Description
一种无钥匙盲开机械密码锁,属于机械密码锁技术领域。
目前,现有技术中的密码锁分为电子密码锁和机械密码锁,电子密码锁或智能锁类有指纹锁、卡片锁、虹膜、脸谱识别等。不可讳言,所有的电子密码锁或智能锁都有着一个共同弊症就是:电子化程度越高,可靠性越低。诸如火灾、潮湿气候环境、怕震动和静电冲击,怕电磁干扰;需要考虑市电还是电池的电源适配问题,技术开锁的教程和工具在网上随处贩卖,不法分子轻而易举便可掌握技术开锁的本领。综上所述,人们永远无法预测电子功能的失效在什么时候,也许就在下一秒,停电、短路、电子破解等随时让门锁形同虚设。
机械密码锁又包括钥匙开启的密码锁和不用钥匙开启的密码锁,特别是不用钥匙开启的机械密码锁,由于现有的机械密码锁机构限制,密码的变化规律过于单一,若对机械密码锁的结构有所了解,可通过侦听、操作的触感等方式,在有限次的试探中锁定密码并打开,如了解内部结构,通过多次反复尝试即可轻松打开密码锁。因此,一种结构简单、安全可靠,防盗性强的密码锁是目前亟待解决的问题。
本发明所要解决的技术问题是:克服现有技术的不足,提供一种结构简单、安全可靠,防盗性强的无钥匙盲开机械密码锁。
本发明解决其技术问题所采用的技术方案是:一种无钥匙盲开机械密码锁,其特征在于:包括立板、底板、转盘、插接盘和转轮轴,转盘和插接盘同轴套装在转轮轴上,转轮轴水平转动安装在立板上,转轮轴一端穿过立板且该端部转动套装有密码转轮,密码转轮内端部穿过立板并连接转盘;所述转盘靠近插接盘的内端面上设有水平设置的插销,插接盘上对应设有多个顺向插槽和逆向插槽;转盘一侧设有转盘定位机构,转盘外圆周端面上设有与转盘定位机构内侧对接的标记卡槽;插接盘与转盘相对的端面之间设有定位插板,定位插板底部固定连接底板,定位插板上环形设有多个插接孔,插销穿过相应的插接孔连接插接盘的顺向插槽或逆向插槽。
本发明改变了传统的机械密码锁的锁芯结构,采用同轴叠加的转盘和插接盘相互插接的形式,完成锁芯的开启和锁紧,转盘作为选择盘,插接盘作为被选择盘,转盘上设有水平设置的插销,插接盘上对应设有多个插槽,通过插销与插槽的插接关系,实现开启或关闭,为了提高机械密码锁的安全性和防盗性能插槽分为顺向插槽和逆向插槽,插销穿过定位插板连接插接盘,定位插板上设置多个插接孔,插接孔环形设置,与多个插槽对应设置,优选的,插接孔的个数多于插槽的个数,即,插销即存在可以***插槽的情况,也存在插销不能***插槽的情况。当不知道密码的开启者想要尝试开启机械密码锁时,如果插销对应的是逆向插槽,则插接盘会反转。
因为外观面板上没有了传统密码锁的刻度盘及刻度标识,代替方式变成了标记卡槽和弹性定位凸起,两者之间运动产生的有规律的卡顿触感,此时,非法开启者即使熟悉本密码锁内部结构,却又看不见的情况下,在面对插接盘中数圈插槽和若干个正、反向插槽时,将无所适从,只能凭记忆挨个试探,逐圈试探。本发明设计正确开启密码的位置颠倒错乱,无规律,可任意设置。如此,彻底打乱尝试开启密码锁的惯性思维,充分提高了密码锁任意开启的难度;同时,还在转盘一侧设置定位机构,只有定位机构与转盘上的标记卡槽对准并且找到对应的、正确的标记卡槽时,通过定位机构的配合,才能正确的***;特别的,本发明的密码锁在开启时,无论密码对错,其声音、触感均无差别,因此,非法开启者无法通过转动的声音或触感来判断密码的规律及是否正确,即使零距离偷窥也无从得知正确的开启位置。再者,顺向插槽和逆向插槽在插接盘上设置的位置及顺序是任意的,之间间距并不相同,可再一次提高密码锁的安全性和防盗性能。
所述的转盘包括外圈的圆环和放射状均布在圆环内的多条转盘筋条,所述插销一端水平固定在转盘筋条上。
