Embodiment
The invention provides a kind of shockproof structure of mould height indicator, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1 to Fig. 4, it is the structural representation of the shockproof structure embodiment one of mould height indicator provided by the invention, comprise a housing 7, an opening and the panel 1 for closing described opening is provided with in described housing 7 side, a display screen 3 is also provided with at opening part, described shockproof structure also comprises the back up pad 2 be arranged between panel 1 and opening, and described display screen 3 embeds in described back up pad 2, and described panel 1 is fixed on housing 7 by described back up pad 2.
In the present embodiment; by arranging a back up pad 2 between panel 1 and housing 7 opening; and be embedded in back up pad 2 due to display screen 3, so display screen 3 can be protected to rock from pressing machine fierceness the infringement brought, avoid the infringement that display screen display is unstable and rock circuit board.
In order to further protect display screen, also can the shockproof cotton of sheathed display screen in the surrounding of described display screen 3, to play the effect of damping vibration.
Also connection one circuit board 4 at the back side of described display screen 3, described circuit board 4 connection one power supplier.Panel 1 and described housing 7 form an enclosure space, and circuit board 4, back up pad 2, display screen 3 and power supplier are arranged in described enclosure space.
Specifically, be hollow structure at the middle part of described back up pad 2, respectively to extend internally out a liner plate in the surrounding of this hollow structure, display screen 3 described like this can be embedded in the square structure of these four liner plates formation, and can shockproof effect be played, these four liner plates and back up pad 2 are wholely set, and its structure formed is more stable, can avoid display screen 3 rocking up and down.
In addition, also shockproof insulating gel can be filled between display screen 3 and liner plate, further to improve shockproof effect.Also shockproof insulating gel is filled between back up pad 3 and circuit board 4, to improve the shockproof properties of circuit board 4, because strong motion may cause the sealing-off of circuit board and sensor weld, the unstable operation of electronic component, the jitter that sensor vibration produces or error signal etc., apply shockproof insulating gel on the circuit board 4, apply this shockproof insulating gel, such as silica gel, can improve circuit board and sensor, and the shockproof effect of display screen.
Power supplier is specifically as follows external power supply, and certainly, it is optional, also can select battery.Display screen 3 can be touch-screen or LCDs or digitron display screen etc.Preferably, the vibrations in order to avoid punch press damage the display screen 3(of glass as touch-screen or LCDs), display screen 3 is preferably digitron display screen.Described display screen preferably integrally shields structure, one screen structure of the present invention, its essence be by required multiple LED display unit set in an one-piece construction, such as by the method for injection mo(u)lding by multiple LED display unit set in an overall plastic cement structure, its pin of such structure is less, and cost is lower, inner structure is more succinct, take up room less, can failure rate be reduced, simultaneously shockproof effect and insulation effect also better.
Preferably, in order to strengthen the shockproof effect of battery, be arranged with a battery shockproof cover outside described battery, described battery shockproof cover has wrapped up the annular profile of battery.
Described housing 7 opening part is provided with an installed surface, and described back up pad 2 is arranged on installed surface by screw 16.Also be provided with erection column in the corner of described back up pad 2, by described erection column, circuit board locked on the supporting plate, to facilitate test and assembling.
Specifically, recessed step is formed at the rims place of housing 7; Described back up pad 2 is fitted on described step; Described panel is glue film, and it corresponds to part of display screen and is set to transparence, and display screen 3 light-transmitting panel 1 is shown, and described panel 1 is fitted described back up pad 2; On described back up pad 2 and installed surface, all correspondence is provided with threaded hole, by mounting screw 16 in described back up pad 2 and installed surface, described back up pad 2 is fixed on the installed surface of described housing 7 opening part.Such structure can make back up pad 2 firmly be embedded on installed surface, and panel 1 flushes with housing 7 edge of opening place after installation is complete, form an one-piece construction, because the gap between step and back up pad 2 is very little, such back up pad 2 up and down four direction is all stuck, to such an extent as to all can not be subjected to displacement under macroseism, so improve its shockproof properties.
Also to being outside equipped with the transmission shaft 9 that extends (opening reverse direction) outside housing 7 in described housing 7, at least one bearing sheathed on described transmission shaft 9, such as, arrange the bearing 11 at two intervals.Described transmission shaft 9 extends end vertical grafting one trundle 10 outside housing 7, except latch structure is set, as shown in Figure 3, also can by transmission shaft 17(9) part of extending outside housing 7 arranges a shockproof flexible axle 18, an also pluggable trundle 10, to improve shockproof effect.The described end of transmission shaft 9 in housing 7 is provided with permanent magnet 14.Described permanent magnet 14, its be with the magnetic position sensor that arranges on circuit board 4 with the use of.Specifically, described permanent magnet 14 is connected to transmission shaft 9 by gear structure, described gear structure comprises driving gear 12 and follower gear 5, described driving gear 12 is sleeved on described transmission shaft 9, described permanent magnet 14 is arranged on follower gear 5, and described driving gear 12 engages with described follower gear 5.Described circuit board 4 is provided with a fixed mount 6, and this fixed mount 6 is for supporting follower gear 5.A stationary shaft is provided with in the middle part of described follower gear 5, described stationary shaft is connected with described fixed mount 6, the radial direction realizing follower gear 5 is like this fixed, follower gear 5 can be rotated around described stationary shaft, stationary shaft is wherein for being fixedly installed, and by screw 13 axial restraint between described follower gear 5 and stationary shaft, stationary shaft is fixedly installed, namely follower gear 5 can rotate around stationary shaft, and driving gear 12 and axle 9 are then wringing fits.
Described circuit board 4 is arranged with transmission shaft 9 empty avoiding, as shown in Figure 5, the part that circuit board 4 corresponds to transmission shaft 9 is set to empty avoiding, such as adopt the mode shifted to install or the part hollow out corresponding to transmission shaft 9 on the circuit board 4, the object of setting like this is when preventing transmission shaft 9 from breaking down, and breaks through the restriction of bearing and housing 7, when being flushed to housing 7 inside, damage circuit board 4, avoid the serious problems such as circuit board 4 short circuit electric leakage.Part simultaneously in this housing 7 need reserve space when transmission shaft 9 is punched in housing 7, makes transmission shaft 9 can not wash out circuit board and sensor.
The position oil sealing 8 contacted with housing 7 at described axle 9 seals, and to play grease proofing effect, it can prevent the pollution from oil outer, water and dust.Axle needs lubrication in transmission process simultaneously, and oil sealing also can play the generation preventing bearing oil leakage situation.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
