[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-6 A linear Hall magnetic axis keyboard comprises a keyboard body 1, a cover body 2 is arranged above the keyboard body 1 (the cover body 2 can cover the keyboard body 1, so as to prevent dust from falling on the keyboard when it is not used for a long time), an angle adjustment component is arranged inside the cover body 2 (to adjust the inclination angle of the keyboard, so as to prevent the user from constantly lowering his head to look at the corresponding keys on the keyboard), the angle adjustment component comprises a rotating shaft 9 rotatably connected to the inner wall of the cover body 2, a relatively arranged gear ring 10 is fixedly connected to the surface of the rotating shaft 9, a relatively arranged tooth plate 8 is slidably connected to an inner side surface of the cover body 2, the tooth plate 8 is meshed with the gear ring 10, and a plurality of trapezoidal top blocks 4 are arranged between the two tooth plates 8 (the keyboard body 1 is pushed upward by the trapezoidal top blocks 4, so that the keyboard body 1 is tilted), wherein two trapezoidal top blocks 4 are respectively fixedly connected to the two tooth plates 8, the top ends of the plurality of trapezoidal stoppers are fixedly connected to a connecting plate 5, and a trapezoidal block 3 is fixedly connected to an inner side surface of the cover body 2.

[0024] Furthermore, a through hole is provided at one end of the cover body 2, a connecting shaft 6 fixedly connected to one end of the rotating shaft 9 is arranged in the through hole, a handle 601 is fixedly connected to the surface of the connecting shaft 6, and a rubber sleeve 7 sleeved on the surface of the connecting shaft 6 is arranged in the through hole (the rubber sleeve 7 increases the friction between the connecting shaft 6 and the rubber sleeve 7, thereby preventing the connecting shaft 6 from rotating under non-human influence).

[0025] It should be noted that the keyboard body 1 and the cover body 2 are connected by a rotating connection assembly, which includes a guide rail 101 fixedly connected to both ends of the keyboard body 1, a round tube slidably connected in the guide rail 101, a slide groove is provided at both ends of the cover body 2, a connecting tube is slidably connected in the slide groove, and a connecting rod 201 is rotatably connected between the connecting tube and the round tube.

[0026] It is worth noting that: a plurality of heat dissipation holes are provided at both ends of the cover 2 (the heat dissipation holes can dissipate the temperature of the keyboard body 1, thereby preventing the keyboard body 1 from being overheated and causing the internal permanent magnet to fail), two groups of notches are provided at both ends of the cover 2, and two groups of sliding blocks are slidably connected to the top of the inner part of the cover 2, and one end of the sliding block is fixedly connected to a moving tube 1101 slidably connected to the notch;

[0027] A round rod 1201 is provided in contact with the inner wall of the cover body 2, a push rod 11 is rotatably connected between the movable tube 1101 and the round rod 1201, a U-shaped support plate 12 is fixedly connected to the surface of the round rod 1201 (the push rod 11 and the U-shaped support plate 12 push up the keyboard body 1, so that there is a certain distance between the keyboard body 1 and the heated keyboard pad, thereby preventing the permanent magnet in the keyboard body 1 from failing due to excessive temperature), a slot is provided on the surface of the movable tube 1101, and the slots in each group of movable tubes 1101 are connected by a U-shaped clip 13 (the U-shaped clip 13 fixes the push rod 11, thereby pushing up the keyboard body 1).

[0028] A further advantage of adopting the above method is that the above device dissipates heat for the keyboard body 1, lowers the temperature of the keyboard body 1, thereby preventing the permanent magnet in the keyboard body 1 from failing due to excessive temperature, and at the same time adjusts the inclination angle of the keyboard body 1 according to the state of the user's upper body, eliminating the need for the user to constantly lower his head to look at the corresponding keys on the keyboard body 1, and at the same time covers the keyboard body 1 when not in use, preventing dust from falling on the keyboard body 1 when not in use for a long time.

[0029] When the utility model is in use: when the user needs to use the Hall magnetic axis keyboard, the user rotates the cover body 2 to the bottom of the keyboard body 1, and then the user moves the movable tube 1101 in each slot toward the middle, so that the two push rods 11 rotate and approach each other, and drive the round rod 1201 and the U-shaped support plate 12 to move upward, and push the keyboard body 1 upward, and then the user plugs the U-shaped clip 13 into the movable tube 1101 to fix it, so that the distance between the keyboard body 1 and the cover body 2 is increased, thereby preventing the heated keyboard pad from transferring heat to the keyboard body 1, thereby preventing the permanent magnet in the keyboard body 1 from failing due to heat, and thus preventing the keyboard body 1 from being unusable.

[0030] When the inclination angle of the keyboard body 1 needs to be adjusted, the user holds the handle 601 and rotates it. The rotation of the handle 601 drives the connecting shaft 6 to rotate. The rotation of the connecting shaft 6 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the two gear rings 10 to rotate. The two gear rings 10 rotate to move the two tooth plates 8 and drive the multiple trapezoidal top blocks 4 to move, so that the multiple trapezoidal top blocks 4 move up along the inclined surface of the trapezoidal block 3, and push the keyboard body 1 in the horizontal state upward to make it slowly tilted (when the keyboard body 1 slowly tilts, it will drive the connecting rod 201 and the round tube to move upward). The staff can adjust the inclination angle of the keyboard body 1 to a suitable angle by rotating the handle 601.

[0031] When the keyboard body 1 is not to be used for a long time, the user first adjusts the inclined keyboard body 1 to a horizontal state through the handle 601, then pulls the cover body 2 out from the bottom of the keyboard body 1, rotates the cover body 2, and rotates the cover body 2 to the top of the keyboard body 1 to cover the keyboard body 1. The above device can adjust the inclination angle of the keyboard body 1 according to the state of the user's upper body, without the user having to constantly lower his head to look at the corresponding keys on the keyboard body 1. At the same time, the keyboard body 1 is covered when not in use to prevent dust from falling on the keyboard body 1 when not in use for a long time.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
