Abstract

本实用新型提供一种五金产品,尤其是一种适用于保险箱中的旋转式电磁锁。它包括锁舌、连杆销、连杆、支架、锁盘、偏心轴、主轴、轴承、手轮、弹簧挡片、弹簧、衔铁、电磁铁、手轮轴。其最大特点是由于主轴装入轴承,当锁舌端面加上一外力,不能移动电磁铁或使其变形,因此,不能移动锁舌,也就能防止将保险箱箱门打开,故保险箱安全可靠。它能广泛地使用于保险箱及其他有关装置。

Description

旋转式电磁锁
本实用新型提供一种五金产品,尤其是一种适用于保险箱中的旋转式电磁锁。
传统的电子锁都用电磁铁启闭,它的主要方法是连杆上开缺口,电磁铁衔铁插在缺口中,此法虽然简单,但防破坏性较差,在锁舌端面施加一较大的轴向力,可通过连杆传到衔铁和电磁铁上,把其移位甚至破坏,然后把锁打开。
本实用新型的目的是提供一种旋转式电磁锁,它能防止在锁舌端面加轴向力移动电磁铁及衔铁而把锁打开。
为了达到上述目的,本实用新型首先设计一锁盘,锁盘为扁柱体,在锁盘侧面对应两侧开一缺口;然后选购由矩形软铁制成的电磁铁,在其内装有一圆柱形的衔铁,在衔铁外侧骨架上绕上多匝漆包线,衔铁中段与一弹簧挡片紧紧固定在一起,在弹簧挡片上部设置一弹簧,当无电流时,由于弹簧作用,衔铁伸出电磁铁而插入锁盘缺口中;在锁盘顶面上设置一偏心轴,为扁圆柱体,锁盘中心开孔并紧紧插入一主轴,并装在轴承中;再设计一连杆,其为长条形,一端开一腰形槽,它套在偏心轴上,另一端开一圆孔;再设计支架及连杆销,支架为U形,在其两边开若干孔,将连杆销穿过连杆后插入支架两边孔内并紧固;在支架上还有二锁舌:最后设计手轮,装在主轴上,因此,当外力强加到锁舌端面,其合力通过主轴,因主轴较紧,而不产生形变和位移,故而达到目的。上述各步按工艺装配。
本实用新型优点是能防止外力移动电磁铁而打开锁舌,故安全可靠。
说明书附图1为本实用新型的俯视结构示意图。
说明书附图2为本实用新型的主视结构示意图。
图中标号(1)为锁舌,(2)为连杆销,(3)为连杆,(4)为支架,(5)为锁盘,(6)为偏心轴,(7)为主轴,(8)为轴承,(9)为手轮,(10)为弹簧挡片,(11)为弹簧,(12)为衔铁,(13)为电磁铁,(14)为腰形槽,(15)为缺口,(16)为手轮轴。
本实用新型具体制作过程是:制作锁盘(5),在其两侧对应各开设一缺口(15),其中心开孔,设置主轴(7),将主轴(7)穿入轴承(8),另将手轮轴(16)一端插入轴承(8),另一端紧紧与手轮(9)固定,在锁盘(5)顶面上设置偏心轴(6),制作连杆(3),其一端开一腰形槽(14),将其套在偏心轴(16)上,另一端开一圆孔,再制作支架(4)及连杆销(2),支架为U形,两边开设若干孔,将连杆销(2)穿过连杆(3)有圆孔一端后两端紧紧插入支架(4)两边,支架(4)底边上装上两锁舌(1),选购电磁铁(13),在其内装上一衔铁(12),衔铁(12)外侧骨架绕上漆包线,中段有一弹簧挡片(10)并与其紧固,在弹簧挡片(10)上端有一弹簧(11),电磁铁(13)与支架(4)固定,上述各部安装调试即成。
