Abstract
The utility model discloses a kind of heavy door special hinges, including embedded box, the cone bearing for supporting or being fixed in the embedded box inner cavity equipped with outer ring in the embedded box, and thering is the lower part of a rotary shaft to be inserted in the inner ring of the cone bearing, the top of the rotary shaft is fixed with one in horizontal support plate.The utility model has the advantages that：Greater weight door can be supported, and cost is relatively low, use is more convenient.
Description
Technical field
The present invention relates to hardware appliance technologies, more particularly, to a kind of heavy door special hinge.
Background technique
Hinge (or hinge) is particularly important for door.If the load-bearing capacity of hinge is poor, not only directly reduce
The service life of door, and when in use, easily there are various noises, influences the mood of user.The load-bearing energy of common hinge
Power is limited, it is difficult to meet the use needs of the biggish door of weight.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of heavy door special hinges, it has
Greater weight door can be supported by having, and cost is relatively low, use more convenient feature.
To achieve the goals above, the technical scheme adopted by the invention is that：Heavy door special hinge, including embedded box,
The cone bearing for supporting or being fixed in the embedded box inner cavity equipped with outer ring in the embedded box, and there is the lower part of a rotary shaft to insert
In the inner ring of the cone bearing, the top of the rotary shaft is fixed with one in horizontal support plate.
The rotary shaft is furnished with reduction torsion spring.
The middle part of the rotary shaft is equipped with step.
The section that the rotary shaft is located at the part of the top of the step is triangular in shape, meanwhile, one end tool of the support plate
There is the sleeve on the top for being set in the rotary shaft, the inner cavity section of the sleeve is also triangular in shape.
After adopting the above structure, the invention has the advantages that compared with the prior art,：Greater weight can be supported
Door, and cost is relatively low, use is more convenient.Heavy door special hinge of the invention is supported in the lower part of door-plate, so can prop up
Support the biggish door of weight.Meanwhile no setting is required dedicated for support door weight component, it is only necessary to can be compared with by cone bearing
The good biggish door of supported weight, to save the preparation cost.And it can be given by way of grafting between all parts
With combination, uses and assemble and is more convenient.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 1 is the front sectional view of the heavy door special hinge of the embodiment of the present invention；
Fig. 2 is the top view of support plate of the invention.
Specific embodiment
Embodiment is seen figure 1 and figure 2：Heavy door special hinge, including being embedded in the pre-buried of underground in advance when in use
Box 10.
Further say：
The cone bearing 20 for supporting or being fixed in 10 inner cavity of embedded box equipped with outer ring in the embedded box 10.Obviously, should
Biggish one end of outer ring intracavity diameter of cone bearing 20 is located above, the lesser one end of diameter is located below.For example, working as the cone
When the periphery face of the outer ring of shape bearing 20 is also cone, in the embedded box 10 can be equipped with an inner cavity upper end it is larger,
The lesser taper sheath in lower end, the outer ring of the cone bearing 20 being plugged in the taper sheath from top to bottom.Meanwhile there is a rotary shaft
30 lower part is inserted in the inner ring of the cone bearing 20, and the top of the rotary shaft 30 is fixed with one in horizontal support plate 40.It should
Several mounting holes passed through for screw can be equipped in support plate 40.In this way, one end lower surface of door-plate is fixed on the branch
The top of fagging 40, since the downward pressure that the inner ring of the cone bearing 20 is subject to is bigger, the inner ring of the cone bearing 20 and outer
The combination of circle just more closely, without the component for being used to support door-plate weight is specially arranged, greatly reduces material cost,
And the assembly and maintenance of hinge are more convenient.
Optimization：
The rotary shaft 30 is furnished with reduction torsion spring 50.In this way, being convenient for the timely reset of door-plate, further increasing the hinge makes
Convenience.
Continue to optimize：
The middle part of the rotary shaft 30 is equipped with step 31.That is, the sectional area at the middle part of the rotary shaft 30 is larger, upper and lower part
Sectional area it is smaller.The downside of the step 31 is preferably and the upper end face contact of the inner ring of the cone bearing 20.I.e., it is only necessary to will
The lower part of the rotary shaft 30 being inserted in the inner ring of the cone bearing 20 from top to bottom, it is extremely convenient and easy to repair.When
So, the inner ring of the lower part of the rotary shaft 30 and the cone bearing 20 is preferably interference either transition fit.
The section that the rotary shaft 30 is located at the part of the top of the step 31 is triangular in shape.Meanwhile the one of the support plate 40
The sleeve 41 having for being set in the top of the rotary shaft 30 is held, the inner cavity section of the sleeve 41 is also triangular in shape.I.e., it is only necessary to
By the top for being set in the rotary shaft 30 of the sleeve 41 from top to bottom, and the lower end surface of the sleeve 41 is necessarily by this
The support of rank 31.In this way, further reduced the assembly difficulty of the hinge.Certainly, the top of the sleeve 41 and the rotary shaft 30
Between preferably also for interference either transition fit.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
