Abstract

A double-shaft hinge device consists of a first pivot, a second pivot and a sleeve barrel. The first pivot and the second pivot are both provided with a jointing part and an extending part, and the jointing part and the extending part form a whole. The extending parts of the first pivot and the second pivot are respectively provided with a first oil slot and a second oil slot. The sleeve barrel is a hollow column body. The extending parts of the first pivot and the second pivot are respectively laid inside the column body. One side of the outer surface of the column body is provided with a channel along the axial direction, a gap which is communicated with the channel is arranged in the radial direction. The inside of the column body is provided with a plurality of inner oil slots. The interaction of the oil slots of the utility model can provide the proper lubricating function, which can prolong the service life of the whole hinge device.

Description

The twin axle pivot

Technical field

The utility model relates to a kind of connection set, relates in particular to a kind of twin axle pivot that increases the service life.

Background technique

General pivot as shown in Figure 6, has a pivot 50 and a belled part 60.This pivot 50 has one first plat part 51 and one 52.This axle 52 is to form one with this first plat part 51.This belled part 60 is to have a hollow and corresponding to this 52 cylindrical body 61 and one second plat part 62.

When the assembling of above-mentioned pivot, this 52 is cylindrical body 61 inside that are set in hollow, and then, this 51,61 of first and second plat part is arranged on the different objects respectively, for example the main frame of laptop computer and screen.

When observing above-mentioned existing pivot action, find to the source that screen produces enough frictional force be this 52 and hollow circular cylinder 61 inner surfaces between friction.So, the pivot of this class in use for some time, since all frictional force all come from this 52 and hollow circular cylinder 61 internal surfaces between friction, no matter so be this axle 52 or be that this hollow circular cylinder 61 all can wear away fast, so that cause shorten the working life of whole pivot.

Therefore the poor practicability of above-mentioned existing pivot, and in addition improved necessity is arranged.

Summary of the invention

In order to overcome the weak point in working life that existing pivot exists, the shortcoming of poor practicability, the utility model provides a kind of twin axle pivot, and the interaction between each oil groove that it was provided with can provide adequate lubrication, so can prolong the use life time of pivot integral body.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of twin axle pivot, it is characterized in that, it is by one first pivot, one second pivot and a sleeve are formed, this first and second pivot all has a joining portion and an extension part, this joining portion is to form one with extension part, the extension part of first and second pivot is provided with first oil groove and second oil groove respectively, this sleeve is a hollow circular cylinder, the extension part of aforementioned first and second pivot is placed in this cylindrical inside respectively, one side of its outer surface offers a ditch vertically, then offer one and the seam that is connected of this ditch diametrically, this cylindrical inside is to have several inner oil sumps.

The beneficial effects of the utility model are that the interaction between each oil groove that it was provided with can provide adequate lubrication, so can prolong the use life time of pivot integral body.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Plan view from above when Fig. 2 is the expansion of the utility model sleeve;

Phantom when Fig. 3 is the utility model combination;

Fig. 4 is a user mode schematic representation of the present utility model;

Fig. 5 is another embodiment's of the utility model sleeve a schematic perspective view;

Fig. 6 is the perspective exploded view of existing pivot.

Number in the figure illustrates 110 open-works, 12 extension parts, 121 oil grooves, 20 second pivots, 21 joining portion, 10 first pivots, 11 joining portion, 210 open-works, 22 extension parts, 221 oil grooves, 30 sleeves, 31 ditches, 32 seams, 33 inner oil sumps, 40 laptop computers, 41 screens, 42 main frames

Embodiment

See also Fig. 1, wherein, twin axle pivot of the present utility model is made up of one first pivot 10, one second pivot 20 and a sleeve 30.

This first and second pivot 10,20 all has a joining portion 11,21 and an extension part 12,22.This joining portion the 11, the 21st and extension part 12,22 form one, and all are provided with several through holes 110,210 at each 11,21 place, joining portion, and by this through hole 110,210, this first and second pivot 10,20 is installed on the different planes discriminably; For example on the screen and main frame of laptop computer.Each extension part 12,22 then is respectively equipped with first oil groove and second oil groove 121,221.

This sleeve 30 is a hollow circular cylinder, and the one side offers a ditch 31 vertically, then offers one and the seam 32 that is connected of this ditch 31 diametrically.Consult Fig. 2, have several inner oil sumps 33 in this cylindrical inside.

Twin axle pivot of the present utility model is in when combination, see also shown in Figure 3, the extension part the 12, the 22nd of this first and second pivot 10,20, the directly inside of being inserted in this sleeve 30 by 30 two different end points of this sleeve.Because this sleeve 30 is that it axially is provided with ditch 31, so each extension part 12,22 all is contained in the inside of sleeve 30 being inserted in behind this sleeve 30 inside in friction tight mode.After each extension part 12,22 was contained in the cylindrical body inside of this hollow, the inner oil sump 33 of 121,221 in the oil groove of each extension part 12,22 and this sleeve 30 was interlaced, so, then can provide best lubrication effect when action.

By the user mode reference drawing of Fig. 4 as can be known, the utility model can utilize the screen 41 of each joining portion 11,21 laptop computer and main frame 42 affixed, so, when screen 41 pivots with respect to main frame 42, and keep screen 41 and all can divide on two extension parts 12,22 in the frictional force of opening state, and be not concentrated on the pivot, and cause excessive abrasion because of frictional force easily.

By said structure as can be known, twin axle pivot of the present utility model is to have two extension parts 12,22, so being split on two extension parts 12,22 that needed frictional force can be average when pivoting is provided, can reduce the abrasion that extension part 12,22 is brought because of friction, so can prolong the working life of whole pivot.

See also another specific embodiment of sleeve shown in Figure 5, wherein, the seam 32 ' that as seen reaches this sleeve 30 does not run through whole outer surface.So structure also can be reached needed function and purpose on the implementation.
