CN203168184U - Labor-saving key ring - Google Patents

Abstract

The utility model discloses a labor-saving key ring which comprises a three-layer metal ring overlapping structure. The labor-saving key ring is characterized in that lead angles of 20 degrees are formed between a middle metal ring of a second layer in the overlapping structure and an adjacent middle metal ring of a first layer and between the middle metal ring of the second layer and an adjacent middle metal ring of a third layer in opposite directions respectively.

Description

Laborsaving key ring

Technical field

The utility model relates to a kind of key ring of hanging key.

Background technology

The effect of key ring is key to be concentrated be enclosed within one or more key rings, not only makes things convenient for management but also be easy to carry.Present key ring commonly used, generally rolled by a strip metal wire rod and form, form superimposed twin nuclei, be adjacent between the termination of key ring and the adjacent key ring ring body, in the time of key will being packed into like this in the key ring or take out in the key ring, just need break the termination of key ring earlier into two with one's hands and again key cover be entered, owing to lean on very tightly between the termination of key ring and the ring body, and the elastic force when breaking into two with one's hands is bigger, so relatively harder.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model aims to provide a kind of key ring that can simply effortlessly key be packed into or take out.

The utility model is implemented by the following technical programs:

Laborsaving key ring comprises three-layer metal ring iterative structure, it is characterized in that: the second layer intermetallic metal ring in the described iterative structure respectively and between the adjacent ground floor intermetallic metal ring, the 3rd layer of intermetallic metal ring ring body rightabout form 20 degree lead angles.

Because the second layer intermetallic metal ring direction with key ring when making key ring is designed to certain angle; used lever principle dexterously; only need light three-layer metal ring one end of pressing just can make it open latch closure; so; need not break or break into two with one's hands a little the termination of key ring into two with one's hands and just can enter key cover without lifting an eyebrow, not only laborsaving but also protect and point.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

With reference to accompanying drawing 1, this kind key ring, comprise three-layer metal ring iterative structure, it is characterized in that: the second layer intermetallic metal ring 2 in the described iterative structure respectively and between the adjacent ground floor intermetallic metal ring 1, the 3rd layer of intermetallic metal ring 3 ring body rightabout form 20 degree lead angles 4.

Key to be packed in the key ring or with key and in key ring, take out, only need light three-layer metal ring 3 one ends of pressing just can make it open latch closure, keyhole is inserted in introducing port 5, then with key on the ring body of key ring around on two the circle after, key just can come out from another termination of key ring, packs in the key ring or takes out in key ring.

Claims (1)

1. laborsaving key ring comprises three-layer metal ring iterative structure, it is characterized in that: the second layer intermetallic metal ring in the described iterative structure respectively and between the adjacent ground floor intermetallic metal ring, the 3rd layer of intermetallic metal ring ring body rightabout form 20 degree lead angles.
