One end of the auxiliary shaft is also provided with a flat fixing sheet, and the other end has a shaft hole; a concave ring groove is arranged in the shaft hole, and the hole wall at the bottom is provided with a radial through hole. The front section of a tightening bolt has screw threads, the middle section has an oblique conical surface, and the rear section has a horizontal cross section for the force application of rotation. The utility model is used for notebook computers.
Description
The utility model relates to the armature apparatus of notebook computer.
Existing armature apparatus is as shown in Figure 7: it is made up of a main shaft 10, a countershaft 20 and a packing ring 30, main shaft 10 1 ends have the taper axle sleeve 101 of band opening, axle sleeve 101 outer rims of this hollow have screw thread 102, packing ring 30 inboard ends have inclined-plane 301, end has the screw thread 302 that matches with screw thread 102 in addition, countershaft 20 outer rims have oil guide groove 201, packing ring 30 is set in axle sleeve 101 outsides, countershaft 20 is threaded onto in the axle sleeve 101, mat packing ring 30 is adjusted the compressing program of facing countershaft 20 in the axle sleeve 101, reaches the elasticity when regulating 10,20 pivots of major-minor axle.But this structure, axle sleeve 101 is two and is held on the countershaft, clamping compressing power is even inadequately, add the influence of oil guide groove 201 oil plants, can make to produce between the major- minor axle 10,20 and come off, make the distance of 103,202 of major and minor axle 10,20 both sides fixed orifices wayward, need the distance of adjustment separately to install again during assembling, very inconvenient; And packing ring 30 easily rotates because of touching, and causes the elasticity of 10,20 pivots of major-minor axle to become inaccurate.
The purpose of this utility model provides a kind of elasticity that major and minor axle is pivoted and keeps the suitable pivot device that can adjust pressing degree arbitrarily.
The purpose of this utility model is achieved in that the pivot device that can adjust pressing degree arbitrarily, and it is made up of a main shaft, a countershaft and a clamping bolt; It is characterized in that: this main shaft one end is made as the stator of flat, and end is made as the axle sleeve of a hollow form in addition, and axle sleeve has internal thread, and the terminal outer rim of axle sleeve forms the bail of a ridge convex, offers profile groove on the wall; Countershaft one end also is made as the stator of flat, and end has an axis hole in addition, and concave ring groove is arranged in the axis hole, and the bottom hole wall is provided with a radial direction through hole; The clamping bolt leading portion is provided with screw thread, there is a scalene cone in the stage casing, and back segment is provided with for pulling the side grain that revolves the application of force, and clamping bolt revolves a part of screw thread of lock goes forward side by side in the main shaft axle sleeve, make main shaft together with the axis hole of clamping bolt wedging in the lump, and the bail of main shaft is held in the concave ring groove of countershaft in countershaft.
Above-mentioned design utilizes the clamping bolt of this structure, promptly can adjust major and minor axle pressure drag to each other, and can be positioned an anglec of rotation arbitrarily, and accurate positioning is reliable, has reached to make major and minor between centers pressing degree keep suitable effect, and can adjust arbitrarily.
Be described further again below by accompanying drawing, embodiment.
