Description

A kind of hinge assembly

Technical field

The utility model relates to hinge fields, and in particular to a kind of hinge assembly.

Background technique

Hinge is a kind of articulation piece of door and window common in daily life, is mainly used for the moving process of door and window, common Hinge is all made of metal material and is made, and hinge is directly rotatablely connected with hinge axis, if hinge is not used for a long time, Hinge or hinge axis may can get rusty, and lead to occur rust staining between hinge and hinge axis, occur in rotation process abnormal sound or Person can not normal rotation carry out door and window folding work, if hinge frequency of use is excessively high, it is also possible to will appear hinge and hinge Cooperation loosen, axis runout causes door and window that can not be normally carried out folding, and hinge will be scrapped, and can not reuse, simultaneously Hinge mounting hole on door, window and doorframe is because of the reason of dismantling, it is difficult to reuse, so that door, window and doorframe receive It is difficult to the damage restored, firmness is affected.

Summary of the invention

The technical problems to be solved in the utility model is to overcome present technological deficiency, provides a kind of hinge and hinge Axis is not in a kind of hinge assembly of abnormal sound, easy to install, quick detachable, easy replacement part of damage during rotation.

The technical solution of the utility model is to provide a kind of hinge assembly, including the first hinge, the second hinge and hinge Axis, the first hinge include first connecting portion, and the second hinge includes second connecting portion, it is characterised in that: and it further include two axle sleeves, one A axle sleeve and first connecting portion circumferentially limit grafting, and rotate and be socketed with one end of hinge axis, another described axle sleeve with Second connecting portion circumferentially limit grafting, and rotate and be socketed with the other end of hinge axis, the axle sleeve is plastic part.

The utility model has the following beneficial effects: axle sleeve is placed on rotation axis and is connected with first using high-intensitive wear-resistant plastic Between socket part, second connecting portion, during rotation, the friction between metal and plastics is not in easy sound, and rubbed It does not need to add lubricating oil as friction between metal and could preferably be rotated in journey, while metal is in installation and removal It is identical as ready-made hinge in the process, as long as the mistake of position installing and dismounting and installation is directed at axis in corresponding process mesoporous Journey unlike metalwork damages, will integrally be scrapped in maintenance, and under the cooperation of plastics and metalwork, the damage of plastic part Wound can be faster than metalwork, so in most cases all only axle sleeve damages when hinge assembly damages, and first Hinge, the second hinge and hinge axis are not in damage, as long as maintenance can be completed in replacement axle sleeve, are not all needed in overall process Hinge assembly is disassembled from door or window or doorframe, still guarantees the first contract of hinge assembly and door, window, doorframe It closes, fit system will not be had an impact.

As a kind of improvement of the utility model, the periphery wall of the axle sleeve is circumferentially at least one retraction slot, passes through The improvement, the inner wall and hinge axis of axle sleeve are clearance fits, and hinge axis can be easily inserted into axle sleeve, the outer wall of axle sleeve It is interference fit with first connecting portion, second connecting portion, when axle sleeve is inserted into first connecting portion or second connecting portion, retraction slot It can be shunk according to the degree of interference, ensure that the abundant cooperation of axle sleeve Yu first connecting portion, second connecting portion, and will not be because Axle sleeve is caused to wear during the installation process for interference fit, simultaneously as the contraction of retraction slot, can also make sleeve lining The radius in hole is reduced, and the matching relationship of the inner wall and hinge axis that make axle sleeve becomes transition fit by clearance fit or interference is matched It closes, keeps the cooperation of axle sleeve and hinge axis closer, will not occur the case where shaking after installation is complete.If the inner wall of axle sleeve with Hinge axis is rotatablely connected in the form of interference fit after installation is complete, after hinge assembly repeatedly rotates, because of retraction slot Gap, in the case where not wearing axle sleeve, the inner wall of axle sleeve can expand outwardly deformation, make interference fit can toward transition fit become Change.

As a kind of improvement of the utility model, the axis of the inner hole wall of the axle sleeve and the axis of periphery wall be not conllinear, By the improvement, the relative rotation of hinge assembly first connecting portion and second connecting portion during rotation can be made to belong to partially Heart rotation, it can door and window is made more quickly, gap can also to be less prone to after merging with door and window in merging process.

As a kind of improvement of the utility model, first hinge be equipped with First Transition section, the First Transition section with The periphery wall of first connecting portion is tangent, and second hinge is equipped with the second changeover portion, second changeover portion and second connecting portion Periphery wall it is tangent, when the First Transition section is coplanar with the second changeover portion, the axis collinear of the outer wall of two axle sleeves leads to The improvement is crossed, guarantees the relative position of the first hinge and the second hinge, speed during when door and window merges is avoided the occurrence of and becomes Slowly, gap is bigger.

As a kind of improvement of the utility model, two axle sleeves offset, and the position that the axle sleeve offsets is equipped with flange, By the improvement, it can be equipped with flange between first connecting portion and second connecting portion, first connecting portion is avoided to connect with second There is abnormal sound in rotation in socket part contact.

As a kind of improvement of the utility model, the flange is equipped with Installation Mark, passes through the improvement, it is ensured that The accuracy of first connecting portion and second connecting portion installation site, avoids the occurrence of mistake.

As a kind of improvement of the utility model, the flange is equipped at least one disassembly slot far from the side in the face that offsets, By the improvement, in the case where needing replacing axle sleeve, quickly the axle sleeve under interference fit can be taken apart.

As a kind of improvement of the utility model, the retraction slot and disassembly slot do not have junction, can by the improvement Occur the case where thin-walled in one direction to avoid axle sleeve, and stress concentration is easy to damage at this.

As a kind of improvement of the utility model, the circumferential direction position limiting structure refers to the first connecting portion or second Limiting slot is equipped in the connecting hole of interconnecting piece, the periphery wall of the axle sleeve is equipped with the protrusion circumferentially limited with limiting slot, passes through The improvement, it is ensured that it is circumferential to limit the preparatory of angle, avoid installation from deviation occur.

As a kind of improvement of the utility model, the bottom end of the axle sleeve is equipped with gas vent, by the improvement, because May may require that in installation process and first axle sleeve and first connecting portion, second connecting portion are installed, after again by axle sleeve and hinge The case where axis is installed, at this time can be to avoid when hinge axis be inserted into axle sleeve, and axle sleeve can not be discharged in the gas in axle sleeve, difficult Hinge axis to be adequately inserted in axle sleeve.
