[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses a mobile freeze dryer. (Refer to...) Figure 1 and Figure 7 A mobile freeze dryer includes a freeze dryer body 1, which includes a freeze dryer 101. The bottom of the freeze dryer 101 is fixedly connected with four casters 102. An operation panel 103 is fixedly connected to the surface of the freeze dryer 101. A glass cover 104 is movably connected to the top of the freeze dryer 101. An adjustment mechanism 2 is provided in the inner cavity of the glass cover 104. The surface of the adjustment mechanism 2 is movably connected to the inner cavity of the freeze dryer 101.

[0028] The adjustment mechanism 2 includes a second fixed plate 207, which is movably connected to the inner cavity of the freeze dryer 101. Two fixed rods 204 are fixedly connected to the surface of the second fixed plate 207. The surfaces of the two fixed rods 204 are movably connected to a first fixed plate 201. A motor 210 is fixedly connected to the surface of the first fixed plate 201. The output end of the motor 210 passes through the inner cavity of the first fixed plate 201 and is fixedly connected to a threaded rod 203. One end of the threaded rod 203 is movably connected to the surface of the second fixed plate 207. Four shelf plates 206 are threadedly connected to the surface of the second fixed plate 207.

[0029] Reference Figure 3 and Figure 4 A protective cover 202 is fixedly connected to the surface of the motor 210. The bottom of the protective cover 202 is fixedly connected to the top of the first fixed plate 201. The protective cover 202 is used to protect the motor 210 and prevent the motor 210 from being affected by low temperature. At the same time, the protective cover 202 fixes the position of the motor 210 and prevents the motor 210 from shaking during operation.

[0030] Reference Figure 3 and Figure 4 The bottom of the first fixed plate 201 is fixedly connected with a guide post 205. One end of the guide post 205 is fixedly connected to the top of the second fixed plate 207. There are two guide posts 205. The surface of the guide post 205 is movably connected to the inner cavity of the shelf 206. The guide post 205 guides and limits the movement of the shelf 206, preventing the threaded rod 203 from rotating and instead moving the shelf 206 to the surface of the threaded rod 203, thus adjusting the spacing between each shelf 206.

[0031] Reference Figure 3A bearing 208 is fixedly connected to the surface of the threaded rod 203. The outer ring of the bearing 208 is fixedly connected to the top of the second fixed plate 207. The bearing 208 provides a limiting support for the threaded rod 203 and improves the stability of the threaded rod 203 during rotation.

[0032] Reference Figure 5 and Figure 6 A handle 209 is movably connected to the inner cavity of the first fixed plate 201. The surface of the handle 209 is made of flocked material. A rotating shaft 212 is fixedly connected to the inner cavity of the handle 209. There are two rotating shafts 212. The surface of the rotating shaft 212 is movably connected to the inner cavity of the first fixed plate 201. By setting the handle 209 and the rotating shaft 212 to work together, the handle 209 can be pulled to make the handle 209 drive the rotating shaft 212 to rotate on the surface of the first fixed plate 201. When the handle 209 rotates from a horizontal state to a vertical state, it can indirectly drive the first fixed plate 201 to move, thereby driving the entire adjustment mechanism 2 to move. Due to the flocked material on the surface of the handle 209, the operator is prevented from being frostbitten when pulling the handle 209.

[0033] Reference Figure 6 Each rotating shaft 212 has two torsion springs 213 fitted on its surface. One end of the torsion spring 213 is fixedly connected to the surface of the handle 209, and the other end of the torsion spring 213 is fixedly connected to the inner cavity of the first fixed plate 201. Through the torsion spring 213, due to the elastic torque of the torsion spring 213, the handle 209 will always rotate in the inner cavity of the first fixed plate 201 without the action of external force.

[0034] Reference Figure 5 The surface of the first fixing plate 201 is provided with a semi-circular groove 211. The lowest point of the semi-circular groove 211 is lower than the surface of the handle 209. The semi-circular groove 211 facilitates the operator to pull the handle 209 to rotate through the inner cavity of the semi-circular groove 211.

[0035] Reference Figure 4 and Figure 7The surfaces of the shelf 206 and the second fixing plate 207 are both fixedly connected to fixing strips 214. There are several fixing strips 214. An extension strip 216 is movably connected to the inner cavity of each fixing strip 214. A damping block 215, made of rubber, is fixedly connected to one end of each extension strip 216. The surface of the damping block 215 is movably connected to the inner cavity of the fixing strip 214. A fixing block 217 is fixedly connected to the surface of the extension strip 216. By setting the fixing strips 214, damping blocks 215, and extension strips 216... The extension strip 216 and the fixing block 217 are configured so that after materials are placed on the surfaces of the storage plate 206 and the second fixing plate 207, the fixing block 217 is pulled to drive the extension strip 216 to slide in the inner cavity of the fixing strip 214, thereby blocking the materials on the surfaces of the storage plate 206 and the second fixing plate 207 and preventing the materials from falling off the surfaces of the storage plate 206 and the second fixing plate 207 when the adjustment mechanism 2 is moved. Through the damping of the damping block 215, the extension strip 216 can be damped and fixed after sliding in the inner cavity of the fixing strip 214.

[0036] Working principle: When the freeze dryer body 1 needs to dry large pieces of material, the spacing between the various placement plates 206 needs to be adjusted. At this time, the motor 210 starts working, driving the threaded rod 203 to rotate through the output end of the motor 210. Because the surface of the threaded rod 203 is threadedly connected to the inner cavity of the placement plate 206, and the position of the placement plate 206 is restricted by the guide post 205 and will not be rotated by the threaded rod 203, each placement plate 206 can be moved on the surface of the threaded rod 203 when the threaded rod 203 rotates. When the shelf 206 is adjusted to the appropriate position, pull the fixing block 217. The fixing block 217 causes the extension strip 216 to slide into the inner cavity of the fixing strip 214. Then, place materials onto the surfaces of the shelf 206 and the second fixing plate 207. After placement, pull the fixing block 217 in the opposite direction, causing the extension strip 216 to slide out of the inner cavity of the fixing strip 214 and block the materials placed on the surfaces of the shelf 206 and the second fixing plate 207. Then, pull the handle 209 to rotate the rotating shaft 212 within the inner cavity of the first fixing plate 201. The handle 209 indirectly drives the adjustment mechanism 2 to move and places the adjustment mechanism 2 in the inner cavity of the freeze dryer body 1. Then, the handle 209 is released, and due to the elastic torque of the torsion spring 213, the handle 209 is rotated back to the inner cavity of the first fixed plate 201. Then, the glass cover 104 is placed on the surface of the adjustment mechanism 2. Finally, the freeze dryer body 1 operates to freeze the materials placed on the placement plate 206 and the second fixed plate 207. When the freezing is completed, the glass cover 104 is lifted so that it is no longer placed on the surface of the first fixed plate 201. The outer side of the adjustment mechanism 2 is then connected to the handle 209 via the semi-circular groove 211. Due to the flocked material on the surface of the handle 209, workers are prevented from getting frostbite when picking it up. The handle 209 drives the rotating shaft 212 to rotate within the cavity of the first fixed plate 201. The rotating shaft 212 drives the first fixed plate 201 to move, thereby lifting the entire adjustment mechanism 2 for movement. When the worker puts down the adjustment mechanism 2 and does not apply force to the handle 209, the elastic torque of the torsion spring 213 causes the handle 209 to rotate back into the cavity of the first fixed plate 201.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
