Description

Technical Field

[0001] The utility model relates to the technical field of e-sports chair armrests, and particularly relates to an adjustable e-sports chair armrest. Background Technique

[0002] The armrest design of e-sports chairs has a great impact on comfort and health, especially during long hours of gaming or working. A suitable armrest can reduce the burden on the arms and avoid muscle fatigue or joint discomfort caused by maintaining an improper posture for a long time.

[0003] At present, when the existing e-sports chair armrests on the market are in use, it is usually not convenient to adjust the height individually, but rather the armrest is driven to rise and fall by adjusting the overall height of the seat, which is rather cumbersome during adjustment. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable e-sports chair armrest to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An adjustable e-sports chair armrest, comprising

[0007] An armrest body, a sleeve is provided in the middle of the bottom end of the armrest body, a support rod is movably installed inside the sleeve, and an ejection mechanism is provided between the sleeve and the support rod;

[0008] A side shell is provided below the left side of the armrest body, and an adjustment mechanism is provided between the side shell, the armrest body and the sleeve.

[0009] Preferably, the ejection mechanism includes a second spring, the second spring is provided above the inside of the sleeve, and the other end of the second spring is connected to the upper end of the support rod;

[0010] Preferably, side grooves are opened on both inner walls at the upper end of the sleeve, a friction wheel is movably installed inside the side grooves, and the friction wheel is slidably connected to the outer wall of the support rod;

[0011] Preferably, the adjustment mechanism includes a gear, the gear is movably installed in the middle of the upper end of the side shell, a first rack and a second rack are respectively engaged with the upper and lower ends of the gear, a connecting piece connected to the second rack is vertically provided below the side shell, a positioning rod is provided on the front surface of the bottom end of the connecting piece, and a plurality of positioning grooves matching the positioning rod are opened on the left side of the support rod;

[0012] Preferably, the adjusting mechanism further includes a movable groove. A movable groove is formed at the upper left end of the armrest body. A pressing block is arranged inside the movable groove. A first spring is arranged between the pressing block and the movable groove. The bottom end of the pressing block is fixedly connected to the first rack.

[0013] Preferably, a guiding groove is arranged on one side of the armrest body close to the movable groove. A guiding rod matched with the guiding groove is arranged on the right side of the pressing block.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. For the adjustable armrest of the gaming chair, during adjustment, press the pressing block at the upper end of the armrest body inward. The pressing block drives the first rack to move. The first rack drives the gear to rotate. The gear drives the second rack to move. The second rack pulls out the positioning rod from the positioning groove through the connecting piece. In this way, the sleeve and the support rod are unlocked. After the sleeve and the support rod are unlocked, the armrest body is bounced up by the elastic mechanism until it rises to a suitable height and then the pressing block is released. At this time, the first spring controls the pressing block to reset, and the positioning rod will be inserted into the positioning groove at the current position again to fix, so as to achieve the purpose of facilitating quick adjustment.

[0016] 2. For the adjustable armrest of the gaming chair, when the sleeve and the support rod are unlocked, the sleeve is bounced up by the elastic force of the second spring. During the rising process of the sleeve, the friction wheel inside the side groove will roll along the outer wall of the support rod. Since the friction wheel and the support rod have rolling friction, the rising speed of the sleeve is slow when it rises, so as to avoid hurting the arm due to rapid rising.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-4 shown, a technical solution provided by the present invention is as follows:

[0024] An adjustable e-sports chair armrest includes an armrest body 1. A sleeve 2 is provided in the middle of the bottom end of the armrest body 1. A support rod 3 is movably installed inside the sleeve 2. An ejection mechanism is provided between the sleeve 2 and the support rod 3. The ejection mechanism includes a second spring 5. The second spring 5 is provided above the inside of the sleeve 2. The other end of the second spring 5 is connected to the upper end of the support rod 3. Side grooves 6 are opened on both inner walls at the upper end of the sleeve 2. A friction wheel 7 is movably installed inside the side groove 6. The friction wheel 7 is slidably connected to the outer wall of the support rod 3.

[0025] In this embodiment, when the sleeve 2 and the support rod 3 are unlocked, the sleeve 2 rises under the elastic force of the second spring 5. During the rising process of the sleeve 2, the friction wheel 7 inside the side groove 6 will roll along the outer wall of the support rod 3. Since the friction wheel 7 and the support rod 3 have rolling friction, the rising speed of the sleeve 2 is slow when it rises, so as to avoid injuring the arm due to rapid rising.

[0026] As Figure 2 and Figure 3 shown, a side shell 4 is provided below the left side of the armrest body 1. An adjustment mechanism is provided between the side shell 4, the armrest body 1 and the sleeve 2. The adjustment mechanism includes a gear 8. The gear 8 is movably installed in the middle of the upper end of the side shell 4. A first rack 9 and a second rack 10 are respectively engaged with the upper and lower ends of the gear 8. A connecting member 11 connected to the second rack 10 is vertically provided below the side shell 4. A positioning rod 12 is provided on the front surface of the bottom end of the connecting member 11. A plurality of positioning grooves 13 matching the positioning rod 12 are opened on the left side of the support rod 3. The adjustment mechanism further includes a movable groove 14. The movable groove 14 is opened at the upper left side of the armrest body 1. A pressing block 15 is provided inside the movable groove 14. A first spring 16 is provided between the pressing block 15 and the movable groove 14. The bottom end of the pressing block 15 is fixedly connected to the first rack 9. A guiding groove 17 is provided on one side of the armrest body 1 close to the movable groove 14. A guiding rod 18 matching the guiding groove 17 is provided on the right side of the pressing block 15.

[0027] In this embodiment, during adjustment, the pressing block 15 at the upper end of the armrest body 1 is pressed inward. The pressing block 15 drives the first rack 9 to move. The first rack 9 drives the gear 8 to rotate. The gear 8 drives the second rack 10 to move. The second rack 10 pulls out the positioning rod 12 from the positioning groove 13 through the connecting member 11. In this way, the sleeve 2 and the support rod 3 are unlocked. After the sleeve 2 and the support rod 3 are unlocked, the armrest body 1 is ejected by the ejection mechanism until it rises to an appropriate height and then the pressing block 15 is released. At this time, the first spring 16 controls the reset of the pressing block 15, and the positioning rod 12 will be inserted into the positioning groove 13 at the current position again to be fixed, so as to achieve the purpose of facilitating quick adjustment.
