Abstract
Description
Technical Field
[0001] This utility model relates to the field of food testing technology, specifically to a food testing sample placement rack. Background Technology
[0002] Testing food samples is an important means of ensuring food safety, protecting public health, maintaining market order, and promoting the healthy development of the food industry. By testing food, various harmful contaminants, such as microorganisms and pesticide residues, can be detected in a timely manner, preventing substandard food from entering the market.
[0003] Before, during, and after testing, these samples need to be properly placed and preserved. Samples are typically placed in test tubes, which are then placed on test tube racks. Most existing test tube racks have factory-set orifice diameters, suitable only for test tubes of a specific diameter. However, testing often requires various sizes of test tubes. Since the orifice size is fixed and not adjustable, multiple sizes of test tube racks are needed, increasing testing costs. Utility Model Content
[0004] (I) Technical problems to be solved The technical problem to be solved by this utility model is to overcome the defect that the placement hole size of the above-mentioned test tube rack is not adjustable and cannot fix test tubes of different sizes, and to provide a food testing sample placement rack.
[0005] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a food testing sample placement rack, including a storage box, in which multiple storage chambers are equidistantly arranged, and a pull-out rack is provided in each storage chamber. The rack has a U-shaped structure and a horizontal plate is provided on the rack. Multiple placement holes are equidistantly opened on the horizontal plate, and a fixing component is connected to the placement holes. The fixing component includes two symmetrically arranged adjusting plates. Vertical plates are symmetrically arranged on one side of the placement holes on the horizontal plate. A bidirectional screw is rotatably connected between the two vertical plates. One end of the bidirectional screw extends to one side of one of the vertical plates and is connected to a knob. A connecting plate is connected to the adjusting plate, and one end of the connecting plate is threadedly connected to the bidirectional screw. A clamping plate is connected to the adjusting plate by multiple springs.
[0006] As an improvement: the frame has four sections, and the clamping plates and adjusting plates are all arc-shaped plate structures, with rubber pads glued to the inner side of the clamping plates.
[0007] As an improvement: symmetrical limit grooves are provided on the horizontal plate below the bidirectional lead screw, and a limit block is connected to the bottom surface of the connecting plate, with the limit block slidingly disposed in the limit groove.
[0008] As an improvement: a water receiving chamber is provided below the storage chamber in the storage box, and a water inlet channel communicating with the water receiving chamber is provided at the bottom of the storage chamber. The water inlet channel has a V-shaped structure, and a water receiving box is pulled out of the water receiving chamber.
[0009] As an improvement: sliding grooves are provided on the inner walls of both sides of the storage chamber, and a slider is provided on one side plate of the frame. The slider has a 45° chamfered corner structure and slides in the sliding groove.
[0010] As an improvement: a vertical plate is connected to the bottom surface of the horizontal plate between the two placement holes.
[0011] (III) Beneficial Effects The advantages of this utility model compared with the prior art are as follows: By setting up the fixing components, the bidirectional lead screw can drive the clamps on both sides to change the spacing, thereby fixing and clamping test tubes of different sizes, improving the applicability of the frame. Furthermore, the design of the clamps connected by springs can more accurately match the size of the test tubes, provide a more stable clamping force, and prevent excessive clamping force from damaging the test tubes, thus improving the safety of clamping and fixing. Multiple independently set storage rooms can be used to store different samples in categories, which not only facilitates later retrieval but also reduces cross-contamination between different samples, thereby ensuring the accuracy of subsequent testing.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0015] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0016] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0017] Combined with appendix Figures 1 to 3 As shown, a food testing sample storage rack includes a storage box 1 with multiple storage chambers 2 evenly spaced within it. These independent chambers allow for the categorized storage of different types of samples. Each storage chamber 2 contains a retractable shelf 3 with a U-shaped structure. Slide grooves 18 are formed on the inner walls of both sides of each storage chamber 2. A slider 19 with a 45° chamfered corner is mounted on one side plate of the shelf 3 and slides within the slide grooves 18. The interaction between the slider 19 and the slide grooves 18 restricts the movement of the shelf 3, preventing damage to test tubes due to excessive force causing it to detach. The chamfered slider 19 facilitates easy insertion into the slide grooves 18.
[0018] Combined with appendix Figures 3 to 5 As shown, there are four frames 3 in total. The frames 3 are provided with horizontal plates 4. Three placement holes 5 are equally spaced on the horizontal plates 4. Fixing components are connected to the placement holes 5. The fixing components include two symmetrically arranged adjusting plates 6. Vertical plates 7 are symmetrically arranged on one side of the placement holes 5 on the horizontal plates 4. A two-way screw 8 is rotatably connected between the two vertical plates 7. One end of the two-way screw 8 extends to one side of one of the vertical plates 7 and is connected to a knob 9. A connecting plate 10 is connected to the adjusting plate 6. One end of the connecting plate 10 is threaded to the two-way screw 8. A clamping plate 12 is connected to the adjusting plate 6 by multiple springs 11. Both the clamping plate 12 and the adjusting plate 6 are arc-shaped plate structures, and a rubber pad 13 is glued to the inner side of the clamping plate 12. To prevent the connecting plate 10 from rotating with the double-acting lead screw 8, combined with the attached... Figure 4 and Figure 5 As shown, a limiting groove 14 is symmetrically opened on the horizontal plate 4 below the bidirectional lead screw 8. A limiting block 15 is connected to the bottom surface of the connecting plate 10. The limiting block 15 is slidably disposed in the limiting groove 14. With the cooperation of the limiting groove 14 and the limiting block 15, the displacement trajectory of the connecting plate 10 is restricted, so that it can only move horizontally along the limiting groove 14.
[0019] When the test tube is inserted into the placement hole 5, the knob 9 is turned and the two-way screw 8 rotates clockwise, which drives the adjusting plates 6 on both sides to move towards the center of the test tube, tightly clamping the sample test tube placed in the placement hole 5. The arc-shaped clamping plate 12 can better fit test tubes of different sizes. The rubber pad 13 increases the friction between the two, making the fixation more stable and reducing the risk of the test tube falling off. Moreover, the spring 11 can play a certain buffering role to avoid damage to the test tube caused by excessive clamping.
[0020] Combined with appendix Figure 2 and Figure 3 As shown, a water receiving chamber is provided below the storage chamber 2 inside the storage box 1. A water inlet trough 16 communicating with the water receiving chamber is provided at the bottom of the storage chamber 2. The water inlet trough 16 has a V-shaped structure. A water receiving box 17 is pulled out inside the water receiving chamber. A vertical plate 20 is connected between the two placement holes 5 on the bottom surface of the horizontal plate 4. The vertical plate 20 can isolate different test tubes and prevent cross-contamination.
[0021] When a test tube breaks and causes sample leakage, or when the test tube is cleaned and placed upside down on the rack 3 to dry, the liquid can enter the water collection box 17 through the V-shaped water inlet 16. When it is necessary to clean up the leaked material or liquid, simply pull out the water collection box 17 for processing, which facilitates the operator's operation and cleaning.
[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
