Description

Key ring

Technical Field

The utility model relates to a key ring.

Background

The existing key ring is mainly composed of two or more rings which are arranged in parallel along the axial direction, for example, the invention with the application number of 201310665180.0 discloses a labor-saving key ring buckle. To sleeve the key into the key ring, the end of the ring is pried by a nail, and then the key hole is penetrated into the pried end. The conventional key ring structure is not easy to pry up due to the end head, a key is difficult to penetrate, and the conditions of clamping fingers and damaging nails are often generated, so that the conventional key ring structure is inconvenient. The same problem occurs when the key is removed.

In order to solve the above problems, the invention patent ZL201080065738.6 discloses a key ring with compressible voids, comprising a wire (2) arranged in at least two rings (20, 21, 22) to provide a resilient spiral (1), said spiral (1) having a first and a second end (23, 24), wherein the first end portion (23) is forced to tightly contact the first surface (21A) of the lower circular ring (21) by means of inertial elasticity, while the second end (24) is forced to tightly contact the second surface (20B) of the upper ring (20), wherein at least one end (23) is openable, characterized in that the opening of the key ring is achieved by means of a bend (3) and a peak (3A) arranged to form a first U-shaped void (4), the peak (3A) provides a second compressible void (5) between the at least two rings (20, 21, 22) (see claim 1 hereof).

Although the technical problem that the end is difficult to pry and the key is difficult to penetrate is solved, the axial thickness of the key ring is increased due to the fact that the first U-shaped gap (4) and the second compressible gap (5) are arranged, and the key ring is not convenient to carry.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a key ring, need not to prize the end with the nail, alright embolia the key easily.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a key ring comprises an upper ring and a lower ring which are made of an elastic wire, wherein the elastic wire is bent and overlapped at the right side joint of the upper ring and the lower ring to form a horizontal section, and two end parts of the elastic wire are overlapped on the left sides of the upper ring and the lower ring by means of the elasticity of the elastic wire to form a key assembling and disassembling section.

The key loading and unloading section is arranged in parallel and level with the horizontal section, and the gap between the right end of the key loading and unloading section and the left end of the horizontal section is 0-20 mm.

The clearance between the right end of the key assembling and disassembling section and the left end of the horizontal section is 3 mm, or 5 mm, or 7 mm.

The upper ring and the lower ring are both oval, and the lower ring is arranged on the upper ring.

The length of the horizontal section is 0-20 mm.

The cross section of the elastic wire is rectangular, and the elastic wire is made of elastic stainless steel or elastic plastic.

The right end of the key assembling and disassembling section is provided with an opening.

Compared with the prior art, the beneficial effects of the utility model are that: due to the adoption of the technical scheme, a nail buckle is not needed when the key is installed, and the key is very convenient. The key ring is located and fits with a contraceptive ring, the key is located the lower ring, this kind of structure, it is more reasonable to distribute, be convenient for more the selection and the loading and unloading of key, moreover, the key ring is fitting with a contraceptive ring the key under, because the effect of gravity, the key is in flagging state, even if elasticity of elastic wire weakens, the clearance appears occasionally in key loading and unloading section, the key also can not deviate from key loading and unloading section, even if the key removes key loading and unloading section left side because vibrations, certain bulldozing force does not have, the key handle also can not deviate from key loading and unloading section.

Because the upper ring and the lower ring are oval, under the condition that the whole size is not increased (compared with the existing key ring), the width of the lower ring is not changed, and the number of keys hung on the lower ring is not reduced basically. In addition, the existing key ring is round and has a monotonous appearance, and the utility model has the appearance exactly like a gourd and an attractive appearance.

The elastic wire rod is connected at the right side joint of the upper ring and the lower ring through spot welding to form a horizontal section, and the structure is simple to manufacture and low in processing cost.
