Description

Technical Field

[0001] The utility model belongs to the technical field of cell cold storage racks, in particular to a cell freezing rack with an adjustment function. Background Art

[0002] Stem cell cryopreservation technology, as the core method of stem cell preservation, temporarily stops the growth of cells by placing them in an extremely low temperature environment (-196°C), thereby effectively preserving their unique cell characteristics. In the process of cell cryopreservation, cold storage racks play a vital role.

[0003] However, the cold storage rack design in the prior art, as described in the Chinese utility model patent document described in announcement number CN204355609U, has obvious limitations. Since the horizontal and vertical partitions are fixed and have no adjustment function, the size of the cells formed is fixed and the spacing between the cells cannot be flexibly adjusted to meet the storage needs of cold storage boxes of different sizes. In addition, the rotating locking block used in this design can only limit the cold storage boxes in four cells, and each operation requires twisting the locking block to individually remove the cold storage boxes in each cell, which greatly reduces the convenience and efficiency of the operation, and cannot achieve a one-time simple operation to remove the cold storage boxes in multiple cells.

[0004] Therefore, it is very necessary to invent a cell freezing rack with regulating function. Utility Model Content

The partition body is engaged and fixedly connected with a locking hole provided in the cold storage frame through the locking bolt. The locking bolt is movably mounted on the partition body and is limited by the limit plate. The limit plate is fixedly mounted on the locking bolt.

[0007] The freezing box locking shaft is composed of a pin shaft, a pin head and a thread, and the thread of the freezing box locking shaft is engaged and fixedly installed on the screw hole provided on the cold storage frame.

[0008] Preferably, the cold storage frame includes a frame, a baffle, a pull ring and a transverse plate, the label box and the baffle are fixedly installed on the outer surface of the frame; at least one transverse plate is fixedly installed on the inner side of the frame, and the baffle is fixedly connected to the transverse plate and the frame; the partition body is fixedly connected to the locking hole opened in the transverse plate by engaging with the locking bolt.

[0009] Preferably, the inner surface of the frame is provided with a screw hole which is engaged with the thread of the freezing box locking shaft for fixed installation, and the frame is also provided with a countersunk hole which allows the pin shaft of the freezing box locking shaft to pass through but does not allow the pin head of the freezing box locking shaft to pass through.

[0010] Preferably, at least two freezing box locking shafts are provided, and the pin shafts of the freezing box locking shafts slide through the sliding holes provided on the partition body, and the sliding holes are located on both sides of the slot.

[0011] Preferably, the partition body is a "T"-shaped structure, the size of the slot provided on the partition body corresponds to the transverse plate, and the slot is located on one side of the locking bolt.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model has made revolutionary innovations in the design of cold storage racks, abandoning the limitations of the fixed setting of horizontal and vertical partitions in traditional technologies. The flexible adjustment of the size of the cells is achieved by introducing spacing partitions. The spacing partitions have a clever structural design, and the spacing between cells can be adjusted as needed, so that the cold storage rack can adapt to the storage needs of cold storage boxes of different sizes.

[0021] As attached Figure 1 To Attachment Figure 3 As shown:

[0022] The utility model provides a cell freezing rack with an adjustment function, comprising a cold storage frame 1, a spacing partition 2, a label plug-in box 3 and a freezing box locking shaft 4, wherein at least one of the spacing partitions 2 is fixedly installed inside the cold storage frame 1, and the label plug-in box 3 is fixedly installed on the outer surface of the cold storage frame 1; the freezing box locking shaft 4 slides through the spacing partition 2 and is fixedly connected to the cold storage frame 1.

[0023] The spacing partition 2 includes a partition body 21, a slot 22, a locking bolt 23 and a limiting plate 24. The slot 22 is provided in the middle of the partition body 21. The partition body 21 is engaged and fixedly connected with the locking hole 15 provided on the cold storage frame 1 through the locking bolt 23. The locking bolt 23 is movably mounted on the partition body 21 and is limited by the limiting plate 24. The limiting plate 24 is fixedly mounted on the locking bolt 23. The spacing partition 2 realizes flexible adjustment of the size of the cell. This spacing partition has an ingenious structural design, and the spacing between the cells can be adjusted as needed, so that the cold storage rack can adapt to the storage needs of cold storage boxes of different sizes.

[0024] The freezing box locking shaft 4 is composed of a pin shaft, a pin head and a thread. The thread of the freezing box locking shaft 4 is engaged and fixedly installed on the screw hole set in the cold storage frame 1. The thread is set at one end of the pin shaft. The freezing box locking shaft 4 can restrict or release the restrictions on the cold storage boxes in four or more cells at one time, which greatly simplifies the operation process.

