Modular Insulated Box

Abstract

This disclosure provides a modular insulated box, each unit comprising a crossbeam, side walls, top and bottom plates, a lower sealing plate for longitudinal gaps, and an upper sealing plate for longitudinal gaps. The crossbeam has a support portion with a notch. At least one of the lower sealing plates for longitudinal gaps has a downwardly bent sealing portion, allowing the bottom of the sealing portion to extend into the corresponding notch and sink relative to the crossbeam support portion within the notch. A pad is also included, its end extending into the notch and abutting against the crossbeam below the sealing portion of at least one of the plates, allowing the end of the pad to abut against the side of the crossbeam for sealing. According to this disclosure, the insulated box unit can absorb thermal expansion between the top and bottom plate units, and even when gaps exist between the end of the lower sealing plate for longitudinal gaps and the side of the crossbeam due to allowances for thermal expansion and installation errors, the insulation and sealing performance is still guaranteed.

Description

Technical Field

[0001] This application relates to the field of thin film processing, and more particularly to a modular insulated box. Background Technology

[0002] The top or bottom plate of the insulated box is composed of multiple top or bottom plate units arranged in a gap array. The gaps between adjacent top or bottom plate units are then sealed to achieve insulation within the box. To simplify the on-site installation process, prior patent application CN202420051631.5 proposed an upper and lower sealing plate structure installed between adjacent top and bottom plate units. During on-site installation, the lower sealing plate is first inserted into the gap through an opening above the gap between adjacent top and bottom plate units and connected and fixed to the top and bottom plate units to seal the lower opening of the gap. Then, insulation material and the upper sealing plate are inserted through an opening above the gap to seal the upper opening, greatly simplifying the entire installation process. However, in actual use of this structure, the intersection between the upper and lower sealing plates and the horizontally arranged crossbeams still presents a problem, directly affecting the insulation and heat insulation performance of the insulated box. Summary of the Invention

[0003] This disclosure provides a modular insulated box.

[0004] Specifically, this disclosure is achieved through the following technical solution:

[0005] This disclosure provides a modular insulated box, which is composed of multiple insulated box units assembled sequentially. Each insulated box unit includes:

[0006] Crossbeams are provided at both longitudinal ends of the insulation box unit;

[0007] Side walls, a pair of side walls are respectively set on both sides of the insulated box unit;

[0008] The top and bottom plates are provided with multiple top and bottom plate units, which are arranged in a gap array along the transverse direction and supported on the crossbeam at both ends in the longitudinal direction, so that a longitudinal gap is formed between adjacent top and bottom plate units.

[0009] The lower sealing plate of the longitudinal gap is provided with a first snap-fit ​​part and a sealing part, so as to be suitable for the lower sealing plate of the longitudinal gap to be inserted into the longitudinal gap from the upper opening of the longitudinal gap and connected to the top and bottom plate unit, thereby using the sealing part to seal the lower opening of the longitudinal gap;

[0010] The upper sealing plate of the longitudinal gap is provided with a second snap-fit ​​part to be adapted to connect with the top and bottom plate units, thereby sealing the upper opening of the longitudinal gap;

[0011] The support portion of the crossbeam has a notch, and at least one of the sealing portions of all the longitudinal gap lower sealing plates in the transverse direction has a downward bending shape, so that the bottom of the sealing portion of the at least one can extend into the corresponding notch and sink relative to the support portion of the crossbeam within the notch.

[0012] It also includes a pad, the end of which extends into the notch and is positioned close to the crossbeam below the sealing portion of the at least one of them, so that the end of the pad can abut against the side of the crossbeam for sealing.

[0013] According to various embodiments of this disclosure, the downward bending shape formed by the sealing portion of at least one longitudinal gap lower sealing plate in the transverse direction allows the insulation box unit to absorb the thermal expansion allowance and installation error between the top and bottom plate units in the transverse direction, since the downward bending shape can shrink or expand to a certain extent in the transverse direction; by forming a notch on the support portion on the crossbeam, the notch corresponds to the position of at least one longitudinal gap lower sealing plate in the transverse direction, since the sealing portion of the longitudinal gap lower sealing plate can be bent downward and extend into the notch, and at the same time the end of the pad extends into the notch, the notch provides the downward bending space of the sealing portion and the extension space of the end of the pad, and the pad end abuts against the side of the crossbeam to seal, so that the thermal insulation and sealing performance can still be guaranteed even if there is a gap between the end of the longitudinal gap lower sealing plate and the side of the crossbeam due to thermal expansion allowance and installation error.

