[0002] The utility model relates to an armrest, in particular to a rotating and lifting armrest, belonging to the technical field of e-sports chair armrests. Background Art

[0003] An e-sports chair is a special chair designed for e-sports competitions. Its design conforms to ergonomics, can provide a comfortable sitting posture and support, and helps players stay comfortable and focused during long gaming sessions. E-sports chairs usually have adjustable seat height, tilt angle, backrest angle, etc., and can be customized according to the needs of players.

[0004] E-sports chair armrests are usually installed on both sides of an e-sports chair, which can provide support for players' hands. During the use of existing e-sports chair armrests, since most armrests adopt an integrated design and cannot be flexibly adjusted according to the needs of users, the user experience is poor, affecting the overall comfort of the e-sports chair. Therefore, a rotating and lifting armrest is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a rotating and lifting armrest to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of the embodiment of the utility model is realized as follows:

[0007] A rotating and lifting armrest includes a fixed component. One side of the fixed component is fixedly connected with a connecting component, and a supporting component is installed on the top of the connecting component. It is characterized in that the supporting component includes a connecting block, a second connecting plate, a supporting plate, and a cushion plate. The second connecting plate is installed on the top of the supporting plate, the supporting plate is connected to the cushion plate at the top, the connecting block is fixedly connected with a support and a connecting shaft at the top. A ball groove is opened on the upper surface of the support, and balls are installed inside the ball groove. The second connecting plate is rotatably connected to the outer side wall of the connecting shaft.

[0008] Preferably, the supporting component further includes a second limiting block, a third connecting plate, and a limiting groove. The second limiting block is fixedly connected to the top of the second connecting plate, the third connecting plate is slidably connected to the inner side wall of the supporting plate, a limiting groove is opened on the upper surface of the third connecting plate, and the second limiting block is rotatably connected to the inside of the limiting groove.

[0009] Preferably, the support assembly further includes a pre-tightening spring, a top block, and a slot. Two pre-tightening springs are symmetrically and fixedly connected to the inner side wall of the third connecting plate. One end of each pre-tightening spring is fixedly connected to a top block. Slots are evenly arranged on the inner side wall of the support plate, and the top blocks are inserted into the slots.

[0010] Preferably, the connecting assembly includes a sleeve, a support rod, a first limiting block, a limiting hole, a sliding rod, and a clamping slot. The sleeve is fixedly connected to the outer side wall of the support rod. A first limiting block is fixedly connected to the top of the support rod. A limiting hole is formed in the lower surface of the first limiting block. A sliding rod is arranged on the inner side wall of the support rod. A clamping slot is formed in the outer side wall of the sliding rod. A fixed shaft and a rotating shaft are fixedly connected to the top of the sliding rod. A button is installed outside the fixed shaft and the rotating shaft. A spring slot is formed in the upper surface of the button. A reset spring is fixedly connected inside the spring slot. When the button is not subject to external force, it is pushed out of the sleeve under the action of the reset spring. At this time, the clamping slot cooperates with the first limiting block to prevent the sliding rod from moving up and down. When the button is pushed inward, the button drives the rotating shaft to move, while the fixed shaft remains stationary all the time. Therefore, the sliding rod is driven to rotate and aligns with the limiting hole. At this time, the user can pull the sliding rod to move. After adjustment in place, the button is released, and the button pops up under the action of the reset spring and drives the sliding rod to rotate, and the clamping slot is engaged with the first limiting block again.

[0011] Preferably, the fixing assembly includes a fixing plate, a fixing bolt, a first connecting plate, a sliding groove, a connecting bolt, a nut, and a locking handle. The fixing bolt is installed on the inner side wall of the fixing plate. The first connecting plate is slidably connected to the inner side wall of the fixing plate. A sliding groove is formed in the upper surface of the first connecting plate. A nut is arranged on the inner side wall of the fixing plate. The connecting bolt is threadedly connected to the nut. One end of the connecting bolt penetrates through the sliding groove. A locking handle is installed on the outer side wall of the connecting bolt. The sliding groove cooperates with the connecting bolt to limit the sliding distance of the first connecting plate. The locking handle is used to press or loosen the first connecting plate.

[0012] Since the embodiment of the present invention adopts the above technical solutions, it has the following advantages:

[0013] The utility model fixes the first connecting plate through a locking handle. By rotating the locking handle, the first connecting plate can be loosened so that it can slide along the bottom of the fixing plate to adjust the distance between the two armrests. The first limiting block plays a limiting role on the sliding rod. The sliding rod can be rotated by pushing the button to align it with the limiting hole, thus facilitating the user to pull the armrest up and down to change the supporting height of the armrest. Through the cooperation of the second limiting block and the limiting groove, the user can adjust the angle of the armrest within a certain range. By using the pre-tightening spring to press against the top block and the cooperation of the top block and the slot, it is convenient for the user to adjust the extending length of the armrest. By setting a connecting shaft, the second connecting plate and the armrest can rotate freely horizontally by 360°. By setting a ball on the top of the support base, the rotation resistance of the second connecting plate can be reduced, thereby improving the adjustment freedom of the armrest of the gaming chair, enabling the armrest to slide horizontally back and forth and left and right and rotate without limit by 360°, improving the user experience and enhancing the overall comfort of the gaming chair.

