Description

Technical Field

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

[0002] When conducting food inspection and testing, it is necessary to first sample the food, and then transport the sampled food to the laboratory for testing. Currently, most of the sampled food is placed directly in a storage box and then transported to the laboratory for testing.

[0003] According to Chinese Patent Publication No. CN218594924U, a sample storage device for food inspection and testing is disclosed. This device includes a test tube clamping plate, which is movably mounted between two guide grooves via guide rollers on both sides. The entire test tube clamping plate can extend and retract within the storage box. Rubber pads are installed inside the equidistantly arranged partition holes on the upper surface of the test tube clamping plate. When storing test tubes, the test tube clamping plate is pulled out of the storage box, and the test tubes are inserted into the corresponding partition holes. Because the rubber pads on the inner walls of the partition holes have strong deformation capabilities, when the test tubes are inserted, the rubber pads deform to fit the test tube walls, increasing the friction and preventing the test tubes from shaking after being fixed in the partition holes.

[0004] In the current technical solution, when personnel need to remove a food sample, they need to fully open the protective door of the storage box, which causes other food samples that do not need to be removed to come into large-scale contact with the external environment, potentially leading to contamination. Furthermore, during the process of removing a food sample, it may be necessary to pass by other food sample tubes, which may cause collisions and damage between the sample tubes, resulting in sample leakage and contamination of the storage box and the environment. Therefore, we propose a sample storage device for food inspection and testing. Utility Model Content

[0005] The purpose of this invention is to provide a sample storage device for food inspection and testing, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sample storage device for food inspection and testing, comprising a storage box, a chuck, and a support plate. A rotating shaft extends through the top of the storage box and is rotatably connected to the storage box via a bearing. The chuck is fixedly sleeved on the outer wall of the rotating shaft. The support plate has a shaft hole and is movably sleeved on the outer wall of the rotating shaft through the shaft hole. A support groove is formed at the top of the support plate. A limit hole is formed on the chuck. A threaded groove at the bottom of the rotating shaft is threadedly connected to a screw rod. A rotating plate is fixedly installed at the bottom of the screw rod. A connecting rod is fixedly installed at the top of the rotating plate. A support ring is fixedly installed at the top of the connecting rod and contacts the bottom of the support plate. A knob plate is fixedly installed at the top of the rotating shaft. A sampling port at the top of the storage box is hinged to a top cover. A serial number plate is fixedly installed on the outer wall of the support plate. A transparent window is embedded on one side of the storage box. A door is hinged to the front of the storage box.

[0007] Preferably, a limiting slide plate is fixedly installed on the inner wall of the shaft hole, and a limiting groove is opened at the bottom end of the rotating shaft. The limiting slide plate and the limiting groove are slidably connected. By setting the limiting slide plate and the limiting groove, the rotating shaft can drive the support plate to rotate through the limiting slide plate.

[0008] Preferably, there are several support grooves and limiting holes, and their positions are corresponding. Wall pads are fixedly installed on the inner walls of both the support grooves and limiting holes. The wall pads are made of wear-resistant rubber. By setting the wall pads, the food sample tubes can be protected to a certain extent, reducing wear and improving the stability of the food sample tubes when placed.

[0009] Preferably, a limiting ring is fixedly sleeved on the outer wall of the rotating shaft. There are two limiting rings, which are symmetrically arranged inside and outside the top of the storage box. A ball bearing is movably embedded on the opposite surface of the two limiting rings. A rolling groove is opened on the inner and outer sides of the top of the storage box. The ball bearing is in rolling connection with the rolling groove. By setting the limiting ring, the rotating shaft can be limited. Furthermore, by setting the ball bearing, the friction between the limiting ring and the storage box can be reduced, thereby improving the flexibility of the rotating shaft.

