Specific implementation mode

The utility model is described in further detail below in conjunction with specific embodiment and attached drawing.

Embodiment one：

As shown in Figure 1, Figure 2 and Figure 3, a kind of mute structure of mechanical switch, including pedestal 10 and with pedestal 10 fasten Upper cover 20, pedestal 10 and the fastening of upper cover 20 form cavity, and button 30, switch terminal 40 and the first spring are equipped in cavity 50, switch terminal 40 is mounted on pedestal 10, and 30 lower end of button is provided with guide post 33, and pedestal 10 is provided with corresponding with guide post 33 Mounting post 11 is provided with counterbore corresponding with guide post 33 12 in mounting post 11, and the first spring 50 is set in mounting post 11, button 30 are moved up and down by the first spring 50 in cavity, and guide post 33 is slided along counterbore 12 so that button 30 is smoothly in cavity It moves up and down, and links with switch terminal 40, the function of switch is realized with this.

The sound sent out when pressing or pop up for reduction button down, fin 31 is both provided in 30 both sides of button, It is close to 30 side wall of button in fin 31 and is fixed with the first ring-shaped article 60, which is elastic component, the first ring-shaped article 60 Upper and lower ends are higher than 30 upper and lower end face of button, and the upper and lower ends of the first ring-shaped article 60 buffer 30 lower end of button when button 30 presses The collision of buffering button 30 upper end and upper cover 20 with pedestal or when bouncing.In this way, popping up or pressing down in button 30 When, due to there is the buffering of the first ring-shaped article 60 so that button 30 will not collide with upper cover 20 and pedestal 10, would not also send out Go out sound.First ring-shaped article 60 is made of silica gel material.

Wherein, fin 31 is strip setting up and down, and fin both sides are provided with positive stop lug boss 32, positive stop lug boss 32 with it is convex There is spacing between rib 31, the first ring-shaped article 60 is placed on fin 31 and both sides are stuck between positive stop lug boss 32 and fin 31, from And further consolidate the first ring-shaped article 60 of assembling.

Embodiment two：

As shown in Figure 4, Figure 5 and Figure 6, the present embodiment is the improvement done on the basis of embodiment one, difference lies in：

In the present embodiment, button 30 is divided into two components, and two components can be connected by way of riveting, in the present embodiment Beam barrel 70 and second spring 71 are increased, 70 top of beam barrel is inserted into 71 one end of second spring, and the other end is abutted with button 30.Beam barrel 70 one end are inserted between two components of button 30, and button 30 can drive beam barrel 70 to move up and down to real by the first spring 50 Now switch the effect being turned on or off.

It is appreciated that the length due to mounting post is different, may cause when fin 35 is not collided with pedestal 10, mounting post 11 first collide with 30 bottom of button, to generate sound.To avoid the above situation, therefore, one is equipped in the bottom of button 30 Elastic second ring-shaped article 13, the second ring-shaped article 13 are located at 11 top of mounting post, and the second ring-shaped article 13 can also be set in beam barrel 70 On.In this way, when button 30 presses, the collision between button 30 and mounting post 11 is buffered, reduces noise.Second ring-shaped article 13 is silicon Glue material is made.

Embodiment three：

As shown in Figure 7, Figure 8 and Figure 9, the present embodiment is the improvement done on the basis of embodiment one and embodiment two, area It is not：

Further include the resilient snubber 14 between two lower ends for being padded on fin 35 and pedestal 10 in the present embodiment, it should Bolster 14 is mounted on the pedestal 10 immediately below fin 31, for increasing buffering thickness.

It is appreciated that also due to the length difference of mounting post, may cause when fin 35 is not collided with pedestal 10, pacify It fills column 11 first to collide with 30 bottom of button, to generate sound.Bolster 14 is located at 31 lower section of fin, can increase buffering thickness, Then the lower end of fin 31 or the lower end of the first ring-shaped article 60 are first collided with bolster 14.Bolster 14 is made of silica gel material.

Although the description combination embodiments above to the utility model carries out, it is familiar with the art Personnel can carry out many replacements according to above-mentioned content, modifications and variations, be obvious.Therefore, all such It substitutes, improve and changes and be included in the spirit and scope of appended claims.
