Description

Technical Field

[0001] The utility model belongs to the technical field of detection boxes, in particular to a sample storage box for detection. Background Art

[0002] With the continuous development of society, in order to improve food safety and protect the health of consumers, it is necessary to inspect food to analyze the auxiliary materials and additives in the food.

[0003] Currently, when testing personnel sample liquid food, they often place the sucked liquid food in a disposable test tube, then cover it, and then place the test tube in a test tube grid in a storage box. When collecting multiple samples, the test tube will be exposed to the outside for a long time, and the outside of the test tube will be contaminated. Therefore, when extracting the sample inside the test tube, it is easy to increase the risk of contamination due to touching the outside of the test tube. At the same time, during transportation, when the test tube cover is detached from the test tube due to bumps, it is easy to cause mutual contamination between the test tubes, thereby affecting the accuracy of the test. Utility Model Content

[0004] The utility model provides a sample storage box for detection, which is used to solve the defects in the prior art.

[0005] The utility model is achieved through the following technical solutions:

[0006] A sample storage box for testing includes a box body, wherein several cross beams are fixedly arranged in the box body, the cross beams are located at the upper part of the box body, screw holes are opened on the cross beams, an outer tube is threadedly connected to the screw holes, the lower end of the outer tube is closed and the upper end is threadedly connected to a tube cap, arc-shaped clamping plates are arranged on the side walls of the outer tube, and the clamping plates are supported by a first spring. The test tube is placed vertically in the outer tube and located between the two clamping plates.

[0007] When the present application is in use, the test tube from which the liquid sample has been extracted is placed in the outer tube and the test tube is clamped by the action of the clamping plate and the first spring, and then the tube cap is covered. Therefore, even if the storage box is exposed to the outside for a long time, the test tube in the outer tube will not be contaminated by the outside world. Furthermore, when extracting the liquid in the test tube, even if the outside of the test tube is touched, the probability of contamination will be very small. At the same time, even if the cover of the test tube falls off during transportation, it will only cause the liquid to fall into the outer tube, and will not cause contamination to other test tubes.

[0008] Preferably, a vertical tube is vertically connected to the inner wall of the top surface of the tube cap, and a vertical rod is slidably engaged within the vertical tube. The upper end of the vertical rod is fixedly connected to one end of a second spring, and the other end of the second spring is fixedly connected to the inner wall of the top surface of the tube cap. The lower end of the vertical inner rod is rotatably connected to a compression plate, and the bottom surface of the compression plate is fixedly connected to a shock-absorbing pad. The compression plate can compress the lid of the test tube under the action of the second spring, thereby ensuring that the lid does not fall off the test tube due to bumps during transportation, thereby better protecting the sample inside the test tube.

[0009] Preferably, the top surface of the extrusion plate is provided with an inverted T-shaped rotation groove, into which the rotation plate fits, and the top surface of the rotation plate is fixedly connected to the vertical inner rod. This allows the rotation plate to rotate within the rotation groove, and when the pipe cap is tightened, the extrusion plate does not rotate with the pipe cap, thereby achieving better extrusion.

[0010] Preferably, oppositely closed transverse tubes are fixedly embedded in the inner walls of both sides of the outer tube, and a transverse rod is slidably engaged within the transverse tubes. One end of the transverse rod is fixedly connected to one end of the first spring, the other end of the first spring is fixedly connected to the inner wall of the transverse tube, and the other end of the transverse rod is fixedly connected to the clamping plate. The cooperation between the transverse rod and the transverse tubes enables the clamping plate to exert positive pressure when clamping the test tube, thereby better clamping the test tube.

[0011] Preferably, a tapered tube, wider at the top and narrower at the bottom, is disposed below the outer tube. The inner wall of the tapered tube is lined with shock-absorbing cotton. One end of a support spring is fixedly connected to the bottom surface of the tapered tube, and the other end of the support spring is fixedly connected to the inner wall of the bottom surface of the outer tube. The tapered tube not only supports the outer tube but also acts as a limiter. Furthermore, the tapered structure of the tapered tube can accommodate test tubes of different sizes, increasing its applicability.

