Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection equipment technology, and in particular to a rapid detection device for selenium content in selenium-rich agricultural products. Background Technology
[0002] Selenium is a non-metallic chemical element belonging to the oxalic group. Selenium plays an important role in nature, organisms, and industry. Adequate intake of selenium is essential for maintaining human health. However, selenium-enriched agricultural products require testing equipment to detect their selenium content during production and processing.
[0003] Existing equipment for detecting selenium content in selenium-enriched agricultural products typically involves cutting the product into pieces, placing the pieces and a specific reagent into a test tube, inserting the test tube into the detection chamber of the device, allowing the selenium to react with the reagent to generate a fluorescent signal, which the device then detects to quantify and determine the selenium content.
[0004] However, when personnel change agricultural product samples, their large hand movements can easily cause them to bump into the machine, resulting in the machine shifting on the table after being hit, falling off the table and getting damaged, thus affecting the stability and safety of the machine. Utility Model Content
[0005] The technical problem this invention aims to solve is that when personnel change agricultural product samples, their large hand movements can easily cause them to collide with the machine body, resulting in the machine body shifting on the table after the collision, falling off the table and being damaged, thus affecting the stability and safety of the machine body.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a rapid detection device for selenium content in selenium-enriched agricultural products, including a body, which is placed on a table to detect the selenium content in the agricultural products; a detection chamber, which is set on the body, and is used to carry the agricultural products and detect the selenium content; and a positioning component, which is installed at the bottom of the body and limits the body by squeezing the edge of the table.
[0007] Preferably, the positioning component includes: a telescopic rod, which is fixedly installed on the machine body and has a reinforcing component, wherein the moving end of the telescopic rod has a hole; a screw ring, wherein the screw ring is rotatably installed on the telescopic rod by engaging with a retaining ring and a retaining groove; and a pressure plate, wherein a screw is fixedly connected to one side of the pressure plate, wherein the surface of the screw is threadedly connected to the inner wall of the screw ring, and wherein the screw slides up and down in the hole of the telescopic rod.
[0008] The effect achieved by the above components is as follows: By setting the positioning component, the telescopic rod is first manually stretched to its maximum position, and the machine body is placed near the edge of the table, so that the pressure plate is located below the edge of the table. At this time, the screw hole ring is manually rotated, so that the screw hole ring rotates at a fixed point under the engagement of the retaining ring and the retaining groove. During the rotation, the screw hole ring drives the screw to move up and down. During this process, the pressure plate can be limited by hand, so that the screw drives the pressure plate to move towards the table. The pressure plate moves to the position of pressing the table to hold and fix the telescopic rod and the machine body, thereby achieving the reinforcement of the machine body and reducing the possibility of the machine body shifting on the table after being hit, causing the machine body to fall off the table and be damaged. This improves the stability and safety of the machine body.
[0009] Preferably, the positioning component further includes a rubber strip, wherein the rubber strip is uniformly fixed to the screw ring to increase the friction with the hand.
[0010] The effect achieved by the above-mentioned components is that by setting the rubber strip, the friction between the hand and the surface of the screw hole ring can be increased, reducing the chance of the hand slipping.
[0011] Preferably, the positioning component further includes a rubber pad, which is fixed to the pressure plate, wherein the rubber pad has multiple protrusions to increase the friction and fit between the pressure plate and the table surface.
[0012] The effect achieved by the above components is that by setting rubber pads, the fit and friction between the pressure plate and the table surface can be increased, reducing the possibility of the pressure plate sliding or shaking.
[0013] Preferably, the positioning component further includes a support plate, wherein the support plate is fixed between the pressure plate and the screw to support the pressure plate, and wherein the surface of the support plate is trapezoidal.
[0014] The effect achieved by the above components is that by setting up a support plate, the pressure plate can be further supported and reinforced, reducing the possibility of the pressure plate tilting significantly on the side away from the screw during use.
[0015] Preferably, the positioning component further includes a positioning post, which is fixedly connected to the moving end of the telescopic rod, wherein the positioning post is placed in the slide of the telescopic rod to limit the movement of the moving end of the telescopic rod.
[0016] The effect achieved by the above components is that by setting the positioning post, the positioning post can slide along the slide of the telescopic rod, and when it moves to the maximum position, it limits the moving end of the telescopic rod, reducing the possibility of the telescopic rod separating.
