[0025] Please refer to Figures 1-5 , the utility model provides two technical schemes:

[0026] Embodiment one, a rotatable adjustable seat armrest, comprising:

[0027] Armrest body 1, the surface of armrest body 1 is provided with soft pad, the inside of armrest body 1 is provided with through slot 2, the bottom of the inner wall of through slot 2 is provided with round slot 3, the left side of armrest body 1 is fixedly connected with synchronous block 4;

[0028] Rotating assembly 5, one side of rotating assembly 5 is fixedly connected with one side of synchronous block 4, and rotating assembly 5 is used for freely rotating seat armrest;

[0029] The storage assembly 6 is rotationally connected to the inner wall of the circular groove 3, and is used for temporary and reliable storage of articles. With the arrangement of the rotating assembly 5, the horizontally rotating handrail allows the user to adjust the distance between the handrail and the body, avoiding shoulder compression or suspension discomfort caused by the handrail being too wide or too narrow. The adjustable handrail helps to find the best support position and distribute pressure. The user only needs to press the sliding ring 53 to separate the positioning gear 55 from the toothed ring 58, and then rotate the handrail body 1. After rotating and adjusting to the desired position, release the sliding ring 53, and the spring 52 will automatically rebound and reset the positioning gear 55. The positioning gear 55 and the toothed ring 58 are re-engaged, and the device enters a stable state. The operation is very simple.

The rotating assembly 5 includes a rotating cylinder 51 connected to the synchronous block 4. The bottom of the inner wall of the rotating cylinder 51 is fixedly connected with a spring 52. The spring 52 is used in an environment with stable load, low frequency vibration, small amplitude, and low energy dissipation requirement, so it does not need to be equipped with a damper. The top end of the spring 52 is fixedly connected with a sliding ring 53. The center of the sliding ring 53 is fixedly connected with a synchronous rod 54. The surface of the synchronous rod 54 is fixedly connected with a positioning gear 55. The bottom end of the synchronous rod 54 is fixedly connected with a circular block 56. The surface of the circular block 56 is movably sleeved with a bottom cylinder 57. The surface of the inner wall of the bottom cylinder 57 is fixedly connected with a toothed ring 58. The teeth on the inner surface of the toothed ring 58 and the teeth of the positioning gear 55 are adapted to each other. The surface of the bottom cylinder 57 is fixedly connected with an embedded ring groove 59. The inner wall of the embedded ring groove 59 is movably connected with a ring track plate 510. The surface of the ring track plate 510 is fixedly connected with a support cylinder 511. The top of the support cylinder 511 is fixedly connected with the bottom of the rotating cylinder 51. Before use, the bottom of the bottom cylinder 57 is stably installed in a fixed position. The support cylinder 511 and the ring track plate 510 slide on the surface of the embedded ring groove 59, which can further improve the stability of the handrail body 1 when rotating. The storage assembly 6 includes a rotating shaft 61 rotationally connected to the inner wall of the bottom of the circular groove 3. The rotating shaft 61 is a damping shaft. The top end of the rotating shaft 61 is fixedly connected with a swinging frame 62. The bottom of the inner wall of the swinging frame 62 is fixedly connected with a cup cylinder 63. The inner wall of the cup cylinder 63 is fixedly connected with a non-slip pad 64. The material of the non-slip pad 64 includes but is not limited to silicone. The surface of the swinging frame 62 is fixedly connected with a protective plate 65 through a connecting block. The outer material of the protective plate 65 is a soft and skin-friendly material, including but not limited to pure cotton and cashmere. With the arrangement of the storage assembly 6, various temporary use articles can be placed in the swinging frame 62. After rotating the rotating shaft 61, the swinging frame 62 can be taken out after being turned outwards as a whole. If necessary, a beverage can be placed in the cup cylinder 63, which can be stably clamped by the non-slip pad 64 for convenient use.

[0031] Meanwhile, the contents not described in detail in the specification are all existing technologies known to those skilled in the art.

[0032] In operation, the elbow can be normally placed on the top of the armrest body 1 for use, and in adjustment, the slide ring 53 is pressed down, and the synchronous rod 54 and the positioning gear 55 are moved down at the same time, and the spring 52 is compressed, the positioning gear 55 is separated from the tooth ring 58, the armrest body 1 is rotated, the cylinder 51, the supporting cylinder 511 and the annular track plate 510 are rotated on the surface of the embedded ring groove 59, when the armrest body 1 is rotated to the appropriate angle, the slide ring 53 is released, the spring 52 pushes the slide ring 53 to reset, and the positioning gear 55 is moved up to be re-engaged with the tooth ring 58, the protection plate 65 is pushed, and the swing frame 62 is directly rotated around the rotating shaft 61, when most of the surface of the swing frame 62 is exposed from the armrest body 1, the swing frame 62 can be normally used, the beverage cup can be inserted into the cup cylinder 63, and the anti-skid pad 64 can fully clamp it, and when the device is used, the device is restored.
