Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and more specifically, to a nuclear radiation sample storage device. Background Technology

[0002] In some locations, such as hospitals, isotopes are used for imaging diagnosis and treatment during procedures. Patients who ingest or inject radioactive isotopes during these processes excrete radioactive wastewater, which requires treatment before discharge to avoid adverse environmental impacts. In existing technologies, radioactive wastewater is typically collected in a pool, and then distributed for treatment using multiple pools. During treatment, samples are taken from the same pool or different pools to assess the treatment effect. Current technologies employ nuclear radiation sample storage devices to obtain nuclear radiation samples from different pools at different times. These devices include a housing and multiple sample bottles placed inside the housing; each sample bottle is used independently.

[0003] The inventors discovered in their research that existing nuclear radiation sample storage devices have at least the following drawbacks:

[0004] The sample bottles are used independently. Since the sample bottles are all inserted into the box, it is impossible to determine which sample bottles have been used. Furthermore, in order to obtain multiple samples, all sample bottles are exposed after the box is opened, which poses a safety hazard such as slipping. Utility Model Content

[0005] The purpose of this invention includes, for example, providing a nuclear radiation sample storage device that can intuitively obtain the usage status of sample bottles, and that sample bottles that have completed sample collection are not easily slipped off during repeated opening of the box lid, thus ensuring high safety.

[0006] The embodiments of this utility model can be implemented as follows:

[0007] In a first aspect, this utility model provides a nuclear radiation sample storage device, comprising:

[0008] The storage box comprises a box lid, multiple sample bottles, and multiple positioning mechanisms. The storage box is provided with multiple positioning grooves, and the multiple positioning grooves, the multiple sample bottles, and the multiple positioning mechanisms are respectively matched one-to-one. The sample bottles can be detachably inserted into the corresponding positioning grooves. The box lid is movably connected to the storage box and is used to open or close the multiple positioning grooves.

[0009] Each of the positioning mechanisms includes a positioning seat, a positioning post, and a first elastic element. The positioning seat is fixed to the box cover. The positioning post is optionally and detachably connected to the positioning seat and the positioning groove. The first elastic element is fixed to the positioning post. The positioning post is used to connect to the positioning groove after being detached from the positioning seat, and to make the first elastic element contact the corresponding sample bottle.

[0010] In an optional embodiment, the storage box includes a body and an elastic enclosure. The plurality of positioning grooves are all provided on the body. The elastic enclosure is connected to the body and protrudes from the top side of the body. The plurality of positioning grooves are all located within the area enclosed by the elastic enclosure.

[0011] Based on the above solution, by setting elastic baffles around the body, the sample bottles can be protected and prevented from slipping off the body. They can also block impurities, making it difficult for external impurities to enter the area where the sample bottles are located.

[0012] In an optional embodiment, the storage box further includes an annular buckle that is fitted onto the body.

[0013] Based on the above solution, the use of an inverted ring makes it easier to connect with the lid.

[0014] In an optional embodiment, the lid includes a lid body, a limiting plate, and a snap-fit ​​assembly. The lid body is provided with a mounting groove, and the positioning seat is fixed to the bottom wall of the mounting groove. The limiting plate is fixed to the peripheral wall of the mounting groove. The snap-fit ​​assembly includes a mounting lug, a buckle, and a torsion spring. The mounting lug is fixed to the outside of the lid body, the buckle is rotatably connected to the mounting lug, and the torsion spring is sleeved on the outside of the buckle's pivot. The two ends of the torsion spring are respectively connected to the buckle and the mounting lug. The torsion spring is used to make the buckle tend to rotate closer to the lid body. The limiting plate is used to abut against the elastic retaining plate, and the buckle is used to engage with the annular snap-fit.

[0015] Based on the above solution, when it is necessary to connect the lid to the storage box, the elastic panel is inserted into the positioning groove, with the end of the elastic panel contacting the limiting plate. Then, the buckle is rotated to engage with the annular snap fastener. Due to the large distribution area of ​​the annular snap fastener, the engagement between the buckle and the snap fastener is more convenient and reliable. Because the elastic panel has a certain elastic deformation capacity, when the buckle and the snap fastener engage, the elastic panel deforms and presses against the limiting plate, ensuring a firm and reliable connection between the lid and the storage box, preventing it from easily loosening.

