Description

Technical Field

[0001] The utility model relates to the technical field of food hygiene and safety detection, in particular to a food hygiene and safety detection instrument. Background Art

[0002] Food quality and food hygiene are closely related to people's life and health. Therefore, before food enters the market, it is usually necessary to use a food safety tester for testing. Food safety testing plays an important role in ensuring food safety. Therefore, it is very necessary to detect food contaminant residues. For example, in the patent with the announcement number "CN215575017U" and the name of the patent "A Food Safety Assessment and Testing Device", a constant tube is set, the medicine box is opened, and the medicine required for testing is poured into the corresponding storage tank. The second hydraulic cylinder is started to drive the extrusion plug to pull backward, so that the medicine is drawn into the constant tube through the first one-way valve. After that, the second hydraulic cylinder is started again to press the medicine in the constant tube into the connecting tube through the second one-way valve, and the medicine is pressed into the extraction bottle through the connection between the connecting tube and the injection head, thereby realizing a stable and accurate addition process of the medicine. However, the above structure still has the following problems during actual use:

[0003] During use, the above structure adds the reagents required for testing by pouring them into the corresponding storage tanks. However, when samples need to be tested later, they need to be taken out one by one. Since the storage tanks are embedded in the entire device, it is inconvenient to take them out, which affects the staff's access and thus affects the efficiency of testing.

[0004] Therefore, we proposed that food hygiene and safety testing instruments can solve the above problems very well. Utility Model Content

[0005] The purpose of the present utility model is to provide a food hygiene and safety testing instrument to solve the problem raised in the above-mentioned background technology that when samples need to be tested in the current market, they need to be taken one by one, and because the storage tank is embedded in the entire device, it is inconvenient to take it out, which affects the staff's retrieval and thus affects the efficiency of testing.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a food hygiene and safety detector, comprising a detector body and a sample storage tube placed inside the detector body for storing samples;

[0007] The device further comprises: a servo motor is fixedly installed inside the detector body, an output end of the servo motor is fixed to a rotating shaft, and the other end of the rotating shaft is connected to a bearing of the detector body, and a first gear is fixed to the outer side of the rotating shaft;

[0008] A lifting mechanism is provided on one side of the first gear, which drives the sample storage tube to rise and fall through the support seat so as to facilitate access.

[0009] Preferably, the lifting mechanism includes a first gear rod and a connecting rod, wherein one side of the first gear rod is engaged with the first gear, and the lower end of the first gear rod is fixed to the connecting rod.

[0010] Preferably, a sliding connection is formed between the connecting rod and the detector body, and the upper end of the connecting rod is fixed to the support seat, and a sample storage tube is placed above the support seat.

[0011] Preferably, both sides of the sample storage tube are fitted with a limiting ring, and the limiting ring is arranged in an arc-shaped structure. At the same time, the limiting ring forms an elastic sliding connection with the detector body through a pressure spring, and the two ends of the pressure spring are respectively fixed to the limiting ring and the detector body.

[0012] Preferably, a pull rope is wound around one end of the rotating shaft, and the other end of the pull rope is fixed to the rotating rod, and both ends of the rotating rod are connected to the main bearing of the detector.

[0013] Preferably, a torsion spring is sleeved on one end of the rotating rod, and a second gear is fixed in the middle of the rotating rod, and the second gear is meshed with the second gear rod.

[0014] Preferably, the second gear rod is in sliding connection with the detector body, and the upper end of the second gear rod extends out of the detector body and is fixed to the lower end surface of the sample placement table.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the food hygiene and safety detector is not only convenient for inspectors to use, thereby making it easy to take out the sample storage tube and improving the efficiency of detection, but also can simply limit the sample storage tube to prevent the sample storage tube from shaking and hitting during transportation and causing it to break, and the sample placement table is raised out of the detector body, making it easier for inspectors to remove the tested sample and place a new sample. The specific contents are as follows:

[0016] (1) The first gear rotates, thereby causing the first gear to drive the meshed first gear rod to move upward, thereby driving the connecting rod upward, thereby causing the connecting rod to drive the support seat upward, thereby causing the support seat to drive the sample storage tube placed above it upward, thereby causing the upper end of the sample storage tube to slide out of the detector body, thereby facilitating the detection personnel to use it, thereby making it convenient to use the sample storage tube and improving the detection efficiency;

[0017] Furthermore, the connecting rods are connected and fixed to each other, so that multiple groups of support seats drive the sample storage tubes upward at the same time, thereby eliminating the need to control a group separately for lifting and lowering, which is more practical.

[0018] By setting the limiting ring, the sample storage tube can be simply limited to avoid the sample storage tube from shaking and hitting during transportation, which may cause it to break. At the same time, the elastic force of the pressure spring can ensure that the limiting ring and the sample storage tube are effectively fitted, so that it can perform a stable limiting function.

[0019] (2) As the shaft rotates, the pull rope is reeled in, causing the pull rope to generate tension to pull the rotating rod to rotate, which in turn causes the rotating rod to drive the second gear to rotate together, thereby causing the second gear to drive the meshed second gear rod to rise synchronously, and then the second gear rod drives the sample placement table to rise together, thereby causing the sample placement table to rise out of the detector body, making it easier for the tester to take down the tested sample and place a new sample;

[0020] Furthermore, the elastic force of the torsion spring drives the rotating rod to reverse, thereby causing the rotating rod to drive the second gear to reverse, and then the second gear drives the sample placement table to descend together through the second gear rod, and then the sample placement table is lowered again into the detector body, thereby facilitating the purpose of detection.

