Abstract
The utility model relates to a pulley aid. The utility model is characterized in that: the utility model comprises a wheel hub and a slide aid ring arranged on the wheel hub, the slide aid ring is provided with an annular groove matched with a sliding track. The utility model has the advantages of simple structure, low cost, long service life, flexible slide, handiness and so on.
Description
(1) technical field
The utility model relates to a kind of pulley that helps, and relates in particular to a kind of pulley that helps of slide door or window.
(2) background technology
The existing pulley that helps generally is to adopt bearing, though it is flexible, light to slide, and complex structure, cost height.
(3) summary of the invention
The purpose of this utility model provides that a kind of slip is flexible, light, simple in structure, and cost is low helps pulley.
In order to achieve the above object, the utility model is achieved in that and it is characterized in that: it comprises wheel hub and is located at the slipping ring that helps on the wheel hub, and is provided with the cannelure that matches with slide rail on the slipping ring helping.
Of the present utility modelly further be improved to, wheel hub comprises three layers, and two is outer and be located at intermediate layer between two skins; Be provided with axle sleeve on two skins, the intermediate layer is provided with the hole, so that axle passes; Two outer field diameters are greater than the diameter of internal layer, thereby form the spill mouth, so as better with help slipping ring to fix.Aforementioned three layers are connected as a single entity by pin; Two outside layers that also can three layers is a metal, and its two ends are crooked in opposite directions, and spot welding is fixed; The two ends of two metal levels also can connect by fastener.The surface of the outstanding wheel hub of axle sleeve.Help slipping ring can adopt engineering plastics or rubber to make.
The utility model compared with prior art has following advantage:
1, simple in structure, cost is low;
2, long service life, it is flexible, light to slide.
(4) description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A sectional view of a kind of embodiment of Fig. 1;
Fig. 3 is the A-A sectional view of a kind of embodiment of Fig. 1.
(5) specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, 2, it comprises wheel hub 3 and is located at and help slipping ring 1 on the wheel hub, is provided with the cannelure 11 that matches with slide rail on the slipping ring 1 helping; Help slipping ring 1 can adopt engineering plastics or rubber to make.Wheel hub 3 comprises three layers, two outer 31 and be located at intermediate layer 32 between two skins; On two skins, be provided with axle sleeve 311, the surface of axle sleeve 311 outstanding wheel hubs 3, the intermediate layer is provided with hole 321, so that axle passes; Intermediate layer 32 can be that metal level also can be non-metallic layer, for example iron plate or rubber; The diameter of two skins 31 is greater than the diameter in intermediate layer 32, thereby formation spill mouth helps in the slipping ring 1 so that snap in, and better fixedlys connected with helping slipping ring; Three layers are connected as a single entity by pin 2.As shown in Figure 3, above-mentioned three layers outside 31 is two-layer to be metal, and its two ends are crooked in opposite directions, and spot welding is fixed; Outside two metal levels also can connect by fastener.
