Baseball shape automobile steering lock with plastic sheath

Technical field

The utility model relates to a kind of automobile steering lock, refers in particular to a kind of baseball shape automobile steering lock.

Background technology

Traditional baseball shape automobile steering lock is made up of lock housing, lock core, dead bolt, ratchet device, handgrip usually, owing to lacked the protection of plastic sheath, plastic sheath and lacked the supporting of thrust ball bearing, cause its barrier propterty relatively poor, rotate dumb, the deficiency that bending strength is low.

The utility model content

It is good that the technical problems to be solved in the utility model provides a kind of barrier propterty, rotates flexibly the baseball shape automobile steering lock with plastic sheath that bending strength is high.

The technical solution of the utility model is such: a kind of baseball shape automobile steering lock with plastic sheath, comprise lock housing, be enclosed within the plastic sheath on the lock housing cylindrical, be installed in the lock core and the thrust ball bearing that is installed in the lock housing other end of lock housing one end end, in lock housing, be provided with dead bolt, one end of dead bolt is connected with handle stem, and links into an integrated entity by thrust ball bearing and lock housing, and the other end is connected with lock core by ratchet device; Lock housing, lock core, dead bolt, thrust ball bearing and handle stem are positioned on the same axis, and wherein said handle stem can only be around rotational, but can not be free to slide along axis, tighten at the cylindrical of handle stem and are with spongiform handgrip; On described plastic sheath, have the sheath breach, on the periphery of sheath breach, be provided with inner convex platform, and in the shell breach of inner convex platform insertion lock housing, plastic sheath is fixed on the cylindrical of lock housing; Be provided with plastic sheath at described dead bolt middle part surface.

After the utility model adopts said structure, protection by plastic sheath, plastic sheath has realized anticollision, the purpose that anti-scratch is decreased, handle stem is connected by thrust ball bearing and lock housing, has realized the purpose that handgrip rotates flexibly, the bending strength of lockset strengthens.
