The invention relates to a reel assembly, which can be arranged in a braid retractor or a wheelchair fixer of a safety belt system, is used for bearing a load for tensioning a braid, and comprises a shaft rod, a shaft tube coaxially sleeved on the outer side of the shaft rod, and two ratchet wheels respectively and fixedly arranged at two axial ends of the shaft rod combined with the shaft tube, the wheel plate parts of the two ratchet-gear wheels are respectively provided with a reinforcing support structure between the shaft rod and the shaft tube, and the reinforcing support structures deviate relative to the inner plate surfaces of the wheel plate parts, extend along the inner plate surfaces and pass through a reference plane vertical to the shaft rod; the reinforced support structure can reinforce the fixed connection part between the end part of the shaft tube and the ratchet wheel, when the shaft tube bears the load when the braid is tensioned, the load can be effectively distributed on the cross section with a larger area, and the stress borne by the fixed connection part between the ratchet wheel and the shaft tube in unit area is reduced, so that the service life of the braid is prolonged, and the service life of the braid is prolonged. The mechanical strength of the reel assembly is improved, so that the reel assembly can bear higher load.
本发明涉及一种卷轴组件,其能设置于安全带系统的织带卷收器或轮椅固定器中,用以承载织带张紧的负载,卷轴组件包括轴杆、同轴套设于轴杆外侧的轴管,以及分别固设于轴杆与轴管结合的轴向两端的二棘齿轮,该二棘齿轮的轮板部于轴杆与轴管之间各设一强化支撑构造,且强化支撑构造相对于轮板部的内板面偏位,沿着内板面延伸且垂直于轴杆的参考平面通过强化支撑构造,使强化支撑构造能对轴管的端部与棘齿轮之间的固接部位产生补强作用,在轴管承受织带张紧时的负载时,能有效地将负载分布在更大面积的横截面上,降低棘齿轮与轴管之间的固接部位单位面积承受的应力,借此,提高卷轴组件的机械强度而能承受更高的负载。