[0014] In some embodiments, the pad has two sides and a support portion between them. The two sides overlap the support portions of the crossbeams on both sides of the notch. The support portion is shaped to match the sealing portion of the lower sealing plate of the longitudinal gap, thereby pressing the bottom of the sealing portion to seal it. It can also move and deform with the lower sealing plate of the longitudinal gap under the pressed state. The lateral dimension of the notch is larger than the support portion. The pad overlaps the support portion on the support portion of the crossbeam, providing upward support. The shape matching of the support portion with the sealing portion of the lower sealing plate of the longitudinal gap ensures that the upward force of the pad is perfectly aligned with the bottom contour of the sealing portion of the lower sealing plate of the longitudinal gap, guaranteeing a tight seal between the pad and the sealing portion.

[0015] In some embodiments, an elastic sealing strip is further provided between the pad and the sealing portion of the lower sealing plate of the longitudinal gap, so as to be suitable for the sealing strip to be pressed between the pad and the sealing portion in an elastic deformation state. By providing an elastic sealing strip, the gap between the pad and the sealing portion can be filled, further ensuring the sealing of the gap between the pad and the sealing portion.

[0016] In some embodiments, the system further includes uprights disposed at the four corners of the insulation box unit and located between the crossbeam and the sidewall, so as to allow the support portion of the crossbeam, the top of the sidewall, and the top of the uprights to together form a continuous top surface. By providing a sealing strip on the continuous top surface, the sealing strip can be continuously supported by the continuous top surface, thereby enabling continuous sealing of the gap between the continuous top surface and the top and bottom plate units.

[0017] In some embodiments, the top and bottom plates include a top plate, the crossbeam includes an upper beam, and the top plates of adjacent insulation box units overlap the upper beam, thereby forming a transverse gap between the top plates of adjacent insulation box units. The crossbeam also includes a transverse gap sealing plate with a third snap-fit ​​portion adapted to connect with the top plate unit with a reserved thermal expansion allowance, thereby sealing the upper opening of the transverse gap. The longitudinal side of the transverse gap sealing plate has a bend, and the longitudinal end of the longitudinal gap sealing plate has a bevel, adapted to match and fit the bend when the transverse gap sealing plate and the longitudinal gap sealing plate intersect. This configuration allows the transverse gap sealing plate to be easily inserted from above the transverse gap between adjacent insulation box units, thus covering the upper opening of the transverse gap. The operation is simple, and the sealing performance is good. Simultaneously, the bevel structure at the longitudinal end of the longitudinal gap sealing plate can be guided to be inserted below the side wall of the transverse gap sealing plate, thereby ensuring a tight connection between the longitudinal gap sealing plate and the transverse gap sealing plate.

[0018] In some embodiments, the top and bottom plates include a bottom plate, the crossbeam includes a lower beam, and the bottom plates of adjacent insulation box units overlap the support portions on both longitudinal sides of the lower beam, thereby forming a transverse gap between the bottom plates of adjacent insulation box units and the lower beam side. The system also includes a side sealing plate with a fourth snap-fit ​​portion adapted to connect with the bottom plate unit in a manner that allows for thermal expansion, thereby sealing the upper opening of the transverse gap. The side sealing plate includes: a horizontal portion for overlapping the top of the bottom plate; a vertical portion for abutting against the longitudinal side of the lower beam; and a bend portion for elastically abutting against the longitudinal side of the bottom plate unit. The horizontal portion, vertical portion, and bend portion are connected sequentially to seal the upper opening of the transverse gap. Since the horizontal position of the base plate unit is lower than the top of the lower beam, support parts are set on both sides of the longitudinal direction of the lower beam, so that the base plate unit overlapping the support parts and the lower beam form a transverse gap. The side sealing plate can be used to press and seal the transverse gap. At the same time, the horizontal part covers the opening above the transverse gap, the vertical part presses against the side of the lower beam, and the elastic force of the bend is used to press against the base plate unit to ensure the sealing.

[0019] In some embodiments, the support extends out of the side of the beam to form a notch. By placing the support on the side of the beam, the horizontal height of the bottom surface of the top and bottom plate units can be reduced, thereby improving the installation height flexibility of the top and bottom plate units.

[0020] In some embodiments, a secondary longitudinal gap is formed between the sidewall and the top and bottom plates, and the secondary longitudinal gap also includes an upper sealing plate with a fifth snap-fit ​​portion adapted to connect with the top and bottom plate unit and the side plate respectively, with a reserved thermal expansion allowance, thereby sealing the upper opening of the secondary longitudinal gap. The upper sealing plate is inserted into the upper opening of the secondary longitudinal gap between the sidewall and the top and bottom plates, achieving efficient and quick sealing of the secondary longitudinal gap opening.

