Embodiment
The utility model provides a kind of press-key structure that is used for electronic installation, with specific embodiment execution mode of the present utility model is described below.
Referring to Fig. 3, be the utility model embodiment press-key structure button three-dimensional view.Button 310 comprises a keying body 301, be arranged on first cylindrical boss 302 and second cylindrical boss 303 at keying body 301 back sides, be arranged on first support component 304 between two boss, described first support component 304 comprise an opening angle be 50 ° cross section for circular elastic cylinder connected in star 305. referring to Fig. 4, be the utility model press-key structure cross section view, comprise second support component 401 on the face-piece, described second support component 401 comprises the cylindrical body supports post 402 that matches with elastic cylinder connected in star 305, described cylindrical body supports is lived cantilever and is installed on second support component 401, described cylinder shape groove 305 and cylindrical body supports post 402 hinged formation hinge arrangements, it is the lever construction of fulcrum that described first cylindrical boss 302 and second cylindrical boss 303 form with the hinge arrangement with hinge arrangement.
During the assembling press-key structure, the opening of the elastic cylinder connected in star 305 on first support component 304 on the button is pressed to the cylinder 402 that matches with cylinder shape groove on second support component 401, making elastic cylinder connected in star 305 form hinge with cylinder 402 cooperates, like this, first cylindrical boss 302 and second cylindrical boss 303 can press the contact switch of electronic installation respectively.
In use, one end at first cylindrical boss, 302 places by the pressing keys main body, first cylindrical boss 302 presses the contact switch on the electronic installation, switch closure, this moment, second cylindrical boss 303 was away from the contact switch on the electronic installation, the open elastic switch that is in contact described in the present invention on the electronic installation, therefore after the first cylinder boss 302 pressed contact switch on the electronic installation, the elasticity of contact switch itself can make first cylindrical boss 302 reset; Second cylindrical boss 303 is identical with the working method of first cylindrical boss 302.
Herein, the contact switch of described electronic installation is the contact switch that is used on the electronic installation well known to those skilled in the art, and having little elastic force can automatically reset.
In order to reach the purpose of this utility model, described hinge arrangement is used to connect button and face-piece and makes button do rotatablely moving of certain angle with respect to face-piece, it is the lever construction of fulcrum that two boss and hinge arrangement form with the hinge arrangement, like this when the position of positive two boss of pressing keys body, button rotatablely moves with respect to face-piece, can make two boss press contact switch on the electronic installation, the elastic force by contact switch itself reaches the purpose that button is resetted then.Described hinge arrangement is a hinge arrangement well known to those skilled in the art.Design of the present utility model has saved the design of location hole, support rod etc., uses hinge arrangement as positioner, has therefore saved the shared space of button greatly.In order to reach convenient purpose of installing, the utility model further is provided with the elasticity groove that the cross section is the opening of circular arc on first support component, circular arc convex body with the elasticity groove surface contact matching of opening is set on second support component then, elasticity groove and circular arc convex body form hinge arrangement, owing to use the elasticity groove, therefore only need when mounted to press down button from the front of face-piece, the elasticity groove is cooperated with the circular arc convex body, can realize the location of button, simplify mounting process greatly, improved operating efficiency.In addition, also can on second support component, the elasticity groove be set and the circular arc convex body is set on first support component, can reach the purpose of this utility model equally.Cross section described in the utility model is that the elasticity groove of circular arc can be truncated cone-shaped, also can be for cylindrical, and perhaps the combination of multistage round platform and/or cylinder is not limited to this, and arc cam is the shape that matches with the elasticity groove.
In order better to realize the location of button and face-piece, the opening angle of elastic opening groove can be 5 °～100 °, preferably, opening angle is 20 °～80 °, preferred, opening angle is 40 °～60 °, selects optimum opening angle, not only convenient installation the, and more stable connection button and face-piece.
Herein, two boss on the keying body back side are used to press contact switch on the electronic installation as pressing post, therefore the cross section can be round, square or other known form, for the ease of processing, the cross section can be for round, can also further be provided with to make on face-piece to press the position, hole that post passes through.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
