The utility model provides a self closing buffering component for drawer guide rail, which comprises a closed box, self closing, touch self closing buffer cylinder, the rotating shaft component, a tension spring, which also comprises a rotary pin, wheel, rotating pin fixed on the closed box, and is located near the self closed box at the end of the match; runner with a rotating pin installed in the closed box; one end of the tension spring is fixed on the buffer cylinder fixing groove connecting piece by the fixed slot, the other end of the tension spring around the wheel and the self closing connecting groove in the shaft is connected with an annular groove and the surrounding, a tension spring and a runner self closing and touch; buffer cylinder force point in the same line. After adopting the proposal, the utility model can greatly reduce the pulling force needed to pull the drawer, and can make the force of the self closing buffer component even, thereby increasing the service life of the self closing buffer assembly.
【技术实现步骤摘要】
本技术涉及抽屉导轨
,尤其是指用于抽屉导轨的自关缓冲组件。
技术介绍
在橱柜、办公桌、家用电器等产品内大多设置有抽屉或类似抽屉的部件,为了方便 这些抽屉的开关,通常在抽屉的两侧及对应的固定壁之间安装有抽屉导轨,而自关及缓冲 组件是高档抽屉导轨内不可或缺的部件,其作用是将抽屉关闭到一定距离时,抽屉能自动 地、缓慢地关闭,且防止关闭的抽屉自动打开。通常的自关组件与缓冲组件独立作用,其中 自关组件由自关盒、弹簧、自关碰件、自关驱动件等来实现自关功能,而一旦出现异常关闭 或异常拉动抽屉时,自关碰件从自关盒的卡位脱离,在弹簧的作用下加速回位撞击自关盒, 导致自关碰件或自关盒损坏,使自关组件失去自关功能,另外,现有自关盒内的导向槽较 低,且无限位作用,安装或使用出现偏差时,自关碰件及转轴件经常会脱出自关盒外,导致 自关组件失去应有功能;还有目前市面上用于抽屉导轨的自关缓冲组件还普遍存在着拉开 抽屉时的拉力比较大,且自关缓冲组件的受力作用点不均勻等缺点,从而导致该自关缓冲 组件的使用寿命短。
技术实现思路
本技术的目的在于克服现有技术的不足,提供了结构更合理、操作比较轻松 ...
