Abstract

The utility model relates to a hinge, comprising a door leaf blade, a door frame blade and a core shaft, wherein the middle of the door leaf blade is provided with a long sleeve; two sides of the door frame blade are respectively provided with a short sleeve; the long sleeve and the two short sleeves are connected in series by the core shaft; each of two parts where the long sleeve and the short sleeves are in contact is provided with a plane bearing; each of the ratio of the width of the core shaft to the width of the door leaf blade and the ratio of the width of the core shaft to the width of the door frame blade is 2:5. The hinge has the beneficial effects that as the sleeve of the door leaf blade is changed into a middle through body structure, the processing is simple and convenient, and the stress is uniform; the diameter of the core shaft is increased, so that the hinge has a better stress ability and a longer service life.

Description

A kind of hinge

Technical field

The utility model relates to a kind of hinge.

Background technology

Common other hinge for door and window (Fig. 4) great majority of the prior art are that the blade that has the blade of three sleeve pipes and have two sleeve pipes coordinates and packs mandrel into and use, in the time of switching door, two middle sleeve pipe machining accuracies cannot ensure, the easy unbalance stress of contact surface between the two, produce friction, the easy torsional deformation of hinge after using, and gap is larger, not attractive in appearance; The width of the mandrel of existing common door window hinge is all less with the ratio great majority of the width of blade, is approximately 1.5:5, in the time that the weight of door and window is heavier, because axle diameter is less, just easily occurs distortion like this.

Utility model content

The purpose of this utility model is to provide a kind of hinge, to overcome currently available technology above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of hinge, comprise door leaf blade, doorframe blade and mandrel, the centre of described door leaf blade is provided with a long sleeve pipe, the both sides of doorframe blade are respectively provided with respectively a short sleeve, described long sleeve pipe and two short sleeves are connected in series by mandrel, and two contact positions of described long sleeve pipe and short sleeve are equipped with plane bearing.

Further, described door leaf blade and doorframe blade are equipped with some screw holes.

Further, the two ends of described mandrel are equipped with gear cap.

Further, the width of described mandrel is 2:5 with the ratio of the width of door leaf blade.

Further, the width of described mandrel is 2:5 with the ratio of the width of doorframe blade.

The beneficial effects of the utility model are: the structure of entire body in the middle of the sleeve of door leaf blade changes into, processing is simple, stressed even, easy to process, adds the diameter of macro-axis core, makes the stress-bearing capability of hinge better, longer service life.

Detailed description of the invention

As Figure 1-3, a kind of hinge described in the utility model embodiment, comprise door leaf blade 1, doorframe blade 2 and mandrel 3, the centre of described door leaf blade 1 is provided with a long sleeve pipe 4, the both sides of doorframe blade 2 are respectively provided with respectively a short sleeve 5, described long sleeve pipe 4 and two short sleeves 5 are connected in series by mandrel 3, and two contact positions of described long sleeve pipe 4 and short sleeve 5 are equipped with plane bearing 6; Described door leaf blade 1 and doorframe blade 2 are equipped with some screw holes 7; The two ends of described mandrel 3 are provided with gear cap 8; The width of described mandrel 3 is 2:5 with the width of door leaf blade 1 and the width of described mandrel 3 with the ratio of the width of doorframe blade 2.

In the utility model embodiment, integral material is preferably Q235 steel plate, 7 strokes of whirlpools of screw hole, install and check with the examination of M6 major part screw, hinge integral surface is smooth, without defects such as burr scuffings, when installation, first door leaf blade 1 and doorframe blade 2 are put well by shown position, between contact both sides face, left gap, and then pack plane bearing 6 into, then mandrel 3 is penetrated in long sleeve pipe 4, short sleeve 5 and plane bearing 6, finally install gear cap 8 at mandrel 3 two ends, the major part screw alignment screw hole 7 of getting M6, is installed to hinge on doorframe and door leaf again.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
