Abstract

The utility model provides a key ring, comprising an annular body compising a plurality of connecting rings arranged on the circumference surface of the annular body and connected in order, and the two connecting rings at the two outermost sides are connected together through a connecting mechanism. The connecting rings have strong flexibility, because the connecting rings can be deformed in extending for the user's big hand to be sheathed when the size of the key ring is small.

Description

Key-ring

Technical field

The utility model relates to a kind of key-ring that is enclosed within on the wrist.

Background technology

In the prior art, be typically provided with safety cabinet in places such as bathroom or recreation grounds being convenient for people to stored article, and for safe ready, usually key to the safe hung on the key-ring, key-ring can be enclosed within on user's the wrist.For attractive in appearance and durable, existing key-ring surrounds annular by plastic material usually and makes, but because the plastic material scalability is less, so every kind of key-ring is only applicable to the suitable people of size, this Chang Yi causes trouble for off size suitable people.

Summary of the invention

The utility model purpose provides the stronger key-ring of a kind of extensibility.

For achieving the above object, the technical solution adopted in the utility model is: a kind of key-ring, comprise ring body, described ring body comprises a plurality of clamping rings, described a plurality of clamping ring is arranged on the circumferential surface of ring body and is connected successively, lays respectively between two clamping rings of outermost both sides to be connected by bindiny mechanism.

Because technique scheme utilization, the utility model compared with prior art has following advantage: ring body comprises a plurality of clamping rings that are connected, because clamping ring can be out of shape when stretching, so its retractility is stronger, when and hand user less when the size of key-ring is big, distortion by clamping ring is stretched, and makes the user to put like a cork.

The specific embodiment

Be typically provided with safety cabinet in places such as bathroom or recreation grounds being convenient for people to stored article, and for safe ready, usually key to the safe hung on the key-ring, key-ring can be enclosed within on user's the wrist.For attractive in appearance and durable, existing key-ring surrounds annular by plastic material usually and makes, but because the plastic material scalability is less, so every kind of key-ring is only applicable to the suitable people of size, this Chang Yi causes trouble for off size suitable people.The utility model provides a kind of retractility stronger key-ring, and the scope of application is wider, below in conjunction with accompanying drawing the utility model is specified.

Referring to accompanying drawing 1-accompanying drawing 3, a kind of key-ring, comprise ring body 1, described ring body 1 comprises a plurality of clamping rings 6, described a plurality of clamping ring 6 is arranged on the circumferential surface of ring body 1 and is connected successively, lays respectively between two clamping rings 6 of outermost both sides to be connected by bindiny mechanism.The sidepiece of described each clamping ring 6 is extended with connecting portion 7 along the circumferencial direction of ring body 1, is connected by connecting portion 7 between described adjacent two clamping rings 6.Described bindiny mechanism comprise the locking bar 2 that is connected with the clamping ring 6 of outermost one side, with the clamping block 4 that the clamping ring 6 of outermost opposite side is connected, described locking bar 2 is connected with clamping block 4.In places such as bathrooms, described ring body 1 is provided with the safety cabinet that nameplate 3 mates with the indication and the institute key of being hung, and the comfort in order to guarantee to use, and described nameplate 3 is pivotally connected on the locking bar 2.Because clamping ring 6 can be out of shape when stretching, so its retractility is stronger, when and hand user less when the size of key-ring is big, distortion by clamping ring 6 is stretched, make the user to put like a cork, and, in the process of key kit circle, the contraction of clamping ring 6 is less to the influence of human body skin, can strengthen comfort.

Referring to accompanying drawing 2, have lockhole 8 on the described clamping block 4, have the card-tight part 5 that radially becomes big on the described locking bar 2, described locking bar 2 passes lockhole 8, and described card-tight part 5 is stuck in the oral area of lockhole 8.On the described card-tight part 5 the side near the outer end of locking bar 2 have that radius reduces gradually domatic 9.Key cover penetrates locking bar 2 in the lockhole 8 after on the locking bar 2, domatic 9 be subjected to lockhole 8 hole wall pressure and after passing lockhole 8, card-tight part 5 firmly is stuck in the oral area of lockhole 8, make locking bar 2 be connected safely with clamping block 4.
