The utility model is scientific and reasonable for structure, and mileometer adjustment is flexible, and versatility is good.The utility model improves material, alleviates
Weight reduces the cost of production.The good product quality, high-efficient of the utility model production, accuracy is preferable.The utility model
The technology innovation of this field is promoted, there is the meaning of progress.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model cross section structure schematic diagram；
Fig. 2 is the utility model overall structure diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with specific embodiment
The present invention will be further described in detail.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term is " even
Connect ", " installation ", " fixation " shall be understood in a broad sense, for the ordinary skill in the art, can be understood with concrete condition on
State the concrete meaning of term in the present invention.
As shown in Figs. 1-2, convenient for the core of pressure meter of adjusting, the pillar 3 including upper clamp plate 1, lower clamp plate 2 and centre,
The upper clamp plate 1 is fixed on pillar 3 with lower clamp plate 2 by way of riveted.Also cause between upper clamp plate 1, lower clamp plate 2 above
There are a certain distance, the convenient installation with lower component.
The present embodiment also resides in: shaft gear 4, shaft 5, shaft gear are also respectively provided between upper clamp plate 1 and lower clamp plate 2
4 position between shaft 5 and pillar 3, it is scientific and reasonable.Above-mentioned shaft gear 4, shaft 5 can be in upper clamp plates 1, lower clamp plate 2
The rotation of axial direction may be implemented in upper moving rotary.The present embodiment also resides in: further include sector gear 6 and with pulling-on piece 7.
Above-mentioned component is specifically provided in: sector gear 6 includes scalloped end 61 and connecting pin 62, and connecting pin 62 is perpendicular to scalloped end
61,62 Construction integration of the scalloped end 61 and connecting pin is easy to produce.The curved angle of scalloped end 61 is 60 °, guarantees scalloped end
61 is arc toothed, change traditional evolvent type, power transmission is more accurate.
It is equipped with the gear teeth being meshed with shaft gear 4 at the edge of scalloped end 61, can be realized scalloped end 61 and 4 phase of shaft gear
Mutually engagement power transmission.Connecting pin 62 is fixed in shaft 5, and connecting pin 62 is moved synchronously with shaft 5.In the tail portion of connecting pin 62
Equipped with the pintle a being upturned, the shape of pintle a is U-shaped shape.The end of pintle a passes through rivet interlacement on pulling-on piece 7, this reality
Applying example and also residing in pulling-on piece shape is " Ω ", and pintle a is flexibly connected with pulling-on piece 7.
To guarantee that whole device makes gear remain one way engagement in transmission, the issuable biography of gear backlash is eliminated
Dynamic idle running.The present embodiment is also provided with balance spring 8, and between upper clamp plate 1, lower clamp plate 2, the center of balance spring 8 passes through the balance spring 8
The mode of riveted is fixed on shaft gear 4, and the pillar 3 is equipped with groove 31, and the edge of the balance spring 8 is by way of riveted
It is fixed in groove 31.
