Abstract
The utility model relates to a small key accessory. The telescopic key chain comprises a key chain body, the key chain body comprises a self suspending part and a key suspending part, and the self suspending part and the key suspending part are connected by an extension device. One end of the extension device is connected with a pull rope, and the other end of the extension device is connected with the self suspending part. A reset rotating shaft is arranged in the extension device, and the pull rope is fixed on the reset rotating shaft. One end of the reset rotating shaft is connected with a reset spring. When people open a lock, a key is pulled out with the pull rope. When the lock is opened and the key is not used, the pull rope is wound on the reset rotating shaft as the reset rotating shaft rotates under the action of the reset spring, the pull rope is shortened, and the key is automatically fed into the extension device with the pull rope. Thus, the lock is conveniently and effectively opened.
Description
Technical field
The utility model relates to small-sized key accessory, is specifically related to a kind of key chain.
Background technology
Now, most of people are fixed on key on the key ring, then with key chain on the waist belt between waist, like this, when unblanking, just must must take off key from waist belt, very inconvenient; Also have because do not think that again taking off key from waist belt unblanks and connect a plastics spring.Though be the trouble of having avoided taking off key when unblanking, can owing to the retractility of plastics is bad, key must be put pocket into after not on waist belt, it is very dangerous that the sawtooth of key directly contacts thigh across trousers.Some then is directly key to be placed in the bag, or joins a key case, directly key is placed on the key case, and is very inconvenient when looking for key like this, may forget owing to careless sometimes.
The utility model content
The purpose of this utility model is, a kind of key chain that stretches is provided, and solves above technical problem.
The technical problem that the utility model solved can realize by the following technical solutions:
The key chain that can stretch comprises a key chain main body, and described key chain main body comprises that one self articulates part and a key articulates part, it is characterized in that, described self articulate partly and described key mounting part branch is provided with a stretching device between interconnecting;
One end of described stretching device connects a pull rope, and the other end connection of described stretching device is described self to articulate part.
Be provided with the rotating shaft that resets in the described stretching device, described pull rope is fixed in the described rotating shaft that resets.
One end of the described rotating shaft that resets connects a back-moving spring.
When people pull out from described stretching device with described pull rope at the key that described key is articulated part, unblank then, open when lock and to finish when not re-using key, under described action of reset spring, the described rotating shaft rotation that resets, described pull rope is looped around in the described rotating shaft that resets with the described rotating shaft rotation that resets, and described pull rope shortens, described key articulates the key of part just automatically along with described pull rope enters into described stretching device, makes like this to unblank not only to make things convenient for but also effective.
Self articulate part and be used for fixing, for example on the waist of trousers, wrap in the place of wanting to fix.The shape of described key chain main body can be doll shape or other shape, can be according to different requirements set.Like this, described key chain main body not only can be used to place key, can also serve as a kind of ornament, and is both beautiful and practical.
Beneficial effect: during the key chain of operative installations key,, very convenient in the process of unblanking because the utility model has adopted technique scheme.When unblanking, need not leave no choice but take off key chain because key reaches lockhole, also not be used in and also will place key after unblanking and feel trouble, taking off, putting well in the time of more can being not a succession of unblanking because of having a bad memory moved and key forgotten, solved a series of trouble with worried, used very convenient.
Description of drawings
Fig. 1 is an overall structure principle schematic of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, the key chain that can stretch comprises a key chain main body 1, and key chain main body 1 comprises that one self articulates part 2 and a key articulates part 3, self articulates part 2 and key and articulates part 3 and be provided with a stretching device 4 between interconnecting.One end of stretching device 4 connects a pull rope 5, and the other end connection of stretching device 4 self articulates part 2.Be provided with the rotating shaft 6 that resets in the stretching device 4, pull rope 5 is fixed in the rotating shaft 6 that resets.The end of rotating shaft 6 of resetting connects a back-moving spring 7.
When people pull out from stretching device 4 with pull rope 5 at the key that key is articulated part 3, unblank then, open when lock and to finish when not re-using key, under the effect of back-moving spring 7, rotating shaft 6 rotations that reset, pull rope 5 is looped around in the rotating shaft 6 that resets with rotating shaft 6 rotations that reset, pull rope 5 shortens, key articulates the key of part 3 just automatically along with pull rope 5 enters into stretching device 4, like this, makes and unblanks not only to make things convenient for but also effective.Self articulate part 2 and be used for fixing, for example on the waist of trousers, wrap in the place of wanting to fix.The shape of key chain main body 1 can be doll shape or other shape, can be according to different requirements set.Like this, key chain main body 1 not only can be used to place key, can also serve as a kind of ornament, and is both beautiful and practical.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
