The invention discloses a through channel which comprises two semi-windshield assemblies, the two semi-windshield assemblies are locked through a lock assembly, and a vehicle body frame assembly of the semi-windshield assemblies is provided with a side protection plate support assembly for installing a side protection plate assembly. The side protection plate assembly comprises a middle protection plate assembly, a lap joint protection plate assembly and a side protection plate assembly; the middle protection plate assembly is provided with a middle protection plate wear-resistant layer which is in sliding fit with the lap joint protection plate assembly; the lap joint guard plate assembly is provided with a pin seat body and a lap joint guard plate mounting shaft; the pin seat body is installed on the lap joint protection plate assembly and protrudes out of the lap joint protection plate assembly. A wearing plate which is in sliding fit with the middle protection plate is arranged on the convex part; and the lap joint guard plate mounting shaft is positioned between the wearing plate on the convex part and the lap joint guard plate assembly. In the contraction or stretching process of the side protection plates, the force acting on the lap joint protection plate installation shaft cannot cause the lap joint protection plate assembly to horizontally rotate, the lap joint protection plate assembly can be prevented from colliding with other parts, and the service life of the side protection plates and the service life of the through channel are guaranteed.
本发明公开了一种贯通道,包括半风挡组成,两个半风挡组成通过锁组成锁定,半风挡组成的车体框组成上设置有安装侧护板组成的侧护板支座组成;侧护板组成包括中间护板组成、搭接护板组成和边护板组成,中间护板组成设置有与搭接护板组成滑动配合的中间护板耐磨层;搭接护板组成设置有销座本体和搭接护板安装轴;销座本体安装在搭接护板组成上并凸出搭接护板组成;凸出部上设置有与中间护板组成滑动配合的磨耗板;搭接护板安装轴位于凸出部上磨耗板与搭接护板组成之间。在侧护板收缩或拉伸过程中,作用在搭接护板安装轴上的力不会导致搭接护板组成发生水平转动,可避免搭接护板组成与其他部件发生碰撞,保证侧护板和贯通道的使用寿命。
