Abstract
The utility model discloses a gas pressure meter, which comprises a shell, a gear with a pointer and a driving mechanism driving the gear to rotate, wherein the gear is arranged at the middle part of the shell, the driving mechanism is a rack meshed with the gear, the lower end of the rack is fixedly connected with a guide rod, and the lower end of the guide rod extends to a positioning cavity inside the shell; the lower part of the positioning cavity is communicated with an air inlet nozzle, the positioning cavity is internally provided with a silicon extension tube whose one end is communicated with the air inlet nozzle, the silicon extension tube is externally provided with a tension spring in a sleeve manner, the lower end of the tension spring is fixedly connected with the bottom part of the positioning cavity, the upper end of the tension spring is provided with a spring upper end fixing member which moves up and down along the inner wall of the positioning cavity, and the spring upper end fixing member is fixedly connected with the lower end of the guide rod. The gas pressure meter has the advantages that the gear is driven to rotate by using variations of the silicon extension tube so as to enable the pointer to read a corresponding pressure value on a dial plate, thereby measuring the gas pressure. Compared with a traditional pressure meter, the gas pressure meter has the advantages of simple structure, good stability, convenient maintenance and long service life.
Description
Technical field
The utility model relates to tensimeter, especially relates to a kind of 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 eardrum usually comes off from guide rod after use a period of time, and since its complex structure, maintenance difficult, operation stability is bad, and serviceable life is short.
Summary of the invention
That the utility model purpose is to provide is a kind of simple in structure, easy to maintenance, the gas gauge of good stability, long service life.
For achieving the above object, the utility model can be taked following technical proposals:
Gas gauge described in the utility model, comprise watchcase, be arranged on the gear that described watchcase middle part has pointer, with the driving mechanism that drives described gear rotation, the tooth bar of described driving mechanism for being meshed with described gear, described tooth bar lower end is fixed with a guide rod, and it is indoor that described lower end of the guide rod extends to the positioning chamber of watchcase inside; The bottom of described location chamber is positioned at and is communicated with admission piece, be provided with the silica gel draw-tube that an end is communicated with described admission piece in that positioning chamber is indoor, described silica gel draw-tube is arranged with tension spring outward, fixedly connected with the location cavity bottom in the lower end of described tension spring, the upper end of tension spring is provided with along the spring upper end fixture that the positioning chamber chamber interior walls moves up and down, and described spring upper end fixture is fixedlyed connected with lower end of the guide rod.
The utility model advantage is to utilize the telescopic variation of silica gel draw-tube to drive the gear rotation that has pointer, makes pointer read corresponding pressure on the number at dial plate, thereby records the pressure of gas; Simple with traditional gas gauge structure compared, good operation stability, easy to maintenance, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, gas gauge described in the utility model, comprise watchcase 1, be arranged on the gear 3 that described watchcase 1 middle part has pointer 2, with the driving mechanism that drives described gear 3 rotations, the tooth bar 4 of described driving mechanism for being meshed with described gear 3, described tooth bar 4 lower ends are fixed with a guide rod 5, and described guide rod 5 lower ends extend in the location chamber 6 of watchcase 1 inside; The bottom of described location chamber 6 is positioned at and is communicated with admission piece 7, in the chamber 6 of location, be provided with the silica gel draw-tube 8 that an end is communicated with described admission piece 7, the described silica gel draw-tube 8 outer tension springs 9 that are arranged with, fixedly connected with chamber 6 bottoms, location in the lower end of described tension spring 1, the upper end of tension spring 9 is provided with along the spring upper end fixture 10 that location chamber 6 inwalls move up and down, and described spring upper end fixture 10 is fixedlyed connected with guide rod 5 lower ends.During use, when gas pressure change, promote silica gel draw-tube 8 telescopic variation, utilize the interaction between silica gel draw-tube 8 and the tension spring 9, thereby drive moving up and down of tooth bar 4, tooth bar 4 is being with gear 3 to rotate, and makes pointer 2 read corresponding numeral at dial plate, just can record gaseous tension.
