At this time, the top outer wall of the foam inner column 7 will be against the inner wall position of the box cover 3. The staff needs to press the box cover 3 hard to completely cover the box cover 3 and the foam plastic box 1. At this time, the foam inner column 7 will also be pressed in the limiting outer column 6 and move downward.

[0038] In the present invention, when the foam plastic box 1 and the box cover 3 are completely covered, the staff twists the torsion switch 25 to rotate the limit clamp 26 half a circle. Due to the special shape of the limit clamp 26, the rotating limit clamp 26 will be engaged with the inner wall of the slide groove 28 and push the latch 27 to both sides, so that the outer wall of one end of the latch 27 is pushed out of the placement cavity 29 and engaged inside the socket 30, thereby quickly fixing the connection between the foam plastic box 1 and the box cover 3 to prevent loosening.

[0039] Embodiment 3, on the basis of embodiment 2, the expansion component includes a fixed bottom plate 16, a second vacuum elastic bag 17, an axle 18, a fixed disc 19, a baffle 20, a plastic sealing tape 21, a traction plate 22 and a connecting tape 23, the bottom outer wall of the fixed bottom plate 16 is fixedly connected to the bottom inner wall of the foam plastic box 1, the bottom outer wall of the second vacuum elastic bag 17 is fixedly connected to the top outer wall of the fixed bottom plate 16, the bottom outer wall of the axle 18 is rotatably connected to the inner wall of the fixed bottom plate 16, the fixed disc 19 is located inside the second vacuum elastic bag 17, the bottom outer wall of the fixed disc 19 is fixedly connected to the bottom inner wall of the second vacuum elastic bag 17, the inner wall of the fixed disc 19 is rotatably connected to the outer wall of the axle 18, the outer wall of the plastic sealing tape 21 is fixedly connected to the outer wall of the axle 18, the outer wall of the plastic sealing tape 21 is adhered to the inner walls of the second vacuum elastic bag 17 and the fixed disc 19, and the plastic sealing tape 21 seals the second vacuum elastic bag 17 It is divided into two liquid-carrying chambers, which are respectively loaded with hydrohalogenated olefins and water. The outer wall of one end of the baffle 20 is fixedly connected to the outer wall of the shaft rod 18, and the outer wall of the baffle 20 is movably connected to the inner wall of the fixed disc 19. The outer wall of the baffle 20 is provided with a plurality of overflow holes 34. The traction plate 22 is located inside the fixed bottom plate 16. The outer wall of one end of the traction plate 22 is fixedly connected to the outer wall of one side of the shaft rod 18. The outer wall of one end of the connecting belt 23 is fixedly connected to the outer wall of one end of the traction plate 22. A traction groove 24 is provided inside the foam plastic box 1. The inner wall of the traction groove 24 is movably connected to the outer wall of the connecting belt 23. The outer wall of one end of the connecting belt 23 away from the shaft rod 18 is fixedly connected to the outer wall of one end of the limiting clamp 26. The outer walls of both sides of the foam plastic interlayer 2 are fixedly connected with movable rollers 5. The inner walls of both sides of the foam plastic box 1 are provided with limiting tracks 4. The inner wall of the limiting track 4 is movably connected to the outer wall of the movable roller 5.

[0040] In the present invention, when the staff rotates the torsion switch 25 half a circle, the limit clamp ring 26 will pull the connecting belt 23, and through the pulling of the connecting belt 23, the traction plate 22 can be rotated slightly with the shaft 18 as the axis. At the same time, the baffle 20 fixedly connected to the shaft 18 will rotate synchronously, and one side outer wall of the baffle 20 will abut against one side outer wall of the plastic sealing belt 21. By pulling, the connection between the plastic sealing belt 21 and the second vacuum elastic bag 17 and the drainage channel 9 is debonded and dropped, so that the two liquid-carrying cavities are connected to form the same liquid-carrying cavity, and the hydrohalogenated olefins and water in the two liquid-carrying cavities are mixed and reacted to form solid foam in the second vacuum elastic bag 17. The vacuum elastic bag 17 expands rapidly to wrap the finished ceramics. By opening an overflow hole 34 on the baffle 20, the baffle 20 is promoted to mix rapidly with the hydrohalogenated olefins and water while rotating. When the bottom of the finished ceramics is completely wrapped, the excess expansion thrust will push the foam plastic interlayer 2 to move upward. The sliding of the moving roller 5 is designed to reduce the moving friction of the foam plastic interlayer 2. Since the models and sizes of ceramics are various, the amount of expansion required to clamp small-volume ceramics and clamp large-volume ceramics is different. The present invention uses this sliding structure to improve the expansion adaptability of the present invention and ensure a high degree of protection for the ceramics.

[0041] Embodiment 4, based on embodiment 3, the connecting belt 23 in the expansion assembly of the box cover 3 is fixedly connected with a connecting protrusion 31, the top outer wall of the foam plastic box 1 is provided with a placement groove 32, and the connecting protrusion 31 is movably connected to the outer wall of one end of the limiting clamp 26.

