DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0024] like Figure 1-5 As shown, according to one aspect of the present invention, a food inspection sample storage device with a classification function is provided, comprising two shells 1, test tube racks 2 are slidably connected inside the two shells 1, an inner cavity 3 is provided inside the test tube rack 2, and a plurality of test tube grooves 4 are provided on the outer surface of the test tube rack 2. The shells 1 shield and protect the test tube grooves 4 and the test tubes, thereby improving the safety of the test tubes and preventing the test tubes from contacting the outside. A bottom groove 5 is provided below the outer surface of the test tube rack 2, and a lifting frame 6 is slidably connected inside the bottom groove 5. The lower sides of the two shells 1 and the left and right ends of the lifting frame 6 are all arc-shaped structures. When the shells 1 are opened and the lifting frame 6 slides down, when the person closes and closes the shells 1, the arc surface at the bottom of the shells 1 will press against the arc surfaces at the left and right ends of the lifting frame 6, so that the lifting frame 6 rises and resets.

[0025] An inner groove 7 is provided on the upper surface of the lifting frame 6, a rotating shaft 8 is rotatably connected inside the inner cavity 3, a plurality of claw plates 9 are fixed on the outer surface of the rotating shaft 8, a plurality of guide grooves 10 are penetrated inside the claw plate 9, a guide rod 11 is movably connected inside the guide groove 10, the left end of the guide rod 11 is located on the left side of the claw plate 9 and a support plate 12 is fixed, the end of the support plate 12 away from the rotating shaft 8 is located inside the test tube groove 4, and a piston 13 is fixed, a plurality of gears 14 are fixed on the outer surface of the rotating shaft 8, a tooth plate 15 is meshed and connected with the rear end of the gear 14, the bottom end of the tooth plate 15 penetrates into the inner groove 7, and is fixedly connected to the lower surface of the inner groove 7, and the lower surface of the inner groove 7 is connected to the bottom groove A plurality of springs 16 are fixed between the inner upper surfaces of the guide groove 10 and the inner wall of the guide groove 10. When the two housings 1 are opened to the left and right, the lifting frame 6 which loses the limit will push the spring 16 downward to drive the tooth plate 15 to move downward. The tooth plate 15 makes the gear 14 drive the rotating shaft 8 and the claw plate 9 to rotate. When the guide groove 10 rotates with the claw plate 9, the inner wall of the guide groove 10 will push the guide rod 11 inside to slide along the inside, and push the piston 13 to slide inside the test tube groove 4 through the support plate 12, so that the top of the test tube filled with the sample placed inside the test tube groove 4 is pushed out of the test tube groove 4. All the test tubes inside the test tube groove 4 are displayed simultaneously, which is convenient for personnel to quickly check, select and take;

[0026] The inner diameters of the front and rear adjacent test tube slots 4 are different. The test tube slots 4 are adapted to the pistons 13 located therein. The diameter of the pistons 13 is the same as the inner diameter of the corresponding test tube slots 4, forming a sliding connection relationship. Test tube slots 4 of different sizes are used to store test tubes of different diameters, so that food inspection samples of different volumes can be classified and stored.

[0027] Handles 22 are fixed to the opposite sides of the two casings 1 , and the casings 1 on both sides can be easily pulled apart by operating the handles 22 .

[0028] like Figure 4-5 As shown, the tooth plate 15 is slidably connected to the test tube rack 2, and a plurality of tooth grooves are provided on the front surface of the tooth plate 15. The tooth plate 15 is meshed with the gear 14 through the tooth grooves. Under the rotation of the gear 14, the tooth plate 15 drives the lifting frame 6 to slide up and down.

[0029] like Figure 3 As shown, slideways 17 are provided below the inner side walls of the two shells 1, and a slider 18 is slidably connected inside the slideway 17. The top of the slider 18 is fixedly connected to the bottom of the lower surface of the test tube rack 2. Under the limitation of the slideway 17 and the slider 18, the shell 1 can only move horizontally left and right along the outer surface of the test tube rack 2, but cannot rotate. Under the limitation of the slideway 17 with a limited distance, the shell 1 cannot slide too much, avoiding the separation of the shell 1 and the test tube rack 2, making the structure integrated and convenient for storage and movement.

[0030] like Figure 2 As shown, a screw rod 19 is connected through the upper part of the interior of the casing 1 on the right side, and a screw hole 20 is opened on the upper right side of the casing 1 on the left side. The left end of the screw rod 19 is threadedly connected with the inner part of the screw hole 20. The right end of the screw rod 19 is located on the right side of the casing 1 on the right side and is fixed with an operating block 21. When the operating block 21 is passed, the screw rod 19 rotates and disengages from the screw hole 20, thereby releasing the connection between the two casings 1, and then the casing 1 can be opened to expose the test tube rack 2, and operations such as storing and taking out test tubes can be performed.

[0031] like Figure 1-2 As shown, two rollers 23 are rotatably connected to the lower part of the outer surface of the casing 1, and the two rollers 23 are symmetrically arranged front to back. When the casing 1 is pulled left to right, the rollers 23 assist its movement to prevent the casing 1 from contacting the desktop or the ground and scratching the casing 1 or the desktop; positioning blocks 24 are rotatably connected to the lower parts of the two opposite ends of the casing 1, and the bottom ends of the positioning blocks 24 are made of rubber. The rubber positioning blocks 24 increase resistance when in contact with the desktop, thereby playing a braking effect, thereby preventing the casing 1 from accidentally sliding under the action of the rollers 23. When the casing 1 needs to be opened, the positioning blocks 24 are rotated so that they are no longer in contact with the desktop.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
