Description

Micro and quantitative anti-falling disposable sampler

Technical Field

The utility model relates to the technical field of samplers, in particular to a micro and quantitative anti-falling disposable sampler.

Background

In general, in the course of medical testing and food safety testing, it is necessary to collect, store, transport and analyze target analytes. In the collection process, when the target analyte is liquid, a sampler with a suction pipe is usually used for directly collecting the target analyte, and the liquid is sucked into the sampler through pressure difference. At present, most samplers used for collecting liquid adopt a screw cap, and the screw cap and a bottle body are fixed through the matching of screw threads and screw threads; and the bottle body and the sampler are fixed in an interference fit manner. However, these fixing methods result in poor sealing performance of the sampler, and after long-term use, the matching of the screw threads and the screw threads or the interference fit between the body and the sampler easily causes deformation of the material of the sampler, so that the sampler is easily separated from the body.

Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 to 6, in the present embodiment, the micro and quantitative anti-drop disposable sampler includes a sampling head 22 and a bottle body 1, wherein the sampling head 22 is formed with an anti-drop slot 221, a sealing platform 21 having an annular structure, and a straw 23 for sucking liquid. Anticreep draw-in groove 221 and the platform 21 that seals form respectively in the lateral surface of sampling head 22, wherein, seals the top that platform 21 is located anticreep draw-in groove 221, and, the anticreep draw-in groove is the annular and arranges on the outer peripheral face of sampling head. The sampling head 22 is a hollow cylindrical structure, wherein the suction pipe 23 is vertically arranged at a hollow position in the middle of the sampling head 22, and the suction pipe 23 is preset with a through hole 231 vertically penetrating the sampler. The outer peripheral surface of the sealing platform 21 is concavely formed with an auxiliary notch 211, and when the sealing platform 21 needs to be rotated, the auxiliary notch 211 can be used as a force application position, so that the sealing platform 21 can be easily rotated.

In this embodiment, the inner wall of the bottle mouth of the bottle body 1 is formed with a first annular sealing portion 13, a locking block 15 and a second annular sealing portion 14, wherein the locking block is annularly arranged on the inner wall of the bottle mouth. The first annular sealing part 13 is located above the anti-falling fixture block 15, and the second annular sealing part 14 is located below the anti-falling fixture block 15. The outer peripheral surface of the bottle mouth of the bottle body 1 is formed with a ring-shaped bottle mouth platform 11.

In this embodiment, the lower end of the sampling head 22 is fitted into the mouth of the body 1 by rotating the sampler. When inlaying the lower extreme of sampling head 22 completely and adorning in the bottleneck of body 1, seal platform 21 and laminating each other with bottleneck platform 11, the sample thief is accomplished the equipment with body 1, at this moment, first annular seal portion 13 and second annular seal portion 14 all with the bottleneck inner wall interference fit of body 1, make sampling head 22 and body 1 reciprocal anchorage, and, anticreep fixture block 15 inlays and adorns in anticreep draw-in groove 221, make sampling head 22 be difficult to extract from body 1. Further, the first annular sealing part 13, the sealing platform 21 and the bottle mouth platform 11 which are mutually attached prevent external air from entering the tube; the liquid in the pipe is prevented from flowing to the anti-drop clamping groove 221 or flowing out of the pipe by the second annular sealing part 14. When the sampling head 22 is completely embedded in the bottle opening of the bottle body 1, the sampling head 22 can be rotated and separated from the bottle opening of the bottle body 1 by rotating the sampling head 22 and pulling the sampling head 22 in the direction away from the bottle body 1. The sampler is sealed by the interference fit of the first annular sealing part 13 and the second annular sealing part 14 with the inner wall of the bottle mouth of the bottle body 1 respectively and by the mutual attachment of the sealing platform 21 and the bottle mouth platform 11.
