Although hinge is a kind of comparatively common frame for movement, its design feature determines joint pin must bear shearing force and moment of flexure, is very easy to make a noise because of friction between all parts simultaneously, and reality still has further room for improvement.
Heavily loaded tapered hinge of the present utility model then make use of structural improvement and overcomes the stand under load problem of hinge to a certain extent, more superior by loading capability, meet the design principle of mechanics, and the friction effectively improved between parts, running more smoothly, thus reduces the noise in product operation process.
General butterfly hinge have employed the joint pin directly structure that arrange interspersed with video disc 1, although structure is more simple, but there is larger friction between joint pin and video disc 1, and constantly rub in the process that also operates at butterfly hinge of the part contacted with each other between video disc 1 and video disc 1, thus greatly have impact on the smooth degree of hinge running, easily send the noise of squeak.And the columniform structures shape of joint pin it does not have supporting capacity completely to video disc 1 in the axial direction, this directly increases the contact friction between video disc 1 and video disc 1.
Heavily loaded tapered hinge of the present utility model have employed special tapered hinge pin 2, and the contour structures of taper can provide component axially, makes the installation firm stable more of video disc 1, effectively prevents the friction between video disc 1 and video disc 1.And between tapered hinge pin 2 and video disc 1, add that hardness is moderate, the nylon guide 3 of smooth texture, improve the friction between parts, to avoid between tapered hinge pin 2 with video disc 1 direct contacts.
As preferably, the group portion 8 of described nylon guide 3 is provided with the oil filler point 9 radially extended, and the end face in group portion 8 and the inwall of guide main body 7 are provided with the oil duct 10 be communicated with oil filler point 9.
Also there is friction the end in the end of the connector 6 of video disc 1 and the group portion 8 of nylon guide 3, in order to further reduce friction factor between the two, improving smooth degree, preferably adding lubrication oil; In like manner, as the same between the pin-and-hole of nylon guide 3 and tapered hinge pin 2.In use procedure, only need to instill a small amount of lubrication oil to oil filler point 9, namely lubrication oil flow into oil duct 10 through oil filler point 9, and by uniform application in the process of product operation, between the connector 6 and the group portion 8 of nylon guide 3 of video disc 1, form the oil film of layer between the pin-and-hole of nylon guide 3 and tapered hinge pin 2, it is to stronger lubricant effect.And this design makes the maintenance of product very convenient, even if do not dismantle any parts can carry out oiling work yet.
