[0016] The specific implementation of the utility model is described in detail below in combination with the drawings:

[0017] In the description of the utility model, it is understood that the orientation or position relation indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right" and the like is the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it can not be understood as the limitation of the utility model.

[0018] The utility model discloses a kind of warning devices applied to massage chair safety pin, including connecting seat 1 and turnover frame 2, connecting seat 1 is provided with static jaw 3, turnover frame 2 is provided with dynamic jaw 4 at corresponding static jaw 3, dynamic jaw 4 and static jaw 3 cooperate to form occlusion slot 5, in the utility model embodiment, the turnover frame 2 includes pressing end 21 and take-off end 22, and turnover frame 2 is rotatably connected on connecting seat 1 to form warped plate structure, and trigger piece 23 is further provided on turnover frame 2, connecting seat 1 is provided with proximity switch 6 (proximity switch 6 can be sensor or microswitch, can be normally closed switch also can be normally open switch, of course, it can also be the combination of two) at corresponding trigger piece 23 position, further including the limiting structure 7 that limits the automatic turnover of turnover frame 2.

[0019] Using the above scheme, when using, connecting seat 1 is assembled to the backrest frame of massage chair, at this time, the pull rod on the massage chair can act on the occlusion slot 5, when the backrest frame lies down and touches foreign matter, the pull rod is stressed at the cooperation place of occlusion slot 5, at this time, in order to trip, the pull rod will extrude dynamic jaw 4, so that turnover frame 2 is turned over, further, proximity switch 6 is triggered by trigger piece 23, so as to issue an alarm while tripping automatically, the alarm can be an indicator light, a buzzer, of course, proximity switch 6 can also control electric push rod reverse operation through circuit board, further improve safety, and through limiting structure 7, turnover frame 2 can be prevented from rotating automatically, so that it is more stable when using.

[0020] The trigger piece 23 is a spring that can be relatively elastically deformed, and a limiting rod 8 is provided on the outer side of the trigger piece 23 on the connecting seat 1, which can prevent the spring from turning over too much and thus protect the proximity switch 6.

[0021] The limiting structure 7 includes a torsion spring 71 that drives the clockwise rotation of the turnover frame 2 and a compression spring 72 that drives the counterclockwise rotation of the turnover frame 2 (of course, the limiting structure 7 can also use only a torsion spring to maintain the state, which cannot adjust the threshold value but can maintain the state of the turnover frame), the torsion spring 71 is arranged on the connecting seat 1, one end of the torsion spring 71 abuts against the connecting seat 1, and the other end abuts against the turnover frame 2, the dynamic jaw 4 is arranged on the take-off end 22, the compression spring 72 acts on the pressing end 21, and the connecting seat 1 is further provided with an adjusting screw 9 for adjusting the compression amount of the compression spring 72, the adjusting screw 9 is threadedly connected with the connecting seat 1, the turnover frame 2 can be driven to rotate to one side by the torsion spring 71, further, the pressing end 21 is pressed by the compression spring 72, which can overcome part of the torsion of the torsion spring 71, adjust the reverse rotation of the turnover frame 2, and thus adjust the rotation angle of the turnover frame 2, so that the turnover frame 2 maintains the current state and prevents the turnover frame 2 from rotating automatically.

[0022] The adjusting bolt 9 is further provided with a limiting surface 91 for limiting the rotation of the adjusting bolt 9, and the pressing end 21 is provided with a clamp seat 10 corresponding to the position of the limiting surface 91, and the clamp seat 10 is detachably connected with a clamp 101 for limiting the rotation of the adjusting bolt 9 by cooperating with the limiting surface 91. Since the adjusting bolt 9 is matched by threads, the adjusting bolt 9 is easy to rotate by itself, thereby affecting the stability. By abutting the clamp 101 with the limiting surface 91, the self-rotation of the adjusting bolt 9 is prevented, and the clamp 101 is detachably connected with the clamp seat 10, which is convenient for assembly and does not affect the normal adjustment of the adjusting bolt 9.