[0021] In some embodiments, a vertical gap is formed between the side walls of adjacent insulated box units, and a vertical gap sealing plate is further included, which is provided with a sixth snap-fit ​​portion to be adapted to connect with the side plate in a manner that allows for thermal expansion, thereby sealing the lateral opening of the vertical gap. The vertical gap opening is efficiently and quickly sealed by inserting the vertical gap sealing plate from the outer opening of the vertical gap between adjacent side walls.

[0022] In some embodiments, adjacent insulated box units have a dimensional difference in the lateral direction, thereby creating a step difference between the sidewalls of adjacent insulated box units on the same side. The modular insulated box further includes: a first sealing plate, configured as an "L" shape, for sealing the step difference from the side; and a second sealing plate for sealing the step difference from the top surface. By setting the first and second sealing plates, the step difference can be sealed from the side and top surfaces respectively, ensuring the insulation and sealing performance between insulated box units with different lateral dimensions.

[0052] This 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 this disclosure, and are not intended to imply any limitation on the scope of this disclosure.

Other explicit and implicit definitions may also be included below.

[0054] Specific numerical values ​​or ranges may be referred to in the following description. It should be understood that these values ​​and ranges are merely exemplary and may be helpful in putting the ideas of this disclosure into practice. However, the description of these examples is not intended to limit the scope of this disclosure in any way. These values ​​or ranges may be set differently depending on the specific application scenario and requirements.

[0055] As mentioned above, the installation process of existing insulated boxes is cumbersome, and the connection problem between the longitudinal gap upper sealing plate and the longitudinal gap lower sealing plate used to seal the gaps and the transverse arrangement structure has not yet been solved. The modular insulated box proposed in the embodiments of this disclosure at least partially solves the above problems. The following will refer to Figures 1 to 11 This describes the structure and working principle of a modular insulated box according to exemplary embodiments of the present disclosure. For example... Figure 1 and 3As shown, the modular insulated box described herein generally includes multiple insulated box units 01, which are arranged in a longitudinal array to form an insulated box. Adjacent insulated box units 01 share a set of upper beam 11 and lower beam 12.

[0056] The following description uses an insulated box unit 01 as an example to illustrate its specific structure and operation. Figure 1 and 3 As shown, the insulation box unit 01 has an overall frame structure. The frame structure is composed of an upper beam 11, a lower beam 12, a side wall 20, and a column 71. The top plate unit 31 and the bottom plate unit 32 are stably supported on the frame. The gaps are then sealed with sealing plates. The whole installation process is convenient and quick.

[0057] Specifically, such as Figure 1-7 As shown, the skeleton is generally cubic in shape, with four pillars 71 positioned at the four corners of the cube. An upper beam 11 and a lower beam 12 are positioned between two horizontal pillars 71, extending laterally and fixedly connected at both ends to the two pillars 71. The upper beam 11 and lower beam 12 are arranged vertically, forming an elongated opening between them for the membrane to pass through. For example, the upper beam 11 and lower beam 12 can be integrally formed or formed from multiple interconnected segments.

[0058] A side wall 20 is provided between the two longitudinal columns 71. The side wall 20 provides support and seals off the transverse ends of the frame. For example, the side wall 20 can be fixedly connected to the two longitudinal columns 71 at their respective ends, or it can be supported by the bottom support structure.

[0059] The top and bottom plates cover the top and bottom of the insulation box unit 01, respectively, thus forming a closed space together with a pair of side walls 20. To ensure the insulation and sealing of the closed space, the gaps formed during installation need to be sealed. Specifically, for ease of processing and installation, the top plate is made of multiple top plate units 31. Generally, the dimensions of each top plate unit 31 are set to be exactly the same to reduce the difficulty of on-site installation. Alternatively, the dimensions of each top plate unit 31 can be designed to be different, as long as the top plate unit 31 can overlap the support part 121 of the upper beam 11 or the lower beam 12, and all the top plate units 31 can cover the top of the insulation box in the horizontal direction.

[0060] In one embodiment, such as Figure 8As shown, each top plate unit 31 includes an upper plate 311 and a lower plate 312. The upper plate 311 is configured with a first horizontal plate 313 and first vertical plates 314 surrounding the first horizontal plate 313. The lower plate 312 is configured with a second horizontal plate 315 and second vertical plates 316 surrounding the second horizontal plate 315, so that both the upper plate 311 and the lower plate 312 are formed into a box-shaped structure, thereby stacking on each other to form a cavity for filling with insulation material. In another embodiment, each bottom plate unit 32 may also have the same structure as the top plate unit 31, which will not be described in detail here.