[0012] The beneficial effects of the present invention are as follows: the use of the present invention not only protects the test tube through the outer tube, preventing the test tube from being contaminated by the outside world, but also prevents the test tube from being damaged by external collisions. In addition, the use of the squeezing plate can squeeze the test tube cover, preventing the test tube cover from being separated from the test tube due to bumps during transportation, thereby further preventing the liquid in the test tube from being contaminated.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] A sample storage box for testing, such as Figure 1 and Figure 2 The apparatus comprises a box body 1, wherein a plurality of crossbeams 2 are fixedly installed in the box body 1. The crossbeams 2 are located at the upper portion of the box body 1. Screw holes are formed in the crossbeams 2, into which an outer tube 3 is threadedly connected. The lower end of the outer tube 3 is closed, and a tube cap 4 is threadedly connected to the upper end. Curved clamping plates 5 are provided on the side walls of the outer tube 3. The clamping plates 5 are supported by a first spring 6. The test tube is placed vertically in the outer tube 3 and between the two clamping plates 5.

[0020] When the present application is in use, the test tube from which the liquid sample has been extracted is placed in the outer tube 3 and the test tube is clamped by the clamping plate 5 and the first spring 6, and then the tube cap 4 is covered. Therefore, even if the storage box is exposed to the outside for a long time, the test tube in the outer tube 3 will not be contaminated by the outside world. When the liquid in the test tube is extracted, even if the outside of the test tube is touched, the probability of contamination will be very small. At the same time, even if the cover of the test tube falls off during transportation, it will only cause the liquid to fall into the outer tube 3, and will not cause contamination to other test tubes.

[0021] The inner walls of both sides of the outer tube 3 are fixedly inlaid with oppositely closed transverse tubes 14. A transverse rod 15 is slidably fitted within the transverse tube 14. One end of the transverse rod 15 is fixedly connected to one end of the first spring 6, the other end of the first spring 6 is fixedly connected to the inner wall of the transverse tube 14, and the other end of the transverse rod 15 is fixedly connected to the clamping plate 5. A vertical tube 7 is perpendicularly connected to the inner wall of the top surface of the tube cap 4. A vertical rod 8 is slidably fitted within the vertical tube 7. The upper end of the vertical rod 8 is fixedly connected to one end of the second spring 9, the other end of the second spring 9 is fixedly connected to the inner wall of the top surface of the tube cap 4. The lower end of the vertical inner rod is rotatably connected to the extrusion plate 10, and the bottom surface of the extrusion plate 10 is fixedly connected to a shock-absorbing pad 11.

[0022] The cooperation between the transverse rod 15 and the transverse tube 14 enables the clamping plate 5 to have opposite squeezing forces when clamping the test tube, thereby better clamping the test tube.

[0023] The squeezing plate 10, under the action of the second spring 9, can squeeze the test tube lid, thereby ensuring that the test tube lid will not fall off the test tube due to bumps during transportation, thereby better protecting the sample inside the test tube. The vertical tube 7 and the vertical rod 8 cooperate to ensure that the squeezing plate 10 squeezes the test tube lid in a positive direction without any tilting force, ensuring better squeezing of the lid.

[0024] The top surface of the extrusion plate 10 is provided with an inverted T-shaped rotation groove 12, into which a rotation plate 13 fits. The top surface of the rotation plate 13 is fixedly connected to the vertical inner rod. This allows the rotation plate 13 to rotate within the rotation groove 12. When the pipe cap 4 is tightened, the extrusion plate 10 does not rotate with the pipe cap 4, thereby achieving better extrusion.

[0025] The lower portion of the outer tube 3 is provided with a tapered tube 16, which is wider at the top and narrower at the bottom. The inner wall of the tapered tube 16 is lined with shock-absorbing cotton. One end of a support spring 17 is fixedly connected to the bottom surface of the tapered tube 16, and the other end of the support spring 17 is fixedly connected to the inner wall of the bottom surface of the outer tube 3. The tapered tube 16 not only provides shock absorption and support for the outer tube 3, but also acts as a limiter. The tapered structure of the tapered tube 16 can accommodate test tubes of different sizes, increasing its applicability.

[0026] The present invention not only protects the test tube through the outer tube 3, preventing the test tube from being contaminated by the outside world, but also prevents the test tube from being damaged by external collisions. In addition, the squeezing plate 10 can squeeze the test tube cap, preventing the test tube cap from being separated from the test tube due to bumps during transportation, thereby further preventing the liquid in the test tube from being contaminated.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
