Abstract
A kind of non-linear display pressure gauge, including a connector, the connector is equipped with bourdon tube, pull rod is hinged on the bourdon tube, the pull rod other end is hinged on the lower end of rack lever, the rack lever upper end is equipped with arc-shaped rack, the arc-shaped rack engages connection with instruction gear, elastic block piece there are one being set on the bourdon tube, a locating part is additionally provided on the connector, the part of locating part is located at the top of elastic block piece, and being limited part when being deformed so as to the bourdon tube, after one distance of the elastic block piece movement blocks.The beneficial effects of the present invention are：Using elastic block piece is set on bourdon tube, so as to nonlinear can show bigger adaptability to changes in big pressure range.
Description
Technical field
The present invention relates to a kind of non-linear display pressure gauges.
Background technology
It is super to be often present with display in the case where running into big pressure and showing due to being linear change for present pressure gauge
The phenomenon that scope.Here we provide a kind of preceding semilinear and normally show pressure, the non-linear big pressure value of display of latter half
Pressure gauge.
The content of the invention
Meet the easy over range of big pressure to overcome the shortcomings of that existing linear display pressure gauge is shown, the present invention provides one
Kind is not easy the non-linear display pressure gauge of over range.
The present invention the technical solution to solve the technical problem is that：A kind of non-linear display pressure gauge, including a connector, institute
It states connector and is equipped with bourdon tube, pull rod is hinged on the bourdon tube, the pull rod other end is hinged on the lower end of rack lever,
The rack lever upper end is equipped with arc-shaped rack, and the arc-shaped rack engages connection with instruction gear, set on the bourdon tube
There are one elastic block piece, a locating part is additionally provided on the connector, the part of locating part is located at the top of elastic block piece, so as to
Part is limited during the bourdon tube deformation, after one distance of the elastic block piece movement to block.
The locating part is an elastic clamping hook, and the hook part of elastic clamping hook is located at the top of elastic block piece.
The elastic block piece is located at the end of bourdon tube.
Present invention additionally comprises following additional technical features：Instruction gear is connected with indicator, and the connector, which is equipped with, to be fixed
Piece, the arc-shaped rack are hinged on fixinig plate.
The present invention is when in use before the upper elastic block piece of bourdon tube meets locating part, and bourdon tube is as the prior art
Deformation, indicator is linear rotation.After elastic block piece meets locating part, bourdon tube receives a very big resistance, spring
Pipe deformation needs to overcome the adaptability to changes of elastic block piece could deform, and institute is so as to show very big pressure, this when is with pressure
Power changes, and indicator is non-linear rotation.
The beneficial effects of the present invention are：Using elastic block piece is set on bourdon tube, thus can in big pressure range
It is nonlinear to show bigger adaptability to changes.
Description of the drawings
Fig. 1 is the schematic diagram of one embodiment of the invention.
Fig. 2 to 4 is the schematic diagram of bourdon tube deformation three phases of the present invention, and wherein Fig. 2 is that elastic block piece not yet props up limit
The schematic diagram of position part, Fig. 3 are the schematic diagrames that elastic block piece has just propped up locating part, and Fig. 4 is schematic diagram after elastic block piece deformation, wherein
Arrow represents pressure direction.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
With reference to attached drawing 1 to 4, a kind of non-linear display pressure gauge, including a connector 1, the connector 1 is equipped with bourdon tube
2, pull rod 3 is hinged on the bourdon tube 2, and 3 other end of pull rod is hinged on the lower end of rack lever 4, the rack lever 4
Upper end is equipped with arc-shaped rack, and the arc-shaped rack engage connection with instruction gear 5, set on the bourdon tube 2 there are one it is elastic
Catch 6 is additionally provided with a locating part 7 on the connector 1, and the part of locating part 7 is located at the top of elastic block piece 6, so as to described
Part 7 is limited when bourdon tube 2 deforms, after one distance of the movement of elastic block piece 6 to block.
The locating part 7 is an elastic clamping hook, and the hook part 8 of elastic clamping hook is located at the top of elastic block piece 6.
The elastic block piece 6 is located at the end of bourdon tube 2.
Present invention additionally comprises following additional technical features：Instruction gear 5 is connected with indicator, and the connector 1 is equipped with solid
Stator 9, the arc-shaped rack are hinged on fixinig plate 9.
The present invention is when in use before the upper elastic block piece 6 of bourdon tube 2 meets locating part 7, and bourdon tube 2 is compared with technology
It equally deforms, indicator is linear rotation.After elastic block piece 6 meets locating part 7, bourdon tube 2 receives a very big resistance
Power, the deformation of bourdon tube 2 need to overcome the adaptability to changes of elastic block piece 6 could deform, institute so as to show very big pressure, this when
It waits with pressure change, indicator is non-linear rotation.
The beneficial effects of the present invention are：Using elastic block piece 6 is set on bourdon tube 2, so as in big pressure range energy
It is enough nonlinear to show bigger adaptability to changes.
