Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and more specifically to a light-proof multifunctional test tube rack. Background Technology

[0002] A test tube rack is a basic chemical laboratory instrument, mainly used for placing, fixing, and drying test tubes. It is a key auxiliary device in chemistry, medicine, and other laboratories to ensure operational safety, improve work efficiency, and maintain the cleanliness of the work area. A typical test tube rack usually consists of an upper plate, a lower plate, and side support plates. Test tubes are inserted into corresponding holes in the upper and lower plates, and the overall structure is open, allowing the test tubes to be fully exposed to ambient light.

[0003] Currently, in hospitals and research laboratories, experiments requiring light protection often involve moving the test tubes to dark places such as drawers or refrigerators after the reaction, or covering them with light-blocking materials. This process is not only cumbersome and prone to interference from frequent refrigerator openings or improper covering, leading to deviations or even failures in experimental results, but also increases the complexity and risk of errors for operators. To address these issues, this study designed a multifunctional test tube rack with light-blocking capabilities. By incorporating a built-in cavity at the bottom of the rack with a foldable light-blocking curtain, it allows for convenient light protection of the test tubes, effectively preventing ambient light interference and improving the reliability and consistency of experimental results. Furthermore, the light-blocking curtain can be quickly retracted when not in use, without affecting the regular use of the test tube rack. This design not only optimizes the simplicity and efficiency of light-blocking operations but also enhances the integration and functionality of laboratory equipment.

[0004] To better prevent test tubes from coming into contact with light and improve the success rate of experiments, Chinese patent application, publication number CN214916348U, discloses a novel light-shielding test tube rack. This utility model includes a rectangular shell with an opening on one side, into which a test tube rack is placed. A light-shielding plate is fixedly connected to one end of the test tube rack. A pulley is provided on each of the two sides of the bottom of the test tube rack, and a corresponding slide rail is provided on the inner surface of the bottom of the shell. The test tube rack is slidably connected to the shell via the pulleys. This utility model is easy to operate, and the all-around light-shielding material reduces sample contact with light. The pull-out design of the test tube rack makes placing and retrieving samples more convenient and faster, reducing the frequency of sample contact with optical fibers. However, this solution still has some shortcomings or areas for improvement in its application. Since test tubes are usually placed in a refrigerator after liquid collection, the test tube rack needs to be small in size to avoid taking up too much space. In addition, the test tube rack needs to be able to switch flexibly between light-protected and light-free experiments and be easy to carry. If it occupies too much space, it will be inconvenient to carry or transport. Therefore, the structure of the test tube rack needs to be improved so that it can be flexibly switched according to experimental needs, while also being easy to carry, avoiding taking up too much space, and further improving the practicality of the test tube rack. Utility Model Content

[0005] The present invention discloses a light-proof multifunctional test tube rack, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A light-shielding multifunctional test tube rack includes a test tube rack body, which includes an upper plate, a lower plate, and side plates. The bottom of the lower plate has a rear groove with an opening facing backward. The lower left and right sides of the rear groove have slide rails, and a three-sided folding light-shielding plate is embedded between the slide rails. The side plates have an upper groove with an opening facing upward. The upper groove contains a liftable light-shielding side plate. The three-sided folding light-shielding plate is pulled out backward and covers the back, top, and front of the test tube rack body from back to front.

[0008] Furthermore, the three-sided folding light shield includes a front shield, a top shield, and a rear shield. The front left and right sides of the rear shield are provided with protrusions, which are adapted to be embedded in the slide rail.

[0009] Furthermore, the upper groove has perforations on its front and rear sides, and the upper and lower parts of the front and rear sides of the liftable light-shielding side plate are correspondingly provided with retractable protrusions. The retractable protrusions are movably engaged with the perforations, and the liftable light-shielding side plate can move up and down and be fixed along the upper groove through the retractable protrusions.

[0010] Furthermore, the top of the liftable light-shielding side panel is provided with a semi-circular groove, and the bottom of the top shielding surface is provided with a semi-circular protrusion, which is movably embedded in the semi-circular groove.

[0011] Furthermore, the front cover has a handle on one side and a magnetic block at the bottom, and the front of the lower plate has an iron strip that is attracted to the magnetic block.

[0012] Furthermore, a limiting block is provided on the front side of the slide rail.

[0013] Furthermore, the side panel is provided with a carrying handle slot.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention firstly features an upward-facing upper groove on the side of the test tube rack, within which a height-adjustable light-shielding side panel is housed. During routine experiments, the height-adjustable light-shielding side panel is housed within the upper groove. Simultaneously, a rearward-facing groove is located at the bottom of the test tube rack, containing a three-sided folding light-shielding plate. During routine experiments, the three-sided folding light-shielding plate is housed within the rear groove, allowing the test tube rack to be used as a regular test tube rack. Next, when a light-shielding experiment is required, the height-adjustable light-shielding side panel is first pulled up and secured from the upper groove, and then the three-sided folding light-shielding plate is pulled out from the rear groove. The light-shielding panels are installed on the back, top, and front of the test tube rack. The adjustable side panels and three-sided folding light-shielding panels provide light protection for the test tube rack, facilitating light-avoidance experiments. The operation is convenient and effectively improves the success rate of experiments. Finally, after the experiment, the three-sided folding light-shielding panels are lifted and placed into the rear groove for storage, while the adjustable side panels are embedded in the upper groove. Switching is very convenient, and the entire design occupies little space, making it easy to carry and transport. This utility model has a novel structure, ingenious design, quick switching, and diverse functions, making it suitable for laboratory use and easy to promote. Attached Figure Description

A liftable light-shielding side plate 9 is built into the upper groove 8. The three-sided folding light-shielding plate 7 is pulled out backward and covers the back, top, and front of the test tube rack body 1 from back to front.

[0023] Furthermore, the three-sided folding light shield 7 includes a front shield 71, a top shield 72, and a rear shield 73. The rear shield 73 has protrusions 74 on the left and right sides of its front side, and the protrusions 74 are adapted to be embedded in the slide rail 6.

[0024] Furthermore, the upper groove 8 is provided with through holes 81 on the front and rear sides, and the upper and lower parts of the front and rear sides of the liftable light-shielding side plate 9 are provided with retractable protrusions 91. The retractable protrusions 91 are movably engaged with the through holes 81, and the liftable light-shielding side plate 9 can move up and down and be fixed along the upper groove 8 through the retractable protrusions 91.
