DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 The weight-adjustable keyboard shown in the figure comprises a keyboard body 1 with a placement opening 2 and a through hole 11 therein. In order to increase the friction between the keyboard body 1 and the workbench, thereby making the keyboard body 1 more stably placed on the workbench, two anti-slip pads 9 are fixedly installed at the bottom of the keyboard body 1, and the through hole 11 is located above the placement opening 2. Two extrusion plates 4 are arranged in the placement opening 2, and a compression spring 5 is fixedly installed on the outer wall of the two extrusion plates 4 on one side close to each other. Moving rods 7 are fixedly installed at the bottom of the two extrusion plates 4, respectively, and the bottom ends of the two moving rods 7 extend to the outside of the keyboard body 1, and the two moving rods 7 are slidably connected to the keyboard body 1. A long strip opening 17 is provided at the bottom of the placement opening 2, and the two moving rods 7 penetrate the long strip opening 17 and are slidably connected to the inner wall of the long strip opening 17. A plurality of counterweight blocks 8 are arranged in the placement opening 2, and other counterweight blocks 8 from the outside are placed in the placement opening 2, thereby increasing the weight of the keyboard body 1. The weight of the keyboard body 1 makes people more stable when typing and improves the typing speed. Two limit plates 13 are slidably installed in the through hole 11. In order to limit the limit plate 13 and thus drive the torsion spring 15 to rotate when the rotating rod 14 rotates, four limit grooves 16 are opened on the inner wall of the through hole 11. The two sides of the two limit plates 13 extend into the four limit grooves 16 respectively and are slidably connected with the inner walls of the corresponding limit grooves 16 respectively. An elastic pull rope 12 is fixedly installed on the outer wall of the side where the two limit plates 13 are close to each other, and a rotating rod 14 is rotatably installed on the outer wall of the side where the two limit plates 13 are away from each other, and a rotating baffle 10 is fixed on the ends of the two rotating rods 14 away from each other. The compression spring 5 will push the two extrusion plates 4 away from each other and contact the counterweight block 8, and then the counterweight block 8 is stably squeezed between the rotating baffle 10 and the extrusion plate 4 to prevent the counterweight block 8 from shaking randomly in the keyboard body 1 and causing inconvenience to people.

[0022] In order to ensure that the rotating baffle 10 can automatically rotate upward to open the placement opening 2 when it is not in contact with the keyboard body 1, and stably maintain the current position, so that people can place the counterweight block 8 into the placement opening 2, the two rotating rods 14 are respectively movably sleeved with torsion springs 15. In order to increase the service life of the torsion spring 15 and the compression spring 5, the surfaces of the torsion spring 15 and the compression spring 5 are tin-plated, and the ends of the two torsion springs 15 that are close to each other are fixedly connected to the corresponding limit plates 13, and the ends of the two torsion springs 15 that are away from each other are fixedly connected to the corresponding rotating baffles 10.

[0023] In order to ensure that the two extrusion plates 4 can remain stably in the current position when people add the counterweight block 8 into the placement opening 2 without affecting people's work, a fixed magnet 3 is fixedly installed in the placement opening 2, and a movable magnet 6 is fixedly installed on the outer wall of the two extrusion plates 4 on the side close to each other. The fixed magnet plate 3 and the movable magnet plate 6 maintain a safe distance from the electronic parts in the keyboard body 1 and will not affect the keyboard body 1.

[0024] The working principle of the weight-adjustable keyboard provided by the utility model is as follows: in the initial state, the compression spring 5 is in a compressed state, the elastic pull rope 12 is in a stretched state, the torsion spring 15 is in a stressed state, and the pulling force of the elastic pull rope 12 on the limit plate 13 is always greater than the compression spring 5 and greater than the extrusion force of the extrusion plate 4. When people need to adjust the weight of the keyboard body 1 itself, they first move the two moving rods 7 closer to each other, and the two moving rods 7 approach each other to drive the two moving magnets 6 closer to each other, so that the two moving magnets 6 are in contact with the fixed magnet 3. At this moment, the magnetic force between the moving magnet 6 and the fixed magnet 3 is greater than the compression elastic force of the compression spring 5, and the two moving magnets 6 are firmly adsorbed on the fixed magnet 3, thereby making the two extrusion plates 4 also stably maintain the current position, and then move the two rotating baffles 10 away from each other and separate from the keyboard body 1, and then rotate the two rotating baffles 10 180° to make the two rotating baffles The plate 10 rotates from a vertical downward state to a vertical upward state to fully reveal the placement opening 2, and the staff can put other external counterweight blocks 8 into the placement opening 2, thereby increasing the weight of the keyboard body 1, making people more stable when typing and improving typing speed. When the external counterweight blocks 8 all enter the placement opening 2, the rotating baffle 10 is rotated 180° to rotate the rotating baffle 10 to its original state to block the placement opening 2 again, and then the two moving rods 7 are moved away from each other to separate the moving magnet 6 from the fixed magnet 3. At this moment, there is no contact between the moving magnet 6 and the fixed magnet 3, resulting in the magnetic force being less than the compression force of the compression spring 5. The compression spring 5 will push the two extrusion plates 4 away from each other and contact with the counterweight block 8, thereby stably squeezing the counterweight block 8 between the rotating baffle 10 and the extrusion plate 4 to prevent the counterweight block 8 from shaking randomly in the keyboard body 1 and causing inconvenience to people.

[0025] Compared with the related art, the weight-adjustable keyboard provided by the utility model has the following beneficial effects:

[0026] The utility model provides a keyboard with adjustable weight. First, two moving rods 7 are moved to drive two moving magnets 6 to contact with fixed magnets 3. At this moment, the magnetic force between the moving magnets 6 and the fixed magnets 3 is greater than the compression elastic force of the compression spring 5. The two moving magnets 6 are firmly adsorbed on the fixed magnets 3, so that the two extrusion plates 4 are stably maintained at the current position. Then, the two rotating baffles 10 are moved away from each other and separated from the keyboard body 1. Then, the two rotating baffles 10 are rotated 180 degrees to reveal the placement opening 2. The staff can place other counterweights outside. 8 is placed into the placement opening 2, thereby increasing the weight of the keyboard body 1, making people more stable when typing and improving typing speed. When the external counterweight blocks 8 enter the placement opening 2, the rotating baffle 10 is rotated 180° to block the placement opening 2, and then the two moving rods 7 are moved away from each other to separate the moving magnet 6 from the fixed magnet 3. The compression spring 5 will push the two extrusion plates 4 to stably squeeze the counterweight block 8 between the rotating baffle 10 and the extrusion plate 4 to prevent the counterweight block 8 from shaking randomly in the keyboard body 1 and causing inconvenience to people.
