Description

Technical Field

[0001] This application relates to the field of food inspection technology, specifically to a sample storage device for food inspection and testing. Background Technology

[0002] Food inspection, broadly speaking, refers to the discipline of studying and evaluating food quality and its changes. Based on fundamental theories of physics, chemistry, and biochemistry, and various techniques, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products according to established technical standards, such as international and national food hygiene / safety standards, to ensure product quality compliance. The content of food inspection includes sensory testing of food, detection of nutritional components, additives, and harmful substances. Sample storage equipment is needed in food inspection to facilitate the placement and transportation of collected samples.

[0003] Patent CN221893587U discloses a sample storage device for food testing. This device uses a moving rod to move a support plate and a limiting plate upwards, facilitating the placement and retrieval of test tubes and improving operational convenience. A fixing screw on the mounting plate of the housing, in conjunction with a fixing nut on the mounting plate, provides a stable connection and fixation between the cover and the housing. However, in actual use, this device is prone to damage in the event of collisions or contact with external objects, causing the lifting knob to rotate and samples to detach from their fixed positions. This provides space for sample movement, increasing the possibility of damage from collisions between test tubes and reducing the safety of sample storage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sample storage device for food inspection and testing, which solves the problems mentioned in the background section.

[0005] Technical solution

[0006] To achieve the above objectives, this application provides the following technical solution: a sample storage device for food inspection and testing, comprising a base plate, a fixing cover for preventing external collisions from damaging the sample, and a fixing mechanism for fixing the fixing cover in place. The base plate is provided with adjustment mechanisms on both the left and right sides of the top, which facilitate the disassembly and assembly of the fixing cover. The adjustment mechanism includes a flipping groove and a rotating plate. The flipping groove is opened on the left and right sides of the top of the base plate, and the front and rear sides of the rotating plate are rotatably connected to the inner wall of the flipping groove. The fixing cover is disposed above the base plate, and the fixing mechanism is fixedly connected to one side of the adjustment mechanism.

[0007] By adopting the above technical solution, the rotating plate in the flipping groove can be used to prevent external objects from moving the trapezoidal block without human intervention, thus preventing the fixing cover from becoming loose.

[0008] Preferably, the adjustment mechanism further includes a movable cavity and a trapezoidal block, the movable cavity being formed at the bottom of the flip groove, and the bottom of the trapezoidal block being slidably connected to the bottom of the movable cavity.

[0009] By adopting the above technical solution, the movable cavity can provide space for the movement of the trapezoidal block, and avoid the possibility of accidental collisions to the installation structure, thus ensuring the stability of the installation structure.

[0010] Preferably, the fixing mechanism includes a fixing groove and an L-shaped plate. The fixing groove is located on the lower part of the inner wall of the left and right sides of the fixing cover, and the L-shaped plate is slidably connected to the fixing groove.

[0011] By adopting the above technical solution, the L-shaped plate can be inserted into the fixing groove to achieve the purpose of fixing the position of the fixing cover.

[0012] Preferably, the fixing mechanism further includes a telescopic tube and a spring. The telescopic tube is fixedly connected to one side of the L-shaped plate, and one end of the telescopic tube is fixedly connected to one side of the inner wall of the movable cavity. The spring is located outside the telescopic tube, and the spring is fixedly connected to one side of the L-shaped plate. One end of the spring is fixedly connected to one side of the inner wall of the movable cavity.

[0013] By adopting the above technical solution, the movement direction of the trapezoidal block can be guided by the telescopic tube, and the spring force itself can be used to provide support for the L-shaped plate.

[0014] Preferably, the fixing mechanism further includes a movable groove and a connecting plate. The movable groove is opened on one side of the top of the movable cavity. The movable groove is slidably connected to the side of the L-shaped plate. The connecting plate is fixedly connected to the other side of the L-shaped plate. One side of the connecting plate is fixedly connected to one side of the trapezoidal block.

[0015] By adopting the above technical solution, the movable slot can be used to provide space for the movement of the L-shaped plate, and the direction of movement of the L-shaped plate can be restricted to ensure the accuracy of the movement path of the L-shaped plate.

[0016] Preferably, the top of the connecting plate is fixedly connected to a limiting mechanism for restricting the position of the trapezoidal block. The limiting mechanism includes a support column and a limiting groove. The bottom of the support column is fixedly connected to the top of the connecting plate, and a rubber ball is fixedly connected to the top of the support column. The limiting groove is opened on the other side of the top of the movable cavity, and the inner wall of the limiting groove is in contact with the surface of the rubber ball.

[0017] By adopting the above technical solution, the position of the trapezoidal block can be restricted by the fit between the rubber ball at the top of the support column and the inner wall of the limiting groove, thus preventing the fixing cover from detaching from the fixing.

[0018] Preferably, the top surface of the base plate is uniformly provided with placement holes for placing samples.

[0019] By adopting the above technical solution, the placement holes can be used to facilitate the equidistant placement of samples, reducing the possibility of samples colliding with each other due to being too close.

[0020] Preferably, the bottom of the fixed cover has cooling cavities on both the front and rear sides for placing ice packs.

[0021] By adopting the above technical solution, ice packs in the cooling chamber can be used to delay the deterioration time of the sample and ensure the accuracy of the sample test data. Beneficial effects

[0022] This application provides a sample storage device for food inspection and testing. It has the following beneficial effects:

[0023] 1. This food inspection and testing sample storage equipment, through the setting of an adjustment mechanism, applies force to the rotating plate in the tilting groove by adjusting the rod, causing the rotating plate to rotate. The adjusting rod moves down to the trapezoidal block in the movable cavity, squeezing it to one side, which facilitates the bottom of the fixing cover to fit with the top of the base plate. This avoids the situation where the fixing cover detaches from the base plate during use, reduces the possibility of test tubes colliding with each other under the influence of external forces and causing damage, ensures the stability of sample storage, and improves the safety of sample storage.