[0025] Embodiment 1:

[0026] Specifically, the cold storage frame 1 includes a frame 11, a baffle 12, a pull ring 13 and a transverse plate 14, the label box 3 and the baffle 12 are fixedly installed on the outer surface of the frame 11; at least one transverse plate 14 is fixedly installed on the inner side of the frame 11, and the baffle 12 is fixedly connected to the transverse plate 14 and the frame 11; the partition body 21 is engaged and fixedly connected with the locking hole 15 opened in the transverse plate 14 through the locking bolt 23, and the transverse plate 14 is evenly distributed with a plurality of locking holes 15. The number of transverse plates 14 and partition body 21 installed depends on the needs of the user. The rectangular spacing between the transverse plate 14 and the partition body 21 bracket is the cell where the cold storage box is placed. The cold storage box in the cell will be blocked by the baffle 12 or the partition body 21 to prevent it from falling out from the direction without the freezing box locking shaft 4.

[0027] Specifically, the inner surface of the frame 11 is carefully provided with screw holes matching the threads of the freezer box locking shaft 4, ensuring that the freezer box locking shaft 4 can be stably and firmly mounted on the frame 11 through threaded engagement. In addition, the frame 11 is also cleverly provided with countersunk holes, which allow the pin of the freezer box locking shaft 4 to pass through easily, but cleverly restrict the passage of the pin head, thereby ensuring the stability and safety of the locking shaft.

[0028] Specifically, at least two freezing box locking shafts 4 are provided, and the pin shaft of the freezing box locking shaft 4 slides through the sliding hole opened on the partition body 21, and the sliding hole is located on both sides of the card slot 22. By passing the pin shaft through the sliding hole, the freezing box locking shaft 4 can be easily aligned and locked or unlocked the cold storage box, thereby realizing a one-time operation of the cold storage boxes in multiple cells.

[0029] Specifically, the partition body 21 is a "T"-shaped structure. The size of the slot 22 on the partition body 21 corresponds to the horizontal plate 14. The slot 22 is located on one side of the locking bolt 23. Due to the restriction of the limit plate 24, the locking bolt 23 will not be separated from the partition body 21, thereby avoiding the loss of the locking bolt 23.

[0030] Embodiment 2:

[0031] Spacing adjustment: By adjusting the locking bolts 23 installed on the partition body 21 to engage with the locking holes 15 at different positions on the transverse plate 14 of the cold storage frame 1, the position of the partition body 21 in the cold storage frame 1 can be changed, thereby adjusting the spacing between different cells. This design allows the user to flexibly adjust the size of the cell according to the actual size of the cold storage box to meet the storage requirements of cold storage boxes of different sizes.

[0032] Freezer box locking: The pin of the freezer box locking shaft 4 slides through the sliding hole on the partition body 21, and is engaged and fixed with the screw hole of the cold storage frame 1 through its thread, thereby locking the cold storage box; when the cold storage box needs to be unlocked, the freezer box locking shaft 4 is rotated in the opposite direction so that its thread no longer engages with the screw hole of the cold storage frame 1, and the freezer box locking shaft 4 is pulled out, so that the cold storage box can be easily taken out.

[0033] Embodiment three:

[0034] Workflow:

[0035] Preparation stage: According to the size of the cold storage box, select the appropriate number of transverse plates 14 and partition bodies 21, fix them to each other through locking bolts 23, and install them in the frame 11 of the cold storage frame 1 to form cells of different sizes.

[0036] Place the cold storage box: Place the cold storage box into the adjusted cell, ensure that the cold storage box matches the cell size and is blocked by the blocking plate 12 or the partition body 21 to prevent it from falling out from the direction without the freezing box locking shaft 4.

[0037] Locking the cold storage box: Rotate the freezing box locking shaft 4 so that its thread engages with the screw hole of the cold storage frame 1 and is fixed, and the cold storage box is restricted and fixed in the cell by the pin shaft. The cold storage boxes in four or more cells can be locked at one time.

[0038] Unlocking and removing the cold storage box: When the cold storage box needs to be removed, the freezing box locking shaft 4 is rotated in the opposite direction so that its thread is no longer engaged with the screw hole of the cold storage frame 1, and the freezing box locking shaft 4 is pulled out, and then the cold storage box can be easily removed. Similarly, the cold storage boxes in four or more cells can be unlocked at one time.

[0039] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
