Description

一种可限制抽屉开启数量的工具箱 技术领域
本发明属于车间工具箱技术领域，特别涉及一种可限制抽屉开启数量的工具箱，特别用于机械行业。
背景技术
车间工具箱，特别是机械行业的车间工具箱，一般用于存放一些质量比较重的工具，如铁锤、扳手、工具钳等，工人在使用过程中，由于不注意或者疏忽等原因，对开启抽屉不进行回位处理，这样会存在多个抽屉同时开启的现象，由于抽屉内的工具重量一般较重，抽屉开启较多，容易造成工具箱翻到，会对工人的人身安全以及工作环境产生危害。为了避免这种情况发生，有的专利技术只能同时开启一个抽屉，这又给需要开启两个及以上抽屉的工作情况带来了不便。如何能够根据需要限制抽屉的开启数量，是车间工具箱研究发展的一个方向。

优选的，所述滑动杆的上下两端各设有球状凸起，所述隔片下端面设有与球状凸起吻合的球状凹槽。
优选的，所述凸轮与抽屉锁之间设有延长连接杆，所述延长连接杆处设有自锁定位机构，所述自锁定位装置包括在延长连接杆沿圆周方向设置的若干个凹槽，所述箱体的对应位置设有弹簧，所述弹簧的头端设有球体,所述球体与所述凹槽 相匹配,所述弹簧的外部套装限位套管，所述限位套管可限制弹簧摆动。
优选的，所述滑动杆的横截面为矩形或者多边形，所述套管与滑动杆相匹配，以防止滑动杆发生转动。

