Abstract

The utility model discloses an anti-derailment joined V-belt transmission structure which comprises a connecting device, and the inner wall of the connecting device is rotationally connected with a transmission device. According to the connecting device and the transmission device, due to the fact that the anti-falling baffles are arranged on the two sides of the first belt wheel and the two sides of the second belt wheel, when the V belt tends to be derailed, the anti-falling baffles can rapidly block the V belt, and the V belt is prevented from falling off. When the V belt needs to be disassembled, the threaded rod is rotated reversely to loosen the tension wheel, the pull ring is pulled to enable the anti-disengaging baffle to slide inwards to relieve limiting, the V belt can be disassembled easily, the position is flexibly adjusted through the rotating button, the threaded rod and the connecting block, and the tension degree of the tension wheel to the V belt is changed. The problems of slipping and derailing caused by insufficient tension force can be avoided, and excessive abrasion of the belt and the belt pulley caused by overlarge tension force can be prevented.
