Straight cylinder spring not prone to deformation

The utility model discloses a straight cylinder spring not prone to deformation, and belongs to the technical field of springs. A threaded groove is formed in the top of the bottom plate, a threaded rod is in threaded connection in the threaded groove, a limiting column is fixedly connected to one end of the threaded rod, a sliding groove is formed in one end of the limiting column, a sliding rod is slidably connected in the sliding groove of the limiting column, a top plate is fixedly connected to one end of the sliding rod, and a spring body is arranged between the bottom plate and the top plate. The spring can avoid fracture caused by deformation and bending due to excessive pressure bearing or stretching of the spring body. 本实用新型公开了一种不易变形的直筒弹簧，属于弹簧技术领域，包括：底板；所述底板顶部开设有螺纹槽且螺纹槽内螺纹连接有螺纹杆，所述螺纹杆一端固定连接有限位柱，所述限位柱一端开设有滑槽，所述限位柱的滑槽内滑动连接有滑杆，所述滑杆一端固定连接有顶板，所述底板和顶板之间设置有弹簧本体，本实用新型可避免弹簧本体承压或拉伸过度，而变形弯曲造成断裂。
