Abstract
The utility model discloses a heavy door hinge, which comprises a fixed hinge, a hinge shaft, a movable hinge and a friction reduction device. The fixed hinge is fixed on a door frame and provided with a supporting blind hole, one end of the hinge shaft is fixed in the supporting blind hole, the movable hinge is fixed on a door leaf and provided with a rotating blind hole, the rotating blind hole is sleeved at the other end of the hinge shaft, and the friction reduction device for reducing rotation friction force is mounted between the movable hinge and the hinge shaft. The door hinge not only leads an entrance door to be opened and closed flexibly but is durable.
Description
Technical field
The utility model relates to a kind of door hinge, relates in particular to a kind of heavy door hinge.
Background technology
In large-scale warehouse, the workshop used the door all be heavier, bigger large-scale door, it is fixed on the doorframe by door hinge, door hinge generally all is that fixed page or leaf and moving page or leaf are hinged by hinge axis, but because door is heavier, the force rate that fixed page or leaf and moving page or leaf are subjected to is bigger, and the switching at gate is very not smooth just, back of long duration is more obvious owing to many-sided reason such as get rusty opens and closes not smooth problem, and also easy care not of door hinge.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of heavy door hinge is provided, and this door hinge not only makes the gate open and close flexibly, and durable in use.
For solving the problems of the technologies described above, the technical solution of the utility model is: heavy door hinge comprises: be used for fixing the fixed page or leaf on doorframe, described fixed page or leaf is provided with one and supports blind hole; Hinge axis, an end of described hinge axis are fixed in the described support blind hole; Be used for fixing the moving page or leaf on door leaf, described moving page or leaf is provided with one and rotates blind hole, and described rotation blind hole is set in the other end of described hinge axis; Between described moving page or leaf and the hinge axis antifriction apparatus that is used to reduce rotation friction is installed.
Wherein, described antifriction apparatus comprises an end thrust ball, and described end thrust ball is installed in the described rotation blind hole and with described hinge axis upper end and leans.
Wherein, described antifriction apparatus comprises a rolling bearing, and described rolling bearing is installed on the described hinge axis and embeds in the described rotation blind hole.
As a kind of improvement, described moving page or leaf upper end is provided with and rotates the oiling passage that blind hole communicates.
After having adopted technique scheme, effect of the present utility model is: owing between described moving page or leaf and the hinge axis antifriction apparatus that is used to reduce rotation friction is installed, therefore, the gate is when opening and closing, antifriction apparatus reduces with regard to the frictional force that makes hinge axis and rotate between the blind hole, reduced frictional dissipation, thereby it is smooth and easy flexibly that the gate is opened and closed, door hinge is durable in use.
Again because described antifriction apparatus comprises an end thrust ball, described end thrust ball is installed in the described rotation blind hole and with described hinge axis upper end and leans, therefore, the hinge axis upper end leans the weight that end thrust ball upper support whole door, when the gate opens and closes, rolling friction between hinge axis upper end and the end thrust ball is very little, thereby it is smooth and easy flexibly that the gate is opened and closed.
Again because described antifriction apparatus comprises a rolling bearing, described rolling bearing is installed on the described hinge axis and embeds in the described rotation blind hole, therefore, rotation blind hole on the moving page or leaf not with the hinge axis friction, sliding friction between original hinge axis and the rotation blind hole has been changed into the rolling friction of rolling bearing, just greatly reduce frictional force, it is smooth and easy flexibly that the gate is opened and closed, and door hinge is durable in use.
Again owing to being provided with on the described moving page or leaf and rotating the oiling passage that blind hole communicates, therefore just can carry out oil injecting lubricating to end thrust ball and the rolling bearing that rotates in the blind hole by the oiling passage, reduced frictional force, it is smooth and easy flexibly that the gate is opened and closed, convenient later maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure sectional view of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment;
In the accompanying drawing: 1. fixed page or leaf; 2. moving page or leaf; 3. support blind hole; 4. rotation blind hole; 5. installing plate; 6. welded plate; 7. hinge axis; 8. needle bearing; 9. end thrust ball; 10. oiling passage.
The specific embodiment
A kind of heavy door hinge as depicted in figs. 1 and 2, comprising: be used for fixing the fixed page or leaf 1 on doorframe, described fixed page or leaf 1 comprises a welded plate 6 that is used to be welded on the doorframe, and described fixed page or leaf 1 is provided with one and supports blind hole 3; Hinge axis 7, an end of described hinge axis 7 are fixed in the described support blind hole 3; Be used for fixing the moving page or leaf 2 on door leaf, described moving page or leaf 2 comprises an installing plate 5 that is used for fixing on door leaf, on door leaf, described moving page or leaf 2 is provided with one and rotates blind hole 4 by bolt for described installing plate 5, and described rotation blind hole 4 is set in the other end of described hinge axis 7; Also be equipped with between described moving page or leaf 2 and the hinge axis 7 and be used to make described hinge axis 7 and rotate the antifriction apparatus that frictional force reduces between the blind hole 4.Described antifriction apparatus comprises a rolling bearing and a smooth end thrust ball 9, described rolling bearing is a needle bearing 8, described rolling bearing is installed on the described hinge axis 7 and embeds in the described rotation blind hole 4, described end thrust ball 9 is installed in the described rotation blind hole 4 and with described hinge axis 7 upper ends and leans, and described moving page or leaf 2 upper ends are provided with and rotate the oiling path 10 that blind hole 4 communicates.
Operating principle of the present utility model is: when opening and closing at the gate, moving page or leaf 2 rotates with respect to fixed page or leaf 1, because the existence of needle bearing 8, rotating blind hole 4 does not rub with hinge axis 7, sliding friction between original hinge axis 7 and the rotation blind hole 4 has been changed into the rolling friction of rolling bearing, and hinge axis 7 upper ends also not with the cecum friction of rotating blind hole 4, but be transformed into rolling friction between hinge axis 7 upper ends and the end thrust ball 9, so just greatly reduce frictional force, it is smooth and easy flexibly that the gate is opened and closed, door hinge is durable in use, and when needing, can carry out oil injecting lubricating to end thrust ball 9 and the rolling bearing that rotates in the blind hole 4 by the oiling path 10, reduce frictional force, improve application life, and installing plate 5 is by bolt rather than welds mainly to be to avoid welding that the gate is caused damage, and be welded on the doorframe during welded plate 6 of fixed page or leaf 1, so relatively firmly and durable.
