Abstract
The utility model discloses a screw gas pressure meter, which comprises a shell, a gas chamber cavity, a guide rod and a guide rod base, wherein the gas chamber cavity is arranged in the shell and communicated with a gas inlet nozzle, and the guide rod and the guide rod base are arranged in the gas chamber cavity; the guide rod base and the inner wall of the gas chamber cavity are hermetically provided with a silicon diaphragm therebetween, and the upper end of the guide rod is connected to a pointer through a transmission mechanism; the transmission mechanism is a screw arranged in an axially reserved screw hole at the upper end of the guide rod, the upper end of the screw is fixedly connected with the pointer, the upper part of the gas chamber cavity is provided with a positioning cover, the positioning cover and the screw are provided with a positioning piece therebetween, and screw in the positioning cover is provided with a return spring in a sleeve manner. The screw gas pressure meter is advantageous in that the pointer is driven to rotate through arranging the screw in the screw hole of the guide rod and driving the screw to rotate by using the vertical movement of the guide rod, thereby measuring the gas pressure; and the structure is simple, the operation is stable, the display precision is high, the service life is long, and the production and use cost is also reduced.
Description
Technical field
The utility model relates to tensimeter, especially relates to a kind of screw gas gauge.
Background technology
Tradition gaseous tension list structure many by hairspring, extension spring, eardrum, fall bar, clock pin gear and semi-circle gear and form.Clock pin gear and semi-circle gear engagement, lower end of the guide rod is gluing on eardrum, and its upper end is connected with semi-circle gear; Eardrum promotes guide rod and drives semi-circle gear, clock pin gear rotation under pressure.The gas gauge hairspring of said structure damages easily, and display precision is limited, and since its complex structure, maintenance difficult, operation stability is bad, and serviceable life is short, and production cost is higher.
Summary of the invention
It is a kind of simple in structure, stable that the utility model purpose is to provide, the screw gas gauge of long service life.
For achieving the above object, the utility model can be taked following technical proposals:
Screw gas gauge described in the utility model, it comprises housing, is arranged on the air chamber that is connected with admission piece in the described housing, and is arranged on guide pole and guide pole base in the air chamber; Sealing is provided with the silica gel diaphragm between described guide pole base and air chamber inwall, is connected with pointer in the guide pole upper end by gear train; The screw rod of described gear train in the screw that the guide pole upper end edge is axially offered, arranging, fixedly connected with pointer in described screw rod upper end, be provided with locating cover on described air chamber top, be provided with keeper between described locating cover and screw rod, the screw rod in described locating cover is set with retracing spring.
Described keeper is the capping that is fastened on locating cover upper shed position, offers through hole in the center of described capping, and described screw rod upper end is passed through hole and extended to capping top.
The utility model advantage is by in the screw of guide pole screw rod being set, and utilizes moving up and down of guide pole to drive the screw rod rotation, drives the pointer rotation thereby make, and then records the pressure of gas; Simple in structure, stable, the display precision height, long service life has also reduced production and use cost.
