[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 One embodiment of this utility model is a keyboard with a dustproof keyboard cover, including a keyboard body 1, a metal cover 2 hinged to the top of the keyboard body 1, a magnet 3 for attracting the metal cover 2 fixedly installed on the side wall of the keyboard body 1, a support mechanism 4 provided inside the metal cover 2, and an adjustment mechanism 5 provided on the left side of the metal cover 2.

[0035] Reference Figure 2 and Figure 4The support mechanism 4 includes a rotating rod 41. One end of the rotating rod 41 is rotatably connected to the inside of the metal cover 2, and the other end of the rotating rod 41 passes through the metal cover 2 and is fixedly installed with a protrusion 44. The rotating rod 41 is rotatably connected to the metal cover 2 through the protrusion 44, which allows the rotating rod 41 to be rotated easily. A support plate 42 is fixedly installed on the outer wall of the rotating rod 41. The support angle of the support plate 42 can be adjusted by rotating the rotating rod 41. An airbag 43 is fixedly installed on the outer wall of the support plate 42, which can support the user's wrist.

[0036] Reference Figure 5 An L-rod 45 is slidably connected through the inner wall of the protrusion 44. An arc-shaped plate 46 is fixedly installed on the right side of the metal cover 2. The arc-shaped plate 46 and the rotating rod 41 are concentric. A limiting hole 47 is opened on the arc-shaped plate 46. The protrusion 44 can be limited by the limiting hole 47 and the L-rod 45. The outer wall of the L-rod 45 is attached to the inner wall of the limiting hole 47. A limiting spring 48 is sleeved on the outer wall of the L-rod 45. The L-rod 45 is elastically connected to the protrusion 44 through the limiting spring 48. The elasticity of the limiting spring 48 can make the L-rod 45 stably inserted into the limiting hole 47.

[0037] Reference Figure 2 - Figure 3 The adjusting mechanism 5 includes a vacuum box 51, which is fixedly installed on the left outer wall of the metal cover 2. A piston plate 52 is slidably connected to the inner wall of the vacuum box 51. The air inside the vacuum box 51 can be compressed by the sliding of the piston plate 52. A push rod 54 is fixedly installed on the side wall of the piston plate 52. The end of the push rod 54 away from the piston plate 52 passes through the vacuum box 51 and extends to the outside of the vacuum box 51. The push rod 54 is slidably connected to the through point of the vacuum box 51. The piston plate 52 can be pushed by the push rod 54, so that the piston plate 52 slides on the inner wall of the vacuum box 51.

[0038] Reference Figure 3 and Figure 6 A slide plate 55 is slidably connected to the inner wall of the push rod 54. A locking block 56 is fixedly installed on the upper surface of the slide plate 55. The sliding plate 55 drives the locking block 56 to move upward, so that the locking block 56 can fit against the surface of the vacuum box 51. The locking block 56 and the slide plate 55 can limit the push rod 54. A return spring 57 is fixedly installed at the bottom of the slide plate 55. The end of the return spring 57 away from the slide plate 55 is fixedly installed on the inner wall of the push rod 54. When the slide plate 55 is released, the return spring 57 will push the slide plate 55 upward, so that the slide plate 55 drives the locking block 56 to move upward.

[0039] Reference Figure 3A flexible hose 53 is fixedly installed on the inner wall of the vacuum box 51. The end of the flexible hose 53 away from the vacuum box 51 passes through the metal cover 2 and is fixedly installed on the inner wall of the airbag 43. By sliding the piston plate 52 in conjunction with the flexible hose 53, air inside the vacuum box 51 can be injected into the airbag 43 or air inside the airbag 43 can be drawn into the vacuum box 51. The flexible hose 53 is fixedly connected to the metal cover 2 at the point of penetration. The inside of the airbag 43 is connected to the inside of the vacuum box 51 through the flexible hose 53, and the air inside the airbag 43 and the vacuum box 51 can be exchanged through the flexible hose 53.

[0040] Working principle: When in use, rotate the metal cover 2 to disengage it from the magnet 3, and then rotate the metal cover 2 to a horizontal position. At this time, the airbag 43 on the top of the support plate 42 can support the user's wrist, making the user more comfortable to use. When the keyboard body 1 is not in use, rotate the metal cover 2 to cover the top of the keyboard body 1 and make the metal cover 2 adhere to the magnet 3. The magnetic attraction of the magnet 3 can limit the position of the metal cover 2. At the same time, the metal cover 2 can prevent dust from falling into the gaps of the keyboard body 1.

[0041] When the user is using the keyboard body 1, push the L-bar 45 to slide it on the inner wall of the protrusion 44 and stretch the limiting spring 48 until the L-bar 45 moves out of the limiting hole 47. At this time, the rotating rod 41 can be rotated through the protrusion 44, causing the rotating rod 41 to drive the support plate 42 to rotate. The support angle can be adjusted by rotating the support plate 42 so that the airbag 43 can better fit the user's wrist. It can also be freely adjusted according to different users' usage habits. After the adjustment is completed, insert the L-bar 45 into the inside of the limiting hole 47. The limiting hole 47 and the L-bar 45 can limit the protrusion 44, thereby limiting the rotating rod 41, so that the support plate 42 on the outer wall of the rotating rod 41 can maintain a stable support angle.

[0042] When the user is using the keyboard body 1, press down on the slide plate 55 to make it slide on the inner wall of the push rod 54 and compress the return spring 57 until the locking block 56 at the top of the slide plate 55 separates from the surface of the vacuum box 51. Then push the push rod 54 to make the push rod 54 drive the piston plate 52 to slide on the inner wall of the vacuum box 51. Then release the slide plate 55 to make the return spring 57 push the slide plate 55 upward, so that the slide plate 55 drives the locking block 56 to move upward. When the locking block 56 moves upward and fits against the surface of the vacuum box 51, the locking block 56 and the slide plate 55 can limit the push rod 54, so that the piston plate 52 cannot slide on the inner wall of the vacuum box 51.

[0043] As the piston plate 52 slides along the inner wall of the vacuum chamber 51 and gradually moves away from the hose 53, it draws air from inside the airbag 43 into the vacuum chamber 51 through the hose 53, causing the airbag 43 to gradually deflate. At this point, the airbag 43 becomes softer than before. As the piston plate 52 slides along the inner wall of the vacuum chamber 51 and gradually moves closer to the hose 53, it compresses the air inside the vacuum chamber 51, allowing the air inside the vacuum chamber 51 to be injected into the airbag 43 through the hose 53. This causes the airbag 43 to gradually inflate, becoming harder than before. This allows users to freely adjust the firmness of the airbag 43 to their most comfortable state, further improving user comfort.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
