Problems solved by technology
[0002] This kind of bottle requires a large amount of reagents, which is easy to cause waste. When performing analysis experiments, the needle of the sampler is usually used to directly pass through the rubber cover to take samples. This operation may cause the needle to be blocked by rubber; if the rubber stopper is pulled out to take a sample , it often happens that the lid is not covered, which will easily cause reagent leakage when the sampling bottle is dumped, causing pollution to the outside world

The invention discloses a sampling device used for gas analysis, comprising a base and a bottle body, wherein the upper end of the bottle body is communicated with a bottleneck, the upper end of the bottleneck is in sliding connection with a first bottle cap, a vertical opening is formed in the first bottle cap, and the opening is in sliding connection with second bottle caps; serrated contact surfaces are arranged at the approaching ends of the second bottle caps, and the deviating ends of the second bottle caps are fixedly connected with a rotating rod; and one end, far away from the secondbottle caps, of the rotating rod is connected with a connecting ring. According to the device, the bottle cap can be removed by pressing the connecting ring, bottle cap can be closed by the action ofa spring, so as to facilitate sampling and analysis experiment, the connecting ring is connected with a chute in the first bottle cap by a clamping block, and the clamping block and the chute play a limiting role on the connecting ring, so as to ensure that the serrated contact surfaces among the second bottle caps can be sequentially connected.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sampling device for gas analysis. Background technique [0002] This kind of bottle requires a large amount of reagents, which is easy to cause waste. When performing analysis experiments, the needle of the sampler is usually used to directly pass through the rubber cover to take samples. This operation may cause the needle to be blocked by rubber; if the rubber stopper is pulled out to take a sample , Often the lid is not covered, which will easily cause reagent leakage when the sampling bottle is dumped, causing pollution to the outside world. Contents of the invention [0003] The object of the present invention is to propose a sampling device for gas analysis in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A sampling device for gas ana...
