Abstract
Description
Technical Field
[0001] This utility model relates to the field of test tube rack technology, specifically a multifunctional test tube rack for use in a laboratory. Background Technology
[0002] In hospital laboratories, test tube racks are a standard laboratory component, playing a crucial role in stabilizing and protecting samples within the test tubes. Traditional test tube racks are typically made of metal to ensure sufficient structural strength and durability. These racks usually include a flat base to support the test tubes containing the samples.
[0003] However, the test tube rack design in this technology has several significant drawbacks. First, due to the lack of an anti-detachment device at the top, test tubes are prone to falling out of the rack during transportation, especially when moving the rack or responding to emergencies within the hospital. Furthermore, if a test tube accidentally falls or breaks, samples may leak onto the rack or even the work surface, increasing the workload of cleaning and sterilization, and potentially leading to cross-contamination of samples, affecting the accuracy and reliability of experimental results.
[0004] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Utility Model Content
[0005] This application provides a multifunctional test tube rack for laboratory use, which solves the problem in related technologies where the test tube rack does not have an anti-detachment device at the top, making it easy for test tubes to fall off the rack during transportation.
[0006] To achieve the above objectives, this application adopts the following technical solution: a multifunctional test tube rack for laboratory use, comprising a base, test tube trays, a covering assembly, and a handle. The base is provided with at least two layers of test tube trays. The covering assembly includes a cover plate and a connecting plate. The cover plate is connected to one end of the connecting plate, and the other end of the connecting plate is rotatably connected to one end of the base, so that the cover plate can switch back and forth between a first position and a second position. In the second position, the cover plate is located directly above the test tube trays and completely covers the test tube trays. The cover plate abuts against the test tubes or has a slight gap. A handle is provided on the surface of the cover plate away from the test tube trays. A magnet may be provided inside the handle, and the magnetic attraction can be used to lock the cover assembly stably in the second position.
[0007] In this embodiment, the covering component switches back and forth between a first position (open) and a second position (closed). When the covering component is in the second position, the cover completely covers the test tube tray, and the friction between the cover and the test tubes prevents the test tubes from shaking or falling off during movement. When the covering component is in the first position, the test tube rack can hold the test tubes normally, and the cover component can be placed on the operating table.
[0008] In addition, the handle design facilitates carrying and moving the test tube rack. Furthermore, when the user holds the handle, the gripping force can be used to keep the cap assembly stably in the second position. In summary, the multifunctional test tube rack for laboratory use provided in this application embodiment can effectively prevent test tubes from falling off during transportation, effectively avoid sample leakage caused by test tube breakage, thereby avoiding cross-contamination and reducing the workload of cleaning and disinfection.
[0009] In some possible implementations, two sets of covering components are arranged symmetrically. This allows the cover plate to fit snugly when the covering components are in the second position, increasing the overall structural stability.
[0010] In some possible implementations, in the second position, a first friction pad is provided on the surface of the cover plate facing the test tube tray. This increases the friction between the cover plate and the test tubes, further preventing the test tubes from shifting during transportation.
[0011] In some possible implementations, the connecting plate is rotatably connected to the base via a damping shaft or a regular shaft. This allows the cover to open and close more smoothly, improving safety and ease of operation during use.
[0012] In some possible implementations, a second friction pad is provided on the surface of the base facing the test tube tray. This increases the friction between the test tube and the base, making the test tube more stable on the base.
[0013] In some possible implementations, the second friction pad has multiple positioning holes, which correspond one-to-one with the multiple placement holes on the test tube tray. This ensures, on the one hand, that the test tubes are accurately positioned during placement, preventing them from tilting or moving; on the other hand, it increases the contact area between the friction pad and the test tubes, further increasing the friction between the test tubes and the base, making the test tubes more stable on the base.
[0014] In some possible implementations, the second friction pad is a rubber pad. Because the rubber pad material has both a high coefficient of friction and elasticity, it can better adapt to the shape of the test tube, allowing the bottom of the test tube to be better covered, thus effectively preventing the test tube from sliding and absorbing vibration.
[0015] The advantages of this invention are: the fully enclosed protective test tube rack provides comprehensive protection for the test tubes, and the rubber pads provide cushioning to prevent damage from collisions. Attached Figure Description

[0027] Please see Figure 1 and combined Figure 2 This application discloses a multifunctional test tube rack for laboratory use, including a base (1), a test tube tray (2), a cover assembly (3), a side panel (4), and a handle (5). At least two layers of test tube trays (2) are provided on the base (1). Specifically, a column (11) is provided at each of the four corners of the base (1), and the test tube trays (2) are fixedly mounted on the column (11).
