Description

一种锁止装置及具有其的行李箱 技术领域
本发明涉及生活用品技术领域，具体涉及一种锁止装置及具有其的行李箱。
背景技术
在箱具领域，分为固定容积和可变容积两种。对于前者，箱具内部的使用空间大小固定，不能根据实际需要来改变箱具内部的存放空间，而且箱具(尤其是行李箱)的使用频率较低，大多时候都处于闲置状态，对于无法改变大小的箱具而言，其会占用一定的置放空间，不便于箱具的存放。
而对于后者，其可以根据实际存放的需要来改变箱具内部的存放空间，以使箱具的实用性更好，但是对于目前可变容积的箱具而言，其主要是在原有箱具的基础上增加可拆卸安装的箱体，两者再通过锁止结构连接在一起，例如授权公告号为CN208114187U、名称为《一种可调节大小的行李箱》的申请案中，其通过拉链方式的锁止结构来实现活动箱体与顶部箱体、底部箱体之间的连接，这种方式在实际使用中操作不够便捷、省力。
发明内容
本发明的目的在于提供一种锁止装置及具有其的行李箱，不仅锁止装置的操作更加便捷、省力，而且也便于行李箱根据实际需要来改变其大小。
为实现上述目的，本发明采用以下技术方案：

优选地，所述按钮的背面设有连接座，所述连接座上转动设置有铰接件，所述拉绳的下端转动地连接于所述铰接件上。
优选地，所述拉绳下端的端部设有下连接头，所述下连接头转动地连接于所述铰接件上，所述下连接头上设有第一挡块，所述壳体的侧边形成有延伸部，所述延伸部上设有与壳体内部相通的凹槽，所述凹槽上设有沿其长度方向的定位槽，所述下连接头穿设于凹槽中，并使所述第一挡块沿着定位槽移动。
优选地，所述锁止座包括第一座体和第二座体，所述第一座体上设有安装槽和安装孔，所述止推件设于安装槽中，所述拉绳的上端穿过安装孔后与止推件相连接，所述第一座体往侧边延伸形成所述第二座体，所述第二座体上设有所述容置腔，且所述容置腔与安装槽相通。
优选地，所述锁销包括销本体和止顶部，所述销本体的顶部设有止推口，所述止推件抵接于止推口上，所述销本体往侧边延伸形成所述止顶部。
优选地，所述止推口的截面形状呈三角形，所述止推件下端的形状与止推口的形状相适应，所述止推件的侧边分别延伸形成有第二挡块和连接部，所述第一座体于第二座体的一侧设有限位槽，所述第二挡块在限位槽中移动，所述拉绳活动穿设于连接部中，并在其顶端设有上连接头。
优选地，所述第一座体往侧边延伸形成有若干个所述第二座体，所述第一座体上设有与第一座体数量相对应的安装槽，各所述第二座体上均设有容置腔，所述容置腔分别与安装槽相通，所述容置腔内均设有锁销和第一弹簧，所述止推件的数量与第一座体的数量相对应，且各所述止推件的连接部连成一体，各所述止推件分别抵接于所述锁销的止推口上。
优选地，所述壳体的前侧设有用于安装按钮的安装口，所述壳体的后侧设有用于封闭其的壳盖，所述壳体内设有若干立柱，所述壳盖固定于立柱上。
一种行李箱，包括下箱体、上箱体及上述的锁止装置，所述下箱体上设有下锁孔，所述上箱体于与下锁孔同一平面的位置上至少设有两个上锁孔，所述锁止装置设于下箱体的内侧壁上，且所述锁止装置的锁销伸入下锁孔中， 并插入其中一个所述上锁孔中，以将所述下箱体和上箱体连接在一起。
进一步地，所述下箱体上设有滑轨，所述滑轨沿着下箱体的高度方向设置，所述上箱体的内侧设有滑块，所述滑块与滑轨相适配。
采用上述技术方案后，本发明与背景技术相比，具有如下优点：
1、本发明通过按压按钮带动拉绳通过止推件使锁销的一端缩回容置腔，松开按钮后，锁销在止推件和第一弹簧的作用下伸出容置腔实现锁止作用，锁止装置的操作非常便捷、省力。
2、本发明的锁止座上形成有若干个第二座体，各第二座体上均设有锁销和第一弹簧，且各锁销分别由连成一体的止推件来控制伸缩，使各锁销同时实现锁止作用，保证了锁止的可靠性。
3、本发明可以根据实际需要调整上箱体的高度，以改变行李箱的大小，再通过锁止装置将下箱体和上箱体连接在一起，不仅可以分别满足使用和置放的不同要求，而且行李箱大小的调节也非常方便。

