provided.
The purpose of this utility model is achieved in that it is made up of bearing, pulley and base, described bearing is a hemispherical, be connected with supporting seat by connecting axle by plane bearing at its hemisphere top, by the pulley rotating shaft pulley be installed in the described supporting seat.
The two ends symmetry of described bearing has the screw hole fixed screw and is connected with base by screw hole, and base is installed in the concave station of bearing, and base is provided with base fixing hole and bearing fixing hole.
Described pulley is two, is installed in the supporting seat side by side by the pulley rotating shaft.
Described pulley is a bearing pulley.
Described supporting seat is " U " shape.
Described base is a cross, wherein has on the two ends of base fixing hole curvedly, makes plane, base fixing hole place be higher than plane, bearing fixing hole place.
Because the utility model has adopted said structure, compared with prior art has the following advantages: simple in structure, easy for installation; Assembly pulley directly exposes, and makes the clothes-horse stay cord can be unrestricted, adapts to the needs of different directions; The pulley bearing pulley, its detent force is good, and carrying is big, and sliding effect is good, and resistance is little, and is not fragile, and overcome the prior art rotation and adopted spherical rotation, though rotatable, rotate ineffectively, easy to wear, bearing capacity is low, shortcomings such as positioning performance difference.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a base schematic diagram of the present utility model.
Among the figure: 1. bearing; 2. supporting seat; 3. pulley; 4. pulley rotating shaft; 5. plane bearing; 6. fixed screw; 7. base; 8. screw hole; 9. connecting axle; 10. base fixing hole; 11. bearing fixing hole; 12. concave station.
Bearing 1 is a hemispherical, inside is provided with concave station 12, be connected with supporting seat 2 by connecting axle 9 by plane bearing at its hemisphere top, supporting seat 2 is " U " shape structure, in supporting seat 2, two bearing pulleies 3 are installed side by side by pulley rotating shaft 4, the supporting seat 2 of Yin Ben device is rotatably connected on the bearing 1 by connecting axle 9, so supporting seat 2 can rotate by any direction, make the stay cord of clothes-horse not be subjected to the restriction of rope hole and bearing, expose outside because of pulley again, and adopt bearing pulley universally to rotate, adapt to the needs of different directions.Detent force is good, and carrying is big, and sliding effect is good, and resistance is little, and is not fragile.The two ends symmetry of bearing 1 has screw hole 8, fixed screw 6 is connected with base 7 by screw hole 8, base 7 is installed in the concave station 12 of bearing 1, base 7 is provided with base fixing hole 10 and bearing fixing hole 11, base 7 is a cross, wherein have on the two ends of base fixing hole 10 curvedly, make plane, base fixing hole 10 place be higher than plane, bearing fixing hole 11 place, the top edge that has guaranteed base fixing hole 10 and bearing 1 when installing like this is in a plane.The inside of bearing 1 can make hollow both economical with materials, reduces weight again.When supporting seat 2 is connected with bearing 1 by connecting axle 9, in order to guarantee to have installed a plane bearing 5 additional for to supporting seat 2 rotations flexibly between supporting seat 2 and bearing 1, make sliding effect desirable more, plane bearing 5 also can change packing ring or pad into as required.
