Description

Technical Field

[0001] The utility model relates to the field of keyboards, in particular to a lifting keyboard. Background Art

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a group of function keys (such as a typewriter or computer keyboard) that are arranged by the system to operate a machine or device. The keyboard is also a part of a keyboard instrument. It can also refer to a musical instrument that uses a keyboard, such as a piano, digital piano or electronic organ. The keyboard helps to practice typing. The keyboard is the most commonly used and most important input device. English letters, Chinese characters, numbers, punctuation marks, etc. can be entered into the computer through the keyboard, thereby issuing commands to the computer, entering data, etc. There are also some keyboards with various shortcut keys. As time goes by, independent products with various shortcut functions are gradually available on the market and sold separately, and come with special drivers and setting software, which can also realize personalized operations on compatible machines. A Chinese patent discloses a liftable keyboard (authorization announcement number CN 208861250 U). The patented technology has a collection groove at each of the four corners of the lower surface of the keyboard body, two of which are parallel to the keyboard body, and the other two are parallel to the short sides of the keyboard body. The two collection grooves with similar short sides are perpendicular to each other. In the four collection grooves, the parts close to the four corners of the keyboard body are rotatably connected to a support leg, and the support leg is vertically rotatably connected to the collection groove through a rotating shaft. When the height of the keyboard body needs to be changed, the support legs in the storage slot are rotated out to make the support legs and the lower surface of the keyboard body perpendicular to each other, so that the support legs can support the keyboard body and increase the height of the keyboard body. When the support legs support the keyboard on the table, the height of the keyboard can be changed by adjusting the support legs, making it more comfortable for people to use the keyboard. However, the support legs of this design can only be raised to a single height and cannot be adjusted, and the lifting mechanism is single. Therefore, those skilled in the art provide a lifting keyboard to solve the problems raised in the above background technology. Utility Model Content
