Description

Technical Field

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

[0002] A test tube rack is an instrument used to support test tubes. It typically consists of two parts: a base and a frame. The base secures and supports the frame, while the frame holds the test tubes and maintains their stable position. It is widely used in laboratories (e.g., water analysis in thermal power plants) and medical settings (e.g., blood sample storage).

[0003] Currently, when testing samples in the laboratory, it is often necessary to use test tube racks to temporarily place test tubes containing samples.

[0004] Existing test tube racks have uniformly sized holes that cannot be adjusted, generally only accommodating test tubes of the same diameter. They cannot accommodate larger diameter test tubes. While smaller diameter test tubes can be placed, a significant gap exists between the tube and the inner wall of the holes, causing the tubes to wobble and increasing the risk of damage when the rack is moved. Furthermore, laboratory sample testing often involves test tubes of varying sizes. If two or more different sizes of test tubes are needed for the same batch of tests, two or more different test tube racks are required, which is cumbersome and inconvenient. Therefore, a new test tube rack is proposed. Utility Model Content

[0005] This utility model is a test tube rack proposed to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a test tube rack, including a main frame, wherein a plurality of screw assemblies are uniformly fixedly connected to one side of the outer surface of the main frame, a connecting block is threaded onto the outer surface of each of the plurality of screw assemblies, and a movable frame is fixedly connected to one side of the outer surface of each of the plurality of connecting blocks.

[0007] Each of the multiple movable frames includes two slides, which are symmetrically slidably inserted into the top of the main frame. Two fixed rods are fixedly connected between the two slides. Multiple left V-shaped clamps are fixedly connected to one side of the outer surface of each of the two fixed rods. A movable frame is slidably connected between the two slides. Multiple right V-shaped clamps are fixedly connected to one side of the outer surface of the movable frame, and the right V-shaped clamps match the left V-shaped clamps. A drive screw is installed between each slide and the movable frame.

[0008] Furthermore, a rubber pad is fixedly installed on the inner bottom of the main frame.

[0009] Furthermore, each of the plurality of screw assemblies includes a mounting base, and the mounting base is fixedly mounted on one side of the outer surface of the main frame. A first screw is rotatably fitted onto the top of the mounting base, and the first screw is threadedly connected to an adjacent connecting block. A knob is fixedly connected to the top of the first screw.

[0010] Furthermore, each of the multiple left V-shaped clamps includes a first fixing block, and the first fixing block is fixedly connected to an adjacent fixing rod, with a first V-shaped clamp fixedly connected to one end of the first fixing block.

[0011] Furthermore, each of the multiple right V-shaped clamps includes a second fixing block, and the second fixing block is fixedly connected to the movable frame, with a second V-shaped clamp fixedly connected to one end of the second fixing block.

[0012] Furthermore, each of the plurality of drive screws includes a second screw, and the second screw is rotatably engaged on one side of the outer surface of an adjacent slide. The movable frame is threaded onto the outer surface of the second screw, and a drive block is fixedly connected to one end of the second screw.

[0013] The beneficial effects of this utility model are:

[0014] In use, this utility model provides a test tube rack that, through a screw assembly, connecting block, slide, fixing rod, left V-shaped clamp, right V-shaped clamp, movable frame, and drive screw, allows for adjustment of the distance and height between the left and right V-shaped clamps according to the height and diameter of the test tubes. This satisfies the requirements for test tube placement and prevents test tubes from shaking. Furthermore, it can simultaneously hold test tubes of various sizes, reducing the amount of test tube rack needed and improving ease of use. Attached Figure Description