[0017] Preferably, the reinforcing component includes: a perforated plate fixedly connected to the side of the telescopic rod near the slide rail; an L-shaped plate fixedly connected to the positioning post, wherein the L-shaped plate slides along the surface of the perforated plate; and a spring rod slidably mounted on the L-shaped plate, wherein the other end of the spring rod is fixedly connected to the L-shaped plate, and wherein the spring rod is inserted into the perforated plate to fix the L-shaped plate and the positioning post.
[0018] The effect achieved by the above components is as follows: by setting up the reinforcement components, when the positioning column moves, it drives the L-shaped plate and the spring rod to move. After the pressure plate completes the positioning of the machine body, the position of the spring rod corresponds to the position of any hole on the perforated plate. At this time, under the reaction force of the spring, the spring rod inserts into the interior position of the L-shaped plate and the perforated plate, fixing the L-shaped plate and the positioning column, thereby achieving the positioning and reinforcement of the telescopic rod, so that the telescopic rod can be locked and cannot move, reducing the situation where the telescopic rod moves during use due to force, affecting the positioning stability of the machine body.
[0019] Preferably, the reinforcement component further includes a pull plate, wherein the pull plate is fixed to the spring rod to provide a point of leverage for personnel.
[0020] The effect achieved by the above components is that by setting up a pull plate, the contact area of the manually moved spring rod can be increased, thereby improving the convenience of manually pulling the spring rod.
[0021] The beneficial effects of this utility model are:
[0022] By setting up positioning components, the unit placed on the table can be limited and reinforced, reducing the possibility of the unit shifting on the table after being hit, causing it to fall off the table and be damaged, thus improving the stability and safety of the unit.

[0031] Figure 1-4 The device shown is a rapid detection device for selenium content in selenium-enriched agricultural products, comprising a body 1, which is placed on a table to detect the selenium content in the agricultural products; a detection chamber 2, which is set on the body 1 and is used to hold the agricultural products and detect the selenium content; and a positioning component 3, which is installed at the bottom of the body 1 and limits the body 1 by squeezing the edge of the table.
[0032] Figure 2 and Figure 3The positioning component 3 shown includes: a telescopic rod 31, which is fixedly installed on the machine body 1, and a reinforcing component 4 is provided on the telescopic rod 31, wherein the moving end of the telescopic rod 31 has a hole; a screw ring 35, wherein the screw ring 35 is rotatably installed on the telescopic rod 31 by engaging with a retaining ring and a retaining groove; and a pressure plate 34, wherein a screw 33 is fixedly connected to one side of the pressure plate 34, wherein the surface of the screw 33 is threadedly connected to the inner wall of the screw ring 35, and the screw 33 slides up and down in the hole of the telescopic rod 31. By setting the positioning component 3, the telescopic rod 31 is first manually stretched to the maximum position, and the machine body 1 is placed near the edge of the table, so that the pressure plate 31 is properly positioned. The plate 34 is located below the edge of the table. At this time, the screw hole ring 35 is manually rotated, so that the screw hole ring 35 rotates at a fixed point under the engagement of the retaining ring and the retaining groove. During the rotation, the screw hole ring 35 drives the screw 33 to move up and down. During this process, the pressure plate 34 can be limited by hand, so that the screw 33 drives the pressure plate 34 to move closer to the table. The pressure plate 34 moves to the position of pressing the table to hold and fix the telescopic rod 31 and the machine body 1, thereby achieving the placement and reinforcement of the machine body 1. This reduces the possibility of the machine body 1 shifting on the table after being hit, causing the machine body 1 to fall off the table and be damaged, and improves the stability and safety of the machine body 1.
[0033] Figure 2 and Figure 3 The positioning component 3 shown also includes: a rubber strip 36, wherein the rubber strip 36 is uniformly fixed to the screw hole ring 35 to increase the friction with the hand. By setting the rubber strip 36, the friction between the hand and the surface of the screw hole ring 35 can be increased, reducing the possibility of hand slippage. The positioning component 3 also includes: a rubber pad 37, which is fixed to the pressure plate 34. The rubber pad 37 has multiple protrusions to increase the friction and fit between the pressure plate 34 and the table surface. By setting the rubber pad 37, the fit and friction between the pressure plate 34 and the table surface can be increased, reducing the possibility of the pressure plate 34 sliding or shaking.
