Description

Technical Field

[0001] This utility model relates to the field of laboratory testing, and in particular to a testing rack for laboratory testing. Background Technology

[0002] Laboratory testing is a broad concept that encompasses a variety of analytical, measurement, testing, or diagnostic processes conducted in a controlled environment to obtain scientific information about samples, materials, products, environments, or organisms. These tests can be applied in many fields, including medicine, biology, chemistry, environmental science, food safety, and drug development. Test tubes are generally used to test samples, and test racks are needed to place the test tubes for convenient testing.

[0003] A laboratory testing rack disclosed in Chinese Patent Publication No. CN219559672U includes a base and an adjustment assembly. The adjustment assembly includes a sleeve, an adjustment rod, a horizontal plate, an electric push rod, and a connecting block. This laboratory testing rack, through the coordinated use of the sleeve, adjustment rod, electric push rod, connecting block, and horizontal plate, achieves height adjustment. By activating the electric push rod to push the horizontal plate upwards, the testing rack is moved to a specified height. This allows for easy adjustment to the desired height according to the user's needs, minimizing the inconvenience of bending over or standing on tiptoe to adjust the rack. This makes the testing rack more convenient to use and facilitates better testing of items, thereby improving work efficiency and enhancing the practicality of the testing rack.

[0004] However, when the above-mentioned device tests multiple test tubes, after one test tube is tested, the test tube must be removed and another test tube installed for testing, which is inefficient and affects the progress of the experiment. Utility Model Content

[0005] The purpose of this invention is to provide a testing rack for laboratory testing, which has the advantages of facilitating continuous testing of multiple test tubes and improving the efficiency of laboratory testing.

[0006] The purpose of this utility model is to provide a laboratory testing rack, including a base plate, a gear rotatably connected to the surface of the base plate, a handle meshing with the surface of the gear, the handle rotatably connected to the inner wall of the base plate, a turntable fixedly connected to one end of the gear, testing holes being opened on the surface of the turntable, a placement rack being slidably connected to each testing hole, a clamping mechanism being fixedly connected to the inner wall of each placement rack, limit posts being fixedly connected to both sides of the outer wall of the placement rack, the limit posts being slidably connected to the surface of the turntable, and wheels being rotatably connected to the bottom of each placement rack.

[0007] Furthermore, the clamping mechanism includes a fixed plate, which is fixedly connected to the inner wall of the placement rack. Each fixed plate has a pressing column slidably connected to its inner wall. Each pressing column has a pressure plate fixedly connected to one end. Each fixed plate has a clamping plate rotatably connected to both sides. Each clamping plate has an anti-slip plate fixedly connected to one end of its inner side wall.

[0008] Furthermore, a lifting block is fixedly connected above the base plate. The lifting block is arc-shaped, and its surface contacts the surface of the wheel.

[0009] Furthermore, the racks are arranged in a ring array on the turntable surface, with the wheels contacting the base plate surface below.

[0010] Furthermore, grooves are provided on both sides of the placement rack, and the grooves correspond to both sides of the clamping plate.

[0011] Furthermore, the clamping plate is curved below, and the pressure plate contacts the curved surface below the clamping plate.

[0012] The working principle and usage principle of this utility model are as follows: A test tube is placed in the placement rack, and the test tube contacts the pressing column, causing the pressing column to slide against the inner wall of the fixed plate. This causes the pressing column to move the pressure plate, which in turn contacts the clamping plate. The clamping plate then flips on both sides of the fixed plate, causing the other end of the clamping plate to move the anti-slip plate to clamp the surface of the test tube, thus fixing the test tube securely and facilitating testing. Rotating the handle causes the handle to drive the gear to rotate, which in turn drives the turntable to rotate. The turntable then moves the placement rack, causing the wheels to move on the base plate. When the wheels reach the lifting block, they move the placement rack upwards along the inner wall of the turntable. Simultaneously, the placement rack moves the limiting column along the turntable surface, causing the placement rack to move the test tube upwards, allowing for the testing of the contents of the test tube. This facilitates continuous testing of multiple test tubes, improving the efficiency of laboratory testing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the test tube is placed in the placement rack, the clamping mechanism clamps and fixes the test tube, the hand is rotated, the hand drives the gear to rotate, the gear drives the turntable to rotate, the turntable drives the placement rack to move, the placement rack drives the wheels to move on the surface of the base plate, when the wheels reach the surface of the lifting block, the wheels drive the placement rack to move upward on the inner wall of the turntable, at the same time the placement rack drives the limiting post to slide on the surface of the turntable, the placement rack drives the test tube to move upward, and the contents of the test tube are tested. This facilitates continuous experimental testing of multiple test tubes and improves the efficiency of laboratory testing.

