The invention discloses a self-locking type sewer well lid. The self-locking type sewer well lid comprises a mounting ring and a cover plate, the mounting ring is fixedly mounted at an opening of a sewer, the cover plate is arranged in the mounting ring, one side of the cover plate is rotatably connected with the inner wall of the mounting ring, a plurality of inserting grooves are formed in the side wall of the cover plate, locking blocks are horizontally arranged in the inserting grooves in a sealing and sliding mode, a mounting groove is further formed in the upper surface of the cover plate, a movable block is vertically arranged in the mounting groove in a sealing and sliding mode, a top-bottom-through air inlet hole is formed in the movable block, the upper end partially stretches out of the mounting groove, the lower end of the movable block is connected with the bottom wall of the mounting groove through a supporting spring, a connecting opening communicating with the insertinggrooves and the mounting groove is further formed in the cover plate, a one-way valve is arranged in the connecting opening, and the one-way valve leads to the inserting grooves through the mountinggroove. According to the self-locking type sewer well lid, when the locking blocks on the peripheral side of the cover plate abut against the inner wall of the mounting ring, the cover plate cannot shake in the mounting ring, and therefore complete fixing is achieved.
本发明公开了一种自锁紧式下水道井盖，包括：安装环，所述安装环固定安装于下水道的道口处；盖板，所述盖板设于安装环内，且一侧与安装环内壁转动连接；其中，所述盖板侧壁上开设有多个插槽，所述插槽内水平密封滑动配置有锁紧块，所述盖板上表面还开设有安装槽，所述安装槽内垂直密封滑动配置有活动块，所述活动块开设有上下贯通的进气孔，且上端部分伸出安装槽，所述活动块下端通过支撑弹簧与安装槽底壁连接，所述盖板内部还开设有连通插槽与安装槽的连接口，所述连接口内配置有单向阀，所述单向阀由安装槽通向插。本发明中，当盖板周侧的锁紧块均抵住安装环内壁时，盖板将不能在安装环内晃动，实现了完全固定。
