Description
Technical field：
The utility model is related to pressure gauge manufacture field, more particularly to a kind of anti-vibration pressure gauge.
Background technology：
Anti-vibration pressure gauge is widely used in the occasion of antivibration working environment, and instrument watchcase uses all-sealed structure, and filling
Glycerine or silicone oil, are not affected by with protective meter internal mechanism, reach the stable purpose of gauge pointer display, should
Product manufacture is complicated, and technological process is more, and maintaining inconvenience, production cost is high, and work time cost is big, while instrument is easy
Oil leak is produced, the oily bad phenomenons such as nigrescence of turning to be yellow have a strong impact on the normal of instrument and used.
Oil dumped pressure gauge shortcoming：Outward appearance tradition, using 304 stainless steels；Filling glycerine or silicone oil, are also easy to produce in watchcase
Oil leak, oil jaundice blacks, and influence is used；Manufacturing process is complicated, and technological process is long；Maintaining is inconvenient；It is produced into
This height, work time cost is more.
Utility model content：
In order to make up prior art problem, the purpose of this utility model is to provide a kind of anti-vibration pressure gauge, specious new
Grain husk, using ABS engineering plastics；Manufacturing process is simple, and technological process is short, and maintaining is convenient；Production cost is low, work time cost
It is few.
The technical solution of the utility model is as follows：
Anti-vibration pressure gauge, including watchcase, watchcase top surface are provided with minute surface, and case side wall is provided with joint, it is characterised in that：Institute
The bourdon tube of c-type is installed, bending is extend into joint downwards for bourdon tube one end, and the bourdon tube other end connects in the watchcase inner chamber stated
Gear drive is connect, gear drive includes being provided with and its phase on the outside of the central gear being installed in watchcase, central gear
The sector gear mutually engaged, sector gear end is provided with antivibration adjusting rod, and antivibration adjusting rod is provided with living in adjustment hole, adjustment hole
Dynamic to be connected with two flexible draw bars, two flexible draw bar other ends are articulated with a bit with spring tube end；Gear drive
Central gear central axle sleeve is equipped with the table board being fixed in watchcase, central shaft and is set with pointer.
Described anti-vibration pressure gauge, it is characterised in that described watchcase uses ABS engineering plastics injection mouldings.
Described anti-vibration pressure gauge, it is characterised in that be provided with the anticreep that fixed pointers come off at the top of described central shaft
Cap head, table board dead-center position is provided with stop.
The utility model has the advantages that：
The specious novelty of the utility model, using ABS engineering plastics；Using antivibration gear drive；Manufacturing process
Simply, technological process is short, and maintaining is convenient；Production cost is low, and work time cost is few.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is gear drive structural representation of the present utility model.
Embodiment：
Referring to accompanying drawing：
Anti-vibration pressure gauge, including watchcase 1, the top surface of watchcase 1 are provided with minute surface 2, and the side wall of watchcase 1 is provided with joint 3, watchcase 1
The bourdon tube 4 of c-type is installed, bending is extend into joint 3 one end of bourdon tube 4 downwards in chamber, the other end of bourdon tube 4 connection gear
Transmission mechanism 5, gear drive 5 includes being provided with and it on the outside of the central gear 5-1 being installed in watchcase 1, central gear 5-1
Intermeshing sector gear 5-2, sector gear 5-2 end are provided with antivibration adjusting rod 5-3, and antivibration adjusting rod 5-3 is provided with tune
Two flexible draw bar 5-5, two flexible draw bar 5-5 other ends and the end of bourdon tube 4 are connected with knothole 5-4, adjustment hole 5-4
Portion is articulated with a bit, and two flexible draw bar 5-5 are located at adjustment hole 5-4 centers both sides, and this gear transmission structure 5 is in measurement pressure
During stability more preferably, the accuracy of measurement is higher, and anti-seismic performance is also relatively strong；The centre tooth of gear drive 5
Wheel 5-1 central shafts 6, which are set with the table board 7 being fixed in watchcase, central shaft 6, is set with pointer 8.
Watchcase 1 uses ABS engineering plastics injection mouldings.
The top of central shaft 6 is provided with the anticreep cap head 9 that fixed pointers come off, and the dead-center position of table board 1 is provided with stop 10, it is ensured that
Pointer 8 will not be got over beyond zero crossing.
The utility model watchcase 1 buckles into formula modeling face using ABS engineering plastics and PC（Minute surface）2, internal structure uses antivibration
Gear drive 5, compensate for it is not oil-filled, can the vibration of anti-working environment technical barrier, all technical and antivibration grade
All meet virgin standard requirement, the table is specious, and novel, internal structure is compact, and manufacturing process is simple, technological process
Short, maintaining is convenient, and production cost is low, and work time cost is few, with stronger competitiveness.
