Abstract
The utility model discloses a mechanical calling button which comprises an upper button cover and a lower button cover, wherein the upper button cover is matched with the lower button cover, the upper button cover is formed by a frame and an upper cover body nested in the frame, the lower button cover is provided with a wavy spring, and the upper cover body is in elastic connection with the lower button cover through the wavy spring. According to the mechanical calling button, the upper button cover is in elastic connection with the lower button cover through the wavy spring. The mechanical calling button can be made thinner with no need for a long stroke of an existing spring. Meanwhile, accuracy of the button is improved.
Description
Technical field
The utility model relates to a kind of calling mechanical button, belongs to elevator field.
Background technology
Calling mechanical button is called and is called out elevator to designated floor for passenger, is the vitals of controlling elevator operation and man-machine interaction.Calling mechanical button is generally arranged on circuit card, and can be along moving up and down perpendicular to circuit card direction.Calling mechanical button comprises button upper cover and button lower cover, and a spring of the each installation of four corners of button upper and lower covers, connects the elasticity that forms above-below direction between button upper and lower covers.When cover external force on button presses down, four spring generation deformation produce elastic force upwards.After being positioned at the contact of button upper cover lower surface and touching the switch on circuit card, external force removes, and button upper cover resets under resilient force.Because the volume of spring is larger, what make that whole calling mechanical button is difficult to do is thinner.
Meanwhile, existing calling mechanical button arranges the connection mode of four springs at four jiaos of places, button often can occur and contact not good problem with switch in contact afterwards.The position that for example user presses is during near some springs, and the deformation of this spring is larger, and other three spring deformations are little.Cause like this contact to be difficult to be pressed into the switch on circuit card.
Utility model content
Utility model object: the utility model proposes a kind of calling mechanical button, its thickness is thinner, and button accuracy is also higher simultaneously.
Technical scheme: the technical solution adopted in the utility model is a kind of calling mechanical button, comprise button upper cover and the button lower cover of mutual adaptation, described button upper cover is made up of framework and the upper cover body being nested in framework, under described button, be covered with wavy spring, between upper cover body and button lower cover, form elasticity by this wavy spring and be connected.
As a kind of improvement of the present utility model, described upper cover body lower surface is provided with the silica gel contact corresponding with the center hole of wavy spring.
As of the present utility model another improve, described upper cover body be each side provided with two projections.
Further improve as of the present utility model, described button lower cover be each side provided with one with the suitable guide groove of described projection.Under described button, be covered with the rib that stretches into guide groove.
Beneficial effect: the present invention, by wavy spring, forms elasticity and is connected between button upper cover and button lower cover.The stroke that this button is grown without existing spring, what make to call mechanical button to do is thinner.Also improved the accuracy of button simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
As shown in Figure 1, button upper cover is made up of framework 8 and the upper cover body 1 being nested in framework 8, and upper cover body 1 can move up and down in framework 8.Wherein upper cover body 1 be each side provided with two projections 5, the upper surface of upper cover body 1 also scribbles sign.The left and right sides of button lower cover 2 is respectively equipped with a guide groove 4.Button upper cover and button lower cover 2 are to be all made up of PC plastics, utilize their elastic deformations own, and projection 5 is embedded in guide groove 4.Mutual adaptation between projection 5 and guide groove 4, in order to make button upper cover do front and back parallel sliding (as shown in Fig. 1 arrow) along guide groove 4, also links together button upper cover and button lower cover 2 on the one hand on the other hand.This parallel sliding function of button upper cover has huge effect in actual installation.When installation, button upper cover is to be nested in the through hole of panel, and described erecting of panel, on circuit card 6, plays the effect of protective circuit plate.And due to reasons such as production tolerances, the through hole of panel and button upper cover can not be just adaptive, cause the upper cover body 1 after installing to contact with the front or rear edge of panel through hole, produce larger damping.Therefore in this case, the button upper cover in the present embodiment is by the parallel sliding of front and back, adjusts in time the distance between panel through hole front and rear side edge, make damping less use more convenient.
The surface of button lower cover 2 is also provided with the rib 7 that stretches into guide groove 4, and each guide groove 4 is separated into three sections by two root bars 7.This segmentation is restricted the sliding stroke of two projections 5 of framework 8 each side, is unlikely to sliding distance excessive.
Different from existing calling mechanical button, the button of the present embodiment does not use spring at four summits place of button lower cover 2.But a wavy spring 3 is set in the center of button lower cover 2, replace traditional spring.Wavy spring 3 is circular, along the fluctuating that circumferentially presents sine wave shape of annulus.Upper cover body 1 is under pressed by external force, and the silica gel contact (not shown) of its lower surface is also to the switch on lower compression circuit card 6.In this process, wavy spring 3 is owing to deformation occurring all the time to 1 one of upper cover bodies elastic force upwards.In the time buttoning to end external force and remove, this elastic force upwards resets upper cover body 1.Utilize wavy spring 3 its shorter springing stroke, effectively reduce the thickness of whole calling mechanical button.
Because wavy spring 3 is arranged on the center of button lower cover 2, even user key-press position deviation center, the deformation difference of wavy spring 3 in all directions is also little, the silica gel contact that is positioned at button lower cover 2 lower surfaces can be approached with the state parallel with circuit card 6, accurately press the switch on circuit card 6.
Claims (5)
