Body, lower part are hollow cylinder and I-shaped cone inner ring diameter is less than the cylinder inner ring diameter, and the column side wall is equipped with
Through-hole, it is described to pull out that button connection column bottom is hollow cone and seals, top is that hollow cylinder and side wall are equipped with through-hole, it is described to pull out
Button connecting column upper hollow cylinder protrudes into described pull out in button portable pillar lower hollow cylinder and the through-hole of the two is located at same axis
Line, the pin are set to described pull out and buckle connecting column upper hollow cylinder and pull out in the through-hole for buckleing portable pillar lower hollow cylinder, institute
Steel ball is stated set on the spring inner ring and is located at described pull out and buckle connecting column lower hollow cone top surface and buckle portable pillar lower part with pulling out
Between hollow cylinder bottom surface, the upper fixture block and lower fixture block are respectively arranged on the top surface of the spring outer ring and bottom surface and clamp institute
State spring.
Further, the button I-shaped pyramid side in portable pillar top that pulls out is arcwall face, and the diameter of the arcwall face is
71.5mm±0.1mm。
Further, the upper fixture block and lower fixture block clamp the spring medial surface be and the matched arc of spring outer diameter
Face.
Box cover structure due to the utility model for Pneumatic sample sending box uses above-mentioned technical proposal, i.e. this box cover structure
Pull out that button portable pillar top is hollow I-shaped cone, lower part is that hollow cylinder and I-shaped cone inner ring diameter are less than column
Internal loop diameter, column side wall be equipped with through-hole, pull out button connection column bottom be hollow cone and seal, top be hollow cylinder and
Side wall be equipped with through-hole, pull out button connecting column upper hollow cylinder protrude into pull out button portable pillar lower hollow cylinder in and the two through-hole
Positioned at same axis, pin is set to pull out and buckles connecting column upper hollow cylinder and pull out in the through-hole for buckleing portable pillar lower hollow cylinder,
Steel ball, which is set to spring inner ring and is located to pull out to buckle connecting column lower hollow cone top surface and pull out, buckles portable pillar lower hollow cylinder bottom
Between face, upper fixture block and lower fixture block are respectively arranged on top surface and bottom surface and the clamp springs of spring outer ring.This box cover structure overcomes
Conventional specimen box box cover is easily stuck in the defect of pneumatic transmission pipeline, avoids the blocking of pneumatic transmission pipeline, improves the efficiency of transmission of sample, it is ensured that
The analysis of components data for obtaining sample in time, guarantee the rhythm of production of steel-making iron-smelting process.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing:
Fig. 1 is the box cover structural schematic diagram that the utility model is used for Pneumatic sample sending box.
