Abstract

The utility model discloses a concavo-convex wheel oil groove point structure comprising a handle and a ringlike body, wherein the surface of the ringlike body is provided with two groups of oil groove points; and the oil groove points extend to the outer side from the inner side of the surface of the ringlike body, and are oppositely arranged and can be shaped like an oblique rectangle, an oblique spot or an oblique camber. As the oil groove points are designed to be shaped like oblique rectangle, oblique spot or oblique camber, surface oil supplementation lubrication can be conducted on a concavo-convex wheel and metal parts contacted with the concavo-convex wheel, the attrition among the metal parts is reduced and the service life of the concavo-convex wheel and the metal parts is prolonged.

Description

The concavo-convex oil groove dot structure of taking turns

Technical field

The utility model relates to a kind of rotating shaft of notebook computer, especially relates to the concavo-convex salient point position structure of taking turns on a kind of notebook computer rotation shaft, belongs to technical field of electronic products.

Background technique

In actual life, computer becomes study, necessary tool such as work or leisure, and notebook computer is light and handy because of it, characteristics such as be convenient for carrying extensively are the user's favorite, we know, computer comprises display screen and main frame two-part, notebook computer links together these two-part by a rotating shaft, form retractable structure, the support that is display screen and main frame is enclosed within respectively in the notebook rotating shaft, thereby realize the folding of notebook display screen by the rotating shaft of rotating notebook, so the notebook rotating shaft has been played important effect in the using process of notebook.

In addition, we know in the rotating shaft of notebook and also are provided with concavo-convex the wheel.

Fig. 1 is traditional concavo-convex structural representation of taking turns oil groove point, as shown in Figure 1: the concavo-convex wheel has racket shape structure, it comprises handle 2 and ring body 1, on the surface of ring body 1, form concavo-convex mechanism, so that the parts that are in contact with it well cooperate, because the notebook rotating shaft is when rotating, have relative rotation between the concavo-convex metal parts of taking turns and being in contact with it, therefore, will produce friction between the metal parts, so just need between each parts to lubricate, so concavo-convex the wheel is provided with oil groove point 3, the concavo-convex parts of taking turns and being in contact with it are carried out repairing, so that with the concavo-convex parts that contact of taking turns when relatively rotating with it, obtain well lubricatedly, reduce wear.But, we know, traditional oil groove point 3 is to realize by the oil groove point 3 that a plurality of point-like are set on the surface of ring body 1, and the oil groove of these a plurality of point-like point is arranged on the same circle, this kind mode makes in lubricated process, point radian in the middle of oil groove point 3 can only lubricate, and can not form a face radian, the area that obtains lubricating is very little, repairing is single, can not whole repairing, make contact concavo-convex take turns and metal parts between wearing and tearing very big, reduced concavo-convex working life of taking turns with metal parts.

The model utility content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of concavo-convex oil groove dot structure of taking turns that can carry out repairing to concavo-convex whole face of taking turns.

This practical being achieved through the following technical solutions:

A kind of concavo-convex oil groove dot structure of taking turns comprises handle and ring body, and the surface of ring body is provided with the oil groove point, it is characterized in that: above-mentioned oil groove point extends to the outside from the inboard of ring body surface, is two groups, is oppositely arranged.

Above-mentioned oil groove point is any shape in oblique rectangular, oblique point-like or the oblique arc.

The beneficial effects of the utility model are: the utility model is by being designed to the oil groove point any shape in oblique rectangular, oblique point-like or the oblique arc, it is lubricated to carry out the repairing of face to the concavo-convex metal parts of taking turns and being in contact with it, lubricated area is big, reduce the wearing and tearing between the metal parts, prolonged concavo-convex working life of taking turns with metal parts.

Description of drawings

Fig. 1 is traditional concavo-convex structural representation of taking turns oil groove point;

Fig. 2 is the utility model one embodiment's a structural representation one;

Fig. 3 is the utility model one embodiment's a structural representation two;

Fig. 4 is the utility model one embodiment's a structural representation three.

Main reference character implication is among the figure:

1, ring body 2, handle 3, oil groove point 3a, oblique rectangular oil groove point

3b, oblique point-like oil groove point 3c, oblique circular arc oil groove point

Embodiment

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail:

Fig. 2 is the utility model one embodiment's a structural representation one; Fig. 3 is the utility model one embodiment's a structural representation two; Fig. 4 is the utility model one embodiment's a structural representation three.

Extremely shown in Figure 4 as Fig. 2: the concavo-convex oil groove dot structure of taking turns, comprise handle 2 and ring body 1, the surface of ring body 1 is provided with oil groove point 3, and oil groove point 3 extends to the outside from the inboard on ring body 1 surface, is two groups, is oppositely arranged.Wherein, as shown in Figure 2: oil groove point 3 is oblique circular arc oil groove point 3c; As shown in Figure 3: oil groove point 3 is oblique point-like oil groove point 3b; As shown in Figure 4: oil groove point 3 is oblique rectangular oil groove point 3a.

Above-mentioned oil groove is put 3 structures, makes concavo-convex the wheel when the metal parts that is mated relatively rotates, and oil groove point 3 can carry out planar repairing, makes lubricated area increase, and high lubricating effect has prolonged concavo-convex working life of taking turns with metal parts.

Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.

Claims

1. the concavo-convex oil groove dot structure of taking turns comprises handle and ring body, and the surface of ring body is provided with the oil groove point, it is characterized in that: above-mentioned oil groove point extends to the outside from the inboard of ring body surface, is two groups, is oppositely arranged.
