Description

Pipeline fixing structure and bottle cap

Technical Field

The application mainly relates to a pipeline fixing structure, in particular to a fixing structure of a pipeline for sampling a reagent and a bottle cap.

Background

At present, reagents are used in industries such as environmental monitoring, for example, an automatic water quality monitor can make corresponding substances in water participate in the reagents through chemical agents. And then calculating the content of corresponding substances in the water by a colorimetric method, a titration method, conductivity measurement and other methods. Among them, reducing the registration of reagents and reducing the frequency of reagent replacement can greatly reduce the burden on the operator. And the frequency of reagent replacement is reduced, and the interruption of analysis due to insufficient reagent can be prevented. However, in the actual sampling process, the sampling pipeline is frequently taken away from the bottom of the reagent bottle, which leads to frequent consequences such as low reagent utilization rate, reduced analysis efficiency and the like.

The existing sampling bottle sampling technology is to punch a hole on a bottle cap to insert a pipeline during use, and no measure for fixing the pipeline is provided. As shown. The pipeline passes through the bottle lid and places in the reagent bottle. When a sample is extracted from the upper port, the pipeline is easily driven to enable the lower port to leave the bottom of the bottle. During operation, collect reagent instrument and collect reagent through reagent bottle pipeline and put into the sample and detect. If the tube is fixed, the sample can be taken. If the pipeline is not fixed, the pipeline is inserted into the bottle end freely, and the pipeline can be driven by 0.05N force. That is, any operation only needs to touch the pipeline, the pipeline is driven, and whether the sampling port of the pipeline can touch the bottom of the bottle or not cannot be guaranteed. If pipeline bottom port can not contact the bottle bottom, bottom reagent will not be extracted, and then lead to still not arriving the change time, can not get reagent, influence sample detection efficiency, or have phenomenons such as extravagant reagent.

Fig. 1 is a schematic view of a pipeline fixing structure according to a first embodiment of the present application. Fig. 2 is a sectional view of a pipe fixing structure according to a first embodiment of the present application. Fig. 3 is a diagram illustrating the operation of the pipe fixing structure according to the first embodiment of the present application.

As shown in fig. 1 and 2, the pipe fixing structure disclosed in this embodiment includes a threaded hole 1, a hollow screw 2, and a curved bearing 3. In this embodiment, the curved carrier 3 is a conical ferrule.

As shown in fig. 1 and 2, the threaded hole 1 includes a bottom 11 through which a pipeline can pass, a top opening 12, and an internal middle thread 13. The threaded hole is a blind hole. The threaded hole 1 is arranged at the middle convex part of the bottle cap. The bottom 11 is at a certain thickness from the bottom end of the bottle cap bulge. The plane of the top opening 12 of the threaded hole and the plane of the top of the bottle cap are positioned on the same plane. The internal intermediate thread 13 is cylindrical, but not limited thereto. The height of the threaded hole is preferably matched with the height of a projection of an applied reagent bottle cap. It should be understood that the shape, size, etc. of the threaded hole may be set according to actual conditions, and it is only necessary to secure the threaded hole to be screwed with a screw. And are not intended as limitations on the present application.

As shown in fig. 1 and 2, the cannulated screw 2 comprises an upper screw head 21, a lower thread 22 and a hollow portion 23. The lower thread 22 is a cylindrical external thread which can cooperate with the internal intermediate thread 13 of the threaded hole 1. Namely, the lower thread 22 can be screwed into the internal thread 13 of the hole of the thread 1, so as to meet the engineering matching requirement. The upper screw head 21 and the lower screw thread 22 are of a matching engineering size and have a smooth or rough surface for the user to tighten, optionally in any manner of circular or hexagonal shape. The upper screw head 21 and the lower screw thread 22 each have an intermediate hollow portion 23 through which a conduit passes. In order to ensure the strength of the screw when being screwed, the diameter of the hollow part 23 is slightly larger than the diameter of the pipeline, as long as the use requirement can be met, namely, the pipeline can be ensured to pass through smoothly without being too large. It should be understood that the shape, size, etc. of the screw can be set according to the actual situation, and it is only necessary to ensure that the screw is screwed up by matching with the threaded hole. And are not intended as limitations on the present application.

As shown in fig. 2, the curved carrier 3, in this embodiment a conical ferrule. The material may be rubber or other elastic material. And is not intended as a limitation on the present embodiment. As shown in fig. 2 and 3, the curved carrier includes an upper annular flat surface 31, a lower annular flat surface 32, a middle curved solid portion 33, and a middle hollow portion 34 through which a pipeline can pass. The outer diameter of the bottom annular plane 32 is matched with the threaded hole 1 in an engineering mode, namely the bottom annular plane can be inserted into the threaded hole and meets the tolerance matching requirement.

As shown in fig. 2, the diameter of the upper annular plane 31 is smaller than that of the bottom annular plane 32, and the larger the size difference is, the larger the cone inclination angle is, the larger the effect of holding the pipeline tightly is. The upper annular flat surface 31 and the bottom annular flat surface 32 are connected together by the side of the vertebral body to form a curved solid portion 33. The hollow portions 34 allow the conduits to pass therethrough and mate with one another.

It is noted that by "matching" is meant here that the central hollow portion of the curved support has a diameter slightly larger than the diameter of the pipe, just enough to pass the pipe, but not much larger. Thus, the pipeline can pass through and be clamped tightly, and the pipeline is prevented from moving in the horizontal direction. When the external thread of the lower thread 22 and the internal middle thread 13 of the threaded hole 1 are screwed together, the bottom annular flat surface 32 contacts the bottom 11 of the threaded hole 1, so that the pipeline is fixed in the vertical direction. Wherein a cone height of 3.5mm is preferred (cone height is related to thread gauge, here 1/4-28UNF threads for example). Further, the choice of material, size and shape of the curved bearing are not intended to limit the present embodiment, as long as it is ensured that when the screw is tightened, a pressure directed to the pipeline can be generated. And is not intended as a limitation on the present embodiment.

It should be noted that the fixing structure may be disposed on the bottle cap, and a plurality of fixing structures may be disposed on one bottle cap. As shown in fig. 2, the closure is provided with a raised portion 4, either above or below the plane of the closure. The boss portion 4 includes the threaded hole 1 and a cutout portion 41. The number of the threaded holes 1 can be one or more than one according to actual needs. The dug portions 41, which are located between the screw holes 1, are provided for saving the raw material of the bottle cap. The bottle cap material can be plastic, metal material and the like.

Fig. 3 is a force diagram of the pipe when the pipe is fixed in the first embodiment. As shown in fig. 3, when fixing a pipe, the lower end of the pipe is sequentially passed through the hollow portion 23 of the hollow screw 2 and the hollow portion 34 of the curved carrier 3, and then the hollow screw 2 is screwed into the threaded hole 1, and the curved carrier bottom 32 is pressed against the threaded hole bottom 11. The downward pressure generated by screwing the screw and the thread can enable the curved surface bearing object to generate inward force, so that the curved surface bearing object is tightened, and the pipeline is fixed.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present application and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
