DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0036] The utility model provides a matching structure, which is arranged at both ends of the pieces to be spliced, and is used to realize the sequential splicing connection of multiple pieces to be spliced. It should be noted that in this embodiment, the pieces to be spliced ​​are aluminum profile corrugated plates 55, and the corrugated plates 55 are taken as an example for specific description below;

[0037] like Figure 1 and Figure 2 As shown, the matching structure in the utility model includes:

[0038] A first joint portion, provided at one end of the corrugated board 55, for splicing with the second joint portion;

[0039] The second joint portion is disposed at the other end of the corrugated board 55 and is used for splicing with the first joint portion.

[0040] Through this structural arrangement, the two ends of the corrugated board 55 can be overlapped with each other.

[0041] The matching structure provided by the utility model can realize the connection between the two by splicing when the corrugated board 55 is connected, by respectively arranging the first joint part and the second joint part spliced ​​with each other at both ends of the splicing piece. Since the joint parts are spliced, the splicing gap can be adjusted.

[0042] like Figure 1 As shown, further, the first joint portion is arranged at the right end of the corrugated board 55, including an upper clamping strip 1 and a lower overlap 2 arranged in parallel and spaced apart, the upper clamping strip 1 is inserted into the second joint portion, and the lower overlap 2 is overlapped on the second joint portion.

[0043] Specifically, the first joint portion has two splicing structures, namely, an upper clamping strip 1 and a lower overlap 2. The upper clamping strip 1 is clamped into the second joint portion, and the lower overlap 2 is overlapped on the second joint portion, thereby realizing the splicing structure between the first joint portion and the second joint portion. Since the clamping depth and overlap length of the upper clamping strip 1 and the lower overlap 2 can be adjusted, the splicing gap between the first joint portion and the second joint portion is adjustable.

[0044] Further, such as Figure 1 As shown, the length of the upper clamping strip 1 is greater than that of the lower overlap 2, and when the lower overlap 2 is overlapped in place, overlap gaps are left between the end of the upper clamping strip 1 and the bottom of the second joint part, and between the lower overlap 2 and the overlap surface of the second joint part.

[0045] Specifically, Figure 3 As shown, the overlap gap between the end of the upper clamping strip 1 and the bottom of the second joint portion is 0.6 mm, and the overlap gap between the lower overlap edge 2 and the overlap surface of the second joint portion is 0.3 mm.

[0046] Further, such as Figure 1 As shown, the lower overlap 2 is an S-shaped structure, including an extension portion 21 and an overlap portion 22, wherein the extension portion 21 is formed by vertically extending outward from the edge of the corrugated board 55, and the overlap portion 22 is L-shaped and connected to the end of the extension portion 21. For convenient and smooth overlap, the corners of the first overlap portion 22 and the second overlap portion 22 are both 90-degree arc transition structures.

[0047] Further, such as Figure 1 and Figure 2 As shown, the second joint portion is arranged at the left end of the corrugated board 55, including an upper clamping groove 3 and a lower lap platform 4 arranged in parallel and spaced apart. The upper clamping strip 1 is clamped into the upper clamping groove 3; and the lower lap edge 2 is overlapped on the lower lap platform 4.

[0048] Further, such as Figure 1 As shown, the upper slot 3 includes an upper slot wall 31 and a lower slot wall 32 , which are arranged in parallel and spaced apart, and are both formed by vertically extending outward from the edge of the corrugated board 55 ; the length of the upper slot wall 31 is less than that of the lower slot wall 32 .

[0049] Furthermore, the length of the lower platform 4 is greater than the length of the upper slot 3 , and the lower platform 4 is formed by vertically extending outward from the edge of the corrugated board 55 .

[0050] The matching structure provided by the utility model solves the problem that the splicing gap of the traditional aluminum profile splicing structure is difficult to adjust during the splicing process, and can effectively reduce the cumulative error at the same time. The overall splicing seam flatness after the aluminum profile is matched is higher than that of the traditional aluminum profile matching method. After installation, the upper side of the box body 6 has no edges and corners, and the splicing part is a mutually interlocking structure. When it is collided, it can evenly distribute the force, and has a higher deformation resistance than the original aluminum profile matching form.

[0051] The utility model provides a corrugated board 5, such as Figure 4 and Figure 5 As shown, it includes a board body and a matching structure arranged at both ends of the board body. It should be noted here that the matching structure arranged at both ends in the utility model refers to the two ends of the corrugated board 5 in the width direction, such as Figure 4 shown.

[0052] It should also be noted that Figure 4 and Figure 5 The structure diagram of an embodiment of the corrugated board 55 is shown in the figure, and the shape of the corrugated board 5 is selected and set according to the actual situation, and is also set according to the different positions of the box body 6. The utility model protects the matching structure of the two ends of the corrugated board 5, and the corrugated board 5 having the matching structure. The shape of the specific corrugated board 5 is not specifically limited.

