Guide rail mechanism, pushing plate and compression type garbage truck

The invention provides a guide rail mechanism, a pushing plate and a compression type garbage truck, relates to the technical field of compression type garbage trucks, and solves the technical problemabout how to simply replace a friction block. The guide rail mechanism comprises a rail, a friction block and a baffle plate assembly, wherein the rail is provided with two guide walls which are oppositely arranged; upper and lower walls of the friction block separately cling to the two guide walls; and the two ends of the baffle plate assembly separately and correspondingly press the two ends ofthe friction block and the two ends of each guide wall detachably, so that the baffle plate assembly is dismounted for replacing the friction block. 本发明提供了种导轨机构、推板和压缩式垃圾车，涉及压缩式垃圾车技术领域，解决了如何简便更换摩擦块的技术问题。该导轨机构包括轨道、摩擦块和挡板组件，所述轨道具有两个相对设置的导向壁；所述摩擦块的上下壁分别紧贴两个所述导向壁；所述挡板组件的两端分别对应可拆卸的压设所述摩擦块和所述导向壁的两端，从而拆卸所述挡板组件来更换所述摩擦块。