设置多条转盘筋条的目的是,作为插销的备用安装位置,当一个位置的插销发生故障时,可在其他转盘筋条上安装插销。
所述的转盘筋条内部设有空腔,在转盘筋条两侧面上开有容许插销径向移动的调节长槽,空腔内安装带动插销径向移动的调节机构。
设置调节长槽的目的是,便于调节插销在转盘径向的位置,在关闭密码锁时,可将插销的位置调节到错误的位置,使得插销与插槽的位置完全错开,处在不同直径的圆环范围内,即时非法开锁者在猜到部分密码的情况下,从外部也无法将密码锁打开,只有将插销调整到设置的位置才能对应到正确密码的插接盘的位置上;再者,也可在插接盘上设置多圈插接槽,便于形成多组更复杂的密码,最大程度的提高密码锁的安全性。
调节机构为齿轮齿条传动机构,包括安装在转轮轴上的齿轮和竖置在转盘筋条内腔的齿条,齿条上部固定连接插销,下部啮合齿轮。
优选的,插接盘可设有内外同轴套装的多组顺向插槽和逆向插槽,转盘外圆周端面上对应设有多圈标记卡槽。
所述的插接盘上设有多组顺向插槽和逆向插槽,顺向插槽和逆向插槽均为带有斜面的凹槽,顺向插槽和逆向插槽的倾斜方向相反。
顺向插槽和逆向插槽的倾斜方向相反,使得插销进入顺向插槽带动插接盘正转,插销进入逆向插槽带动插接盘反转,避免在不知道密码的情况下多次尝试开启密码锁。
所述的顺向插槽的个数与所设置的密码的位数相一致。
所述的转盘定位机构包括定位支架、转轴、定位转轮和偏心定位滚轮,定位支架为扇形设置,同轴设置在转盘一侧,转轴一端部穿过立板并连接定位转轮,转轴中部设有偏心定位滚轮,转轴另一端部穿过定位支架连接限制其转动角度的限位机构,偏心定位滚轮上带有切平面,所述定位支架靠近转盘的端部上设有弹性定位凸起,弹性定位凸起一端与所述标记卡槽卡接,另一端设有定位弹簧,定位弹簧弹性连接偏心定位滚轮。
偏心定位滚轮上带有切平面,通过转动转轴及转轴中部安装的偏心定位滚轮,使得带有切平面的偏心定位滚轮压制弹性定位凸起,迫使弹性定位凸起的内端部压紧在转盘外缘周端面上,从而便于找到合适的标记卡槽并与之扣合。
所述的转盘定位机构可绕转盘设有多组,每一组均设有弹性定位凸起。多组转盘定位机构结构设置完全相同,户主任意选择其中一组均可以根据设定的密码规律找到与正确插接槽相对应的标记卡槽,转盘定位机构设置多组的目的是混肴视听,起到误导随意开锁者的目的,进一步提高密码锁的安全性。
所述的标记卡槽包括多组,标记卡槽的组数与所设密码的位数相一致,每位密码分别对应设定的一组标记卡槽。
所述的插接盘的外缘设有复位机构,复位机构包括复位杆、复位支架及安装在复位支架内部的复位滑块和复位弹簧,复位滑块设有左右两组,两组复位滑块中部之间连接有复位压簧,尾部伸出复位支架,复位支架外部设有固定块,固定块设置在两组复位滑块尾部之间。
在被多次随意转动之后,转盘和插接盘已经不知处于什么位置时,可通过复位机构将插接盘复位,恢复到初始位置,便于利用正确的密码快速的开启密码锁。
所述的两组复位滑块尾部连接并带动两组相向移动的拉紧机构,拉紧机构包括上滑轮、拉绳、绳轮和绳轮支座,绳轮支座固定在底板上,绳轮支座上转动安装绳轮,拉绳一端缠绕在绳轮上,另一端绕过安装在插接盘端面的上滑轮后分别连接两复位滑块尾部。也可在立板上安装复位转轮。
在非法开启过程中,顺向、逆向插槽及复位机构在发生动作时无论是声音还是触感均无差别,即使非法开启者在开启过程中拉动或转动复位机构,使得复位机构实现复位,非法开启者也觉察不到这一动作对应的密码锁内部的插槽是顺向还是反向的。从而确保非法开启者无法通过诊听、感触、数字逻辑分析等判断手段来开启本发明的机械密码锁。
与现有技术相比,本发明所具有的有益效果是:
