Description

Technical Field

[0001] The invention belongs to the technical field of food detection, in particular to a sample storage device for food inspection with a classification function. Background Art

[0002] Food inspection refers to a discipline that studies and evaluates food quality and its changes. It is based on some basic theories and various techniques of physics, chemistry, and biochemistry. The content of food inspection includes sensory testing of food, testing of nutrients, additives, and harmful substances in food. The content of food inspection is very rich, including analysis of food nutrients, analysis of pollutants in food, analysis of food auxiliary materials and food additives, and food sensory identification.

[0003] First, when food needs to be inspected, the food samples to be inspected need to be placed in a food storage box and then transported to a testing agency for testing. However, most of the existing food storage boxes do not have sampling devices installed inside. When sampling is required, the testers take corresponding tableware or objects to sample the samples, and different sampling devices are required when taking liquid samples and solid samples, which consumes the working time of the testers and reduces the efficiency of the test. At the same time, if the sampling devices are not replaced, cross infection is likely to occur, thereby reducing the accuracy of sample testing. Therefore, a sample storage device for food inspection with a classification function is proposed. Summary of the invention

When sampling liquid samples and solid samples, different sampling devices need to be taken, which consumes the working time of the inspectors and reduces the efficiency of the inspection. At the same time, if the sampling device is not replaced, cross infection is likely to occur and the accuracy of sample inspection is reduced.

[0008] Preferably, the storage assembly also includes a classification rack installed on the bottom of the connecting block, a first spring fixed to the outside of the first protrusion, a fixing plate installed on the top of the first spring, a storage box arranged outside the classification rack, and a box door installed on the external front surface of the storage box.

[0009] Preferably, the rectangular plate slides horizontally inside the rectangular hole, and the bottom of the first spring telescopic rod is fixedly connected to the inner wall of the rectangular hole.

[0010] Preferably, the second protrusion matches the size of the extrusion block, and the bottom surface of the extrusion block contacts the top surface of the sample cover.

[0011] Preferably, a groove is provided inside the bottom of the first connecting block, the bottom of the third spring contacts the top surface of the second connecting block, and the top of the third spring contacts the top surface of the groove.

[0012] Preferably, the bottom of the pushing block is convex, and the bottom of the pushing block slides horizontally inside the rectangular hole.

[0013] Preferably, a plurality of holes are formed on the exterior of the sampler, and the exteriors of two adjacent samplers are in contact with each other.

[0014] Preferably, rectangular holes are formed on both sides of the exterior of the connection block, and the exterior of the first protrusion contacts the inner walls of the rectangular holes.

[0015] Preferably, the classification rack is in a cross shape, and there are multiple first springs that are evenly distributed on the bottom of the fixed plate.

[0016] Preferably, a handle is installed on the external front of the box door, a "C"-shaped block is provided on the top of the storage box, and a pulley is installed on the bottom of the storage box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention drives the clamping block to squeeze the outside of the airbag by pulling the pushing block. At the same time, after the airbag is forced to exhaust the internal air, the external air will be sucked from the bottom of the sampling tube due to the loss of the squeezing force, and the liquid sample will be sucked into the interior through the sampling tube. The filter block filters the sucked sample to prevent the sucked solid sample from entering the sampling tube. The sampling tube is used in coordination with the connecting round rod, the pushing block and the clamping block to improve the efficiency of sampling the liquid sample. At the same time, when the pushing block drives the clamping block to squeeze the airbag, the pushing block drives the first connecting block to rotate along the outside of the connecting round rod and the inside of the rectangular hole. The first connecting block squeezes the second spring telescopic rod and is compressed by force, so that the position of the first connecting block is deflected, and the angle of its upper end is adjusted. The first connecting block drives the second connecting block connected to the bottom to increase its angle, so that the sampler is expanded to both sides. When the push block is released, the second spring telescopic rod is reset to drive the first connecting block, the second connecting block, the third connecting block and the third spring to reset. The solid sample is clamped into the interior of the sampler by the third spring, so that the clamped liquid flows out through the hole. In this process, the speed of sampling food samples is improved, and the need to take different sampling devices for sampling liquid samples and solid samples is reduced, which increases the working time of the detection personnel and reduces the detection efficiency. At the same time, when the sampling device is replaced, cross infection is easily caused, and the accuracy of food sample data detection is improved.

