Glass lifter capable of adjusting tightness of steel wire rope

The utility model discloses a glass lifter capable of adjusting the tightness of a steel wire rope, which is characterized in that a plurality of clamping structures are arranged on a spring core along the length direction, so that the spring core is adjustably arranged on a mounting plate; the mounting position of the spring core can be adjusted to prevent the steel wire rope from being damaged or jumping out of a groove, and meanwhile dimensional deviation of the steel wire rope caused by factors such as machining errors is compensated; in addition, the spring core and the mounting plate arelocked together through a rotary matching type locking structure, so that the spring core is prevented from being disengaged from the mounting plate. 本实用新型公开了一种可调节钢丝绳松紧度的玻璃升降器，通过在弹簧芯沿长度方向设置的若干卡紧结构，使得弹簧芯可调节地安装在安装板上，当钢丝绳安装的过紧或过松时，可以调节弹簧芯的安装位置避免钢丝绳损坏或出现跳槽的情况，同时也弥补了钢丝绳由于加工误差等因素所导致的尺寸偏差；此外，弹簧芯与安装板之间通过旋转配合式锁紧结构锁紧在一起，避免了弹簧芯从安装板上脱出。
