The invention discloses a rubber anti-slip well lid which comprises a well frame, a well lid body, a groove, anti-slip rubber, a plurality of stainless steel helical teeth, a fixing rod and a pin fixedly connected to the fixing rod. According to the well lid, when the well lid body is installed on the well frame, the soft rubber part of the anti-slip rubber is compressed, the sealing performance is achieved, and sound can be prevented from being generated; the hard rubber part of the anti-slip rubber plays a role in fixing, meanwhile, a certain number of stainless steel helical teeth subjected to special treatment are embedded and fixed in the hard rubber, and the helical tooth direction of the stainless steel helical teeth just corresponds to a circle of small holes in the bottom of the well lid, so that the assembly force does not need to be increased; when the manhole cover is loosened, friction force can be generated to enable the front section of the rubber ring to deform and extrude outwards, and the helical teeth of the stainless steel helical teeth tilt inwards, so that the steel teeth clench holes to resist axial tension, loosening is prevented, a good effect is achieved, and the sound of'failing 'of the manhole cover can be completely eradicated.
本发明公开了一种橡胶防滑脱的井盖，包括井框、井盖、凹槽、防滑脱橡胶、多个不锈钢斜齿、固定杆和固定连接在固定杆上的销子。本发明中，在井框上安装井盖时，防滑脱橡胶的软胶部分被压缩，具有密封性能并能防止声响的产生；防滑脱橡胶的硬胶部分起固定作用，同时因为有一定数量的经过特殊处理的不锈钢斜齿被埋入固定在硬胶内，由于不锈钢斜齿的斜齿方向正好与井盖底部一圈的小孔洞相对应，所以不需增加装配力，当车辆从井盖上轧过去时，其可以产生摩擦力使胶圈前段部位变形向外挤压，不锈钢斜齿的斜齿往里翘起，致使钢齿咬紧孔洞来抗拒轴向张力，从而防止脱松动起到了良好的作用并能杜绝井盖发出“哐当”的声音。
