Description
Technical field
The utility model is related to a kind of duplex bearing door-hinge.
Background technology
Door-hinge is mainly used between connection doorframe and door, makes door centered on door-hinge, and folding is realized with respect to doorframe.General factory
The gate door-hinge in room is fixedly mounted using loose-leaf or single bearing door-hinge, loose-leaf after a protracted use easily by loose-leaf it
Between hinge cause abrasion, or because leaf hinge connection the rigid deficiency of stator itself caused by damage, it is necessary to be arranged on body
When accumulating larger door leaf, change inconvenient；And single bearing door-hinge is in use easily because the weight of door leaf causes door-hinge
There is deformation with bearing, cause to be had some setbacks or not closed enough during switch door leaf.Therefore need to make the internal structure of door-hinge
Improve.
The content of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of duplex bearing door-hinge.
The utility model solves the technical scheme that its technical problem used：A kind of duplex bearing door-hinge, including with interior
The fixed seat in chamber, the inner chamber of the fixed seat is provided with clutch shaft bearing fixing end and second bearing fixing end, and the clutch shaft bearing is consolidated
Fixed end is arranged on the upper end of fixed seat inner chamber, and the second bearing fixing end is arranged on the lower end of fixed seat inner chamber, positioned at first
Bearing fixing end and second bearing fixing end are respectively equipped with clutch shaft bearing and second bearing, the clutch shaft bearing and second bearing it
Between be also associated with shaft core, the shaft core is through the inner chamber of fixed seat.
Wherein：The clutch shaft bearing is bigger than the diameter of second bearing.
Wherein：It is excessively to coordinate or interference fit connection between the clutch shaft bearing and clutch shaft bearing fixing end.
Wherein：It is excessively to coordinate or gap mating connection between the second bearing and second bearing fixing end.
Wherein：The bottom of the fixed seat is additionally provided with integrally formed fixed plate, and diameter is provided with positioned at fixed plate central part
The through hole smaller than second bearing, is additionally provided with installation fixing hole in the fixed plate.
Wherein：The shaft core is connected by excessively cooperation or interference fit with clutch shaft bearing, second bearing.
Wherein：One end of the shaft core is additionally provided with connecting hole.
The beneficial effects of the utility model are：Simple structure, it is easy for installation, it is respectively equipped with the top and bottom of shaft core
One bearing and second bearing, and be fixed in fixed seat, the rigidity of door-hinge is improved, and the diameter of clutch shaft bearing compares second bearing
It is big, the stress point of inverted triangle is formed between shaft core, the weight of door leaf is concentrated in shaft core, reduce the mill to bearing
Damage, extend the service life of door-hinge.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is sectional view of the present utility model.
Specific embodiment
Referring to figs. 1 to Fig. 3, a kind of duplex bearing door-hinge, including the fixed seat 1 with inner chamber, the inner chamber of the fixed seat 1 sets
There are clutch shaft bearing fixing end 2 and second bearing fixing end 3, the clutch shaft bearing fixing end 2 is arranged on the upper end of fixed seat inner chamber,
The second bearing fixing end 3 is arranged on the lower end of fixed seat inner chamber, positioned at clutch shaft bearing fixing end 2 and second bearing fixing end
3 are respectively equipped with clutch shaft bearing 4 and second bearing 5, and shaft core 6 is also associated between the clutch shaft bearing 4 and second bearing 5, described
Shaft core 6 is through the inner chamber of fixed seat.
In the utility model：The clutch shaft bearing 4 is bigger than the diameter of second bearing 5.Forming one can be by door leaf
Weight concentrates on the inverted triangle stress point in shaft core 6, improves the rigidity of door-hinge, wherein, the clutch shaft bearing 4 is consolidated with clutch shaft bearing
It is excessively to coordinate or interference fit connection between fixed end 2.Wherein, it was between the second bearing 5 and second bearing fixing end 3
Degree coordinates or gap is connected.Wherein, the bottom of the fixed seat 1 is additionally provided with integrally formed fixed plate 7, positioned at fixed plate
7 central parts are provided with the diameter through hole 8 smaller than second bearing 5, and installation fixing hole 9 is additionally provided with the fixed plate 7.Wherein, it is described
Shaft core 6 is connected by excessively cooperation or interference fit with clutch shaft bearing 4, second bearing 5.Wherein, one end of the shaft core 6 also sets
There is connecting hole 61.
Further：Door-hinge can connect the main shaft on door leaf by the connecting hole 61 in shaft core 6, and the lower end of shaft core 6 can be even
Connect power set.Doorframe is connected by installing fixing hole 9, door leaf is extended with the life-span of door-hinge.
