Abstract
The invention discloses a key chain. The key chain comprises a body, wherein an arc-shaped lock ring is arranged on the body, an opening is formed in the upper end of the arc-shaped lock ring, a lock bar is arranged on the body and used for sealing the opening of the lock ring, the lower portion of the lock bar is arranged in a lock groove in the body, the upper portion of the lock bar is exposed out of the body, the middle of the lock bar is rotationally connected with the body through a hinge pin, and an elastic device is arranged in the lock groove to press the lower portion of the lock bar to make the upper portion of the lock bar seal the opening of the lock ring. According to the key chain, due to the facts that the lower portion of the lock bar is arranged in the lock groove of the body, the upper portion of the lock bar is exposed out of the body, the middle of the lock bar is rotationally connected with the body through the hinge pin, and the elastic device is arranged in the lock groove to press the lower portion of the lock bar to make the upper portion of the lock bar seal the opening of the lock ring, the lock bar firmly locks the opening of the lock ring due to pressing of the elastic device in the lock groove, and the key chain cannot easily fall off.
Description
Technical field
The present invention relates to key chain.
Background technology
Key chain is the thing that almost everyone uses, and the key chain of prior art comprises body, and described body upper end is provided with the circular-arc lock ring of opening, and described body is provided with locking bar and seals described shackle openings.In use we find that locking bar is easily malfunctioning, cause key chain to come off.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of key chain of difficult drop-off.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of key chain, comprise body, described body upper end is provided with the circular-arc lock ring of opening, described body is provided with locking bar and seals described shackle openings, wherein locking bar bottom is located in the locked groove of body, described body is exposed on locking bar top, locking bar middle part is rotationally connected by bearing pin and body, body is provided with a vertical pin groove, described bearing pin can slide up and down along pin groove, in described locked groove, being provided with elastic device pushes described locking bar bottom and makes shackle openings described in locking bar closed upper part, described elastic device comprises is vertically located at the uprighting spring of described locked groove bottom and the horizontal spring that locked groove sidewall horizontal arranges.
As preferably, described locking bar upper end is provided with spherical institute head, and the corresponding described tapered end of described shackle openings end is provided with hemispherical fore shaft, at elastic squeezing unit effect lower lock head, snaps in described fore shaft.Can more effectively make locking bar pin shackle openings.
As preferably, described locking bar top is provided with the press head of an outstanding locking bar at tapered end downside.
As preferably, described press head is provided with convenient finger downwards and the cammed surface of exerting pressure to lock ring inner side.Press head is set to be convenient to sealing and to open lock ring.
Key chain locking bar of the present invention bottom is located in the locked groove of body, described body is exposed on locking bar top, locking bar middle part is rotationally connected by bearing pin and body, in described locked groove, being provided with elastic device pushes described locking bar bottom and makes shackle openings described in locking bar closed upper part, locking bar is subject to elastic device in locked groove to push firmly locked shackle openings, key chain difficult drop-off like this.