[0028] 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 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 are within the scope of protection of the present invention.

[0029] See also Figures 1-6 , the utility model provides the following technical solutions:

[0030] Example 1: In order to solve the problem in the prior art that when samples need to be tested, they need to be taken one by one, and because the storage tank is embedded in the entire device, it is inconvenient to take it out, which in turn affects the staff's access to it, thereby affecting the efficiency of the test, the following solution is disclosed, including a detector body 1 and a sample storage tube 2 for storing samples placed inside the detector body 1; further comprising: a servo motor 5 is fixedly installed inside the detector body 1, and the output end of the servo motor 5 is fixed to the rotating shaft 6, and the other end of the rotating shaft 6 is fixed to the rotating shaft 6. The end is connected to the bearing of the detector body 1, and a first gear 7 is fixed to the outside of the rotating shaft 6; a lifting mechanism is provided on one side of the first gear 7, which drives the sample storage tube 2 to rise and fall through the support seat 10 to facilitate access, and the lifting mechanism includes a first gear rod 8 and a connecting rod 9, wherein one side of the first gear rod 8 is engaged with the first gear 7, and the lower end of the first gear rod 8 is fixed to the connecting rod 9, a sliding connection is formed between the connecting rod 9 and the detector body 1, and the upper end of the connecting rod 9 is fixed to the support seat 10, and the sample storage tube 2 is placed above the support seat 10.

[0031] By starting the servo motor 5, the servo motor 5 drives the rotating shaft 6 to rotate, and through the rotation of the rotating shaft 6, the rotating shaft 6 drives the fixed first gear 7 to rotate together, and through the rotation of the first gear 7, the first gear 7 drives the meshed first gear rod 8 to move upward, and through the fixation between the first gear rod 8 and the connecting rod 9, the connecting rod 9 is driven upward together, and the connecting rod 9 drives the support seat 10 upward together, so that the support seat 10 drives the sample storage tube 2 placed above it upward, and the upper end of the sample storage tube 2 slides out of the detector body 1, making it easy for the detection personnel to take it, thereby making it convenient to take the sample storage tube 2 and improving the detection efficiency. At the same time, the connecting rods 9 are connected and fixed to each other, so that multiple groups of support seats 10 drive the sample storage tubes 2 upward at the same time, so that there is no need to control one group separately for lifting and lowering, which is more practical.

[0032] Example 2: The existing sample storage tube 2 is prone to collision and rupture during transportation. Therefore, the following solution is disclosed to avoid the sample storage tube 2 from shaking and rupture during transportation. For details, refer to Figure 2-Figure 3 The two sides of the sample storage tube 2 are fitted with the limiting ring 3, and the limiting ring 3 is arranged in an arc-shaped structure. At the same time, the limiting ring 3 forms an elastic sliding connection with the detector body 1 through the pressure spring 4, and the two ends of the pressure spring 4 are respectively fixed to the limiting ring 3 and the detector body 1.

[0033] At the same time, limiting rings 3 are set on both sides of the sample storage tube 2. Through the setting of the limiting rings 3, the sample storage tube 2 can be simply limited to prevent the sample storage tube 2 from shaking and hitting during transportation and causing breakage. At the same time, the elastic force of the pressure spring 4 can ensure that the limiting ring 3 and the sample storage tube 2 are effectively fitted, so that it can perform a stable limiting function.

[0034] Example 3: Add a new technical solution based on Example 1, so as to facilitate the test personnel to take down the tested samples and put new samples. Figure 1 and Figure 6 A pull rope 11 is wrapped around one end of the rotating shaft 6, and the other end of the pull rope 11 is fixed to the rotating rod 12, and both ends of the rotating rod 12 are connected to the bearing of the detector body 1, and a torsion spring 14 is sleeved on one end of the rotating rod 12. At the same time, a second gear 13 is fixed in the middle of the rotating rod 12, and the second gear 13 is engaged with the second gear rod 15. The second gear rod 15 and the detector body 1 form a sliding connection, and the upper end of the second gear rod 15 extends out of the detector body 1 and is fixed to the lower end surface of the sample placement table 16.

[0035] At the same time, when the rotating shaft 6 rotates, it will also reel in the pull rope 11, thereby causing the pull rope 11 to generate tension to pull the rotating rod 12 to rotate. Through the rotation of the rotating rod 12, the rotating rod 12 drives the second gear 13 to rotate together, so that the second gear 13 drives the meshed second gear rod 15 to rise synchronously, and then the second gear rod 15 drives the sample placement table 16 to rise together, so that the sample placement table 16 is lifted out of the detector body 1, making it convenient for the inspector to take down the inspected sample and place a new sample. Then, the servo motor 5 drives the rotating shaft 6 to reverse, so that the rotating shaft 6 no longer reels the pull rope 11. At this time, the pull rope 11 no longer generates tension on the rotating rod 12. At this time, the elastic force of the torsion spring 14 can drive the rotating rod 12 to reverse, so that the rotating rod 12 drives the second gear 13 to reverse, and then the second gear 13 drives the sample placement table 16 to descend together through the second gear rod 15, and then the sample placement table 16 is lowered into the detector body 1 again, thereby facilitating the purpose of detection.
