Abstract
The invention discloses a kind of load transducer elastomeric components sealing structures, including elastomeric components, housing and pedestal, elastomeric components are strip structure, housing is tubular construction, and one end of housing has boss, and one end of elastomeric components is extended to by one end of the housing in housing, outer eaves is provided on elastomeric components, and the outer eaves is fastened on the outside of the boss of shell end, pedestal is fixedly installed on the other end of housing, and one end of the elastomeric components is fixed on pedestal.This configuration reduces the risks of end face seal failure, solve the problems, such as existing load transducer using a period of time with regard to leak.Belong to mechanical structure waterproof technique field.
Description
Technical field
The present invention relates to a kind of load transducer elastomeric components sealing structures, belong to mechanical structure waterproof technique field.
Background technology
Oilfield test oil well work(figure majority uses indicator, which need to use load transducer.The load passes at present
The elastomeric components of sensor use end face seal, and this end face seal will be repeatedly sent out under stressing conditions repeatedly in elastomeric components
Raw deformation, once there is deformation that can be penetrated into elastomeric components slowly along end face in rainy day rainwater, corrosion strain conversion circuit is broken
Bad load detect, indicator cannot proper testing load, so as to influence routine test of the oil field to oil well work(figure.
Invention content
It is an object of the invention to：A kind of load transducer elastomeric components sealing structure is provided, end face seal is reduced and loses
The risk of effect solves the problems, such as existing load transducer using a period of time with regard to leak.
To achieve the above object, intend using such a load transducer elastomeric components sealing structure, including elastomer
Component, housing and pedestal, elastomeric components are strip structure, and housing is tubular construction, and one end of housing has boss, elasticity
One end of body component is extended to by one end of the housing in housing, outer eaves is provided on elastomeric components, and the outer eaves fastens
In the outside of the boss of shell end, pedestal is fixedly installed on the other end of housing, and one end of the elastomeric components is fixed
In on pedestal.
It seals and fixes in aforementioned seal structure, between the other end and pedestal of the housing；
In aforementioned seal structure, the boss is set along the circumferencial direction that shell end is open, and the cross section of boss is step
Structure, the outer eaves on elastomeric components are lid formula structure, and the step groove to match with boss is provided on the inside of outer eaves, i.e., recessed
Slot is coated on the outside of boss on the outside of outer eaves.
Compared with prior art, the present invention is only needed when mounted by the improvement to existing load transducer waterproof construction
By in the groove of the boss press-in elastomeric components of the housing of this load transducer, end face seal failure can not occur again
Problem so as to reduce onsite application risk, improves assembling product efficiency, and solve current load transducer using one section when
Between will leak the problem of.
