上述的结构还可以替换为在螺钉 （4) 外壁上设置有轴向的卡槽 （7); 止转部件包括止转本体 （5) 以及设置于本体上的凸起 （8) 和安装块 （9); 凸起 （8) 与卡槽 （7) 适配并能够卡在卡槽 （7) 中。
同理， 也可以用在螺钉 （4) 外壁上设置有轴向的凸起的方式， 即止转 部件包括止转本体 （5) 以及设置于本体上的凹槽； 凹槽与凸起卡接。
太^"昍的 I卜鲑 ¾¾罟 π 钚 、ι诵付谇接 ( ^ o ^名小谇接 一 起， 形成一体， 其数目与所需要紧固的药筒 （1 ) 的个数对应， 根据实际应 用环境调整。
一种气溶胶灭火装置使用了上述的止转锁紧装置。
本发明的止转锁紧装置及气溶胶灭火装置， 其主要具有以下优点：
1、 本发明通过止转部件的凸起或凹槽与螺钉的卡槽或凸起的卡合， 从 而通过止转部件卡紧螺钉使得螺母能够拧紧， 解决了锁紧螺钉时其随着螺 母转动的问题， 应用在气溶胶灭火装置上其降低了气溶胶灭火装置的装配 难度， 提高了生产效率， 而且锁紧效果好， 不会发生松动。
2、 本发明的螺钉颈部设置卡环， 能够限制螺钉沿其轴向的自由度， 便 于实现止转部件与螺钉的装配以及螺母的紧固。
3、 本发明的止转锁紧装置可以通过连接环将多个连接在一起， 合为一 体， 加强其整体的结构强度， 而且止转效果更好。
附图说明

图 2为本发明的螺钉结构示意图；
图 3为本发明的止转部件的结构示意图；
图 4为灭火装置的壳体底部结构示意图。
图中： 1-药筒， 2-壳体底部， 3-止转锁紧装置， 4-螺钉， 5-止转本体， 6-螺母， 7-卡槽， 8-凸起， 9-安装块， 10-连接环。
具体实施方式
本发明提供了一种止转锁紧装置 3， 现结合附图对其进行进一步的说 明：
参见图 1， 该止转锁紧装置 3主要由依次设置的螺钉 4、 止转部件以及 螺母 6组成， 其中止转部件能够阻止螺钉 4转动且与螺钉 4卡接； 螺母 6 设置在螺钉 4的末端锁紧螺钉 4;止转装置主要包括止转本体 5以及设置在 止转本体 5上的凸起 8和安装块 9; 安装块 9主要是用来固定止转本体 5。 当螺钉 4上设置有径向的卡槽 7时， 该凸起 8设置在止转本体 5的中心径 向位置正好可以卡在卡槽 7中， 使得螺钉 4穿过止转本体 5; 当螺钉 4上设 置轴向的卡槽 7时， 该凸起 8设置在止转本体 5的外侧壁， 正好卡在卡槽 7 中， 也可以实现阻止螺钉 4转动的目的。 同理， 也可以将螺钉 4的卡槽替 换成凸起， 而在止转本体 5的对应位置设置卡槽， 即在螺钉 4外壁上设置 有轴向的凸起； 止转部件的止转本体 5上设置凹槽， 使得凸起正好可以卡 在凹槽中， 且凸起穿过止转本体 5， 在末端拧上螺母 6锁紧； 或者还可以是 在螺钉 4上设置径向凸起， 而在止转部件的止转本体 5上设置与之适配的 径向通槽， 使得凸起正好卡在通槽中， 螺母 6安装在螺钉 4的末端， 从而 锁紧螺钉 4。
一种应用上述的止转锁紧装置的气溶胶灭火装置， 参见图 2、 图 3以及 图 4， 当止转锁紧装置 3应用在气溶胶灭火装置中， 其可以用来锁紧气溶胶 灭火装置的药筒 1， 可以将螺钉 4与药筒 1的底部固连， 可以采用焊接的方 式固定在药筒 1底部也可以由内向外穿过药筒 1底部固定， 而且在其径向 开设卡槽 7以便于与凸起 8卡合； 在本发明的壳体底部 2开设有与螺钉 4 对应的螺孔而该螺孔的形状与止转本体 5的安装块 9结构相适配， 通过安 装块 9可以使得止转本体 5正好能够嵌入壳体底部 2的螺孔中并且不会发 生转动即可， 也可以不设置安装块 9， 直接将止转本体 5与壳体底部固连为 一体结构， 或者还可以将凸起 8同时与壳体底部和螺钉 4卡接即可实现止 转本体 5的定位。 本发明的凸起 8设置在止转本体 5上且可嵌入螺钉 4的 卡槽 7中， 而螺钉 4穿过止转本体 5， 延伸至壳体底部 2的螺孔外部， 拧上 螺母 6即可完成装配，当拧紧螺母 6时由壳体底部 2的螺孔卡住止转本体 5， 限制其转动， 而嵌入螺钉 4的卡槽 7中的凸起 8由止转本体 5限制， 也不 会发生转动即能够限制螺钉 4发生转动， 拧紧螺母 6， 就完成药筒 1与壳体 的固定。 当螺钉 4穿过药筒 1底部的孔延伸至药筒 1外时， 可以在药筒 1 外的螺钉 4颈部设置一个卡环， 使得其能够卡紧螺钉 4， 限制螺钉 4的轴向 自由度。
本发明的止转锁紧装置 3在气溶胶灭火装置中应用时， 当遇到组合固 定式的灭火装置时， 其在壳体内会设置有多个药筒 1， 则可以通过连接环 10将多个止转锁紧装置 3连接在一起， 形成一体， 也能够加强其整体的结 构强度， 其数目与药筒 1的数目相对应也可以根据实际使用情况调整。
上述的止转锁紧装置 3可以采用具有一定的结构强度和抵抗应力的塑 料材质或者橡胶材料。
本发明的止转锁紧装置 3不仅仅应用在气溶胶灭火装置的药筒 1固定， 也可以应用在其他的需要螺钉 4锁附但又无法实现螺母 6紧固的场合。
