DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7The utility model provides a technical solution: a freeze dryer that is easy to adjust the layer spacing, including a freeze dryer body 1, a freeze drying plate 2, a fixed long plate 3, a movable ring 4, a fixed column 5, a connecting rod 6, a movable plate 7, a limit block 8, a spring 9, a fixing pin 10, a pull ring 11, an anti-slip mechanism 12, an anti-slip block 13, a first fixed block 14, an anti-slip rod 15 and a second fixed block 16.

[0032] When using the freeze dryer that is easy to adjust the layer spacing, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a plurality of freeze-drying trays 2 are arranged inside the freeze-drying machine body 1, and the left and right ends of the freeze-drying trays 2 are connected to the slots between the fixed long plates 3, and at the same time, the side of the fixed long plates 3 is fixedly connected with a movable ring 4. First, according to the volume of the stored items, by pulling the pull ring 11, the pull ring 11 drives the movable plate 7 to move on the outside of the connecting rod 6, and the movable plate 7 slides between the limit block 8, and the movable plate 7 squeezes the spring 9, so that the spring 9 undergoes elastic deformation. At this time, the movable plate 7 drives the fixed pin 10 to extend and retract in the freeze-drying machine body 1, so that the fixed pin 10 is pulled out of the fixed groove on the inner wall of the freeze-drying machine body 1, thereby releasing the limit between the movable ring 4 and the fixed column 5;

[0033] Then, according to the needs, by pulling the freeze-drying plate 2, the freeze-drying plate 2 drives the movable ring 4 and the fixed column 5 to slide up and down through the fixed long plate 3, and the position of the freeze-drying plate 2 inside the freeze-drying machine body 1 is adjusted to achieve the adjustment of the spacing between the freeze-drying plate 2 and the freeze-drying plate 2 at the downward connected position, so as to facilitate the storage of objects of different sizes. When the position adjustment of the freeze-drying plate 2 is completed, the pull ring 11 is directly released, and the spring 9 restores its elastic deformation at this time, pushing the movable plate 7 to move, so that the movable plate 7 drives the fixing pin 10 to engage in the fixing grooves at the corresponding upper and lower positions of the inner side wall of the freeze-drying machine body 1, which are not drawn in the figure, thereby facilitating the limiting of the movable ring 4 and the fixed column 5, fixing the freeze-drying plate 2 at the corresponding position in the freeze-drying machine body 1. After the limiting is completed, the corresponding object is directly placed in the freeze-drying plate 2, and then the cabinet door on the front side of the freeze-drying machine body 1 is closed, and the object is freeze-dried;

[0034] When you need to take items, combine Figure 6 and Figure 7As shown, the anti-slipping mechanism 12 includes an anti-slipping block 13 fixedly connected to the rear end of the freeze-drying tray 2, a first fixed block 14 fixedly connected to the outer side of the front end of the fixed long board 3, an anti-slipping rod 15 hingedly connected to the middle part of the first fixed block 14, and a second fixed block 16 fixedly connected to the inner side of the front end of the fixed long board 3. After opening the cabinet door, the freeze-drying tray 2 is pulled forward, and the fixed long boards 3 slide with each other, and the anti-slipping block 13 and the fixed long boards 3 are connected by a slot, and the freeze-drying tray 2 drives the anti-slipping block 13 to move with the fixed long board 3. When the freeze-drying tray 2 is placed on the front side of the fixed long board 3, the anti-slipping rod 15 is set to block the anti-slipping block 13, thereby preventing the freeze-drying tray 2 from being directly pulled out of the freeze-drying machine body 1, and avoiding the freeze-drying tray 2 from falling off from the fixed long board 3, causing the items inside the freeze-drying tray 2 to fall and cause pollution;

[0035] In addition, when the freeze-drying tray 2 needs to be cleaned, the anti-detachment rod 15 can be flipped and rotated with the first fixed block 14. At this time, the torsion spring at the connection between the anti-detachment rod 15 and the first fixed block 14 is elastically deformed, and the anti-detachment rod 15 is disengaged from the second fixed block 16, thereby releasing the limit on the anti-detachment block 13, and then the freeze-drying tray 2 is continued to be pulled forward, and the freeze-drying tray 2 is completely pulled out of the fixed long plate 3, so that it is convenient to clean the inside of the freeze-drying tray 2 to prevent residue.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
