Description
Technical field
The utility model relates to detecting instrument field, specifically, relates to a kind of filter paper volume stationary installation in detecting instrument.
Background technology
Along with air quality receives the concern of the people day by day, the monitoring of air particle mass concentration develops into present many employing β ray reference methods from the concussion sedimentation balance method of classics; On-line monitoring instrument many employings filter paper volume of β ray reference method realizes Enrichment and the conveying of particle, long paper tape both as the carrier of sampling, again as the instrument carried.Therefore require that coil paper system must realize fixation, easy accessibility, be easy to change filter paper, must meet and being synchronized with the movement of rotating shaft, accurately move to realize filter paper and control;
The hard contact mode of prior art many employings stationary shaft and the concavo-convex inlay card of external component fixes filter paper, this kind of device because inside and outside metal or hard material hardness larger, machining precision is not enough to reach the good degree that both coordinate tightly, both dismounting and change convenience performance characteristics coexists, often cause interior exterior conjunction part to exist and coordinate free gap, thus the accurate and rotating shaft synchronizing moving of filter paper can not be ensured, cannot ensure accurately collected specimens to be delivered to measuring position, cause measurement result inaccurate.
Utility model content
In view of this, need to overcome at least one in above-mentioned defect of the prior art.The utility model provides a kind of filter paper volume stationary installation, comprising:
Axle;
Front and rear baffle, is made up of jointly front apron and backboard, and described backboard and described axle are connected, and described axle is arranged on the axis of described front and rear baffle, and described front apron is arranged on the opposite side of described axle;
Filter paper ring, described filter paper ring is hollow, internal diameter and described axle major diameter fit, and is arranged on inside described front apron, described filter paper ring external diameter and filtration paper cylinder minor diameter fit;
O type elastic body, described O type elastomer sleeve is on the external diameter of described axle, and quantity is n;
Extrusion ring, described extrusion ring internal diameter and described axle major diameter fit also can slide on the shaft, and described extrusion ring external diameter is less than described filter paper ring external diameter;
Compress knob, described compression knob is arranged on the outside of described front apron, is connected with described axle, and in screwing operations, can promote the described extrusion ring of extruding and described O type elastic body, make described O type elastomeric intumescent by filter paper hoop.
According in the utility model background technology to described in prior art, can not ensure that filter paper is accurate with rotating shaft synchronizing moving, thus cause mobile accuracy poor, and structure member (embossed card is clamped to be put) difficulty of processing is comparatively large, complexity is installed in operation; And the filter paper volume stationary installation that the utility model provides, expand by utilizing O type elastic body self to be squeezed, filtration paper cylinder is extruded, filtration paper cylinder is made to be fixed on described filter paper ring, synchronous with the rotation of described axle, it is simple and practical, easy accessibility, exert a force stressed continuous uniform simultaneously, and regulate convenient.
In addition, disclosed in the utility model, filter paper volume stationary installation also has following additional technical feature:
Further, described front apron is transparent material baffle plate.
Further, described O type elastic body is O RunddichtringO.
Further, described O type elastic body is O type rubber ring.