Detailed implementation mode

[0024] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0026] As Figures 1-6 shown, an embodiment of the present invention provides a rotary lifting armrest, which includes a fixing component 10. The fixing component 10 includes a fixing plate 11, a fixing bolt 12, a first connecting plate 13, a sliding groove 14, a connecting bolt 15, a nut 16 and a locking handle 17;

[0027] The inner side wall of the fixing plate 11 is evenly provided with fixing bolts 12. The inner side wall of the fixing plate 11 is slidably connected with a first connecting plate 13. The upper surface of the first connecting plate 13 is provided with a sliding groove 14. The inner side wall of the fixing plate 11 is provided with a nut 16. The inside of the nut 16 is threadedly connected with a connecting bolt 15. One end of the connecting bolt 15 penetrates through the sliding groove 14. A locking handle 17 is installed on the outer side wall of the connecting bolt 15. The fixing plate 11 is fixed to the gaming chair through the fixing bolts 12, 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 randomly by pressing. When it is necessary to move the first connecting plate 13, rotating the locking handle 17 can loosen the first connecting plate 13 and reduce the friction between the first connecting plate 13 and the fixing plate 11;

[0028] One side of the fixing component 10 is fixedly connected with a connecting component 20, and the top of the connecting component 20 is provided with a support component 30.

[0029] In this embodiment, specifically, the connecting component 20 includes a sleeve 21, a support rod 22, a first limiting block 23, a limiting hole 24, a sliding rod 25, a clamping groove 26, a fixed shaft 27, a rotating shaft 28, a button 29, and a spring groove 210;

[0030] One side of the first connecting plate 13 is fixedly connected to a support rod 22, and the outer wall of the support rod 22 is fixedly connected to a sleeve 21. The sleeve 21 and the support rod 22 play a role in connection and support.

[0031] In this embodiment, specifically, the top of the support rod 22 is fixedly connected to a first limiting block 23, and a limiting hole 24 is formed on the lower surface of the first limiting block 23. The shape of the limiting hole 24 is the same as that of the sliding rod 25.

[0032] In this embodiment, specifically, a sliding rod 25 is arranged on the inner side wall of the support rod 22. Clamping grooves 26 are evenly formed on the outer wall of the sliding rod 25. A fixed shaft 27 and a rotating shaft 28 are fixedly connected to the top of the sliding rod 25. A button 29 is installed outside the fixed shaft 27 and the rotating shaft 28. A spring groove 210 is formed on the upper surface of the button 29, and a reset spring is fixedly connected inside the spring groove 210. Through the above settings, under the action of the reset spring, the button 29 is ejected from the sleeve 21 when not affected by an external force. At this time, the clamping groove 26 on the outer wall of the sliding rod 25 cooperates with the first limiting block 23 to prevent the sliding rod 25 from moving up and down. When the height of the armrest needs to be adjusted, the button 29 is pushed inward. The button 29 can drive the rotating shaft 28 to move, while the fixed shaft 27 remains stationary all the time. Therefore, the sliding rod 25 is driven to rotate and align with the limiting hole 24. At this time, the user can pull the sliding rod 25 to move. After adjustment in place, the button 29 is released, and the button 29 bounces under the action of the reset spring and drives the sliding rod 25 to rotate, and the clamping groove 26 is engaged with the first limiting block 23 again.

[0033] In this embodiment, specifically, the support component 30 includes a connecting block 31, a second connecting plate 32, a support plate 33, a cushion plate 34, a second limiting block 35, a third connecting plate 36, a limiting groove 37, a pre-tightening spring 38, a top block 39, a slot 310, a support 311, a ball groove 312, and a connecting shaft 313;

[0034] The inner side wall of the sleeve 21 is fixedly connected to a connecting block 31. A support 311 and a connecting shaft 313 are fixedly connected to the top of the connecting block 31. Ball grooves 312 are evenly formed on the upper surface of the support 311, 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 horizontally freely.

[0035] In this embodiment, specifically: a second limiting block 35 is fixedly connected to the top of the second connecting plate 32, a support plate 33 is installed on the top of the second connecting plate 32, a cushion plate 34 is fixedly connected to the top of the support plate 33, the inner side wall of the support plate 33 is slidably connected to a third connecting plate 36, a limiting groove 37 is formed on the upper surface of the third connecting plate 36, and the second limiting block 35 is rotatably connected to the inside of the limiting groove 37. The cushion plate 34 is made of an elastic material, which can improve the user's comfort during the support process.

[0036] In this embodiment, specifically: two pre-tightening springs 38 are symmetrically and fixedly connected to the inner side wall of the third connecting plate 36, and one end of each pre-tightening spring 38 is fixedly connected to a top block 39.

[0037] In this embodiment, specifically: slot holes 310 are evenly arranged on the inner side wall of the support plate 33. With the above settings, both ends of the second limiting block 35 are made of plastic material. Since there are hollow structures at both ends, when the second limiting block 35 rotates relative to the limiting groove 37, the second limiting block 35 undergoes elastic deformation under force and returns to its original shape after entering a new slot position. Therefore, the frictional resistance continuously changes during the rotation process, ensuring that the user cannot rotate the armrest randomly. Similarly, the top block 39 is subjected to the pre-tightening pressure of the pre-tightening spring 38 and requires an appropriate external force to slide along the slot holes 310 to realize the forward and backward movement of the armrest.

[0038] When the present utility model works: 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 plays a role in limiting the sliding rod 25. The sliding rod 25 can be rotated by pushing the button 29 to align it with the limiting hole 24, so as to facilitate the user to pull the armrest up and down to change the support height of the armrest. Through the cooperation of the second limiting block 35 and the limiting groove 37, the user can adjust the angle of the armrest within a certain range. By the pre-tightening spring 38 pressing against the top block 39 and using the cooperation of the top block 39 and the slot holes 310, it is convenient for the user to adjust the extending length of the armrest. By providing the connecting shaft 313, the second connecting plate 32 and the armrest can rotate freely horizontally by 360°. By arranging balls on the top of the support 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, enabling the armrest to slide horizontally forward, backward, left and right and rotate without limit by 360°, improving the user's experience and enhancing the overall comfort of the gaming chair.

[0039] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
