Power-assisted mechanism and ground well cover assembly
The invention provides a power-assisted mechanism and a ground well lid assembly. The power assisting mechanism comprises a torsional spring assembly, a fixing assembly and an adjusting assembly. The torsion spring assembly comprises a torsion spring body, a first adjusting end and a second adjusting end, the fixing assembly comprises a fixing frame, a fixing main shaft and a rotating shaft, the fixing main shaft and the rotating shaft are detachably assembled on the fixing frame, the torsional spring body is detachably arranged on the fixing main shaft in a sleeving mode, and the first adjusting end extends downwards and abuts against the rotating shaft. The adjusting assembly is assembled at the bottom of the fixing frame and comprises a limiting piece and an adjusting piece connected with the limiting piece, the second adjusting end extends downwards and is in limiting fit with the limiting piece, and the adjusting piece drives the limiting piece to enable the limiting piece to move and drives the second adjusting end to rotate around the fixing main shaft in the direction close to the torsion spring body. And the pre-tightening force of the torsional spring assembly is tightened. The pre-tightening force of the torsional spring assembly is adjusted through the adjusting assembly, and the service life of the torsional spring assembly can be prolonged.
本申请提供一种助力机构及地井盖组件。助力机构包括扭簧组件、固定组件及调节组件。扭簧组件包括扭簧主体和连接于扭簧主体两端的第一调节端和第二调节端。固定组件包括固定框架和可拆卸地组装于固定框架的固定主轴和旋转轴，扭簧主体可拆卸地套设于固定主轴，第一调节端朝下延伸且与旋转轴相抵接。调节组件组装于固定框架的底部，且包括限位件和与限位件连接的调节件，第二调节端朝下延伸且与限位件限位配合，调节件驱动限位件，使限位件移动，带动第二调节端绕固定主轴、且朝向靠近扭簧主体的方向旋转，以收紧扭簧组件的预紧力。本申请通过调节组件调节扭簧组件的预紧力，可延长扭簧组件的使用寿命。
