The invention discloses a door speed limiter. The door speed limiter comprises a base, a roller and a centrifugal rolling rod, the base body is of a frame structure, the frame structure is composed ofthree rectangular plates, a fluctuation plate is arranged on the inner side of one of the rectangular plates on the two sides, the fluctuation plate is an arc plate with the central axis of a rollerrotating hole as the central axis, and protruding blocks are evenly distributed on the lower surface of the arc plate. a roller body is a circular ring shell with a shaft in the center and an openingin one side, the shaft in the center of the roller is matched with the roller rotating hole in the base, and a centrifugal rolling rod sliding groove is formed in the shaft on the opening side of thecircular ring shell and used for being matched with a centrifugal rolling rod outer shell; and the centrifugal rolling rod body is a rectangular block, and a rotating wheel is arranged at one end of the rectangular block and can rotate around a rotating wheel restraining hole in the rectangular block. The problem that an existing door body fixator cannot restrain the speed of the whole movement process of a door body is solved.
本发明公开了一种门限速器，包括基座、滚轮和离心滚动杆；基座主体为框架结构，框架结构由三块矩形板组成，两侧矩形板的其中一个矩形板内侧设有波动板，波动板是以滚轮旋转孔的中心轴线为中心轴线的圆弧板，圆弧板的下表面均布凸起块；滚轮主体为中心有轴的一侧开口圆环壳体，滚轮中心的轴与基座上的滚轮旋转孔相配合，圆环壳体开口侧的轴上设有离心滚动杆滑动槽，用于与离心滚动杆外壳体相配合；离心滚动杆主体为矩形块，矩形块一端设置有旋转轮，旋转轮可绕矩形块上的旋转轮约束孔旋转；解决了现有门体固定器不能实现对门体运动全过程的速度约束问题。
