Description

一种门锁把手双向定位机构 技术领域
本实用新型涉及一种门锁把手双向定位机构， 其特别有关于在一锁面内部的结构上装配两个复位片，用弹簧将两个复位片连接，两个复位片与弹簧一起形成一个封闭结构，对装配在门锁和把手上的定位块起到限位作用，定位块与把手相连可以与把手互相驱动，从而利用弹簧的回复弹力促进把手复位功能，对把手起到定位作用。
背景技术
目前市场上的门锁种类多种多样，把手的定位结构种类也越来越多，大部分的定位结构都是选用弹簧的结构特征，例如涡簧和拉簧；其中涡簧一般为环形，利用涡簧的向心扭力的特性来实现把手定位；拉簧一般为长条形，利用拉簧的回复力，实现定位功能；为了实现把手的双向复位平衡以及定位功能，在门锁把手定位结构中拉簧的应用数量一般需要两根，把手受到不同方向外力的时候会使两根拉簧分别受拉，从而达到门锁把手双向定位的功能，如何精简零件数量，简化产品结构，成为一项新的技术研究方向。
技术问题
技术解决方案
本实用新型的目的是提供一种新型的门锁把手双向定位机构，跟之前的双向把手定位机构相比，具有精简了零件，节约成本，减小体积，装配方便，生产成本低等特点。
为了达到上述目的，本实用新型的技术方案如下：
一种 门锁把手双向定位机构 ，把手组件1、锁面2、复位组件3，其特征在于，包括：锁面2上有定位柱21、圆孔22，把手组件1上有正方形结构，把手组件1装配在锁面2的圆孔22内并可绕圆孔22旋转；复位组件3的一端装配在锁面2的定位柱21上，另一端卡装在把手组件1的正方形结构上，复位组件3受把手组件1驱动。
所述复位组件3由第一复位片31、第二复位片32、拉簧33组成，第一复位片31上有第一圆孔311，第一端点312，第二复位片32上有第二圆孔321，第二端点322，第一圆孔311和第二圆孔321依次套装在定位柱21上；拉簧33的一端装配在第一端点312上，拉簧33的另一端装配在第二端点322上； 第一复位片31和第二复位片32分别位于把手组件1的正方形结构的对边，对把手组件1形成限位结构。
所述把手组件1由把手11和定位块12组成，把手11上至少有一个卡掣块，定位块12上至少有一个凹槽，把手11上的卡掣块与定位块12上的凹槽相嵌合固定。
所述把手组件（1）上的正方形结构也可以是菱形的。

 本发明的最佳实施方式
本发明的实施方式
下面结合附图和实施例对本实用新型作进一步详细的说明：
如图1，图2所示，在锁面2内部的定位柱21上上下依次装配两个复位片:第一复位片31和第二复位片32，用拉簧33将两个复位片的另一头连接，两个复位片与拉簧33一起形成一个封闭结构，两个复位片夹紧了定位块12的正方形的两个对边从而对定位块12起到限位作用，定位块12与把手11相连且可以与把手11互相驱动，从而利用拉簧33的回复弹力促进把手11定位功能，对把手11起到定位作用。
如图2，图3所示，当把手组件1受到外力作用进行逆时针旋转动作时，把手组件1上的正方形结构对装配在两边的第一复位片31和第二复位片32产生向外侧的推动力，此时装配在两个复位片上的拉簧33受到拉力，产生形变，使两个复位片更加夹紧了把手组件1，当把手11旋转45°时，方形结构的对角与两个复位片相接触，拉簧33的形变达到最大；如图4所示，把手11继续旋转，达到90°时停止，此时方形结构的另外两个对边被两个复位片夹紧而重新被定位。
显而易见，当把手组件1受到外力做顺时针旋转时，把手组件1上的正方形结构对装配在两边的第一复位片31和第二复位片32产生向外侧的推动力，此时装配在两个复位片上的拉簧33受到拉力产生形变，使两个复位片更加夹紧了把手组件1，当把手11旋转45°时，方形结构的对角与两个复位片相接触，拉簧33的形变达到最大；如图4所示，把手11继续旋转，达到90°时停止，此时方形结构的另外两个对边被两个复位片夹紧而重新被定位。
综上，本实用新型是一种门锁把手双向定位机构，无论把手逆时针旋转还是顺时针旋转当把手旋转到位时，本机构总能将把手相对于锁面定位。
