CN2883768Y - Hinger having positioning gear - Google Patents

Abstract

The utility model discloses a junction equipment with a positioning mechanism; wherein, a long groove is arranged at an rotating shaft which is in a flexible sleeve of a hinge penetrating into a base and a sunken groove is formed on the sleeve; through the cooperation of the long groove and the sunken groove, the hinge rotating makes the shaft moving, at the time when the long groove is stuck by the sunken groove, the positioning effect is achieved. The utility model has the advantage of preventing the shaft getting out of the sleeve.

Description

The pivot of tool positioning means

Technical field

The utility model refers to a kind of pivot with tool positioning means of preventing deviating from especially about a kind of pivot mechanism improvement design.

Background technique

Pivot is used in the folding device, for example has translating machine, the mini foldable keyboard of screen and button or has in the mobile phone of CCD phtographic lens, and they utilize a pivot to reach function folding or turnover.

Employed pivot in this kind folding apparatus, some can have positioning function in order to reach when launching, and can be provided with positioning means in pivot.General simple pivot has a rotating shaft and a base, and the axial region of rotating shaft passes the resilient sleeve of base, the elasticity of utilizing sleeve to provide, make axle relatively sleeve rotate and in arbitrary fixed angle.The positioning means polyphyly of this kind pivot, and has on the wall of resilient sleeve of breach also relatively along axial formation one plane along axial formation one plane the surperficial shape of axle; When the rotation of the relative base of rotating shaft, the plane that makes axle promptly constitutes certain potential energy to the sleeve part plane time.

The known positioning means of this kind because axle and sleeve part all form a plane, deviates from axle very easily from sleeve, remain improvement.

Novel content

The utility model purpose is, a kind of pivot of tool positioning means is provided, and it has locating effect, and can prevent that axle from deviating from sleeve.

The utility model structure: a kind of pivot of tool positioning means, this pivot includes rotating shaft, and described rotating shaft has a junction and one; Described pivot also comprises a base, and this base has a resilient sleeve, and this resilient sleeve has a breach; It is characterized in that:

Described axle surface has an elongated slot, and above-mentioned resilient sleeve has a hollow slot inside and that can engage the location with this elongated slot along its wall; The axle of rotating shaft rotatably is through in the resilient sleeve of base.

The utility model beneficial effect:

By said structure, the utility model has overcome the above-mentioned defective of conventional construction, has locating effect, and has prevented that effectively axle from deviating from sleeve.

Below, will structure of the present utility model and operating function be described in detail according to the embodiment shown in the drawing.

Embodiment

See also Fig. 1 to Fig. 3, pivot of the present utility model is made of a rotating shaft 10 and a base 20.

Rotating shaft 10 has the coupling shaft 11 that is connected with the folded part of folding device, and then is provided with one 12 at relative coupling shaft 11 the other ends.And base 20 is fixed on the body of folding device, and has a resilient sleeve 21.The axle 12 of rotating shaft 10 penetrates and establishes in the resilient sleeve 21, and can make rotating shaft 10 and base 20 relative rotations.

The utility model provides the pivot of tool positioning means, has mainly offered an elongated slot 13 on the axle 12 of base 20 resilient sleeves 21 is stretched in rotating shaft 10, and form a hollow slot 22 on sleeve 21; The hollow slot 22 of sleeve 21 is inwardly outstanding, when rotating shaft 10 relative base 20 rotations, axle 12 is moved in sleeve 21, and elongated slot 13 is snapped in by sleeve 21 hollow slots 22 on axle 12, thereby forms a location effect, can be referring to shown in Figure 4.

The utility model mainly will decide mechanism's structure be modified to axle on 12 elongated slot 13 and the hollow slot 22 on the sleeve 21 closely cooperate, can reach and prevent axle 12 advantages of deviating from sleeve 21, to improve the caducous shortcoming in known technology plane.

When rotating shaft 10 during in relative base 20 rotations, referring to Fig. 4,, make that axle 12 is rotatable, and because the torsion that is provided is provided sleeve 21 because resilient sleeve 21 has breach 23 and can adjust bore, make rotating shaft 10 base 20 sleeves, 22 rotations and fixing relatively.But when elongated slot 13 is buckled into by hollow slot 22, can produce a location effect.

To sum up institute is old, and the pivot of tool positioning means provided by the utility model can improve the known technology shortcoming, reaches a kind of pivot of deviating from prevented, meets the patent key element, then files an application in accordance with the law.

Claims (1)

1. the pivot of a tool positioning means, this pivot includes rotating shaft, and described rotating shaft has a junction and one; Described pivot also comprises a base, and this base has a resilient sleeve, and this resilient sleeve has a breach; It is characterized in that:

Described axle surface has an elongated slot, and above-mentioned resilient sleeve has a hollow slot inside and that can engage the location with this elongated slot along its wall; The axle of rotating shaft rotatably is through in the resilient sleeve of base.