[0019] The present invention enters the interior of the sample cover by rotating the sample can and puts the sample cover back on the top surface of the classification rack. At this time, the second protrusion is in a locked state with the limiting groove, and the second spring is in a compressed state. The staff pushes the rectangular plate to move horizontally along the interior of the rectangular hole and squeezes the first spring telescopic rod to be compressed. At the same time, the rectangular plate drives the second protrusion to disengage from the interior of the limiting groove, and the first protrusion is pushed downward by the second spring to move downward along the rectangular holes opened on both sides of the connecting block. At the same time, the first protrusion drives the externally installed extrusion block to move downward, so that the bottom surface of the extrusion block contacts the top surface of the sample can. When the food sample is transported, the sample can is reinforced by pressing the sample can with the extrusion block to prevent the bumps during transportation from causing the sample can to disengage from the interior of the sample cover and causing the sample to leak out.

[0020] The present invention contacts the bottom of the sample cover through the first spring, and is evenly distributed on the bottom of the first spring through multiple fixing plates. When bumps occur during transportation, the fixing plates effectively reduce shock to the sample cover, while preventing leakage of samples during transportation, thereby increasing the overall service life of the equipment.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, the present invention provides a sample storage device for food inspection with a classification function, comprising a storage component 1, a fixing component 2 installed inside the storage component 1, a sampling component 3 arranged at the bottom of the fixing component 2, a sample cover 5 connected to the outside of the sampling component 3, and a sample tank 4 threadedly connected to the inner side of the top of the sample cover 5;

[0032] The fixing assembly 2 also includes an extrusion block 204 disposed on the top surface of the sample tank 4, first protrusions 203 installed on both sides of the outside of the extrusion block 204, a second spring 202 fixedly connected to the top surface of the first protrusion 203, a connecting block 201 installed on the top of the second spring 202, a rectangular hole 206 disposed in the middle of the top surface of the connecting block 201, a rectangular plate 207 installed on the inner side of the rectangular hole 206, a second protrusion 208 fixedly mounted on the bottom of the rectangular plate 207, a first spring telescopic rod 209 connected to the outer side of the rectangular plate 207, and a limiting groove 205 disposed on the inner side of the extrusion block 204;

[0033] The sampling assembly 3 also includes a sampler 313 arranged inside the sample tank 4, a third connecting block 312 installed on both sides of the top end of the sampler 313, a second connecting block 311 fixedly connected to the inside of the third connecting block 312, a first connecting block 303 connected to the outside of the top of the second connecting block 311, a third spring 314 arranged inside the bottom of the first connecting block 303, a pushing block 309 installed on the outside of the top of the first connecting block 303, a clamping block 302 fixedly mounted on one end of the pushing block 309, an airbag 301 arranged on the inside of the outside of the clamping block 302, a sampling tube 315 fixedly connected to the bottom of the airbag 301, a filter block 316 arranged inside the bottom of the sampling tube 315, a second spring telescopic rod 304 connected to the inside of the outside of the first connecting block 303, a rectangular hole 305 and a rectangular hole 308 respectively arranged in the middle of the top surface of the sample cover 5, and a connecting round rod 310 installed on the inner wall of the rectangular hole 305.

