Technical Field
[0001] The utility model relates to the technical field of stages, in particular to an adjustable stage for vacuum freeze-drying. Background Technique
[0002] A freeze-drying device, also known as a freeze dryer, is a device used to remove moisture from substances, mainly used in fields such as pharmaceuticals, biotechnology, food, and chemical industries. Its basic working principle is to first freeze the substance and then remove the moisture through sublimation in a vacuum environment. It mainly consists of a refrigeration system, a vacuum system, a heating system, and a stage.
[0003] The stage is an important component of the freeze-drying device, used to support and position the samples to be processed during the freeze-drying process. The stage is generally made of corrosion-resistant and low-temperature-resistant materials, such as stainless steel or special alloys, to ensure its stability and durability in a vacuum and low-temperature environment.
[0004] Currently, the existing stages for vacuum freeze-drying are provided with multiple connecting rods, and multiple loading trays are sleeved on the connecting rods. Nuts are installed on the loading trays and are threadedly connected to the connecting rods. By rotating the nuts, the height of the corresponding layer of loading trays can be adjusted. However, when adjusting the height, it will cause the upper space to expand or contract, unable to save space, and the reduced upper space cannot be used. Multiple adjustments are required. At the same time, it is not convenient to quickly disassemble the required loading trays. It is necessary to remove the upper loading trays one by one until the required loading tray is removed, and then reinstall the upper removed loading trays, resulting in a cumbersome and complex use problem. Content of the Utility Model
[0005] (I) Technical Problems to be Solved
[0006] In view of the deficiencies of the prior art, the utility model provides an adjustable stage for vacuum freeze-drying, which has the advantages of being able to adjust the height of the corresponding layer of loading trays without affecting the height of other layers, and at the same time being convenient for quickly disassembling and assembling the required loading trays, solving the problems that the upper space cannot be used when adjusting the height of the current loading trays and it is not convenient to disassemble and assemble the corresponding layer of loading trays.
[0007] (II) Technical Solutions
[0008] To achieve the above object, the present utility model provides the following technical solution: An adjustable loading platform for vacuum freeze-drying, comprising a tabletop assembly and a support assembly. The tabletop assembly includes a plurality of loading trays. Docking buttons are provided on the plurality of loading trays, and screw buttons are fixed on the docking buttons. The plurality of loading trays are designed in a stacked manner, which can provide a multi-layer placement space for the objects to be dried, utilize the space, and save the occupied space.
[0009] The support assembly includes support rods installed between the plurality of loading trays. A stabilizing hole is provided in the support rod, and an extension rod is threadedly connected in the stabilizing hole. A control knob is fixed at one end of the extension rod, and a connection button is movably hinged at one end of the control knob. A screw hole is provided in the connection button, and the screw hole is threadedly connected to the screw button. The support rod realizes the setting of the spacing between the multi-layer loading trays. At the same time, by rotating the extension rod, the extension rod can be telescopically moved to adjust the distance between two adjacent loading trays, so as to meet the storage of larger and smaller items. When loading larger items, the extension rod extends out to expand the spacing height between adjacent loading trays. When loading smaller items, the extension rod retracts to reduce the distance height between adjacent loading trays, saving the use space.
[0010] When assembling and using the adjustable loading platform for vacuum freeze-drying, by providing a plurality of loading trays, stacking the loading trays, and installing a support assembly between adjacent loading trays. The connection button at the top of the support rod is threadedly connected to the screw button provided at the bottom of the upper loading tray through the screw hole provided, and the connection button at the bottom of the support rod is threadedly connected to the screw button provided on the top surface of the lower loading tray through the screw hole provided, so as to realize the equidistant installation between the plurality of loading trays. After the installation is completed, adjust the distance between adjacent loading trays according to the size of the items to be vacuum freeze-dried. By rotating the control knob clockwise, the extension rod extends out under the action of the threaded connection between the side thread of the extension rod and the internal thread of the stabilizing hole, realizing the expansion of the spacing between adjacent loading trays. Place the larger items to be dried on the bottom loading tray of the two adjacent loading trays. By rotating the control knob counterclockwise, the extension rod is retracted into the support rod under the action of the threaded connection between the side thread of the extension rod and the internal thread of the stabilizing hole, reducing the distance between adjacent loading trays. Then place the smaller items on the bottom loading tray of the two adjacent loading trays. When placing the items, by rotating the limit sliding button, the limit sliding button is closely attached to the side of the limit rib to fix the length position of the extension rod.
