Description

Lock core envelope dual fail-safe lid formula anti-theft device

Technical field: the utility model relates to anti-theft device, is specially a kind of lock core envelope dual fail-safe lid formula anti-theft device.

Background technique: at present, what present automotive license plate and tire used is that standard bolt is fixed, this has brought potential safety hazard with regard to the use of giving tire, the phenomenon of losing of tire grows in intensity now, become numerous car owners' a worry, because what each tire used is standard bolt, then give thief with opportunity.

Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, with low cost, easy installation and removal, time-saving lock core envelope dual fail-safe lid formula anti-theft device.The purpose of this utility model is achieved in that it comprises anti-theft bolt (1), fixed lock core projection (2), anti-theft bolt internal tooth (3), groove (4), lock core spring base (5), retainer (6), lock core (7), special spanner (8), groove (9), retainer platform (10), standard spanner socket (11), key (12), annular space (13), groove (14), retainer retaining ring (15).Fixed lock core projection (2) is connected and fixed with fixed lock core projection (2), anti-theft bolt internal tooth (3) with annular space (13) back that anti-theft bolt internal tooth (3) is surrounded in groove (9) insertion anti-theft bolt (1) endosome on the special spanner (8).In an end of anti-theft bolt (1) up and down to two grooves (4) should be arranged.Fixed lock core projection (2), anti-theft bolt internal tooth (3) are corresponding one by one with the concaveconvex shape of groove (9).Lock core spring base (5) on the lock core (7) is connected and fixed in groove (4).The utility model has the advantages that: simple in structure, with low cost, easy installation and removal, manipulate easy to maintenance, each product all have corresponding special spanner and with the key duplicate protection of lock core one to one.

Description of drawings: Fig. 1 is the utility model anti-theft bolt structural principle schematic representation; Fig. 2 is the structural principle schematic representation of the utility model special spanner (8); Fig. 3 is the utility model retainer structural principle schematic representation; Fig. 4 is the structural principle schematic representation of the utility model lock core spring base and lock core (7); Fig. 5 is that the utility model fixed lock core projection, retainer platform, anti-theft bolt internal tooth are in anti-theft bolt interior profile linkage structure principle schematic; Fig. 6 is the linkage structure principle schematic of the utility model lock core spring base, groove and lock core section.Fig. 7 is that the utility model anti-theft bolt internal tooth, groove, lock core spring base, retainer (6), lock core are in anti-theft bolt section linkage structure principle schematic.

Embodiment: fixed lock core projection (2) is connected and fixed with fixed lock core projection (2), anti-theft bolt internal tooth (3) with annular space (13) back that anti-theft bolt internal tooth (3) is surrounded in groove (9) insertion anti-theft bolt (1) endosome on the special spanner (8).In an end of anti-theft bolt (1) up and down to two grooves (4) should be arranged.Fixed lock core projection (2), anti-theft bolt internal tooth (3) are corresponding one by one with the concaveconvex shape of groove (9).Lock core spring base (5) on the lock core (7) is connected and fixed in groove (4).Retainer platform and anti-theft bolt internal tooth are one.Special spanner and groove, standard spanner socket are one.The utility model connection procedure: hold the annular space insertion that special spanner surrounds trough aligned fixed lock core projection and anti-theft bolt internal tooth, tight a bolt.The extraction spanner is put into the retainer platform with retainer, and lock core passes retainer and inserts fixed lock core projection and the annular space that the anti-theft bolt internal tooth surrounds, and making the recesses coincide on fixed lock core projection and the lock core is one, and the retainer retaining ring is pushed down retainer.Turn key, the spring base on the lock core inserts groove.They are connected to one.When opening with key, key is inserted in the lock core, lock core is packed up the lock core spring base and is connected with the groove releasing, take out lock core, expose annular space, insert special spanner, groove on the spanner and fixed lock core projection, anti-theft bolt internal tooth are corresponding, then can turn bolt.The synchronous variation of ditch, groove and retainer platform, anti-theft bolt internal tooth on each wrench then is exactly the birth of a new lock.
