CN202750852U - Size-adjustable ring circle - Google Patents

Abstract

The utility model provides a size-adjustable ring circle comprising an inner circle and an outer circle. The surface of the inner circle is designed into a smooth convex arc shape, a tangent plane, along the B-B' direction, of the inner circle is shaped in an ellipse, a long axis and a short axis of the ellipse correspond to the longest ring size and the shortest ring size, and the B-B' direction is a tangent plane direction of a convex arc shaped top point, perpendicular to the A-A' direction, of the inner circle. The size of the ring can be adjusted by rotating the ring circle according to the shape and size of a finger, no special size customization or modification is required, so that environmental pollution caused by electroplating during size modification is avoided.

Description

The ring that adjustable hand is very little

Technical field

The utility model relates to a kind of ring, is specifically related to the very little ring of a kind of adjustable hand.

Background technology

Ring is as modal jewellery type, and diamond ring is because the rigid demand occuping market trading volume of wedding celebration market leading.Existing ring inner ring mostly is circular smooth inwall, and long periods of wear is guarded against wall and can be pushed by adversary's fingering row, forms impression; Especially in the season of high temperature, people's finger can raise and the appropriateness expansion along with temperature, and the extruding meeting more obviously causes discomfort.

At present, the ring that domestic Jewelry Market is sold all can change for the thickness of client's finger hand cun service, and the very little modification of hand not only destroys the degree of perfection of bullion details, and hand cun amended again a plating especially can be to environment.

On the market, the comfort of wearing for pursuing ring improves ring inside, alleviate the ring space to the pressure of finger with smooth convex arc shaped inwall, but it is very little to change hand, can only accept customization, and affect circulation of commodities.

For the CN2430048Y name is called the utility model patent of " ring ", disclose a kind of ring such as Granted publication number, its inner ring and surface, outer ring are circular shape; The sectional area oval in shape of the top of ring, middle part and bottom.As describing in its specification, the inner peripheral surface of circular shape is to make the contact-making surface of ring and finger little, and then the phenomenon of dermatitis can not occur, and frictional force is little simultaneously, so that wear and take off all than being easier to.

In the contrast patent, the diminishing circular shape of inner peripheral surface is so that comfortable wearing, the elliptical shape of mentioning in the contrast patent is different from the elliptical shape that the utility model is mentioned, as the accompanying drawing 2-4 that contrasts patent as can be known, its elliptical shape is the shape of the sectional area of part, elliptical shape of the present utility model is along the sectional drawing on the B-B ' direction (as shown in Figure 4), the elliptical shape of the utility model ring inner ring, principle is hand corresponding to the different-diameter that exists in the ellipse cun, can reach the very little purpose of Self-adjustment hand by rotary ring, thereby it is very little to need not additionally to adjust hand.

The utility model patent that is called " a kind of ring " such as Granted publication number for the CN201267238Y name, disclose a kind of ring inner surface and be the ring of the arc of projection, the cross section at its top is the elliptical shape of nearly circle, the cross section oval in shape of both sides, and the bottom section is flat elliptical shape.The purpose of this structure also is so that the ring comfortable wearing, and the contact-making surface of ring and finger is little, is difficult for injured skin etc.Elliptical shape in this contrast patent also is local elliptical shape, and is different from the elliptical shape in the utility model, and the technique effect that produces is also fully different.

The utility model content

The purpose of this utility model is to provide a kind of comfortable wearing, can regulates voluntarily the very little ring of hand, and there is not environmental pollution in an adjusting hand cun process.

The ring that a kind of adjustable hand that the utility model provides is very little, comprise inner ring and outer ring, the surface design of described inner ring becomes smooth convex arc shaped, and described inner ring is along the tangent plane oval in shape on the B-B ' direction, the corresponding the longest hand with minor axis of the major axis of described ellipse cun and short hand cun; Described B-B ' direction be along with the tangent plane direction of the inner ring peak of the tangent line A-A ' perpendicular direction of inner ring.

As a kind of preferred version of the present utility model, the ratio of described minor axis and major axis is 1:1.01 to 1:1.2.

As a kind of preferred version of the present utility model, the ratio of described minor axis and major axis is 1:1.04.

As a kind of preferred version of the present utility model, described major axis is 17.2mm, and described minor axis is 16.5mm.

As a kind of preferred version of the present utility model, the peak of described inner ring and the distance of minimum point are C, and the distance of described inner ring minimum point and outer ring is D, and the ratio of described C and D is 1:2 ~ 1:10.

As a kind of preferred version of the present utility model, the ratio of described C and D is 1:3, and this preferred ratio will be so that ring be worn more comfortable.

The utility model is the ellipse of nearly circle with the revolutionary improvement of the standard circular of ring inner ring, and anatomy shows the oval shape that more meets finger.

The surface design of ring inner ring becomes smooth convex arc shaped, reduces the contact-making surface of ring and finger, can lower ring to the pressure of finger.

Simultaneously, the utility model utilizes oval-shaped two diameter feature different in size, it is very little to set the longest and the shortest two different hands at the ring inner ring, certainly the intermediate point of these two the longest and short hand cun distances then is size hand placed in the middle cun, diameter according to different parts on the elliptical shape is all different, namely between minor axis and major axis, client can carry out hand cun adjustment according to finger shape and thickness rotation ring, and it is very little to need not hand customized especially or the modification ring, thereby has avoided revising cun environmental pollution that middle plating causes of ring hand.The thinner consumer of finger can wear and take off by the rotation ring for the finger joint is large, thereby has solved the bad difficult problem of wearing into bad taking-up of ring of suitable dimension.

The utility model be applicable to not have the circle of independent rabbet guard against with to guarding against.

Description of drawings

Fig. 1-2 is the structural representation of the very little ring of the utility model adjustable hand.

Fig. 3-4 is that the very little ring of the utility model adjustable hand is along the profile of A-A ' tangential direction.

Fig. 5 is that the utility model is along the sectional drawing of B-B ' direction.

The specific embodiment

Below in conjunction with accompanying drawing concrete structure of the present utility model is described.

Please in conjunction with Fig. 1-5, the ring that the utility model adjustable hand is very little comprises inner ring 2 and outer ring 1, and outer ring 1 is circular, and inner ring 2 is the ellipse of nearly circle.The oval corresponding the longest hand with short shaft diameter a of major axis b cun and short hand cun, the ratio of minor axis and major axis is 1:1.04, and major axis is 17.2mm, and minor axis is 16.5mm, i.e. very little all can wear by Self-adjustment between 16.5 ~ 17.2mm of hand.As shown in Figure 3-4, the surface design of inner ring 2 becomes smooth convex arc shaped, and the peak of inner ring and the distance of minimum point are C, and the distance of inner ring minimum point and outer ring is D, and the ratio of C and D is 1:3, reduces the contact-making surface of ring and finger, lowers ring to the pressure of finger.
