Detailed Description
The utility model discloses magnetic force self-lock device mainly uses in the theftproof articles for use field for install on the theftproof of high-end toy or other stereoplasm article that have the blind hole, the reinforcing prevents losing the theftproof effect.
As shown in FIG. 1; the utility model discloses magnetic force self-lock device of embodiment includes: the magnetic ball comprises a shell 1, a magnetic ball 2 and a spring clip 3; the present embodiment mainly uses a plastic housing and a cylindrical structure of the magnetic ball.
The shell 1 is a cylindrical closed shell, and the magnetic ball 2 is slidably mounted in the shell 1; the housing is generally cylindrical in configuration.
One end of the shell 1 is provided with a butt joint which is used for being inserted into a blind hole or a special matching and sleeving joint. Two symmetrical jacks are arranged on the butt joint; two ends of the spring clamp 3 are respectively arranged in the two jacks; the middle part of the spring clip 3 is an elastic sheet; the two ends of the spring clip 3 can compress the elastic sheet under pressure to approach each other.
A guide post 20 is arranged at one end of the magnetic ball 2 along the sliding direction, and the elastic sheet is sleeved on the guide post 20; the magnetic ball 2 slides in the housing 1 to drive the guide post 20 to pull the elastic sheet, so that the two ends of the spring clip 3 are retracted inwards from the insertion hole.
When the self-locking device of the utility model is applied to the anti-theft article, the locking can be completed only by inserting one end of the butt joint into the article to be locked; the docking head may fit a dedicated socket or a dedicated blind hole. Due to the elastic action of the spring clip, after the spring clip is inserted, the spring clip expands to automatically realize the clamping and locking action.
The magnetic ball 2 can slide towards one side of the butt joint under the action of external magnetic repulsion force, so that the spring clamp can automatically contract and deform and then retract from the jack to release the locking state, and the technical problem of accidental opening is avoided.
