AI Technical Summary
Existing massage chair backrests have difficulty automatically releasing when they catch small animals or children, and there is interference between the pulling and releasing process of the locking posts.
It adopts a dynamic and static jaw engagement structure. The dynamic jaw engagement is maintained by an elastic adjustment structure to ensure that the pull of the locking pin is not affected. When the force reaches the threshold, it automatically disengages. The flipping frame is driven by torsion springs and compression springs to achieve disengagement.
The massage chair backrest frame automatically releases itself when it gets caught on a foreign object, without affecting the normal pulling of the locking post, while ensuring the simplicity and stability of the structure.

[0013] The specific embodiments of the utility model will be described in detail below in combination with the drawings:
[0014] In the description of the utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0015] The utility model discloses a pin shaft tripping movable and fixed jaw clamping structure applied to a massage chair, including the connecting seat 1, the utility model embodiment case, be provided with static jaw 2 and turnover frame 3 on the connecting seat 1, turnover frame 3 can rotate relative to connecting seat 1, and the movable jaw 4 extending to the position of static jaw 2 is equipped on turnover frame 3, still be equipped with the elastic adjusting structure 6 of driving movable jaw 4 and turning over to form the clamping groove 5 of static jaw 2 on the connecting seat 1.
[0016] Adopting the above scheme: when in use, the product is assembled to the massage chair, at this time, the connecting seat 1 can be assembled to the backrest frame, and the connecting seat 1 is driven to slide relative to the pull rod by the electric push rod, and the clamping column is arranged on the pull rod, at this time, the movable jaw 4 is rotated relative to the fixed jaw 2 to form a clamping tendency, and the movable jaw 4 is kept clamped by the elastic adjusting structure 6, so as not to affect the clamping column to pull the connecting seat 1, and when the backrest frame clamps the foreign matter, the clamping column will be stressed, and when the force reaches a threshold value, the movable jaw 4 can be squeezed to make the turnover frame 3 overturn, so that the clamping column can be separated from the clamping groove 5, adopting the structure can not only pull the clamping column, but also not affect the normal tripping of the clamping column, and the structure is simple and has good stability
