Abstract

The utility model provides a kind of novel key ring, including vortex-like ring, the vortex-like outside packing material of ring outer side edges makes its outside edge profile be circle, the vortex-like ring inner ring end sets annulus to center of circle direction, and the vortex-like ring is respectively provided with the sawtooth of matches mutually at its end and the position fitted with end.The beneficial effects of the utility model are：When key is assembled and disassembled, annulus can be pulled, open vortex-like ring inner end, key is assembled and disassembled；When key loads key ring, because the presence of sawtooth, key is not easily disconnected from key ring, be difficult to lose key, the utility model modern design, simple structure can be promoted the use of.

Description

Novel key ring

Technical field

The utility model is related to a kind of key ring, and in particular to a kind of novel key ring easy to use.

Background technology

Traditional keys ring inconvenient and sweat when being put into and taking out key, and easily cause the damage to key ring It is bad.If setting unlimited buffering area at opening, easily hook to clothing, and key easily snaps in open end and causes to lose Key.

For problem above, the utility model designs a kind of convenient assembly and disassembly key, and is difficult to lose the new key of key Key bow.

Utility model content

The utility model provides a kind of novel key ring, and more existing key ring more facilitates assembly and disassembly key, and is difficult to lose Lose key.

In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：

Novel key ring, including vortex-like ring, the vortex-like outside packing material of ring outer side edges make its outside edge profile be circle Shape, the vortex-like ring inner ring end sets annulus to center of circle direction, and the vortex-like ring is at its end and the position fitted with end It is respectively provided with the sawtooth of matches mutually.

Foregoing novel key ring, it is characterised in that the number of turns of the vortex-like ring is 2.

Foregoing novel key ring, it is characterised in that the vortex-like ring outer side edges profile radius are 12mm.

Foregoing novel key ring, it is characterised in that the annular radii is 4mm.

Foregoing novel key ring, it is characterised in that the material of the vortex-like ring is carbon steel.

Foregoing novel key ring, it is characterised in that the material of the sawtooth is PVC flexible glues.

The beneficial effects of the utility model are：When key is assembled and disassembled, annulus can be pulled, vortex-like ring inner end be opened, by key Spoon assembly and disassembly；When key loads key ring, because the presence of sawtooth, key is not easily disconnected from key ring, be difficult to lose key, this reality Novel with novel modeling, simple structure can be promoted the use of.

Brief description of the drawings

The utility model is further described with reference to the accompanying drawings and detailed description：

Fig. 1 is schematic diagram of the present utility model.

Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings：

Novel key ring, including vortex-like ring（1）, the vortex-like ring（1）The outside packing material of outer side edges makes its outside cincture Exterior feature is circle, the vortex-like ring（1）Inner ring end（11）To center of circle direction, annulus is set（12）, the vortex-like ring（1）At its end Portion and the position fitted with end are respectively provided with the sawtooth of matches mutually（13）.

Setting sawtooth makes key be not easily disconnected from key ring；The convenient assembly and disassembly key of annulus.

The number of turns of the vortex-like ring is 2.The vortex-like ring outer side edges profile radius are 12mm.The annular radii is 4mm. The material of the vortex-like ring is carbon steel.The material of the sawtooth is PVC flexible glues.

When key is assembled and disassembled, annulus can be pulled, open vortex-like ring inner end, key is assembled and disassembled；When key loads key ring, Because the presence of sawtooth, key is not easily disconnected from key ring, be difficult lose key, the utility model modern design, simple structure, Can promote the use of.

The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
