[0009] The dehumidification component is slidably connected to the reinforcement frame. When the insulation carton is in a humid environment or when the surface is wet, the dehumidification component absorbs moisture and reduces the temperature inside the insulation carton.
[0010] The assembling components are slidably connected to the reinforcement frame, and the assembling components in the two groups of insulation cartons are engaged with each other and are used to cooperate with the reinforcement frame to achieve that the two groups of insulation cartons can limit each other when placed.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0031] See also Figures 1 to 7 , an insulation carton with a built-in reinforcement frame, comprising:
[0032] A thermal insulation carton 1 is provided with a reinforcement frame 2 installed inside the thermal insulation carton 1, and a film 11 is wrapped around the surface of the reinforcement frame 2;
[0033] The tightening component 3 is connected to the surface of the reinforcement frame 2 and is used to cooperate with the reinforcement frame 2 to tighten the film 11;
[0034] The dehumidification component 4 is slidably connected to the reinforcement frame 2. When the thermal insulation carton 1 is in a humid environment or when the surface is wet, the dehumidification component 4 absorbs moisture and reduces the temperature inside the thermal insulation carton 1.
[0035] The assembling components 5 are slidably connected to the reinforcement frame 2, and the assembling components 5 in the two groups of insulation cartons 1 are mutually engaged and connected, and are used to cooperate with the reinforcement frame 2 to achieve mutual limitation of the two groups of insulation cartons 1 when placed.
[0036] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the reinforcement frame 2 includes:
[0037] The lower frame 21 is slidably connected to the interior of the thermal insulation carton 1;
[0038] The rotating shaft 231 has a lower end surface connected to the lower frame 21 by a thread, and the surface is rotatably connected to the side frame 23. The side frame 23 is provided with a film groove 232, and the film 11 passes through the interior of the film groove 232;
[0039] The upper frame 22 is connected to the upper end of the rotating shaft 231 through threads.
[0040] In this embodiment, the thermal insulation carton is a packaging material that combines the lightness and thermal insulation function of the thermal insulation carton and is widely used in the fields of cold chain transportation, fresh food, medicine, etc. When assembling the reinforcement frame 2, the lower frame 21 is placed on the ground, such as Figure 2 As shown, two sets of rotating shafts 231 are placed at the four corners of the lower frame 21, and the upper frame 22 is placed on the upper ends of the rotating shafts 231. The side frames 23 are rotated so that the lower ends of the rotating shafts 231 and the lower frame 21 are tightly connected by threads, and the upper ends of the rotating shafts 231 and the upper frame 22 are tightly connected by threads.
[0041] By installing the lower frame 21, upper frame 22, and side frames 23 within the insulation carton 1, deformation of the lower layer of insulation cartons 1 can be prevented when stacking (especially when bearing a load exceeding 20 kg), thereby improving the compression resistance of the insulation cartons 1. The reinforcement frame 2 is detachable for easy recycling and reuse. If the outer insulation carton 1 is damaged, it can be reused by simply replacing it with a new one, reducing production costs.
[0042] like Figure 3 As shown, after the reinforcement frame 2 is assembled, the ends of the film 11 are sequentially passed through each set of film slots 232, and the film 11 is connected end to end to complete the installation of the film 11. Finally, the assembled reinforcement frame 2 is placed inside the insulation carton 1, completing the assembly of the insulation carton 1 and the reinforcement frame 2. By passing the film 11 through the inside of each set of side frames 23, the food or medicine inside the insulation carton 1 can be physically waterproofed, while also improving the sealing of the insulation carton 1.
[0043] By wrapping the film 11 on the reinforced frame 2, the food and medicine in the thermal insulation carton 1 can be waterproofed. At the same time, the cold air leakage caused by insufficient density of the thermal insulation layer (such as foam, pearl cotton, aerogel, etc.) of the thermal insulation carton 1 or unreasonable design of the seams and seals can be reduced, thereby increasing the insulation time by more than 20% and meeting the needs of long-distance transportation.
