Detailed description of the invention

Fig. 1 is a kind of perspective view of the explosion of no one preferred embodiment of spring butterfly structure elevator button of the utility model

Specific embodiment

Below in conjunction with drawings and examples, the present invention will be further described in detail.It should be appreciated that this place is retouched The specific embodiment stated only to explain the utility model, is not used to limit the utility model.

It is an a kind of preferred embodiment of no spring butterfly structure elevator button of the utility model please together referring to Fig. 1, packet Button word slice 1, word slice pedestal 2, butterfly driving member 3, shell 4, PCBA 5, screw 6 and fixed card buckle 7 are included, main feature exists In: the button word slice 1 is bonded on the word slice pedestal 2；The butterfly driving member 3 is assemblied under the word slice pedestal 2；Institute It states word slice pedestal 2 and passes through four snap-fitteds on the shell 4；The PCBA 5 is fixed under the shell 4 by screw 6 Portion；The button word slice 1, word slice pedestal 2, butterfly driving member 3, shell 4, PCBA 5, screw 6 form an assembly；It is described Assembly is fixed on elevator by the fixed card buckle 7；Structure and the word slice bottom by the butterfly driving member 3 itself Assembly relation between seat 2 and shell 4, Lai Shixian button pop up reset function after pressing.

Further, the position that the joining place of the critical component of the butterfly driving member 3 namely folds every time is single The original part of one component composition, tests the durability of this component very much, so to use the material of toughness, generally uses plastics POM or nylon material.

Further, plastics POM, i.e. acetal resin, polyformaldehyde are a kind of without side chain, high density, high crystalline Linear polymer.By the difference of chemical structure in its strand, acefal homopolymer and two kinds of copolymerized methanal can be divided into.The weight of the two Distinguishing is: acefal homopolymer density, crystallinity, fusing point are all high, but thermal stability is poor, processing temperature narrow range (about 10 DEG C), right Ph stability is slightly lower；And copolymerized methanal density, crystallinity, fusing point, intensity are all lower, but thermal stability is good, are not easily decomposed, and add Work temperature range is wide (about 50 DEG C), preferable to ph stability.It is the engineering plastics with excellent comprehensive performance.Have good Physics, mechanically and chemically performance especially have very high mechanical strength, rigidity and very high fatigue strength.

Further, the button word slice 1 passes through glue or tape-stripping on the word slice pedestal 2,1 energy of button word slice Enough it is replaced update.The butterfly driving member 3 is assemblied under the word slice pedestal 2 by buckle or screw.

Further, the PCBA 5 is fixed to 4 lower part of shell by the fixed material such as screw.

Further, the upper surface of the button word slice 1 is printed with corresponding floor number.

Further, the upper surface of the button word slice 1 is provided with blind person's pillar.

Further, the outer surface of the button word slice 1 and word slice pedestal 2 is through frosted landscaping treatment.

Further, selected floor information is transmitted to external elevator system controller by the PCBA 5.

Further, the PCBA 5 has circuit board, using power supply power supply in elevator cable line.

The working principle of the present embodiment is as follows: when in use, after 1 stress of button word slice is pressed, dynamics passes to butterfly The two sides of formula driving member 3, the bottom decline of butterfly driving member 3 touch the contact of 5 top PCBA, and the dynamics of button word slice 1 is removed When pin, butterfly driving member 3 resets, the contact separation of 5 top of 3 bottom of butterfly driving member and PCBA.

The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then It all should be in the protection scope of the appended claims for the utility model.
