The invention discloses chain loosening and tightening equipment for a motorcycle. The equipment comprises a fixing plate, a fixing hole is formed in the center of the upper end of the front wall of the fixing plate, a fixing screw is arranged in the fixing hole, a connecting plate is arranged at the lower end of the front wall of the fixing plate, a cavity is formed in the connecting plate, a first through hole is formed in the center of the top of the cavity, a second through hole is formed in the center of the bottom of the cavity, a moving column is arranged in the cavity, and a threaded rod is in threaded connection with the top end of the moving column. Two chain wheels are arranged, a connecting rod is rotated to make the two chain wheels in contact with a chain and in engaged connection with the chain to change the tightness degree of the chain, when the chain is too long, and a handle is rotated to drive the threaded rod to rotate to make a movable column move up and down, sothe height of the two chain wheels is changed, and the tightness degree of the chain is further controlled. The equipment is easy and convenient to operate, high in practicability and worthy of beingwidely popularized.

    本发明公开了一种摩托车用链条松紧设备,包括固定板,固定板前壁上端的中心处设置有固定孔,固定孔内设置有固定螺丝,固定板前壁的下端设置有连接板,连接板的内部设置有腔室,腔室的顶部的中心处设置有第一贯穿孔,腔室的底部的中心处设置有第二贯穿孔,所述腔室内设置有移动柱,移动柱的顶端螺纹连接有螺纹杆。本发明中通过设置两个链轮,转动连接杆,使得两个链轮与链条接触并与链条啮合连接,从而改变链条的松紧程度,当链条过长时,转动把手带动螺纹杆转动,使得移动柱上下移动,从而改变两个链轮的高度,进一步控制链条的松紧程度,操作简便,实用性较强,值得大力推广。
