Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling bottle technology; more specifically, it relates to a sampling bottle. Background Technology
[0002] Food sampling is a crucial step in food safety supervision, quality testing, and scientific research. Its purpose is to extract representative samples from a large number of food products. Through the testing and analysis of these samples, information such as the quality, safety status, and nutritional composition of the entire batch of food can be accurately inferred. Food sampling bottles are containers specifically used for collecting, storing, and transporting food samples, playing a key role in food safety testing and quality monitoring.
[0003] Currently, existing sampling bottles suffer from several drawbacks during use. These bottles may experience shaking or collisions during handling and transportation, causing solid food samples to move within the bottle, leading to surface wear, breakage, or changes in shape. This reduces the practicality of the equipment. Furthermore, when collecting multiple samples of the same food from different locations or of different types using existing sampling bottles, the lack of separators allows samples to mix and become difficult to distinguish, affecting the accurate analysis of individual samples and further reducing the equipment's usability. Therefore, a new sampling bottle is urgently needed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sampling bottle to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a sampling bottle, comprising:
[0006] The box body has an internal barrier structure and a positioning structure, and an adjustment structure at the top.
[0007] The barrier structure includes a first bottle neck thread, a connecting post, and a second bottle neck thread, and the first bottle neck thread is fixedly connected to the upper surface of the box.
[0008] The positioning structure includes a positioning plate and a fixing plate, and the positioning plate is provided in multiple sets, with a movable column fixedly connected to one end of the positioning plate;
[0009] The adjustment structure includes a threaded cap, and the bottom surface of the threaded cap is threadedly connected to the outer surface of the second bottle neck thread.
[0010] Preferably, the barrier structure further includes a connecting post, and the upper surface of the first bottle neck thread is threadedly connected to the inner wall surface of the lower end of the connecting post. The upper surface of the connecting post is fixedly connected to the bottom surface of the second bottle neck thread. A first partition plate is fixedly connected inside the box, and a rubber pad is provided on the bottom surface inside the first partition plate. This design allows food samples to be placed inside the first partition plate.
[0011] Preferably, a sleeve is fitted on the outer surface of the lower end of the movable column, and a fixing plate is fixedly connected to the bottom surface of the sleeve. A return spring is fitted on the outer surface of the movable column and the sleeve. The external dimensions of the fixing plate are adapted to the internal dimensions of the first partition plate. The two ends of the return spring abut against the bottom surface of the threaded cover and the upper surface of the fixing plate, respectively. This design allows the sleeve to move along with the fixing plate when the fixing plate moves.
[0012] Preferably, the bottom of the movable column is provided with a limiting ring, and the outer dimensions of the limiting ring are adapted to the inner dimensions of the sleeve. This design makes the sleeve more stable when moving on the outer surface of the movable column and can prevent the movable column from detaching from the inside of the sleeve.
[0013] Preferably, the adjustment structure further includes a placement groove, which is located inside the outer surface of the upper end of the threaded cover. Multiple sets of placement grooves are provided, and multiple sets of movable columns are respectively inserted into the interior of the multiple sets of placement grooves. A support column is fixedly connected to the center of the outer surface of the upper end of the threaded cover, and a positioning hole is provided on the outer side of the outer surface of the upper end of the support column. Multiple sets of positioning holes are provided, and the external dimensions of the positioning plate are adapted to the internal dimensions of the positioning hole. The positions of the multiple sets of positioning plates correspond to the positions of the multiple sets of positioning holes. A second partition plate is fixedly connected to the bottom surface of the threaded cover, and the external dimensions of the fixed plate are adapted to the internal dimensions of the second partition plate. This design allows the fixed plate to move within the second partition plate.
[0014] Preferably, the inner surface of the outer surfaces on both sides of the threaded cover is provided with T-shaped sliding grooves, and T-shaped sliding blocks are engaged with the inner surfaces of both sets of T-shaped sliding grooves. A positioning block is fixedly connected to one end of the T-shaped sliding block, and a positioning threaded post is threadedly connected to the inner surface of the positioning block. Positioning screw holes are provided on the inner wall surfaces of the upper and lower ends of the T-shaped sliding groove, and the inner surface of the positioning screw holes is adapted to the outer surface of one end of the positioning threaded post. Insertion grooves are provided on the inner surfaces of the outer surfaces on both sides of the connecting post, and the inner dimensions of the insertion grooves are adapted to the outer dimensions of the T-shaped sliding block. This design allows the T-shaped sliding block to move inside the T-shaped sliding grooves and insertion grooves, and the movement is more stable.
