The invention relates to the field of machinery, in particular to a telescopic conveying roller structure. The telescopic conveying roller structure is implemented by the following technical scheme: the telescopic conveying roller structure comprises an axially telescopic central spindle, two supporting frames, a first roller, a second roller, and two rotating subassemblies, wherein the two supporting frames are respectively and fixedly connected with the two ends of the central spindle; the first roller is fixedly connected with one of the supporting frames in a sleeving manner; the second roller is radially and oppositely fixed, slidably connected with the first roller in a sleeving manner and fixedly connected with the other supporting frame in a sleeving manner; the two rotating subassemblies are respectively fixedly connected with the supporting frames; the rotating subassemblies comprise turntables, first ball bearings, fixed trays, second ball bearings, and first balls; the turntables are fixedly connected with the corresponding supporting frames and rotatably connected with the central spindle in a sleeving manner; the first ball bearings are arranged between the turntables and the central spindle; the fixed trays are connected with the outer part of the central spindle in a sleeving manner; the second ball bearings are arranged between the fixed trays and the central spindle; the first balls are arranged between the turntables and the fixed trays. The telescopic conveying roller structure disclosed by the invention can effectively improve the applicability of the conveying roller.
Description
Technical field [0001] The invention relates to the field of machinery, in particular to a telescopic conveying roller structure. Background technique [0002] The length of the conveying rollers in the prior art is generally a fixed size, which has greater limitations in application. Summary of the invention [0003] The purpose of the present invention is to provide a telescopic transport roller structure, thereby effectively improving the applicability of the transport roller. [0004] The above-mentioned technical purpose of the present invention is achieved by the following technical solutions: a telescopic conveyor roller structure, including an axially telescopic shaft core, two support frames respectively fixedly connected to the two ends of the shaft core, fixed sleeves The first roller body of one of the support frames is relatively fixed and axially sliding sleeved on the first roller body and fixedly sleeved on the second roller body of the other support frame, respecti...