[0016] In an optional embodiment, the number of snap-fit ​​components is multiple and they are arranged at intervals in the circumferential direction of the cover.

[0017] Based on the above solution, multiple snap-fit ​​components are used in conjunction with the ring buckle, resulting in more connection points and a more secure and reliable connection.

[0018] In an optional implementation, the positioning post may be selectively screwed into the positioning seat and the positioning groove.

[0019] Based on the above solution, the positioning column and the positioning seat or positioning groove are connected by screws, which is convenient to operate and the connection is firm and reliable.

[0020] In an optional embodiment, the positioning seat is provided with a threaded hole; a portion of the positioning groove is configured as a threaded hole segment; the positioning post is provided with a first external threaded groove and a second external threaded groove, the first external threaded groove being used to screw into the threaded hole, and the second external threaded groove being used to screw into the threaded hole segment.

[0021] Based on the above scheme, the positioning post is machined with a first external thread groove and a second external thread groove arranged at intervals. It is not necessary to machine the entire outer circumferential surface of the positioning post with external thread grooves, which reduces the machining difficulty, reduces material consumption, and reduces the machining and manufacturing cost.

[0022] In an optional embodiment, an operating rod is provided on the outer peripheral surface of the positioning post, and the operating rod is located between the first external thread groove and the second external thread groove.

[0023] Based on the above scheme, by rotating the operating lever, it is easy to apply force, thereby facilitating the rotation of the positioning column and making it easier to assemble and disassemble the positioning column from the positioning seat and the positioning groove.

[0024] In an optional embodiment, the nuclear radiation sample storage device further includes a second elastic element installed in the positioning groove. The second elastic element is used to make the sample bottle tend to move toward the opening of the positioning groove, and to make the top of the sample bottle extend out of the opening of the positioning groove.

[0025] Based on the above solution, when the box lid is opened, the second elastic element can push the unused sample bottle out from the slot of the positioning groove, which makes it easier for the operator to pick up the sample bottle, reduces the difficulty of operation, and improves the efficiency of operation.

[0026] In an optional embodiment, a handle is provided on the top of the lid.

[0027] Based on the above solution, when moving the storage device, the handle is less likely to slip, making it easier to operate.

[0028] The beneficial effects of this utility model embodiment include, for example:

[0029] In summary, the nuclear radiation sample storage device provided in this embodiment places multiple sample vials in multiple positioning grooves, with each groove holding one sample vial. Furthermore, used sample vials are connected to the positioning grooves via positioning posts and locked in place. When the lid is opened, used sample vials are not directly exposed and are further restrained by the positioning posts, preventing them from detaching from the grooves. This not only allows the operator to visually assess the usage status of the sample vials but also improves the safety of sample vial use, reduces the risk of damage to sample vials containing nuclear radiation samples, and lowers the risk of radioactive material leakage.

[0030] It should be understood that, due to the radioactivity of nuclear radiation samples, nuclear radiation sample storage devices can be manufactured using special materials, such as lead, stainless steel, concrete, epoxy resin, and tungsten alloys, to ensure their safety, reliability, and durability. Provided that safety is met, the storage box, lid, multiple sample vials, and multiple positioning mechanisms can all be made of one of the aforementioned materials, selected as needed; specific details are not provided in this embodiment.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0042] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0044] In existing technology, multiple sample bottles 300 are placed in a dedicated box. The sample bottles 300 can also be made of special materials to meet safety requirements. Multiple sample bottles 300 are inserted into the box, and each sample bottle 300 can be freely removed and placed out of the box. During sample collection, multiple sample bottles 300 are needed to obtain multiple samples. This involves repeatedly opening and closing the box opening. When the opening is open, all sample bottles 300 are exposed, making it difficult to visually assess their usage status. Furthermore, since the sample bottles 300 are not properly positioned, they can easily detach from the box, posing a safety hazard.

