[0042] Please refer to Figure 1-7 , the present utility model provides a spherical support universal adjustable armrest base, which includes:

[0043] Bottom plate 1;

[0044] Ball seat 2, the ball seat 2 is arranged on the bottom plate 1, a spherical rotating shaft 3 is arranged on the ball seat 2, an inclined surface 4 is arranged on the ball seat 2, and the inclined surface 4 is inclined downward from the center of the spherical rotating shaft 3 to the edge of the ball seat 2;

[0045] The rotating shaft assembly 5 is provided with a spherical groove 6, and the rotating shaft assembly 5 is rotatably connected to the spherical rotating shaft 3 through the spherical groove 6.

[0046] The rotating shaft assembly 5 includes a main shaft rod 51, a bushing 52 and an outer sleeve 53. A connecting portion 7 is provided at the bottom of the main shaft rod 51. A first stepped surface 71 is formed between the connecting portion 7 and the main shaft rod 51. A first hemispherical groove 61 is provided on the connecting portion 7. The bushing 52 is detachably connected to the main shaft rod 51. A second hemispherical groove 62 is provided on the bushing 52. The first hemispherical groove 61 and the second hemispherical groove 62 form the spherical groove 6. The outer sleeve 53 is sleeved on the main shaft rod 51, and the bottom of the outer sleeve 53 abuts against the first stepped surface 71. The main shaft rod and the bushing are two independent components. During installation, the bushing is removed, and then the spherical rotating shaft is placed between the first hemispherical groove and the second hemispherical groove, and the bushing is fixed. This can reduce the assembly difficulty of the rotating shaft assembly and the spherical rotating shaft, and is convenient for disassembly, maintenance and replacement. The outer sleeve can hide the connection part of the main shaft rod and the bushing, making the overall appearance more beautiful. At the same time, the first stepped surface can play a role in supporting the outer sleeve to prevent the outer sleeve from contacting the bottom plate and interfering with the rotation of the main shaft rod.

[0047] A first screw hole 8 is provided on the bushing 52, and a bolt 9 is arranged in the first screw hole 8. The bolt 9 passes through the first screw hole 8 and is connected to a second screw hole 10 on the main shaft rod 51. The first screw hole is a countersunk screw hole, which can avoid the bolt protruding from the surface of the bushing. The fixing method using bolts is convenient for installation and disassembly.

[0048] A pressure ring 11 is provided on the main shaft rod 51, and the pressure ring 11 is located at the first stepped surface 71.

[0049] A copper sleeve 12 is arranged between the outer sleeve 53 and the main shaft rod 51. The bottom of the copper sleeve 12 abuts against a second stepped surface 13 on the outer sleeve 53. An annular stop 14 is provided at the top of the copper sleeve 12, and the annular stop 14 is clamped on the inner wall of the outer sleeve 53. The copper sleeve is sleeved on the main shaft rod. The copper sleeve can reduce the friction between the outer sleeve and the main shaft rod. The second stepped surface and the annular stop can prevent the copper sleeve from moving up and down, ensuring the smooth rotation of the outer sleeve.

[0050] An installation seat 15 is provided on the outer sleeve 53, and an auxiliary shaft rod 16 is provided on the installation seat 15. A through hole 17 is provided at one end of the auxiliary shaft rod 16. In this way, the rotation of the outer sleeve can drive the auxiliary shaft rod to rotate, and at the same time, the auxiliary shaft rod can also rotate on the installation seat.

[0051] One end of the auxiliary shaft rod 16 is provided with a baffle 18, the baffle 18 abuts against the end of the mounting seat 15, the other end of the auxiliary shaft rod 16 is provided with a cover plate 19, and the cover plate 19 is sleeved on the auxiliary shaft rod 16.

[0052] On both sides of the mounting seat 15, a first limiting plate 20 and a second limiting plate 21 are respectively arranged, and both the first limiting plate 20 and the second limiting plate 21 are fixedly connected to the bottom plate 1. The rotation distance of the mounting seat can be limited.

[0053] Two waist-shaped holes 22 are arranged on the bottom plate 1. The waist-shaped holes facilitate the connection of the bottom plate with other components.

[0054] Working principle: A ball seat is arranged on the bottom plate, a spherical rotating shaft is arranged on the ball seat, a spherical groove matched with the spherical rotating shaft is arranged at the bottom of the main shaft rod. Through the cooperation of the spherical rotating shaft and the spherical groove, the main shaft rod can rotate around the spherical rotating shaft to achieve the purpose of adjusting the angle. A slope is arranged on the ball seat, and the slope inclines downward from the spherical rotating shaft to the edge of the ball seat. During the up and down movement of the bottom plate, it can rotate by an angle, which is the angle formed by the included angle between the bottom plate and the horizontal plane, and the included angle is 0 - 4°, such as Figure 3 angle C in the figure, to achieve the purpose of adjusting the angle between the bottom plate and the rotating shaft assembly.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
