[0035] The present disclosure will now be discussed with reference to several embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the present disclosure, rather than implying any limitation on the scope of the present disclosure.

[0036] As used herein, the term "including" and its variations are to be interpreted as open-ended terms meaning "including but not limited to". The term "based on" is to be interpreted as "based at least in part on". The terms "embodiment" and "one embodiment" are to be interpreted as "at least one embodiment". The term "another embodiment" is to be interpreted as "at least one other embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0037] In the following description, some specific numerical values ​​or numerical ranges may be involved. It should be understood that these numerical values ​​and numerical ranges are merely exemplary, which may be helpful in putting the idea of ​​the present disclosure into practice. However, the description of these examples is not intended to limit the scope of the present disclosure in any way. According to specific application scenarios and requirements, these numerical values ​​or numerical ranges can be set separately.

[0038] As described above, in the prior art, due to the complex connection structure between the lower sealing plate 30 and the top and bottom plate units, during the splicing process of the top and bottom plates of the insulated box, a worker is required to hold up the lower sealing plate 30 below the gap, and another worker is required to insert the upper sealing plate 40 above the gap, and then tighten the upper sealing plate 40 and the lower sealing plate 30 together through bolts. The whole process requires two people to work together to complete the splicing process, which is cumbersome, time-consuming and labor-intensive. The splicing structure of the top and bottom plates of the insulated box proposed in the embodiments of the present disclosure at least partially solves the above-mentioned problem. Figures 1 to 8 The top and bottom panels of the incubator according to the exemplary embodiment of the present disclosure are described in detail. The top panel of the incubator is used as an example to explain the specific embodiments of the present disclosure in detail. Those skilled in the art can understand that the embodiments of the present disclosure are also applicable to the bottom panel of the incubator. Figure 1-2 As shown, in general, the top plate splicing structure of the insulated box described herein includes a plurality of top plate units, a lower sealing plate 30 and an upper sealing plate 40, wherein the structures of the plurality of top plate units are the same and are in a gap array, the lower sealing plate 30 and the upper sealing plate 40 are respectively used to seal each gap from the top and the bottom, and at the same time, the upper plate 10 is only in direct contact with the upper sealing plate 40, and the lower plate 20 is only in direct contact with the lower sealing plate 30, and the two groups of structures in direct contact are designed with insulation sealing strips, countersunk holes, insulation pads, etc. to reduce heat transfer, ensuring that no matter which side of the upper or lower side is in contact with the high-temperature air, the heat will not be directly conducted to the other side along the structure, thereby improving the insulation effect.

[0039] In order to make the top plate unit have a heat-insulating effect, the top plate unit is generally configured to have a cavity, and the cavity is filled with heat-insulating material for heat-insulating. In one embodiment, each top plate unit includes an upper plate 10 and a lower plate 20, the upper plate 10 is configured to have a first horizontal plate and a first vertical plate around the first horizontal plate, and the lower plate 20 is configured to have a second horizontal plate and a second vertical plate 21 located around the second horizontal plate, so that the upper plate 10 and the lower plate 20 are both formed into a box-shaped structure, so that they are stacked on each other to form a cavity for filling with heat-insulating material. Exemplarily, the first vertical plate and the first horizontal plate can be integrally bent and formed, or can be connected and formed by welding or the like, and the second vertical plate 21 and the second horizontal plate can be integrally bent and formed, or can be connected and formed by welding or the like.

[0040] In one embodiment, in order to ensure a stable stacking connection between the upper plate 10 and the lower plate 20 and to form a structure for connection with the lower sealing plate 30, the relative spacing between the first vertical plates and the relative spacing between the second vertical plates 21 are designed so that the spacing between a pair of opposite second vertical plates 21 is greater than that between a pair of opposite first vertical plates. When the upper plate 10 and the lower plate 20 are stacked and snapped together, the surrounding second vertical plates 21 are located on the outside of the first vertical plates, so that the second vertical plates 21 form an open end facing upward, and the overlapping parts of the first vertical plates and the second vertical plates 21 are further connected by screws or rivets 22.

[0041] In another embodiment, in order to reduce the contact area between the upper plate 10 and the lower plate 20, thereby reducing heat transfer, a countersunk structure is used between the first vertical plate and the second vertical plate 21. The countersunk structure is connected by rivets 22, and the countersunk contact part can also be insulated with an insulation pad.

