Description

Liquid sample sampling bottle cap without frequently replacing spacer

Technical Field

The utility model relates to a sampling device technical field, concretely relates to liquid sample bottle lid of need not frequently changing the shock insulator.

Background

Glass bottle or plastic bottle of splendid attire reagent, according to colour, there are multiple classification mode such as shape and usage, among the prior art, when carrying reagent bottle and sampling needle, the thing is more, it is comparatively complicated, can not be fine through reagent bottle itself to the reagent extraction of inside, work efficiency has been reduced, sample bottle lid should be transported for this reason, but the white advance kind pad in the sample bottle lid is along with the increase of number of times of use, just lost the sealing effect, need often change, so extravagant material, and use cost is very high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a liquid sample bottle lid that need not frequently change the dottle pin, its sample is smooth and easy, need not trompil many times, the leakproofness is good, and the silicon rubber dottle pin can use very of a specified duration, has avoided the material extravagant, saves the cost.

In order to achieve the purpose, the application provides a liquid sample sampling bottle cap without frequently replacing a spacer, which comprises an external cover, the spacer and an internal bearing cover, wherein a fixed cavity is formed between the external cover and the internal bearing cover, the spacer is plugged in the fixed cavity, the inner wall of the lower part of the internal bearing cover is in threaded connection with a reagent bottle, and the outer wall of the lower part of the internal bearing cover is provided with a limiting clamping table which is in matched connection with an inner buckle of the external cover; and the external cover, the spacer and the internal bearing cover are all provided with sampling holes.

Further, the sampling holes on the external cover, the top of the spacer and the internal bearing cover are in a chamfer structure.

Furthermore, through the cooperation of interior buckle and spacing ka tai, the free rotation can be realized to outside lid.

Furthermore, during sampling, the sampling hole of the external cover is completely overlapped with the sampling holes of the spacer and the internal bearing cover.

Furthermore, when not sampling, the sampling hole of outside lid and the sampling hole of spacer, inside bearing lid avoid completely and realize sealedly.

Furthermore, the size of the sampling hole is matched with the outer diameter of the sampling needle.

Furthermore, the inner diameter of the fixing cavity is matched with the outer diameter of the spacer.

Furthermore, the isolation pad is a silicon rubber isolation pad.

The utility model discloses an above technical scheme, compare with prior art, the advantage that has is: this application reasonable in design, simple structure, the extraction of being convenient for simultaneously has improved work efficiency. The top cover can be rotated to perform sampling and sealing operations, and each sampling is performed in the same sampling hole, so that the sampling is smooth; the silicon rubber spacer is elastic, not easy to dissolve, tough and good in sealing performance, and can greatly reduce the replacement times of the spacer, avoid material waste and save cost. The sampling hole is in a chamfer structure, so that the needle insertion is easier.
