Keyboard keycap anti-shedding structure

The present invention provides a keycap anti-drop structure of a keyboard, especially an anti-drop structure for the keycap to be separated from the interlocking structure when pressed, and is provided with a barb body on the bottom surface of the keycap and assembled at the bottom of the keycap. The interlocking structure is provided with a buckled portion for the hook-and-loop body to be snap-fitted, so as to prevent the keycap from falling off and separating when the interlocking structure is assembled on the base for pressing.

Generally, the keyboard for computer application is provided with a linkage structure (such as a scissor foot bracket or a V-shaped bracket) at the bottom of the plurality of key caps constituting the keyboard, so that the key caps can be automatically reset after pressing, and pass through the bottom of each keycap. The circuit system transmits the commands, signals, and the like pressed by the key caps to the host computer, and then displays related information input by the keyboard on the screen, and the plurality of key caps of the keyboard are assembled and interlocked in the docking and fastening manners ( Such as the scissor foot bracket or V-shaped bracket, etc.), but does not form a stable clamping and positioning function, the keyboard is affected by the external force cocking, flipping, etc., so that the pivotal position of each keycap and the interlocking structure Loose or broken, or after the key caps are pressed for a long time, the pivotal positions of the key caps and the interlocking structures are loosened or dropped, and the key caps are easily detached from the top of the interlocking structure. As a result, the key cap is detached from the keyboard, so that the plurality of keycaps of the keyboard still have many defects and problems in practical application.

Therefore, how to solve the assembly of the complex keycap and interlocking structure of the keyboard is not shaped The problem of stability and fixed position, and the lack of looseness and shedding of the multiple keycaps after a period of use is the direction for the relevant manufacturers in this industry to research and improve.

Therefore, the creators have collected relevant information in view of the above problems and shortcomings. Through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, this design can be used to stabilize the keycap assembly on the interlocking structure, and it is not easy to fall off and separate by the external force.