[0045] In view of this, the designers have provided a nuclear radiation sample storage device that can intuitively obtain the usage status of the sample vial 300, and the sample vial 300 after collection will not be directly exposed to the external environment, making it safe and reliable.

[0046] Please combine Figures 1-4 The nuclear radiation sample storage device includes a storage box 100, a box cover 200, multiple sample bottles 300, and multiple positioning mechanisms 400. The storage box 100 is provided with multiple positioning grooves 101, and the multiple positioning grooves 101, multiple sample bottles 300, and multiple positioning mechanisms 400 are respectively matched one-to-one. The sample bottles 300 can be detachably inserted into the corresponding positioning grooves 101. The box cover 200 is movably connected to the storage box 100 and is used to open or close the multiple positioning grooves 101. Each positioning mechanism 400 includes a positioning seat 410, a positioning post 420, and a first elastic element 430. The positioning seat 410 is fixed to the box cover 200. The positioning post 420 is optionally and detachably connected to the positioning seat 410 and the positioning groove 101. The first elastic element 430 is fixed to the positioning post 420. The positioning post 420 is used to connect to the positioning groove 101 after being detached from the positioning seat 410, and to make the first elastic element 430 contact the corresponding sample bottle 300, thereby preventing the sample bottle 300 from coming out of the groove of the positioning groove 101.

[0047] As described above, the nuclear radiation sample storage device provided in this embodiment is used as follows:

[0048] Please combine Figure 3 and Figure 4 Multiple sample vials 300 are placed in multiple positioning grooves 101, with each groove 101 positioning one sample vial 300. Furthermore, used sample vials 300 are connected to and locked in the positioning grooves 101 via positioning posts 420. When the lid 200 is opened, used sample vials 300 are not directly exposed and are further restrained by the positioning posts 420, preventing them from detaching from the grooves 101. This allows operators to easily monitor the usage status of the sample vials 300, improves the safety of their use, reduces the risk of damage to sample vials 300 containing nuclear radiation samples, and lowers the risk of radioactive material leakage.

[0049] It should be understood that the sample bottle 300 is limited in the positioning groove 101 by the first elastic element 430. The first elastic element 430 can provide stable elastic force and has a shock absorption effect, so the sample bottle 300 is not easily damaged by collision and is safe and reliable to use.

[0050] Please combine Figure 3In this embodiment, optionally, the storage box 100 includes a body 110 and an elastic enclosure 120. Multiple positioning grooves 101 are provided on the body 110, and the elastic enclosure 120 is connected to the body 110 and protrudes from the top side of the body 110. The multiple positioning grooves 101 are all located within the area enclosed by the elastic enclosure 120. By providing the elastic enclosure 120 around the body 110, it not only protects the sample bottle 300 and prevents it from slipping off the body 110, but also shields it from impurities, making it difficult for external impurities to enter the area where the sample bottle 300 is located.

[0051] It should be understood that a portion of the elastic panel 120 can be made of elastic material, or the elastic panel 120 can be made directly of elastic material.

[0052] It is worth noting that the body 110 can be a rectangular structure, and six positioning grooves 101 can be provided on the body 110. Correspondingly, there are six positioning mechanisms 400, and each positioning mechanism 400 cooperates with the corresponding positioning groove 101.

[0053] In this embodiment, optionally, the storage box 100 further includes an annular buckle 130, which is sleeved on the outside of the main body 110. By providing the annular buckle 130, it is convenient to connect with the box cover 200.

[0054] It should be understood that in other embodiments, instead of providing annular undercuts 130 around the body 110, multiple block-shaped undercuts may be provided. The number of undercuts can be selected as needed, as long as they can match the structure on the lid 200.

