Description

复合锯斜切式防护罩 技术领域
本实用新型涉及复合锯技术领域，尤其是涉及一种复合锯斜切式防护罩。
背景技术
现有的复合锯，在斜切式锯片上是有安装防护罩的。该防护罩的不足之处在于它在工作时，抬起框架时防护罩出来包住锯片，进行安全保护，把框架压下来，对工作进行切割时，防护罩升起露出锯片进行工作。其不合理的就是在由斜切式改为台切式工作时。框架是压下来的，那斜切式防护罩是收起状态。也就是说在台切式工作时，下面的斜切式工作面上的锯片上露出在面板组件的下表面，锯片容易误伤使用者。还有就是合理性，它是机动性的防护，也就是说在没有工件时，只要压下框架，该防护罩就会升起露出锯片，安全性能不高，因此有必要予以改进。
实用新型内容
针对现有技术存在的不足，本实用新型的目的是提供一种新的复合锯斜切式防护罩，其结构简单，成本低，在任何状态下以及改成台切式工作时，锯片的下半部都不会暴露在外，还有就是斜切式防护罩是随着工件的进入才起作用的，斜切式防护罩是随动性的，斜切式防护罩动作更加可靠，复合锯在使用时更加安全，增加复合锯的安全性。
为了实现上述目的，本实用新型所采用的技术方案是：复合锯斜切式防护罩，它包括有前防护罩、辅助防护罩和后防护罩，前防护罩和后防护罩的外端分别设置用于连接框架的连接部，辅助防护罩的前端连接前防护罩，辅助防护罩的后端连接后防护罩。
所述辅助防护罩包括左防护罩片和右防护罩片，左防护罩片和右防护罩片拼接成辅助防护罩。
所述左防护罩片的后端铰接于后防护罩的前端，左防护罩片的前端设置导向槽，前防护罩的后端设置导向柱，导向柱插设在导向槽中。
所述左防护罩片的后端开设有辅助限位槽，后防护罩的前端设置有辅助限位柱，辅助限位柱插设在辅助限位槽中。
采用上述结构后，本实用新型和现有技术相比所具有的优点是：其结构简单，成本低，在任何状态下以及改成台切式工作时，锯片的下半部都不会暴露在外，还有就是斜切式防护罩是随着工件的进入才起作用的，斜切式防护罩是随动性的，斜切式防护罩动作更加可靠，复合锯在使用时更加安全，增加复合锯的安全性，本实用新型的斜切式防护罩亦可以使用于普通的斜切割机和拉杆式斜切割机上。
