Abstract
A kind of integral type two-orbit pulley, it is characterised in that：Including inner ring, rolling element, outer shroud and the double flute wheel body sequentially connected from inside to outside, the rolling element is double column structure, its centre-to-centre spacing is equal with the centre-to-centre spacing of double flute in double flute wheel body, there is rolling body support frame to can be rotationally connected rolling element between inner ring and outer shroud, end cap is installed between the inner ring and outer shroud.The combination of the inner ring, rolling element, outer shroud, rolling body support frame and end cap can be the centripetal spherical bearing of standard two-row or other double-row bearings.The double flute wheel body is plastic body.Its advantage is that after being installed to door and window fan, the degree of balance of door and window fan can be kept, increases pulley supporting power, keeps it better than the load bearing effect of general single-row single sliding slot pulley, push-and-pull is more smooth.
Description
Technical field
The utility model is related to pulley, espespecially a kind of integral type two-orbit pulley.
Background technology
The pulley that push-pull door and window uses is a kind of common Hardware fitting, is generally mounted to door and window bottom or top, door and window
The bearing part for sliding on the sliding rail being arranged above or below sash by pulley, and being used on pulley is its core part,
Can pulley be directly influenced rotary balance.The pulley for being installed on door and window bottom or top of the prior art uses standard single-row bearing
It holds and is combined with single slideway pulley, the pulley of this structure may result in left and right center of gravity after being installed on sliding door inconsistent, cause
Door leaf tilts, push-and-pull has some setbacks, the defect of light load-bearing.
Invention content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of integral type two-orbit pulleys.
Technical solution adopted by the utility model to solve its technical problems is：A kind of integral type two-orbit pulley is provided,
It is characterized in that：Including inner ring, rolling element, outer shroud and the double flute wheel body sequentially connected from inside to outside, the rolling element is biserial
Structure, centre-to-centre spacing is equal with the centre-to-centre spacing of double flute in double flute wheel body, has between inner ring and outer shroud and rolls body support frame by rolling element
It can be rotationally connected, end cap is installed between the inner ring and outer shroud.
The combination of the inner ring, rolling element, outer shroud, rolling body support frame and end cap can be the centripetal spherical bearing of standard two-row
Or other double-row bearings.
The double flute wheel body is plastic body.
The utility model has the beneficial effects that：After being installed to door and window fan, the degree of balance of door and window fan can be kept, increases pulley
Supporting power keeps it better than the load bearing effect of general single-row single sliding slot pulley, and push-and-pull is more smooth.
Description of the drawings
The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is one schematic diagram of application state of the utility model.
Fig. 3 is two schematic diagram of application state of the utility model.
In figure：10 it is load-bearing pulley under sliding door and window, 11 be inner ring, 12 be rolling element, 13 be outer shroud, 14 is rolling element branch
Frame, 15 be end cap, 16 be double flute wheel body, 20 be U-shaped material track, 30 be sliding door and window frame section, 40 be sliding door and window fan type
Material, 50 are the utility model integral type two-orbit pulley.
Specific implementation mode
Referring to attached drawing, a kind of integral type two-orbit pulley of the utility model 50, it is characterised in that：Including from inside to outside sequentially
Inner ring 11, rolling element 12, outer shroud 13 and the double flute wheel body 16 of connection, the rolling element 12 are double column structures, centre-to-centre spacing with it is double
The centre-to-centre spacing of double flute is equal in sheave body 16, has rolling body support frame 14 that rolling element 12 is rotatable between inner ring 11 and outer shroud 13
Ground links together, and end cap 15 is equipped between the inner ring 11 and outer shroud 13.
In the embodiments of the present invention, the inner ring 11, outer shroud 13, rolls body support frame 14 and end cap at rolling element 12
Combination be the centripetal spherical bearing of standard two-row.
In the embodiments of the present invention, the double flute wheel body 16 is plastic body.