本发明的机械密码锁可作为民用,解决了民用锁携带钥匙、忘记或丢失钥匙的诸多不安全弊端及麻烦。解决了银行金库、保险柜等特殊场合或设备使用中,现有密码锁开启关闭繁琐、保险系数低的弊端,提高了安全性能。本发明去除了传统密码锁外观面板上的刻度盘及刻度表示,利用零件之间滑动中的卡顿的触感来确定开启密码。本发明密码设置保管权交予用户,通过户主自己任意设置来做到绝对的信息安全。
本发明改变了传统的机械密码锁的锁芯结构,采用同轴叠加的转盘和插接盘相互插接的形式,完成锁芯的开启和锁紧,转盘作为选择盘,插接盘作为被选择盘,转盘上设有水平设置的插销,插接盘上对应设有多个插槽,通过插销与插槽的插接关系,实现开启或关闭,为了提高机械密码锁的安全性和防盗性能插槽分为顺向插槽和逆向插槽,插销进入顺向插槽带动插接盘正转,插销进入逆向插槽带动插接盘反转,即,当不知道密码的开启者想要尝试开启机械密码锁时,如果插销对应的是逆向插槽,则插接槽反转,彻底打乱尝试开启密码锁的惯性思维,充分提高了密码锁任意开启的难度;同时,还在转盘一侧设置定位机构,只有定位机构与转盘上的标记卡槽对准并且找到对应的、正确的标记卡槽时,才能正确的***,通过定位机构的配合,可再一次提高密码锁的安全性和防盗性能。

实施例
1
参照附图1:一种无钥匙盲开机械密码锁,包括立板1、底板2、转盘6、插接盘7和转轮轴5,立板1与底板2垂直连接形成安装支架,转盘6和插接盘7同轴套装在转轮轴5上,转轮轴5水平转动安装在立板1上,具体的,转轮轴5一端穿过立板1,另一端固定连接背板14;转轮轴5一端穿过立板1且该端部转动套装有密码转轮3;转盘6靠近插接盘7的内端面上设有水平设置的插销12,插接盘7上对应设有多个顺向插槽703和逆向插槽701;插接盘7与转盘6相对的端面之间设有定位插板13,定位插板13底部固定连接底板2,定位插板13上环形设有多个插接孔1301,插销12穿过相应的插接孔1301连接插接盘7。
插销12穿过定位插板13连接插接盘7,当定位插板13上设置多个插接孔1301,插接孔1301环形设置,与多个插槽对应设置,优选的,插接孔1301的个数多于插槽的个数,即,插销12即存在可以***插槽的情况,也存在插销12不能***插槽的情况。
定位插板13用于限定插销12的定向***,如果没有定位插板13的静止固定,转盘6向前推进,插销12即使插进插接盘7里面的插槽,转盘6就会随插槽转动,一反一正拧两下密码锁就会打开。定位插板13的作用是限制插销12必须在固定的位置插进插槽内,推动插接盘7实现正反转。
顺向插槽703和逆向插槽701仅为表述两种不同方向的插槽的相对位置关系和反向设置的特性,并不代表一定是正确的密码锁开启插槽的设置方向,正确的插接槽即可为顺时针方向设置,也可为逆时针方向设置,错误的插槽即为反向设置的插槽。
插销12进入顺向插槽703带动插接盘7正转,插销12进入逆向插槽701带动插接盘7反转;转盘6一侧设有转盘定位机构11,转盘6外圆周端面上设有与转盘定位机构11内侧对接的标记卡槽601。标记卡槽601包括多组,从多组标记卡槽601中任意选择几组作为设定标记,选择的标记卡槽601的组数与密码的位数相一致,即密码为几位,就选择几组标记卡槽601作为标识,每位密码分别对应设定的一组标记卡槽601。标记卡槽601的设置可按照某种规律来进行设置,如,每组标记卡槽601所包含的槽孔的个数不同,通过操作时的卡顿触感来判断是否为设定的标记卡槽601。
转盘6包括外圈的圆环和放射状均布在圆环内的多条转盘筋条603,插销12一端通过水平固定在转盘筋条603上。设置多条转盘筋条603的目的是,作为插销12的备用安装位置,当一个位置的插销12发生故障时,可在其他转盘筋条603上安装插销12。
