Claims

1. A pull cord switch containment device, comprising: include: frame; A pull cord switch includes a body, a rocker arm, and a pull cord. The fixed end of the rocker arm is rotatably connected to the body, and the free end is connected to two pull cords. The two pull cords extend in opposite directions and are perpendicular to the rocker arm. A limiting frame is provided with a limiting groove. The limiting frame is detachably connected to the frame by a threaded fastener extending perpendicular to the axis of the rocker arm, so that the limiting frame can switch between a first position and a second position. When the limiting frame is in the first position, the pull cord switch is arranged at an interval from the limiting member; when the limiting frame is in the second position, the rocker arm is located in the limiting groove, and the free end extends out of the limiting groove.

2. The pull cord switch containment device of claim 1, wherein, The rocker arm is rotatably connected to the body via a pivot, the axial direction of the threaded fastener is parallel to the pivot, and the height of the threaded fastener is lower than the pivot.

3. The pull cord switch containment device of claim 2, wherein, The threaded fasteners are provided in two sets, and the two sets of threaded fasteners are symmetrically arranged with the extension line of the rocker arm as the axis of symmetry.

4. The pull cord switch containment device of claim 3, wherein, The threaded fastener is provided in two parts, and the two threaded fasteners are of the same height.

5. The pull cord switch containment device of any one of claims 1-4, wherein, The threaded fastener includes a screw and a nut connected to the screw.

6. The pull cord switch containment device of any one of claims 1-4, wherein, The frame includes a support plate, a mounting plate, and a reinforcing plate. The mounting plate is connected to the support plate, and the reinforcing plate is connected to both the support plate and the mounting plate. The pull cord switch is mounted on the mounting plate. The threaded fastener is connected to the support plate.

7. The pull cord switch containment device of any one of claims 1-4, wherein, The limiting frame includes connecting arms and connecting rods. There are two connecting arms, which are connected by the connecting rod. The connecting rod and the two connecting arms together form the limiting groove. The threaded fastener is connected to the connecting rod or the connecting arm.

8. The pull cord switch containment device of claim 7, wherein, Both ends of the connecting arm extend out of the connecting rod, and the threaded fastener is connected to the connecting arm.

9. The pull-cord switch sealing device according to claim 7, characterized in that, The connecting arm includes a first arm segment, a second arm segment, and a third arm segment arranged sequentially. The second arm segment is angled to both the first arm segment and the third arm segment. The connecting rod is connected to the junction of the first arm segment and the second arm segment.

10. The pull cord switch containment device of claim 9, wherein, The first arm segment and the second arm segment are perpendicular to each other, and the second arm segment is perpendicular to the third arm segment.
