Abstract
The utility model discloses a rotation shaft structure capable of adjusting the torsion. According to the rotation shaft structure, a cylindrical boss is arranged on a male shaft, a high-carbon steel plate is stamped to form a main body which can be matched with the boss, and the outer circumference surface of the main body is provided with a notch part which extends along the axial direction of the main body and penetrates through the both axial end faces of the main body. When the male shaft is in interference fit with a monopack, the rotation shaft structure can be used to adjust the torsion according to installation conditions; and the adjustment process is simple and practical, the connection of the rotation shaft is stable and reliable and the rotation shaft has high practicability.
Description
Technical field
the utility model relates to the adjustable turning shaft structure of a kind of torsion.
Background technique
In
folding electronic equipment, like notebook computer, mobile phone, DV vidicon camera etc., the closure or openness between its screen and the apparatus body are generally realized through rotating shaft is set.Generally speaking; On the link position place of screen and apparatus body one of which, be fixedly connected public axle is set; Fixedly install on another and can cooperate the female axle that is rotated with this public affairs axle; Public axle need be provided with suitable torsion with the female joint of matching, and realizes closure or openness thereby make the user can easily screen be rotated with respect to apparatus body in use.Existing public axle generally obtains through turning when manufacturing with female axle; Adopt interference fit between public axle and the female axle; The fit tolerance of public axle and female axle need be set according to the size of torsion, and the part product accuracy of manufacturing of public axle and female axle requires high, and torsion is difficult adjusts.
Summary of the invention
The purpose of
the utility model provides the adjustable turning shaft structure of a kind of torsion, thereby can be when rotating shaft is installed adjusts the torsion of rotating shaft according to the installation situation.
For achieving the above object, the technological scheme that the utility model adopts is:
adjustable turning shaft structure of a kind of torsion; Said turning shaft structure comprises public axle, single bag that can be connected with said public axle rotationally, and said public axle has a cylindrical shape projection; Said single cylindrical shape main body that is stamped to form by the high carbon steel steel plate that comprises; Said main body has the through hole that runs through said main body two axial end faces vertically, and said projection can insert in the said through hole ordinatedly, and said projection and said through hole employing interference fit; Have notch part on the outer peripheral surface of said main body, said notch part is along the two axial end faces that extend axially and run through said main body of said main body.
preferably, said single bag also comprises the joint that is arranged on said main body one end.
are as a kind of concrete mode of execution; One end of said main body offers diametrically is cut into two antimeric groovings with said end; And cut out a plane respectively at two link positions of said grooving and main body interfaces; Said two symmetric parts are by the lug boss of said plane excision back formation two symmetries, and said lug boss is said joint.
preferably have a plurality of annular grooves on the outer peripheral surface of said projection.
are because the utilization of technique scheme; The utility model compared with prior art has advantage: through on public axle, the cylindrical shape projection being set; And form the main body of the cylindrical shape that can match by the punching press of high carbon steel steel plate with above-mentioned projection; And has the notch part that extends axially and run through two axial end faces of this main body on the outer peripheral surface of main body along this main body; When the through hole of the projection of public axle and single bag carries out interference fit, if torsion between the two is excessive, the outer peripheral surface of main body that then can be through beaing single bag; Thereby being out of shape under the effect of percussion power, this main body make the breach of notch part become big; The elasticity of main body increases like this, and the torsion the when projection of public axle rotates in the through hole of single bag reduces, thereby making that screen and the rotation between the body of electronic equipment is more light satisfies usage requirement.This turning shaft structure can cooperate when installing the size according to installation situation adjustment torsion at public axle with single bag, and adjustment process is simple, and this rotating shaft connection is reliable and stable, the practicability height.
Description of drawings
Accompanying drawing 1 is the exploded view of the turning shaft structure of the utility model;
accompanying drawing 2 is the constitutional diagram of the turning shaft structure of the utility model.
Embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
referring to shown in Fig. 1-2, the adjustable turning shaft structure of a kind of torsion is used for folding-type electronic device; This rotating shaft comprises public axle 1, single bag 2 that can be connected with public axle 1 rotationally, and an end of public axle 1 has the projection 11 of cylindrical shape; Single bag 2 has the main body 21 of cylindrical shape; Main body 21 is stamped to form by the high carbon steel steel plate, and this main body 21 has the through hole that runs through 21 liang of axial end faces of this main body vertically, and projection 11 can be inserted in this through hole ordinatedly; And adopt interference fit to be connected between projection 11 and this through hole; Also have notch part 22 on the outer peripheral surface of main body 21, notch part 22 is along the two axial end faces that extend axially and run through main body 21 of main body 21, and this notch part 22 is used to increase the elasticity of main body 21.Like this when public axle 1 carries out interference fit with single bag 2; If torsion between the two is excessive; The outer peripheral surface of main body 21 that then can be through beaing single bag 2, thus the main body 21 that the high carbon steel steel plate is stamped to form is out of shape under the effect of percussion power and is made the breach of notch part 22 can become greatly, the elasticity of main body 21 increase like this; Torsion when the projection 11 of public axle 1 rotates in the through hole of single bag 2 reduces, thereby making that screen and the rotation between the body of electronic equipment is more light satisfies usage requirement.
are referring to shown in Fig. 1-2; Single bag 2 also comprises the joint that is arranged on main body 21 1 ends; In the present embodiment, this joint is achieved in that to offer diametrically on the end of main body 21 two antimeric groovings is cut in this end, and two link positions that join mutually in this grooving and main body 21 cut out a plane respectively; Like this; Above-mentioned two antimeric two end part are up and down promptly cut away by this plane and have formed 23, two lug bosses 23 of lug boss and promptly formed joint, and this joint is arranged on the apparatus body of folding-type electronic device with the screen joint or is arranged on the screen and the apparatus body connection.
are referring to shown in Figure 1; Have a plurality of annular grooves 12 on the outer peripheral surface of projection 11; When the projection 11 of public axle 1 matches with the through hole of female axle 2; Can lubricant in the annular groove 12, thus make things convenient for installations that cooperate of projection 11 and through hole, also reduce follow-up projection in use 11 and singly wrapped the wearing and tearing between 2.
