The beneficial effects of the utility model are：

The power that button resets is provided by the deformation of floating piece, can meet that press-key structure in tight space installs will Ask, simple structure, it is easy to accomplish.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the schematic perspective view of the utility model press-key structure one embodiment；

Fig. 2 is the close-up schematic view of the utility model POS sectional view.

Specific embodiment

The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that not conflicting In the case of, the feature in embodiment and embodiment in the application can be mutually combined.

It should be noted that unless otherwise specified, when a certain feature is referred to as " fixation ", " connection " in another feature, It can directly fix, be connected in another feature, it is also possible to fix indirectly, be connected in another feature.Additionally, this The description such as upper and lower, left and right used in utility model is only the phase relative to each part of the utility model in accompanying drawing For mutual position relationship.

Additionally, unless otherwise defined, the technology of all of technologies and scientific terms used here by the article and the art The implication that personnel are generally understood that is identical.Term used in the description is intended merely to describe specific embodiment herein, without It is to limit the present invention.Term as used herein " and/or " include the arbitrary of one or more related Listed Items Combination.

Reference picture 1, shows the decomposing schematic representation of the utility model press-key structure one embodiment, and the utility model is fitted As shown in FIG., button itself is more elongated for scene, and the area stenosis of button are accommodated in POS, common by bond Structure is difficult to ensure that stability during pressing, based on this, the utility model discloses a kind of press-key structure, including button 100 and band There is the substrate 200 of contact 210, also including the elastic film 300 between button 100 and substrate 200.

Button 100 includes keycap 110, and the lower section of keycap 110 is extended with first support bar 120 and second support bar 130, the One support bar 120 is used to triggering contact, and the second supporting plate 130 is then used to installing fixed button 100, and with following Thin Elastics Film is supported to provide the power of button reset, and wherein second support bar 130 is at least at two, is preferably symmetrically set in first support bar 120 both sides are with force balance.

Correspondence first support bar 120 is provided with a through hole 301 on elastic film 300, and correspondence second support bar 130 is provided with and can go up The floating piece 302 of lower floating, the area of floating piece 302 should be more than the end of second support bar 130.Wherein first support bar 120 then support through the top that the correspondence of substrate 200 contact is located at after through hole 301, second support bar 130 with floating piece 302, when pressing When key 100 is moved downward, first support bar triggering contact, floating piece 302 is deformed by the compressing of second support bar 130, led to The deformation for crossing floating piece 302 provides the power that button resets, and can meet the requirement that press-key structure is installed in tight space, this reality Silica gel thin film is preferably with new middle elastic film.

Preferably, the top of floating piece 302 is all provided with fluted with lower section, and the groove can increase the elasticity of floating piece 302, The bottom of second support bar 130 can be snapped within groove simultaneously, it is to avoid second support bar 130 departs from floating piece.

The bottom of second support bar 130 is extended with horizontal snap fit 131 in the side for being different from first support bar 120, should The one side of snap fit 131 can coordinate fixed button with the shell in POS, while can also increase second support bar 130 and float Contact area between piece 302, increases stability during pressing.

Additionally, circumferentially arranged with a plurality of gib block 121 on the circumference of first support bar 120, specifically into cross distribution, Gib block 121 along first support bar 120 the end for axially extending to first support bar 120, additionally, first support bar 120 Bottom has a circular arc termination.

The invention also discloses a kind of POS, reference picture 2 shows the partial schematic diagram of POS sectional view, POS Machine includes shell 400 and above-mentioned press-key structure, and first, second support bar of correspondence is provided with via on shell 400, first, the Two support bars are plugged in corresponding via, and the gib block 121 in first support bar 120 is oriented to by the hole wall of via, it is to avoid press Key occurs crooked when moving up and down；Snap fit 131 in second support bar 130 can be abutted with the bottom of corresponding via, prevent by Key is deviate from from via.

Additionally, as can be seen from the figure first support bar 120 is located at the top of contact 210, second support bar 130 is located at floating The top of moving plate 302, floating piece 302 is all provided with the fluted elasticity to increase floating piece 302 up and down.

Above is preferable implementation of the present utility model is illustrated, but the invention is not limited to the reality Example is applied, those of ordinary skill in the art can also make a variety of equivalent variations on the premise of without prejudice to the utility model spirit Or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