[0011] As a further improvement of the above solution, through holes are provided on the loading tray.
[0012] Through the above technical solution, through holes are provided on multiple loading trays to achieve the effect of ventilation, ensuring that the side of the drying object placed above close to the loading tray can maintain good ventilation, and ensuring the dryness of the object.
[0013] As a further improvement of the above solution, among the multiple loading trays, partition buttons are provided on the topmost and bottommost loading trays.
[0014] Through the above technical solution, the partition buttons play a role in restricting installation and at the same time avoid having an anti-slip layer, so that when the bottom partition button fits on the tabletop, the frictional resistance between it and the contact surface is increased, avoiding the phenomenon that the loading platform slides and causes tipping.
[0015] As a further improvement of the above solution, among the multiple loading trays, a hinge button is provided on the topmost loading tray, and a handle is movably hinged on the hinge button.
[0016] Through the above technical solution, by pulling the handle, the whole device can be lifted, so as to facilitate moving it to the required position. When it is not necessary to move, the handle can be tilted and folded to either side, saving the top space.
[0017] As a further improvement of the above solution, a limiting chute is provided on the side of the support rod, the limiting chute penetrates through the stabilizing hole, and at the same time, one end of the extension rod is movably hinged with a stabilizing button, and a limiting slide button is threadedly connected to the side of the stabilizing button, and the limiting slide button is slidably connected in the limiting chute.
[0018] Through the above technical solution, when the extension rod rotates, under the action of the threaded connection in the stabilizing hole, the extension rod gradually extends, and at the same time drives the stabilizing button to slide in the stabilizing hole. At this time, the limiting slide button slides in the limiting chute, avoiding the effect that the extension rod drives the stabilizing button to rotate at the same time, and improving the stability of the telescopic movement of the extension rod.
[0019] As a further improvement of the above solution, limiting ridges are provided in the limiting chute, and the limiting slide button fits against the side of the limiting ridge.
[0020] Through the above technical solution, when the extension rod moves outwards to an appropriate length, the limiting slide button stays at the corresponding position in the limiting chute. At this time, by rotating the limiting slide button, the limiting slide button is pressed against the side of the limiting ridge, so as to fix the position adjusted by the extension rod, avoiding the effect of the free telescopic movement of the extension rod. By rotating the limiting slide button clockwise, the position of the extension rod is fixed, and by rotating the limiting slide button counterclockwise, the extension rod can freely telescopic and move.
[0021] Compared with the prior art, the present utility model provides an adjustable loading platform for vacuum freeze-drying, which has the following beneficial effects:
[0022] 1. The adjustable carrier table for vacuum freeze-drying ensures a certain distance between multiple carrier trays by installing support components between each layer of carrier trays. By rotating the control knob on the corresponding layer clockwise or counterclockwise, the extension rod can telescopically move within the support rod, achieving the expansion or contraction of the distance and height between adjacent carrier trays without affecting the space of the upper carrier tray. Thus, the height of the storage space can be adjusted according to the size of the dried material, and the use space is saved.
[0023] 2. The adjustable carrier table for vacuum freeze-drying is provided with a connecting knob hinged to the control knob. The connecting knob is provided with a spiral hole, and at the same time, the carrier tray is provided with a docking knob, on which a spiral knob is installed.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Example 1
[0031] Please refer to Figures 1-3 As shown, the adjustable stage for vacuum freeze-drying proposed in this embodiment includes a tabletop assembly 1 and a support assembly 2. The tabletop assembly 1 includes a plurality of loading trays 101. Docking buttons 103 are provided on the plurality of loading trays 101, and screw buttons 104 are fixed on the docking buttons 103. The plurality of loading trays 101 are designed in a stacked manner, which can provide a multi-layer placement space for the objects to be dried, utilize the space, and save the occupied space.
[0032] The support assembly 2 includes support rods 201 installed between the plurality of loading trays 101. A stabilizing hole 202 is formed in the support rod 201, and an extension rod 203 is threadedly connected in the stabilizing hole 202. A control button 204 is fixed at one end of the extension rod 203. A connection button 205 is movably hinged at one end of the control button 204. A screw hole 206 is formed in the connection button 205, and the screw hole 206 is threadedly connected to the screw button 104. The support rod 201 realizes the setting of the spacing between the multi-layer loading trays 101. At the same time, by rotating the extension rod 203, the extension rod 203 can be telescopically moved to adjust the distance between two adjacent loading trays 101 to meet the storage of larger and smaller items. When loading larger items, the extension rod 203 extends to increase the spacing height between adjacent loading trays 101. When loading smaller items, the extension rod 203 retracts to reduce the spacing height between adjacent loading trays 101, saving the use space.
