Detailed Implementation

[0029] Example 1: As Figures 1-8 As shown, this embodiment provides a cell culture bag placement rack, including a vertical frame 11, a rotating shaft 12 rotatably mounted on the vertical frame 11, and a folding mechanism 2 mounted on the rotating shaft 12;

[0030] The folding mechanism 2 includes: a flip plate 21, which is mounted on the rotating shaft 12; a folding assembly 22, which is mounted below the flip plate 21; a locking assembly 23, which is disposed on the folding assembly 22; and a limiting assembly 24, which is mounted on the vertical frame 11.

[0031] The folding assembly 22 includes: a first link 221; a second link 222, which is rotatably connected to the first link 221; and a support plate 223, which is rotatably disposed at the bottom of the second link 222.

[0032] The locking assembly 23 includes: a through hole 220, which is formed on the support plate 223; a first threaded hole 210, which is formed on the flip plate 21; and a first bolt 231, which passes through the through hole 220 and is threadedly connected to the first threaded hole 210.

[0033] The limiting component 24 includes: a slot 121, which is formed at one end of the rotating shaft 12; a mounting sleeve 241, which is mounted on one side of the vertical frame 11 and has a circular groove 2411 inside; a round rod 242, which is slidably disposed on the circular groove 2411; and a locking block 243, which is mounted at one end of the round rod 242.

[0034] The mounting sleeve 241 has a groove 2412 inside, and a protrusion 244 is installed on the round rod 242. The protrusion 244 slides in the groove 2412; a pull ring 245 is installed on the round rod 242.

[0035] In this embodiment, the initial state is as follows: Figure 1 As shown, the top of the flip plate 21 and the top of the support plate 223 are used to place cell culture bags. Multiple support plates 223 can hold more cell culture bags, which facilitates the use of the device.

[0036] When the rack is no longer in use, remove the cell culture bags, move the support plate 223 upwards, and rotate and fold the first connecting rod 221 and the second connecting rod 222 so that the multiple support plates 223 are pressed together. At this time, the first bolt 231 passes through the through hole 220 and is threaded into the first threaded hole 210, fixing the multiple support plates 223 to the bottom of the flip plate 21 (as shown in the image). Figure 2 (as shown)

[0037] Pulling out the pull ring 245 drives the card block 243 to leave the card slot 121. At this time, the flip plate 21 can be rotated to make it face downward, completing the folding and storage of the shelf. When not in use, the shelf can be folded and stored, taking up less space in the room and making good use of the room space.

[0038] Example 2: Figures 1-8 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0039] like Figures 1-8 As shown, in this embodiment, the vertical frame 11 is provided with an adsorption mechanism 3. The adsorption mechanism 3 is adsorbed onto the wall surface by negative pressure. The adsorption mechanism 3 includes: an adsorption ring 30, which is disposed on one side of the vertical frame 11; a compression chamber 122, which is opened in the rotating shaft 12; a piston 31, which is slidably disposed in the compression chamber 122; a screw 32, which is threadedly connected to the rotating shaft 12 and is rotatably connected to the piston 31; and a drive assembly 33, which is installed at the other end of the rotating shaft 12.

[0040] The drive assembly 33 includes: a rotating rod 331, which is rotatably disposed within the rotating shaft 12; a fixed sleeve 332, which is mounted on the rotating rod 331 and has a hexagonal groove 3321 inside; and a screw 32, which has a concave hole 321 inside; and a convex strip 333, which is mounted on the rotating rod 331 and slides within the concave hole 321.

[0041] In this embodiment, when installing the placement rack, the vertical frame 11 is attached to the wall so that the adsorption ring 30 contacts the wall. At this time, a wrench is used to rotate the fixing sleeve 332 to drive the rotating rod 331 to rotate, which in turn drives the screw 32 to rotate. According to the principle of thread transmission, the piston 31 is driven to move in the compression chamber 122, which is then drawn into the compression chamber 122 to a negative pressure. The negative pressure is transmitted through the pipe to the gap between the adsorption ring 30 and the wall. The negative pressure adsorbs and attaches the vertical frame 11 to the wall, thus completing the installation of the placement rack. The installation is simple, does not require drilling holes in the wall, and allows the placement rack to be installed in any (suitable) position on the wall, making it highly practical.

[0042] Working principle:

[0043] Folding and storage: Initial state as follows Figure 1As shown, the top of the turnover plate 21 and the top of the bearing plate 223 are used to place the cell culture bag, and multiple bearing plates 223 can be placed to place more cell culture bags. When the rack is no longer used, the upper cell culture bag is removed, the bearing plate 223 is moved upward, the first connecting rod 221 and the second connecting rod 222 are rotated and folded, and multiple bearing plates 223 are attached together. At this time, the first bolt 231 is screwed through the through hole 220 and the first threaded hole 210 to fix the multiple bearing plates 223 at the bottom of the turnover plate 21 (state as shown in Figure 2

[0044] Pull out the pull ring 245 to drive the clamping block 243 away from the clamping groove 121. At this time, the turnover plate 21 can be rotated downward to complete the folding and storage of the rack. When not in use, the rack is folded and stored, occupying less space in the room, which is beneficial to the utilization of the room space.

[0045] Convenient installation: when installing the rack, the vertical frame 11 is attached to the wall surface, and the suction ring 30 is in contact with the wall surface. At this time, the wrench is used to rotate the fixed sleeve 332 to drive the rotating rod 331 to rotate, and the screw rod 32 is driven to rotate. According to the screw transmission principle, the piston 31 moves in the compression cavity 122, and the compression cavity 122 is extracted to negative pressure. The negative pressure is transmitted to the gap between the suction ring 30 and the wall surface through the pipeline, and the vertical frame 11 is attached to the wall surface through the negative pressure. The installation of the rack is completed, and the installation is simple and does not need to open a hole in the wall.

[0046] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.​
