The purpose of this utility model is achieved by the following technical solution: a kind of back of electric massage chair is massaged the mechanism that walks up and down, include the backrest general frame, be fixed on the backrest general frame on, the guide pillar fixing head of following both sides, be fixed on, two parallel guide pillars between the following guide pillar fixing head, device has the walking plate of slide block, the walking plate is driven along guide pillar slippage up and down by screw mandrel, it is characterized in that: on the described guide pillar, each coaxial being provided with the end face of guide pillar of following two ends constitutes step-like cylinder boss, the post hole of the diameter of this cylinder boss and guide pillar fixing head is suitable, and cylinder boss penetrates in the post hole of guide pillar fixing head and by nut or screw and guide pillar fixing head secure fit.The step surface that installs and fixes guide pillar in this utility model and be by the guide pillar two ends then is fixed on the guide pillar fixing head by screw or nut as the location, and the step surface at guide pillar two ends can accurately process mechanically, therefore accurate positioning, and connect easy accessibility by screw or nut, thermal deformation situation as the welding manner appearance can not appear, therefore can guarantee the depth of parallelism of two guide pillars, thereby it is light when making the displacement of walking plate, slide block on the walking plate is not easy to wear, has guaranteed that slide block has the life-span.
Guide pillar in this utility model can be set as solid shape, also can be made as hollow form, can reduce cost and be set as hollow form, specifically be set to: described guide pillar is a hollow column jacket, coaxially at the two ends of hollow column jacket be embedded with cylinder with the level, the bigger diameter end of cylinder be inserted in hollow column jacket and bigger diameter end wall and with the hollow pipe post jamb by colding pressing the depression secure fit, the miner diameter end of cylinder constitutes described cylinder boss.
Guide pillar is being set as under the prerequisite of hollow, in order to guarantee that cylinder firmly is fixed in the two ends of hollow column jacket exactly, this utility model also is set to: the inwall at the two ends of described hollow column jacket is evenly distributed in several convex tendons or groove, insert scarf at the convex tendon of the corresponding inwall that is evenly distributed in several grooves or convex tendon and hollow column jacket two ends of the bigger diameter end periphery wall of cylinder or groove and close, the bigger diameter end of cylinder is inserted in behind the hollow column jacket by the wall depression secure fit of colding pressing.
In this utility model, guide pillar is to be provided with like this when being fixed on the guide pillar fixing head by the screw mode: the center of the miner diameter end of described cylinder is provided with screwed hole, and the cylinder miner diameter end is fastenedly connected and is fixed on the guide pillar fixing head with screw after being inserted in the post hole of guide pillar fixing head.
In this utility model, guide pillar can also be fixed on the guide pillar fixing head by the nut mode certainly, concrete scheme is: the coaxial in addition protruding length of the miner diameter end of described cylinder has double-screw bolt, and the miner diameter end of cylinder is inserted in that its double-screw bolt and nut are fastenedly connected and are fixed on the guide pillar fixing head behind the post hole of guide pillar fixing head.
