[0024] See also Figure 1-5 The utility model provides a folding headphone stand, which is characterized in that it includes two groups of bases 1, a folding groove 11 is opened on one side of the top of the base 1, and a pulley groove 12 is opened on the side, a scissors frame 2 is slidably connected in the pulley groove 12 between the two groups of bases 1, a rotating shaft seat 3 is rotatably connected at the central intersection of the scissors frame 2, lower arm rods 4 are rotatably connected on both sides of the top of the rotating shaft seat 3, an avoidance groove 13 is opened at the bottom of the folding groove 11, and the avoidance groove 13 runs through the pulley groove 12, the top of the rotating shaft seat 3 is higher than the bottom surface of the folding groove 11 and the raised part is the same thickness as the lower arm rod 4, an upper arm rod 5 is rotatably connected to the top of the lower arm rod 4, a groove matching the lower arm rod 4 is opened on the inner side of the upper arm rod 5, and a support plate 6 is rotatably connected to the top of the upper arm rod 5.

[0025] Furthermore, pulleys 21 are provided at the top of the four corners of the scissors frame 2, the pulley groove 12 is a trapezoidal cavity with an opening at the wider end, the height of the pulley groove 12 is not less than the thickness of the scissors frame 2, and a side cover plate 14 is fixedly installed at one end of the base 1, and the pulley 21 is rollingly connected to the side of the side cover plate 14. When folded, the scissors frame 12 can be completely stored in the pulley groove 12.

[0026] Furthermore, a base frame 31 is provided at the bottom of the rotating shaft seat 3, and a threaded shaft is provided at the top of the base frame 31. The threaded shaft is inserted at the center intersection of the scissors frame 2 and is threadedly connected to the bottom of the rotating shaft seat 3. Limiting grooves 32 are provided on opposite sides of the top of the rotating shaft seat 3. A damping shaft a33 is provided in the limiting groove 32. The outer side of the damping shaft a33 is rotatably connected to the lower arm rod 4. The limiting groove 32 satisfies the vertical 90° rotation limit of the lower arm rod 4.

[0027] Specifically, the rotating shaft seat 3 is rotatably connected to the scissor frame 2, so the rotating shaft seat 3 can be rotated 360 degrees horizontally to adjust the direction.

[0028] Furthermore, shaft holes 41 are provided at both ends of the lower arm 4, and damping shafts b51 are provided at both ends of the upper arm 5. The shaft hole 41 at one end is sleeved on the outside of the damping shaft a33, and the shaft hole 41 at the other end is sleeved on the outside of the damping shaft b51 at one end. The damping shaft b51 at the other end is rotatably connected to a support plate 6. The depth and length of the groove opened on one side of the upper arm 5 are not less than the thickness and length of the lower arm 4. The groove opened on the side of the upper arm 5 can completely fit the lower arm 4 and store it when folded.

[0029] Furthermore, the outer wall of the rotational connection between the upper arm 5 and the lower arm 4 is flush with the end, and the lower arm 4 can be vertically rotated 180° inwardly with the connection with the upper arm 5 as the center and fit into the groove on the inner side of the upper arm 5.

[0030] It is worth mentioning that the outer wall of the rotating connection between the upper arm 5 and the lower arm 4 is flush with the end. Therefore, when the upper arm and the lower arm are rotated to the same vertical line, the outer wall of the upper arm 5 presses against the side of the lower arm to prevent it from continuing to rotate. At this time, the support plate 6 reaches the highest height and will not tip over due to gravity.

[0031] Furthermore, connecting seats are provided at both ends of the bottom of the support plate 6, and mounting holes are opened in the connecting seats. A damping shaft b51 is inserted into the mounting holes. The two ends of the support plate 6 are arc-shaped structures. The arc design at both ends of the support plate 6 is to prevent the earphones from slipping when hanging.

[0032] Furthermore, the inner wall of the rotation connection between the upper arm 5 and the support plate 6 is flush with the end, and the upper arm 5 can be vertically rotated 90° outward with the connection with the support plate 6 as the center.

[0033] It is worth mentioning that the inner wall of the rotating connection between the upper arm rod 5 and the support plate 6 is flush with the end. In the folded state, the upper arm rod 5 is parallel to the bottom of the support plate 6. When opened, the inner wall of the upper arm rod 5 is supported by the side wall of the support plate 6 mounting seat, so that its maximum angle is limited when it is perpendicular to the bottom of the support plate 6. At this time, the support plate 6 is positioned by the upper arm rods 5 at both ends of the bottom to avoid tilting due to uneven gravity at both ends when hanging headphones.

[0034] The working principle of a foldable headphone stand based on a specific embodiment is as follows: a scissor frame 2 is arranged between two groups of bases 1, and the scissor frame 2 slides in the base pulley groove 12 through the pulley 21 to achieve a horizontal folding effect between the bases, and the intersection point of the scissor frame 2 is positioned by a rotating shaft seat 3, and the top of the rotating shaft seat 3 is connected to the lower arm rod 4 and the upper arm rod 5, and a support plate 6 is installed on the top of the upper arm rod 5. The outer side wall of the rotation connection between the upper arm rod 5 and the lower arm rod 4 is flush with the end, so when the upper arm rod and the lower arm rod rotate to the same vertical line, the outer side wall of the upper arm rod 5 presses against the side of the lower arm rod to prevent it from continuing to rotate. At this time, the support plate 6 reaches the highest height and will not Because of the action of gravity, it tilts over. At the same time, the inner wall of the rotating connection between the upper arm rod 5 and the support plate 6 is flush with the end. In the folded state, the upper arm rod 5 is parallel to the bottom of the support plate 6. When opened, the inner wall of the upper arm rod 5 is supported by the side wall of the support plate 6 mounting seat, so that its maximum angle is limited when it is perpendicular to the bottom of the support plate 6. At this time, the support plate 6 is positioned by the upper arm rods 5 at both ends of the bottom to avoid tilting due to uneven gravity at both ends when hanging headphones. The inner side of the upper arm rod 5 has a groove that fits with the lower arm rod 4, and the top of the base 1 has a folding groove 11 and an avoidance groove 13 for accommodating the folded arm rod and the support plate 6, which saves space and makes the overall appearance more beautiful.