设置调节长槽602的目的是,便于调节插销12在转盘6径向的位置,在给密码锁关闭时,可将插销12的位置调节到错误的位置,使得插销12与插槽的位置完全错开,处在不同直径的圆环范围内,即时非法开锁者在猜到部分密码的情况下,从外部也无法将密码锁打开,只有将插销12调整到设置的位置才能对应到正确密码的插接盘7的位置上;再者,也可在插接盘7上设置多圈插槽,便于形成多组更复杂的密码,最大程度的提高密码锁的安全性。
插接盘7上设有多组顺向插槽703和逆向插槽701,顺向插槽703和逆向插槽701均为带有斜面的凹槽,顺向插槽703和逆向插槽701的倾斜方向相反。顺向插槽703的个数与所设置的密码的位数相一致。
转盘定位机构11包括定位支架1101、转轴1103、定位转轮1105和偏心定位滚轮1106,定位支架1101为扇形设置,同轴设置在转盘6一侧,定位支架1101上设有与转轮轴5平行设置的转轴1103,转轴1103一端部穿过立板1并连接定位转轮1105,转轴1103中部设有偏心定位滚轮1106,转轴1103另一端部穿过定位支架1101连接限制其转动角度的限位机构,偏心定位滚轮1106上带有切平面,定位支架1101靠近转盘6的端部上设有弹性定位凸起1108,弹性定位凸起1108一端与标记卡槽601卡接,另一端设有定位弹簧1107,定位弹簧1107弹性连接偏心定位滚轮1106。
插接盘7的外缘设有复位机构10,复位机构10包括复位杆1001、复位支架1002及安装在复位支架1002内部的复位滑块1003和复位弹簧1004,复位滑块1003设有左右两组,两组复位滑块1003中部之间连接有复位压簧1004,尾部伸出复位支架1002,复位支架1002外部设有固定块1005,固定块1005设置在两组复位滑块1003尾部之间。
两组复位滑块1003尾部连接带动两组相向移动的拉紧机构9,拉紧机构9包括上滑轮901、拉绳902、绳轮903和绳轮支座904,绳轮支座904固定在底板2上,绳轮支座904上转动安装绳轮903,拉绳902一端缠绕在绳轮903上,另一端绕过安装在插接盘7端面的上滑轮901后分别连接两复位滑块1003尾部。在需要复位时,拉动缠绕在两复位滑块1003尾部上的拉绳902一端部,拉绳902同时拉动两复位滑块1003尾部向中间移动,两复位滑块1003头部夹紧复位杆1001,并在固定块1005的限制下,将复位杆1001恢复至设置的初始位置。拉绳902可拉动的端部可伸出密码锁壳体外部,也可采用其他方式嵌入在壳体内部,拉绳902可拉动的端部伸出密码锁壳体外部时,可相应在壳体上,如本实施例中的立板1上设置连接拉绳902该端部的转轮,通过转动转轮来实现拉绳902的拉紧或放松。
工作过程与工作原理:在开启本申请的密码锁时,需要确定插接槽处于初始位置,转动转盘定位机构11的定位转轮1105,确定偏心定位滚轮1106上的切平面压制弹性定位凸起1108,迫使弹性定位凸起1108的内端部压紧在转盘6外缘上,转动密码转轮3,使其带动转盘6转动,从而便于找到合适的标记卡槽601并与之扣合,根据密码的数字转动密码转轮3,转到正确的标记卡槽601的数字时,转盘定位机构11的弹性定位凸起1108扣在对应的标记卡槽601内,此时,推动密码转轮3,通过密码转轮3推动转盘6向插接盘7靠近,此时,插销12通过插接孔1301***顺向插槽703,插接盘7正向转动一个角度;再次通过密码转轮3拉动转盘6使其恢复原位,使得插销12脱离与插接盘7的连接,再次转动密码转轮3,从而便于找到下一正确的标记卡槽601并与之扣合,由此,再次确定下一位正确的密码。由此,多次反复操作,可根据已知密码打开密码锁。