[0044] In one embodiment of the present invention, Figure 5 As shown, the tightening assembly 3 includes:
[0045] The fixed wheel 31 is fixed to the surface of the side frame 23;
[0046] The sliding wheel 32 is slidably connected to the surface of the side frame 23. The sliding wheel 32 and the lower frame 21 are connected by an elastic member 33. The elastic member 33 is a compression spring. The sliding wheel 32 and the surface of the side frame 23 are slidably connected by a spline sleeve and a spline shaft.
[0047] The pawls 35 are connected to the sides of the fixed rotating wheel 31 and the sliding rotating wheel 32, and the two sets of pawls 35 are engaged with each other;
[0048] The first gears 34 are fixed on the surfaces of two adjacent sets of side frames 23 , and the two sets of first gears 34 are meshed and connected.
[0049] In this embodiment, after the film 11 is connected end to end, the two sets of side frames 23 at the ends of the film 11 are rotated so that the side frames 23 drive the two ends of the film 11 to be rolled up through the film grooves 232, thereby automatically tightening and fixing the two ends of the film 11.
[0050] like Figure 5 As shown, the side frame 23 on the left side is rotated counterclockwise, and this group of side frames 23 will drive the pawl 35 on the lower side to rotate through the fixed wheel 31. Since one side of the pawl 35 is an inclined surface and the other side is a vertical surface, relative rotation will occur between the fixed wheel 31 and the sliding wheel 32. At the same time, the sliding wheel 32 can compress the elastic member 33 below, so that this group of side frames 23 can roll up one end of the film 11.
[0051] like Figure 5 As shown, the inclined surfaces of the two groups of pawls 35 are set in opposite directions. Since the two groups of first gears 34 are meshed and connected, an adjacent group of side frames 23 will rotate in the opposite direction under the action of the two groups of first gears 34, so that the other group of side frames 23 can reel in the other end of the film 11 until both ends of the film 11 are tightened and fixed.
[0052] After both ends of the film 11 are tightened and fixed, the two sets of sliding wheels 32 will slide upward on the surface of the side frame 23 under the elastic force of the elastic member 33 until the pawls 35 on both sides of the sliding wheel 32 and the fixed wheel 31 engage with each other. Since the sliding wheel 32 can only slide up and down under the action of the spline sleeve and the spline shaft, and cannot rotate on the surface of the side frame 23, the side frame 23 is limited by the action of the fixed wheel 31 and the sliding wheel 32, preventing the film 11 on the side frame 23 from loosening.
[0053] In one embodiment of the present invention, Figure 5 As shown, the dehumidification component 4 includes:
[0054] The water collecting tank 41 is provided inside the lower frame 21 and has a sliding groove 42 on the side;
[0055] The sliding shaft 43 is rollingly connected to the inside of the sliding groove 42, and a dehumidification bag 44 is wrapped around the surface. The dehumidification bag 44 is filled with a composition of gel, urea, and calcium chloride. The weight percentages of the various components in the composition of the dehumidification bag 44 are as follows: 30%-45% gel, 30%-45% urea, and 10%-40% calcium chloride.
[0056] In this embodiment, the weight percentages of the components of the composition in the dehumidifying bag 44 are 40% gel, 40% urea, and 20% calcium chloride. When the insulation carton 1 is in a humid environment or when the surface is exposed to water, the water on the surface of the insulation carton 1 will flow into the water collecting tank 41, and the sliding shaft 43 will slide to the lowest point of the sliding groove 42 under the action of gravity, so that the dehumidifying bag 44 on the surface of the sliding shaft 43 will come into contact with the water. The calcium chloride and silica gel inside the dehumidifying bag 44 will quickly absorb water when exposed to water, thereby drying the insulation carton 1 and reducing the insulation carton 1 from softening easily when exposed to water, or from becoming moldy or stratified in a humid environment. At the same time, urea and water undergo an endothermic reaction, thereby cooling the food and medicine in the insulation carton 1. The insulation carton 1 is highly safe, reusable, and non-toxic, and can minimize the risks brought by the insulation carton being exposed to water, thereby ensuring the safety and effectiveness of food and medicine.
