Description
Technical field
The present invention relates to the application methods of a kind of key ring and the key ring.
Background technique
Current key ring is mainly to be made of the annulus more than axial two circles or two circles arranged side by side, such as application No. is
201310665180.0 patent application " a kind of Labor-saving key ring fastener ".It is inserted in key ring to a key, need to be prized with nail
The end for playing annulus, then again pierces into keyhole into the end pried open.This traditional key ring structure, often because of institute
State that end is bad to be levered up, key is difficult to penetrate, while the case where pinching finger, damage nail also frequently occurs, very inconvenient.
Also there is same problem when taking out key.
To solve the above-mentioned problems, patent of invention ZL201080065738.6, which discloses one kind, " has compressible gap
Key ring ", including be configured at least two annulus (20,21,22) with provide elasticity spiral (1) wire rod (2), it is described
Spiral (1) has first end and the second end (23,24), and wherein first end (23) is forced to tightly by means of inertia elasticity
The first surface (21A) of lower side ring (21) is tightly contacted, and the second end (24) is forced to tightly contact side ring
(20) second surface (20B), wherein at least one end (23) are openable, which is characterized in that the opening of key ring be by
Arrangement formed the first U-shaped gap (4) bending section (3) and peak potion (3A) and realization, the peak potion (3A) is described at least two
The second compressible gap (5) is provided between a annulus (20,21,22) (referring to its claim 1.)
Though the program solves the technical issues of " end is bad to be levered up, and key is difficult to penetrate ", since it is provided with the first U
Shape gap (4) and the second compressible gap (5) are unfavorable for carrying so that the axial width of key ring increases.
Summary of the invention
The object of the present invention is to provide a kind of key ring and its application methods can be light without levering up end with nail
Key is inserted on ground.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of key ring, including the upper ring and a lower ring made of an elastic wire, the elastic wire is in upper ring and a lower ring
Right side junction laminates composition horizontal segment through bending, and two ends of elastic wire are laminated by means of the elastic force of elastic wire in upper
The left side of ring and lower ring constitutes key and loads and unloads section.
Section is concordant with horizontal segment is arranged for key handling, and the gap that key loads and unloads between section right end and horizontal segment left end is
0~20 millimeter.
It is 3 millimeters or 5 millimeters or 7 millimeters that key, which loads and unloads the gap between section right end and horizontal segment left end,.
The upper ring and a lower ring is ellipse, and lower ring Yu Shanghuan.
The length of the horizontal segment is 0~20 millimeter.
The cross section of the elastic wire is rectangle, and the elastic wire is with elastic stainless steel or flexible
Plastics.
The right end of the key handling section is equipped with opening.
The application method of the key ring, step 1: a hand-held key bar or the shank of the key, another hold key
Ring promotes to the right the shank of the key from the outside of key handling section；Step 2: when the front of the shank of the key reaches the right side of key handling section
When end, key bar or the shank of the key are rotated clockwise, makes the right-end openings of key handling section；Step 3: continuation promotes to the right key
Handle is located at the delthyrium of the shank of the key at elastic wire lower end, delthyrium is inserted in elastic wire lower end, is moved to the left key
Handle, so that key is threaded into lower ring.
The application method of the key ring, step 4: a hand-held key chain, another hold key ring, by key
The connector of button is promoted from the outside of key handling section；Step 5: when the front of connector reaches the right end of key handling section,
Rotary connecting joint counterclockwise makes the right-end openings of key handling section；Step 6: continue to promote connector, make the hole location of connector
At elastic wire upper end, hole is penetrated into elastic wire upper end, is moved to the left connector, so that connector is threaded into
Ring.
A kind of key ring, including upper ring and a lower ring made of elastic wire, the elastic wire is on the right side of upper ring and a lower ring
Side junction connects and composes horizontal segment by spot welding, two ends of elastic wire by means of upper ring and a lower ring elastic wire
Elastic force is laminated in the left side of the upper ring and a lower ring, is constituted key and is loaded and unloaded section.
Compared with prior art the beneficial effects of the present invention are: due to the adoption of the above technical scheme, being not necessarily to when installing key
Nail button, it is very convenient.Key chain is located at upper ring, and key is located at lower ring, and this structure, it is more reasonable to be distributed, and easily facilitates key
Spoon select and load and unload, moreover, key chain in upper ring key in lower ring, due to the effect of gravity, key is in sagging state,
Even if the elastic force of elastic wire weakens, accidentally there is gap in key handling section, and key will not load and unload section abjection from key, even if
Since vibration is moved on the left of key handling section, not certain pushing force, the shank of the key is also impossible to load and unload section from key key
Abjection.
Since upper and lower ring is ellipse, in the not increased situation of overall dimensions (compared with existing key ring), due to
Lower ring width is constant, and the key quantity of impaling will not be reduced substantially.In addition, existing key ring is all round, appearance dullness, this
Invention exactly likes cucurbit, handsome in appearance.
The elastic wire connects and composes horizontal segment by spot welding in the right side junction of upper ring and a lower ring, this structure,
Production is simple, and processing cost is low.
