Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-4, the utility model discloses a key support connection structure, including installing in upper cover 1, center 2 and the inside support 4 of lower cover 3, support 4 includes two stands 5, both ends are connected with the screw thread section of thick bamboo 6 with upper cover 1 and 3 threaded connection of lower cover about two stands 5, two stands 5 are equipped with draw-in groove 7 with relative direction, the PCB board 8 has been placed in the draw-in groove 7, the button 9 is installed to PCB board 8, be connected with crossbeam 10 between two stands 5, the slidable mounting has button post 11 about

crossbeam

10, 11 one end of button post and button 9 overlap joint, the button overlap joint on the button 11 other end and the installation on upper cover 1 is pressed to the button.

In this embodiment, when using a key-holder connection structure, install PCB board 8 through draw-in groove 7, the setting of draw-in groove 7, prevented PCB board 8 front and back displacement, with button post 11 slidable mounting on crossbeam 10, then put into center 2 with support 4, furthermore, can cooperate lower cover 3 to carry out the position reinforcement to PCB board 8, install upper cover 1 and lower cover 3 in the upper and lower both sides of center 2 through a screw section of thick bamboo 6, at this moment, press the button on the upper cover 1 and just can drive button post 11 and move down, thereby conflict button 9, realize the signal transmission to PCB board 8.
