Description
Technical field
This utility model relates to technology of instrument and meter field, especially a kind of anti-vibration pressure gauge.
Background technology
Pressure gauge is mainly used in monitoring the operating pressure of the internal institute such as pressure-vessel, pipeline and pipeline filling medium, in order to control rightly
Pressurized capacity processed, the safety of protection equipment, or by grasping pressure parameter, monitor for operator, control and regulate production
Thering is provided reliable foundation, therefore, Pressure gauge can be widely used in the necks such as automobile, engineering machinery, coal mine equipment, chemical industry equipment
Territory, is a kind of very important instrument and meter.
The movement of general anti-vibration pressure gauge use before and after the parts composition such as clamping plate, sector gear, central gear, hairspring and pointer,
Similar with ordinarily manometer, after general assembly, in table, it is filled with white oil.Pressure gauge operationally, if ambient environment vibrations amplitude is relatively
Time big, it is possible to hairspring can be made to be intertwined with central gear, cause Pressure gauge to damage.In consideration of it, to anti-vibration pressure gauge
Design and structure be improved further.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of anti-vibration pressure gauge, at hairspring and center
Catch is increased, it is to avoid hairspring is wound around with central gear between gear.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one anti-vibration pressure gauge, including watchcase, front plate, rear plate, joint, graduated disc, pointer, spring
Pipe, sector gear, central gear and hairspring, also include catch, and the bottom of watchcase is fixed with joint, and joint is fixed with fore-clamp
Plate, central gear is fixed between front plate and rear plate by mandrel, and central gear engages with sector gear, and sector gear is solid
Being scheduled on rear plate, one end of bourdon tube is connected with sector gear, and the other end of bourdon tube is connected with joint, one end set of mandrel
Being provided with hairspring, the other end of mandrel is arranged with graduated disc and pointer, is fixed with catch between hairspring and central gear.
Further, central gear is sheathed on the centre of mandrel.
Further, hairspring is between rear plate and central gear.
Further, the other end of mandrel runs through graduated disc and the center of pointer and fixes.
Further, the center of graduated disc, central gear, hairspring and catch is on same straight line.
Further, catch is circular, and the diameter of catch is not less than the diameter of hairspring.
The beneficial effects of the utility model: increase catch between manometric hairspring and central gear, when using Pressure gauge,
Stop that hairspring is wound around with central gear, it is ensured that Pressure gauge normally uses.

Fig. 2 is side sectional view of the present utility model.
Detailed description of the invention
Embodiment cited by this utility model, is only intended to help and understands this utility model, should not be construed as this utility model
The restriction of protection domain, for those skilled in the art, on the premise of without departing from this utility model thought,
Can also make improvements and modifications this utility model, these improve and modify the model also falling into the protection of this utility model claim
In enclosing.
As shown in Figure 1-2, a kind of anti-vibration pressure gauge, including watchcase 1, front plate 2, rear plate 3, joint 4, graduated disc 5,
Pointer 6, bourdon tube 7, sector gear 8, central gear 9, hairspring 10 and catch 11, the bottom of watchcase 1 is fixed with joint 4,
Being fixed with front plate 2 on joint 4, central gear 9 is sheathed on the centre of mandrel 12, and central gear 9 is fixed by mandrel 12
Between front plate 2 and rear plate 3, central gear 9 engages with sector gear 8, and sector gear 8 is fixing on the back cover 3,
One end of bourdon tube 7 is connected with sector gear 8, and the other end of bourdon tube 7 is connected with joint 4, and one end of mandrel 12 is arranged with
Hairspring 10, hairspring 10 is between rear plate 3 and central gear 9, and the other end of mandrel 12 runs through graduated disc 5 and pointer 6
Center and fix, be fixed with catch 11 between hairspring 10 and central gear 9.Catch 11 is circular, and the diameter of catch 11 is not
Diameter less than hairspring 10.The center of graduated disc 5, central gear 9, hairspring 10 and catch 11 is on same straight line.
During use, being connected with measured object by Pressure gauge, Pressure gauge starts to detect the pressure of measured object, bourdon tube 7 motion drive with
Its sector gear 8 connected moves, and sector gear 8 drives central gear 9 to move, and central gear 9 band moving mandrel 12 moves,
Mandrel 12 drives pointer 6 to walk about, and hairspring 10 controls the reciprocating motion of pointer.It is increased between hairspring 10 and central gear 9
Diameter, not less than the catch 11 of hairspring 10 diameter, when ambient vibration amplitude descends more greatly use Pressure gauge around, can stop trip
Silk 10 is wound around with central gear 9, it is ensured that Pressure gauge normally uses.If the diameter of catch 11 is less than the diameter of hairspring 10,
Hairspring 10 beyond part is also to be wound around with central gear 9, and therefore, the diameter of catch 11 needs more than or equal to hairspring
The diameter of 10.