[0042] The lower sealing plate 30 is used to connect with the top plate unit to seal the gap at the bottom. Figure 3-5 As described above, the lower sealing plate 30 as a whole includes a pair of vertically extending vertical walls 31, the top of the vertical walls 31 is provided with a bend portion 33 that is away from each other, and the bottom of the vertical walls 31 is provided with a pair of inclined walls 32 that extend obliquely. Among them, the bend portion 33 constitutes a first clamping portion, and since the bend portion 33 has a downward hook structure, it can be ensured that the bend portion 33 is hooked downward on the upward open end of the second vertical plate 21. In other embodiments, the first clamping portion can also be an overlap structure facing both sides, as long as it can overlap on the upward open end of the second vertical plate 21, the second vertical plate 21 can support the lower sealing plate 30 upward.

[0043] In one embodiment, a pair of inclined walls 32 extending obliquely intersect to form the bottom vertex of the lower sealing plate 30, thereby forming a blocking portion of the lower sealing plate 30. Specifically, a pair of inclined walls 32 extending obliquely can absorb the thermal expansion of the top plate unit through controlled deformation during normal operation, and it is also beneficial for the lower sealing plate 30 to move to the installation position in the gap. Those skilled in the art will understand that any structure that can absorb thermal expansion can be used as the blocking portion of the embodiment of the present disclosure. For example, the blocking portion can also be in the shape of an arc, a plane, a wave, etc.

[0044] In one embodiment, during the manufacturing process, a pair of vertically extending vertical walls 31 are maintained in a completely elastically released state, extending in an inclined direction from top to bottom toward each other. After the lower sealing plate 30 is placed in the gap, under the squeezing action of the upper plate 10 on both sides of the gap, the pair of vertical walls 31 are compressed to a certain extent, thereby generating an elastic deformation rebound force, further ensuring the sealing between the lower sealing plate 30 and the top plate unit, and also facilitating the stacking of multiple lower sealing plates 30, which is beneficial to saving space during transportation.

[0045] The upper sealing plate 40 is used to connect with the top plate unit to seal the gap at the top. Figure 6-8 As shown, the upper sealing plate 40 includes a pair of vertical claws 43 extending vertically, and a cover portion 41 is arranged on the top of the pair of vertical claws 43, wherein the pair of vertical claws 43 are used to form a second clamping portion, and the pair of vertical claws 43 are in an inclined extension away from each other from top to bottom when the elastic deformation is fully released, so that during the process of being inserted into the gap, they are elastically deformed by being squeezed by the top plate unit, thereby ensuring the sealing between the upper sealing plate 40 and the top plate unit.

[0046] In one embodiment, a second bending portion 44 close to each other is formed at the bottom of the pair of vertical claws 43. The second bending portion 44 can guide the vertical claws 43 to slide into the gap when the upper sealing plate 40 is installed, and can also be used to clamp the thermal insulation material, so that when the pair of vertical claws 43 of the upper sealing plate 40 are inserted into the gap, the thermal insulation material can be firmly placed in the gap at the same time.

[0047] In one embodiment, the cover 41 is used to cover the opening above the gap, and the cover 41 is directly overlapped above the first horizontal plate of the upper plate 10, so as to completely cover and seal the opening above the gap. In another embodiment, a heat insulation sealing strip 50 is arranged between the cover 41 and the first horizontal plate, and the heat insulation sealing strip 50 is squeezed and deformed by the upper sealing plate 40 itself under its own gravity, thereby improving the sealing effect.

[0048] In one embodiment, a first bending portion 42 is formed on both sides of the cover portion 41, and the first bending portion 42 wraps around the thermal insulation sealing strip 50. By setting the first bending portion 42, a continuous transition surface is formed between the cover portion 41 of the upper sealing plate 40 and the first horizontal plate of the upper plate 10 to avoid scratches during use.

[0049] In one embodiment, a heat insulating sealing strip 50 is embedded between the bend portion 33 and the first vertical plate, and when the lower sealing plate 30 is hooked at the open end of the second vertical plate 21 , the gap between the bend portion 33 and the first vertical plate is sealed by the heat insulating sealing strip 50 .

[0050] The specific steps of using the insulation box top plate splicing structure of the embodiment disclosed in the present invention are as follows:

[0051] S1, stacking the upper plate 10 and the lower plate 20 and connecting them with rivets 22 to form a top plate unit;

[0052] S2, arranging a plurality of top plate units in a gap array, and adjusting the gap between the top plate units to a preset value using a tool;

[0053] S3, fill the lower sealing plate 30 with insulation material (it is also possible not to temporarily fill the lower sealing plate 30 with insulation material, but to clamp the insulation material together with the upper sealing plate when installing it later), insert the lower sealing plate 30 from the upper opening of the gap, and slide downward in the gap until the bent portion is hooked and fixedly connected with the second vertical plate 21 of the lower plate 20;

[0054] S4, fill the upper sealing plate 40 with insulation material (the insulation material can be pre-packed with fiberglass cloth for easy installation), insert the upper sealing plate 40 into the gap, so that the cover 41 covers the first horizontal plate of the upper plate 10, thereby completing the installation process.
