As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] As shown in Figures 1-6, the embodiment of the present invention provides a rotating lifting armrest, including a fixing assembly 10, the fixing assembly 10 including a fixing plate 11, a fixing bolt 12, a first connecting plate 13, a slide groove 14, a connecting bolt 15, a nut 16 and a locking handle 17;

[0029] The bottom of the fixing plate 11 is formed with two mating grooves 111 opened opposite to each other, and the two sides of the first connecting plate 13 are correspondingly inserted into the two mating grooves 111;

[0030] The inner wall of the fixing plate 11 is evenly provided with fixing bolts 12, and the inner wall of the fixing plate 11 is slidably connected to the first connecting plate 13. The upper surface of the first connecting plate 13 is provided with a sliding groove 14, and the inner wall of the fixing plate 11 is provided with a nut 16. The internal thread of the nut 16 is connected to the connecting bolt 15, and one end of the connecting bolt 15 passes through the sliding groove 14.

The sliding groove 14 cooperates with the connecting bolt 15 to limit the sliding distance of the first connecting plate 13. The locking handle 17 is used to tighten or loosen the first connecting plate 13, that is, the sliding groove 14 on the first connecting plate 13 can cooperate with the connecting bolt 15 to limit the sliding distance of the first connecting plate 13. The locking handle 17 at the bottom prevents the first connecting plate 13 from sliding at will by tightening. When the first connecting plate 13 needs to be moved, the locking handle 17 can be turned to loosen the first connecting plate 13, thereby reducing the friction between the first connecting plate 13 and the fixing plate 11;

[0031] A connecting assembly 20 is fixedly connected to one side of the fixing assembly 10 , and a supporting assembly 30 is installed on the top of the connecting assembly 20 .

[0032] In this embodiment, specifically: the connecting assembly 20 includes a sleeve 21, a support rod 22, a first limiting block 23, a limiting hole 24, a sliding rod 25, a card slot 26, a fixed shaft 27, a rotating shaft 28, a button 29 and a spring slot 210;

The upper surface of the button 29 is provided with a spring groove 210, and the inside of the spring groove 210 is fixedly connected with a reset spring. Through the above arrangement, under the action of the reset spring, the button 29 is ejected from the sleeve 21 without external force. At this time, the slide rod 25 The card slot 26 on the outer wall cooperates with the first limit block 23 to prevent the slide bar 25 from moving up and down. When the armrest height needs to be adjusted, the button 29 is pushed inward. The button 29 can pull the rotating shaft 28 to move, while the fixed shaft 27 always remains stationary, thereby driving the slide bar 25 to rotate and align it with the limit hole 24. At this time, the user can pull the slide bar 25 to move. After adjusting it into place, release the button 29. Under the action of the reset spring, the button 29 pops up and drives the slide bar 25 to rotate, and the card slot 26 is engaged with the first limit block 23 again.

[0036] In this embodiment, specifically: the support assembly 30 includes a connecting block 31, a second connecting plate 32, a supporting plate 33, a pad 34, a second limiting block 35, a third connecting plate 36, a limiting groove 37, a preload spring 38, a top block 39, a slot 310, a bracket 311, a ball groove 312 and a connecting shaft 313;

[0037] The inner wall of the sleeve 21 is fixedly connected to the connecting block 31, the top of the connecting block 31 is fixedly connected to the bracket 311 and the connecting shaft 313, the upper surface of the bracket 311 is evenly provided with ball grooves 312, and balls are installed inside the ball grooves 312. The second connecting plate 32 is rotatably connected to the outer wall of the connecting shaft 313, and the second connecting plate 32 can rotate freely horizontally.

[0038] In this embodiment, specifically: the second limit block 35 has a main body 351 and protrusions 352 located on opposite sides of the main body 351, the edge of the limit groove 37 is provided with two protrusions 371 protruding toward the main body 351, the main body 351 is located between the two protrusions 371, the main body 351 and the two protrusions 371 separate the limit groove 37 into two accommodating grooves 372, the two protrusions 352 are respectively located in the two accommodating grooves 372, and the edges of the two accommodating grooves 372 are provided with multiple slots 373 that cooperate with the protrusions 352.

[0039] In this embodiment, specifically: the top of the second connecting plate 32 is fixedly connected to the second limit block 35, the top of the second connecting plate 32 is installed with a support plate 33, the top of the support plate 33 is fixedly connected to the pad 34, the inner side wall of the support plate 33 is slidably connected to the third connecting plate 36, the upper surface of the third connecting plate 36 is provided with a limit groove 37, the second limit block 35 is rotatably connected to the inside of the limit groove 37, and the pad 34 is made of elastic material, which can improve user comfort during the support process.

[0040] In this embodiment, specifically: two pre-tightening springs 38 are symmetrically fixedly connected to the inner side wall of the third connecting plate 36 , and one end of the pre-tightening spring 38 is fixedly connected to a top block 39 .

[0041] In this embodiment, specifically: the inner side wall of the support plate 33 is evenly provided with slots 310, and the top block 39 is inserted into the slot 310. Through the above setting, both ends of the second limit block 35 are made of plastic material. Since there is a hollow structure at both ends, when the second limit block 35 and the limit slot 37 rotate relative to each other, the second limit block 35 is elastically deformed by force, and restores its original shape after entering the new slot. Therefore, the friction resistance changes continuously during the rotation process, ensuring that the user cannot rotate the armrest at will. Similarly, the top block 39 is subject to the pre-tightening pressure of the pre-tightening spring 38, and appropriate external force is required during the sliding process along the slot 310 to realize the forward and backward movement of the armrest.

[0042] When the utility model is in operation, the first connecting plate 13 is pressed and fixed by the locking handle 17, and the first connecting plate 13 can be loosened by rotating the locking handle 17 so that it can slide along the bottom of the fixing plate 11 to adjust the distance between the two armrests. The first limiting block 23 limits the sliding rod 25, and the sliding rod 25 can be rotated by pushing the button 29 to align it with the limiting hole 24, so that it is convenient for the user to pull the armrest up and down to change the support height of the armrest. The second limiting block 35 cooperates with the limiting groove 37 to allow the user to adjust the support height within a certain range. The angle of the armrest can be adjusted within the range, and the pre-tightened spring 38 is used to tighten the top block 39. The top block 39 cooperates with the slot 310 to facilitate the user to adjust the extended length of the armrest. By setting the connecting shaft 313, the second connecting plate 32 and the armrest can rotate freely 360° horizontally. By setting a ball on the top of the bracket 311, the rotation resistance of the second connecting plate 32 can be reduced, thereby improving the adjustment freedom of the armrest of the gaming chair, allowing the armrest to slide horizontally back and forth, left and right, and rotate 360° without restriction, improving the user experience and enhancing the overall comfort of the gaming chair.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