[0010] Preferably, the outer wall of the knob plate has a slot, and the top of the storage box has a moving groove. An L-shaped locking rod is slidably connected in the moving groove, and the L-shaped locking rod is engaged in the slot. A limiting rod is fixedly installed on the inner wall of the moving groove. The limiting rod moves through the L-shaped locking rod, and a spring surrounds the outer wall of the limiting rod. The spring is fixedly installed between the outer wall of the L-shaped locking rod and the inner wall of the moving groove. By setting up the L-shaped locking rod, the slot, the moving groove, the limiting rod, and the spring together, the knob plate can be limited and fixed, thereby improving the stability of the support plate for the food sample test tubes during use.

[0011] Preferably, an ice pack box is fixedly installed on the back of the storage box, and ice packs can be placed in the ice pack box to cool the inside of the storage box.

[0012] This invention provides a sample storage device for food inspection and testing. This sample storage device for food inspection and testing has the following beneficial effects:

[0013] (1) The food inspection and testing sample storage equipment can facilitate the safe and convenient removal of a single food sample by personnel, reduce the contact between other food samples and the outside world, ensure the preservation effect of the storage box on the food sample, and solve the problem that in the existing technical solution, when personnel need to remove a food sample, they need to fully open the protective door of the storage box, which will cause other food samples that do not need to be removed to come into contact with the outside environment on a large scale, which may lead to contamination. In addition, when removing a food sample, it may be necessary to pass by other food sample tubes, and the sample tubes may collide and be damaged, resulting in sample leakage, which will contaminate the storage box and the environment.

[0014] (2) The food inspection and testing sample storage device can limit and fix the knob plate by setting up an L-shaped clamp, a clamping groove, a moving groove, a limiting rod and a spring, thereby improving the stability of the support plate for the food sample tube during use. It has a simple structure and strong practicality. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6As shown, this utility model provides a technical solution: a sample storage device for food inspection and testing, including a storage box 1, a chuck 3, and a support plate 4. A rotating shaft 2 passes through the top of the storage box 1, and the rotating shaft 2 is rotatably connected to the storage box 1 through a bearing. The chuck 3 is fixedly sleeved on the outer wall of the rotating shaft 2. The support plate 4 has a shaft hole 15, and the support plate 4 is movably sleeved on the outer wall of the rotating shaft 2 through the shaft hole 15. A support groove 5 is formed at the top of the support plate 4. A limit hole 6 is formed on the chuck 3, and a threaded groove is formed at the bottom of the rotating shaft 2. A screw 10 is threadedly connected, a rotating plate 12 is fixedly installed at the bottom of the screw 10, a connecting rod 13 is fixedly installed at the top of the rotating plate 12, a support ring 14 is fixedly installed at the top of the connecting rod 13, the support ring 14 is in contact with the bottom of the support plate 4, a knob plate 18 is fixedly installed at the top of the rotating shaft 2, a top cover 11 is hinged to the sampling port at the top of the storage box 1, an orderly number plate 16 is fixedly installed on the outer wall of the support plate 4, a transparent window 17 is inlaid on one side of the storage box 1, and a door 28 is hinged to the front of the storage box 1.