[0014] 1. Compared with the existing technology, this utility model has the advantage of facilitating continuous experimental testing of multiple test tubes and improving the efficiency of laboratory testing.

[0015] 2. Compared with the prior art, this utility model has the advantages of facilitating the stabilization of test tubes and making testing easier. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0023] A laboratory testing rack according to this specific embodiment, such as Figure 1-5 As shown, a laboratory testing rack includes a base plate 1 for stabilizing the device. A gear 2 is rotatably connected to the surface of the base plate 1, and a handle 3 meshes with the surface of the gear 2, driving the gear 2 to rotate. The handle 3 is rotatably connected to the inner wall of the base plate 1. A turntable 4 is fixedly connected to one end of the gear 2, driving the turntable 4 to rotate. Testing holes are provided on the surface of the turntable 4, and a placement rack 5 is slidably connected to each testing hole. The placement rack 5 facilitates the stabilization of test tubes. Clamping devices are fixedly connected to the inner wall of the placement rack 5. The mechanism clamps and fixes the test tubes. Limiting posts 6 are fixedly connected to both sides of the outer wall of the placement rack 5. The limiting posts 6 drive the placement rack 5 to slide on the inner wall of the turntable 4. The limiting posts 6 are all slidably connected to the surface of the turntable 4. Wheels 7 are rotatably connected to the bottom of the placement rack 5. The wheels 7 can move on the surface of the base plate 1. Lifting blocks 8 are fixedly connected to the top of the base plate 1. The lifting blocks 8 are arc-shaped. The surface of the lifting blocks 8 contacts the surface of the wheels 7. The placement rack 5 is arranged in a ring on the surface of the turntable 4. The wheels 7 are in contact with the surface of the base plate 1.

[0024] Through the above technical solution, multiple test tubes are placed in the placement rack 5, and the clamping mechanism clamps and fixes the test tubes. Rotating the handle 3 causes the handle 3 to drive the gear 2 to rotate, which in turn drives the turntable 4 to rotate. The turntable 4 then moves the placement rack 5, causing the placement rack 5 to move the wheels 7 on the surface of the base plate 1. When the wheels 7 reach the surface of the lifting block 8, the wheels 7 drive the placement rack 5 to move upward on the inner wall of the turntable 4. At the same time, the placement rack 5 drives the limiting post 6 to slide on the surface of the turntable 4, causing the placement rack 5 to move the test tubes upward, thus allowing for the detection of the items inside the test tubes. This facilitates continuous experimental testing of multiple test tubes and improves the efficiency of laboratory testing.

[0025] like Figure 1-5 As shown, the clamping mechanism includes a fixed plate 11, which is fixedly connected to the inner wall of the placement rack 5. Each fixed plate 11 has a pressing post 12 slidably connected to its inner wall. Each pressing post 12 has a pressure plate 13 fixedly connected to one end. Each fixed plate 11 has a clamping plate 14 rotatably connected to both sides. Each clamping plate 14 has an anti-slip plate 15 fixedly connected to one end of its inner side wall. Each side of the placement rack 5 has a through groove, which corresponds to both sides of the clamping plate 14. The lower part of the clamping plate 14 is curved. The pressure plate 13 contacts the curved surface of the lower part of the clamping plate 14. The anti-slip plate 15 increases the friction with the test tube and prevents the test tube from sliding.

[0026] With the above technical solution, when the test tube is placed on the inner wall of the placement rack 5, the test tube contacts the pressing column 12, causing the pressing column 12 to slide on the inner wall of the fixing plate 11. The pressing column 12 drives the pressure plate 13 to contact the clamping plate 14 and move, causing the clamping plate 14 to flip on both sides of the fixing plate 11. At the same time, the clamping plate 14 slides in the through grooves opened on both sides of the placement rack 5, causing the other end of the clamping plate 14 to drive the anti-slip plate 15 to clamp the surface of the test tube, thus fixing the test tube and facilitating its stability for testing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
