Description

一种锁具
技术领域
本实用新型涉及一种锁具，特别是涉及一种具有弹性压簧的锁具。
背景技术
如已公开的日本的特开2001-139031号专利《ASSEMBLY TYPE BOXPALLET》，如图1A所示，目前有的托盘箱的侧框2、3与端框4、5之间是通过锁具7来锁紧固定，构成箱体。如图1B、1C所示，该锁具7通过锁架6安装在侧框2上，锁销15通过安装孔安装在锁架6上，并通过带有小磕碰12的挡板装置9来实现对锁销15上的手柄的夹紧限位，从而实现锁具的锁止和开启。如图1D所示，锁销15穿过该侧框边立柱2a、端框边立柱4a上的通孔10、11后旋转，使其末端的锁钩15a卡位于该端框边立柱4a，从而锁紧该侧框2与端框4。而如图1E，示出了端框边立柱4a上通孔11的另外一种结构，其锁止方法同上所述。但是，上述结构中，起锁止限位作用的小磕碰12的加工与突起的控制在制造中比较麻烦，加工成本比较高。而且，针对表面粉体涂装或喷漆处理的要求，在使用中会出现易磨损脱落影响外观的问题。

具体实施方式
如图2A～图2C所示，本实用新型的托盘箱包括底架10、侧框20和端框30。端框30通过角立柱12组配安装，而侧框20由上、下两部分21、22通过铰链24连接而成，并通过侧框组装装置18与底架10连接，在侧框两端通过锁具25与端框30锁紧固定，从而实现托盘箱的组立装配。
如图3所示，示出了本实用新型的锁具装配在侧框20上的结构，其主要包括锁销251、手柄252、锁座253、限位盖板254和弹性压簧255。锁销251的锁止端具有一锁钩部2511，用于提高锁止可靠性，手柄252连接在该锁销251另一端，其可为U形结构。该锁座253固定在侧框20两端，其两侧板上具有相对设置的锁销安装孔，锁销251贯穿其中，通过手柄252带动锁销251在锁销安装孔间移动实现锁紧和开启。限位盖板253的两侧板与锁座252的两侧板之间形成锁止空间257和开启空间258，当手柄252通过弹性压簧255夹紧于锁止空间257内时，锁销251锁止于端框30上，侧框20与端框30可锁紧固定；而当手柄252夹紧于开启空间258内时，锁销251脱离该端框30，侧框20可与端框30分离拆卸。该弹性压簧255通过限位盖板254上的压簧安装孔弹性安装在限位盖板254内。
如图4所示，示出了本实用新型端框30的结构，在其端框边立柱32的上端位置，对应该锁销251的位置，设置有长孔321。结合图3，锁止时，锁销251在抬起状态下沿A1方向移动的同时旋转一定角度至其锁钩部2511顺利通过长孔321，然后再沿A2所示方向向下按压手柄252进入锁止空间257，此时锁钩部2511卡住该端框边立柱32，锁销251不能顺利通过长孔321，实现锁具的安全锁止。反之，开启时候则需先按B2所示方向向上抬起手柄，将手柄252自锁止空间257中拉出，并在向上旋转一定角度，使锁销251的锁钩部2511与长孔321孔位重合时，沿图示B1方向移动锁销251使其顺利从长孔321中退出，然后可以按压手柄252进入开启空间258，从而将锁销251固定，此时即可进行侧框20的拆卸。在端框边立柱32的下端，具有一圆孔322，当端框30通过角立柱12组立后，利用一螺栓或销轴等连接件连接端框30与角立柱12，从而实现端框30与底架10的装配。
如图5A所示，示出了本实用新型的锁具的具体结构。由图中可以看出，该弹性压簧255通过压簧安装孔弹性安装于该限位盖板254内的压簧安装空间2543，并有部分从该压簧安装孔2541中露出该限位盖板254两侧板的外表面，形成第一卡位部2551和第二卡位部2552，起到卡紧手柄252的作用。在外力作用(手柄252下压)下压簧第一卡位部2551或第二卡位部2552受压缩发生弹性形变，第一卡位部2551或第二卡位部2552向限位盖板254内回缩，使得手柄252顺利卡入锁止空间257或开启空间258内，此时该压簧255在弹性反作用力作用下又弹出压簧安装孔2541，顶在手柄252上，从而卡紧手柄252。
如图5B、5C所示，示出了锁座253、限位盖板254的结构。锁座253由锁座底板2531两端弯折形成两个锁座侧板2532，锁座侧板2532上相对设置有该锁销安装孔2533。限位盖板254由限位底板2541两端弯折形成两个限位侧板2542，该限位侧板2542上相对设置有该压簧安装孔2543，其可为长孔(椭圆孔、适配的圆孔或其它形式的任意安装孔)，为压簧255卡入和弹出限位盖板254提供空间。
如图5D～5F所示，示出了本实用新型的压簧255的结构。压簧255使用形式可以根据锁具的实际锁紧需求在限位盖板254内使用1个或者2个，甚至多个，相应的，压簧安装孔2543的数量也随着压簧4的使用数量变化而变化。在本实用新型中，压簧255主体部分由弹性杆2550构成，该弹性杆2550的两末端进一步向外延伸形成第一卡位部2551和第二卡位部2552，而该第一卡位部2551和第二卡位部2552的末端2553进一步弯折，使得第一卡位部2551、第二卡位部2552所处平面垂直于该弹性杆2550所处平面，从而使得第一、第二卡位部2551、2252具有压缩状态下的向外张力。较佳的，该弹性杆2550呈锐角状，当然，也可为其他形状，如直角、钝角等形状，并不作为对本实用新型的限制。
如图6A、6B所示，示出了本实用新型的锁具锁止状态下的结构。当锁具锁紧时，向下按压手柄252，手柄252运动到位，锁钩部2511锁紧端框时压簧255受压缩，卡入限位盖板254内，在手柄252进入到锁止空间内后，由于压簧255的反作用力，使得其卡位部向外回弹夹紧该手柄252，如图6B所示，从而实现可靠锁紧和装配。反之则锁具开启。
当然，本实用新型还可有其他多种实施例，在不背离本实用新型精神及其实质的情况下，熟悉本领域的技术人员当可根据本实用新型作出各种相应的改变和变形，但这些相应的改变和变形都应属于本实用新型所附的权利要求的保护范围。
