Abstract

The utility model relates to a rotating shaft structure which comprises a fixing part, at least a fixed friction plate and a pivot part; the fixing part is provided with a contact piece; the contact piece is provided with a shaft hole in the axial direction; a plurality of joint holes are arranged at appropriate positions on the surfaces of both sides of the contact piece; the fixed friction plate is adjacent to the side surface of the contact piece; a pole hole and at least a joint part are respectively arranged on positions which correspond to the shaft hole and the joint holes; the joint parts are jointed with the joint holes, so that the fixed friction plate is fixedly connected with the side surface of the contact piece; a shaft lever extends in the axial direction of the pivot part; and after the shaft lever passes through the shaft hole of the contact piece, the pole holes of the fixed friction plates, at least a rotating friction plate and at least an elastic body, and the free end of the shaft lever is jointed with a sealing part on one end, to form the rotating shaft structure. Because at least one side surface of the contact piece of the fixing part is jointed with a fixed friction plate, the defects of the traditional contact piece that the surface is coarse and the levelness is poor because of forming by turning, so the wear is large, and the levelness of the surface of the contact piece is poor after the stopping part is punched are solved, and the service life of the rotating shaft structure is improved.

Description

Turning shaft structure

Technical field

The utility model is relevant a kind of turning shaft structure, refers in particular to a kind of turning shaft structure of at least one lateral junction unification of contact disk fixed friction sheet of fixed block.

Background technique

Press the consumption electronic products of tool flip, such as portable computer, e-dictionary, portable type video-audio playing device and cover-lifting type mobile phone ... etc., basically, be that main part is placed Lower Half, and be connected the folding that cover body part be can be with respect to main part by the cover body part of the turning shaft structure and the first half.Therefore, rotating shaft is also for determining a big essential factor of above-mentioned electronic product quality.

In fact, series type turning shaft structure with axial rub is an example, be to be connected with cover body part by a pivot member, one axostylus axostyle is hubbed at one is fixed in the fixed block of main part, and further be connected in series at least one elastomer, and with this axostylus axostyle front end in conjunction with an end sealing, anticreep nut for example, so that this elastomer is formed an axial pressure, make the surface of contact of this fixed block and pivot member form friction torsion, and make this pivot member have the function of stagnating the location with respect to fixed block.And be to make the main part of aforementioned electronic product and the function that cover body part has automatic blocking, therefore, relevant dealer increases by a cam member of being made up of a positioning piece and a revolving part in turning shaft structure, the recess that is oppositely arranged by the mating face of this locating piece and revolving part and the butt joint of protuberance, make both in a predetermined angle, have the function of automatic blocking.

Yet making flow process by the aforementioned fixation part, it roughly can be divided into two kinds of forms, one is to utilize metal sheet to be bent into L shaped support, perhaps form the fixing column of erect configuration in the turning mode, this fixing column below has a column joint, so that be intercalated in the default slot of the main part of electronic product, locked with screw again; The top then forms a sheet rubbing surface, because this sheet rubbing surface system is by the turning moulding, and comparatively coarse, flatness is not good, thus produce bigger abrasion when forming direct friction with adjacent friction member, so that shorten the working life of rotating shaft.

Moreover, this rubbing surface is for providing the restriction of folding angle, tend to a surface therein and go out the blocked part of projection, this measure is except that increasing the degree of difficulty of producing, the also uncontrollable rubbing surface of going out the blocked part still can be kept preferable flatness, and this also is a big essential factor that influences the working life of rotating shaft.