[0015] The technical effects and advantages of this utility model are as follows: By pulling the moving column upward, the outer surface of the positioning plate is disengaged from the inside of the positioning hole. By rotating the positioning plate to face the opposite direction, the return spring, due to its own elasticity, drives the positioning plate to return to the inside of the corresponding placement slot. This allows the fixing plate at the corresponding position to abut against the upper end of the sampling item, thereby completing the positioning of the sampling item. This makes it difficult for solid food samples to move inside the bottle, avoiding surface wear, breakage, or changes in shape, and to a certain extent, improving the practicality of the equipment.
[0016] By rotating the threaded cap, the bottom surface of the threaded cap is threadedly connected to the outer surface of the second bottle neck thread. Then, by rotating the box body, the outer surface of the first bottle neck thread is threadedly connected to the inner wall surface of the lower end of the connecting column. At this time, the position of the second partition plate will correspond to the position of the first partition plate, thus completing the separation of space. This prevents samples from contacting and mixing with each other inside the bottle and does not affect the accurate analysis of individual samples. This improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sampling bottle involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Example 1
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment proposes a sampling bottle, including:
[0026] Box 1, with a barrier structure 2 inside the box 1, a positioning structure 3 inside the box 1, and an adjustment structure 4 at the top of the box 1.
[0027] The barrier structure 2 includes a first bottle neck thread 21, a connecting post 22 and a second bottle neck thread 23, and the first bottle neck thread 21 is fixedly connected to the upper surface of the box body 1.
[0028] The positioning structure 3 includes a positioning plate 31 and a fixing plate 34, and the positioning plate 31 is provided in multiple sets, and a movable column 32 is fixedly connected to one end of the positioning plate 31.
[0029] The barrier structure 2 also includes a connecting post 22, and the upper surface of the first bottle mouth thread 21 is threadedly connected to the inner wall surface of the lower end of the connecting post 22. The upper surface of the connecting post 22 is fixedly connected to the bottom surface of the second bottle mouth thread 23. The box body 1 is fixedly connected to a first partition plate 24, and the bottom surface of the first partition plate 24 is provided with a rubber pad. This design can place the sampling item by the elasticity of the rubber pad material itself. During sample transportation, the rubber pad can buffer and unload the external force on the equipment to avoid wear on the sampling item.
[0030] A sleeve 33 is fitted onto the outer surface of the lower end of the movable column 32, and a fixing plate 34 is fixedly connected to the bottom surface of the sleeve 33. A return spring 35 is fitted onto the outer surfaces of the movable column 32 and the sleeve 33. The external dimensions of the fixing plate 34 are adapted to the internal dimensions of the first partition plate 24. The two ends of the return spring 35 abut against the bottom surface of the threaded cap 41 and the upper surface of the fixing plate 34, respectively. A limiting ring is provided at the bottom of the movable column 32, and the external dimensions of the limiting ring are adapted to the internal dimensions of the sleeve 33. This design allows the movable column 32 to move inside the sleeve 33 when the positioning plate 31 is pulled upward. When the fixing plate 34 at the bottom of the sleeve 33 contacts the sample, the sleeve 33 moves upward and is supported by the elasticity of the return spring 35. This ensures that the bottom surface of the fixing plate 34 is always against the upper surface of the sample. At the same time, the elasticity of the return spring 35 can buffer and relieve the external force on the equipment.
