Abstract

The utility model relates to a convenient key ring which can be easily hung and taken. The convenient key ring comprises a double-layer key ring, wherein a first-layer ring body and a second-layer ring body of the double-layer key ring are respectively to be clamp-shaped, the ring wall of the second-layer ring body is thinner than that of a second-layer ring head, and the ring head of the first-layer ring body corresponds to the ring head of the second-layer ring body up and down. The convenient key ring has the advantages that firstly, the design that the double-layer ring body of the double-layer key ring is close to a plane can be changed into a shape-adding design according to the principle of curve design, and one end of the key ring can be opened in the manner of clamp-shaped press, so that the key can be conveniently hung and taken, and the key ring is convenient and quick; and secondly, the convenient key ring is simple in structure and high in practical applicability.

Description

The Key ring

Technical field

The utility model relate to a kind of can be like a cork with on the key hook and the Key ring that takes off, belong to daily living article and make the field.

Background technology

Usually on the market key ring, simply with regard to several rings, every less important opening when hanging key had to nail or looked for instrument to help, and nail is possible impaired, and instrument can not all be with at one's side at any time, is very much to allow the people have a headache.

The utility model content

Purpose of design: avoid the weak point in the above-mentioned background technology, design a kind of can be like a cork with on the key hook and the Key ring that takes off.

Design: for realizing above-mentioned purpose of design, the utility model is on structural design, the circle wall that the ring body of double-deck key ring ground floor ring and second layer ring is folder shape and second layer ring ring body is thinner than the circle wall of second layer ring ring head, the up and down corresponding design of the ring head of ground floor ring and the ring head of second layer ring is technical characteristics of the present utility model.The purpose of doing like this is: when needs are worn key, because the circle wall of second layer ring ring body is thinner than the circle wall of second layer ring ground floor ring ring head, ground floor ring and the second layer ring of pushing down double-deck key ring are the ring body that presss from both sides shape, the ring head of ground floor ring is upturned after pressed down by ground floor ring ring body, be convenient to ground floor circle body ring head and penetrate keyhole, wear key action thereby finish; When needs take out key, the action that repeats equally to wear key, with a ring perk of ground floor ring, make key along the ring head of ground floor ring enter the circle body of double-deck key-ring, finish the action of withdrawing from double-deck key-ring.

Technical scheme: a kind of Key ring, comprise double-deck key ring, the circle wall that the ring body of described double-deck key ring ground floor ring and second layer ring is folder shape and second layer ring ring body is thinner than the circle wall of second layer ring ring head, and is corresponding about the ring head of ground floor ring and the ring head of second layer ring.

The utility model is compared with background technology, the one, used the principle of Curve Design, it is that the design on a plane changes into and adds the shape design that the two-layer ring body that changes double-deck key ring is close to, and in the mode that the folder shape is pressed one end of key ring is opened, conveniently hang and take key, convenient and swift; The 2nd, simple in structure and practical.
