The invention, which belongs to the technical field of the electric power-assisted bicycle, discloses a torque sensor for a convenient-to-mount electric power-assisted bicycle, the torque sensor comprises a middle shaft, and one side of the middle shaft is sleeved with an induction sleeve. According to the invention, a mounting pipe sleeve is manually operated to be screwed into a fixed pipe sleeve, so that a second annular cylinder extrudes an air bag, and air in the radial direction of the air bag is compressed to the axial direction of the air bag under the condition that the air in the air bag is not changed, so that the air bag drives an elastic clamping block to seal a cable; according to the utility model, an external water source is prevented from entering the detection circuit from the cable to influence the use performance of the detection circuit, so that the sealing performance of the product in use is ensured, and the sealing performance among the first tooth bowl, the output sleeve and the induction sleeve is ensured through an annular gasket and a second sealing gasket; and external dust and rainwater are prevented from entering the five-way sleeve, a detection circuit in the five-way sleeve is prevented from being rusted for a long time, and the use precision of the detection circuit is further prevented from being influenced.

    本发明公开了一种便装式电动助力自行车用扭矩传感器,属于电动助力自行车技术领域,包括中轴,所述中轴的一侧套设有感应套筒。本发明中,手动操作安装管套使其旋入至固定管套的内部,使第二环形筒对气囊进行挤压,在气囊内部气体不变的情况下,将气囊径向方向的气体压缩至气囊的轴向方向,使其带动弹性夹紧块对线缆处进行密封,防止外部水源从线缆进入到检测电路中,对检测电路的使用性能造成影响,进而保证了产品在使用时的密封性能,通过设置的环形垫片和第二密封垫保证了第一牙碗、输出套筒和感应套筒之间的密封性,防止外部灰尘和雨水进入到五通套管的内部,长时间使五通套管内部的检测电路产生锈蚀,进而对检测电路的使用精度造成影响。
