Description
Technical field
The utility model is related to pressure gauge field, more particularly to a kind of pressure gauge of use rubber diaphragm structure.
Background technology
Pressure gauge is essential instrument in pneumatic commercial Application, and current pressure gauge generally uses Bourdon tube, profit
Central axis is driven with moving gear, then by gear with the deformation displacement of Bourdon tube, passes through angle of the pointer on label
Rotation reaches display pressure value.But the necessary secure seal of fixing end and free end for having individual drawback to be Bourdon tube, is generally used
It is scolding tin sealing, but can produces rosin joint during because of welding or other reasonses easily cause pressure gauge and tiny leakage occur or during using one section
Between after leak air phenomenon, build-up of pressure statistical tables and reports are useless or other accidents.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of pressure gauge of use rubber diaphragm structure, utilizes rubber
The deformation of glue film promotes rack, and move pointer by central shaft cingulum shows tested pressure value on label.Rubber diaphragm is the bottom of by
Seat is pressed abd fixed on joint, because rubber has good sealing property and tensile property, so as to prevent leakage phenomenon.
The utility model solves the technical scheme that its technical problem used：A kind of use rubber diaphragm structure is provided
Pressure gauge, including drain pan and joint, the upper end for being internally located at joint of described drain pan are provided with base, described base it is interior
Portion is horizontally installed with spring, and one end of described spring is connected with the rack slid laterally, one end of described base and joint
Upwardly extend rubber diaphragm be installed between portion, withstood in the middle part of one end of described rack and rubber diaphragm, described rubber
Upwardly extending for glue film and joint forms the pressure chamber being connected with joint between portion, and the upper end of described base is provided with mark
Rotating shaft is installed in the middle part of board, described label, the upper end of the rotating shaft is connected with pointer, the lower end of the rotating shaft is mutually nibbled with rack
Close.
As one kind supplement, the upper end of described drain pan is covered with watch glasses, and the upper end-face edge of the watch glasses is provided with a circle
Watchcase.
Further, cover plate is installed, described rotating shaft is passed through out of cover plate between the upper end of described base and label.
Further, one end end face of described rack has crossed out push rod between two parties, in the push rod and rubber diaphragm
Withstand in portion.
Beneficial effect the utility model is related to a kind of pressure gauge of use rubber diaphragm structure, using rubber diaphragm structure,
Rack is promoted using the deformation of rubber diaphragm, move pointer by central shaft cingulum shows tested pressure value on label.Rubber membrane
Piece is pressed abd fixed on joint by base, because rubber has good sealing property and tensile property, so that prevented leakage phenomenon,
Rubber diaphragm is fixed on joint by base, and spring and rack are arranged in base, and pressure reaches pressure by the hole of joint
Chamber, drives the pinion rotation of rotating shaft, drives the pointer being fixed in rotating shaft to be indicated in label by measuring pressure；After pressure is released,
Under the action of the spring, rack and diaphragm is promoted to reset, pointer zero.
Brief description of the drawings
Fig. 1 is the half-sectional structure chart of main view of the present utility model.
