Description

Technical Field

[0001] This utility model relates to the field of keyboard armrest technology, specifically an independently adjustable keyboard armrest. Background Technology

[0002] A keyboard armrest is an ergonomic aid designed to enhance keyboard comfort. Its design conforms to the natural shape of the wrist, providing soft support for the wrist while typing, helping to maintain a neutral and relaxed wrist posture. This effectively reduces fatigue and pressure from prolonged keyboard use. It also features flexible adjustability to adapt to different users' desktop environments, keyboard types, and usage habits, ensuring the wrist receives just the right amount of support during typing, thus reducing the risk of wrist strain and enhancing a lasting comfortable experience during work or leisure.

[0003] Most keyboard armrest designs on the market today focus on a single wrist support function. Fixed structures or designs that only support limited height and angle adjustments make it difficult for users to flexibly adjust the distance between their wrists and the keyboard according to different desktop depths, keyboard sizes, or personal sitting habits. Furthermore, they lack a protection mechanism for the keyboard itself. When frequently disassembling or adjusting the position of the keyboard armrest, the edge of the armrest is prone to friction and bumps against the keyboard surface. Long-term use may cause scratches on the keyboard shell or even damage to the keys. Auxiliary functions such as dustproof and splashproof are also rarely involved, making it difficult to meet users' needs for long-term clean and safe use of the keyboard.

[0004] Therefore, we propose an independently adjustable keyboard armrest. Utility Model Content

[0005] The purpose of this invention is to provide an independently adjustable keyboard armrest to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an independently adjustable keyboard armrest, comprising: A keyboard, with an armrest installed below it; An adjustment mechanism is provided on both sides of the armrest. The adjustment mechanism includes suction cups. Suction cups are installed on both sides of the keyboard. A fixing rod is installed on the top of the suction cup. A connecting block is rotatably installed on the outside of the fixing rod. A first connecting rod is fixedly connected to the front end of the connecting block. A second connecting rod is rotatably installed on the outside of the armrest. The protective mechanism includes a movable groove. Movable grooves are provided on both sides of the handrail. Movable rods are slidably installed inside the movable grooves. A cover plate is fixedly connected between the two movable rods. Toothed grooves are provided on the top of both sides of the cover plate.

[0007] Preferably, anti-slip pads are installed at equal intervals on the bottom of the handrail.

[0008] Preferably, the adjustment mechanism further includes locking holes. Locking holes are sequentially and equidistantly arranged inside the first connecting rod, and a locking rod is slidably installed inside the second connecting rod. The suction cup is connected to both sides of the keyboard. Then, the connecting block is operated to move the first and second connecting rods towards each other. Since the first and second connecting rods are slidably connected, the distance the first and second connecting rods move towards each other can be adjusted according to usage requirements. Once a suitable position is reached, the locking rod slidably installed inside the second connecting rod is operated to connect the locking rod to the locking hole inside the first connecting rod, thereby ensuring positional stability.

[0009] Preferably, the protective mechanism further includes a drive gear. Drive gears are rotatably mounted on both sides of the inner wall of the armrest. The outer side of the drive gear is meshed with the cover plate via a toothed groove. Driven gears are rotatably mounted on both sides of the armrest, and the driven gears are fixedly connected to the drive gears internally. Operating the movable lever and pulling it downwards along the movable groove causes the cover plate to move downwards as well. The downward movement and unfolding of the cover plate covers the lower half of the keyboard, achieving overall protection and dust prevention for the keyboard.

[0010] Preferably, the front end of the handrail is symmetrically fixedly connected to fixed plates. A rotating gear is rotatably mounted on the outer side of each fixed plate, and the outer side of the rotating gear meshes with a driven gear. A rotating rod is rotatably mounted between the two fixed plates, and both ends of the rotating rod pass through the interior of the fixed plates and are fixedly connected to the driven gear. Brushes are sequentially and equidistantly mounted on the outer side of the rotating rod. When the cover plate returns to its original position, the engagement of the toothed grooves drives the driving gear to rotate. The rotation of the driving gear drives the driven gear to rotate, which in turn drives the rotating gear meshing with it on the outer side to rotate. The rotation of the rotating gear drives the rotating rod to rotate, which in turn drives the brushes mounted on the outer side to rotate. During the rotation of the brushes, the dust accumulated on the surface of the cover plate is swept away, preventing dust from entering the interior of the handrail.

[0011] Preferably, the top of the handrail has a sliding groove, and a sliding block is slidably installed inside the sliding groove. A brush plate is fixedly connected to the front end of the sliding block. By moving the sliding block within the sliding groove, the movement of the sliding block drives the brush plate to move, which in turn sweeps away the dust accumulated on the surface of the handrail, thus achieving the dust cleaning function.

[0012] Preferably, ventilation openings are symmetrically provided on both sides of the handrail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the adjustment mechanism allows users to freely adjust the distance between the armrest and the keyboard according to their own sitting posture, desktop layout and keyboard size, ensuring that the wrist is always in a natural and relaxed neutral posture, avoiding arm compression due to being too close or shoulder and neck suspension due to being too far away, thereby effectively dispersing typing pressure and reducing muscle fatigue; the protection mechanism enables the armrest to protect the keyboard, the armrest can resist liquid spills and dust intrusion, extend the life of the internal components of the keyboard, reduce cleaning and maintenance costs, and keep the keyboard looking new and performing stably during long-term use.
