Abstract

The utility model discloses a key ring which comprises a key retaining ring. Each end of the key ring body is provided with a small hole at a position that corresponds to the key retaining ring. A top end of a closed stop hook is closely jointed with the key retaining ring and forms a ring-shaped member, and the other end is provided with two heads which are composed of two metal wires and are bent inwards so the two end heads are inserted into the small holes and can be rotated. The two metal wires are elastic wires which have a certain strength and can cause elastic force reversion and are at an angle with each other. In using, the key ring can be detached just through squeezing the closed shift hook inwards and creating a gap on the closed ring. After an outside force is cancelled, the closed shift hook can closely cling to the key retaining ring by means of the elastic force which is caused by the closed shift hook. The key ring has the following advantages: simple structure, saved manufacturing process, no relationship between the elastic force and the structure of key ring body as only the elastic force of the metal wire is utilized and the elastic force is limited by the material of the metal wire, reduced design difficulty and reduced manufacturing cost.

Description

A kind of key chain

Technical field

The utility model relates to a kind of key chain that is used for Coordinates key.

Background technology

Present key chain, except the function that satisfies general suspension key, the effect that also needs to show individual character He reach beautiful decoration, and be convenient for carrying.Existing key chain, the general elastic device that adopts is close to stop hook hook and is linked to be a complete closed circular, to guarantee that key chain just can hang on the waistband and do not come off, its elastic device is generally stage clip or torque spring, but its weak point is, complex structure, thereby damage easily, and be difficult to seek supporting with it part, thereby renewal part is cumbersome.As Chinese patent 200920062287.5 disclosed key chains, sealing stop hook one end is a hook formation, and be sleeved on the cross bar in the key ring body, the other end is abutted against mutually with the key ring ring and constitutes ring-type, the hold down gag of spring and so on is loaded in the space that sealing stop hook and key ring body side surface hold, the unlatching of control sealing stop hook is with closed, its advantage is, the removable stop hook of sealing down comes renewal part, and need not to pay many work, other has the patent of CN201097707Y, adopts torque spring to seal the sealing ring that is formed by arc hook and sealing stop hook automatically, when inside extruding, key chain can be taken off from waistband, when external force was cancelled, torque spring was bestowed a reaction force, and the sealing stop hook just resets and becomes complete closed circular with the button figure.The shortcoming of above-mentioned patented product is, but its weak point is that needs are made the key ring body that can hold elastic pressuring clamping device, increased manufacturing cost, in addition, need the accurately position of each assembly of control, otherwise will cause the excessive or too small shortcoming of elastic force and cause inconvenience in the use.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of key chain, and it is simple in structure, appearance fashion and easy to use.

Key chain described in the utility model, comprise the key ring body, there are first aperture and second aperture in key ring body one end and the corresponding position of key ring ring and lay respectively at the both sides, front and back of key ring body, the top of sealing stop hook is abutted against mutually with the key ring ring and is constituted ring-type, the other end is first of forming of two one metal wires and second and bends inwards, making wins terminal and second terminal inserts in first aperture and second aperture rotatable respectively, described two one metal wires are to have certain intensity, but the elastic yarn of back stretch, and form certain angle.

In addition, the first terminal head and second not the position of termination not on same horizontal plane; The sealing stop hook also can be for being surrounded nonocclusive U type structure by wire, the top of its U type structure is abutted against mutually with the key ring ring and is constituted ring-type, and first and second of the other end bends inwards and make the termination and second of winning not not insert first aperture and second aperture respectively in the termination; Described wire is a steel wire; But ring-type and suit key ring circle that the described key ring body other end can have another sealing stop hook and key ring ring to surround.

Key chain described in the utility model, its key ring body is a solid construction, and will seal stop hook or U type wire one termination key ring ring, the aperture on another termination key ring body.Like this, the elastic force sealing key ring ring that can rely on wire to produce, and will sealing stop hook, the elastic force that need not stage clip or torque spring abuts against on the key ring ring, such benefit is simple in structure and has saved fabrication schedule, in addition owing to just rely on elastic force wiry, thereby the degree of tightness of elastic force limits by the material of itself only, and and the structure-irrelevant of key ring body, thereby reduce design difficulty and reduce production costs.

The specific embodiment

As Fig. 1, shown in Figure 3, a kind of key chain, comprise key ring body 1, there are first aperture 3 and second aperture 4 in key ring body 1 one ends and key ring ring 9 corresponding positions, the top of sealing stop hook 2 is abutted against mutually with key ring ring 9 and is constituted ring-type, the other end is first 5 and second 6 of two one metal wires composition and bends inwards, making wins inserts in first aperture 3 and second aperture 4 rotatable for terminal 7 and second terminal 8, the position of two terminal heads is not on same horizontal plane, described two one metal wires are to have certain intensity, but the elastic yarn of back stretch, and form certain angle 10.

As Fig. 2, shown in Figure 4, described sealing stop hook 2 also can be for being surrounded nonocclusive U type structure by wire, the top 11 of its U type structure is abutted against mutually with key ring ring 9 and is constituted ring-type, first 5 and second 6 of the other end bend inwards make two not termination first insert in first apertures 3 and second aperture 4 termination 8 termination 7 and second; In addition, but ring-type and suit key ring circle 14 that key ring body 1 other end has another sealing stop hook 12 and key ring ring 13 to surround.

Two one metal wires are owing to make certain angle, and two aperture first apertures 3 and second aperture 4 are positioned on the same vertical line, thereby during operation, because elastic force wiry, sealing stop hook 2 and key ring bad 9 are abutted against mutually and compress.

Key chain described in the utility model, its key ring body is a solid construction, and with U type elastic yarn one termination key ring ring, the aperture on another termination key ring body.Like this, the elastic force sealing key ring ring that can rely on elastic yarn to produce, and will sealing stop hook, the elastic force that need not stage clip or torque spring abuts against on the key ring ring, such benefit is simple in structure and has saved fabrication schedule, in addition owing to just rely on the elastic force of elastic yarn, thereby the degree of tightness of elastic force limits by the material of itself only, and and the structure-irrelevant of key ring body, thereby reduce design difficulty and reduce production costs; After taking off key chain, cancel pressing force, the sealing stop hook just restores to the original state under the effect of elastic force.
