The utility model content

Content of the present utility model is to have remedied the defective in the prior art, and a kind of concealed core type automobile steering lock is provided, and its keyhole is hidden in the inboard, is not easy to pry open, and has played excellent antitheft function.

The utility model is realized by following scheme:

A kind of concealed core type automobile steering lock includes the lock body of key and clavate, and it is characterized in that: the lock body left end is provided with the lock core passage, and lock core is fixedly arranged in the lock core passage; The lock core left end is provided with locking bolt, and right-hand member is provided with keyhole; The position of corresponding lock core passage has two loop bar holes on the described lock body, is with U-shaped loop bar in the loop bar hole, and the insertion end that the right bar of loop bar nestles up lock core and right bar is provided with the locking bolt hole that a row cooperates with locking bolt; The right side that is positioned at lock core on the described lock body is provided with the key open slot of L type, has the keyhole corresponding with keyhole position on the lock core on the sidewall of key open slot and inserts mouth; Key includes the shank of the key of L type, and the front end of shank of the key fixedly has the key bit portion that cooperates with lock core; Described key inserts the key open slot, and key bit portion passes keyhole and inserts in mouthful back insertion key eye, and forward and backward screw key is then realized locking bolt turnover locking bolt hole.

A kind of concealed core type automobile steering lock is characterized in that: described lock body left end fixed cover is equipped with the loudspeaker pressure head corresponding with loudspeaker position on the vehicle steering.

A kind of concealed core type automobile steering lock is characterized in that: described key bit portion is triangular facet shape.

A kind of concealed core type automobile steering lock is characterized in that: the port of lock core passage fixedly has plug.

A kind of concealed core type automobile steering lock is characterized in that: the position on the crooked position of described loop bar, the lock body between loop bar and lock body two ends are respectively installed with sheath.

A kind of concealed core type automobile steering lock is characterized in that: the shank of the key rear end of described key is set with sleeve; The shank of the key rear end also is provided with the key annular distance.

The utility model can select different locking bolt holes corresponding with locking bolt according to the size of bearing circle diameter, controls the gap between loop bar and the bearing circle, to guarantee the theftproof performance of lockset.

Concrete principle of work of the present utility model is:

The utility model inserts the key open slot with key after loop bar packages bearing circle, key bit passes keyhole and inserts in mouthful back insertion key eye, and forward and backward screw key is then realized locking bolt turnover locking bolt hole.When locking bolt comes out, just enter the locking bolt hole, thereby pinned bearing circle.Meanwhile, the loudspeaker pressure head of lock body left end has also been pushed down loudspeaker, the next door object of lock body right-hand member retaining bearing circle in car, make bearing circle not rotate arbitrarily and drive, moreover can report to the police because of the left end loudspeaker pressure head lane sound loudspeaker of lock body again once moving lockset slightly, this shows to the utlity model has that keyhole is hidden anti-strand, key open slot angle is limited and the lockset of not opening, the loudspeaker pressure head does to ring these multiple anti-theft featuries of loudspeaker again at any time easily.

Sheath in the utility model has all played protective effect and has made objects such as car loudspeaker bearing circle not be worn and made a mess of.

Key in the utility model, it or not usual straight type key, key bit portion is multiaspect, type such as triangular form or cross etc., so structure has not only increased the size of key of key, and mutual opening rate reduces, and can effectively prevent from illegally unblanking, more strengthened the fastness of key, with the preceence of the overall quality that ensures lockset.

The utility model has the advantages that:

The utility model is to utilize the restriction of hiding lock core and keyhole and the angle of unblanking, actv. has been controlled the feasibility opereating specification of unlocking tool and the violence strand sled of master key reamer class instrument, moreover lock body loop bar of the present utility model all is that solid round steel is more solid firmly, the utility model is not only the structural advantage of lock body lock core, has strengthened the difficulty that violence is unblanked more thereby also make the corresponding anti-saw of quenching stiffened processing shearing resistance on its loop bar.
