Description

Technical Field

[0001] This utility model relates to the field of storage container technology, and in particular to a water sample storage container. Background Technology

[0002] After water samples are collected, they generally need to be placed in containers and then sent to the laboratory for subsequent testing. Current technologies typically use containers with inlets for loading and unloading water samples, which is convenient and quick. However, these containers are generally rigid structures with a fixed large volume, capable of holding water samples smaller than their maximum capacity. Even when used to hold small volumes (e.g., a container with a maximum capacity of 500ml holding 100ml of water), they still occupy considerable space. The number of water samples is also usually large (e.g., 20 100ml samples), requiring them to be placed in transport devices (e.g., storage boxes). Even with a relatively small total volume of water samples, the large number of containers still results in significant space waste. Existing technologies can use flexible containers instead. Because these containers can deform, a 500ml total volume can be used to hold 100ml of water, limiting the container size and saving considerable space. However, during loading and unloading, pressure differences between the inside and outside of the container can cause obstructions and inconvenience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a water sample storage container that solves the problem of poor flow when loading and unloading water samples in existing flexible containers.

[0004] According to an embodiment of this utility model, a water sample storage container includes a container body, which comprises a flexible bag body and an upper mounting plate and a lower mounting ring fixedly connected to both ends of the flexible bag body. An inlet pipe and a balancing pipe communicating with the flexible bag body are fixedly connected to the upper mounting plate, and an outlet pipe communicating with the flexible bag body is fixedly connected to the lower mounting ring. The inlet pipe, outlet pipe, and balancing pipe are detachably connected to a first cover, a second cover, and a third cover, respectively. The inlet pipe and outlet pipe are provided for water sample entry and exit, respectively. The balancing pipe allows for communication between the container body and the outside environment during water sample loading and unloading, maintaining pressure balance. Therefore, water sample loading and unloading can proceed smoothly, solving the problem of obstructed loading and unloading of water samples in existing flexible containers.

[0005] Furthermore, the first cover, the second cover, and the third cover are respectively provided with a first elastic element, a second elastic element, and a third elastic element to prevent the flexible bag from communicating with the outside.

[0006] Furthermore, a stop ring is fixedly connected to the balance tube, and a movable ring is provided between the stop ring and the container body, which surrounds the balance tube. A pull rope is fixedly connected between the movable ring and the first cover.

[0007] Furthermore, a support ring is fixedly connected to the inner wall of the inlet pipe, a support ring is provided on the support ring, and a filter screen cylinder that passes downward through the support ring is fixedly connected to the support ring.

[0008] Furthermore, a first elastic ring is fixedly connected to the top surface of the support ring, and the first elastic ring can elastically abut against the inner wall of the inlet pipe.

[0009] Furthermore, a pull rod is fixedly connected to the inner wall of the support ring.

[0010] Furthermore, the first elastic element includes a second elastic ring fixedly connected to the top surface of the first cover body. The second elastic ring can elastically abut against the inner wall of the inlet pipe, and the pull rod is located below the second elastic ring or partially accommodated within the second elastic ring.

[0011] Furthermore, the second elastic element includes a first elastic head that is fixedly connected to the top surface of the second cover body, and the first elastic head can elastically abut against the inner wall of the outlet pipe.

[0012] Furthermore, the third elastic element includes a second elastic head that is fixedly connected to the top surface of the third cover body, and the second elastic head can elastically abut against the inner wall of the balance tube.

[0013] Furthermore, the first cover, the second cover, and the third cover are all threadedly connected to the inlet pipe, the outlet pipe, and the balance pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The balancing tube allows the container to be connected to the outside environment, ensuring pressure balance between the inside and outside of the container when filling and emptying water samples. This ensures smooth filling and emptying of water samples, solving the problem of obstructed filling and emptying of water samples in existing flexible containers. Furthermore, when filling a smaller volume of water sample, the balancing tube and inlet tube allow for faster air expulsion from the container, facilitating compression of the flexible bag. Then, the first and third covers are closed, and the flexible bag is folded, reducing the space occupied. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] In an exemplary implementation, such as Figure 1-5As shown, this embodiment provides a water sample storage container, which includes a container body 1. The container body 1 includes a flexible bag body 2 and an upper mounting plate 3 and a lower mounting ring 4 fixedly connected to both ends of the flexible bag body 2. An inlet pipe 5 and a balance pipe 6 communicating with the flexible bag body 2 are also fixedly connected to the upper mounting plate 3. An outlet pipe 7 communicating with the flexible bag body 2 is also fixedly connected to the lower mounting ring 4. The upper mounting plate 3 and the lower mounting ring 4 provide a base for fixed connection of the inlet pipe 5, the balance pipe 6 and the outlet pipe 7, respectively. Furthermore, the inlet pipe 5, the outlet pipe 7 and the balance pipe 6 are detachably connected to a first cover 8, a second cover 9 and a third cover 10, respectively. When water sample is loaded, the second cover 9 closes the outlet pipe 7, and the first cover 8 and the third cover 10 are removed. At this time, the balance pipe 6 allows the flexible bag body 2 to be in communication with the outside, thereby ensuring that the water sample smoothly enters the flexible bag body 2 through the inlet pipe 5. When water sample is poured out, the first cover 8 closes the inlet pipe 5, and the third cover 10 and the second cover 10 are removed. When body 9 is removed, the balance tube 6 also serves to connect the inside and outside of the flexible bag body 2. The water sample can be smoothly poured out through the outlet tube 7. That is, when water samples are being loaded and poured out, the balance tube 6 allows the inside of the container body 1 to be connected to the outside world, and the air pressure inside and outside the container body 1 is balanced. Therefore, the loading and unloading of water samples can be carried out smoothly, solving the problem of obstruction when loading and unloading water samples in the existing technology. Furthermore, in this solution, the first cover 8, the second cover 9, and the third cover 10 are respectively provided with a first elastic element, a second elastic element, and a third elastic element to prevent the flexible bag body 2 from being connected to the outside world. That is, the first elastic element, the second elastic element, and the third elastic element seal the flexible bag body 2 to prevent water sample leakage. More specifically, the first cover 8, the second cover 9, and the third cover 10 are all threadedly connected to the inlet tube 5, the outlet tube 7, and the balance tube 6, which allows for easy opening or closing of the corresponding inlet tube 5, outlet tube 7, or balance tube 6.