[0031] Example 2
[0032] like Figure 2 , Figure 3 and Figure 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0033] The adjustment structure 4 includes a threaded cap 41, the bottom surface of which is threadedly connected to the outer surface of the second bottle neck thread 23. The adjustment structure 4 also includes a placement groove 42, which is located inside the upper outer surface of the threaded cap 41. Multiple sets of placement grooves 42 are provided, and multiple sets of movable columns 32 are respectively inserted into the interior of the multiple sets of placement grooves 42. A support column 43 is fixedly connected to the center of the upper outer surface of the threaded cap 41, and a positioning hole 44 is provided on the outer side of the upper outer surface of the support column 43. Multiple sets of positioning holes 44 are provided, and the external dimensions of the positioning plate 31 correspond to the internal dimensions of the positioning holes 44. The dimensions of the parts are compatible, and the positions of the multiple sets of positioning plates 31 correspond to the positions of the multiple sets of positioning holes 44 respectively. The bottom surface of the threaded cover 41 is fixedly connected to the second partition plate 45, and the external dimensions of the fixing plate 34 are compatible with the internal dimensions of the second partition plate 45. This design allows the outer surface of the positioning plate 31 to be inserted into the inside of the positioning hole 44, so that the position of the positioning plate 31 can be positioned through the positioning hole 44. When the fixing plate 34 moves downward, the second partition plate 45 will prevent the fixing plate 34 from deflecting when it moves, so that the fixing plate 34 can better position the sampling item.
[0034] The threaded cover 41 has T-shaped sliding grooves 46 on the inner surface of its two outer sides, and T-shaped sliding blocks 47 are engaged with the inner surfaces of both sets of T-shaped sliding grooves 46. A positioning block 48 is fixedly connected to one end of each T-shaped sliding block 47, and a positioning threaded post 49 is threadedly connected to the inner surface of the positioning block 48. Positioning screw holes are formed on the inner wall surfaces of the upper and lower ends of the T-shaped sliding grooves 46, and the inner surfaces of these positioning screw holes are adapted to the outer surfaces of one end of the positioning threaded post 49. Insertion grooves are formed on the inner surface of the outer surfaces of both sides of the connecting post 22, and the inner dimensions of these insertion grooves are adapted to the outer dimensions of the T-shaped sliding block 47. This design allows the threaded cover 41 to engage with the second... After the bottle neck thread 23 is threaded, the positioning threaded post 49 can be rotated so that the outer surface of the positioning threaded post 49 is disengaged from the inside of the positioning screw hole. At this time, the positioning block 48 can be moved downward. When the positioning block 48 can no longer be moved, the outer surface of the T-shaped sliding block 47 is simultaneously inserted into the inside of the T-shaped sliding groove 46 and the insertion groove, so that the position of the first partition plate 24 corresponds to the position of the second partition plate 45. The positioning threaded post 49 is rotated again so that the outer surface of the positioning threaded post 49 is re-threaded into the inside of the positioning screw hole at the corresponding position. At this time, the fixing of the threaded cap 41 and the connecting post 22 at the connection position is completed.
[0035] Working principle: When using the device, first place the box 1 in a suitable position, then connect the bottom thread of the connecting post 22 to the outer surface of the first bottle mouth thread 21 on the upper surface of the box 1. At this time, the sampling items can be placed inside the first partition plate 24 in a suitable position. Then rotate the threaded cover 41 to connect its thread to the outer surface of the second bottle mouth thread 23. When the position of the T-shaped sliding groove 46 corresponds to the position of the insertion groove, the position of the first partition plate 24 corresponds to the position of the second partition plate 45. At this time, move the positioning block 48 downward so that the lower end of the T-shaped sliding block 47 is inserted into the insertion groove. Then rotate the positioning thread post 49 so that the outer surface of the positioning thread post 49 is threaded into the positioning screw hole at the corresponding position. This completes the connection between the threaded cap 41 and the connecting post 22. Then, pull one end of the moving post 32 at the corresponding position upward, so that the positioning plate 31 is disengaged from the interior of the positioning hole 44 at the corresponding position. At this time, the moving post 32 will move the positioning plate 31 into the interior of the placement slot 42 by its own elasticity due to the return spring 35. At the same time, the fixing plate 34 will apply pressure to position the sampled item. When it is necessary to remove the sampled item, pull the moving post 32 at the corresponding position to move into the interior of the positioning hole 44, so that the fixing plate 34 no longer applies pressure to the sampled item. Then rotate the box body 1 so that the first bottle neck thread 21 is no longer threaded to the bottom surface of the connecting post 22, thereby facilitating the removal of the sampled item. The above is the entire working principle of this utility model.
