Description
Technical Field
The utility model relates to a high carbon plastic padlock lock core belongs to tool to lock accessory field.
Background
At present, padlock lock core on the market is mostly that the metal is made, generally adopts the section bar, obtains required lock core through the machining after, and the processing cost is higher, because the restriction of processing equipment, a lot of key points can't obtain through machining in addition, and one is: the height of one end of the vertical milling bullet sinking groove is very low, so that the vertical milling bullets easily slide out to cause the separation of the lock cylinder and the lock tongue, which is one of the reasons why many padlocks are easily pried or broken; secondly, the transmission block of lock core, the transmission face of conventional transmission block is single inclined plane only, because through rotatory transmission, leads to the transmission not smooth.
