Description

一种弹簧机械锁 技术领域
本发明涉及锁具技术领域，具体来说是一种弹簧机械锁。
背景技术
现有技术中电池盒的锁具一般有机械锁和弹簧锁两种形式，机械锁是通过锁芯转动带动锁舌伸缩，来控制锁闭，其优势在于结构简单、稳定、牢固，防盗性能好，但是机械锁在电池盒的应用中主要问题在于使用不方便，安装电池盒时需要双手操作，一手控制钥匙打开机械锁，另一手操作电池盒置于预设安装位置，再将机械锁锁闭。弹簧锁通过锁芯转动带动锁舌伸缩，同时锁舌在外力作用下也能进行收缩，并通过弹簧力复位，弹簧锁的优势在于操作方便，安装电池盒时只需单手操作，电池盒压住锁舌，锁舌在外力的作用下收缩，电池盒达到预设安装位置时，弹簧带动锁舌复位，将电池盒锁闭，但是弹簧锁也存在以下问题：1、防盗性能不好，弹簧锁锁舌在外力作用下易克服弹簧弹力缩回；2、锁闭性不好，电动车在行驶中会产生震动，震动会导致电池盒脱离锁舌。
中国专利201220010030.7公开了一种弹簧机械锁，锁舌的上端设置有卡簧，压杆的中端设置有可抵住腔体顶端内壁的上卡环，腔体的下端内壁设置有套住锁舌的下卡环，卡簧与上卡环之间设置有上弹簧，卡簧与下卡环之间设置有下弹簧，上弹簧和下弹簧的两端分别设置有垫片，下弹簧的劲度系数大于上弹簧的劲度系数。该专利通过上弹簧和下弹簧来控制启闭，该专利只是解决了机械锁的控制问题，并不能同时具备机械锁和弹簧锁的优势。
发明内容
本发明的目的在于解决弹簧锁不够安全，机械锁操作不便的问题，提供一种能够结合弹簧锁与机械锁优点的弹簧机械锁。
为了实现上述目的，设计一种弹簧机械锁，包括锁壳(1)、锁芯(2)、锁舌(3)和弹簧(5)，锁壳(1)内设有L形腔体，锁芯(2)和锁舌(3)在腔体内配合，弹簧(5)一端连接锁壳腔体内壁，弹簧(5)另一端连接锁舌(3)，其特征在于所述锁舌(3)下部开设有一凹槽，凹槽一侧设有一缺口形成的台阶结构，所述锁芯(2)顶部设有凸块与锁舌(3)配合：0位时，锁芯(2)顶部凸块设置于锁舌(3)凹槽内，凸块对锁舌(3)没有限位，锁舌(3)在外力和弹簧复位力作用下进行伸缩；基于0位，正向旋转锁芯，锁芯(2)顶部凸块抵住锁舌(3)凹槽一侧的台阶结构，带动锁舌(3)向内位移，压缩弹簧，反之，在弹簧复位力的作用下，带动锁舌(3)向外位移，此时为弹簧锁；基于0位，反向旋转锁芯，锁芯(2)顶部凸块从锁舌(3)凹槽另一侧旋转至锁舌(3)后部一端，对锁舌(3)进行限位，此时切换为机械锁，锁舌(3)在外力作用下，不可伸缩。
优选地，锁芯上设有一槽口，弹簧滚珠紧钉螺丝安装在锁壳上，用于和锁芯上的槽口相配合。
优选地，锁芯基于0位正向旋转90°时，锁舌缩回行程达到最大值，弹簧滚珠紧钉螺丝弹出与锁芯上槽口配合，用于锁舌在弹簧锁状态的定位力。
优选地，锁壳上还设有锁舌定位螺丝和锁芯定位螺丝。
优选地，锁芯通过锁套安装在锁壳内。
优选地，所述锁芯(2)顶部的凸块为弧形凸块。
优选地，正向旋转可以是顺时针旋转也可以是逆时针旋转，反向旋转与正向旋转相反，可以是逆时针旋转也可以是顺时针旋转。
本发明同现有技术相比，其优点在于：将机械锁的安全和弹簧锁的方便相结合，正常使用时，与弹簧锁一样，在受外力作用时，可以伸缩，当需要防盗时，物件安装好后，需要将钥匙逆时针旋转180度，然后拔出钥匙，即可开启防盗功能。

具体实施方式
下面结合附图对本发明作进一步说明，本发明的结构和原理对本专业的人来说是非常清楚的。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一，参见图1和图2，本发明为一种弹簧机械锁，具体结构如下：
包括锁壳、锁芯、锁舌和弹簧，锁壳内设有L形腔体，锁芯和锁舌在腔体内配合，弹簧一端连接锁壳腔体内壁，弹簧另一端连接锁舌，锁舌下部开设有一凹槽，凹槽一侧设有一缺口形成的台阶结构，锁芯顶部设有弧形凸块与锁舌配合。锁芯通过锁套安装在锁壳内，锁芯上还设有一槽口，弹簧滚珠紧钉螺丝安装在锁壳上，用于和锁芯上的槽口相配合。锁壳上还设有锁舌定位螺丝和锁芯定位螺丝。
实施例二，参见图3，为本发明所述的弹簧机械锁在初始位置的装配示意图，初始位置称为0位，在0位时，锁芯顶部弧形凸块设置于锁舌凹槽内，弧形凸块对锁舌没有限位，钥匙可以拔出。此时的锁与普通弹簧锁一样，锁舌在外力作用下，可以缩回，当外力不在的时候，由于受到弹簧的作用力，锁舌会自动弹回，达到锁住的目的。但是此种状态并不防盗。
实施例三，参见图4和图5，本发明所述的弹簧机械锁在0位顺时针旋转90°，此状态时为弹簧锁，钥匙不可以拔出。锁芯在旋转过程中会带动锁舌缩回，此时锁舌缩回行程达到最大值，弹簧滚珠紧钉螺丝弹出与锁芯对应位置上的凹槽配合，锁舌会固定在90°的这个位置，不用手一直扭着钥匙，方便使用，在此状态下逆时针轻轻扭动，便可回弹，很灵活
实施例四，参见图6和图7，本发明所述的弹簧机械锁在0位逆时针旋转 180°，此时为机械锁状态，此时，锁芯顶部弧形凸块从锁舌凹槽另一侧旋转至锁舌后部一端，对锁舌进行限位，此状态时，钥匙可以拔出。在此运动过程中，由于锁芯与锁舌并不接触，会很顺畅地扭动到180°位置，到此位置锁芯会与锁舌接触，锁舌在锁舌定位螺丝的作用下，并不会向外运动，同样的逆时针旋转到180°时，弹簧滚珠紧钉螺丝弹出与锁芯对应位置上的凹槽配合，会发出声响，同时手上会有一个震动感，所以逆时针旋转到180度，就到达了极限值，此时弹簧锁切换成机械锁功能，锁舌不可缩回，达到防盗的目的。