[0026] Specifically, in the above technical solution, when using the food inspection and testing sample storage equipment, various food sample tubes are placed in the support groove 5, and the corresponding serial number coordinates of various food samples are recorded by the serial number plate 16. The support plate 4 is then inserted from below the rotating shaft 2, so that the food sample tubes are inserted into the limiting hole 6 on the chuck 3, and the limiting slide plate 8 slides into the limiting groove 9. The limiting slide plate 8 slides to the top of the limiting groove 9, and then the support ring 14 is inserted from the bottom of the rotating shaft 2. Then, the rotating plate 12 is rotated, so that the rotating plate 12 drives the screw 1. 0. The rotating shaft 2 is inserted into the threaded groove at its bottom, allowing the support ring 14 to support and limit the support plate 4, thus completing the storage of food samples. When a food sample needs to be removed individually, the L-shaped lever 20 can be pulled outward according to its serial number. The L-shaped lever 20 compresses the spring 23, and when it moves outward, it disengages from the slot 19 at its current position. Then, the knob plate 18 is rotated, causing the rotating shaft 2 to rotate. The rotating shaft 2, through the limiting slide plate 8, drives the support plate 4 to rotate. At this time, personnel can observe the support plate 4 through the transparent window 17. When the serial number plate 16 corresponding to the food sample is observed, the rotating plate 12 is stopped, the L-shaped locking lever 20 is released, and the L-shaped locking lever 20 is locked into the current position slot 19 under the reset force of the spring 23, limiting the knob plate 18 and thus fixing the support plate 4. Then, the top cover 11 of the storage box 1 can be opened, allowing personnel to directly take out the required food sample test tube from the sampling port opened at the top of the storage box 1. Through the above structure, it is convenient and safe for personnel to take out a single food sample, reducing the contact between other food samples and the outside world, ensuring the preservation effect of the storage box 1 on the food samples. This solves the problem in the existing technical solution that when personnel need to take out a food sample, they need to fully open the protective door of the storage box 1, which will cause other food samples that do not need to be taken out to come into contact with the outside environment over a large area, which may lead to contamination. In addition, during the process of taking out a food sample, it may be necessary to pass by other food sample test tubes, and the sample test tubes may collide and be damaged, leading to sample leakage, which will contaminate the storage box 1 and the environment.

[0027] Furthermore, a limiting slide plate 8 is fixedly installed on the inner wall of the shaft hole 15, and a limiting groove 9 is opened at the bottom end of the rotating shaft 2, with the limiting slide plate 8 and the limiting groove 9 slidably connected.

[0028] By setting a limiting slide plate 8 and a limiting slide groove 9, the rotating shaft 2 can drive the support plate 4 to rotate through the limiting slide plate 8.

[0029] Furthermore, there are several support grooves 5 and limiting holes 6, and their positions are corresponding. Wall pads 7 are fixedly installed on the inner walls of both support grooves 5 and limiting holes 6. The material of the wall pads 7 is wear-resistant rubber.

[0030] The wall pad 7 provides some protection for the food sample tubes, reduces wear, and improves their stability during placement.

[0031] Furthermore, a limiting ring 24 is fixedly sleeved on the outer wall of the rotating shaft 2. There are two limiting rings 24. The two limiting rings 24 are symmetrically arranged inside and outside the top of the storage box 1. Rolling balls 25 are movably embedded on the opposite surfaces of the two limiting rings 24. Rolling grooves 26 are opened inside and outside the top of the storage box 1. The rolling balls 25 are tumblingly connected to the rolling grooves 26.

[0032] The limiting ring 24 can limit the rotation of the shaft 2, and the ball bearing 25 can reduce the friction between the limiting ring 24 and the storage box 1, thereby improving the flexibility of the shaft 2 rotation.

[0033] Furthermore, the outer wall of the knob plate 18 is provided with a slot 19, and the top of the storage box 1 is provided with a moving slot 21. An L-shaped locking rod 20 is slidably connected in the moving slot 21. The L-shaped locking rod 20 is locked in the slot 19. A limiting rod 22 is fixedly installed on the inner wall of the moving slot 21. The limiting rod 22 moves through the L-shaped locking rod 20, and a spring 23 surrounds the outer wall of the limiting rod 22. The spring 23 is fixedly installed between the outer wall of the L-shaped locking rod 20 and the inner wall of the moving slot 21.

[0034] The knob plate 18 can be fixed by the combination of L-shaped locking rod 20, locking groove 19, moving groove 21, limiting rod 22 and spring 23, thereby improving the stability of the support plate 4 in supporting the food sample tube during use.

[0035] Furthermore, an ice pack box 27 is fixedly installed on the back of the storage box 1;

[0036] Ice packs can be placed in the ice pack box 27 to cool the inside of the storage box 1.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
