Description

Technical Field

[0001] This utility model relates to the field of water sample storage technology, and in particular to a water sample storage box that is easy to handle. Background Technology

[0002] Water is one of the most important resources for human survival. People cannot live or produce without water. Water sample testing uses modern science and technology to analyze the composition of water samples, thereby determining the quality of the aquatic environment and the degree of water pollution. Because water quality is directly related to human health, water quality testing is crucial. An existing water sample storage box (publication number CN 217171509 U) is designed for easy handling. It features an adjustable clamping device with clamps on the clamps to limit the position of water sample bottles. Adjusting the distance between the clamps allows for adjustment of the clamp diameter, achieving a secure hold for water sample bottles of different diameters. However, when using this device to secure the sample bottle, rotating the screw adjusts the position of the entire clamp, sometimes loosening or fully clamping the water sample, causing inconvenience in handling the sample.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By incorporating a pick-and-place mechanism within the support structure, the universal wheel changes its contact area with the guide rail as the drum and guide rail rotate. When the protruding part of the guide rail contacts the universal wheel, the fixed plate pushes the sliding plate upward, which in turn pulls the connecting rod upward under the limit of the guide column. The connecting rod pulls the clamping plate outward, releasing the test tube. Simultaneously, the ejector assembly lifts the test tube. When the universal wheel contacts the lower part of the guide rail, the spring pushes the fixed plate and sliding plate downward, causing the connecting rod to push the clamping plate closer to the test tube, clamping and limiting the test tube placed on the inner side. This makes the overall operation simple and quick, improving the convenience of use. Attached Figure Description

[0027] In this embodiment: the pick-and-place mechanism includes a pick-and-place assembly circumferentially arranged around the support shaft 12. The pick-and-place assembly includes a support cylinder 21 fixed on the support plate 13. A clamping plate 22 is arranged opposite to the inner side of the support cylinder 21, and a connecting rod 23 is arranged on the outer side of the clamping plate 22. A sliding groove 231 is provided on the connecting rod 23. A through groove is provided on the support cylinder 21 through which the connecting rod 23 passes, and a guide post 201 passing through the sliding groove 231 is provided in the through groove. The other end of the connecting rod 23 is connected to a sliding plate 24. A fixing plate 25 is provided at the lower end of the sliding plate 24. The fixing plate 25 is located below the support plate 13. A spring 26 is provided between the fixing plate 25 and the support plate 13. The springs 26 are spaced apart on the fixing plate 25. The two ends of the springs 26 are fixedly connected to the fixing plate 25 and the support plate 13, respectively. The connecting rod 23 is rotatably connected to the clamping plate 22 and the sliding plate 24 through a pin. The movable plate 24 is slidably connected to the support plate 13. The connecting rod 23 is provided in two places on the clamping plate 22. The connecting rod 23 is slidably connected to the guide post 201. The lower end of the fixed plate 25 is equipped with a universal wheel 28. The upper end of the fixed plate 25 is provided with an ejector assembly that passes through the support plate 13. As the contact part of the universal wheel 28 with the guide rail 29 changes, when the protruding part of the guide rail 29 contacts the universal wheel 28, the fixed plate 25 presses the spring 26 upward, pushing the sliding plate 24 to move upward. The sliding plate 24 pulls the connecting rod 23 to move upward under the limit of the guide post 201. The connecting rod 23 pulls the clamping plate 22 to separate outward, releasing the test tube. When the universal wheel 28 contacts the lower part of the guide rail 29, the spring 26 pushes the fixed plate 25 and the sliding plate 24 downward, causing the connecting rod 23 to push the clamping plate 22 closer to the test tube placed on the inner side to clamp and limit it.

As the guide rail 29 rotates with the rotating drum 14, when the protruding part of the guide rail 29 contacts the caster wheel 28, it pushes it upward, causing the push rod 27 on the fixed plate 25 to move upward and push the test tube placed on it upward to open the material removal hole 16 for easy material removal.

[0029] The working principle and usage process of this utility model are as follows: When picking up and placing test tubes, rotating the handle 15 causes the rotating drum 14 to rotate under the support of the base 11. As the guide rail 29 rotates with the rotating drum 14, the protruding part of the guide rail 29 pushes the universal wheel 28 upward. The fixing plate 25 presses the spring 26 upward, pushing the sliding plate 24 to move upward. The sliding plate 24 pulls the connecting rod 23 to move upward under the limit of the guide post 201. The connecting rod 23 pulls the clamping plate 22 to separate outward. At the same time, the push rod 27 pushes the test tube upward to move it out of the material picking hole 16, completing the picking and placing operation of the test tube. When the rotating drum 14 drives the guide rail 29 to rotate to the point where the universal wheel 28 is at the lowest position, the spring 26 pushes the fixing plate 25 and the sliding plate 24 downward, causing the connecting rod 23 to push the clamping plate 22 closer to the test tube, clamping and limiting the test tube placed on the inner side.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
