Abstract

The utility model relates to a double-shaft hinge joint, which solves the problems that the prior art has a plurality of parts, complex assembly and high manufacturing cost. The utility model comprises a first hinge joint carriage and a hinge joint shaft connected with the first hinge joint, wherein one end of a second hinge joint carriage is covered around the hinge joint shaft, and at least one spacing pad and disc spring are covered around the hinge joint shaft. The utility model is characterized in that the center of end portion of the hinge joint shaft is provided with a notch, and the flanging punched by the notch keeps the spacing pad and the disc spring on the hinge joint shaft. As the utility model adopts the structure, the parts are reduced greatly, the distortion distance is stable, and the smooth property and the stability is good; as the parts are reduced, the making, handing and assembling procedures are reduced, thereby improving production efficiency, reducing cost and improving competitive power.

Description

Biaxial hinge

Technical field

The utility model relates to a kind of hinge means, specifically to having a kind of improvement of biaxial hinge now.

Background technology

Existing hinge means is widely used on the article such as laptop computer, mobile phone, refrigerator-freezer, duplicator, makes this article folding slyness, and can keep the opening of certain angle when using, and article are not had impact, prolongs article application life.In the market competition that is growing more intense, the client is more and more higher to the requirement of hinge, wishes that quality height, the price of hinge is low.Existing a kind of biaxial hinge 100 as shown in Figure 8, it comprises hinge axis 130, is with first hinge bracket 110 and second hinge bracket 120 on hinge axis 130, and a plurality of separation pad 140, dish spring 150, control pad 160, is fixedly formed by nut 170.The torque that it is taken place by dish spring 150 is kept the open mode of second hinge bracket 120, and noise and wearing and tearing when dwindling switch motion.But also there are some shortcoming and defect in this hinge, the one because the component that this hinge uses are more, therefore make, required very expensive during assembling, make that the cost of hinge is very high; The 2nd, owing to use nut 170 fixing, so nut 170 torque instability when loosening, tighten state, in addition for attaching nut 170, on hinge axis 130, also to form screw portion, therefore make this hinge cost improve greatly.

Summary of the invention

The utility model be for solve the component that prior art exists many, make, the assembling complexity, manufacturing cost high-technology problem.

In order to solve the problems of the technologies described above, the utility model comprises first hinge bracket and coupled hinge axis, one end of second hinge bracket is enclosed within on the hinge axis, also be with more than one separation pad and dish spring on the hinge axis, it is characterized in that: the center, end at hinge axis has groove, the flange that stamps out by groove with separation pad and dish spring backstop on hinge axis.

In the utility model, also have following feature: be with separation pad, second hinge bracket, separation pad, symmetrical a pair of dish spring and separation pad on the described hinge axis successively, the flange that the groove at center, hinge axis end stamps out with above-mentioned parts backstop on hinge axis.

Also have following feature in the utility model: the cross section of described hinge axis is " D " shape face, and described separation pad center has " D " shape through hole identical with the hinge axis shape of cross section.

In order to make the hinge action slyness, in the utility model, also has following feature: have oil-way on the one or both sides of the described separation pad and second hinge bracket.

The utlity model has following advantage and good effect: because the utility model has adopted said structure, used component obviously reduce, and torque is stable, can guarantee the slyness and the soundness of hinge action; In addition,, therefore improved production efficiency widely, reduced cost, improved competitiveness because the minimizing of component makes making, processing, assembling procedure also obviously reduce.
