The invention relates to a contact type double-section rigidity limiting stopper which comprises an upper mounting plate, a shell, a pressing plate, a pulling plate, a middle connecting body, a bottom plate, a low-rigidity elastic body, a high-rigidity elastic body and a transverse elastic body, the pressing plate is arranged in the shell, the middle connecting body and the pulling plate are arranged in the middle, the high-rigidity elastic body is arranged between the pressing plate and the pulling plate and fixedly connected with the pulling plate, and the transverse elastic body is fixedly connected with the bottom plate. A low-rigidity elastomer is arranged between the high-rigidity elastomer and the middle connector, a transverse elastomer is arranged between the pull plate and the inner wall of the shell, the upper end of the middle connector is fixedly connected with an upper mounting plate, and the lower end of the shell is fixedly connected with a bottom plate. The limiting stopper is of a contact type structure and is convenient to install, and the problem that the contact type limiting stopper needs to accurately control the limiting gap does not exist; the low-rigidity elastic body can guarantee low rigidity in the vertical direction and the transverse direction, the high-rigidity elastic body is adjustable in shape and material hardness, and the requirement for the limiting rigidity of the ship cabin raft in the inclining, swinging and impacting states can be met.
本发明涉及一种接触式双段刚度限位器,包括上安装板、壳体、压板、拉板、中间连接体、底板、低刚度弹性体、高刚度弹性体、横向弹性体,壳体内设有压板、中间设有中间连接体,拉板,压板与拉板之间装有高刚度弹性体,高刚度弹性体与拉板固定连接,高刚度弹性体与中间连接体之间设有低刚度弹性体,拉板与壳体内壁之间设有横向弹性体,中间连接体上端固定连接上安装板,壳体下端固定连接底板。本发明的限位器为接触式结构,安装方便,不存在接触式限位器要求精确控制限位间隙的问题;低刚度弹性体可保证垂向和横向均具有较低刚度,高刚度弹性体形状可调,材料硬度可调,可保证船舶舱筏在倾斜、摇摆和冲击状态下对限位刚度的需求。
