Description

The improvement button

The utility model relates to button.

Patents such as the button of existing scissor structure such as notification number 237991,314250,319438,322178, its keycap is arranged on the two cross-shaped supports, keycap is moved up and down by the guiding of two supports, make the elasticity shake-up body under it press or leave wiring board, become ON or OFF action, sense of touch is preferable, can not rock, be suitable for ultra-thin keyboard, but cost height not only, cause and still have inadequately disappearance easily in the use.

The purpose of this utility model provides a kind of improvement button that uses reliable convenience, reduces cost.

The purpose of this utility model is achieved in that the improvement button, its keyseat is provided with an assembly hole, one key post is arranged at the keycap bottom, and activity is matched with in this assembly hole, it is characterized in that: this keyseat outside and keycap bottom both one of be provided with at least one and lead rib, both are provided with at least one corresponding breach, and lead rib and be matched with in the breach, therebetween and form the contact of at least one line.

Above-mentioned design makes that keycap only can be done straight to go up, the activity under straight, and can not rock, and reaches reliably effect easily of use.

Explain again with accompanying drawing, embodiment below.

Fig. 1 the utility model three-dimensional combination figure;

Fig. 2 the utility model three-dimensional exploded view;

Fig. 3 the utility model transverse sectional view;

Fig. 4 the utility model longitudinal sectional view;

Fig. 5 the utility model push action figure;

Another embodiment three-dimensional exploded view of Fig. 6 the utility model;

Another embodiment transverse sectional view of Fig. 7 the utility model.

Shown in Fig. 1-5: the utility model keyseat 10 is provided with an assembly hole 12, one key post 21 is arranged at keycap 20 bottoms, and activity is matched with in this assembly hole 12, it is characterized in that: these keyseat 10 outsides and keycap 20 bottoms both one of be provided with at least one and lead rib 22, both are provided with at least one corresponding breach 14, and lead rib 22 and be matched with in the breach 14, therebetween and form at least one line contact.Wherein, these keyseat 10 outsides are provided with location notch 13, these keycap 20 bottoms convex with reference column 24, and be matched with in the location notch 13, the keyseat 10 of hollow square frame body is formed on the keyseat substrate 11, breach 14 is established four, and the opening shape is formed on its sidewall and top, and is located at four jiaos in keyseat 10 outsides or other positions; Keycap 20 bottoms are provided with in addition leads rib 22 and corresponding with the breach 14 of keyseat 10, and present embodiment is provided with four and leads rib 22, and wherein, this is led rib 22 and is en plaque.The front end shape can be done suitable variation, the rear end respectively is connected with a curved reinforced ribs 23, this button is located at elasticity and is touched body 30, Flexible Printed Circuit 40 and base plate 50 tops, when pushing, press portion 31, make it do ON, OFF action, breach 14 and lead cooperatively interacting of rib 22, cause concavo-convex guiding mechanism, between can form the contact of many lines, only can do the activity of single direction along breach 14 in order to restriction.

Shown in Fig. 6,7: breach of the present utility model and lead the position is set exchanges of rib 22, at least establish one in keyseat 10 outsides and lead rib 15, present embodiment is four, be convexly equipped with at least one guide pillar 25 in strong cap 20 bottoms in addition, and respectively establish a breach 26 and to lead rib 15 corresponding, breach 26 sidewalls and bottom also form the opening shape, and effect is identical.But button does not adopt scissor structure, greatly reduces manufacturing cost.
