Abstract

The utility model relates to an anti-sinking noiseless hinge, which relates to the rotating component of the metal anti-theft door. According to the defects of the existing hinge which has large noise, easy abrasion, and the frequent sinking of the door plate, the utility model is provided with a liner between a small shaft and a sleeve cylinder on the basis of the hinge composed of a hinge, the small shaft, a hinge plate, and the sleeve cylinder, and a thrust bearing is arranged between the sleeve cylinder and the hinge. Accordingly, the noise is removed; the sedimentation can be prevented; the pollution can be alleviated; the wear-resistant performance is good; the service life is long, and the rotation is portable. The anti-sinking noiseless hinge is suitable for the positive effects of the industrial production.

Description

A kind of anti-heavy noiseless hinge

The utility model relates to a kind of door-plate rotatable parts, particularly relates to metal anti-theft door-plate rotatable parts.

At present, how the rotatable parts of metal anti-theft door-plate are closed by hinge, flap, and little axle and sleeve pipe are formed, and after use a period of time, the heavier and air pollution because of door-plate often is between little axle and sleeve pipe; Between sleeve pipe and hinge close, be prone to wearing and tearing, corrosion, the former causes noise, and the latter causes door-plate to sink, and directly causes the switch difficulty.Real is not ideal.

In order to overcome above-mentioned weak point, the purpose of this utility model is that a kind of elimination noise will be provided, and prevents sedimentation, pollution abatement, and wear-resisting lengthening the life rotated light anti-heavy noiseless hinge.

The purpose of this utility model is to realize like this, promptly at the hinge that closes by hinge, flap, little axle and sleeve are formed, between its little axle and sleeve pipe, be provided with and be used to reduce friction, be provided with thrust bearing between lining, sleeve and the hinge of elimination noise closes, wherein lining is made by soft metal or nonmetals.

Owing between little axle and sleeve, establish into lining; Hinge close and sleeve pipe between establish into thrust bearing, thereby realized the elimination noise, prevent sedimentation, pollution abatement, wear-resisting lengthening the life rotated light technique effect.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a kind of anti-heavy noiseless hinge part section structural representation

Fig. 2 is Fig. 1 plan structure schematic diagram

Fig. 3 is Fig. 1 left side TV structure schematic diagram

By a kind of as can be known anti-heavy noiseless hinge of Fig. 1,2,3, be to close (1), little axle (2), flap (3) by hinge and becoming with it by mechanical means on the hinge basis that the sleeve (4) of one forms, do not have lining (5) between its little axle (2) and sleeve (4), sleeve (4) and hinge close does not have thrust bearing (6) between (1).Wherein flap (3) has installing hole (3-1), lining (5) available copper material, and nylon material is made, and thrust bearing (6) can be thrust bearing, thus the anti-heavy noiseless hinge after improving has been realized the application's goal of the invention.

Claims (2)

1, a kind of hinge that contains closes (1), little axle (2), flap (3), the anti-heavy noiseless hinge of sleeve (4), it is characterized in that being provided with between little axle (2) and the sleeve (4) and be used to reduce friction, the lining (5) of elimination noise, sleeve (4) and hinge close and are provided with thrust bearing (6) between (1).

2, a kind of anti-heavy noiseless hinge according to claim 1 is characterized in that said lining (5) made by soft metal or nonmetals.
