Abstract

The utility model aims to overcome the defects of the prior art, and provides a novel hinge which is not easy to deform, has an uneasy dropping cheese head and does not need lubricant. Two bearings are respectively arranged between shaft holes of two hinge leafs; each bearing is composed of a shell bearing, a nonmetal gasket and a metal gasket; and the nonmetal gasket is pressed into the cavity of the shell bearing by the shell bearing and the metal gasket. The hinge has the advantages that the metal gasket and the nonmetal gasket are combined in the shell bearing, the two bearings generate certain resistance to the hinge during the turning over process under the action of the elasticity of nonmetal material, and have silencing effect to achieve the goal for replacing lubricant. With a one-piece loose core adopted, the hinge has higher bearing capacity. The loose core is matched with the cheese head in an interference fit mode, and the cheese head does not directly contact the hinge to generate friction during the turning over process of the hinge to prevent the cheese head from being rubbed by an external force resulting in deformation and dropping.

Description

A kind of hinge

Technical field

The utility model relates to a kind of hinge.

Background technology

The hinge of prior art, generally by two leaf of hinge, loose core, tack forms, wherein loosing core is straight-bar type, two end cap is with tack, whole axle core is three stage structure, loose core and leaf of hinge between gap packing lubrication oil.In the process of using, the joint portion easy deformation of leaf of hinge and tack causes tack loosening even come off, and has the hidden danger on safe.In addition because the rotation of hinge, the space of loosing core with leaf of hinge increases, and the lubrication oil of filling in use overflows the black powder grease easily and influences attractive in appearance.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, a kind of supporting capacity height, tack difficult drop-off is provided and need not to use the novel hinge of lubrication oil.

For achieving the above object, the utility model is taked following technical scheme:

A kind of hinge comprises two leaf of hinge, looses core and tack; Connection hole and axis hole on each leaf of hinge; Loose core pass the axis hole of two leaf of hinge after, be connected with tack; Between two leaf of hinge axis holes, respectively establish a bearing; Described bearing is made up of cartridge housing, non-metallic gasket and metallic gasket, and metallic gasket and non-metallic gasket are pressed in the cavity of cartridge housing.

Close more smooth and easyly for hinge is turned over, and more durable, can take following measure:

Use loosing core of isometric hinge, as main shaft, tack assembles by interference fit with loosing core, and prevents that from use there is the possibility that drops in tack.Described non-metallic gasket is the material that nylon spacer or rubber sheet gasket etc. have noise reduction and low-friction coefficient.

Described cartridge housing is selected the higher steel of intensity for use.

The beneficial effects of the utility model are: metallic gasket and non-metallic gasket are combined in the cartridge housing, and two bearings make hinge have certain resistance sense in the process of stirring by the elasticity of nonmetals, also have erasure effect simultaneously.To reach the purpose that substitutes lubrication oil.Owing to adopt integral type to loose core, the ability of accepting of hinge be improved.The assembling of loosing core with tack is an interference fit, simultaneously tack hinge stir in the process not directly and hinge rubs, avoided tack to be subjected to external force friction, distortion and the phenomenon that comes off.

Description of drawings

Fig. 1 is the principle assumption diagram of the utility model embodiment.

Description of reference numerals: 1-is loosed core; The 2-spindle nose; The 3-blind hole; The axis hole of the outer leaf of hinge of 4a-; The axis hole of the outer leaf of hinge of 4b-; The 5a-bearing; The 5b-bearing; The axis hole of leaf of hinge in the 6-; 7-tack; The 8-cartridge housing; The 9-nylon spacer; 10-steel pad.

The specific embodiment

Below in conjunction with drawings and Examples content of the present invention is described further.

As shown in Figure 1,1 the end of loosing core has a spindle nose 2, and the other end has a blind hole 3.The 1 axis hole 4a that passes outer leaf of hinge successively of loosing core, bearing 5a, the axis hole 6 of interior leaf of hinge, bearing 5b, behind the axis hole 4b of outer leaf of hinge, its blind hole 3 is connected with tack 7 interference fit.Bearing 5a, bearing 5b are made up of steel cartridge housing 8, nylon spacer 9, steel pad 10.Nylon spacer 9 is put in the cavity of cartridge housing 8, again steel pad 10 is placed on the top of nylon spacer 9 and can makes bearing 5a, bearing 5b.The height of the cavity of bearing 5a, bearing 5b adds the thickness sum of steel pad 10 less than nylon spacer 9 greater than the thickness of nylon spacer 9.Bearing 5a and bearing 5b install for symmetry at the installation direction of loosing core on 1.

What this manual was enumerated is better embodiment of the present utility model only, and all equivalent technologies conversion of being done under operating principle of the present utility model and thinking all are considered as protection domain of the present utility model.
