Description

Technical Field

[0001] This utility model belongs to the field of computer processing technology, and in particular relates to a computer keyboard key mounting device. Background Technology

[0002] Computers are one of the most common electronic devices in modern society, and keyboards are one of the most important input devices for computers. They are mainly used to input English letters, Chinese characters, numbers, punctuation marks, etc. into the computer, so as to issue commands to the computer and input data. Among them, the character keys are one of the important structures of the computer keyboard. The character keys mainly include two types: letter keys and number keys, which are used to input English letters and numbers respectively.

[0003] The keys are typically installed on the keyboard using a snap-fit ​​method, and the installation of the keys is usually done manually. Workers snap each key into its designated position on the keyboard. Manual installation is not only time-consuming and labor-intensive, but it is also difficult to control the pressure applied to the keys. This can result in the keys not being installed securely due to insufficient pressure, or the keys or the key mounting structure on the keyboard being damaged due to excessive pressure. The yield rate is low. Furthermore, it is inconvenient to clean the keyboard during manual installation, so dust and other impurities on the keyboard can affect the installation of the keys.

[0004] To address this issue, we provide a computer keyboard key mounting device to solve the problems mentioned above. Utility Model Content