[0055] In this embodiment, optionally, the lid 200 includes a lid body 210, a limiting plate 220, and a snap-fit ​​assembly. The lid body 210 is provided with a mounting groove, and the positioning seat 410 is fixed to the bottom wall of the mounting groove. The limiting plate 220 is fixed to the peripheral wall of the mounting groove; the snap-fit ​​assembly includes a mounting lug 230, a buckle 240, and a torsion spring (not shown). The mounting lug 230 is fixed to the outside of the lid body 210, the buckle 240 is rotatably connected to the mounting lug 230, and the torsion spring is sleeved on the outside of the rotating shaft of the buckle 240. The two ends of the torsion spring are respectively connected to the buckle 240 and the mounting lug 230; the torsion spring is used to make the buckle 240 have a tendency to rotate closer to the lid body 210; the limiting plate 220 is used to abut against the elastic surrounding plate 120, and the buckle 240 is used to snap into the annular buckle 130.

[0056] It should be understood that when it is necessary to connect the lid 200 to the storage box 100, the elastic baffle 120 is inserted into the positioning groove 101, with the end of the elastic baffle 120 contacting the limiting plate 220. Then, the buckle 240 is rotated to engage with the annular buckle 130. Due to the large distribution area of ​​the annular buckle 130, the engagement between the buckle 240 and the annular buckle 130 is more convenient and reliable. Because the elastic baffle 120 has a certain elastic deformation capacity, when the buckle 240 and the buckle engage, the elastic baffle 120 deforms and abuts against the limiting plate 220, ensuring a firm and reliable connection between the lid 200 and the storage box 100, preventing it from easily coming loose.

[0057] It should be noted that, because the buckle 240 tends to rotate closer to the cover 210 under the action of the torsion spring, after the buckle 240 and the annular buckle 130 are engaged, the buckle 240 is always locked with the annular buckle 130, which is not easy to loosen and is safe and reliable to use.

[0058] In this embodiment, optionally, the number of snap-fit ​​components is multiple and they are arranged at intervals around the circumference of the cover 210. By having multiple snap-fit ​​components cooperate with the annular buckle 130, there are more connection points, and the connection is firm and reliable.

[0059] In this embodiment, optionally, the positioning post 420 can be screwed into the positioning seat 410 and the positioning groove 101. The positioning post 420 is screwed into the positioning seat 410 or the positioning groove 101, which is convenient to operate and provides a firm and reliable connection.

[0060] Optionally, the positioning seat 410 is provided with a threaded hole. A portion of the positioning groove 101 is configured as a threaded hole section. The positioning post 420 is provided with a first external threaded groove and a second external threaded groove, the first external threaded groove being used for screwing into the threaded hole, and the second external threaded groove being used for screwing into the threaded hole section.

[0061] It should be understood that the positioning post 420 has a first external thread groove and a second external thread groove arranged at intervals. It is not necessary to machine the entire outer circumferential surface of the positioning post 420 with external thread grooves, which reduces the processing difficulty, reduces material consumption, and reduces processing and manufacturing costs.

[0062] In this embodiment, optionally, an operating rod 440 is provided on the outer peripheral surface of the positioning post 420, and the operating rod 440 is located between the first external thread groove and the second external thread groove. By rotating the operating rod 440, it is easy to apply force, thereby facilitating the rotation of the positioning post 420, which is beneficial for the assembly and disassembly of the positioning post 420 from the positioning seat 410 and the positioning groove 101.

[0063] There can be multiple operating levers 440, which facilitates the application of force.

[0064] In this embodiment, optionally, the nuclear radiation sample storage device further includes a second elastic element 500. The second elastic element 500 is installed in the positioning groove 101. The second elastic element 500 is used to make the sample bottle 300 tend to move towards the opening of the positioning groove 101, and to make the top of the sample bottle 300 extend out of the opening of the positioning groove 101. When the lid 200 is opened, the second elastic element 500 can push the unused sample bottle 300 out from the opening of the positioning groove 101, thereby making it easier for the operator to pick up the sample bottle 300, reducing the difficulty of operation and improving the efficiency of operation.

[0065] In this embodiment, optionally, a handle 600 is provided on the top of the lid 200. When moving the storage device, the handle 600 is less likely to slip, making operation easier.

[0066] It should be understood that both the first elastic element 430 and the second elastic element 500 can be configured as springs.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
