Description

Technical Field

[0001] The utility model relates to the technical field of metal detection tools, in particular to a metal detection test tube storage structure. Background Art

[0002] Due to the increasing mining, smelting, processing and commercial manufacturing activities of heavy metals, a lot of heavy metals such as lead, mercury, tin, etc. have entered the atmosphere, water and soil environment, causing serious environmental pollution. These heavy metals can indirectly enter the human body through food, causing heavy metal poisoning. Therefore, heavy metal testing of water quality and soil is particularly important. During outdoor testing, testers need to carry test kits to the area to be tested. The test kits contain reaction reagents, test tubes, standard color cards, reaction tubes, etc. for testing. However, most existing test kits are paper-based and are easily damaged during outdoor movement, resulting in the spillage of reaction reagents and even the breakage of test tubes or reaction tubes, affecting the progress of heavy metal testing.

[0003] In order to improve the above-mentioned disadvantages, the utility model patent authorized by the public account CN214844729U discloses a metal detection kit for heavy metal detection, including an aluminum alloy shell, a fixed bracket movably connected inside the aluminum alloy shell, the fixed bracket including a fixed horizontal plate, and a frame-shaped plug-in block is provided at the bottom of the fixed horizontal plate. Although the reaction tubes and test tubes can be properly placed through the test tube rack, the stability of the test tubes required for metal detection is poor after placement. During outdoor movement, the test tubes are prone to collision with the test tube rack, and the probability of damage to the test tubes required for metal detection is high, affecting the normal progress of the metal detection operation. Utility Model Content

[0004] The purpose of the present utility model is to provide a metal detection test tube storage structure to solve the problem proposed in the above-mentioned background technology that the test tubes required for metal detection have poor stability after placement, and are prone to collision between the test tubes and the test tube racks during outdoor movement, resulting in a high probability of damage to the test tubes required for metal detection, thereby affecting the normal progress of metal detection operations.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a metal detection test tube storage structure, including a test tube rack, wherein the upper surface of the test tube rack is evenly provided with a plurality of placement cavities, a stabilization unit is provided inside the placement cavity, and both ends of the outer wall of the test tube rack are fixedly connected with a slide bar, and the stabilization unit includes a splint, a support plate, a transverse groove, a rack plate, a tooth column, a rotating rod, a knob, a spring, a sleeve and a square rod, and the two splints are respectively located on both sides of the interior of the placement cavity, and the front surface of the splint is fixedly connected with a support plate, and the support plate is connected to the front surface of the splint. The cross groove is slidably connected to the test tube rack, and the outer surface of the support plate is fixedly connected to a rack plate, and a tooth column is meshed and connected between the two rack plates. The inner wall of the tooth column is fixedly connected to a rotating rod, and the front end of the rotating rod is fixedly connected to a knob. A spring is provided on the front and back sides of the tooth column, and the inner ring of the spring is fixedly connected to the rotating rod. The outer ring of the spring is fixedly sleeved with a sleeve, and the sleeve is fixedly connected to the contact surface of the test tube rack. A square rod is provided on the inner wall of the rack plate, and one end of the square rod is fixedly connected to the contact surface of the test tube rack.

[0006] Preferably, the center points of the knob, the rotating rod and the tooth column are all located on the same horizontal vertical line.

[0007] Preferably, a force-applying unit is provided on one side surface of the splint, and the force-applying unit includes a push rod, a rubber head, a slot and a compression spring. A plurality of push rods are evenly inserted into one side surface of the splint, and the outer end of the push rod is fixed with a rubber head. The push rod is plugged into the splint through a slot, and a compression spring is provided inside the slot. The two ends of the compression spring are respectively fixedly connected to the contact surfaces of the push rod and the splint.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the metal detection test tube storage structure has the following advantages over the traditional technology:

[0009] Through the cooperation between the test tube rack, the placement chamber, the stabilization unit and the slide bar, first, force is applied to the knob to rotate the rotating rod and the tooth column. The rotation of the tooth column can engage the rack plate, which can increase the distance between the two support plates and the two splints. At this time, the metal detection test tube to be placed is placed between the two splints inside the placement chamber, and then the force on the knob is slowly released. During this process, the spring rebounds, the tooth column rotates in the opposite direction mentioned above, and the two splints move toward each other, clamping the placed metal detection test tube, greatly increasing the stability between the test tube and the test tube rack. In the subsequent outdoor movement, the test tube and the test tube rack are less likely to collide, which can greatly reduce the chance of test tube damage and ensure the normal progress of subsequent metal detection operations.

[0010] Through the cooperation between the test tube rack, the placement cavity, the stabilization unit, the slide bar and the force-applying unit, when the splint moves toward the placement cavity to place the test tube, multiple rubber heads will successively press against the outer wall of the test tube, and multiple support rods will slide a certain distance into the slot. The compression spring is in a compressed state, and the contact and pressing points between the multiple rubber heads and the outer wall of the test tube will form an arc surface that fits the outer wall of the test tube, which can facilitate the proper pressing of the outer walls of test tubes of different sizes, and has a wide range of applications.
