Description

Multiple road button

The utility model relates to button, refers in particular to a kind of button on the keyboard.

Button on the existing key panel 10a as shown in Figure 1, it is a hollow, rectangular body that a plurality of keyseat 11a are arranged, each keyseat 11a has a keycap 12a, one hollow, rectangular key post 13a is arranged at keycap 12a bottom, and key post 13a four corners are provided with cylinder 14a, and two sides are provided with shell fragment 15a, make key post 13a elasticity be incorporated into keyseat 11a, cylinder 14a can reduce resistance, key post 13a can be back and forth and vertical ground motion in keyseat 11a, make the elasticity of key post 13a below touch optionally starting switch of body 16a.

But this keyseat 13a is difficult for cooperating with keyseat 11a, is difficult to accurately be positioned keyseat 11a, owing to cooperate the location to be difficult for, causes the assembling trouble, uses inconvenience.

The purpose of this utility model provides a kind of assembling, multiple road button easy to use.

The purpose of this utility model is achieved in that multiple road button, it comprises keyseat, keycap, it is characterized in that: the keyseat that is formed on the key panel is a hollow cylindrical body, and inwall is provided with the two relative fixing guiding convex bodys of protrusion, has the inclined-plane on the guiding convex body; But the keycap bottom is provided with the hollow cylindrical body key post of a to-and-fro movement in keyseat, the key column outer wall is provided with corresponding two guide rails of fixedly guiding convex body with keyseat, guide rail Lower Half two sides are provided with the space, and two guide rails have elasticity and the interior lower end of guide rail respectively is provided with an elasticity convex body; The key post of keycap is matched with in the keyseat, and the two fixing guiding convex bodys of keyseat inwall and the guide rail of key column outer wall cooperatively interact.

Above-mentioned design has reached assembling, good result easy to use.

Below by drawings and Examples the utility model is described further again.

Fig. 1 has the button perspective exploded view now;

Fig. 2 the utility model perspective exploded view;

Fig. 3 the utility model plan cross-section synoptic diagram;

Fig. 4 the utility model schematic top plan view;

Shown in Fig. 2-4: the utility model is made of a keyseat 10 and a keycap 20, wherein keyseat 10 is formed on the key panel 11, this keyseat 10 is a hollow circular body, and keyseat 10 inwalls are provided with relative two fixing guiding convex bodys 12 of protrusion, and this is fixed on guiding convex body 12 and has inclined-plane 13.Keyseat 10 inwalls can be provided with at least one guide groove 14 in addition, are provided with a guide groove 14 as shown in the figure, and the key column outer wall is provided with corresponding sliver 26.

Keyseat 10 respectively is combined with a keycap 20, and keycap 20 bottoms are provided with a hollow circular body key post 21, and the motion that the key post 21 of keycap 20 can be reciprocal is in keyseat 10.Key post 21 outer walls are provided with fixedly guiding convex body 12 corresponding two guide rails 22 with keyseat 10, guide rail 22 Lower Halves two sides are provided with the space 23 that the lower end is opening, so that two guide rails, 22 Lower Halves can be omited tool elasticity, lower ends respectively are provided with an elasticity convex body 24 in two guide rails 22, on this elasticity convex body 24 and have a cambered surface 25.Key post 21 outer walls can be provided with the guide groove 14 corresponding slivers 26 with keyseat 10 in addition, in order to prevent the mistake dress.

The key post 21 of keycap 20 is matched with in the keyseat 10, and makes two fixing guiding convex bodys 12 of keyseat 10 inwalls and two guide rails 22 of key post 21 outer walls cooperatively interact, and the vertical movement that key post 21 can be reciprocal is in keyseat 10.When pushing keycap 20 key post 21 is moved downward vertically, place the FPC 40 on the base plate 50 below the portion that presses 31 of the elasticity shake-up body 30 below can making presses, make switch do the ON action; When decontroling keycap 10 pressure, mat elasticity is touched body 30 elastic force, make the portion of pressing 31 leave FPC 40, make switch do the OFF action, so that this elasticity is touched optionally starting switch of body 30, touching body 30 and FPC 40 generally is same as known techniques because of this elasticity, is not the category that the utility model is applied for a patent, so do not give detailed description.

Because keyseat 10 and key post 21 are cylinder, can centralized positioning, and keyseat 10 and key post 21 can utilize the cooperation of fixing guiding convex body 12 and guide rail 22, stablize the vertical movement of guide keys post 21, in addition can be by the cooperation of the sliver 26 of the guide groove 14 of keyseat 10 and key post 21, the stability of promoting 21 vertical movements of key post.Owing to have the inclined-plane 13 of guide function on the fixedly guiding convex body 12 of keyseat 10, and two guide rails 22 of keycap 20 and elasticity convex body 12 can be matched with in the guide rail 22 of key post 21 easily, and be comparatively easily simple in the assembling.

During use, when key post 21 moves upward, the elasticity convex body 24 of this key post 21 is subjected to the restriction of the fixing guiding of keyseat 10 inwalls convex body 12, available to prevent that key post 21 from deviating from keyseat 10, and has cambered surface 25 on the elasticity convex body 24, the effect of the elasticity that mat itself has and cambered surface 25 bufferings makes elasticity convex body 24 guide contacting that convex body 12 can be appropriate with fixing, and can reduce the noise that is produced.

With guide rail 22 in conjunction with flexible design, this guide rail 22 has guide keys post 21 and stablizes outside the effect of vertical movement, and can utilize the fixedly guiding convex body 12 flexible conflicts of guide rail 22 and keyseat 10, what make that key post 21 can be suitable is positioned keyseat 10, and it is excessive and cause the card key not have friction force, or friction force is too small and cause loosening phenomenon to take place, comparatively convenient in the use, and it cooperates the location easily, and is comparatively convenient in the assembling, and production cost is significantly reduced.
