The invention relates to the technical field of chain falling prevention. The invention discloses a bicycle chain anti-falling device. The bicycle chain anti-falling device comprises a front hub gear,the surface of the front hub gear is rotatably connected with a chain in a meshing manner, one side of the chain is rotatably connected with a rear hub gear in a meshing manner, the surface of the rear hub gear is rotationally connected with an anti-falling device, the anti-falling device comprises a mounting plate fixedly connected with the rear hub gear, one side of the mounting plate is fixedly connected with a supporting rod through a bolt, one side of the supporting rod is fixedly connected with a hanging column, one side of the hanging column is elastically connected with a telescopic spring, and one side of the supporting rod is fixedly connected with a fixing base. According to the bicycle chain anti-falling device, through the use of the anti-falling device, when a bicycle is used, the guide frame faces upwards, the lower fixed wheel extrudes the chain to tighten the chain, so that the phenomena that the edge is loosened and the chain is lengthened are avoided, the chain is prevented from falling off in the riding process, and a rider is protected.
本发明涉及链条防脱落技术领域,且公开了一种自行车链条防脱落装置,包括前轮毂齿轮,所述前轮毂齿轮的表面相啮合转动连接有链条,所述链条的一侧相啮合转动连接有后轮毂齿轮,所述后轮毂齿轮的表面转动连接有防脱落装置,所述防脱落装置包括与后轮毂齿轮固定连接的安装板,所述安装板的一侧通过螺栓固定连接支撑杆,所述支撑杆的一侧固定连接有挂柱,所述挂柱的一侧弹性连接有伸缩弹簧,所述支撑杆的一侧固定连接有固定座。该自行车链条防脱落装置,通过防脱落的装置的使用,在自行车使用时,导型框向上,使下定轮挤压链条,使链条绷紧,从而达到了不会出现松边,链条被拉长,从而阻止了在骑行过程中出现链条脱落的现象,保护了骑行者。
