Disclosed in the present invention is a roller height adjusting mechanism, comprising a roller assembly, an adjusting component and a sliding adjusting member, wherein the sliding adjusting member is located on one side of the roller assembly, and comprises a first adjusting portion and a second adjusting portion, which are slidably arranged facing or facing away from each other. The first adjusting portion and the second adjusting portion are both hinged to one end of the adjusting component, the other end of the adjusting component is hinged to the roller assembly, and the first adjusting portion and/or the second adjusting portion is/are slid to open or close the adjusting component, so as to adjust the distance between the roller assembly and the sliding adjusting member, such that a traditional manner of always using bolts to carry out lifting adjustment is changed, thereby improving lifting adjustment convenience. In addition, stress in a lifting adjustment process is alleviated, and doors and windows are more attractive after assembling.
