Description
Technical field
The utility model belongs to instrument manufacture field, especially a kind of gas meter, flow meter drive shaft seal circle mounting structure.
Background technology
The installation sealing of gas meter, flow meter is very important, need, in table body, transmission shaft is installed according to the structure of instrument, transmission shaft installation site adopts double-layer seal rings, the mounting means of current employing be first by artificial different for diameter two O-ring seals are put into fill out successively cover and compress, install upper strata O-ring seal again after compressing lower floor's O-ring seal, O-ring seal installation effectiveness is low, and workman's labor capacity time is long, and easily cause and press-fit out-of-flatness, installation accuracy is difficult to ensure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structure is simple, the gas meter, flow meter drive shaft seal circle mounting structure of design science, processing ease, Labor-saving high-efficiency.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of gas meter, flow meter drive shaft seal circle mounting structure, it is characterized in that: comprise pedestal, column, transverse slat, cylinder, pressure head and back up pad, pedestal upper end is vertically fixed with a column, this column is provided with a transverse slat, transverse slat up-down adjustment is arranged on column, and this transverse slat cantilevered is stretched out, and is vertically provided with a cylinder in the middle part of transverse slat, the piston rod of this cylinder is passed down through transverse slat, and the piston-rod lower end below transverse slat is fixed with a pressure head mated with O-ring seal; On pedestal corresponding below pressure head, correspondence is fixed with a back up pad, and this back up pad is for supporting table body to be processed, and back up pad front end is shaped with multiple stopper slot mated with table body; Interval, back up pad upper end is fixed with multiple limited post.
And described back up pad lower end is fixed with support.
And described transverse slat rear end is fixed with a barometer, this barometer is used for observing and regulating operating air pressure with rain glass.
Advantage of the present utility model and good effect are:
Structure of the present utility model is comparatively simple, is placed in order by two O-ring seals and fills out lid position, adopts cylinder to press slowly and fills out in lid by press-in smooth for O-ring seal, install smooth specification, install effective, and product hermeticity is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of gas meter, flow meter drive shaft seal circle mounting structure, comprise pedestal 8, column 9, transverse slat 2, cylinder 1, pressure head 3 and back up pad 5, pedestal upper end is vertically fixed with a column, this column is provided with a transverse slat, transverse slat up-down adjustment is arranged on column to be needed to regulate transverse slat height according to processing, and this transverse slat cantilevered is stretched out, and is vertically provided with a cylinder in the middle part of transverse slat, the piston rod of this cylinder is passed down through transverse slat, and the piston-rod lower end below transverse slat is fixed with a pressure head mated with O-ring seal; On pedestal corresponding below pressure head, correspondence is fixed with a back up pad, and this back up pad is for supporting table body to be processed, and back up pad front end is shaped with multiple stopper slot 6 mated with table body; Interval, back up pad upper end is fixed with multiple limited post 4.
In order to ensure the stability of back up pad, be fixed with support 7 in back up pad lower end.
Be fixed with a barometer 10 in transverse slat rear end, this barometer is used for observing and regulating operating air pressure with rain glass.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
