Overload protection device, transmission device and closestool
The embodiment of the invention provides an overload protection device. The overload protection device comprises a shaft sleeve, a friction shaft and a first elastic hoop. The friction shaft is sleeved in the mounting hole and is provided with a second transmission connecting part; the first elastic hoop comprises a first clamping groove, a first free end and a second free end are bent to define a first annular body capable of elastically expanding or contracting, the sectional area of the first annular body is smaller than the outer diameter of the friction shaft, and the first annular body is arranged on the outer wall of the friction shaft in a sleeving mode. When a torsion which is bear by at least one in a first clamping position and a second clamping position is overload, the cross-sectional area of the first annular body is expanded, so that the first annular body and the friction shaft slip. According to the overload protection device, power can be transmitted, power transmission is cut off through the first annular body and the friction shaft when torsion is overloaded, and loss caused by overload is avoided. The invention further provides a transmission device and a closestool.
本申请实施例提供了一种过载保护装置，过载保护装置包括轴套，摩擦轴以及第一弹性环箍。摩擦轴套设于安装孔内，摩擦轴设置有第二传动连接部；第一弹性环箍包括第一卡槽，第一自由端和第二自由端弯折围成可弹性扩张或收缩的第一环形体，第一环形体的截面积小于摩擦轴的外径，第一环形体套设于摩擦轴的外壁，当第一卡位和第二卡位中的至少一者受到的扭力过载时，第一环形体的截面积扩张，以使第一环形体与摩擦轴打滑。本申请提出的过载保护装置能够传递动力，并在扭力过载时通过第一环形体与摩擦轴使动力的传递断开，避免了过载造成损失。本申请还提供了传动装置和马桶。
