DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] Example: Refer to Figures 1 to 3 A combined multi-angle adjustable mechanical keyboard includes a keyboard body 1. The keyboard body 1 is a prior art known in the art, and its specific structure and working principle will not be elaborated in detail herein.

[0022] It also includes a connecting plate 2 fixedly connected to the lower end of the keyboard body 1, with two sliding grooves 3 symmetrically provided on the connecting plate 2, a slider 4 slidably connected in the sliding groove 3, a return spring 6 fixedly connected between the slider 4 and the sliding groove 3, and two sliders 4 are slidably connected to two blocks 5, and an arc groove is provided on the block 5, and the shape of the arc groove is adapted to the shape of the lifting rod 13 described below.

[0023] Two rotating holes are symmetrically provided at both ends of the connecting plate 2, and two through holes 8 are symmetrically provided on the U-shaped plate 7. The through holes 8 are slidably connected with rotating pins 9 that are plugged into the rotating holes. A limit spring 10 is fixedly connected between the rotating pin 9 and the through holes 8. When the keyboard body 1 is installed in the angle adjustment assembly, the two rotating pins 9 are pulled in opposite directions, and the two limit springs 10 are stretched to increase the distance between the two rotating pins 9. The two rotating holes on the connecting plate 2 on the lower side of the keyboard body 1 are aligned with the two rotating pins 9, and then the two rotating pins 9 are loosened, and the rotating pins 9 are plugged into the rotating holes to complete the rotational connection between the angle adjustment assembly and the keyboard body 1, and the block 5 on the lower side of the connecting plate 2 is placed at the rear end of the lifting rod 13 to make the keyboard body 1 in an inclined state.

[0024] An angle adjustment component is provided on the lower side of the keyboard body 1. Specifically, the angle adjustment component includes a U-shaped plate 7, on which a bidirectional threaded rod 11 is rotatably provided. The left end of the bidirectional threaded rod 11 passes through the U-shaped plate 7 and is coaxially fixedly connected to a handle 15. The handle 15 includes a turntable 151 coaxially fixedly connected to the bidirectional threaded rod 11. A rotating rod 152 is fixedly connected to the eccentric portion of the turntable 151, so that the turntable 151 can be driven to rotate by controlling the rotating rod 152, thereby driving the bidirectional threaded rod 11 to rotate.

[0025] The rod body of the bidirectional threaded rod 11 is reversely threadedly sleeved with two threaded sleeves 12, and the lower ends of the two threaded sleeves 12 are slidably connected to the inner bottom wall of the U-shaped plate 7 to limit the threaded sleeves 12. When the bidirectional threaded rod 11 rotates, it can drive the two threaded sleeves 12 to slide relative to or away from each other on the rod body of the bidirectional threaded rod 11.

[0026] The upper end of the threaded sleeve 12 is rotatably connected to a connecting rod 14, and the upper ends of the two connecting rods 14 are rotatably connected to a lifting rod 13. Two guide grooves are symmetrically fixedly connected to the U-shaped plate 7, and the two guide grooves are slidably connected to the lifting rod 13. The two guide grooves can guide and limit the lifting rod 13 to ensure the sliding stability of the lifting rod 13.

[0027] The specific working principle of the utility model is as follows:

[0028] When adjusting the angle of the keyboard body 1, the rotating rod 152 on the handle 15 is rotated to drive the turntable 151 to rotate, drive the bidirectional threaded rod 11 to rotate, drive the two threaded sleeves 12 to slide relative to each other, reduce the relative distance between the two threaded sleeves 12, drive the lifting rod 13 to rise through the two connecting rods 14, drive the block 5 to slide, and stretch the reset spring 6, so that the angle of the keyboard body 1 becomes larger. Similarly, the rotating rod 152 on the handle 15 is rotated to drive the turntable 151 to rotate in the opposite direction, drive the two threaded sleeves 12 to slide back to each other, and increase the distance between the two threaded sleeves 12. The lifting rod 13 is driven downward through the two connecting rods 14. Under the elastic force of the reset spring 6, the block 5 moves to always abut against the lifting rod 13 to ensure the stability of the keyboard body 1.
