Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning structures, in particular to a massager movement gear shaft press-in positioning structure. Background Art
[0002] The principle of the massage chair is to use mechanical rolling force and mechanical force extrusion to perform massage. The massage chair is driven by gears. At the neck position of the massage chair, the movement gear shaft is assembled with the movement gear by interference fit.
[0003] The existing massager movement gear shaft press-in positioning structure (publication number: CN220427437U) has at least the following disadvantages:
[0004] When the above patent is in use, the gear is first placed in the gear positioning groove, and then the first base is moved to the bottom of the guide assembly. After that, the gear shaft is passed through the first through hole on the guide plate and plugged into the floating block for positioning. Then the hydraulic cylinder drives the pressure block downward, and the pressure block presses the guide plate and the gear shaft downward together. The guide plate forms a positioning for the gear shaft when it is pressed downward, effectively ensuring the assembly effect of the gear shaft. After the movement gear shaft is pressed into the movement gear, the user needs to manually remove the assembled assembly from the inside of the gear positioning groove. The gap between the gear positioning groove and the driving pressure block is small, and the user is likely to touch the pressure head when manually taking it, causing hand injuries.

[0024] The slide plate 11 is moved upward by the action force of the first spring 9, and the slide plate 11 drives the bevel 19 of the L-shaped bracket 18 to leave the chamfer. At this time, the V-shaped clamp 17 clamps the movement gear shaft 13 again, and the movement gear 12 and the movement gear shaft 13 are brought out of the interior of the positioning circular groove 5 through the slide plate 11. After the movement gear shaft 13 is pressed, the movement gear 12 and the movement gear shaft 13 can be brought out of the interior of the positioning circular groove 5 by this device, avoiding hand injuries caused by the operator manually taking the assembly, thereby ensuring the safety of the operator.
[0025] In this embodiment, a through hole is penetrated through the upper surface of the slide plate 11, and the through hole is arranged between the two T-shaped slide grooves 14. The inner wall of the through hole is slidably inserted with a movement gear shaft 13, and the two V-shaped clamps 17 are against the outer surface of the movement gear shaft 13. The two T-shaped slide grooves 14 are each provided with a second spring 16. The two ends of the second spring 16 are respectively fixedly installed on the outer surface of the T-shaped slider 15 and the inner wall of the T-shaped slide groove 14. The second spring 16 is arranged between the inner walls of the T-shaped slide groove 14 close to the side of the limiting slide column 7.
[0026] Through the action force of the second spring 16, the T-shaped slider 15 slides close to each other along the T-shaped slide groove 14, and the T-shaped slider 15 drives the V-shaped clamping plate 17 to fix the position of the movement gear shaft 13 to prevent it from sliding out of the inside of the through hole; the telescopic rod 2 drives the pressure head 3 to move downward through the mounting plate, so that the pressure head 3 drives the movement gear shaft 13 to move downward, and the movement gear shaft 13 slides along the through hole and the V-shaped opening.