非法开启者在面对插接盘中数圈插槽和若干个顺向、逆向插槽时,其中顺向插槽703只有数个、其余逆向插槽701个数是顺向插槽703的数倍乃至数十倍;此时非法开启者将无所适从,只能凭记忆挨个试探、逐圈试探。
插接盘7中设置的插槽为若干圈,每一圈正逆向插槽701若干个,顺向插槽703在插接盘7中的位置、顺序可任意颠倒分布,开启示意图:
4
3 2 1 0 1
2 3 4
负—————0————— 正
当第一次猜错,复位杆1001倒退至负1,继续错,继续退,直到退至负4。第一次猜对,第二次未必猜对,第二次猜错,复位杆1001退回至0,继续错,继续退。第一二次猜对,第三次猜错, 退回,继续错,继续退。第四次猜错,退回,再错再退,直至退回到负4。
非法开锁者开启传统机械密码锁依靠的是诊听和触感,本发明针对这一问题,采用的技术方案是——插销接触并推动顺向插槽703或逆向插槽701时声音相同,转盘6、复位杆1001无论在正反哪一个方向,复位时复位机构10动作、声音相同。
在非法开启过程中,顺向、逆向插槽及复位机构10在发生动作时无论是声音还是触感均无差别,因此,非法开启者无法通过诊听、感触、数字逻辑分析等判断手段来开启本发明的机械密码锁。简言之;本密码锁所设插槽之正反排列不在数字、数学逻辑概念之中,非法开启者即使熟知本密码锁内部结构,试图通过猜测、分析判断开启本密码锁都是徒劳。
实施例

插接盘7可设有内外同轴套装的多组顺向插槽703和逆向插槽701,转盘6外圆周端面上对应设有多圈标记卡槽601。转盘筋条603内部设有空腔,在转盘筋条603两侧面上开有容许插销12径向移动的调节长槽602,空腔内安装带动插销12径向移动的调节机构。调节机构为齿轮齿条机构8,包括安装在转轮轴5上的齿轮802和竖置在转盘筋条603内腔的齿条801,齿条801上部固定连接插销12,下部啮合齿轮802。
转轮轴5为空心轴,转轮轴5内套装插销调节转轴4,插销调节转轴4一端伸出密码转轮3,另一端连接竖向固定的背板14,背板14底部固定连接底板2。转轮轴5分为两段,一段依次穿过密码转轮3、立板1和转盘6,并且该段转轮轴5的内端固定连接转盘6的一侧外端面,另一段转轮轴5依次穿过定位插板13和插接盘7后连接背板14,插接盘7可在该段转轮轴5上转动,插销调节转轴4连接安装在转盘6内腔的齿轮802。
转动插销调节转轴4带动齿轮802一起转动,齿轮802与齿条801发生啮合,带动齿条801竖向移动,从而带动其上部连接的插销12的径向移动。转盘筋条603里面的插销12在做径向移动时,齿条801上面有定位盲孔的,纵向筋条转盘上面有钢珠在弹簧压力下,顶入齿条801上面的定位盲孔;作用于齿条801上下移动时的定位;因为,插接孔1301和插接盘7的插槽是多圈的,所以插销12的径向移动需要准确定位。通过调整插销12的径向位置实现对不同密码的开启,其他设置和工作原理与实施例1相同。
实施例

转盘定位机构11可绕转盘6设有多组,每一组均设有弹性定位凸起1108。转盘定位机构11设置多组的目的是混淆视听,起到误导非法开锁者的目的,多组转盘定位机构11采用完全相同的结构设置无论转动哪一组,都具有相同的卡顿触感,如果不知道密码,就无法通过操作的触感来判断,只有密码锁的用户,在知晓密码的前提下,任意选择一组转盘定位机构11都可以按照事先设定的标记卡槽601找到插销12正确的插接位置,实现插销12和插槽的正确插接,进一步提高密码锁的安全性。其他设置和工作原理与实施例1相同。
以上所述,仅是本发明的较佳实施例而已,并非是对本发明作其它形式的限制,任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型,仍属于本发明技术方案的保护范围。
