DETAILED DESCRIPTION

[0017] The embodiment of the present application discloses a placer for food safety detection, in which a plurality of clamping assemblies 3 are arranged at intervals on a base 1, and the clamping assembly 3 includes a plurality of limit rods 31 arranged at equal intervals along the circumference of a test tube 2, and the plurality of limit rods 31 can move toward or away from the axial centerline direction of the test tube 2 to clamp the test tube 2, and a fixed seat 33 that can vertically reciprocate along the limit rod 31 is provided on each of the plurality of limit rods 31, and the test tube 2 is located between the plurality of fixed seats 33, and by adjusting the position of the limit rod 31, the test tubes 2 of different sizes can be limited, without using a plurality of matching test tube racks, thereby improving space utilization to a certain extent.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1-Figure 3 A food safety detection placing device comprises a base 1, on which a plurality of clamping assemblies 3 for limiting a test tube 2 are arranged at intervals, the clamping assembly 3 comprises a plurality of limiting rods 31 and a limiting member 32, the plurality of limiting rods 31 are arranged at equal intervals along the circumference of the test tube 2, the limiting member 32 comprises a first slider 321, a plurality of first slide grooves 11 are respectively provided at positions corresponding to the plurality of limiting rods 31 on the upper surface of the base 1, the extension lines of the long sides of the plurality of first slide grooves 11 all pass through the axis line of the test tube 2, the plurality of first sliders 321 are respectively slidably connected to the plurality of first slide grooves 11, the plurality of first sliders 321 are respectively slidably connected to the plurality of limiting rods 31, and the plurality of first sliders 321 are respectively slidably connected to the plurality of limiting rods 31. 1 is fixedly connected at the bottom end, and a spring 322 is arranged in each of the plurality of first slide grooves 11. The spring 322 is arranged on the side of the first slider 321 away from the test tube 2. When the spring 322 is in the initial position, the first slider 321 fits with the end of the first slide groove 11 close to the test tube 2, and the test tube 2 is placed between the plurality of limiting rods 31. The plurality of limiting rods 31 move in a direction away from the test tube 2. The spring 322 is compressed and simultaneously applies a thrust to the limiting rod 31 to limit the position of the test tube 2. By adjusting the position of the limiting rod 31, the test tubes 2 of different sizes can be limited, thereby improving the space utilization rate to a certain extent.

[0020] Reference Figure 2-Figure 4The second slide groove 311 is provided on the side of the plurality of limit rods 31 close to the test tube 2, and a second slider 34 is slidably connected in the plurality of second slide grooves 311, and a fixing seat 33 is fixedly connected to the plurality of second sliders 34. The fixing seat 33 is L-shaped, and the fixing seat 33 can reciprocate vertically along the limit rod 31, so that the test tube 2 is placed between the plurality of fixing seats 33 so that the test tube 2 does not contact the limit rod 31. The limit rod 31 is relatively long. If the limit rod 31 directly contacts the test tube 2, the test tube 2 may be worn when it is pushed toward the base 1. A sponge pad 35 is fixedly connected to the top of the vertical side of the fixing seat 33 close to the test tube 2 to protect the test tube 2. The fixing seat 33 is close to the test tube 2. A flexible anti-skid pad 36 is fixedly connected to the vertical side surface near the test tube 2 and located below the sponge pad 35. The thickness of the flexible anti-skid pad 36 is less than that of the sponge pad 35. A flexible gasket is fixedly installed at the upper corner position of the end of the fixing seat 33 close to the axis line of the test tube 2 to prevent the test tube 2 from being scratched. When the test tube 2 is inserted between multiple fixing seats 33, the test tube 2 first abuts against the sponge pad 35, and then the test tube 2 is moved downward until the test tube 2 is in contact with the flexible gasket and the fixing seat 33 is in contact with the base 1. As time goes by, the sponge pad 35 is deformed, and the test tube 2 slowly fits against the flexible anti-skid pad 36. The flexible anti-skid pad 36 increases the friction between it and the test tube 2, making it difficult for the test tube 2 to move.

[0021] Reference Figure 4 The second slide groove 311 is provided with a plurality of arc grooves at the top and bottom of the vertical side surfaces, and the second slide block 34 is fixedly connected with an arc protrusion 37 at the corresponding position of the arc groove, and the arc protrusion 37 is movably engaged with the arc groove at the corresponding position. When the fixing seat 33 is in contact with the base 1, the arc protrusion 37 is engaged with the arc groove at the corresponding position, limiting the position of the second slide block 34, making the position of the test tube 2 more stable. When the test tube 2 is moved upward, the second slide block 34 moves toward the top of the second slide groove 311 until the second slide block 34 is in contact with the top surface of the second slide groove 311. At this time, the arc protrusion 37 is movably engaged with the arc groove at the top, and the test tube 2 continues to move upward until the test tube 2 is separated from the fixing seat 33. At this time, the fixing seat 33 is located at the top of the limit rod 31, which is convenient for next use.

[0022] The working principle of the embodiment of the present application is: during the food testing process, when a small number of test tubes 2 of multiple sizes are needed, the bottom end of the test tube 2 is aligned with the position between the multiple fixing seats 33, and the test tube 2 is pressed downward. When the test tube 2 is inserted between the multiple fixing seats 33, the spring 322 is compressed. The spring 322 is compressed and simultaneously applies a thrust to the limit rod 31. The test tube 2 first abuts against the sponge pad 35, and then the test tube 2 is moved downward until the test tube 2 is in contact with the flexible gasket and the fixing seat 33 is in contact with the base 1. As time goes by, the sponge pad 35 is deformed, and the test tube 2 slowly fits with the flexible anti-skid pad 36. At this time, the position of the limit rod 31 changes accordingly, and the flexible anti-skid pad 36 increases the friction between it and the test tube 2, making it difficult for the test tube 2 to move. By adjusting the position of the limit rod 31, it is possible to limit the test tubes 2 of different sizes, thereby improving the space utilization rate to a certain extent.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