[0033] The working principle of the adjustable carrier table for vacuum freeze-drying proposed in this embodiment is as follows: During use, with multiple carrier trays 101 provided, the carrier trays 101 are stacked, and a support assembly 2 is installed between adjacent carrier trays 101. The connecting knob 205 at the top end of the support rod 201 is threadedly connected to the screw knob 104 provided at the bottom of the upper-layer carrier tray 101 through the spiral hole 206 opened, and the connecting knob 205 at the bottom end of the support rod 201 is threadedly connected to the screw knob 104 provided on the top surface of the lower-layer carrier tray 101 through the spiral hole 206 opened, so as to achieve equidistant installation between multiple carrier trays 101. After the installation is completed, the distance between adjacent carrier trays 101 is adjusted according to the size of the item to be vacuum freeze-dried. By rotating the control knob 204 clockwise, under the action of the connecting force that the extension rod 203 is threadedly connected to the internal thread of the stabilizing hole 202 through the side thread, the extension rod 203 extends, realizing the expansion of the distance between adjacent carrier trays 101. Place the item to be dried with a larger size on the bottom carrier tray 101 of the two adjacent carrier trays 101. By rotating the control knob 204 counterclockwise, under the action of the connecting force that the extension rod 203 is threadedly connected to the internal thread of the stabilizing hole 202 through the side thread, the extension rod 203 is retracted into the support rod 201, reducing the distance between adjacent carrier trays 101. Then place the smaller item on the bottom carrier tray 101 of the two adjacent carrier trays 101. When placing the item, by rotating the limit sliding knob 210, the limit sliding knob 210 is closely attached to the side of the limit rib 208 to fix the length position of the extension rod 203. Embodiment 2
[0034] Please refer to Figures 1-3 As shown in the figure, for the adjustable carrier table for vacuum freeze-drying proposed in this embodiment, on the basis of Embodiment 1, this embodiment further includes that through holes 102 are opened on the carrier trays 101. Among the multiple carrier trays 101, partition buttons 105 are provided on the topmost and bottommost carrier trays 101. Among the multiple carrier trays 101, a hinge button 106 is provided on the topmost carrier tray 101. A carrying handle 107 is movably hinged on the hinge button 106. A limit sliding groove 207 is opened on the side of the support rod 201, and the limit sliding groove 207 penetrates through the stabilizing hole 202. At the same time, one end of the extension rod 203 is movably hinged with a stabilizing button 209. A limit sliding knob 210 is threadedly connected to the side of the stabilizing button 209, and the limit sliding knob 210 is slidably connected in the limit sliding groove 207. A limit rib 208 is provided in the limit sliding groove 207, and the limit sliding knob 210 is attached to the side of the limit rib 208.
[0035] In this solution, through holes 102 are provided on multiple loading trays 101 to achieve the effect of ventilation, ensuring that the side of the drying object placed above, which is close to the loading tray 101, can maintain good ventilation and ensure the dryness of the object. The partition button 105 plays a role in restricting installation and at the same time has an anti-slip layer. When the partition button 105 at the bottom fits on the tabletop, the frictional resistance between it and the contact surface is increased, avoiding the phenomenon that the loading platform slides and causes tipping. By pulling the handle 107, the whole device can be lifted, making it convenient to move to the required position. When it is not necessary to move, the handle 107 can be tilted and folded to either side, saving the top space. When the extension rod 203 rotates, under the action of the threaded connection with the stable hole 202, the extension rod 203 gradually extends, and at the same time drives the stable button 209 to slide in the stable hole 202. At this time, the limit slide button 210 slides in the limit chute 207, preventing the extension rod 203 from driving the stable button 209 to rotate simultaneously and improving the stability of the telescopic movement of the extension rod 203. When the extension rod 203 moves outwards to an appropriate length, the limit slide button 210 stays at the corresponding position in the limit chute 207. At this time, by rotating the limit slide button 210, the limit slide button 210 is pressed against the side of the limit rib 208, thus fixing the position adjusted by the extension rod 203 and preventing the extension rod 203 from freely telescoping. By rotating the limit slide button 210 clockwise, the position of the extension rod 203 is fixed, while by rotating the limit slide button 210 counterclockwise, the extension rod 203 can freely telescope and move.
[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
