Detailed Description

Fig. 1 is a structural diagram of an anti-drilling lock cylinder according to an embodiment of the present invention, and fig. 2 and 3 are combined; the utility model discloses prevent boring lock core, include: a lock core 1 and an anti-drilling cover 2; one end of the lock cylinder 1 is a key jack 10; the key insertion hole 10 is used to insert a key, thereby rotating the cylinder to perform an unlocking operation.

It should be noted that the anti-drilling cover in this embodiment is generally made of cemented carbide, stainless steel or a wear-resistant high-hardness material. Cemented carbide, an alloy material made by a powder metallurgy process from a hard compound of a refractory metal and a binder metal. Cemented carbide is widely used as a tool material, such as turning tools, milling cutters, planing tools, drill bits, boring tools and the like, for cutting cast iron, nonferrous metals, plastics, chemical fibers, graphite, glass, stone and common steel, and also for cutting refractory steel, stainless steel, high manganese steel, tool steel and other materials which are difficult to process.

The anti-drilling cover 2 is arranged on the key insertion hole 10; a plurality of mounting holes are formed in the side surface of the lock cylinder 1; the anti-drilling cover 2 is provided with a positioning pin 3 for being inserted into the mounting hole; the dowel pins are generally cylindrical pins, preferably having a taper.

The anti-drilling cover 2 is fixed on a key jack 10 of the lock cylinder 1 through the positioning pin 3.
