Description

Technical Field

[0001] The utility model relates to the technical field of insulation boxes, and specifically, to an advanced energy-saving EPS foam insulation box. Background Art

[0002] Existing insulation boxes are widely used in transportation and storage scenarios with strict temperature requirements for food, drugs, biological products, etc. The insulation performance is an important indicator to ensure the quality of items. Most traditional insulation boxes use EPS (expanded polystyrene) foam material as the insulation layer, which has good heat insulation performance. However, in practical applications, the following main problems still exist in existing insulation boxes:

[0003] Poor sealing effect: The connection between the box body and the box cover of most insulation boxes relies on simple buckling or mechanical connection, with insufficient sealing performance, which easily allows external air to enter, thereby affecting the internal insulation effect. In scenarios with high insulation requirements, such as pharmaceutical transportation, air infiltration will cause unstable internal temperature, affecting the activity of drugs or the freshness preservation effect of food.

[0004] Poor connection firmness: To ensure that the insulation box is not opened during transportation, adhesives or tapes are usually used for auxiliary fixation. Although this method can enhance the sealing of the insulation box to a certain extent, it also brings problems such as cumbersome operation and difficulty in repeated use. Each use of adhesives or tapes will damage the box body, reducing the service life of the insulation box, and during disassembly, it is easy to damage the outer surface of the box body or leave residual glue, affecting subsequent use.

[0005] Difficult to disassemble: During the use of existing insulation boxes, especially those with high sealing requirements, the disassembly is difficult and the operation is cumbersome. When the box needs to be frequently opened and closed, problems such as box cover deformation and structural damage are likely to occur, further reducing the reusability of the insulation box.

[0006] Lack of negative pressure sealing technology: Although some high-end insulation boxes have tried to introduce negative pressure sealing technology to improve the sealing effect, in practical applications, the designs of these insulation boxes are too complex, with high costs, and it is difficult to achieve efficient negative pressure environment control, unable to balance the sealing effect and the operation convenience of users.

[0026] According to an embodiment of the present utility model, an advanced energy-saving EPS foam insulation box is provided.

[0027] Embodiment 1;

[0028] As Figure 1-7 shown, the advanced energy-saving EPS foam insulation box according to an embodiment of the present utility model includes a box body structure 1, a box cover structure 2 is connected to the box body structure 1. The box body structure 1 includes a heat preservation box body 101, docking grooves 106 are formed on both sides of the heat preservation box body 101, a sealing structure 3 is connected to the docking grooves 106, and a limiting ring 4 is arranged in a matching manner with the sealing structure 3.

[0029] The box body structure 1 is hermetically connected to the box cover structure 2. The box body structure 1 is connected to the sealing structure 3 through the limiting ring 4. The sealing structure 3 can improve the sealing effect after the negative pressure docking of the box body structure 1 and the box cover structure 2.

[0030] A storage groove 102 is formed on the heat preservation box body 101 of the box body structure 1. A first fitting groove 103 is formed on the edge of the groove body of the storage groove 102. A sealing groove 104 is arranged outside the storage groove 102. The sealing groove 104 is formed on the heat preservation box body 101. A second convex block 105 is fixedly arranged on the edge of the groove body of the sealing groove 104. The docking groove 106 is communicated with the sealing groove 104.

[0031] The box cover structure 2 includes a heat preservation cover 201, a fitting convex block 202, a first convex block 203, a sealing block 204, and a second fitting groove 205. A fitting convex block 202 is fixedly arranged at one end of the heat preservation cover 201. A first convex block 203 is fixedly arranged on the peripheral side of the fitting convex block 202. A sealing block 204 is arranged on the outer peripheral side of the fitting convex block 202. A second fitting groove 205 is formed in the sealing block 204. The first convex block 203 is fitted with the first fitting groove 103, and the second convex block 105 is fitted with the second fitting groove 205.

[0032] The storage groove 102 of the heat preservation box body 101 is the main placement space. The heat preservation cover 201 covers the heat preservation box body 101. The fitting convex block 202 is embedded in the storage groove 102, and the sealing block 204 is embedded in the sealing groove 104. Apply a certain downward pressure on the heat preservation cover 201 and the heat preservation box body 101 to make the first convex block 203 embedded in the first fitting groove 103 and the second convex block 105 embedded in the second fitting groove 205, so that the heat preservation box body 101 and the heat preservation cover 201 are initially docked. A sealing film is heat-sealed and attached to the surface of the groove body of the sealing groove 104 and the sealing block 204, which can improve the sealing effect of the sealing space formed by the sealing groove 104 and the sealing block 204.

[0033] The sealing structure 3 includes a limit block 301, a sealing soft ear 302, a threaded rod 303, a threaded cavity 304, a transmission rod 305, a pull ring 306, a groove 307, and a limit cavity 308. The limit block 301 is fixedly provided with a threaded rod 303, a sealing soft ear 302 is provided on one side of the limit block 301, and the sealing soft ear 302 is fixedly connected to the ear threaded cavity 304. The limit block 301 and the sealing soft ear 302 are fixedly connected through the threaded rod 303 and the threaded cavity 304. The center of one side of the limit block 301 is rotatably connected to the transmission rod 305, and one end of the transmission rod 305 is rotatably connected to the pull ring 306. A groove 307 is provided on one side of the limit block 301. A limit cavity 308 is formed between the limit block 301 and the sealing soft ear 302. The limit cavity 308 matches the limit ring 4, and the limit ring 4 is fixedly connected in the docking groove 106.