配合图1至图3所示，壳体1的前侧设有用于安装按钮41的安装口11，壳体1的后侧设有用于封闭其的壳盖12，壳体1内设有若干立柱13，壳盖12固定于立柱13上，壳体1的侧边形成有延伸部14，延伸部14上设有与壳体1内部相通的凹槽141，凹槽141上设有沿其长度方向的定位槽142。
配合图1、图4及图5所示，锁止座2上设有容置腔21，锁止座2包括第一座体22和第二座体23，第一座体22上设有安装槽221和安装孔222， 第一座体22于第二座体23的一侧设有限位槽223，第一座体22往侧边延伸形成第二座体23，第二座体23上设有容置腔21，且容置腔21与安装槽221相通。
锁止机构3包括锁销31和第一弹簧32，锁销31设置于容置腔21中，第一弹簧32设于容置腔21内，并与锁销31相抵接，锁销31包括销本体311和止顶部312，销本体311的顶部设有止推口3111，在本实施例中，止推口3111的截面形状呈三角形，销本体311往侧边延伸形成止顶部312。
配合图1至图5所示，联动机构包括按钮41、拉绳42及止推件43，按钮41设于壳体1上，拉绳42的下端与按钮41相连接、上端与止推件43相连接，通过止推件43使锁销31的一端缩回/伸出容置腔21。
按钮41的背面设有连接座411，连接座411上转动设置有铰接件44，拉绳42的下端转动地连接于铰接件44上，按钮41通过第二弹簧45进行复位。
拉绳42的上端穿过锁止座2的安装孔222后与止推件43相连接，拉绳42下端的端部设有下连接头421，下连接头421转动地连接于铰接件44上，下连接头421上设有第一挡块4211，下连接头421穿设于凹槽141中，并使第一挡块4211沿着定位槽142移动，凹槽141的长度大致与止顶部312的移动距离相适应，使得按钮41的按压一个行程能够使止顶部312缩回容置腔21。在本实施例中，拉绳42采用刚性绳，同时，为确保拉动时的稳定性和准确性，沿着拉绳42的布绳方向设置有限位块(图中未示出)，拉绳42活动地穿设于限位块中，以防止其在拉动时发生晃动或者移位。
止推件43设于安装槽221中，并抵接于销本体311的止推口3111上，止推件43下端的形状与止推口3111的形状相适应，在本实施例中，止推口3111的截面形状优选为直角三角形，使得止推件43在止推口3111中的移动更加准确。止推件43的侧边分别延伸形成有第二挡块431和连接部432，第二挡块431在限位槽223中移动，防止止推件43脱离止推口3111，连接部432上设有通孔，拉绳42活动穿设于连接部432中，并在其顶端设有上连接头422。
在本发明中，锁止座2和锁止机构3的数量至少包括两个，按钮41上连 接有多根拉绳42，各拉绳42的上端均连接有止推件43，用于实现各锁止机构3的锁止作用。优选地，在本实施例中，锁止座2和锁止机构3的数量均为两个，按钮41上连接有两根拉绳42，两根拉绳42的上端分别连接有止推件43，两根拉绳42可以同步动作分别拉动止推件43，使锁销31的一端缩回/伸出容置腔21，两个锁止机构3一起实现锁止作用，保证锁止的可靠性。
实施例二
配合图1、图6及图7所示，本实施例与实施例一的区别在于：
第一座体22往侧边延伸形成有若干个第二座体23，第一座体22上设有与第二座体23数量相对应的安装槽221，各第二座体22上均设有容置腔21，容置腔21分别与安装槽221相通，容置腔21内均设有锁销31和第一弹簧32，止推件43的数量与第一座22体的数量相对应，且各止推件43的连接部432连成一体，各止推件43分别抵接于锁销31的止推口3111上。
在本实施例中，第一座体22往侧边延伸形成的第二座体23的数量优选为两个，止推件43的数量也为两个，两止推件43的连接部432连成一体，两止推件43分别抵接于锁销31的止推口3111上。拉绳42可以同时拉动各止推件43，使各锁销31的一端缩回/伸出容置腔21，使得各锁销31一起实现锁止作用，进一步保证了锁止的可靠性。
实施例三
配合图1、图8至图12所示，本发明还公开了一种行李箱，包括下箱体200、上箱体300及上述的锁止装置100，下箱体200上设有下锁孔210，上箱体300于与下锁孔210同一平面的位置上至少设有两个上锁孔310，锁止装置100设于下箱体200的内侧壁上，且锁止装置100的锁销31伸入下锁孔210中，并插入其中一个上锁孔310中，以将下箱体200和上箱体300连接在一起。
在本实施例中，下箱体200上设有滑轨220，滑轨220沿着下箱体200的高度方向设置，上箱体300的内侧设有滑块320，滑块320与滑轨220相适配，上箱体300相对下箱体200进行移动时，通过滑块320与滑轨220相适配既 可以提高上箱体300和下箱体200之间连接的稳定性，又可以使止顶部312与上锁孔310的对位更准确。
本发明的工作原理如下：
行李箱在未调整状态时，第一弹簧32处于被压缩状态，以使锁销31往容置腔21的外侧伸出，同时，由于止推件43的第二挡块431被限位槽223限制，而使得止推件43的下端抵在止推口3111靠近顶部的位置，以限制锁销31往外伸出的长度，使锁销31的止顶部312露出容置腔21。此时，往外伸出的止顶部312伸入下箱体200的下锁孔210中，并插入上箱体300的其中一个上锁孔310中，进而将下箱体200和上箱体300连接在一起。
需要调节行李箱的高度时，先按压按钮41，使上箱体300可以相对下箱体200进行上下移动，再移动下箱体200至所需高度，并使止顶部312插入上箱体300的另一个上锁孔310中，使下箱体200和上箱体300连接在一起即可，具体过程为：
按压按钮41后，按钮41背面的连接座411随按钮41往壳盖12方向移动，使得连接座411上的铰接件44往按钮41中部转动，进而向下拉动拉绳42，止推件43在拉绳42的拉动下，由止推口3111靠近顶部的位置向下移动至其底部。此时，第一弹簧32进一步被压缩，锁销31的止顶部312由容置腔21的外侧缩回，不再插入上箱体300的上锁孔310中，上箱体300可以相对下箱体200进行上下移动，上箱体300相对下箱体200移动至所需的确定高度后，使止顶部312插入上箱体300的另一个上锁孔310中即完成行李箱大小的调节。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