[0034] The above scheme is adopted: by pushing the pushing block 309, the clamping block 302 is driven to squeeze the outside of the airbag 301. At the same time, after the airbag 301 is forced to exhaust the internal air, the external air will be sucked in from the bottom of the sampling tube 315 due to the loss of the squeezing force, and the liquid sample is sucked into the inside through the sampling tube 315. The inhaled sample is filtered by the filter block 316 installed inside the bottom of the sampling tube 315 to prevent the inhaled solid sample from entering the sampling tube 315. When the pushing block 309 drives the clamping block 302 to squeeze the airbag 301, the pushing block 309 drives the first connecting The connecting block 303 rotates along the outside of the connecting round rod 310 and the inside of the rectangular hole 305. The first connecting block 303 squeezes the second spring telescopic rod 304 and is compressed, so that the position of the first connecting block 303 is deflected. At this time, the angle of the upper end of the first connecting block 303 becomes smaller. At the same time, the first connecting block 303 drives the angle of the second connecting block 311 connected to the bottom to become larger. The third connecting block 312 and the sampler 313 are driven to expand to both sides through the second connecting block 311. When the staff releases the pushing block 309, the second spring telescopic rod 304 is reset. At the same time, the first connecting block 303, the second connecting block 311, the third connecting block 312 and the third spring 314 are driven to reset, and the solid sample is clamped into the interior of the sampler 313 through the third spring 314. The sampler 313 is provided with a plurality of holes on the outside so that the clamped liquid flows out through the holes. The staff puts the taken liquid sample and solid sample into the sample cover 5, rotates the sample tank 4 into the interior of the sample cover 5, and puts the sample cover 5 back on the top surface of the classification rack 103. At this time, the second protrusion 208 and the limiting groove 205 are in a locked state, and the first protrusion 208 and the limiting groove 205 are in a locked state. The second spring 202 is in a compressed state, and the staff pushes the rectangular plate 207 to move horizontally along the inside of the rectangular hole 206 and squeeze the first spring telescopic rod 209 to be compressed. At the same time, the rectangular plate 207 drives the second protrusion 208 to disengage from the inside of the limiting groove 205, and the second spring 202 is reset to push the first protrusion 203 downward along the rectangular holes opened on both sides of the connecting block 201. At the same time, the first protrusion 203 drives the externally installed extrusion block 204 to move downward, so that the bottom surface of the extrusion block 204 contacts the top surface of the sample tank 4 and reinforces the sample tank 4.

[0035] like Figure 3 and Figure 4 As shown, the rectangular plate 207 slides horizontally inside the rectangular hole 206, and the bottom of the first spring telescopic rod 209 is fixedly connected to the inner wall of the rectangular hole 206;

[0036] The second protrusion 208 matches the size of the extrusion block 204, and the bottom surface of the extrusion block 204 contacts the top surface of the sample cover 5; rectangular holes are opened on both sides of the outside of the connecting block 201, and the outside of the first protrusion 203 contacts the inner wall of the rectangular hole.

[0037] The above scheme is adopted: by pushing the rectangular plate 207 to slide horizontally along the inside of the rectangular hole 206, and the rectangular plate 207 squeezes the first spring telescopic rod 209 to be compressed, and at the same time the rectangular plate 207 drives the second protrusion 208 to move, so that the second protrusion 208 is disengaged from the inside of the limiting groove 205, and the second spring 202 is reset to push the first protrusion 203 and the squeezing block 204 to move downward, so that the bottom surface of the squeezing block 204 contacts the top of the sample tank 4, and the squeezing block 204 presses the top surface of the sample tank 4 to increase the stability of the sample tank 4, and at the same time reduce the bumps in the transportation of food samples, which may cause leakage of samples.

[0038] like Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a groove is provided inside the bottom of the first connection block 303, the bottom of the third spring 314 contacts the top surface of the second connection block 311, and the top of the third spring 314 contacts the top surface of the groove;

[0039] The bottom of the push block 309 is convex, and the bottom of the push block 309 slides horizontally inside the rectangular hole 305;

[0040] A plurality of holes are formed on the outside of the sampler 313 , and the outsides of two adjacent samplers 313 are in contact with each other.

[0041] The above scheme is adopted: by pushing the pushing block 309, the first connecting block 303 is driven to squeeze the second spring telescopic rod 304 to be compressed, so that the first connecting block 303 is deflected along the inside of the rectangular hole 305 and the outside of the connecting round rod 310, and at the same time, the first connecting block 303 drives the second connecting block 311, the third connecting block 312 and the sampler 313 to deflect. By reducing the angle of the upper end of the first connecting block 303, the angle of the sampler 313 is driven to increase, which is convenient for the sampler 313 to clamp the solid sample. At the same time, a plurality of holes are arranged on the outside of the sampler 313 to discharge the liquid carried in the process of clamping the solid sample, thereby improving the efficiency of solid sample detection and the accuracy of solid sample detection data.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the storage assembly 1 also includes a classification rack 103 installed at the bottom of the connecting block 201, a first spring 105 fixedly mounted on the outside of the first protrusion 203, a fixing plate 104 installed on the top of the first spring 105, a storage box 101 arranged outside the classification rack 103, and a box door 102 installed on the outer front surface of the storage box 101; the classification rack 103 is in a "cross" shape, and the number of the first springs 105 is multiple and evenly distributed at the bottom of the fixing plate 104;

