Abstract
The invention discloses a pressure meter comprising a housing. The rear part of the housing is connected with a base, and the front part of the housing is connected with a meter cover. A meter panel is arranged inside the meter cover. A pointer is arranged on the meter panel. One end of a spring tube is fixed on the base through a connecting tube, and the other end is connected to a central shaft through a connecting rod. The pointer is inserted into the central shaft. The base is internally provided with an air hole leading to the spring tube. According to the pressure meter, the connecting structure of the connecting rod and the central shaft replaces a movement, the product structure is simplified, the production cost can be reduced, and the service life can be prolonged. The housing, the base and the meter cover are integrally molded with plastics, processing and manufacturing are easier, the production cost is reduced, the impact of oxidation corrosion of metal materials to the appearance of the product is avoided, and environmental pollution caused by metal material surface electroplating is eliminated.
Description
Technical field
The present invention relates to a kind of instrument, particularly a kind of tensimeter.
Background technology
In the prior art, tensimeter comprises watchcase, and movement and erection joint are installed in watchcase, and movement is connected with pointer, and watchcase is externally connected to table cover, is provided with surface plate in table cover.Yet, in this tensimeter, in watchcase, need to arrange specific structure and fix movement, make structure complicated, and need to produce separately movement, production cost is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tensimeter of removing movement, simplifies product structure, reduces production costs.
In order to solve the problems of the technologies described above, a kind of tensimeter of the present invention, comprise housing, housing rear portion is connected with base, and housing front portion is connected with table cover, in table cover, be provided with surface plate, in surface plate, be provided with pointer, one end of a bourdon tube is fixed on base by connecting pipe, and the other end is connected to central shaft by connecting rod, described pointer is inserted on this central shaft, has the air hole that leads to bourdon tube in described base.
As the improvement of technique scheme, described surface plate is fixed on base.
As the improvement of technique scheme, described housing, base and table cover are injection molding.
The invention has the beneficial effects as follows: in this tensimeter, adopt the syndeton of connecting rod and central shaft to substitute movement, simplified product structure, be conducive to reduce production costs and increase the service life; And, housing, base and table cover are injection molding, and processing and manufacturing is easier, reduce production costs, and can avoid metal material oxidation corrosion and affect product appearance, also eliminated the pollution that metal material surface electroplating processes is brought to environment simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is one of inner structure schematic diagram of the present invention;
Fig. 3 is two of inner structure schematic diagram of the present invention;
Fig. 4 is three of inner structure schematic diagram of the present invention.
Embodiment
Referring to figs. 1 through Fig. 4, a kind of tensimeter of the present invention, comprise housing 1, housing 1 rear portion is connected with base 2, and housing 1 front portion is connected with table cover 3, in table cover 3, be provided with surface plate 4, the one end that is provided with pointer 5, one bourdon tubes 6 in surface plate 4 is fixed on base 2 by connecting pipe, and the other end is connected to central shaft 9 by connecting rod 8, described pointer 5 is inserted on this central shaft 9, has the air hole 7 that leads to bourdon tube 6 in described base 2.In this tensimeter, adopt the syndeton of connecting rod and central shaft to substitute movement, simplified product structure, be conducive to reduce production costs and increase the service life.
Wherein, described surface plate 4 is fixed on base 2, surface plate is installed more firm.
In addition, described housing 1, base 2 and table cover 3 are injection molding, and processing and manufacturing is easier, reduces production costs, and can avoid metal material oxidation corrosion and affect product appearance, also eliminated the pollution that metal material surface electroplating processes is brought to environment simultaneously.
The foregoing is only preferential embodiment of the present invention, as long as within the technical scheme that realizes the object of the invention with basic identical means all belongs to protection scope of the present invention.
