Description

Technical Field

[0001] The present application relates to the technical field of test instruments, and in particular to a test tube with an anti-spill function. Background Art

[0002] In medical testing, test tubes are basic laboratory equipment. When loading, mixing, and storing various reagents or samples, there is a risk of liquid spillage due to improper operation, pressure fluctuations, and other factors. This may not only lead to the loss of precious experimental materials, but also pose a threat to the safety of experimenters and the laboratory environment.

[0003] The main causes of liquid spillage include improper operation, equipment failure, and accidental collision. When performing experimental operations, the slightest carelessness may cause the test tube to tip over or the liquid to splash. For example, during the storage of the test tube, if it is not properly handled, the test tube may be bumped or shaken, which may also cause liquid spillage. This may cause spillage accidents.

[0004] Liquid spillage not only causes waste of experimental materials and increases experimental costs, but may also bring a series of safety hazards. Some chemical reagents are corrosive, toxic or radioactive. If they spill, they will not only pollute the experimental environment, but also pose a serious threat to the health of the experimenters. For biological experiments, spilled samples may contain pathogens or other harmful substances, leading to increased laboratory biosafety risks. Summary of the invention

[0005] The technical problem to be solved by the present application is to overcome the existing defects and provide a test tube with an anti-spill function, which can effectively solve the problems in the background technology.

[0010] As a preferred technical solution of the present application, a plug is provided at the end of the test tube.

[0011] Compared with the prior art: the present application can respond to the tilt of the test tube through the combination of the automatic winding group and the hanging ring, effectively preventing the overflow of the experimental liquid. The flow limiting seat is equipped with a spherical baffle and a fine-adjustable pull rope system, so that the liquid can be dumped and sealed in the test tube, which greatly reduces the safety hazards in laboratory operations, protects the health of experimenters and the cleanliness of the laboratory environment. The chamfer of the guide hole not only reduces the liquid flow resistance, but also effectively avoids turbulence and vortexes during the liquid flow process, ensures the smooth outflow of the liquid, reduces splashing during the experiment, and further ensures the cleanliness and safety of the experimental operation.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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 (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] See also Figure 1-3 The present application provides a technical solution: a test tube with an anti-spill function, comprising a test tube placement base 1, a test tube placement seat 6 is provided at the upper end of the test tube placement base 1, and a test tube 7 is sleeved in the test tube placement seat 6.

[0018] The test tube placement base 1 is a support platform for the entire anti-spill test tube system. The test tube placement base 1 is stable and stable, ensuring stable placement on the laboratory table, providing a safe and fixed base, and providing installation space for other auxiliary components such as an automatic winding group.

[0019] The test tube placement seat 6 directly contacts and fixes the test tube. Its inner diameter size can be tightly fitted with the test tube 7, which is neither too loose to cause the test tube to shake, nor too tight to be difficult to insert or remove, further enhancing the stability of the test tube 7 during operation. The test tube 7 is a double-layer structure, which improves the structural strength of the test tube 7, avoids the test tube 7 from being easily broken, and improves the convenience of use.

[0020] An annular sleeve 3 is arranged at the upper end of the outer surface of the test tube 7, an intermediate ring 5 is arranged below the annular sleeve 3, and a hanging ring is arranged on the lower surface of the intermediate ring 5, and the hanging ring is connected to the automatic winding group arranged in the test tube placement base 1.

[0021] The annular sleeve 3 provides an additional fixing point for the test tube 7. After the test tube 7 is subjected to an external force and falls over, the annular sleeve 3 lifts the end of the test tube 7 so that the material flows back to the bottom of the test tube 7 to avoid spilling.

[0022] The middle ring 5 plays the role of connecting and transmitting force. On the one hand, the middle ring 5 is connected to the pull rope 2 connected to the spherical stopper 10, and at the same time, the lifting ring on it is connected to the automatic winding group to ensure a quick response in an emergency (such as the test tube 7 tilting).

[0023] The test tube 7 is physically connected to the automatic winding group through the lifting ring. Once the test tube 7 deviates from the predetermined position or is affected by external force and may cause spillage, the lifting ring will be pulled by the automatic winding group to quickly adjust the test tube 7 back to a safe position.

[0024] When the force transmitted by the lifting ring triggers the automatic reeling group, the spring or cable inside it will respond immediately, tightening the lifting ring through a rapid retraction action, thereby driving the test tube 7 back to an upright or more stable position, effectively preventing liquid from spilling and reducing losses and dangers caused by accidents during the experiment.

[0025] A flow limiting seat 8 is arranged in the test tube 7 , a flow guiding hole 9 is arranged on the flow limiting seat 8 , a spherical baffle 10 is arranged corresponding to the flow guiding hole 9 , one end of the spherical baffle 10 is connected to a pull rope 2 , and the other end of the pull rope 2 is connected to the middle ring 5 .

[0026] The flow limiting seat 8 ensures that the liquid can be effectively controlled when it flows out of the test tube 7 to avoid splashing or waste caused by pouring too fast. The spherical baffle 10 is arranged on the guide hole 9. By pulling or loosening the pull rope 2, the up and down movement of the spherical baffle 10 can be controlled to adjust the opening and closing of the guide hole to avoid spilling.

[0027] Furthermore, ear plates 11 are provided on both sides of the test tube placement base 1, and the ear plates 11 are connected to an external storage rack.

[0028] The ear plates 11 are small extension parts arranged on both sides of the test tube placement base 1, usually in a shape that is easy to fix or hook. The ear plates 11 provide additional fixing points or hanging interfaces for the test tube placement base 1, so that the entire anti-spill test tube device can be more stably integrated with the external rack.

[0029] Furthermore, the test tube 7 adopts a double-layer structure.

[0030] The double-layer structure of the test tube 7 provides additional physical strength and durability. The outer layer can withstand more mechanical stress, such as collision or pressure, and protect the inner layer from damage, thereby extending the service life of the test tube 7 and reducing the risk of breakage during the experiment.

[0031] Furthermore, the lower guide hole 9 on the current limiting seat 8 is provided with a chamfer, and the edge of the chamfer fits with the inner wall of the test tube 7 .

[0032] The chamfer on the guide hole 9 can promote a smooth transition, so that when the liquid passes through the guide hole 9, it can smoothly transition from the relatively spacious space inside the flow limiting seat 8 to the narrower guide hole 9, reducing the resistance to liquid flow and avoiding turbulence or vortex caused by fluid dynamics effects, thereby reducing the possibility of liquid splashing and ensuring the cleanliness and safety of experimental operations.

[0033] Furthermore, a plug 4 is provided at the end of the test tube 7 .

[0034] When in use: Place the anti-spill test tube system on the laboratory table and make sure that the test tube placement base 1 is stable and horizontal. Insert the double-layer test tube 7 vertically into the test tube placement seat 6 to ensure that it is tightly fitted with the test tube placement seat 6, which is both stable and easy to remove. According to the experimental requirements, pre-adjust the position of the spherical baffle 10, and control the opening and closing of the diversion hole 9 by the pull rope 2. If the sample needs to be stored for a long time, use the seal 4 to seal the top of the test tube 7. During operation, if you need to pour or transfer the liquid in the test tube 7, loosen the pull rope 2 on the hanging ring, take out the test tube 7, and operate gently to avoid violent shaking. If the test tube 7 is accidentally tilted, the automatic winding group will immediately pull down the hanging ring, drive the spherical baffle 10 to move, and make the spherical baffle 10 block the diversion hole 9 to reduce the risk of liquid overflow.

[0035] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
