Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new
Type is not limited to listed embodiment.
As shown in Figures 1 to 4, a kind of dry type vibration-proof pressure gauge of the present embodiment includes gauge outfit 1, connecting tube 2, casing 3, shifting
Moving part 4, shaft 5, pointer 6 and spring 7, the connecting tube 2 are arranged in gauge outfit 1, and described sleeve pipe 3 is arranged in gauge outfit 1, connection
2 one end of pipe is plugged in 3 in casing, and the connecting tube other end stretches out gauge outfit.The moving member 4 is plugged in casing 3, the moving member
4 side is equipped with planar portions 41, and planar portions 41 are equipped with rack gear 42, and 5 outer surface of shaft is equipped with teeth portion 51, teeth portion and rack gear
Engagement.The pointer 6 is connect with shaft 5, and 7 both ends of spring are connect with casing 3 and moving member 4 respectively.Above-mentioned technical proposal
In, pressure pipe 8 is connect with connecting tube 2, and gas pressure is transferred in casing by pressure pipe, and gas pressure pushes moving member to move
Dynamic, moving member facing sleeve is mobile, so that shaft be driven to rotate, realizes indicators turn.In the present embodiment, pointer 6 and shaft 5 it
Between connected by connecting shaft 9, so that connecting shaft be made to be able to drive indicators turn.When the pressure disappears, the restoring force of spring 7 will move
