[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-5 The present invention provides the following two preferred embodiments:

[0021] Example 1: A box-type vacuum freeze dryer includes: a material cover 1 and a body 2. The material cover 1 is connected to the body 2. An installation hole 3 is provided on the end wall of the material cover 1, and a thermometer 4 is inserted into the installation hole 3. An installation protrusion 5 is fixedly sleeved on the periphery of the thermometer 4. The thermometer 4 is mounted on the material cover 1 via a connecting assembly for monitoring the internal temperature of the box-type vacuum freeze dryer. Positioning grooves 6 are equidistantly arranged in a ring on the end wall of the installation protrusion 5. An externally threaded tube 7 in the connecting assembly is fixedly mounted on the end wall of the material cover 1. The installation hole 3 is located at the center of the inner ring of the externally threaded tube 7. A sealing gasket 8 is inserted into the inner wall of the externally threaded tube 7 to ensure a sealing effect during the installation of the thermometer 4. The installation protrusion 5 is inserted into the externally threaded tube 7 for positioning and installation of the thermometer 4. The sealing gasket 8 is engaged with the installation protrusion 5 for compression sealing. The sealing gasket 8 ensures a sealing effect. A guide groove 9 is equidistantly annularly formed on the side wall of the external threaded pipe 7, and a slot 10 is formed on the bottom wall of the guide groove 9. An L-shaped plate 11 is engaged within the slot 10, engaging with the material cover 1. A sliding groove 12 is formed on the side wall of the L-shaped plate 11, and a positioning plate 13 is fixedly set on the side wall of the L-shaped plate 11. The end of the positioning plate 13 is inclined to provide guidance, and the positioning plate 13 is engaged within the guide groove 9. The positioning plate 13 engages with the positioning groove 6, fixing the position of the mounting convex ring 5 while ensuring that the mounting convex ring 5 squeezes the sealing gasket 8. A slider 14 is equidistantly annularly fixed on the end wall of the material cover 1, and a limit block 15 is fixedly set at the top of the slider 14. The slider 14 is movably engaged with the sliding groove 12, and the limit block 15 is engaged with the L-shaped plate 11, enabling the L-shaped plate 11 to be stably and movablely set on the material cover 1.

[0022] In use, insert the sealing gasket 8 into the inner wall of the external threaded pipe 7 and engage it with the material cover 1. Insert the thermometer 4 into the mounting hole 3 on the material cover 1 until the mounting protrusion 5 is inserted into the external threaded pipe 7 and squeezes the sealing gasket 8. Move the positioning plate 13 along the guide groove 9 until the L-shaped plate 11 engages with the slot 10. At this time, the positioning plate 13 engages with the positioning groove 6 on the mounting protrusion 5 to fix the position of the mounting protrusion 5 and ensure that the mounting protrusion 5 squeezes the sealing gasket 8. The end of the positioning plate 13 is set with a bevel to guide it and facilitate its insertion into the positioning groove 6. The slider 14 engages with the slide groove 12 and the limit block 15 engages with the L-shaped plate 11 to ensure the stability of the movement of the L-shaped plate 11. After that, the L-shaped plate 11 is limited, and the thermometer 4 is fixedly installed on the material cover 1. When the box-type vacuum freeze dryer body 2 is working, it monitors the internal temperature of the body 2. The operation is simple and it is easy to quickly replace the thermometer 4 if it is damaged, so as not to affect the normal use of the device.

[0023] Example 2: Based on Example 1, the threaded sleeve 16 is threaded onto the external threaded tube 7. The outer wall of the threaded sleeve 16 is provided with raised grooves to facilitate rotation. The threaded sleeve 16 is engaged with the L-shaped plate 11 to limit the L-shaped plate 11 and prevent the L-shaped plate 11 from separating from the slot 10. An annular groove 17 is provided on the peripheral wall of the threaded sleeve 16. An elastic hook 18 is fixedly provided on the side wall of the material cover 1. The elastic hook 18 is engaged with the annular groove 17 to help fix the position of the threaded sleeve 16.

[0024] In use, the L-shaped plate 11 is inserted into the slot 10, and the positioning plate 13 is engaged with the positioning groove 6 to limit the installation of the mounting ring 5. Then, the threaded sleeve 16 is threaded onto the external threaded tube 7 until the bottom wall of the threaded sleeve 16 is engaged with the horizontal plate of the L-shaped plate 11. At this time, the external threaded tube 7 limits the L-shaped plate 11 to prevent it from separating from the slot 10, ensuring that the positioning plate 13 and the positioning groove 6 are stably engaged. At the same time, the elastic hook 18 is engaged with the annular groove 17 on the threaded sleeve 16, further ensuring the fixed position of the external threaded tube 7, thereby ensuring the installation stability of the thermometer 4.
