The utility model discloses key ring realizes the double insurance through ring sum key ring outer loop in setting up key ring, avoids the key to lose, sets up the anti -drop opening at the key ring inner ring, can prevent effectively that the key from coming off from the key ring inner ring to key ring's security and reliability have been increased.

Description

A kind of key chain

Technical field

The utility model relates to key chain technical field, refers to especially a kind of key chain.

Background technology

Key chain, claims again keyring lock, key-ring, key chain, key hook etc. The material of making key chain is generally metal, leather, plastics, wood etc. The articles for daily use that this thing exquisiteness is small and exquisite, the ever-changing people of being of moulding carry every day. Key chain is a kind of decorative article hanging in key-ring. The key chain of selecting collocation oneself to like to key, not only can embody individual mood and individual character, more can represent the grade of oneself simultaneously also to oneself bringing happy mood. Key chain moulding is various, and such as casper, brand moulding, simulation model etc., material is general as copper, aluminum, rubber system, plastics etc., is mainly the antirust elements such as zinc alloy surface nickel plating or rhodium now. Key chain has become a kind of present novelties at present. It is simple in structure for existing key chain, only have a simple circle body to hang key, but this structure easily causes key to cause key loss from all skidding off.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of key chain, can avoid key loss.

For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of key chain, described key chain comprises ring and key chain outer shroud in key chain, in described key chain, ring is arranged in described key chain outer shroud, in described key chain, ring is fixedly connected with key chain outer shroud, described key chain outer shroud top and bottom are circular arc, the radius of the circular arc of described key chain outer shroud bottom is greater than the radius of the circular arc at described key chain outer shroud top, described key chain outer shroud ring body is provided with outer ring interface, described outer ring interface was formed by overlapping being close to of two ends that forms key chain outer shroud ring body, in described key chain, ring bottom is circular arc, in described key chain, ring top is provided with slip-off preventing opening.

Preferably, the ring head at the two ends of described key chain outer shroud ring body is nose.

Preferably, described outer ring interface is arranged between the circular arc and the circular arc at key chain outer shroud top of key chain outer shroud bottom.

Preferably, described slip-off preventing opening is made up of the two ends of ring body in key chain, in key chain, one end of ring ring body is in vertical direction higher than the other end of ring body in key chain, and in described key chain, one end of ring ring body covers the other end of ring ring body in key chain in the horizontal direction.

Preferably, in described key chain, the two ends of ring ring body are bowed downward to arcuation.

Preferably, the circular arc of described key chain outer shroud bottom is fixed and is connected with the circular arc of ring bottom in key chain.

Preferably, the circular arc of described key chain outer shroud bottom is fixedly connected with by the mode of tying up or welding with the circular arc of ring bottom in key chain.

The beneficial effect of technique scheme of the present utility model is as follows:

In such scheme, realize double insurance by ring and key chain outer shroud are set in key chain, avoid key loss, in key chain, encircle slip-off preventing opening is set, can effectively prevent that key from coming off from encircling in key chain, thereby increase the safety and reliability of key chain.

Detailed description of the invention

For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

As shown in Figure 1, a kind of key chain that embodiment of the present utility model provides, described key chain comprises ring 1 and key chain outer shroud 2 in key chain, in described key chain, ring 1 is arranged in described key chain outer shroud 2, in described key chain, ring 1 is fixedly connected with key chain outer shroud 2, described key chain outer shroud 2 tops and bottom are circular arc, the radius of the circular arc 3 of described key chain outer shroud 2 bottoms is greater than the radius of the circular arc 4 at described key chain outer shroud 2 tops, described key chain outer shroud 2 ring bodies are provided with outer ring interface 5, described outer ring interface 5 was formed by overlapping being close to of two ends that forms key chain outer shroud 2 ring bodies, in described key chain, ring 1 bottom is circular arc 6, in described key chain, ring 1 top is provided with slip-off preventing opening 7.

Preferably, the ring head at the two ends of described key chain outer shroud 2 ring bodies is nose 8.

In the present embodiment, taking the lead can key be put into and be taken out by setting guides, thereby improves the convenience that key is put into and taken out.

In the present embodiment, can in the time that key will skid off, effectively stop key by slip-off preventing opening is set, avoid key to skid off, thereby improve security.

Preferably, the circular arc 3 of described key chain outer shroud bottom is fixed and is connected with the circular arc 6 of ring bottom in key chain.

Preferably, the circular arc 3 of described key chain outer shroud bottom is fixedly connected with by the mode of tying up or welding with the circular arc 6 of ring bottom in key chain.

In use, can, by opening outer ring interface, make key ring slide into key chain inside, and in overlapping, the slip-off preventing opening of ring arrive key chain bottom, had been and had hung into step. When extraction, make key ring walk around slip-off preventing opening and arrive outer shroud interface, pull key and complete extraction.

The key chain of the utility model embodiment, realize double insurance by ring and key chain outer shroud are set in key chain, avoid key loss, in key chain, encircle slip-off preventing opening is set, can effectively prevent that key from coming off from encircling in key chain, thereby increase the safety and reliability of key chain.

The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