[0061] Each insulated box unit 01 in this embodiment of the present disclosure has gaps, and gaps also exist between adjacent insulated box units 01. Specifically, longitudinal gaps 41 are formed between horizontally adjacent top plate units 31 and horizontally adjacent bottom plate units 32; secondary longitudinal gaps are formed between the outermost top plate unit 31 and the side wall 20, and between the outermost bottom plate unit 32 and the side wall 20; transverse gaps 42 are formed between the top plate units 31 of adjacent insulated box units 01 and between the bottom plate unit 32 and the lower beam 12; and vertical gaps 43 are formed between the side walls 20 of adjacent insulated box units 01.

[0062] The lower sealing plate 51 is used to seal the opening below the longitudinal gap 41, and the upper sealing plate 52 is used to seal the opening above the longitudinal gap 41. In one embodiment, such as Figure 10 As shown in (a), the longitudinal gap lower sealing plate 51 generally includes a pair of vertically extending vertical walls. The top of each vertical wall has a first locking portion 511 that is spaced apart from each other, and the bottom of each vertical wall has a pair of inclined walls that extend at an angle. The first locking portion 511 has a downward-facing hook structure, which ensures that it hooks downwards onto the upward-facing open end of the second vertical plate 316. In other embodiments, the first locking portion 511 can also be an overlapping structure facing both sides. As long as it can overlap the upward-facing open end of the second vertical plate 316, the second vertical plate 316 can support the longitudinal gap lower sealing plate 51 upwards.

[0063] In this design, a pair of inclined, extending sloped walls intersect to form the bottom apex of the lower sealing plate 51 of the longitudinal gap, thereby forming the sealing portion 512 of the lower sealing plate 51. Specifically, the use of a pair of inclined, extending sloped walls allows for the absorption of thermal expansion of the top plate unit 31 through elastic deformation during normal operation, while also facilitating the movement of the lower sealing plate 51 of the longitudinal gap to the installation position within the gap. Those skilled in the art will understand that any structure capable of absorbing thermal expansion can serve as the sealing portion 512 in this embodiment of the present disclosure; for example, such as... Figure 9 As shown, the sealing part 512 can also be arc-shaped, flat, wavy, etc.

[0064] It should be noted that, in this embodiment, only at least one of the longitudinal gap lower sealing plates 51 in the lateral direction is required to have a sealing portion 512 capable of extending downward into the notch 13, thereby utilizing the lateral deformation capability of the sealing portion 512 to adjust the installation error between the top plate units 31 in the lateral direction. That is, for the other longitudinal gap lower sealing plates 51 in the lateral direction, since they do not need to extend into the notch 13 (therefore, the corresponding notch 13 can be omitted), the sealing portion 512 can be configured as follows: Figure 9 (a) shows the flat bottom form, or as shown in Figure 9 (b) shows an upwardly sloping extension, or as shown in Figure 9 As shown in (c), the upward arched form of the sealing part 512 still has the ability to deform in the lateral direction, but the effect is slightly reduced.

[0065] In one embodiment, such as Figure 10 As shown in (b), the longitudinal gap upper sealing plate 52 includes a pair of vertically extending claws, and a cover is provided on the top of the pair of claws. The pair of claws are used to form a second snap-fit ​​portion 521. When the pair of claws are in a fully released elastic deformation state, they are inclined and extend away from each other from top to bottom. Thus, during the insertion into the longitudinal gap 41, they are squeezed and elastically deformed by the top plate unit 31 to ensure the sealing performance between the longitudinal gap upper sealing plate 52 and the top plate unit 31.

[0066] like Figure 4 and 5 As shown, the top surface of the upper beam 11 serves as a support 121, supporting the top plate unit 31. Due to thermal expansion allowance and processing / installation errors, a gap needs to be reserved between the end of the lower sealing plate 51 and the upper beam 11. Airflow will pass through this gap between the enclosed space and the external environment, thus affecting the thermal insulation performance within the enclosed space. To solve this problem, in this embodiment, a pad 61 is provided at the notch 13. The end of the pad 61 is pressed against the side of the upper beam 11, and the top of the pad 61 is attached to the bottom surface of the sealing portion 512 of the lower sealing plate 51, thereby sealing and blocking the airflow.

[0067] In one embodiment, such as Figure 10 As shown in (d), the pad 61 is provided with two side sections 611 and a support section 612 located between the two side sections 611. The two side sections 611 overlap the top surface of the upper beam 11 on both sides of the notch 13. The support section 612 is formed to be bent downward and extend into the notch 13, and the shape of the support section 612 matches the sealing section 512 of the lower sealing plate 51 of the longitudinal gap. Since the support section 612 has elastic deformation capability, it can always press the support section 612 against the surface of the sealing section 512 of the lower sealing plate 51 of the longitudinal gap, ensuring the gap is sealed.

