Prevent a type lock core

The utility model belongs to the technical field of the technique of lock core and specifically relates to a prevent a type lock core, has two lock shells being made by copper product or copper alloy or aluminum alloy and shaft coupling connecting rods that are become by carbon steel or stainless -steel, sets for the shaft coupling connecting rod is located the bottom of two lock shells utilizes the shaft coupling connecting rod to link between two lock shells. This prevent a type lock core adopts split type structure, increases the structural strength of middle part, prevents to break and the inefficacy when lock core from receiving the external force attack. 本实用新型涉及锁芯的技术领域，尤其是种防折型锁芯，具有由铜材或铜合金或铝合金制成的两个锁壳和由碳钢或不锈钢制成的根联轴连杆，设定所述联轴连杆位于所述两个锁壳的底部，两个锁壳之间利用联轴连杆相联接。该防折型锁芯采用分体式结构，加大中间部位的结构强度，防止锁芯受到外力攻击时折断而失效。
