The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As Figure 1-4, the utility model provides a kind of lock core anti-riot protective device, comprise lock core assembly 1, lock sleeve 2, interior anti-drilling lid 3, outer prizing-proof cover 4, rear pin 5 and front pin 6, described lock sleeve 2 is sleeved on lock core assembly 1, described outer prizing-proof cover 4 is sleeved on the leading section of lock sleeve 2, on described outer prizing-proof cover 4, be provided with an interior anti-drilling lid installing hole 41, in described interior anti-drilling lid installing hole 41, be movably set with an interior anti-drilling lid 3, on described interior anti-drilling lid 3, be provided with the key insertion hole matching with the lockhole of lock core assembly 1; Described lock core assembly 1, interior anti-drilling lid 3 and outer prizing-proof cover 4 is coaxial distributes with one heart, free to rotate after installing, can prevent that electric drill from boring bad lock core, also can prevent that screwdriver from prying open lock core simultaneously.Described rear pin 5 is fixing with the rear end riveted joint of lock core assembly 1 by lock sleeve 2 through lock sleeve 2 and lock core assembly 1 successively; Described front pin 6 is fixed the front end riveted joint of outer prizing-proof cover 4, lock sleeve 2 and lock core assembly 1 through outer prizing-proof cover 4, lock sleeve 2 and lock core assembly 1 successively.
Described lock sleeve 2 comprises the lower channel jacket 21 and the top cylindrical sleeve 22 that connect as one, and described top cylindrical sleeve 22 is positioned at the leading section top of lower channel jacket 21, and the length of described top cylindrical sleeve 22 is less than the length of lower channel jacket 21.Be that lock sleeve 2 one end surround lock core assembly 1 entirely by top cylindrical sleeve 22 and lower channel jacket 21, the other end is by lower channel jacket 21 by lock core assembly 1 semi-surrounding, and full one end surrounding is arranged on outdoors, prevents that twistlock device from twisting off lock core.In addition, the length of described lower channel jacket 21 and lock core assembly 1 equal in length, the length of lock core assembly 1 can be selected according to actual needs, changeable, and the structure of different lock core assemblies is all applicable to this device.