[0024] 2. This food inspection and testing sample storage device, by setting a limiting mechanism, moves the support column, which in turn moves the rubber ball. The rubber ball moves until its surface is in contact with the inner wall of the limiting groove, reducing the possibility of the support column being displaced by accidental impact, enhancing the stability of the installation structure, and further enhancing the safety of the samples stored in the device.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a sample storage device for food inspection and testing, including a base plate 1, a fixing cover 2 for preventing external collisions from damaging the sample, and a fixing mechanism 4 for fixing the fixing cover 2 in place. The left and right sides of the top of the base plate 1 are provided with adjustment mechanisms 3 for easy disassembly and assembly of the fixing cover 2. The adjustment mechanism 3 includes a flip groove 301 and a rotating plate 302. The flip groove 301 is opened on the left and right sides of the top of the base plate 1. The front and rear sides of the rotating plate 302 are rotatably connected to the inner wall of the flip groove 301. The bottom of the flip groove 301 is provided with a movable cavity 303. A trapezoidal block 304 is slidably connected to the bottom of the movable cavity 303. The fixing cover 2 is set above the base plate 1. The fixing mechanism 4 is fixedly connected to one side of the adjustment mechanism 3. When the adjustment rod is applied to the rotating plate 302 in the flip groove 301, the rotating plate 302 is rotated. The adjustment rod moves down to the trapezoidal block 304 in the movable cavity 303 and squeezes it to one side.

[0036] Reference Figure 1 , Figure 2 Figure 5 and Figure 6 In one aspect of this embodiment, the fixing mechanism 4 includes a fixing groove 401 and an L-shaped plate 402. The fixing groove 401 is formed below the inner walls of the left and right sides of the fixing cover 2. The L-shaped plate 402 is slidably connected to the fixing groove 401. A telescopic tube 405 is fixedly connected to one side of the L-shaped plate 402. One end of the telescopic tube 405 is fixedly connected to one side of the inner wall of the movable cavity 303. A spring 406 is provided on the outside of the telescopic tube 405. The spring 406 is fixedly connected to one side of the L-shaped plate 402. One end of the spring 406 is fixed to the inner wall of the movable cavity 303. One side is fixedly connected, and a movable groove 403 is opened on one side of the top of the movable cavity 303. The movable groove 403 is slidably connected to the side of the L-shaped plate 402. A connecting plate 404 is fixedly connected to the other side of the L-shaped plate 402. One side of the connecting plate 404 is fixedly connected to one side of the trapezoidal block 304. The spring 406 itself has elastic force to drive the telescopic tube 405 connected to the L-shaped plate 402 on one side of the connecting plate 404 to extend. The extension of the telescopic tube 405 drives the L-shaped plate 402 in the movable groove 403 to be inserted into the fixed groove 401, thus fixing the fixed cover 2 in place.

[0037] Reference Figure 5 and Figure 6 In one aspect of this embodiment, a limiting mechanism 5 for restricting the position of the trapezoidal block 304 is fixedly connected to the top of the connecting plate 404. The limiting mechanism 5 includes a support column 501 and a limiting groove 503. The bottom of the support column 501 is fixedly connected to the top of the connecting plate 404, and a rubber ball 502 is fixedly connected to the top of the support column 501. The limiting groove 503 is opened on the other side of the top of the movable cavity 303. The inner wall of the limiting groove 503 is in contact with the surface of the rubber ball 502. The movement of the support column 501 causes the rubber ball 502 to move, and the rubber ball 502 moves until its surface is in contact with the inner wall of the limiting groove 503.

[0038] Reference Figure 1 and Figure 3 In one aspect of this embodiment, the top surface of the base plate 1 is uniformly provided with placement holes 101 for placing samples, and test tubes containing samples are sequentially placed into the placement holes 101.

[0039] Reference Figure 2 and Figure 5 In one aspect of this embodiment, the bottom front and rear sides of the fixed cover 2 are provided with cooling cavities 201 for placing ice packs, and the ice packs are placed into the cooling cavities 201.

[0040] All electrical devices in this plan are powered by an external power source.

[0041] Working principle: In use, place the test tubes containing the samples into the placement holes 101 one by one, put the ice pack into the cooling chamber 201, apply force to the rotating plate 302 in the flipping groove 301 to make the rotating plate 302 rotate, and move the adjusting rod down to the trapezoidal block 304 in the movable chamber 303 to squeeze it to one side. The movement of the trapezoidal block 304 causes the L-shaped plate 402 on one side of the connecting plate 404 to move. Place the fixing cover 2 on the surface of the base plate 1, remove the adjusting rod, and the rotating plate 302 rotates to be parallel to the surface of the base plate 1. The spring 406 itself... The elastic force causes the telescopic tube 405, which is connected to the L-shaped plate 402 on one side of the connecting plate 404, to extend. The extension of the telescopic tube 405 causes the L-shaped plate 402 in the moving groove 403 to be inserted into the fixing groove 401, thus fixing the fixing cover 2. The movement of the L-shaped plate 402 causes the support column 501 at the top of the connecting plate 404 to move. The movement of the support column 501 causes the rubber ball 502 to move. The rubber ball 502 moves until its surface is in contact with the inner wall of the limiting groove 503. At the same time, the movement of the connecting plate 404 causes the trapezoidal block 304 to move to one side of the movable cavity 303.
