The invention relates to the technical field of rims, and discloses a precise pre-tightening force control structure for heavy rim locking, which comprises a rim, a spoke fixedly connected to the inner wall of the rim, a hub fixedly connected to one end of the spoke and a connecting assembly arranged on one side of the rim, and the connecting assembly comprises a control mechanism arranged on the inner side of the rim. A silencing mechanism is arranged on the outer side of the rim, the positioning strips and the positioning grooves are arranged in a clamped mode, the rectangular columns are slidably connected to the inner walls of the rectangular grooves and the outer walls of the limiting columns, the ends, away from the rotating rods, of the first springs are fixedly connected with the connecting blocks, and the clamping rods and the clamping grooves are arranged in a clamped mode. The problems that in the prior art, when a rim and a wheel shaft are locked through bolts, threads are possibly damaged due to too large pre-tightening force, looseness cannot be effectively prevented due to too small pre-tightening force, and the locking effect between the rim and the wheel shaft is affected are solved.
本发明涉及轮辋技术领域,且公开了重型轮辋锁定用预紧力精确控制结构,包括轮辋,固定连接在轮辋内壁的轮辐,固定连接在轮辐一端的轮毂,以及设置在轮辋一侧的连接组件,所述连接组件包括设置在轮辋内侧的控制机构,所述轮辋外侧设置有消音机构,所述定位条与定位槽卡接设置,所述矩形柱滑动连接在矩形槽的内壁,所述矩形柱滑动连接在限位柱的外壁,所述第一弹簧远离转杆一端与连接块固定连接,所述卡接杆与卡接槽卡接设置。本发明解决了现有技术中的轮辋与轮轴通过螺栓进行锁定时,预紧力过大可能导致螺纹损坏,预紧力过小则无法有效防止松动,从而影响了轮辋与轮轴之间的锁定效果的问题。