本发明的实施方式
下面结合附图，对本发明的一个具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
如图1-10所示，本发明实施例提供的一种可限制抽屉开启数量的工具箱，包括箱体1、若干个抽屉2,抽屉2通过滑轨与箱体1配合连接，每个抽屉2上都设有拨动杆3，拨动杆3固定在抽屉2后端任意一侧，在每个拨动杆3处对应设有套管4，所述套管4固定在箱体1上，所述套管4内设有一个可上下滑动的滑动杆5，相邻滑动杆5在重力的作用下，上下端接触到一起，结合图5所示, 所述滑动杆5的横截面为矩形或者多边形，所述套管4与滑动杆5相匹配，以防止滑动杆5发生转动，如滑动杆5发生转动，会影响工具箱的使用。所述滑动杆5的下端设有安装座12，隔片6通过转轴安装在安装座12上，并可相对于安装座12和滑动杆5转动；所述隔片6上设有与拨动杆3配合的拨动槽7，拨动杆3卡接在拨动槽7内，向外侧拉抽屉2，拨动杆3运动，拨动杆3带动隔片6转动，使隔片6转动到其对应两个滑动杆5之间，从而使其上方的滑动杆5向上运动。最上方滑动杆5顶端处设有凸轮8，所述凸轮8与抽屉锁9的锁芯固定连接并跟随锁芯转动，所述凸轮8为平面阶梯形凸轮，同一阶梯的失径相同即为相应的有效失径，所述凸轮的阶梯个数即有效失径数等于工具箱允许同时开启的最多抽屉数加一。凸轮8与抽屉锁9都安装在箱体1上。最下方滑动杆5可以不安装安装座12和隔片6，其底端抵靠在箱体1的底侧板上。抽屉锁8采用市面上最常见的抽屉锁，插入钥匙转动，可使锁芯转动，拔出钥匙后，锁芯不能够自由转动，通过转动抽屉锁9的锁芯，使凸轮8转动，以改变凸轮8下端最低点与最上方滑动杆5顶端之间的间隙，从而改变滑动杆5可向上的移动距离，此间隙的设置(也就是凸轮8形状的设定)与隔片6的厚度相匹配，结合图6-8所示加以说明，图6所示，当凸轮8的A点处于最低点时，A点与最上方滑动杆5顶端之间的间隙小于一个隔片6的厚度，任何一个隔片6不能够转入两滑动杆5之间，隔片6处于锁定状态，这时所有抽屉2都处于锁定状态；如图7所示，当凸轮8的B点处于最低点时,B点与最上方滑动杆5顶端之间存在一定的间隙，滑动杆5具有可向上的移动空间，此间隙只允许其中一个隔片6转入两滑动杆5之间，当其中一个隔片6转入后，滑动杆5向上移动，此时，最上方滑动杆5顶端与B点之间的间隙不足以使第二个隔片6转入两滑动杆5之间，此时，只能够同时开启一个抽屉2；如图8所示，当凸轮8的C点处于最低点时,C点与最上方滑动杆5顶端之间存在一定的间隙，滑动杆5具有可向上的移动空间，此间隙只允许其中两个隔片6同时转入两滑动杆5之间，当其中两个隔片6转入后，滑动杆5向上移动，此时，最上方滑动杆5顶端与C点之间的间隙不足以使第三个隔片6转入两滑动杆5之间，此时，最多同时开启两个抽屉2。同理依次类推，可以根据自身需要，设定同时可开启抽屉的数量。
结合图9所示,为了能使隔片6顺利转进两滑动杆5之间，所述滑动杆5的上下两端各设有球状凸起10，使隔片6与滑动杆5的接触面为弧形，更容易隔 片6插入滑动杆5之间；所述隔片6下端面设有与球状凸起10吻合的球状凹槽11，可以增加隔片6转入后整个机构的稳定性，使隔片6不轻易滑出，影响使用。
结合图10所示.所述凸轮8与抽屉锁9之间设有延长连接杆13，所述延长连接杆13处设有自锁定位机构，所述自锁定位机构的结构是：在延长连接杆13沿圆周方向设有若干个凹槽14，凹槽14的设置与凸轮8形状相对应，所述箱体1的对应位置设有弹簧15，所述弹簧15的头端设有球体16，弹簧15另一端固定在箱体1上，所述球体16与所述凹槽14相匹配,所述弹簧15的外部套装限位套管17，所述限位套管17可限制弹簧15摆动，所述限位套管的一端固定在箱体1上。每个凹槽14对应凸轮8的一个阶梯，也就是各个凹槽14位置的设定与凸轮8A点、B点、C点、D点相对应，设置此结构，既能防止抽屉抽拉过程中连接杆13转动，保证凸轮8状态的稳定，又能起到标记转动位置的作用，当球体16与任意一凹槽14配合时，说明凸轮8旋转到所需位置。
本发明的工作原理：初始状态下(如图6所示)，锁芯处于锁定状态，滑动杆5在重力作用下，在套管4的限位下，若干个滑动杆5从下到上依次连接在一起，最下方滑动杆5底端抵靠在箱体1的底侧板上，凸轮8的A点处于最低点，A点与最上方滑动杆5顶端之间的间隙小于一个隔片6的厚度，任何一个隔片6不能够转入两滑动杆5之间，隔片6处于锁定状态，由于拨动杆3卡接在隔片6的拨动槽7内，隔片6不能转动，拨动杆3也无法移动，从而使抽屉处于锁定状态。
钥匙插入抽屉锁9，转动锁芯，改变凸轮8下端与最上方滑动杆5顶端之间的距离，举例说明，当转动到位置一时(如图7所示)，凸轮8的B点处于最低点,B点与最上方滑动杆5顶端之间存在一定的间隙，滑动杆5具有可向上的移动空间，此间隙只允许其中一个隔片6转入两滑动杆5之间，当其中一个抽屉2开启时，对应的隔片6转入两个滑动杆5之间，滑动杆5向上移动，此时，最上方滑动杆5顶端与B点之间的间隙不足以使第二个隔片6转入两滑动杆5之间，因此其他抽屉2被限制打开，只能关闭一个抽屉2，才能打开另一个，即只能够同时开启一个抽屉2；再次转动凸轮8，使其转动到位置二(如图8所示)，凸轮8的C点处于最低点时,C点与最上方滑动杆5顶端之间存在一定的间隙，滑动杆5具有可向上的移动空间，此间隙只允许其中两个隔片6同时转入两滑动杆5之间，当其中两个隔片6转入后，滑动杆5向上移动，此时，最上方滑动杆5 顶端与C点之间的间隙不足以使第三个隔片6转入两滑动杆5之间，此时，最多同时开启两个抽屉。依次类推，可以根据自身需要，设定同时可开启抽屉的数量。
为使工具箱工作可靠，凸轮8的失径和拨动杆3的安装位置及长度应满足以下要求：
1.凸轮8的有效失径设计要与隔片6厚度相匹配。并满足下式要求：
h-(n-1)×b-a≥R＞h-n×b-a
式中：
a为隔片6厚度；
b为球状凹槽11底部的隔片6厚度；
n为限制开启抽屉数；
h为所有抽屉2均关闭时，凸轮8的中心与最上方滑动杆5顶端的距离；
R为限制开启抽屉数为n时，凸轮8指向滑动杆5方向的失径，即有效失径；
2.拨动杆3的安装位置及长度应满足以下要求
每个抽屉的拨动杆3的下端面不应高于所有抽屉2处于锁定时的对应隔片6的下平面。当k＜N时(N为工具箱限制开启抽屉的最大数)，从下向上数第k个抽屉的拨动杆3的上端面，不应低于第k及以下所有抽屉都开启时对应隔片6的上平面。当k≥N时，从下向上数第k个抽屉的拨动杆3的上端面，不应低于第k及以下N个抽屉都开启时，对应隔片6的上平面。
从下向上数第k个抽屉的拨动杆3的最小长度为e
当k＜N时，e＝(k-1)b+a
当k≥N时，e＝(N-1)b+a
以上公开的仅为本发明的几个具体实施例，但是，本发明实施例并非局限于此，任何本领域的技术人员能思之的变化都应落入本发明的保护范围。
工业实用性
本发明可用于各种工具箱、衣橱、衣柜等多抽屉的箱体类器具，可限制抽屉同时开启的数量，且其具体开启数量也可以根据需求进行设定，避免了抽屉开启过多，发生箱体倾倒的现象。应用面广，工业实用性强。
