Description

展示物件的锁具结构
发明背景
1.发明的领域
本发明涉及一种锁紧展示物件的锁具，尤其是那种易于操作且便于良好保管的锁具。
2.相关技术的描述
人们经常需要锁紧展示物件，尤其是在公共展览中。通常使用带有通过一些可移动的物体弯成环的钢缆的锁具来实现这一目的。
如图5所示，用于这一目的的锁具通常包括一个锁体(50)，其设置有若干个号码轮(51)和一个用于可分离地承接卡掣部件(60)的窝槽(52)。在卡掣部件(60)前卡钩通过物件的一个定位孔之后或之前，要求将号码轮(51)转至预设的号码组合，以允许卡掣部件(60)盘状后端放入窝槽(52)中，并固定附加在锁体(50)上。
在锁体(50)的拨块(53)移动之前，通过再次将号码轮(51)转至预设的号码组而将锁具打开。此时，卡掣部件(6)可从锁体(50)上分离开。
在这种传统的锁具中，显然无论是将卡掣部件(60)固定在锁体(50)上还是使卡掣部件(60)脱离锁体(50)，都必须旋转号码轮(51)，这对于使用者来说是比较繁琐的操作。
此外，这种传统锁具不便于保管，因为分离的卡掣部件(60)经常容易丢失，这样余下的锁体(50)变得毫无用处。
发明概述
因此，本发明的目的就是提供一种锁紧展示物件的锁具，以减缓或消除上述问题。
发明内容
本发明的目的是提供一种易于操作的锁具。
本发明的另一目的是提供一种便于良好保管的锁具。
本发明的其它目的、优点和新颖的特点将通过下文结合附图进行的详细描述中更清楚地体现出来。
附图简介

图3为卡擎在图1中的锁具上的物品的横断面图；
图4为牢固附加在图1中的锁具上的物品的横断面图；
图5为背景技术中锁具的侧视图。
较佳实施例的详述
参看图1所示，本发明的锁具包括一外壳套(30)，其具有一前开孔(32)和一与开孔(32)邻接的卡钩板(33)，外壳套(30)的外周面附设一钢缆(36)。外壳套(30)还设有一个承接锁体(1)的后开孔(31)。
锁体(1)包括一个承接在外壳套(30)中的空心锁筒(10)。空心锁筒(10)具有一个后空腔(11)、一个与外壳套(30)中的前开孔(32)对齐的前穿孔(12)，以及优选限定于其中的一个纵长槽(14)。
锁芯(20)可移动地安装在锁筒(10)的后空腔(11)中。锁芯(20)具有一个用于承接固定销(15)的销孔(23)，所述固定销伸入纵长槽(14)内并可沿其移动，由此确保锁芯(20)相对于空心锁体(10)、并从而相对于外壳套(30)在图4所示的前位与图2、3所示的后位之间正确移动。
锁芯(20)还具有一个向前延伸的插销杆(21)，插销杆(21)的后端可转动地连接在锁芯(20)上，前端可转动地连接在锁闩(26)上。在图示实施例中，插销杆(21)的前端承接在锁闩(26)的后盲孔(261)中，并形成一由最前端圆板(25)限定而成的环槽(24)，一个定位销(27)穿过锁闩(26)的销孔(262)延伸入环槽(24)中，以允许插销杆(21)的前端可转动地连接在锁闩(26)上。
如图4所示，锁闩(26)上有一个可穿过前开孔(32)移出外壳套(30)的前凸板(263)。也就是，当锁芯(20)移动到前位时，前凸板(263)可以延伸出外壳套(30)并沿卡钩板(33)被牢固固定。当锁芯(20)在弹簧(28)的作用下移动至后位时，前凸板(263)也可缩进外壳套(30)内，所述弹簧容纳在空心锁体(10)的后空腔(11)内并围绕锁芯(20)的插销杆(21)安装。
在本发明的锁具中，还设置了用于在所述锁芯(20)移动到所述前位的同时将可松开地保持所述外壳套(30)的所述锁闩(26)的所述前凸板(263)的装置。