[0068] In another embodiment, the lateral dimension of the notch 13 is set to be at least larger than the lateral dimension of the support portion 612, so that the support portion 612 can still move laterally within the notch 13, thereby improving the ability to absorb installation errors in the lateral direction.

[0069] The notch 13 and the longitudinal gap lower sealing plate 51 structure of this disclosure embodiment are also applicable to bottom plate sealing. For example... Figure 6 As shown, the difference is that, in order to make the horizontal height of the bottom plate unit 32 lower and thus release a larger enclosed space, a support part 121 is formed by horizontally extending on the side of the lower beam 12. In this case, the structure of the upper longitudinal gap sealing plate 52 and the lower longitudinal gap sealing plate 51 is the same as that at the top plate unit 31, and the sealing method between the sealing part 512 of the lower longitudinal gap sealing plate 51 and the pad 61 is also the same as that at the top plate unit 31.

[0070] The upper opening of the transverse gap 42 formed between the top plate units 31 of adjacent insulation box units 01 is sealed using a transverse gap sealing plate 54. The transverse gap sealing plate 54 is provided with a third snap-fit ​​part for snapping onto the top plate units 31 on both sides. As mentioned above, since the positional relationship between the bottom plate unit 32 and the lower beam 12 is different, the transverse gap 42 between the side of the bottom plate unit 32 and the lower beam 12 is sealed using a side sealing plate 53. Figure 10 As shown in (c), the side sealing plate 53 includes a horizontal part 531, a vertical part 532 and a back bend part 533. The horizontal part 531 is used to overlap the top of the base plate unit 32, the vertical part 532 is used to abut against the side of the lower beam 12, and the back bend part 533 is used to elastically abut against the first vertical wall of the base plate unit 32, thereby forming a fourth snap-fit ​​part, which can absorb the installation error and thermal expansion allowance of the base plate unit 32 in the longitudinal direction.

[0071] The longitudinal gap 41 between the side wall 20 and the top plate unit 31 is sealed using a longitudinal gap sealing plate 55. The longitudinal gap sealing plate 55 is provided with a fifth snap-fit ​​part, which can connect between the side wall 20 and the top plate unit 31, and can absorb lateral installation errors and thermal expansion allowances. As mentioned above, since there is a difference in the positional relationship between the bottom plate unit 32 and the side wall 20, a longitudinal gap sealing plate 55 with a structure similar to that of the side sealing plate 53 is used for sealing.

[0072] The vertical gap 43 formed between the side walls 20 of adjacent insulation box units 01 is sealed using vertical gap sealing plate 56, such as... Figure 10 As shown in (e), the vertical gap sealing plate 56 is provided with a sixth snap-fit ​​part for installation at the vertical gap 43 between adjacent side walls 20, and can absorb the installation error and thermal expansion allowance of the side wall 20 in the longitudinal direction.

[0073] At the intersection of the transverse gap 42 and the longitudinal gap 41, a sealing problem needs to be addressed. In this embodiment, the longitudinal side of the upper sealing plate 54 of the transverse gap is bent, and the longitudinal end of the upper sealing plate 52 of the longitudinal gap is beveled, so that the bend and bevel at the intersection of the upper sealing plate 54 of the transverse gap and the upper sealing plate 52 of the longitudinal gap match and fit together, thereby improving the local sealing effect.

[0074] In one embodiment, the top surface of the column 71, the top surface of the side wall 20, and the top surface of the upper beam 11 together form a connecting surface. A sealing strip 62 is provided on the connecting surface. Since the top plate unit 31 is supported by this connecting surface, the sealing strip 62 is continuously clamped, ensuring a tight seal between the top plate unit 31 and the connecting surface. In another embodiment, the sealing strip 62 can extend between the pad 61 and the sealing portion 512 of the lower sealing plate 51 of the longitudinal gap, further improving the sealing performance between the pad 61 and the sealing portion 512 of the lower sealing plate 51 of the longitudinal gap.

[0075] In one embodiment, adjacent insulated box units 01 may have different dimensions in the lateral direction, such as... Figure 11 As shown, a step difference is formed between the side walls 20 on the same side of adjacent insulation box units 01. A first sealing plate 72 and a second sealing plate 73 are provided. The first sealing plate 72 is set in an "L" shape so that the step difference can be blocked from the side. The second sealing plate 73 blocks the step difference from the top surface.
