Abstract

The utility model relates to an improved pivot mechanism which comprises a first body, a second body, two elastic components and two moment arm resistant bodies, wherein, the first body is provided with a first ear part; the second body is provided with a second ear part; the first ear part is arranged on the side of the second ear part by striding; the second body is rotatablely and pivotally arranged on one end of the first body; both ends of each elastic component respectively apply force on the first body and the second body; the elastic component is a torsion spring; a sleeve is arranged on an inner edge of the elastic component; the moment arm resistant bodies are connected on the first body; one ends of the two moment arm resistant bodies are pivotally arranged on the two elastic components. Therefore, applied force generated by the elastic components can be rightly dispersed on the first body by the moment arm resistant bodies, thereby the fact that structure of the first body is destroyed by inappropriate stress due to concentration of the applied force of the elastic components on a certain position of the first body is effectively avoided.

Description

The hinge mechanism of improvement

Technical field

The utility model relates to a kind of hinge mechanism of improvement, refers to a kind of being installed in relative rotation between two articles especially, so that the mechanism of stable rotating position to be provided.

Background technique

Hinge mechanism is widely used in each field, be generally used for the connection between the two articles, and make two articles can do respect to one another rotatablely moving, to carry out switch motion, as has furniture of door-plate etc., moreover, can add the assembly that some have specific function in hinge mechanism, so that hinge mechanism further in rotatablely moving, have various such as: automatically recurrence, multistage or non-section type location and bear function such as heavy burden can further be applied to hinge mechanism the adjustment location of devices such as display device thus.

Yet, often be equiped with elastic component in the hinge mechanism and make functions such as flowing mode and adjustment location to derive other, but, if elastic component is misapplication, also can cause assembly to bear improper stress simultaneously, cause take place that body structure destroys, start not really or produce unnecessary abrasion between parts, and then shorten the working life of product.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, proposes a kind of hinge mechanism of improvement, avoids hinge because of the installing elastic component, and bears improper stress rupture.

For reaching above-mentioned purpose, the utility model provides a kind of hinge mechanism of improvement, comprising: one first body; One second body, it is hubbed at an end of this first body rotationally; Two elastic components, its two ends force in respectively on this first body and this second body; And two drag arm bodies, it is connected on this first body, and this two drags arm body, one end is hubbed on this two elastic component.

The utlity model has following beneficial effect: the active force that this elastic component produced can be scattered in rightly on this first body by this drag arm body, with the force localization of avoiding this elastic component effectively in certain of this first body, cause this first body structure of excessive improper stress rupture, or cause start not reach the unnecessary abrasion phenomenon of generation between parts really.

For enabling further to understand feature of the present utility model and technology contents, see also following relevant detailed description of the present utility model and accompanying drawing, yet appended graphic only for reference and explanation usefulness is not to be used for the utility model is limited.
