The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides a door sealing device for a vacuum freeze-drying machine box, as Figures 1-4 shown, which includes a door body 1. One side of the door body 1 is hinged with a hinge 2. One end of the door body 1 is provided with a sealing strip 4. A reinforcement structure 5 is arranged inside the sealing strip 4. Disassembly and assembly structures 3 are arranged at the top and bottom ends of one end of the door body 1.

[0023] It should be noted that due to the problem of unstable installation and disassembly of the box door sealing strip, in this solution, by setting the disassembly and assembly structure 3, there are four groups of reserved slots 301, which are evenly arranged inside one end of the door body 1. The bottom end of the connecting piece 302 is fixed on the outer side wall of the sealing strip 4. Through the engaging structure of the reserved slot 301 and the connecting piece 302, the connecting piece 302 is correspondingly engaged inside the reserved slot 301, making the limit of the sealing strip 4 more stable. Then, through the stacking and screwing of the bolts 303, the limiting piece 304 limits the connecting piece 302, making the installation and disassembly of the sealing strip 4 more convenient.

[0024] Specifically, in this embodiment, the solution mainly includes a disassembly and assembly structure 3. The disassembly and assembly structure 3 includes a reserved groove 301, which is arranged inside the top and bottom ends of one end of the door body 1. A connecting piece 302 is arranged inside the reserved groove 301. Limit pieces 304 are arranged at the top and bottom ends of one end of the door body 1. A clamping block 305 is arranged at the other end of the limit piece 304. Bolts 303 are arranged inside both ends of the limit piece 304. First, reserve grooves 301 are equally spaced and opened inside one end of the door body 1. Then, the connecting pieces 302 are evenly fixed on the outer side wall of the sealing strip 4. Then, the connecting pieces 302 are clamped inside the reserved grooves 301 to limit the sealing strip 4. Then, the clamping blocks 305 are symmetrically fixed at the other end of the limit pieces 304. The corresponding limit pieces 304 are placed at one end of the reserved groove 301. Then, the bolts 303 are symmetrically screwed into the limit pieces 304 to limit the connecting pieces 302, making the sealing device of the vacuum freeze-drying machine door more convenient for installation and disassembly.

[0025] In a further preferred embodiment of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, the inner diameter of the reserved groove 301 is larger than the outer diameter of the connecting piece 302. The reserved groove 301 and the connecting piece 302 form a clamping structure. There are four groups of limit pieces 304, and the four groups of limit pieces 304 are evenly distributed at one end of the door body 1. Through the clamping structure of the reserved groove 301 and the connecting piece 302, it is convenient to limit the connecting piece 302. The uniform distribution of the limit pieces 304 makes the limit of the connecting piece 302 more stable.

[0026] Specifically, in this embodiment, the solution mainly includes a reinforcement structure 5. The reinforcement structure 5 includes a reinforcement strip 501, which is arranged inside the sealing strip 4. A reserved cavity 502 is arranged at the top end inside the reinforcement strip 501. A reinforcing rubber strip 503 is arranged inside the reserved cavity 502. Reserved holes 504 are arranged at the bottom end inside the reinforcement strip 501. First, the reserved holes 504 are equally spaced and opened at the bottom end inside the reinforcement strip 501. Then, the reserved cavity 502 is opened at the top end inside the reinforcement strip 501. Then, the reinforcing rubber strip 503 is clamped inside the reserved cavity 502. Then, the reinforcement strip 501 is limited inside the sealing strip 4 to reinforce the sealing strip 4 and extend the service life of the sealing strip 4.

[0027] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 4As shown, a plurality of reserved holes 504 are provided, and the plurality of reserved holes 504 are evenly distributed inside the bottom end of the reinforcing strip 501. The inner diameter of the reserved cavity 502 is larger than the outer diameter of the reinforcing rubber strip 503. The reserved cavity 502 and the reinforcing rubber strip 503 form a snap-fit structure. The uniform distribution of the reserved holes 504 improves the elasticity of the reinforcing strip 501. The snap-fit structure of the reserved cavity 502 and the reinforcing rubber strip 503 enables the reinforcing rubber strip 503 to be limited inside the reinforcing strip 501, thereby limiting the reinforcing rubber strip 503.
