Description

Technical Field

[0001] This utility model relates to the field of microbial instrument technology, specifically to a transfer device for transferring culture flasks. Background Technology

[0002] Pass-through windows, as an auxiliary device in cleanrooms, are installed between clean areas (such as cleanrooms and sterile rooms) and non-clean areas (or between areas of different cleanliness levels). They are mainly used for transferring materials, culture bottles, and other items. Their primary design objective is to prevent contamination of the clean area from external sources during item transfer.

[0003] Traditionally, culture bottles are removed from the pass-through window one by one by operators, which is very inefficient. The pass-through window is open for a long time, which increases the chance of contamination. In addition, the manual operation process further increases the chance of contamination.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] Pass-through windows, as an auxiliary device in cleanrooms, are mainly used for transferring materials, culture flasks, and other items. The structure of a pass-through window is as follows: Figure 7 As shown, it includes a box 14, which is typically hollow inside and open on both sides. The lower surface of the inner wall of the box 14 is a support surface 15 for carrying culture bottles. When a transfer window is required, the culture bottles are placed on the support surface 15.

[0043] The pass-through window also includes a first support frame 16 and a second support frame 17 respectively disposed on opposite sides of the box 14, and a first side door and a second side door respectively disposed on the first support frame 16 and the second support frame 17 (the side doors are not shown in the figure, and only part of the structure of the pass-through window is shown in the figure). The first side door and the second side door are used to cover the openings on both sides of the box 14. When the pass-through window is in use, only the first side door or the second side door is opened.

[0044] The first support frame 16 and the second support frame 17 are used to support the first side door and the second side door respectively, and the first support frame 16 and the second support frame 17 respectively have an upward-facing support surface 18 for supporting the first side door or the second side door, and the height of the support surface 18 is lower than the height of the bearing surface 15.

[0045] One embodiment of this utility model provides a transfer device for transferring culture flasks. The transfer device includes a mobile trolley for docking with a transfer window to realize the transfer of culture flasks between the transfer window and the mobile trolley. Multiple culture flasks can be transferred between the transfer window and the mobile trolley at one time, greatly reducing human contact.

[0046] See Figure 1 As shown, the mobile trolley includes a frame 9 with wheels 10 at the bottom and a platform 11 on top of the frame 9 for carrying culture bottles. One end of the platform 11 extends outward to form an overlapping part 12. The upper surface of the overlapping part 12 is coplanar with the upper surface of the platform. When the mobile trolley docks with the transfer window, the overlapping part 12 overlaps the first support frame 16 or the second support frame 17, and the upper surface of the overlapping part 12 is flush with or lower than the bearing surface 15.

[0047] To facilitate the transfer of culture flasks between the transfer window and the moving trolley, that is, the culture flasks can be smoothly moved from the transfer window to the moving trolley and vice versa, when the moving trolley and the transfer window are connected, the upper surface of the overlapping part 12 is flush with the bearing surface 15.

[0048] In some alternative embodiments, the width of the overlapping portion 12 is greater than or equal to the width of the supporting surface 18, and the lower surface of the overlapping portion 12 is higher than the lower surface of the shelf 11, so that a step is formed between the end face of the overlapping portion 12 and the end face of the shelf 11, and when the moving trolley docks with the transfer window, the lower surface of the shelf 11 is lower than the supporting surface 18. Preferably, the width of the overlapping portion 12 is substantially equal to the width of the supporting surface 18, so that when the moving trolley docks with the transfer window, the overlapping portion 12 is exactly located on the supporting surface 18, and when docking, the end face of the shelf 11 abuts against the side of the transfer window.

[0049] In some alternative embodiments, there are multiple wheels 10, at least one of which is a brake wheel, so that the trolley remains relatively fixed when the culture flask moves between the trolley and the transfer window, facilitating operation. For example, there are four wheels 10, where two wheels 10 on the same side can be brake wheels, the four wheels can also be omnidirectional wheels, or two can be omnidirectional wheels and two can be directional wheels.

[0050] In some alternative embodiments, the frame 9 includes a base frame 9a and a plurality of uprights 9b vertically arranged on the base frame 9a. A storage platform 11 is arranged on the upper end of the plurality of uprights 9b, and four wheels 10 are respectively arranged at the four bottom corners of the base frame 9a. The frame 9 has a simple structure.

[0051] In some alternative embodiments, the mobile trolley also includes guardrails 13 disposed on opposite sides of the upper surface of the platform 11, with each guardrail 13 extending from one end of the platform 11 (the end connecting the overlapping part) to the other end of the platform 11.

[0052] The transfer device also includes a transfer tool for moving culture flasks from the transfer window onto a mobile cart.

[0053] Figure 3 This diagram shows a three-dimensional structural schematic of a delivery tool according to an embodiment of the present invention. Figure 4 A top view of the transfer tool is shown, which is used to remove culture flasks from the transfer window and move them onto a mobile cart.

