Description

Technical Field

[0001] The utility model relates to the technical field of laboratory equipment, in particular to a test tube rack with a drying function. Background Art

[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. Test tubes are divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. Test tubes need to be dried after cleaning. At present, most of the test tube drying processes still use natural air drying or manual wiping, and then place the test tubes on the test tube rack. This is time-consuming, labor-intensive, and inefficient, and the drying effect of the test tubes is not good, which indirectly affects the efficiency of experimental operations.

[0003] The existing test tube rack does not have a drying function, the drying efficiency of the test tube is low, and the drying effect is poor. This solution solves this technical problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a test tube rack with a drying function.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a test tube rack with a drying function, comprising a base, a plurality of hollow tubes arranged in an array on the base, a limit assembly sleeved on the outer side of the hollow tube, a test tube being arranged between the hollow tube and the limit assembly in a liftable manner, the edge of the test tube being detachably abutted against the limit assembly, an exhaust hole group being arranged on the top side of the hollow tube, an air pump being connected to the bottom end of the hollow tube, and an electric heating wire being connected to the air inlet of the air pump;

[0006] The limiting assembly includes an annular support sleeved on the outside of the test tube, and a plurality of rubber blocks swingably arranged on the inside of the annular support. A connecting piece is arranged at the bottom end of one side of the rubber block, and the connecting piece is connected to the annular support. The other side of the rubber block is detachably abutted against both sides of the edge of the test tube.

[0007] The exhaust hole group includes a top hole arranged at the top end of the hollow tube and side holes arranged in an array at the side of the hollow tube.

[0008] A plurality of vertical supports are arranged in an array outside the annular support, and the other ends of the vertical supports are connected to the base.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The air pump sprays hot air into the hollow tube, and the airflow is discharged through the top hole and the side hole to blow the rising test tube. On the one hand, the excess water in the test tube is blown out by the airflow, and on the other hand, the inner wall of the test tube is dried, avoiding the residual water stains in the test tube. The drying and cleaning efficiency of the test tube is higher and the effect is better;

[0011] (2) A limit assembly is provided. When the test tube is dried, the edge of the test tube abuts against the rubber block of the limit assembly when the test tube is raised, thereby preventing the test tube from falling out. The test tube can be removed by holding it, making the drying of the test tube safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0021] See also Figure 1-Figure 7A test tube rack with a drying function comprises a base 1, a plurality of hollow tubes 2 arranged in an array on the base 1, a limiting assembly 3 sleeved on the outer side of the hollow tube 2, a test tube 4 is arranged between the hollow tube 2 and the limiting assembly 3 in a liftable manner, the edge of the test tube 4 is detachably abutted against the limiting assembly 3, an exhaust hole group is arranged on the top side of the hollow tube 2, an air pump 5 is connected to the bottom end of the hollow tube 2, an electric heating wire is connected to the air inlet of the air pump 5, and a power switch is connected to the air pump 5 and the electric heating wire;

[0022] The limiting assembly 3 includes an annular support 31 sleeved on the outside of the test tube 4, and a plurality of rubber blocks 32 swingably arranged on the inside of the annular support 31. A connecting piece 321 is arranged at the bottom end of one side of the rubber block 32, and the connecting piece 321 is connected to the annular support 31. The other side of the rubber block 32 is detachably abutted against the two sides of the edge of the test tube 4.

[0023] The exhaust hole group includes a top hole 6 arranged at the top end of the hollow tube 2 and side holes 7 arranged in an array at the side of the hollow tube 2 .

[0024] A plurality of vertical supports 8 are arranged in an array outside the annular support 31 , and the other ends of the vertical supports 8 are connected to the base 1 .

[0025] The base 1 is provided with a drainage groove facing the opening side of the test tube 4, through which the excess water discharged from the inverted test tube 4 is drained away.

[0026] The specific working process of this utility model:

[0027] When using, see Figure 6 , invert the test tube 4 and gradually insert it into the outside of the hollow tube 2. At this time, the edge of the test tube 4 abuts against the rubber block 32 of the limit assembly 3, so that the rubber block 32 swings downward and deforms. When the edge of the test tube 4 completely passes through the rubber block 32, the rubber block 32 is reset. At this time, the inner bottom of the test tube 4 is close to the top hole 6 and the side hole 7 at the top of the hollow tube 2;

[0028] Turn on the power switches of the air pump 5 and the electric heating wire. The air pump 5 starts and blows the airflow heated by the electric heating wire into the hollow tube 2. The airflow is discharged through the top hole 6 and the side hole 7. The airflow from the top hole 6 gradually lifts up the test tube 4, blows out the remaining water at the bottom of the test tube 4 and dries it, and then blows the side wall of the test tube 4 through the side hole 7 and dries it. Figure 7 When the test tube 4 is lifted up by the reaction force generated by the ejected airflow and rises to the outer edge and abuts against the rubber block 32, the rubber block 32 is supported by the annular support 31, and the reaction force of the airflow on the test tube 4 is smaller than the supporting force of the rubber block 32 on the edge of the test tube 4. The test tube 4 is confined at the rubber block 32, and the hot air blown by the air pump 5 and the electric heating wire completes the discharge of excess water in the test tube 4, and also completes the drying of the test tube 4, ensuring the cleanliness of the test tube 4;

[0029] When the water on the inner wall of the test tube 4 is drained and dried, the power switch is turned off, the air pump 5 and the electric heating wire stop running, and then the test tube 4 is held by hand to overcome the restraining force of the rubber block 32, and the test tube 4 can be drawn out of the limit assembly and used.

[0030] By opening a top hole 6 and a side hole 7 on the hollow tube 2, when the heated airflow passes through the hollow tube 2, on the one hand, the excess moisture in the test tube 4 is blown out by the airflow, and on the other hand, the inner wall of the test tube 4 is dried, thereby avoiding residual water stains in the test tube 4, and the drying and cleaning effects of the test tube 4 are better.

[0031] Technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be elaborated here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
