Protective spring-assisted nodular cast iron well lid
The invention belongs to the technical field of nodular cast iron well lids, and particularly relates to a protective spring-assisted nodular cast iron well lid. The manhole cover is reasonable in structural design and is mainly composed of the manhole cover body, the manhole cover base and the spring boosting assembly, on one hand, the groove-shaped locking plate is additionally arranged on the inner side of the manhole cover body, a locking structure composed of the protruding blocks, the radial sliding grooves, the radial rotating grooves, the movable grooves, the sliding blocks, the threaded rods and the locking blocks is additionally arranged on the manhole cover base, and the position of the groove-shaped locking plate can be locked through the locking structure; the anti-theft effect is good, and abnormal sound cannot be generated when the well lid is used; and on the other hand, the spring boosting assembly is additionally arranged between the well lid body and the well lid base, and when the locking structure unlocks the position of the groove-shaped locking plate, the well lid body can automatically pop up under the action of the spring boosting assembly, and opening is convenient.
本发明属于球墨铸铁井盖技术领域，具体涉及一种防护型弹簧助力式球墨铸铁井盖。本发明结构设计合理，其主要由井盖、井盖座和弹簧助力组件构成，一方面通过在井盖内侧增设槽型锁板，在井盖座上增设由凸块、径向滑槽、径向转槽、活动槽、滑块、螺杆和锁块构成的锁定结构，能够利用锁定结构将槽型锁板的位置锁定，防盗效果较好，井盖使用时不会出现异响；另一方面在井盖和井盖座之间增设弹簧助力组件，当锁定结构解除对槽型锁板的位置锁定时，井盖在弹簧助力组件的作用下会自动弹出，便于打开。
