In order to prevent that glasses from being stolen, extension bar with lock is of a great variety on the market, though on the extension bar profile with lock of each manufacturer production difference is arranged all, have plenty of with unlike materials such as plastics and metals, but general structure all is consistent, relies on " guide rod traction " that is:, is equipped with locking device to trigger traction, close thereby form to close, prevent that glasses from being stolen.The towed glasses of the guide rod of prior art are hung bar, by a guide rod that a plurality of inverted "L" shaped crotches are housed and one a plurality of pressure pins that are used to bear the nose bridge position being housed forms, spring and locking device are housed under the guide rod, when opening lock, trigger spring, move up and down to form to close by guide rod and close with pressure pin.

But the towed glasses of the guide rod of prior art are hung the shortcoming that there are following two aspects in bar:

If after opening lock, inverted "L" shaped crotch can not be retracted to fully to be hung in the bar, thereby when needing to take out glasses, need double to note, otherwise glasses might run on the inverted "L" shaped crotch, easily glasses is bumped flower or scratch;

Because guide rod triggers spring by lock, thereby when using the extension bar to begin most, when unblanking, guide rod can be upspring suddenly, is easy to damage glasses like this, only hangs bar after a period of time in use, and guide rod could smoothly be upspring.

The utility model content

For solving the problem that prior art exists, the utility model provides a kind of can not damage glasses, glasses scalable with lock easy to use, attractive in appearance are hung bar.

The utility model is achieved in that

A kind of scalable glasses with lock are hung bar, described extension bar comprises hangs the bar main body, the straight-tooth slide bar, link, geared system, the straight-tooth slide bar of at least one is set on the described extension bar main body, fasten mutually between the straight-tooth slide bar, be connected with link and geared system on each straight-tooth slide bar, link is fixed on to be hung in the bar main body, the straight-tooth slide bar is connected by geared system with link, geared system comprises gear and ring gear, gear is meshing with each other with straight-tooth slide bar and ring gear respectively, and described link comprises two parts shell of mutual fastening, and the passage of ring gear operation is arranged between two parts shell, the straight-tooth slide bar lower end of least significant end is provided with trigger, and trigger is connected with air spring with lock respectively.

When closed if desired, rotational lock core, locking device trigger gas spring, after air spring was upspring, trigger was given the straight-tooth slide bar with transmission of power, and the straight-tooth slide bar vertically moves, and driven gear rotation, the gear driven ring gear is toward inner rotary, and ring gear inserts in two parts shell, thereby realizes the state of the closure of glasses extension bar.During folding, air spring shrinks, and the straight-tooth slide bar moves down, and the driven gear rotation, and the gear driven ring gear inwardly shrinks, and is retracted to and hangs the bar body interior, the unlatching that realizes hanging bar.

Optionally: the outer link of described extension bar main body is the quarter turn arc.

The glasses scalable with lock that the utility model provides are hung bar and are had the following advantages:

(1) opens when hanging bar ring gear and be retracted to fully and hang in the bar, can not damage during the taking and placing glasses or scratch glasses;

(2) cooperatively interact by geared system and straight-tooth slide bar, the dynamics that makes arrives each glasses link fifty-fifty, thereby the synchronization that the eyes link that makes glasses hang the top of bar and bottommost triggers at trigger ejects or withdrawal simultaneously.
