Embodiment
Understand for the technical characterictic to utility model, object and effect have more clearly, now contrast brief description of the drawings embodiment of the present utility model, in each figure, identical label represents the identical or structural similarity of structure but the identical parts of function.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the execution mode that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technical scheme of advantage.
For making drawing succinct, in each figure, only schematically show the part relevant to the utility model, they do not represent its practical structures as product.In addition, for making drawing succinctly be convenient to understand, in some figure, there are the parts of same structure or function, only schematically illustrated one of them, or only marked one of them.
In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".In this article, " on ", D score, 'fornt', 'back', " left side ", " right side " etc. be only for representing the position relationship between relevant portion, and non-limiting their absolute position.
Fig. 1 is in order to illustrate a kind of exemplary embodiment of rubber key, and as shown in Figure 1, rubber key 10 comprises the press section that can Gong press 12, and a fixed part 14 for fixing rubber key 10, comprises an elasticity muscle 142 on the sidewall of fixed part 14.
As shown in Figure 2, if press the press section 12 of rubber key 10, make it move to position shown in dotted line in figure along the direction of pressing shown in arrow, in this process, elasticity muscle 142 on fixed part 14 also can move to the elasticity muscle position shown in dotted line, now, there is strain in elasticity muscle 142, and it can produce elastic restoring force, stop pressing behind press section 12, the elastic restoring force of elasticity muscle 142 can help rubber key 10 returns, helps position shown in dotted line from figure, press section 12 to be returned to solid line position, to avoid the phenomenon of card key.The rubber key with elasticity muscle is easily manufactured production, without increasing larger production cost.
About the stressing conditions of rubber key, as drawn any the stressing conditions on elasticity muscle 142 in Fig. 2, on this aspect because strain can produce along the elastic restoring force F of this tangential direction, this elastic restoring force F has along pressing the component f that direction N is contrary, and the elastic restoring force of elasticity muscle 142 can help rubber key 10 returns along pressing the component that direction N is contrary.