[0034] After the sealing groove 104 is docked with the sealing block 204, a certain space is left between the sealing block 204 and the bottom of the sealing groove 104. A certain negative pressure is generated between the sealing groove 104 and the sealing block 204 through a vacuum device, so that the insulation cover 201 and the insulation box body 101 are more tightly connected. Then the sealing soft ear 302 is first introduced into the docking groove 106. Since the outer ring of the sealing soft ear 302 is provided with a flexible material, it can be squeezed into the limiting ring 4 and introduced into the inner side of the limiting ring 4. Then the limiting block 301 is rotated to be fixedly connected with the sealing soft ear 302, and finally the limiting block 301 will be pressed against the limiting ring 4 to complete the docking seal. After all the docking grooves 106 are sealed, the sealing effect between the sealing groove 104 and the sealing block 204 can be greatly improved. When it is necessary to release the pressure to disassemble the insulation cover 201, the pull ring 306 is pulled out through the pull groove 307 to apply a certain pulling force. The limit block 301 together with the sealing soft ear 302 are pulled out of the docking groove 106, and then a certain pulling force is applied between the insulation cover 201 and the insulation box body 101, so that the sealing space between the sealing block 204 and the sealing groove 104 is expanded to be connected with the docking groove 106, and the sealed space will lose the negative pressure environment, and then the insulation cover 201 can be smoothly separated from the insulation box body 101. The design of the box body structure 1 and the box cover structure 2 of the utility model cooperates with the sealing structure 3 to greatly improve the sealing effect and the reuse effect of the insulation box. Increasing the connection tightness between the insulation cover 201 and the insulation box body 101 can reduce the use of auxiliary fixing devices. In order to improve the connection firmness, the conventional insulation cover 201 and the insulation box body 101 are connected by bonding or tape winding, which will reduce the reuse effect of the insulation cover 201 and the insulation box body 101.

[0035] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0036] In summary, by means of the above technical solution of the present utility model, the box body structure 1 is hermetically connected to the box cover structure 2. The box body structure 1 is connected to the sealing structure 3 through the limiting ring 4. The sealing structure 3 can improve the sealing effect after the negative pressure docking of the box body structure 1 and the box cover structure 2. The storage groove 102 of the heat preservation box body 101 is the main placement space. The heat preservation cover 201 covers the heat preservation box body 101. The fitting convex block 202 is embedded in the storage groove 102, and the sealing block 204 is embedded in the sealing groove 104. Apply a certain downward pressure on the heat preservation cover 201 and the heat preservation box body 101 to make its first convex block 203 embedded in the first fitting groove 103, and make the second convex block 105 embedded in the second fitting groove 205, so that the heat preservation box body 101 and the heat preservation cover 201 are initially docked. After the sealing groove 104 and the sealing block 204 are docked, there is a certain space between the sealing block 204 and the bottom of the sealing groove 104. A certain negative pressure is generated between the sealing groove 104 and the sealing block 204 by means of a vacuum pumping device, so that the heat preservation cover 201 and the heat preservation box body 101 are connected more tightly. Then the sealing soft ear 302 is first introduced into the docking groove 106. Since the outer ring of the sealing soft ear 302 is provided with a flexible material, it can be squeezed into the limiting ring 4 and introduced into the inner side of the limiting ring 4. Then rotate the limiting block 301 to fixedly connect it to the sealing soft ear 302. Finally, the limiting block 301 will abut against the limiting ring 4 to complete the docking seal. After all the docking grooves 106 are sealed, the sealing effect between the sealing groove 104 and the sealing block 204 can be greatly improved. When pressure relief is required to disassemble the heat preservation cover 201, the pull ring 306 is pulled out through the pull groove 307, and a certain pulling force is applied to pull out the limiting block 301 together with the sealing soft ear 302 from the docking groove 106. Then a certain pulling force is applied between the heat preservation cover 201 and the heat preservation box body 101, so that the sealing space between the sealing block 204 and the sealing groove 104 is expanded to communicate with the docking groove 106, and then the negative pressure environment of the sealing space will be lost. Then the heat preservation cover 201 and the heat preservation box body 101 can be separated smoothly. The design of the box body structure 1 and the box cover structure 2 of the present utility model in cooperation with the sealing structure 3 can greatly improve the sealing effect and the reuse effect of the heat preservation box. Improving the connection tightness between the heat preservation cover 201 and the heat preservation box body 101 can reduce the use of auxiliary fixing devices. In order to improve the connection firmness of the conventional heat preservation cover 201 and the heat preservation box body 101, bonding or tape winding is used, which will reduce the reuse effect of the heat preservation cover 201 and the heat preservation box body 101.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
