Abstract
The utility model provides a range limit structure of a pressure meter pointer, and belongs to the technical field of machinery. The range limit structure solves a problem that an existing pressure meter pointer does not have an upper limit and a lower limit. A pressure meter comprises a meter housing, a dial disposed in the meter housing, and a bourdon tube disposed on the dial. The dial is also provided with a rotating shaft. The rotating shaft is provided with a pointer. The bourdon tube is connected with the rotating shaft in a transmission manner through a driving medium. The range limit structure comprises a limited post disposed on the dial, and a first limiting portion disposed on the driving medium. When the pointer is pointing to a maximum value on the dial, the first limiting portion is abutted against on the limited post. The range limit structure is advantaged by effectively limiting a pointer of the pressure meter and structure design is reasonable, etc.
Description
Technical field
The utility model relates to a kind of stroke limit structure of stroke limit structure, particularly a kind of gauge hand.
Background technology
When in petroleum pipe line, carrying out the conveying of liquid or gas, need be in pipeline the setting pressure instrument, be used for detecting at any time the pressure of pipeline medium.Existing manometer can be divided into two big classes substantially: a class is traditional electromechanical pressure instrument, and another kind of is digital manometer.The electromechanical pressure instrument is the Passive Shape Control device, and namely dispense with outer connecting power gets final product work, has cheap, convenient for installation and maintenance advantage.Common electromechanical pressure instrument is because unreasonable its accuracy of detection that causes of its structural design is lower, and digital manometer needs external power supply to work, and is not suitable for being used in pipeline and carries.But prior mechanical tensimeter no maximum and lower limit, i.e. the deflection of pointer does not have maximal value and minimum value, can not accurately measure atmospheric pressure value.Security incident takes place in the hyperbar value in the measuring channel easily immediately when air pressure surpasses the hyperbar value of pipeline.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of reasonable in design, can effectively carry out the stroke limit structure of spacing gauge hand to pointer.
The purpose of this utility model can realize by following technical proposal:
A kind of stroke limit structure of gauge hand, tensimeter comprises watchcase, be located at the index dial in the watchcase and be located at bourdon tube on this index dial, also be provided with rotating shaft on the described index dial, described rotating shaft is provided with pointer, above-mentioned bourdon tube is in transmission connection by a driving member one this rotating shaft, it is characterized in that, this position limiting structure comprises the limited post be located on the index dial and is positioned at limiting section one on the above-mentioned driving member, and this limiting section one is resisted against on the limited post during described pointed index dial greatest measure.
In the stroke limit structure of above-mentioned gauge hand, also be provided with the locating part that is constituted by fixed part and stop part on the described index dial, described fixed part is fixed on the index dial, described stop part outwards bends and is positioned at the outside of above-mentioned bourdon tube, and bourdon tube is resisted against on this stop part during described pointed index dial greatest measure.
In the stroke limit structure of above-mentioned gauge hand, also have on the described driving member be used to the limiting section two that prevents that driving member from coming off from rotating shaft, and also be provided with reference column on the described index dial, described pointer was resisted against out on the reference column when described bourdon tube was undeformed.
Compared with prior art, the stroke limit structure of this gauge hand has the following advantages: this position limiting structure can limit manometric pointer, makes it at range and minimum stroke bias internal, is connected firmly between driving member and the rotating shaft, be difficult for becoming flexible long service life, measuring accuracy height.

Among the figure, 1, watchcase; 2, index dial; 3, bourdon tube; 4, rotating shaft; 5, pointer; 6, driving member; 61, limiting section one; 62, limiting section two; 7, limited post; 8, locating part; 81, fixed part; 82, stop part; 9, reference column.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, tensimeter comprises watchcase 1, be located at the index dial 2 in the watchcase 1 and be located at bourdon tube 3 on this index dial 2, also is provided with rotating shaft 4 on the index dial 2, and rotating shaft 4 is provided with pointer 5, and bourdon tube 3 is in transmission connection by a driving member 6 one these rotating shafts 4.
As shown in Figure 3, the stroke limit structure of this gauge hand comprises the limited post of being located on the index dial 27 and the limiting section 1 that is positioned on the driving member 6, and this limiting section 1 was resisted against on the limited post 7 when pointer 5 pointed to index dials 2 greatest measures.
As shown in Figure 2, also be provided with the locating part 8 that is constituted by fixed part 81 and stop part 82 on this index dial 2, fixed part 81 is fixed on the index dial 2, and stop part 82 outwards bends and be positioned at the outside of bourdon tube 3, and bourdon tube 3 was resisted against on this stop part 82 when pointer 5 pointed to index dial 2 greatest measures.
As shown in Figure 3, also have on the driving member 6 be used to the limiting section 2 62 that prevents that driving member 6 from coming off from rotating shaft 4, and also be provided with reference column 9 on the index dial 2, pointer 5 was resisted against out on the reference column 9 when bourdon tube 3 was undeformed.
The stroke limit structure of this gauge hand can limit manometric pointer 5, makes it at range and minimum stroke bias internal, is connected firmly between driving member 6 and the rotating shaft 4, is difficult for becoming flexible long service life, measuring accuracy height.
