The roller structure comprises guide rails and cylindrical rollers, wherein the guide rails are arranged at the left end and the right end of a massage chair back frame and the rollers slide on the guide rails and are arranged at the two ends of a walking shaft of the machine core. A cylindrical surface of each of the rollers is provided with an annular groove which is parallel to the two end surfaces of each of the rollers, each annular groove is connected with an O-shaped ring in a fastening manner, the external surface of each O-shaped ring is protruded out of the cylindrical surface of each roller, each protruded O-shaped ring is tightly close to the inner side surface of each of the guide rails, the outer edge of each of the guide rail is fixedly provided with a rack, the inner side of each roller is fixedly provided with a transmission gear, and each transmission gear is meshed with each rack. According to the roller structure of the chair back machine core of the massage chair, disclosed by the utility model, the rollers do not generate offset when sliding on the guide rails, the two end rollers move consistently, the regular operation of the machine core is ensured, the machine blockage is prevented and the service life is prolonged.
Description
Technical field
This utility model relates to a kind of massage chair, relates in particular to a kind of back of massage chair movement roller structure.
Background technology
Existing back of massage chair movement roller structure, because adopting drive motors driving screw mandrel to drive movement slides up and down at guide rail, this structure is comprised of roller and the guide rail at walking axle two ends, roller and guide rail are joined to be incorporated on the guide rail and are rotated, but owing to having the gap between the guide rail at the roller at two ends and two ends, easily cause the two ends roller asynchronous during the roller rolling, rolling wheel wear is serious, even cause the two ends idler wheel dislocation, and cause movement to move up and down stuck, massage armchair can't be turned round.
The utility model content
The purpose of this utility model is to provide a kind of back of massage chair movement roller structure, solved between the guide rail at the roller at existing back of massage chair movement roller structure two ends and two ends and had the gap, roller easily causes the two ends roller asynchronous when rolling, rolling wheel wear is serious, even cause the two ends idler wheel dislocation, cause movement to move up and down stuck, make the massage armchair problem that can't turn round.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of back of massage chair movement roller structure, comprise the guide rail at two ends, the back of massage chair skeleton left and right sides and the columned roller that is positioned at movement walking axle two ends that slides at guide rail, be provided with the annular groove parallel with the roller both ends of the surface on the cylinder of described roller, annular groove is fastenedly connected O type circle, the outer surface of O type circle protrudes the cylinder of roller, the O type circle that protrudes is close to the medial surface of guide rail, be fixedly installed tooth bar on the described guide rail outer edge, the roller inboard is fixedly installed travelling gear, the engagement of driving cog wheel and rack.This back of massage chair movement roller structure is provided with the O type circle of the projection parallel with the roller both ends of the surface at the cylinder of roller, the O type circle of projection just is stuck on the medial surface of guide rail, the engagement of driving cog wheel and rack, roller is slided at guide rail can not deflect, two ends roller motion is consistent, guarantee the normal operation of movement, prevent card machine, increase the service life.
As preferably, be provided with roller housing on the internal ring of described roller, roller is fixedly connected with the walking axle by roller housing.Be convenient to the installation of roller and fastening by this structure.
As preferably, the outer face of described travelling gear is fixedly connected with back-up ring.Prevent that by this structure travelling gear deflection from dropping out tooth bar, causes card machine.
As preferably, be provided with geared sleeve on the described travelling gear internal ring, be provided with bolt hole on the geared sleeve, fastening bolt is set in the bolt hole, travelling gear is fixedly connected with the walking axle by geared sleeve.Be convenient to the installation of travelling gear and fastening by this structure.
As preferably, described roller inside is provided with wheel hub, hollow between wheel hub.Can save the use of material by this structure, save cost.
The beneficial effects of the utility model are: this back of massage chair movement roller structure makes roller slide at guide rail and can not deflect, and roller motion in two ends is consistent, guarantees the normal operation of movement, prevents card machine, increases the service life.