[0026] like Figure 1-5 As shown, a stop ring 11 is also fixedly connected to the balance tube 6. A movable ring 12 is also provided between the stop ring 11 and the container body 1, which surrounds the balance tube 6. A pull rope 13 is fixedly connected between the movable ring 12 and the first cover 8. The first cover 8 can be suspended by the pull rope 13 and is not easy to lose. The third cover 10 can also abut against the stop ring 11 to prevent over-tightening. Similarly, the inlet tube 5 and outlet tube 7 can also be provided with stop rings 11 to prevent over-tightening. At the same time, when the first cover 8 is closed, the pull rope 13 can act as a handle to facilitate lifting the container body 1.

[0027] like Figure 2 , 3As shown, a support ring 14 is fixedly connected to the inner wall of the inlet pipe 5. A support ring 15 is mounted on the support ring 14. A filter screen cylinder 16, which passes downward through the support ring 14, is fixedly connected to the support ring 15. The filter screen cylinder 16 has filter mesh holes 17 located below the support ring 14. In this way, the filter screen cylinder 16 can filter at the inlet pipe 5, preventing larger impurities from entering the flexible bag body 2. At the same time, the filter screen cylinder 16 can be removed for cleaning. Furthermore, a first elastic ring 18 is fixedly connected to the top surface of the support ring 15. The first elastic ring 18 can elastically abut against the inner wall of the inlet pipe 5. The support ring 14 supports the support ring 15, so that the filter screen cylinder 16 is in a relatively stable state, which can smoothly filter the water sample. The support ring 15 can maintain a large distance from the inlet pipe 5. The gap allows for smooth placement and removal of the filter cylinder 16. The first elastic ring 18 elastically abuts against the inlet pipe 5, making the support ring 15 more stable and preventing unfiltered water samples from entering the flexible bag body 2 through the gap between the support ring 15 and the inlet pipe 5, thus ensuring filtration effectiveness. More specifically, a pull rod 19 is fixedly connected to the inner wall of the support ring 15, allowing for easy removal of the filter cylinder 16 for cleaning. Furthermore, the first elastic element includes a second elastic ring 20 fixedly connected to the inner top surface of the first cover 8. The second elastic ring 20 elastically abuts against the inner wall of the inlet pipe 5 to provide a seal, while also providing space for the pull rod 19, meaning the pull rod 19 is located below the second elastic ring 20 or partially accommodated within the second elastic ring 20.

[0028] like Figure 2-5 As shown, the second elastic element includes a first elastic head 21 fixedly connected to the inner top surface of the second cover 9. The first elastic head 21 can elastically abut against the inner wall of the outlet pipe 7, that is, it plays a sealing role through the first elastic head 21. Similarly, the third elastic element includes a second elastic head 22 fixedly connected to the inner top surface of the third cover 10. The second elastic head 22 can elastically abut against the inner wall of the balance pipe 6, and it plays a sealing role through the second elastic head 22. More specifically, the first elastic ring 18, the second elastic ring 20, the first elastic head 21 and the second elastic head 22 can all be structures in which the contact surface (that is, the part that elastically abuts against the inlet pipe 5, the outlet pipe 7 and the balance pipe 6 respectively) is wrapped with elastic rubber. The inner layer of the elastic rubber is a material that is not easily deformed, such as hard plastic, to provide mechanical support. When the outer elastic rubber layer is tightened and loosened (or the filter screen cylinder 16 is pressed down and lifted), it ensures that the elastic abutment is successfully achieved, while avoiding excessive deformation that would lead to sealing failure.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
