Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment, and in particular to a test tube clamp. Background Technology

[0002] A dry thermostat, also known as a constant-temperature metal bath or dry thermostat, is a temperature-controlled device using microcomputer control and semiconductor refrigeration technology. It is a commonly used instrument in biochemistry experiments. Test tubes containing reagents are typically arranged in an array on a test tube box, and then staff members remove them one by one and transfer them to the dry thermostat. Since a dry thermostat can process dozens of test tubes simultaneously, manually handling them would significantly increase the workload for staff and result in extremely low efficiency. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a test tube clamp that is simple in structure, convenient and practical, reducing the labor intensity of staff and improving experimental efficiency.

[0004] This utility model is achieved by the following scheme: a test tube clamp, including a butterfly clamp, the butterfly clamp including a first clamp body and a second clamp body, the inner sides of the clamping parts of the first clamp body and the second clamp body are respectively fixedly connected to clamping plates, and the clamping surfaces of the clamping plates are evenly distributed with a plurality of arc-shaped grooves that can be adapted to the test tubes, the arc-shaped grooves on the two clamping plates correspond one to one and the openings face each other.

[0005] Furthermore, the first clamping body is provided with a first handle in the middle, and the second clamping body is provided with a second handle in the middle. The first handle and the second handle are hinged together by a pin. A torsion spring is sleeved on the pin. The two ends of the torsion spring abut against the inner sides of the first handle and the second handle respectively so that the first handle and the second handle can be opened and the first clamping body and the second clamping body can be clamped.

[0006] Furthermore, the inner sides of the first handle and the second handle are respectively provided with hinged ear plates that are hinged together by the pin.

[0007] Furthermore, a rubber pad is provided in the arc-shaped groove of the clamping plate.

[0008] Compared with the prior art, the present invention has the following advantages: The test tube clamp of the present invention has a simple structure, reasonable design, and is convenient and practical. It can pick up a whole row of test tubes on the test tube box at a time, avoiding the tedious process of picking them up one by one manually. This directly reduces the labor intensity of the staff and improves the efficiency of the experiment.

[0009] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through specific embodiments and related drawings. Attached Figure Description

Detailed Implementation

[0011] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0012] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0013] like Figures 1-4 As shown, a test tube clamp includes a butterfly clamp 100, which comprises a first clamping body 110 and a second clamping body 120. Clamping plates 130 are fixedly connected to the inner sides of the clamping portions of the first and second clamping bodies, respectively. Several arc-shaped grooves 131, which adapt to the test tubes, are evenly distributed on the clamping surface of the clamping plates 130. The arc-shaped grooves 131 penetrate the upper and lower sides of the clamping plates, and the arc-shaped grooves on the two clamping plates correspond one-to-one and their openings face each other. Using this test tube clamp, an entire row of test tubes on a test tube box can be picked up at once, avoiding the tedious process of manually picking them up one by one. This directly reduces the labor intensity of the staff and improves experimental efficiency. The spacing of the arc-shaped grooves is the same as the spacing of the slots for placing test tubes on the test tube box and the dry thermostat, ensuring that the arc-shaped grooves correspond one-to-one with the position of the entire row of test tubes. The clamping plates on both sides hold the upper end of the test tubes, and through the action of the limiting grooves, the angle of the test tubes is prevented from deflecting during clamping or transfer, maintaining an upright state.

[0014] In this embodiment, the first clamping body has a first handle 140 in the middle, and the second clamping body has a second handle 150 in the middle. The first handle and the second handle are hinged together by a pin. A torsion spring 170 is sleeved on the pin. The two ends of the torsion spring abut against the inner surfaces of the first handle and the second handle, respectively, so that the first handle and the second handle can be opened while the first clamping body and the second clamping body clamp together. When the user squeezes the two handles, the torsion spring is compressed, and the two clamping bodies open; when the handles are released, the clamping bodies automatically clamp together.

[0015] In this embodiment, the inner sides of the first handle and the second handle are respectively provided with hinged ear plates 160 that are hinged together by the pin.

[0016] In this embodiment, a rubber pad 180 is provided in the arc-shaped groove of the clamping plate to provide a cushioning effect, avoid scratching the outer wall of the test tube, and at the same time enhance the clamping stability to prevent the test tube from falling.

[0017] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0018] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0019] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
