Description
Technical field
The utility model relates to hinge technical field, particularly relates to a kind of closed type hinge structure.
Background technology
Hinge is modal a kind of hardware in people's daily life.Hinge has another name called hinge, and formal name is hinge, normal composition two foldings, is attached article two parts and can makes it movable parts, being widely used in the installation of door, window etc.Existing hinge sealing performance is bad, and in the product institute that some dusts are larger, external dust particle easily enters into hinge inside, along with the accumulation of dust, easily affects the flexibility of hinge.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of closed type hinge structure, simple and reasonable, good seal performance, and external dust particle not easily enters into hinge inside.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of closed type hinge structure, comprise: upper hinge and lower hinge, described upper hinge comprises a Upper shaft sleeve, described lower hinge comprises a Lower shaft sleeve, described Upper shaft sleeve and Lower shaft sleeve are flexibly connected by a mandrel, described mandrel is applied in Upper shaft sleeve and Lower shaft sleeve is inner, the middle part of described mandrel has an evagination pad, described evagination pad and mandrel are integral type structure, the upper surface of described evagination pad and soffit are equipped with polytetrafluorethylecoatings coatings, the upper end of described Upper shaft sleeve has a upper seal head, the lower end of described Lower shaft sleeve has a lower seal head.
In the utility model preferred embodiment, described upper seal head is threaded with between Upper shaft sleeve.
In the utility model preferred embodiment, described lower seal head is threaded with between Lower shaft sleeve.
In the utility model preferred embodiment, described upper hinge adopts aluminium alloys to make, and described lower hinge adopts aluminium alloys to make.
The beneficial effects of the utility model are: the utility model closed type hinge structure, simple and reasonable, and good seal performance, external dust particle not easily enters into hinge inside.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model closed type hinge structure one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, upper hinge, and 2, lower hinge, 3, Upper shaft sleeve, 4, Lower shaft sleeve, 5, mandrel, 6, evagination pad, 7, upper seal head, 8, lower seal head.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of closed type hinge structure, comprise: upper hinge 1 and lower hinge 2, described upper hinge 1 comprises a Upper shaft sleeve 3, described lower hinge 2 comprises a Lower shaft sleeve 4, described Upper shaft sleeve 3 and Lower shaft sleeve 4 are flexibly connected by a mandrel 5, described mandrel 5 is applied in Upper shaft sleeve and Lower shaft sleeve is inner, the middle part of described mandrel 5 has an evagination pad 6, described evagination pad 6 is integral type structure with mandrel, the upper surface of described evagination pad 6 and soffit are equipped with polytetrafluorethylecoatings coatings, more flexible when Upper shaft sleeve and Lower shaft sleeve are rotated, can not noise be produced.
The upper end of described Upper shaft sleeve 3 has a upper seal head 7, and the lower end of described Lower shaft sleeve 4 has a lower seal head 8, and the setting of described upper seal head 7 and lower seal head 8 can avoid external dust particle to enter into hinge inside.
Preferably, described upper seal head 7 is threaded with between Upper shaft sleeve, and described lower seal head 8 is threaded with between Lower shaft sleeve, good sealing effect.
Described upper hinge adopts aluminium alloys to make, and described lower hinge adopts aluminium alloys to make.
The utility model closed type hinge structure, simple and reasonable, good seal performance, external dust particle not easily enters into hinge inside.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