[0057] Furthermore, the dehumidification bag 44 is adhered to the surface of the sliding shaft 43 by means of adhesive tape, so that the dehumidification bag 44 can be replaced regularly.
[0058] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the assembly component 5 includes:
[0059] The fixing frame 51 is connected to the surface of the upper frame 22 and is internally rotatably connected to two sets of rotating shafts 52;
[0060] The clamping frames 53 are mounted on the surfaces of the two sets of rotating shafts 52, and the sides of the two sets of clamping frames 53 are provided with clamping grooves 54;
[0061] The adjustment rack 56 is slidably connected to the interior of the fixing frame 51, and the end thereof is connected to the inner wall of the fixing frame 51 via a spring 57;
[0062] The second gear 55 is mounted on the surface of the two sets of rotating shafts 52, and the two sets of second gears 55 are meshed with the adjustment rack 56;
[0063] The positioning frame 58 is connected to the side of the upper frame 22 away from the fixing frame 51. The surface of the positioning frame 58 is engaged and connected to the two groups of clamping grooves 54 where another group of insulation cartons 1 are located. Two groups of avoidance grooves 10 are opened on the insulation cartons 1, and the fixing frame 51 and the positioning frame 58 are respectively located on the inner sides of the two groups of avoidance grooves 10.
[0064] In this embodiment, if Figure 6As shown, when the user lifts the insulation carton 1, the user pulls the adjustment rack 56 outward with his fingers at the position of the avoidance groove 10, so that the adjustment rack 56 slides out of the insulation carton 1, so that the insulation carton 1 can be lifted by the adjustment rack 56, and the force point can be transferred to the reinforcement frame 2, thereby avoiding the insulation carton 1 from breaking at the position of the avoidance groove 10.
[0065] When two insulation cartons 1 are stacked adjacent to each other, the adjustment rack 56 is first pulled outward, and the adjustment rack 56 stretches the spring 57. At the same time, the two sets of second gears 55 drive the corresponding two sets of rotating shafts 52 to rotate under the action of the adjustment rack 56, and the two sets of rotating shafts 52 drive the clamping frame 53 to open (such as Figure 6 status).
[0066] like Figure 7 As shown, after placing two groups of insulation cartons 1 adjacent to each other, loosen the adjusting rack 56. At this time, the adjusting rack 56 will slide toward the inside of the fixing frame 51 under the pull of the spring 57, so that the two groups of clamping frames 53 are retracted until the clamping grooves 54 on the sides of the two groups of clamping frames 53 are engaged with the surface of the positioning frame 58 on the other group of insulation cartons 1. In this way, multiple insulation cartons 1 can limit each other when placed, thereby improving the stability of the insulation cartons 1 during transportation.
[0067] The working principle of the present invention is as follows: by installing a lower frame 21, an upper frame 22, and a side frame 23 in the insulating carton 1, the lower layer of the insulating carton 1 can be prevented from being easily deformed when the insulating carton 1 is stacked, thereby improving the compressive resistance of the insulating carton 1. The reinforcement frame 2 is a detachable design, which is convenient for recycling and reuse. When the outer insulating carton 1 is damaged, it only needs to be replaced with a new insulating carton 1 to be reused, thereby reducing production costs. By wrapping a film 11 around the reinforcement frame 2, the food and medicine in the insulating carton 1 can be waterproofed, and at the same time, the leakage of cold air from the insulating carton 1 can be reduced, thereby increasing the insulation time by more than 20%, meeting the needs of long-distance transportation.
[0068] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, or mutual communication; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components.
