Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
A kind of pressure gauge with buffer cup 13, including watchcase 1, fixing seat 2, bourdon tube 3, machine core 4, cover 5, indicate indicator
6 and inlet tube 7, the fixing end of the bourdon tube 3 be mounted in fixing seat 2 and be connected to inlet tube 7, the linkage magnification system
It is connect with the shift end of bourdon tube 3 and the displacement of shift end is transferred to indicate indicator 6, the linkage magnification system includes machine
Core 4 is equipped with buffer cup 13 in 1 shell of watchcase, and 4 axial axis of machine core is against the rim of a cup of buffer cup 13, buffering
Damping oil is equipped in cup 13, after machine core 4 installs, 4 axial axis of machine core just touches the damping oil in this buffer cup 13,
The sensitivity that machine core 4 can be promoted in this way, there is buffering function of seismic resistance, improves entire instrument function.
The inlet tube 7 and buffer cup 13 is concentric column.
The buffer cup 13 is hollow cylinder.
13 bottom of buffer cup is equipped with the chassis 19 that cross section is inverted triangle, internal as can be seen from Figure 4 to be equipped with for pressure
The air passage of table ventilation, but this local limited height, if flat, this place of buffer cup is just worn, and just can not
Damping oil is contained, buffering function of seismic resistance cannot be played, improve the functions such as entire instrument function, therefore 13 bottom of buffer cup is equipped with
The effect of cross section is the chassis 19 of inverted triangle, does not influence the function of air passage ventilation, nor affects on buffer cup 13.
