An automobile safety tensioning device is characterized in that a seat body is provided with a tape winding assembly linked with a main shaft, the tape winding assembly comprises a tape winding disc and a coil spring, and a stop plate and a pressing plate are arranged in front of and behind the seat body; the handle is pivoted with the seat body and can rotate around a main shaft, the driving pawl is rotatably connected to the handle, and the device is characterized in that the top of the seat body is provided with three operation sections which are matched with a limiting block on the driving pawl and are respectively a tensioning area, a working area and a releasing area, and when the limiting block on the driving pawl is limited in the working area, the tensioning area is matched with the working area, and the releasing area is matched with the working area. The driving pawl and the pressing plate are both separated from the ratchet wheel, the stop plate is meshed with the ratchet wheel, and the moment M1 generated by the stop plate on the tape winding disc is smaller than the moment M2 generated by the coil spring on the main shaft, so that the braid can be tightened through the coil spring when loosened. According to the device, the braid can be automatically wound when the braid is loosened due to jolting in a working state, so that the braid is always kept in a tensioned state, unhooking is prevented, and the use safety is greatly improved.
一种汽车安全拉紧装置,在其座体上装有与主轴连动的卷带组件,卷带组件包括卷带盘和卷簧,座体前后设有止动板和压板;手柄与座体枢接可绕主轴转动,主动棘爪呈可转动地连接在手柄上,其特征是在座体的顶部设有三个与主动棘爪上的限位块相配合的操作区段,分别为拉紧区、工作区和释放区,其中当主动棘爪上的限位块限位于工作区时,主动棘爪与压板均与棘轮处脱离状态,而止动板与棘轮处啮合状态,且止动板在卷带盘上产生的力矩M1小于卷簧在主轴上产生的力矩M2,使织带在松弛下能通过卷簧收紧。本发明能在工作状态颠簸导致织带松弛时自动卷收织带,使织带始终保持张紧状态,防止脱钩,大大提高使用安全性。
