Abstract
A kind of duplex bearing two-orbit pulley, including housing, it is characterised in that: have twice sliding-rail groove on the coat, the both ends of housing are separately installed with bearing.Its advantage is that being able to maintain the degree of balance of fan after being installed to door and window fan, increase the weight that pulley is born, can be better than the load bearing effect of general single track list sliding slot pulley, it pushes and pulls more smooth.
Description
Technical field
The utility model relates to the attachmentes for sliding or being promoted wing, belong to door and window hardware field, espespecially a kind of twin shaft
Hold two-orbit pulley.
Background technique
Door and window trolley is generally mounted to door and window bottom or top, what door and window was equipped with above or below sash by pulley
It is slided on sliding rail.The existing door and window bottom or the pulley at top of being installed on is single-bearing list slideway structure, the cunning of this structure in the market
Wheel often will lead to that left and right center of gravity is inconsistent after being installed on sliding door, cause the door leaf inclination, push-and-pull to have some setbacks, light load-bearing lacks
It falls into.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of duplex bearing two-orbit pulleys.It is intended to
Solve the inclination of door leaf caused by the door and window trolley of the prior art, push-and-pull has some setbacks, the defect of light load-bearing.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of duplex bearing two-orbit pulley is provided,
Including housing, it is characterised in that: have twice sliding-rail groove on the coat, the both ends of housing are separately installed with bearing.
The housing is integral structure, and material is metal material, and there are the recess for bearing merging in the housing two sides.
Pulley spindle is installed in brearing bore, the outer ring of bearing can drive housing to rotate when use.
The beneficial effects of the utility model are: being able to maintain the degree of balance of fan after the utility model is installed to door and window fan, increase
The weight for adding pulley to bear, can be better than the load bearing effect of general single track list sliding slot pulley, pushes and pulls more smooth.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is that the utility model installs and uses one of status diagram.
Fig. 3 is that the utility model installs and uses the two of status diagram.
In figure: 10 being a kind of duplex bearing two-orbit pulley of the utility model, 20 be sliding door and window sectional, 30 be U-shaped material
Track, 40 are sliding door and window frame section.
In a kind of duplex bearing two-orbit pulley 10 of the utility model: 11 being housing, 12 be sliding-rail groove, 13 be bearing.
Specific embodiment
Referring to attached drawing, a kind of duplex bearing two-orbit pulley of the utility model, including housing 11, it is characterised in that: in housing
On have twice sliding-rail groove 12, the both ends of housing are separately installed with bearing 13.
In the embodiments of the present invention, the housing 11 is integral structure, and material is metal material, the housing
There are the recess for bearing merging in two sides.
Pulley spindle is installed in brearing bore, the outer ring of bearing 13 can drive housing 11 to rotate when use.