在一个更优选的实施例中，用于可松开地保持前凸板的装置包括一对限定于插销杆(21)外周上的相对的卡槽(22)，和一根承接在空心锁筒(10)的穿槽(13)内的簧条(17)。具体而言，穿槽(13)具有一对基本上在两个相对的切点处与前穿孔(12)相连的笔直段(131)，而簧条(17)被弯制成U形，并具有一对在穿槽(13)的笔直段(131)内可弹性变形的扣掣簧柄(171)。
这些扣掣簧柄(31)通常与插销杆(21)的外周面邻接，但是当锁芯(20)移动到前位时，就会迅速扣入卡槽(22)中，并且锁住插销杆(21)，由此保持锁闩(26)的前凸板(263)与外壳套(30)的卡钩板(33)并列。
参看图1和2，本发明的锁具可以简单地通过在锁体(1)固定至外壳套(3)之前将锁体(1)置入后开孔(31)中的方式进行组装，例如通过伸入外壳套(30)的对齐销孔(34、16)和空心锁筒(10)的卡销(35)。
这就意味着锁体(1)可从任何公知或未公知的独立锁具中进行选择，只要该锁具有一适合于部分地和可缩回地延伸出来的锁栓，尤其是那种通过按压锁芯使锁闩能够部分地和可缩回地延伸出来的锁具。换言之，本发明的锁具提供了多种锁体的选择，并且易于组装。
参看图2和3，本发明的锁具尤其供锁紧展示物件(40)之用。由图可见，物件(40)有一个定位孔(41)，外壳套(30)的卡钩板(33)能够延伸过该孔，以卡掣物件(40)。
参看图4，通过按压锁芯(20)能够锁住物件(40)，即通过将锁芯(20)从后位移动到前位的方式。在前位时，U形簧条(17)的弹性扣掣簧柄(171)能快速扣入锁芯(20)的卡槽(22)中，并在那锁住插销杆，由此保持锁闩(26)的前凸板(263)与外壳套(30)的卡钩板(33)并列。
现在，前凸板(263)保持在定位孔(41)中，并且阻止若非如此卡钩板(33)便会从定位孔(41)中脱离出来的路径。于是，展示物件就能被锁紧，直到锁具被打开。
只有通过相对于锁芯(20)转动插销杆(21)，例如将匹配钥匙(未示出)插入位于锁芯(20)中限定的钥匙孔中，锁具才能被打开。此时通过转动插销杆(21)，两扣掣簧柄(171)都被向外推开。当扣掣簧柄(171)完全滑出卡槽(22)并再度与插销杆(21)的外周面邻接时，锁芯(20)会在压缩弹簧(28)的作用下从前端位置(图4)快速地移动回到后端位置(图3)。
结果，锁闩(26)的前凸板(263)回缩进外壳套(30)，卡钩板(33)会从定位孔(41)中脱离出来，从而允许物件(40)同本发明的锁具分离开。
应该认识到，簧条(17)可制成其他形状，而不是制成U形。例如，还可使用一种制作成L形的具有单根扣掣簧柄的备择簧条。
在这种情形下，穿槽(13)可仅形成有一段笔直段，其基本在一个切点处与前穿孔(12)相连，而插销杆(21)上也可只有一个限定于其中的卡槽(22)。L形簧条安装在穿槽(13)中，单个扣簧柄在笔直段中可弹性变形。类似于U形实施例，单个扣簧柄通常邻接在插销杆(21)的外周面，但是当锁芯(20)移动到前位时，就会迅速扣入卡槽(22)中，并且锁住插销杆(21)。
从上面的说明中，可清楚地看出本发明具有如下优点：
1.易于操作：
由于物件(40)只需通过按压锁芯(20)就可被锁紧，所以本发明的锁具易于操作。
2.便于良好保管：
因为卡钩板(33)与外壳套(33)是一体成型的，并且无论如何也不会丢失，所以本发明的锁具便于良好保管。
3.具有多种锁体的选择：
因为可以从任何具有适于部分且可缩回地伸出的锁闩的独立锁体中进行选择，所以本发明的锁具可选择多种锁体。
4.易于组装：
因为可以简单地通过将卡销(35)插入两个对齐的销孔(34、16)中来将锁体(1)固定在外壳套(30)中，所以本发明的锁具容易组装。
然而应该认识到，尽管本发明的众多特征和优点都已经在上述说明中结合详细结构和发明的功能进行了阐述，但是所公开的内容只是示意性的，在由所附权利要求书所表达的术语的总体宽泛意义所表述的全文的本发明的原则内，可以在细节方面做出多种变化，尤其是在形状、尺寸和部件的布置方面。
