Description
Technical field
The utility model relates to technology of instrument and meter field more particularly to a kind of gas negative pressure collection devices.
Background technique
In order to be detected to gas, needs scene to carry out the collection of gas, then transport to laboratory and examined again
It surveys.The device of gas collection is usually syringe cylinder structure, is sealed after pulling piston rod to carry out the suction of air to air inlet.
In actual use, the piston rod portion poor sealing effect of syringe, piston rod need constantly to sink to avoid outer
The entrance of portion's air is not suitable for long-distance transport, needs to improve.
Utility model content
The purpose of this utility model is to provide the convenience that a kind of gas negative pressure collection device, lift gas are collected, fortune
The entrance of outside air is avoided when defeated and storage.
For this purpose, the utility model uses following technical scheme:
A kind of gas negative pressure collection device, comprising: bottle body, pumping pipe fitting and collection assembly, bottle body top setting
Have a T shape bottleneck, the pumping pipe fitting is arranged in bottle body side, the collection assembly include straight tube, spring retainer ring, spring and
Bouncing ball, the straight tube lower part are arranged concentrically in T shape bottleneck, the support being provided on T shape bottleneck in the straight tube outer circle
It is provided with rubber ring progress environmental sealing at the top of ring, the filler ring and T shape bottleneck to fix, the spring retainer ring is arranged in straight tube
Bottom, the spring and bouncing ball are arranged in straight tube, and the bouncing ball is located at the top of spring, are provided at the top of the straight tube
Air inlet, the air inlet bottom are provided with arc groove corresponding with bouncing ball.
Wherein, the bottle body bottom is provided with flat base.
Wherein, the T shape bottleneck, bottle body, flat base and pumping pipe fitting are integrated glass structure or integration
Plastic construction.
Wherein, the pumping pipe socket end is provided with sealing cover.
Wherein, the sealing cover is elastic rubber sleeve.
Wherein, the straight tube is integrated plastic construction with filler ring.
The utility model has the beneficial effects that a kind of gas negative pressure collection device, using air extractor to pumping in laboratory
Gas-tpe fitting is evacuated, and negative pressure is formed in bottle body, and the sealing of pumping pipe fitting is then carried out using sealing cover, is transported existing
After, air inlet is inserted by thin stick, driving bouncing ball decline so that outside air enters bottle body and is collected, then takes out
Thin stick, bouncing ball reset under the action of the spring, and the closure for carrying out air inlet is bonded with arc groove, leakage problem is avoided, deposits
It stores up and transports and is more convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated below with reference to Fig. 1 and by specific embodiment.
A kind of gas negative pressure collection device, comprising: bottle body 1 is evacuated pipe fitting 3 and collection assembly, sets at the top of the bottle body 1
