Abstract
The utility model discloses a thrust bearing for a hinge. The thrust bearing for the hinge comprises a rotating structure which is composed of an annular dynamic ring, an annular static ring and a roll ball, an annular protective cover which is arranged outside the rotating structure in a covering mode and an annular clamping ring. The annular clamping ring is clamped between the annular dynamic ring and the annular static ring. Combined with the prior art, the thrust bearing for the hinge has the advantages that the annular clamping ring is arranged in a clamping mode, the annular clamping ring and a hinge hinged shaft are in close-fitting connection, so that the bearing is prevented from falling by accident, and thrust bearing for the hinge is practical and reliable, and meanwhile the entire structure is simple and compact, easy to manufacture, and strong in adaptability.
Description
Technical field
The utility model relates to a kind of bearing arrangement, belongs to the ball bearing technical field, refers in particular to a kind of hinge thrust bearing.
Background technology
For a long time, hinge is widely used in various door leafs field.In the prior art, hinge generally comprises upper hinge structure and the lower jaw structure that switching cooperates, and upper hinge structure and door leaf sectional material are fastenedly connected, and lower jaw structure and doorframe are fastenedly connected.To reduce wear in order making between upper hinge structure and the lower jaw structure, to reach the purpose of level and smooth rotation, generally all can between upper hinge structure and lower jaw structure, bearing be set.This class bearing device of the prior art just directly is set on the hinge of hinge; not having any fastening structure pins bearing; therefore; in actual application; often can produce a problem, namely in assembling process, particularly before being assembled into door leaf on the doorframe; the easy accidental of this class bearing device causes certain inconvenience to erection work.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of hinge thrust bearing that improves structure is provided, and this bearing forms close-fitting by ring gripping circle and hinge hinge and is connected, thus difficult drop-off.
To achieve these goals, the utility model is realized according to following technical scheme:
A kind of hinge thrust bearing includes the rotational structure that annular moving-coil, annular Jing Quan and ball consist of, the annular protecting cover that covers at the rotational structure outside, an and ring gripping circle, and described ring gripping circle is clipped between annular moving-coil and the annular quiet circle.
Further, described ring gripping circle includes flange portion and gripper section, and flange portion is clipped between annular moving-coil and the annular quiet circle, and gripper section is uniformly at intervals in the inner circumference end of flange portion.
Further, the gripper section of described ring gripping circle tilts to narrow to the bearing rotary axle center from flange portion gradually.
Further, form the closed cavity between described annular moving-coil, annular Jing Quan and the ring gripping circle flange portion three.
The utility model compared with prior art, its beneficial effect is:
The utility model has installed the ring gripping circle additional, forms close-fitting by ring gripping circle and hinge hinge and is connected, thereby avoid the bearing accidental, and is practical reliable, and overall structure is simply compact simultaneously, and easy to manufacture, applicability is strong.
In order to understand more clearly the utility model, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is package assembly schematic diagram of the present utility model.
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Fig. 3 is package assembly schematic internal view of the present utility model.
Fig. 4 is assembly structure schematic cross-section of the present utility model.
Fig. 5 is use status architecture schematic diagram of the present utility model.
The specific embodiment
Shown in Fig. 1 to 5, hinge thrust bearing described in the utility model, include the rotational structure that annular moving-coil 1, annular quiet circle 2 and ball 3 consist of, the annular protecting cover 4 that covers at the rotational structure outside, an and ring gripping circle 5, described ring gripping circle 5 is clipped between annular moving-coil 1 and the annular quiet circle 2.
Preferred version as the present embodiment, described ring gripping circle 5 includes flange portion 51 and gripper section 52, flange portion 51 is clipped between annular moving-coil 1 and the annular quiet circle 2, and gripper section 52 tilts to narrow to the bearing rotary axle center in the inner circumference end of flange portion 51 and from flange portion 51 uniformly at intervals gradually.Further, form the closed cavity D between described annular moving-coil 1, annular quiet circle 2 and ring gripping circle flange portion 51 threes, this cavity D can be preserved sliding agent, and is lubricated for ball, to reduce resistance to rolling, improves the life-span.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
Claims (4)
