Abstract

The utility model relates to a non-section pivot shaft capable of regulating torsion. The non-section pivot shaft is composed of mutually sheathed pivot shafts, a pivot shaft sleeve and a tight ring sleeve arranged on the outer part of the pivot shaft sleeve, wherein the pivot shaft and the pivot shaft sleeve are respectively and fixedly arranged on a main machine body and a screen. A cylinder is arranged on one side of the pivot shaft. A plurality of torsion regulating sheets are arranged on the pivot shaft sleeve in an annular mode in respect to the outer part of the cylinder. A cone part is formed on the outer parts of the torsion regulating sheets in respect to the pivot shafts. A cutting plane is formed on each torsion regulating sheet in respect to the tight ring sleeve. Mutually matched cone holes are formed in the tight ring sleeve sheathed on each torsion regulating sheet. The torsion of the non-section pivot shaft is adjusted by adjusting the position of the tight ring sleeve. Thus, the screen can be definitely positioned on the required position of a user.

Description

Can adjust the no section pivot of torsion

Technical field

The utility model is a no section pivot of adjusting torsion about a kind of, refers in particular to a kind of no section pivot that is used on mobile computer or mobile phone or the desktop screen.

Background technology

Because the progress of science and technology, computing machine have become one of indispensable instrument, for the work of going out or be convenient to speech and use, mobile computer more is subjected to popular liking owing to archives material can be carried easily.

Mobile computer is in order to save the space and can be easy to carry, and most design has liftable screen and main body two major parts, but the pivot that the mat folding covers connects two parts; Mobile computer development so far, existing many research and development that are used to link the pivot of screen and main body, its purpose makes the user when use nothing more than providing mobile computer more convenient location, can arbitrarily adjust the viewing angle of screen.

So long as the people who used mobile computer is arranged, all as can be known, be provided with main body and screen in mobile computer, this screen main body relatively pivot to be opened or is closed and covers, be provided with pivot between screen and main body, pivot must will have suitable constraint degree, just can make screen pivot with respect to main body and open, and the location is provided at any time, can watch screen to make things convenient for the people;

But, its shortcoming is: pivot is after using one period time, because of screen with respect to the unlatching of main body or close frequent, can cause pivot to produce wearing and tearing in the back that pivots, after wearing and tearing, the torsion that pivot has is originally descended, the position that should locate after make that screen can not be certain be positioned to lift opened, can make screen produce the problem that to locate really, necessity of being improved is arranged in fact.

The utility model content

In view of this this creator is to set about researching and developing, and understands the problem that produces in use in the hope of solving the above-mentioned person of commonly using, and through constantly test and effort, develops the utility model finally.

Fundamental purpose of the present utility model is to provide a kind of no section pivot of adjusting torsion, to improve the above-mentioned problem that exists, this nothing section pivot mainly is to use on mobile computer or mobile phone or desktop screen, and can reach a purpose of adjusting nothing section pivot torsion, so that screen can be positioned place, user desired position really.

In order to reach above-mentioned utility model purpose, the utility model is to take following technological means to be reached, and the utility model comprises:

Not having the section pivot is that pivot, pin axial sleeve with mutual fit and the packing ring set that is placed on the pin axial sleeve outside are formed, pivot is fixedly arranged on the main body, pin axial sleeve is fixedly arranged on the screen, pivot one side is provided with right cylinder, pin axial sleeve is established plural pieces torsion trimmer with respect to the right cylinder external rings, the outside pivot place relatively of torsion trimmer is formed with the tapering, form the cutting plane with respect to packing ring set place on each torsion trimmer, the packing ring set inside that is placed on each torsion trimmer outside is formed with the taper hole that cooperatively interacts.

Innovative design provided by the utility model, the concrete effect enhancement that can obtain comprises:

Can adjust the torsion that does not have the section pivot, so that screen can be located really: but the utility model mainly mat adjust packing ring and be placed in position on the pin axial sleeve, make pin axial sleeve more tighten pivot,, make screen can be positioned place, user desired position really to adjust torsion.

Embodiment

Please referring to Fig. 1 to shown in Figure 3, the utility model is for can adjusting the no section pivot of torsion, be first embodiment of the present utility model, includes:

Pin axial sleeve 20, plurality of fixed hole 21 is set on pin axial sleeve 20, pin axial sleeve 20 is sentenced appropriate intervals distance the curved torsion trimmer 22 of several pieces sections is set, and each torsion trimmer 22 outside is formed with tapering 23, is formed with all respectively in the lateral margin of each torsion trimmer 22 and scabbles face 24;

The packing ring set 30 that is hollow cylindrical, it is to be placed on each torsion trimmer 22 outside places, in packing ring set 30 internal production taper holes 31, and forms with torsion trimmer 22 outside taperings 23 and to connect airtight as shown in Figure 5;

Pivot 10 is provided with plurality of fixed hole 11 on pivot 10, in pivot 10 1 sides one right cylinder 12 with suitable length is set, and this right cylinder 12 is to be placed between each sheet torsion trimmer 22 of pin axial sleeve 20.

As Fig. 2,3, shown in 4, the combination of mat said structure, earlier packing ring set 30 is placed on outside each torsion trimmer 22 of pin axial sleeve 20, right cylinder 12 with pivot 10 is placed between each torsion trimmer 22 again, by adjust packing ring set 30 in each torsion trimmer 22 outside to the appropriate position, to produce appropriate torsion, when using, can be fixedly arranged on main body 40 places of mobile computer by the fixed orifice 11 of pivot 10 1 sides, the fixed orifice 21 of pin axial sleeve 20 1 sides is fixedly arranged on screen 50 places of mobile computer, when screen 50 with respect to main body 40 in lift open after, screen 50 is stagnated be positioned the needed suitable angle of user place, for the user in the need of watching screen 50; Aforesaid nothing section pivot also can be applicable to mobile phone or desktop screen, and is same, can reach identical aforesaid utility model purpose.

As shown in Figure 5, no section pivot in the utility model, this nothing section pivot is to adjust its torsion, if the torsion of the section of nothing pivot is in using the back to reduce because of excessive wear, when needing to increase this torsion that does not have the section pivot, the position that the packing ring set 30 among Fig. 5 can be pushed to suitable tightness towards the right side as shown in Figure 6, also can make the taper hole 31 of packing ring set 30 inside push the tapering 23 of each sheet torsion trimmer 22 outside, can make each sheet torsion trimmer 22 become state more closely towards right cylinder 12 outside place crampings respectively.

The effect of the cutting plane 24 among Fig. 3 is: can produce tension force because of the extruding of the packing ring set 30 of outside, to remedy pivot 10, pin axial sleeve 20 in the back torsion decline problem that is caused of wearing and tearing, also can increase pivot 10, pin axial sleeve 20 in difficulty in relative rotation, increasing the friction of this nothing section pivot, so that the screen 50 among Fig. 4 can be positioned the needed position of user in lifting after opening really.

As shown in Fig. 7, Fig. 8, be second embodiment of the present utility model, major part is same as the structure in the earlier figures 2, its difference be in: increase a bronze medal or its alloy system wear ring 60, one short slot 61 and more than one fixing groove 62 are set on this wear ring 60, this wear ring 60 is placed between each torsion trimmer 22 inside and the right cylinder 12, and is positioned between each torsion trimmer 22 with fixing groove 62, can reach and improve its locating effect purpose.