[0028] The covering assembly (3) includes a cover plate (31) and a first connecting plate (32). The cover plate (31) is connected to one end of the connecting plate (32). Specifically, the cover plate (31) and the connecting plate (32) can be fixedly connected by means of screw connection, snap-fit, welding, etc.; or the cover plate (31) and the connecting plate (32) are integrally formed parts. The other end of the connecting plate (32) is rotatably connected to one end of the base (1) so that the cover plate (31) can switch back and forth between the first position and the second position. In the second position, the cover plate (31) is located directly above the test tube tray (2), and two sets of covering components are arranged opposite each other and completely cover the test tube tray (2). The cover plate (31) abuts against the test tube (8). In the second position, the cover plate (31) is provided with a handle (5) away from the surface of the test tube tray (2). A magnet may be provided in the handle, and the handle may be locked by the attraction of the magnet to prevent it from being loosened. For example, the handle (5) and the cover plate (31) may be fixedly connected by screw connection, snap-fit, welding or other means; or the handle (5) and the cover plate (31) may be integrally formed.
[0029] In this way, the cover assembly (3) can switch back and forth between a first position (open) and a second position (closed). When the cover assembly (3) is in the second position, the cover completely covers the test tube tray (2), and the friction between the cover (31) and the test tube (8) prevents the test tube (8) from shaking or falling off during movement. When the cover assembly (3) is in the first position, the test tube rack can hold the test tube (8) normally, and the cover assembly (31) can be placed on the operating table.
[0030] Furthermore, the handle (5) design facilitates carrying and moving the test tube rack. Additionally, a magnet is hidden within the handle (5), allowing the capping assembly (3) to be stably held in the second position using magnetic attraction. In summary, the multifunctional test tube rack for laboratory use provided in this application embodiment effectively prevents test tubes (8) from falling off during transport, effectively avoiding sample leakage caused by test tube (8) breakage, thereby preventing cross-contamination and reducing the workload of cleaning and disinfection.
[0031] Please see Figure 1 In some embodiments, two sets of covering components 3 are symmetrically arranged. In this way, when the covering components 3 are in the second position, the cover plate (31) can fit tightly, increasing the stability of the overall structure.
[0032] Please see Figure 1 In some embodiments, in the second position, a first friction pad (6) is provided on the surface of the cover plate (31) facing the test tube tray (2). For example, the first friction pad (6) and the cover plate (31) can be fixedly connected by means of screws, adhesives, etc. In this way, the friction between the cover plate and the test tube (8) can be increased, further preventing the test tube (8) from shifting during transportation.
[0033] In some embodiments, the connecting plate (32) is rotatably connected to the base (1) via a damping shaft. This makes the cover plate (31) more stable during opening and closing, improving safety and ease of operation. Of course, this application is not limited to this. In other embodiments, the connecting plate is rotatably connected to the base via a common rotating shaft and a shaft hole. Specifically, one end of the rotating shaft is fixedly connected to the connecting plate, and a shaft hole is provided on the base. The shaft hole can be a through hole or a blind hole.
[0034] Please see Figure 2 In some embodiments, a second friction pad (7) is provided on the surface of the base (1) facing the test tube tray (2). The second friction pad and the base can be fixedly connected by means of screw connection, snap-fit, adhesive or other means, which can increase the friction between the test tube (8) and the base (1) and make the test tube more stable on the base.
[0035] Please see Figure 3 In some embodiments, the second friction pad (7) is provided with multiple positioning holes (71), which correspond to multiple placement holes on the test tube tray. In this way, on the one hand, it can ensure that the test tube (8) can be accurately positioned when placed, preventing the test tube from tilting or moving; on the other hand, it can increase the contact area between the friction pad and the test tube, further increasing the friction between the test tube and the base, making the test tube more stable on the base.
[0036] In some embodiments, the second friction pad (7) is a rubber pad. Since the rubber pad material has both a high coefficient of friction and elasticity, it can better adapt to the shape of the test tube (8), so that the bottom of the test tube can be better wrapped, thereby effectively preventing the test tube 8 from sliding and absorbing vibration.
[0037] like Figure 4 , 5 As shown, baffles are installed on the side of the test tube rack. The baffles are made of soft material and are fixedly installed on the test tube rack to enhance the protection of the test tubes. Fixed baffles are installed at the front and back of the test tube rack or the connecting plate (32) is widened directly to make the entire test tube rack fully enclosed for protection.
[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
