The utility model relates to a lock core, in particular to an anti lock core, which solves the problem of locking and preventing the lock from locking the core, including a lock shell, a turning wheel on the lock case, a jacket outside the lock shell, an inner sleeve, an inner core and a key, a inner sleeve connected with a lock shell sleeve, and a number of first bullet hole groups on the inner sleeve. An angle between a bullet hole group and the inner sleeve is composed of an angle of 45 to 180 degrees, an elastic component is set between the inner sleeve and the lock shell, the elastic component is fitted with the first bullet hole group, the inner core is set up with second bullet holes, the inner core is inserted into the inner sleeve and fixed with the dial wheel, and the inner core and the inner sleeve are arranged with the special shaped bullets and the second bullet hole groups. The elastic component is in touch with the end face of the special shaped bullet, with a large number of full copper parts and high service life. The structure consists of a trinity core structure consisting of a ball, a flat head and a spring wire. The key is difficult to rotate when the key is inserted, and the anti opening effect is good. At the same time, the key has no sharp structure. It is practical and safe.
【技术实现步骤摘要】
一种防拨锁芯
本技术涉及一种锁芯,特别涉及一种防拨锁芯。
技术介绍
市场上的传统锁芯均是长方体钥匙并在两面刻上牙花,或者为十字形柱体,前者较易拨动打开,而后者虽然安全系数略高,但因锁芯的设计导致钥匙结构较为尖锐,常常出现误伤事件。
技术实现思路
针对现有的技术不足,本技术提供一种防拨锁芯。为了实现上述目的,本技术所采取的技术方案是:一种防拨锁芯,包括锁壳,锁壳上设有可转动的拨轮,所述的锁壳外设有外套,且外套与锁壳过盈配合,还包括内套、内芯和钥匙,所述的内套与锁壳套接连接,且内套和锁壳通过紧定螺钉固定,所述的内套上设有若干第一弹孔组,第一弹孔组由若干直线排列的圆孔组成,相邻第一弹孔组与内套轴向构成夹角,夹角为45°至180°,内套与锁壳之间设有弹性组件,弹性组件与第一弹孔组配合安装,所述的内芯上设有第二弹孔组,第二弹孔组与第一弹孔组位置相对应,所述的内芯插入内套与拨轮配合固定,且内芯与内套之间设有异形弹子与第二弹孔组挡接配合,所述的弹性组件抵触异形弹子端面,所述的钥匙插入内芯,且钥匙与异形弹子配合固定。所述的弹性组件包括簧丝和异形平头,异形平头和簧丝一端固定连接,且簧丝另一 ...
