Abstract

一种无挡片角码，包括卡销装置，所述卡销装置包括卡销安装槽、卡销和弹簧，所述卡销伸入卡销安装槽的一端设有挡棍，所述挡棍贯穿卡销；所述卡销安装槽一端封闭，另一端设有限位部，所述限位部中间位置开有与卡销及挡棍相配合的通孔，限位部内侧设有与挡棍相配合的限位槽。将卡销安装通孔变为卡销安装槽，使得原本应由挡片承担的功能变为由角码一体生产，不会产生因挡片而带来的一系列问题。另外，由于无挡片的结构，因此卡销及弹簧的安装改为了下部安装，无须任何机械，手工即可完成。

Description

一种无挡片角码
技术领域
本发明涉及一种角码，特别是一种无挡片角码。
背景技术
在现有技术中，角码的卡销件均安装在卡销安装孔内，其组装顺序是：放入卡销、压入弹簧、放入挡片、压实卡入挡片。但在实际应用中发现，由于弹簧对于卡销及挡片有同样的作用力，因此会导致在安装过程中挡片无法放置稳妥，稍有偏斜就会导致废件的产生；而且，由于压实卡入挡片采用的外扣紧的方式，因此事实上并不稳妥，在使用时也经常发生挡片弹出或松开的情形。
发明内容
本发明旨在提供一种无须挡片的角码，进一步的说，即一种无须挡片的卡销结构，使得组装更加方便，无须器械手动即可完成。
具体方案如下：
一种无挡片角码，包括卡销装置，所述卡销装置包括卡销安装槽、卡销和弹簧，所述卡销伸入卡销安装槽的一端设有挡棍，所述挡棍贯穿卡销；所述卡销安装槽一端封闭，另一端设有限位部，所述限位部中间位置开有与卡销及挡棍相配合的通孔，限位部内侧设有与挡棍相配合的限位槽。
作为上述方案的进一步改进，所述限位部上的限位槽与挡棍进入的通孔相互垂直。
作为上述方案的进一步改进，所述卡销为圆柱状。
本技术方案的有益效果为：将卡销安装通孔变为卡销安装槽，使得原本应由挡片承担的功能变为由角码一体生产，不会产生因挡片而带来的一系列问题。另外， 由于无挡片的结构，因此卡销及弹簧的安装改为了下部安装，无须任何机械，手工即可完成。
说明书附图
图1为本发明所述卡销安装槽限位部的内侧结构图。
图2为本发明所述卡销的结构示意图。
具体实施方式
下面结合说明书附图对本发明做进一步的说明。
如图1所示，卡销安装槽设有限位部1，限位部1的中心位置为供卡销进入的通孔101，还包括用于卡入卡销挡棍且垂直于挡棍进入通孔的限位槽102。
如图2所示，挡棍201贯穿圆柱状的卡销2。
在安装卡销结构时，将弹簧卡入卡销2的一端，然后将带有弹簧的卡销2通过限位部1上的通孔101深入到卡销安装槽内，这时弹簧收紧；然后旋转卡销2，使得挡棍201卡入限位槽102中，使得卡销不可转动。
在使用角码时，由于限位槽102与通孔101中供挡棍进入的部分相垂直，因此即便卡销收缩也不易弹出。
进一步地，还可以将限位槽102的两端位置扩大至通孔101供挡棍进入部分的边缘，这样就最大程度的保证了卡销转动的空间。
另外，卡销还可以做成其他形状，如方形、楔形等。