[0053] Furthermore, in this embodiment, if Figure 1 and Figure 2 As shown, the plate body is made of aluminum profile and has a double-layer structure, including a protruding surface body 51 and a plane body 52 that are arranged at intervals, and a plurality of support rods 53 are arranged between the protruding surface body 51 and the plane body 52 to form a plurality of buffer cavities 54 between the protruding surface body 51 and the plane body 52.

[0054] In this embodiment, the protruding surface body 51 is a trapezoidal structure, and there are four support rods 53, which are respectively arranged at both ends and the middle of the protruding surface body 51. The two support rods 53 in the middle are inclined, and the two support rods 53 at both ends are vertically arranged.

[0055] like Figure 6-Figure 9 As shown, the corrugated plate 5 provided by the utility model is spliced ​​in a modular form. Since the splicing matching structure is used for continuous matching of the same aluminum profile, the two aluminum profile corrugated plates 5 rely on their own matching structure to perfectly splice at the matching gap, thereby improving the matching accuracy of the aluminum profile, and leaving a certain margin on the inner side of the assembly to facilitate the adjustment of the gap, and minimize the stacking error during the assembly process. The highly flat matching and double-layer bending structure ensure the strength of the matching, and ensure that effective protection is provided when the refrigerated transport box 6 is assembled. The appearance is more advanced, which is convenient for the printing of the appearance pattern of the box 6.

[0056] like Fig.10 As shown, the utility model provides a box body 6, including a box body and a shell covering the outside of the box body, the shell and the box body are connected by invisible rivets 7, and the shell is formed by splicing a plurality of corrugated boards 5 in sequence.

[0057] The box body 6 provided by the utility model is a new type of large-scale refrigerated transport box body 6, whose outer shell is made of aluminum profile corrugated plates 5 spliced ​​together. The self structure and splicing matching structure of the corrugated plates 5 are different from the traditional structure. The aluminum profile self structure is composed of a double-layer structure of a protruding surface body 51 and a plane body 52, with multiple sections of support rods 53 at a certain angle in the middle. The upper end of the plate is a 90° rounded bend transition. The aluminum profile manufacturing width tolerance is ±0.5mm. When assembled on the upper box body 6, invisible rivets 7 are used to fix it on the refrigerated transport box body 6, which ensures strength while having good airtightness and appearance.

[0058] In this embodiment, the aluminum profile corrugated board 5 assembly structure serves as the outer shell of the large refrigerated transport box 6, which can beautify the fresh-keeping equipment and protect the internal insulation layer of the fresh-keeping equipment. The outer shell of the mobile fruit and vegetable fresh-keeping equipment is now divided into multiple pieces of aluminum profile corrugated boards 5 for splicing and assembly. The required number of aluminum profile corrugated boards 5 can be determined according to the length of the mobile fresh-keeping equipment, and the required structure and dimensional accuracy of the aluminum profile corrugated boards 5 can be calculated according to different appearance requirements, accuracy requirements and strength requirements, and then assembled according to the required number of aluminum profile corrugated boards 5. It should be noted here that the outer shell is a large component spliced ​​as a whole, which is spliced ​​by single aluminum profile corrugated boards 5.

[0059] The matching structure of the aluminum profile corrugated plate 5 in the utility model is universal and is not limited to sports equipment for refrigerated transportation. Instead, it can be used as an outer shell splicing part of various types of boxes 6 by adjusting the structural dimensions of the aluminum profile corrugated plate 5. Therefore, this matching form of the aluminum profile corrugated plate 5 is universal and can be used across series and products.

[0060] During use, if Fig. 9 and Fig.10 As shown, the outer shell of the box body 6 is assembled by splicing similar corrugated plates 5, and the splicing is assembled by fitting the front and rear matching structures of the aluminum profile corrugated plates 5. In the process of assembling, invisible rivets 7 are used to fix the outer surface of the box body 6 to be assembled.

[0061] The invisible rivets 7 used when the aluminum profile corrugated board 5 is installed on the box body 6 can be set at the joint seam of the matching structure, so that the gap of each aluminum profile corrugated board 5 can be conveniently controlled, and the average installation error limit of each aluminum profile corrugated board 5 can be calculated according to the assembly requirements, and the cumulative error of the aluminum profile corrugated board 5 after assembly is ensured to be within the assembly requirement range. The structural strength is higher than that of the traditional corrugated board 5. The splicing structure of the corrugated board 5 of the present invention can be directly applied to the shell of the litchi refrigerated transport cabinet, beautify the product appearance, improve the anti-collision deformation ability of the box body 6 shell, and improve the competitiveness of similar products in the market.
