Unit door easy-to-push overspeed prevention system
The invention discloses a unit door easy-to-push overspeed prevention system. The unit door easy-to-push overspeed prevention system comprises a door body, a rotating shaft is rotatably connected to the door body and an external fixing frame, a rotating cylinder is connected to the side, close to the rotating shaft, of the door body, the rotating shaft is inserted into the rotating cylinder, a sleeve is fixedly connected in the rotating cylinder, the sleeve is located in the rotating cylinder in a one-way communication mode, the inner wall of the sleeve is in sealed sliding connection with a piston, the top of the piston is fixedly connected with a screen, the top of the screen is fixedly connected with a sealing block, the rotating cylinder is filled with buffer liquid, the rotating shaft is fixedly connected with a half-tooth gear, and the half-tooth gear is meshed with a full-tooth gear. The system has the advantages that damping is reduced, pushing force for pushing a door is reduced during normal door pushing, use is convenient, the rotating speed is reduced during accelerated door pushing, and therefore the problem that people are hurt due to the fact that the weight of the unit door is large during quick door opening and closing is solved.
本发明公开了一种单元门易推防过速系统，包括门体，所述门体与外界固定架转动连接有转轴，所述门体靠近转轴的一侧连接有转筒，所述转轴插设至转筒的内部并且在转筒内固定连接套筒，所述套筒单向导通位于转筒中并且套筒的内壁密封滑动连接有活塞，所述活塞的顶部固定连接有网板，所述网板的顶部固定连接有密封块，所述转筒中装满缓冲液体，所述转轴固定连接有半齿轮，所述半齿轮啮合有全齿轮。优点在于：在正常推门时，降低阻尼，减少推门的推力，方便使用，在加速推门时降低转速，从而避免在快速开关门时，由于单元门质量较大，造成伤人的问题。