[0054] As shown in the figure, the transfer tool includes a connecting plate 1, a first side plate 2, and a second side plate 3. The first side plate 2 has a first side plate connecting end and a first side plate handheld end, and the second side plate 3 has a second side plate connecting end and a second side plate handheld end. The first side plate connecting end is connected to one end of the connecting plate 1 via a first connecting strap 4, and the second side plate connecting end is connected to the other end of the connecting plate 1 via a second connecting strap 5. The first side plate 2 and the second side plate 3 are located on the same side of the connecting plate 1, so that the first side plate 2, the first connecting strap 4, the connecting plate 1, the second connecting strap 5, and the second side plate 3 together form a receiving space for accommodating culture bottles. The first side plate handheld end and the second side plate handheld end are separated from each other, so that the first side plate handheld end and the second side plate handheld end form an entrance and exit of the receiving space.

[0055] Both the first connecting strap 4 and the second connecting strap 5 are silicone connecting straps. Soft silicone connecting straps can be selected to facilitate the adjustment of the size of the accommodating space to a certain extent during use, so that the inner wall of the transfer tool can fit more tightly against the culture flask, making the picking and placing of the culture flask more stable, improving the use effect, and extending the service life.

[0056] Depend on Figure 3 and Figure 4 As can be seen, both the first connecting strip 4 and the second connecting strip 5 are arc-shaped, creating an arc-shaped transition between the connecting plate 1 and the first side plate 2, and between the connecting plate 1 and the second side plate 3. Furthermore, the first side plate 2 and the second side plate 3 are symmetrically arranged, resulting in better performance. The first connecting strip 4 is detachably connected to the first side plate 2 and the connecting plate 1 using screws and nuts, and the second connecting strip 5 is detachably connected to the second side plate 3 and the connecting plate 1 using screws and nuts, facilitating replacement. If the plates or connecting strips are damaged, only the damaged parts need to be replaced.

[0057] In an optional embodiment, the widths of the first side plate 2, the second side plate 3, and the connecting plate 1 are the same, and the widths of the first connecting strip 4 and the second connecting strip 5 are slightly smaller than the widths of the first side plate 2, the second side plate 3, or the connecting plate 1. For example, the width of the first side plate 2 (or the second side plate 3 or the connecting plate 1) is greater than 1 / 2 of the width of the first side plate 2 (or the second side plate 3 or the connecting plate 1).

[0058] The transfer tool also has a freely extendable initial state. In this initial state, the angles formed by the extension directions of the first side plate 2 and the connecting plate 1, and the angles formed by the extension directions of the second side plate 3 and the connecting plate 1, are both 90±5°. For example, in the initial state, the extension directions of the first side plate 2 and the connecting plate 1 are essentially perpendicular to each other, and the extension directions of the second side plate 3 and the connecting plate 1 are also essentially perpendicular to each other. Furthermore, the angles formed by the extension directions of the first side plate 2 and the connecting plate 1, and the angles formed by the extension directions of the second side plate 3 and the connecting plate 1, can be adjusted under external force. In actual operation, the size of the tool's accommodating space can be adaptively adjusted according to the shape and size of the culture flask being transferred, allowing the tool to better fit the culture flask and stably remove it from the transfer window.

[0059] The first side plate 2, the second side plate 3, and the connecting plate 1 are all made of metal sheets, such as aluminum alloy sheets. The opposite sides of the first side plate 2, the opposite sides of the second side plate 3, and the opposite sides of the connecting plate 1 are respectively provided with soft leather, which can protect the culture bottle and improve the safety of the operator.

[0060] To reduce the weight of the transfer tool while ensuring its strength, the first side plate 2, the second side plate 3, and the connecting plate 1 are all perforated materials. The outer surface of the first side plate 2 is provided with multiple first reinforcing ribs at intervals, each extending along the length of the first side plate 2. Both the upper and lower edges of the first side plate 2 have outwardly folded flanges. The outer surface of the second side plate 3 is provided with multiple second reinforcing ribs at intervals, each extending along the length of the second side plate 3. Both the upper and lower edges of the second side plate 3 have outwardly folded flanges. The outer surface of the connecting plate 1 is provided with multiple third reinforcing ribs 8 (e.g., ...). Figure 5 As shown), each of the third reinforcing ribs 8 extends along the length of the connecting plate 1, and the upper and lower edges of the connecting plate 1 are provided with outwardly folded flanges.

[0061] See also Figure 3 and Figure 6 The first side plate has a first through hole 6 penetrating the opposite sides of the first side plate 2 at the hand-hold end, and a first gripping part 2a for holding is formed between the end face of the first side plate hand-hold end and the first through hole 6; the second side plate has a second through hole 7 penetrating the opposite sides of the second side plate 3 at the hand-hold end, and a second gripping part 3a for holding is formed between the end face of the second side plate hand-hold end and the second through hole 7. Nylon is wound around both the first gripping part 2a and the second gripping part 3a for easy gripping.

[0062] During application, if it is necessary to remove the culture flask from the transfer window and transfer it to the mobile cart, such as... Figure 7As shown, the mobile trolley is first docked with the transfer window, with the trolley's overlapping part resting on the first support frame of the transfer window. Then, the culture flasks in the transfer window are inserted into the transfer tool. Pulling the transfer tool moves the culture flasks onto the mobile trolley in one go. This allows for the rapid removal and transfer of multiple culture flasks to the mobile trolley at once, significantly reducing the transfer window's opening time and effectively preventing contamination caused by prolonged opening. It also reduces human contact and improves work and production efficiency. Conversely, the culture flasks on the mobile trolley can be pushed into the transfer window all at once.

[0063] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
