Detailed Description

Referring to fig. 1, an easy-to-press key mainly includes a button cover 100, a housing 200, a PCB 400, and a base 600.

Therein, referring to fig. 4, the housing 200 includes a cylindrical barrel wall 210 and a centrally located web 220. The connecting plate 220 has a central hole 230 at the center, and four hook holes 240 spaced near the inner side of the wall. The hooking holes 240 are circumferentially spaced apart by 90 degrees around the center hole 230.

The button cover 100 is also circular, and referring to fig. 2, a pressing column 110 is disposed at the center of the bottom, and four hooks 120 are correspondingly disposed at the bottom near the edge. The pressing post 110 can be inserted into the central hole 230, and the four hooks 120 can be inserted into the four hook holes 240, respectively.

The bottom of the connection board 220 is provided with a PCB board 500, the PCB board 500 is circular, and the center of the upper surface is provided with a switch 410. The PCB board is further provided with three screw holes 420, and three positioning notches 430 are arranged at the edge of the PCB board at intervals. Be equipped with silica gel pad 300 between shell roof 200 bottom and the PCB board 400 top, it can let press and feel more softly, and is difficult for the noise of sending. Referring to fig. 5, a sleeve 310 is disposed in the center of the silicone pad 300, three screw holes 320 are further disposed on the silicone pad 300, and three positioning notches 330 are disposed at the edge at intervals.

The bottom of the housing 200 is provided with a base 600. Wherein, the base 600 is detachably connected with the housing 200. Referring to fig. 7, four clamping convex columns 610 are distributed on the upper surface of the base 600 along the circumferential direction of the edge at intervals, and the four clamping convex columns 610 are spaced by 90 degrees. Referring to fig. 8, four slots 250 are circumferentially spaced on the inner wall of the housing near the lower end, and when the base and the housing 200 rotate relatively, the latching protrusion 610 can be latched into the slot 250 or disengaged from the slot 250, so that the housing 200 of the base is mounted on the base or disengaged from the base.

Referring to fig. 1 and 2, the present invention is assembled as follows: the PCB board and the silicone pad 300 are first locked to the bottom of the connection board 220 of the housing 200 with screws 800. The four hook alignment hooks 120 of the button cover 100 are aligned with and inserted into the four hook holes 240, respectively, and the pressing post 110 of the button cover 100 is also inserted into the central hole 230 at the same time. Thereafter, the base 600 is rotatably mounted to the bottom end of the housing 200 with the sealing ring 700 interposed between the base and the housing 200. Finally, the base 600 is attached to the wall surface by the double-sided adhesive tape 700, and the installation is completed.

Referring to fig. 2, since only one mechanical key is disposed in the middle of the button cover 100, 4 hook points are disposed on the outer side of the button cover, and a silica gel pad with good deformation is disposed between the button cover and the PCB, the switch 410 of the PCB can be easily triggered by pressing the button cover at any position (middle or outer position) by hand, so as to realize corresponding functions.

The position of the button cover close to the edge is pressed by a hand, the buckle on the side is pressed downwards, the hook on the other side is stably hooked, the mechanical key and the hook point on the side move downwards until the switch moves to the maximum stroke (triggers the corresponding function) to stop, and the force value of the position of the hook point is smaller than that of the middle position by a whole half according to the lever principle.

In the present embodiment, the key is circular, and in other embodiments, the key can be designed in other shapes.

The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the utility model, which is defined by the appended claims and their equivalents.
