Description

Technical Field

[0001] This utility model relates to the field of material placement technology, specifically to a material layering rack for the vaccine freeze-drying process. Background Technology

[0002] The core function of the material layering rack in the vaccine freeze-drying process is to ensure that each layer of vaccine vials can be uniformly frozen and sublimated, avoiding inconsistent freeze-drying effects due to differences in temperature and vacuum.

[0003] Traditional storage racks are mostly fixed shelves and welded frame structures. The shelf spacing is fixed before leaving the factory and cannot be adjusted according to the specifications of vaccine storage bottles. Its core drawback lies in its strong limitation on specifications. If the shelf spacing of traditional racks is designed for small-capacity vials, when large-capacity storage bottles need to be freeze-dried, the height of the bottles exceeds the shelf spacing, which will cause the shelves to squeeze the bottles or prevent them from being placed. If designed for large-capacity bottles, the gaps between the shelves will be too large when storing small-capacity bottles, which will waste space in the freeze-drying chamber, reduce the batch size of freeze-drying, and increase production costs. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material layering rack for the freeze-drying process of vaccines, comprising a rack body, two side vertical grooves on both sides of the rack body, and multiple height-adjustable racks arranged inside the rack body, with two movable rods at both ends of each height-adjustable rack, the movable rods being located in the side vertical grooves to guide and limit the movement of the movable rods;

[0006] The movable rod is movably fitted with a movable sleeve, and an insert is fixedly installed on the movable sleeve. The insert is movably inserted into rectangular slots opened on both sides of the frame body.

[0007] Preferably, multiple rectangular slots are equally spaced on both sides of the frame body.

[0008] Preferably, the insert and the rectangular slot are adapted to each other in shape.

[0009] Preferably, protective baffles are fixedly installed on both sides of the frame body, and the protective baffles are used to protect the movable rods.

[0010] Preferably, the extended end of the movable rod is located between the protective baffles, and the extended end of the movable rod is located within the recessed structure formed by the frame body and the two protective baffles.

[0011] Preferably, locking plates are bolted to both the front and back of the frame body, and a back plate is mounted on the frame body via the installed locking plates.

[0012] Preferably, the back panel is located on the front and back of the height-adjustable frame, and the width of the structure formed by the back panel and the height-adjustable frame is the same as the width of the frame body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The placement rack utilizes a combination of movable rods, side vertical grooves, inserts, and rectangular slots to achieve free adjustment and stable fixation of the height-adjustable rack. Adjustment is simple: just push the height-adjustable rack, slide the movable rod along the side vertical groove to the target height, and then use the movable sleeve to insert the insert into the corresponding rectangular slot to complete the fixation. No additional tools are required. The equidistant distribution of the rectangular slots ensures adjustment accuracy. Whether the freeze-dried vaccine uses small-capacity vials or large-capacity storage bottles, the spacing between layers can be adjusted to ensure sufficient airflow space above each layer of bottles, avoiding interference between layers or poor airflow due to differences in bottle height. This adaptability covers the vast majority of vaccine freeze-drying scenarios. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a material layering rack for the freeze-drying process of vaccines. The rack body 1 is a frame structure. Two parallel side vertical grooves 2 are integrally formed on both sides of the frame. Multiple rectangular slots 101 are equally spaced along the vertical direction on the inner side walls of both sides of the frame. The number of rectangular slots 101 is set according to the actual layering requirements. Protective baffles 7 are fixedly installed on the outer side walls of both sides of the frame body 1 by welding. The two protective baffles 7 are symmetrically distributed and together with the side frames of the rack body 1 form a U-shaped recessed structure to protect and block the protruding end of the subsequent movable rod 4.

[0022] The height-adjustable frame 3 is a rectangular metal frame, and its number is set according to the actual layering requirements. Two movable rods 4 are fixedly connected to both ends of the height-adjustable frame 3 by welding. The two movable rods 4 correspond one-to-one with the side vertical grooves 2 on both sides of the frame body 1. The outer diameter of the movable rod 4 is adapted to the groove width of the side vertical groove 2. The end of the movable rod 4 away from the height-adjustable frame 3 passes through the side vertical groove 2 and extends into the recessed structure formed by the side frame of the frame body 1 and the protective baffle 7, so as to realize the sliding guidance and limit of the movable rod 4 in the side vertical groove 2.

[0023] A movable sleeve 5 is movably fitted on the outer wall of the movable rod 4. The inner diameter of the movable sleeve 5 is clearance-fitted with the outer diameter of the movable rod 4 to ensure that the movable sleeve 5 can slide along the axial direction of the movable rod 4. An insert 6 is fixedly installed on the outer wall of the movable sleeve 5 by welding. The shape of the insert 6 is perfectly adapted to the rectangular slot 101 on the side frame of the frame body 1, and the length of the insert 6 is slightly less than the depth of the rectangular slot 101 to ensure that the insert 6 can be fully inserted into the rectangular slot 101 for fixation.

[0024] Connection between locking plate and back plate

[0025] Bolt holes are pre-drilled at the corners of the front and back of the frame body 1. The locking plate 8 is an L-shaped metal plate with mounting holes at both ends that match the bolt holes of the frame body 1. The locking plate 8 is fixedly installed at the corners of the front and back of the frame body 1 by bolts passing through the mounting holes and the bolt holes of the frame body 1. The back plate 9 is a rectangular metal plate (material consistent with the height-adjustable frame 3). Its width is the same as the width of the frame body 1, and its height matches the height of the frame body 1. The back plate 9 is attached to the front or back of the height-adjustable frame 3 by snap-fit, and the edge of the back plate 9 is tightly attached to the inner wall of the locking plate 8. The locking plate 8 limits and fixes the back plate 9 to ensure that the width of the structure formed by the back plate 9 and the height-adjustable frame 3 is consistent with the width of the frame body 1.

[0026] Working principle:

[0027] Depending on the requirements of vaccine freeze-drying, the back plate 9 may or may not be installed on one side of the shelf body 1. When installing the back plate 9, it is snapped into one side of the height-adjustable frame 3 and located inside the shelf body 1. Then, the locking plate 8 is fixed to the corner of the shelf body 1 with bolts, thus realizing the installation of the back plate 9 and fixing it through the locking plate 8. Then, according to the height of the freeze-dried vaccine storage bottle, the installation position of the height-adjustable frame 3 on the shelf body 1 is adjusted. The movable rod 4 slides in the side vertical groove 2. After the height-adjustable frame 3 is adjusted to a suitable height, the movable sleeve 5 on the movable rod 4 is moved. The movable sleeve 5 pushes the insert 6 to move. The insert 6 moves and inserts into the rectangular slot 101, thus realizing the fixation of the height-adjustable frame 3 after movement. After the height-adjustable frame 3 is fixed, the vaccine storage bottles are placed on the height-adjustable frame 3 to realize the layered placement of vaccines.
