The utility model discloses a kind of crank of diaphragm gas meter, comprise the first plastic shaft, the first plastic sheet, the second plastic shaft, the second plastic sheet, the 3rd plastic shaft, the 3rd plastic sheet and the 4th plastic shaft, the first described plastic shaft, the first plastic sheet, the second plastic shaft, the second plastic sheet, the 3rd plastic shaft, the 3rd plastic sheet and the 4th plastic shaft are in turn connected into integral structure.The crank of this diaphragm gas meter, structure is simple, design ingenious, all parts all adopt plastic material, save great amount of cost, and adopt the integral structure of mould single injection-molded, preparation section is simplified, and make the precision of product obtain effective guarantee, there is good practicality.
Description
Technical field
The utility model belongs to diaphragm gas meter technical field, is specifically related to a kind of crank of diaphragm gas meter.
Background technology
In existing diaphragm gas meter, its crank structure is complicated, and primarily of multiple metal shaft and sheet metal composition, adopt repeatedly riveting process to process, such crank structure is complicated, and cost is higher, dimensional accuracy does not reach requirement.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is the crank providing a kind of diaphragm gas meter, and structure is simple, and make easily, precision is high.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of crank of diaphragm gas meter, comprise the first plastic shaft, the first plastic sheet, the second plastic shaft, the second plastic sheet, the 3rd plastic shaft, the 3rd plastic sheet and the 4th plastic shaft, the first described plastic shaft, the first plastic sheet, the second plastic shaft, the second plastic sheet, the 3rd plastic shaft, the 3rd plastic sheet and the 4th plastic shaft are in turn connected into integral structure.
Described integral structure is that single injection-molded forms in a mold.
The first described plastic shaft is connected to one end of the first plastic sheet, and the second described plastic shaft is connected to the other end of the first plastic sheet, and the first plastic shaft and the second plastic shaft are positioned at the relative two sides of the first plastic sheet.
Second described plastic sheet one end is connected with the second plastic shaft, and the other end is connected with the 3rd plastic shaft, and the 3rd plastic shaft and the second plastic shaft are positioned at the relative two sides of the second plastic sheet.
The 3rd described plastic shaft and the 4th plastic shaft are located on the relative two sides of the 3rd plastic sheet, and position is relatively consistent.
The 3rd described plastic shaft diameter is greater than the 4th plastic shaft diameter.
Beneficial effect: compared with the conventional method, remarkable advantage of the present utility model comprises: the crank of this diaphragm gas meter, structure is simple, design ingenious, all parts all adopt plastic material, save great amount of cost, and adopt mould single injection-molded, preparation section is simplified, and makes the precision of product obtain effective guarantee, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crank of diaphragm gas meter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of crank of diaphragm gas meter, comprises the first plastic shaft 1, first plastic sheet 2, second plastic shaft 3, second plastic sheet 4, the 3rd plastic shaft 5, the 3rd plastic sheet 6 and the 4th plastic shaft 7; First plastic shaft 1 is connected to one end of the first plastic sheet 2, and the second plastic shaft 3 is connected to the other end of the first plastic sheet 2, and the first plastic shaft 1 and the second plastic shaft 3 are positioned at the relative two sides of the first plastic sheet 2.Second plastic sheet 4 one end is connected with the second plastic shaft 3, and the other end is connected with the 3rd plastic shaft 5, and the 3rd plastic shaft 5 and the second plastic shaft 3 are positioned at the relative two sides of the second plastic sheet 4.3rd plastic shaft 5 and the 4th plastic shaft 7 are located on the relative two sides of the 3rd plastic sheet 6, and position is relatively consistent.3rd plastic shaft 5 diameter is greater than the 4th plastic shaft 7 diameter.First plastic shaft 1, first plastic sheet 2, second plastic shaft 3, second plastic sheet 4, the 3rd plastic shaft 5, the 3rd plastic sheet 6 and the 4th plastic shaft 7, in a mold single injection-molded, form the crank with integral structure.
The crank of this diaphragm gas meter, structure is simple, and all parts all adopt plastic material, saves great amount of cost, and adopts mould single injection-molded, preparation section is simplified, and makes the precision of product obtain effective guarantee, have good practicality.
