Abstract

The utility model discloses a gravity opening-closing door hinge. An upper location base meshes with the curve wave interface of a lower location base, the upper location base and the lower location base are arranged in a shaft sleeve, a spring is arranged between the lower location base and the bottom of a shaft sleeve barrel, and the lower location base is connected with a slot through a key. Through the above connection mode and the mode that the curve wave face is used as the stress track, the utility model provides a gravity opening-closing door hinge with the advantages of reasonable design, simple structure, not easy damage and convenient disassembly and assembly, and the gravity opening-closing door hinge can use the personal gravity of the door to open, close and position the door. The spring cause the door to have a buffered process in the open and close process of the door.

Description

Gravity opens and closes door-hinge

Technical field

The utility model relates to a kind of gravity shutter door shaft device.Particularly relate to and a kind ofly realize that by curvilinear plane the open and close of door and the gravity of location open and close door-hinge.

Background technology

At present, existing hinge kind is a lot, of many uses, and its structure all is the switching that rotated by external force to realize door around a fixing axle, and function is also more single.As adopt the pattern of two page or leaf sheets of a mandrel, the hinge of this pattern, a slice is contained in fixedly on the doorframe, another sheet is installed on the swing leaf, and the page or leaf sheet that is contained on the swing leaf rotates around bearing pin, plays the effect of a switching, the hinge of this pattern, after switching, movable page or leaf sheet can't be positioned at door on the position of people's needs, because this type of hinge does not have the function of elastic force door-hinge.The elastic force door-hinge that other has glass door to use, design is complicated, cost an arm and a leg, install and keep in repair shortcoming such as inconvenience.

Summary of the invention

The purpose of this utility model is in order to address this problem, and the gravity that a kind of reasonable in design, simple in structure, not fragile, easy accessibility is provided and can uses door self realizes that the open and close of door and the novel gravity of location open and close door-hinge.

For achieving the above object, the utility model gravity opens and closes door-hinge and comprises positioning seat 1, following positioning seat 2; The described side of being, the end end body of going up positioning seat 1, the other end are to be the curve wavy surface at the cylindrical end contouring; Described positioning seat 2 cylinder inner wall base steps down are provided with the cross section curve wavy surface, and in the cylinder of positioning seat 2, last positioning seat 1 intermeshed the profile side of the being body of following positioning seat 2 with following positioning seat 2 contact surfaces under last positioning seat 1 was packed into.

Described positioning seat 2 other ends down are provided with the spring bayonet socket, have gathering sill 6 on symmetry both sides, following positioning seat 2 outsides; Shape is a cylindrical shape in the described axle sleeve 3, at the bottom of tube, be provided with spring base, sleeve lining symmetry both sides and be provided with feather key 5, one end of spring 4 is contained in down in positioning seat 2 Spring Cards, the other end of spring 4 is contained on the spring base at the bottom of 3 on the axle sleeve, following positioning seat 2 is contained in the cylinder of axle sleeve 3, feather key 5 is meshing with each other the profile side of the being body of axle sleeve 3 with gathering sill 6.

In sum, the utility model has the advantages that: reasonably utilize the gravity of door, in the process that promotes door, door is subjected to the effect of external force, makes between its potential energy and the gravity, changes on curved surface, realize the open and close of door and the function of location, spring makes door that a process of buffering be arranged when opening and closing.