[0042] In the present invention, when the foam plastic box 1 and the box cover 3 are closed, the connecting protrusion 31 will be located at the placement groove 32. The staff turns the torsion switch 25, and the outer wall of one end of the limit clamp 26 will press against the connecting protrusion 31 to push the connecting protrusion 31 into the annular groove 33. This device is used to pull through the connecting belt 23 of the expansion component in the box cover 3 to form a foam expansion reaction, which wraps and fixes the top position of the ceramic finished product.

[0043] The working principle and use process of the present invention: In the present invention, after the staff puts the finished ceramic product into the foam plastic box 1, the box cover 3 is placed on the foam plastic box 1. At this time, the top outer wall of the foam inner column 7 will be against the inner wall position of the box cover 3. The staff needs to press the box cover 3 hard to completely cover the box cover 3 and the foam plastic box 1. At this time, the foam inner column 7 will also be pressed in the limiting outer column 6 and move downward. The tearable opening sealing glue 13 on the triangular liquid-carrying bags 8 on both sides is torn open by the tape 14 as the foam inner column 7 moves downward. Due to the special shape of the triangular liquid-carrying bags 8, the liquid inside will flow out quickly. At this time, the hydrohalogenated olefins and water loaded in the two triangular liquid-carrying bags 8 are mixed and flow into the No. 1 vacuum elastic bag 15 through the circulation port 12 and the drainage channel 9 at the same time. These two materials are the main materials of foam expansion agents available on the market. Hydrogen halogenated olefins, as a chemical foaming agent, react with water to generate hydrogen during the preparation of polyurethane foam, thereby foaming the polymer. The gas produced by this reaction causes the polymer material to expand and form a porous structure. The addition of water promotes the foaming reaction. By controlling the ratio of water and hydrogen halogenated olefins, the density and expansion degree of the foam can be adjusted. In the present invention, this expansion method is used. After the foam plastic box 1 and the box cover 3 are closed, the No. 1 vacuum elastic bag 15 will wrap the outer walls of the ceramic product around the rapid expansion of the expansion agent, so that the ceramic package can be fixed between the foam plastic interlayer 2, thereby improving the protective performance. Hydrogen halogenated olefins and water are introduced into the When the water flows through the flow channel 9, the water flow will drive the stirring blade 11 to rotate, thereby further improving the mixing efficiency of the hydrohalogenated olefin and water. In the present invention, when the foam plastic box 1 and the box cover 3 are completely covered, the staff twists the torsion switch 25 to rotate the limit clamp 26 half a circle. Due to the special shape of the limit clamp 26, the rotating limit clamp 26 will be engaged with the inner wall of the slide groove 28 and push the latch 27 to both sides, so that the outer wall of one end of the latch 27 is pushed out of the placement cavity 29 and engaged inside the socket 30, thereby quickly fixing the connection between the foam plastic box 1 and the box cover 3 to prevent loosening. In the present invention, when the staff rotates the torsion switch 25 half a circle, the limit clamp 26 will pull the connecting belt 23, and through the pulling of the connecting belt 23, the traction plate 22 can be The shaft 18 rotates slightly with the shaft as the axis. At the same time, the baffle 20 fixedly connected to the shaft 18 rotates synchronously. One side outer wall of the baffle 20 contacts the one side outer wall of the plastic sealing tape 21. The plastic sealing tape 21 is pulled to make the connection between the second vacuum elastic bag 17 and the drainage channel 9 debond and fall off, so that the two liquid-carrying chambers are connected to form the same liquid-carrying chamber. The hydrohalogenated olefins and water in the two liquid-carrying chambers react with each other to form solid foam, which rapidly expands in the second vacuum elastic bag 17, thereby wrapping the finished ceramics. By opening an overflow hole 34 on the baffle 20, the baffle 20 is promoted to rapidly mix the hydrohalogenated olefins and water while rotating. When the bottom of the finished ceramics is completely wrapped, the excess expansion thrust pushes the foam plastic interlayer 2 to move upward.The sliding of the moving roller 5 is designed to reduce the moving friction of the foam plastic interlayer 2. Due to the various sizes of ceramics, the amount of expansion required to clamp small-volume ceramics and large-volume ceramics is different. The present invention uses this sliding structure to improve the expansion adaptability of the present invention and ensure the high protection of ceramics. In the present invention, when the foam plastic box 1 and the box cover 3 are closed, the connecting protrusion 31 will be located at the placement groove 32. The staff turns the torsion switch 25, and the outer wall of one end of the limit clamp 26 will resist the connecting protrusion 31 and push the connecting protrusion 31 into the annular groove 33. The connecting belt 23 of the expansion component in the box cover 3 is pulled through by this device to form a foam expansion reaction, which wraps and fixes the top position of the finished ceramic product.

[0044] 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.
