Technical Field

[0001] The present application relates to the technical field of test tube fixing devices, and in particular to a detachable test tube clamping seat. Background Art

[0002] In testing laboratories, test tubes are the most commonly used instruments. When conducting quality inspections on soil and water resources, test tubes containing samples usually need to be placed in a cooking container for cooking. At present, laboratories use ordinary test tube racks to place test tubes, but they cannot play a fixed role. During the cooking process, the test tubes are prone to shaking, causing the samples in the test tubes to shake. For this reason, the existing method is to bundle multiple test tubes with rubber bands and then place them in a cooking container, so that the test tubes are not shaken. However, the bundling method is very inconvenient for operators and requires two people to complete the operation, which is time-consuming and laborious. Utility Model Content

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] Example

[0018] In order to solve the above technical problems, this embodiment provides a detachable test tube clamping seat, such as Figure 1-2The invention comprises a base 10, a fixed plate 30 arranged in the middle of the base 10, a clamping assembly 20 is slidably arranged on both sides of the base 10 located at the fixed plate 30, the clamping assembly 20 can move towards or away from the fixed plate 30, a plurality of arc grooves 40 are provided on the surface of the clamping assembly 20 opposite to the fixed plate 30, and then the test tube containing the sample is placed between the fixed plate 30 and the clamping assembly 20, by driving the clamping assembly 20 close to the fixed plate 30, and then clamping the test tube through the arc groove 40, test tubes of different sizes can be clamped, and compatibility is improved. A locking member 50 threadedly connected to the fixed plate 30 is inserted on the clamping assembly 20, and then the clamping force between the fixed plate 30 and the clamping assembly 20 can be adjusted through the locking member 50, so as to ensure that the test tube can be fixed while preventing the clamping force from being too large and crushing the test tube, the operation is simple and convenient, saving manpower, and can ensure that the test tube will not shake during the experiment.

[0019] Specifically, the clamping assembly 20 includes a slide plate 21 slidably arranged on the base 10, columns 22 arranged on both sides of the slide plate 21, and a clamp plate 23 fixed on the top of the column 22, and an arc groove 40 is provided on the side of the clamp plate 23 facing the fixed plate 30. After the test tube is placed in place, the slide plate 21 is driven to move toward the fixed plate 30, and then the clamp plate 23 and the arc groove 40 on the fixed plate 30 clamp and fix the test tube, and then the fixed plate 30 and the clamping assembly 20 are relatively fixed by the locking member 50, and the clamping force ensures that the test tube does not shake. It should be noted that in the above scheme, an arc groove 40 is used instead of a semicircular groove, and the semicircular groove cannot achieve the clamping effect. The clamping method using the arc groove 40 can clamp test tubes of different sizes, thereby improving compatibility.

[0020] Furthermore, in order to enable the slide plate 21 to slide on the base 10, a T-shaped groove 12 is provided on the surface of the base 10, and a slider that slides in the T-shaped groove 12 is provided on the bottom surface of the slide plate 21. Then, the slide plate 21 slides in the T-shaped groove 12 through the slider to loosen or clamp the test tube and realize an overall detachable structure.

[0021] Furthermore, in order to prevent the fixing plate 30 and the clamping assembly 20 from scratching the surface of the test tube when clamping the test tube, a soft rubber pad 41 is provided on the inner wall of the arc groove 40. The soft rubber pad 41 is made of a high temperature resistant plastic material and will not shrink or deform in a high temperature environment. The soft rubber pad 41 will not damage the surface of the test tube when contacting the test tube. Among them, the base 10, the fixing plate 30 and the clamping assembly 20 are all made of a high temperature resistant plastic material and will not deform in a high temperature environment.

[0022] In order to achieve relative fixation of the fixing plate 30 and the clamping assembly 20, further, a locking member 50 is passed through the column 22 and is threadedly connected to the fixing plate 30. The locking member 50 is a bolt, and the clamping force is adjusted by adjusting the tightness of the bolt.

[0023] Furthermore, when the test tube is placed between the fixing plate 30 and the clamping assembly 20, in order to preliminarily position the test tube, a placement groove 11 is correspondingly provided below the arc groove 40 on the base 10. The placement groove 11 is larger than the diameter of the test tube so as to be compatible with test tubes of different sizes. The bottom of the test tube in this solution is flat, so the placement groove 11 is a flat bottom sink, and the test tube is preliminarily positioned before clamping. In other embodiments, when the bottom of the test tube is round, the placement groove 11 can be designed as a round bottom.

[0024] Further, such as Figure 3 As shown, a through hole 13 connected to the T-shaped chute 12 and the placement groove 11 is opened on the bottom surface of the base 10. After the entire clamping seat is placed in a container for cooking, water will inevitably accumulate in the T-shaped chute 12 and the placement groove 11 when it is taken out. Therefore, when the entire clamping seat is lifted, the through hole 13 can achieve the purpose of drainage.

[0025] Further, a plurality of support rods 60 are provided on one side of the slide plate 21. After the test is completed and the test tube is sterilized by boiling, the test tube can be inverted on the support rods 60, thereby achieving the purpose of drying and storing the test tube.

[0026] To summarize, the present application scheme is to set a fixed plate in the middle of the base, and clamping assemblies are slidably set on both sides of the base located on the fixed plate, the clamping assembly can move toward or away from the fixed plate, and a plurality of arc grooves are opened on the surface of the clamping assembly opposite to the fixed plate, so that the test tube containing the sample is placed between the fixed plate and the clamping assembly, and the clamping assembly is driven close to the fixed plate, and the test tube is clamped through the arc groove, and a locking piece threadedly connected to the fixed plate is inserted on the clamping assembly, and the clamping force between the fixed plate and the clamping assembly can be adjusted through the locking piece to ensure that the test tube can be fixed while preventing the clamping force from being too large and crushing the test tube. The operation is simple, convenient, manpower-saving, and can ensure that the test tube will not shake during the experiment.

[0027] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
