Description

Technical Field

[0001] This utility model belongs to the field of laboratory equipment technology, specifically designing a drying rack for laboratory equipment. Background Technology

[0002] After washing and cleaning, laboratory equipment such as test tubes are usually dried by air drying. This method consumes no energy, but it takes a lot of time for the equipment to dry completely, which affects the rapid turnover of the equipment.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN218722752U discloses an intelligent test tube dryer. By inserting the test tube with its opening facing down onto a test tube placement column, hot air flows from inside the column, thus achieving the drying of the test tube. The test tube placement column has a hollow tube structure, and the airflow is ejected from the end of the test tube placement column and enters the interior of the test tube. If the airflow is too strong, it will push the test tube to move and fall off the test tube placement column, causing damage to the test tube. If the airflow is too weak, it will affect the drying efficiency of the test tube.

[0004] Therefore, it is necessary to design a drying rack that can improve the drying efficiency of test tubes while avoiding damage to the test tubes to solve the current technical problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drying rack for laboratory equipment that can improve the drying efficiency of test tubes while avoiding damage to them.

[0006] The technical solution of this utility model is as follows: a drying rack for experimental equipment, including a base, on the top of which air blowing pipes are uniformly and vertically arranged; inside the base is a hot air supply assembly connected to the bottom end of the air blowing pipes; a test tube clamp for holding or releasing test tubes is fitted on the outside of the air blowing pipes; the test tube clamp is fixedly mounted above the base; the test tube clamp has a support ring, inside which two clamping blocks are symmetrically arranged; on the opposite side of the two clamping blocks, clamping plates are fixedly arranged; on the corresponding side of the two clamping plates, guide rods are staggered around the perimeter; the guide rods pass through the support ring and are slidably connected to it; a pressing plate is fixedly arranged on the end of the guide rod opposite to the clamping plate; the pressing plate provides elastic support between itself and the support ring.

[0007] The hot air supply assembly has an air duct disposed inside the base. A heating wire and a fan are sequentially disposed at the lower end of the air duct, and the bottom end of the air blowing pipe is connected to the top end of the air duct.

[0008] The upper outer side of the air blowing tube is fitted with an elastic tube head, which is a cylindrical structure made of silicone material.

[0009] The base is provided with a U-shaped support frame at the top, and the support ring is fixedly installed in the support frame.

[0010] The outer side of the support ring is provided with a boss corresponding to the pressing plate. A spring is provided between the pressing plate and the boss. A spring support block matching the end of the spring is provided on both the pressing plate and the boss.

[0011] The clamping block has an arc-shaped surface on the side opposite to the clamping plate that fits against the outside of the test tube.

[0012] The clamping block is a one-piece structure made of silicone material and is bonded to one side of the clamping plate.

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

[0014] (1) In this utility model, when drying the test tube, the test tube is fitted with the opening facing downwards on the outside of the blowing tube, so that the end of the blowing tube abuts against the bottom of the test tube. Then, the test tube is slightly lifted and clamped in the test tube clamp. The clamping force applied to the test tube by the test tube clamp can ensure the stability of the test tube during the drying process, withstand the large airflow blown out by the blowing tube, improve the drying efficiency, and at the same time prevent the test tube from falling off and being damaged.

[0015] (2) By pressing or releasing the pressing plate, the two clamps can be controlled to move away or closer, thereby quickly releasing and clamping the test tube, improving the convenience of test tube assembly and disassembly. Attached Figure Description

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the present invention or its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0021] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1 and 2 As shown, the experimental drying rack includes a base 1. Air blowing pipes 2 are evenly and vertically arranged on the top of the base 1. A hot air supply component 6, connected to the bottom end of the air blowing pipes 2, is located inside the base 1. A test tube clamp 4, used to hold or release test tubes, is fitted onto the outside of the air blowing pipes 2. The test tube clamp 4 is fixedly mounted above the base 1. When drying test tubes, the test tube opening is placed downwards on the outside of the air blowing pipe 2, so that the end of the air blowing pipe 2 abuts against the bottom of the test tube. Then, the test tube is slightly lifted and clamped in the test tube clamp 4. The clamping force applied by the test tube clamp 4 ensures the stability of the test tube during the drying process, allowing it to withstand the large airflow from the air blowing pipe 2, improving drying efficiency, and preventing the test tube from falling off and being damaged. The slight lifting and clamping is to leave a gap between the end of the air blowing pipe 2 and the bottom of the test tube for airflow. During implementation, the lifting height can be controlled to approximately 0.5 cm.