[0034] Figure 2 and Figure 3 The positioning component 3 shown also includes a support plate 38, which is fixed between the pressure plate 34 and the screw 33 to support the pressure plate 34. The surface of the support plate 38 is trapezoidal. By setting the support plate 38, the pressure plate 34 can be auxiliaryly supported and reinforced, reducing the possibility of the pressure plate 34 tilting significantly away from the screw 33 during use. The positioning component 3 also includes a positioning post 32, which is fixed to the moving end of the telescopic rod 31. The positioning post 32 is placed in the slide of the telescopic rod 31 to limit the moving end of the telescopic rod 31. By setting the positioning post 32, the positioning post 32 can slide along the slide of the telescopic rod 31 and limit the moving end of the telescopic rod 31 when it moves to the maximum position, reducing the possibility of the telescopic rod 31 separating.
[0035] Figure 3 and Figure 4 The reinforcing component 4 shown includes: a perforated plate 44, which is fixedly connected to the side of the telescopic rod 31 near the slide rail; an L-shaped plate 41, which is fixedly connected to the positioning post 32, wherein the L-shaped plate 41 slides along the surface of the perforated plate 44; and a spring rod 42, which is slidably mounted on the L-shaped plate 41, wherein the other end of the spring rod 42 is fixedly connected to the L-shaped plate 41, and wherein the spring rod 42 is inserted into the perforated plate 44 to fix the L-shaped plate 41 and the positioning post 32. By setting the reinforcing component 4, when the positioning post 32 moves, it will bring... The L-shaped plate 41 and spring rod 42 move, and after the pressure plate 34 completes the positioning of the machine body 1, the position of the spring rod 42 corresponds to the position of any hole on the perforated plate 44. At this time, under the reaction force of the spring, the spring rod 42 is inserted into the interior of the L-shaped plate 41 and the perforated plate 44, fixing the L-shaped plate 41 and the positioning post 32, thereby achieving the positioning and reinforcement of the telescopic rod 31, so that the telescopic rod 31 can be locked and cannot move, reducing the possibility of the telescopic rod 31 moving under force during use and affecting the positioning stability of the machine body 1.
[0036] Figure 3 and Figure 4 The reinforcement component 4 shown also includes a pull plate 43, which is fixed to the spring rod 42 to provide a point of leverage for personnel. By setting the pull plate 43, the contact area of the spring rod 42 can be increased, thereby improving the convenience of manually pulling the spring rod 42.
[0037] Working principle: First, the selenium-enriched agricultural products are cut into pieces. Then, the cut agricultural products and specific reagents are placed into a test tube and the test tube is inserted into the detection chamber 2 of the machine body 1. Selenium reacts with the specific reagents to generate a fluorescent signal. Then, the detection mechanism inside the machine body 1 detects the fluorescence intensity and determines the selenium content by fluorescence intensity quantification.
[0038] First, manually extend the telescopic rod 31 to its maximum position and place the machine body 1 near the edge of the table, so that the pressure plate 34 is located below the edge of the table. At this time, manually rotate the screw ring 35 so that the screw ring 35 rotates at a fixed point under the engagement of the retaining ring and the retaining groove. During the rotation, the screw ring 35 drives the screw 33 to move up and down. During this process, you can use your hand to limit the pressure plate 34, so that the screw 33 drives the pressure plate 34 to move towards the table. This moves the pressure plate 34 to the position of pressing the table to hold and fix the telescopic rod 31 and the machine body 1, thereby achieving the placement and reinforcement of the machine body 1.
[0039] When the positioning post 32 moves, it drives the L-shaped plate 41 and the spring rod 42 to move. After the pressure plate 34 completes the positioning of the machine body 1, the position of the spring rod 42 corresponds to the position of any hole on the perforated plate 44. At this time, under the reaction force of the spring, the spring rod 42 is inserted into the interior of the L-shaped plate 41 and the perforated plate 44, fixing the L-shaped plate 41 and the positioning post 32, thereby achieving the positioning and reinforcement of the telescopic rod 31, so that the telescopic rod 31 can be locked and cannot move.