[0043] A handle is installed on the external front of the box door 102, a "C"-shaped block is arranged on the top of the storage box 101, and a pulley is installed on the bottom of the storage box 101.

[0044] The above scheme is adopted: the classification rack 103 is in a "cross" shape, which improves the flexibility of the device and facilitates the classification of different samples. There are multiple first springs 105 and they are evenly distributed at the bottom of the fixed plate 104. When the sample is in the transportation process, the multiple first springs 105 reduce the shaking of the sample inside the sample cover 5 to prevent the sample from leaking. A handle is installed on the outside of the box door 102 to facilitate the staff to quickly open the device and improve the speed of taking samples. There is a "C"-shaped block on the top of the storage box 101, and a pulley is installed on the bottom of the storage box 101, which improves the flexibility of the device and facilitates the movement of the device through the pulley.

[0045] The working principle and use process of the present invention:

[0046] First, the staff opens the box door 102 to take out the sample cover 5 on the top of the classification rack 103. After the sample cover 5 is taken out, the sample tank 4 is rotated to separate the sample tank 4 from the inside of the sample cover 5. The clamping block 302 is driven to squeeze the outside of the airbag 301 by pushing the pushing block 309. At the same time, after the airbag 301 is forced to exhaust the internal air, the external air will be sucked in from the bottom of the sampling tube 315 due to the loss of the squeezing force. The liquid sample is sucked into the inside through the sampling tube 315, and the inhaled sample is filtered by the filter block 316 installed inside the bottom of the sampling tube 315 to prevent the inhaled solid sample from entering the sampling tube 315. 5, when the pushing block 309 drives the clamping block 302 to squeeze the airbag 301, the pushing block 309 drives the first connecting block 303 to rotate along the outside of the connecting round rod 310 and the inside of the rectangular hole 305, and the first connecting block 303 squeezes the second spring telescopic rod 304 to be compressed, so that the position of the first connecting block 303 is deflected. At this time, the angle of the upper end of the first connecting block 303 becomes smaller, and at the same time, the first connecting block 303 drives the angle of the second connecting block 311 connected to the bottom to become larger, and drives the third connecting block 312 and the sampler 313 to expand to both sides through the second connecting block 311. When the staff releases the pushing block 309, at this time, the second spring telescopic rod 304 is reset, and at the same time, the first connecting block 303, the second connecting block 311, the third connecting block 312 and the third spring 314 are reset, and the solid sample is clamped into the interior of the sampler 313 by the third spring 314, and a plurality of holes are provided on the outside of the sampler 313, so that the clamped liquid flows out through the holes, and the staff puts the taken liquid sample and solid sample into the sample cover 5, rotates the sample tank 4 into the interior of the sample cover 5, and puts the sample cover 5 back on the top surface of the classification rack 103, at this time, the second protrusion 208 and the limiting groove 205 are in a locked state, and the second The spring 202 is in a compressed state, and the staff pushes the rectangular plate 207 to move horizontally along the inside of the rectangular hole 206 and squeeze the first spring telescopic rod 209 to be compressed. At the same time, the rectangular plate 207 drives the second protrusion 208 to disengage from the inside of the limiting groove 205, and the second spring 202 is reset to push the first protrusion 203 downward along the rectangular holes opened on both sides of the connecting block 201. At the same time, the first protrusion 203 drives the externally installed extrusion block 204 to move downward, so that the bottom surface of the extrusion block 204 contacts the top surface of the sample tank 4, and the sample tank 4 is reinforced by pressing the extrusion block 204. The box door 102 can be closed.
