Abstract
The utility model discloses an air pressure meter, including a meter casing, a gear which is arranged in the middle of the meter casing and is equipped with a pointer and a driving mechanism which drives the gear to rotate. The driving mechanism is a rack, which meshes with the gear. The lower end of the rack is fixed with a pushing rod. The lower end of the pushing rod stretches into a cavity on the bottom of the meter casing. A lower opening of the cavity is connected with a circumscribed air guide joint in a way of sealing. The pushing rod in the cavity mentioned above is equipped with a return spring. The utility model is characterized in that the driving mechanism which consists of the rack meshing with the gear, the pushing rod fixed on the lower end of the rack and the return spring arranged on the pushing rod is adopted, which makes a hairspring unnecessary and greatly improves the service life of the meter body. The driving mechanism only consists of two parts of the rack fixed with the pushing rod and the return spring, which makes the structure simple and compact and the maintenance of the meter body convenient for users.
Description
Technical field
The utility model relates to tensimeter, especially relates to gas gauge.
Background technology
Tradition gaseous tension list structure is many to be made up of hairspring (disc spring), extension spring, eardrum, guide rod, clock pin gear and semi-circle gear.Clock pin gear and semi-circle gear engagement; Lower end of the guide rod gluing with eardrum on, its upper end be connected with semi-circle gear; Eardrum promotes guide rod and drives semi-circle gear, clock pin gear rotation under pressure, and hairspring, extension spring are used for the return of clock pin gear.The gas gauge hairspring of said structure is fragile, uses a period of time back-guiding rod usually to come off from eardrum; Because structure is complicated, damage that the back general user can not keep in repair voluntarily and the build-up of pressure statistical tables and reports are useless.
The utility model content
The utility model purpose is to provide a kind of gas gauge of simple in structure, long service life.
For achieving the above object, the utility model can be taked following technical proposals:
Gas gauge described in the utility model, it comprises watchcase, is arranged on described watchcase middle part and has the gear of pointer and drive the driving mechanism that described gear rotates; The tooth bar of described driving mechanism for being meshed with gear, described tooth bar lower end is fixed with a push rod, and described push rod lower end extends in the chamber of watchcase bottom; The under shed of described chamber is connected with external air guide joint sealing by elastic sealing gasket; Be set with retracing spring being positioned on the push rod of described chamber.
Described elastic sealing gasket is the U-shaped structure, and described push rod lower end is T shape structure and the bottom that extends to U-shaped structural elasticity sealing gasket.
The utility model advantage is by taking by the tooth bar that is meshed with described gear and be connected in tooth bar lower end push rod, and the retracing spring that is sleeved on the push rod forms driving mechanism, saved the hairspring disc spring, improved the serviceable life of table body greatly; Because driving mechanism only is made up of tooth bar and two parts of retracing spring of being fixed with one with push rod, make simple and compact for structurely, be convenient to very much the maintenance of user's his-and-hers watches body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, gas gauge described in the utility model, it comprises watchcase 1, is arranged on described watchcase 1 middle part and has the gear 3 of pointer 2 and drive the driving mechanism that described gear 3 rotates; The tooth bar 4 of described driving mechanism for being meshed with gear 3, described tooth bar 4 lower ends are fixed with a push rod 5, and described push rod 5 lower ends extend in the chamber 6 of watchcase 1 bottom; The under shed of described chamber 6 is tightly connected with external air guide joint 8 by the elastic sealing gasket 7 with U-shaped structure; On the push rod 5 that is positioned at described chamber 6, be set with retracing spring 9.Push rod 5 lower ends are T shape structure and the bottom that extends to U-shaped structural elasticity sealing gasket 7.