[0023] In the above embodiments, as a specific implementation of the test tube clamp 4, such as Figure 2As shown, the test tube clamp 4 has a support ring 41. Two clamping blocks 42 are symmetrically arranged inside the support ring 41. A clamping plate 42 is fixedly installed on each of the opposite sides of the two clamping blocks 42. Guide rods 45 are staggered around the corresponding sides of the two clamping plates 42. The guide rods 45 pass through the support ring 41 and are slidably connected to it. A pressing plate 47 is fixedly installed on the end of the guide rod 45 opposite to the clamping plate 42. The pressing plate 47 provides elastic support to the support ring 41. Pressing the pressing plate 47 towards the support ring 41 simultaneously... The pressure plate 47 pushes the clamping plate 42 to move through the guide rod 45 connected to it. The clamping plate 42 causes the two clamping blocks 43 to open away from each other. At this time, the test tube is inserted with the opening facing down between the two clamping blocks 43. The pressure plate 47 is released and reset under the action of elasticity. At the same time, it causes the clamping blocks 43 to move closer to each other and hold the test tube tightly. By pressing or releasing the pressure plate 47, the two clamping blocks 43 can be controlled to move away from or closer to each other, thereby realizing the quick release and clamping of the test tube and improving the convenience of test tube assembly and disassembly.

[0024] In some embodiments, such as Figure 3 As shown, in one specific embodiment of the hot air supply component 6, the hot air supply component 6 has an air duct 63 disposed inside the base 1. The lower end of the air duct 63 is sequentially provided with an electric heating wire 62 and a fan 61. The bottom end of the air blowing pipe 2 is connected to the top end of the air duct 63. The electric heating wire 62 heats up after being energized. After the fan 61 is started, it drives the air to flow. The electric heating wire 62 heats the airflow. The heated airflow flows into the air blowing pipe 2 from the air duct and is sprayed out from the upper end of the air blowing pipe 2 to dry the test tube. A temperature sensor can be installed inside the air duct 63 to provide feedback and adjust the electric heating wire 62 to stabilize the drying temperature.

[0025] In some embodiments, such as Figure 4 As shown, an elastic tube head 5 is fitted on the outer side of the upper end of the air blowing tube 2. The elastic tube head 5 is a cylindrical structure made of silicone. During the process of fitting the test tube onto the air blowing tube 2, in order to avoid the upper end of the air blowing tube 2 colliding with the inner bottom of the test tube and damaging the test tube, the elastic tube head 5 can contact the inner bottom of the test tube during the fitting process, which plays a buffering role and avoids collision and damage to the test tube.

[0026] In some embodiments, a gate-shaped support frame 3 is provided on the top of the base 1, with both ends of the support frame 3 fixedly disposed on the top of the base 1, and a support ring 41 fixedly disposed in the support frame 3.

[0027] In some embodiments, a boss 44 corresponding to the pressing plate 47 is provided on the outer side of the support ring 41. A spring 46 is provided between the pressing plate 47 and the boss 44. A spring support block 48 matching the end of the spring 46 is provided on both the pressing plate 47 and the boss 44. The spring 46 provides elastic support between the pressing plate 47 and the boss 44. The spring support block 48 plays a limiting role at both ends of the spring 46, fixing both ends of the spring 46 between the pressing plate 47 and the boss 44.

[0028] In some embodiments, the clamping block 43 has an arc-shaped surface 431 on the side opposite to the clamping plate 41 that fits against the outside of the test tube. The arc-shaped surface 431 allows the clamping block 43 to fit well against the outside of the test tube and ensures stable clamping.

[0029] In some embodiments, the clamp 43 is an integral structure made of silicone material and is bonded to one side of the clamp 42.
