To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

A splice plate assembly 10 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1-9.

1-3, a splice plate assembly 10 according to an embodiment of the first aspect of the present invention comprises: the foaming plate comprises a first foaming plate 1, a second foaming plate 2, a first connecting piece 3 and a second connecting piece 4.

As shown in fig. 3-5, the first connecting member 3 includes a first foam catching portion 31 and a first matching portion 32, the first foam catching portion 31 is embedded in the first foam board 1, the second connecting member 4 includes a second foam catching portion 41 and a second matching portion 42, the second foam catching portion 41 is embedded in the second foam board 2, and the second matching portion 42 is in limit matching with the first matching portion 32 (i.e., at least limiting the first foam board 1 and the second foam board 2 to move relatively along one direction to generate separation). Here, it should be noted that the first bubble catching portion 31 and the second bubble catching portion 41 are both in a bubble catching structure, that is, a structure for improving the bonding reliability with the foaming material by increasing the contact area with the foaming material, and the specific shape of the bubble catching structure is not limited, and for example, the bubble catching structure may be configured as the bubble catching segment 5 described below or have a shape of a candied haw in cross section.

Therefore, since the first connecting member 3 has the first bubble catching portion 31, it is possible to improve the bonding strength of the first connecting member 3 with the first foam board 1, prevent the first connecting member 3 from being easily separated from the first foam board 1, and since the second connecting member 4 has the second bubble catching portion 41, so that the bonding strength of the second connector 4 and the second foaming sheet 2 can be improved, and the second connector 4 and the second foaming sheet 2 are prevented from being easily separated, and thus, when the first connecting piece 3 and the second connecting piece 4 are matched to limit the first foaming board 1 and the second foaming board 2, the reliability and effectiveness of the position limitation for the first foam board 1 and the second foam board 2 can be improved, moreover, the first foaming plate 1 and the second foaming plate 2 are limited through the first connecting piece 3 and the second connecting piece 4, and the connecting strength of the joint of the first foaming plate 1 and the second foaming plate 2 can be improved.

According to the splicing plate assembly 10 provided by the embodiment of the invention, the connecting piece with the foam grabbing part is pre-embedded in the foaming plate, so that the bonding strength and the bonding reliability between the foaming plates can be effectively improved. Moreover, because the foam boards are connected through the pre-embedded connecting pieces, the sealing tightness of the splicing part of the first foam board 1 and the second foam board 2 can be improved, and when the splicing board assembly 10 is used in refrigeration equipment as the box body 100, the problem of cold air leakage between the foam boards can be effectively solved.

In one embodiment of the present invention, as shown in fig. 3 and 4, the first mating portion 32 is an insertion portion and is formed by extending an end portion of the first bubble catching portion 31 in a direction away from the first bubble catching portion 31, as shown in fig. 3 and 5, the second mating portion 42 is a groove portion and is formed by recessing an end portion of the second bubble catching portion 41 in a direction toward a center of the second bubble catching portion 41, that is, the second mating portion 42 is formed in the second bubble catching portion 41, so that the structure of the second connecting member 4 is more compact, the distance between the first connecting member 3 and the second connecting member 4 is shorter, and the assembling compactness of the assembled plate assembly is better.

In one embodiment of the present invention, referring to fig. 4 and 5, at least one of the first bubble catching portion 31 and the second bubble catching portion 41 includes a bubble catching section 5, the bubble catching section 5 includes a body portion 51 and a plurality of rib portions 52, the plurality of rib portions 52 are spaced apart in a width direction of the body portion 51 (Y1-Y2 direction shown in fig. 6), a length direction of each rib portion 52 is the same as a length direction of the body portion 51 (X1-X2 direction shown in fig. 6), and a width direction of each rib portion 52 is perpendicular to a width direction of the body portion 51 (Y1-Y2 direction shown in fig. 6). Accordingly, both the main body 51 and the rib 52 can be in contact with the foamed material, thereby improving the bonding strength between the foam catching section 5 and the foamed material, that is, the foam catching effect. Further, referring to fig. 4, at least one of the first bubble catching portion 31 and the second bubble catching portion 41 includes two bubble catching segments 5 vertically connected, so that the bubble catching effect can be further improved, and the connection strength with the foaming material can be improved.

In some embodiments of the present invention, referring to fig. 3-5, the first engaging portion 32 has a first positioning structure 321 thereon, the second engaging portion 42 has a second positioning structure 421 thereon, and the first positioning structure 321 is in positioning engagement with the second positioning structure 421 (i.e. at least the first connecting element 3 and the second connecting element 4 are limited from moving relatively in one direction to be separated). Therefore, during assembly, through the positioning and matching of the first positioning structure 321 and the second positioning structure 421, whether the first matching part 32 and the second matching part 42 are assembled in place can be known, so that the assembly efficiency and the assembly reliability are improved. In addition, by providing the first positioning structure 321 and the second positioning structure 421, the convenience of pre-positioning the first connecting member 3 and the second connecting member 4 with the foaming mold 200 can be improved (see below for details).

For example, preferably, referring to fig. 3 to 5, the first positioning structure 321 may be configured as a positioning protrusion having a semicircular cross section, and the second positioning structure 421 may be configured as a positioning groove having a semicircular cross section, whereby the positioning protrusion and the positioning groove can be quickly positioned and disengaged to facilitate disassembly, for example, the first connecting member 3 and the second connecting member 4 can be disassembled in the left-right direction shown in fig. 3, although the present invention is not limited thereto, and the first connecting member 3 and the second connecting member 4 can also be disassembled in the direction perpendicular to the paper surface of fig. 3.

Preferably, as shown in fig. 2, 3 and 6, the first connecting member 3 is in an extrusion molding length condition and is embedded in the first edge 11 of the first foam board 1, the extrusion direction of the first connecting member 3 is the same as the length direction (X1-X2 direction shown in fig. 6) of the first edge 11 of the first foam board 1, the second connecting member 4 is in an extrusion molding length condition and is embedded in the second edge 21 of the second foam board 2, and the extrusion direction of the second connecting member 4 is the same as the length direction of the second edge 21 of the second foam board 2. In addition, in order to facilitate the assembly of the subsequent box 100, the other edges of the first foam board 1 may also be provided with the first connecting member 3 or the second connecting member 4, and meanwhile, the other edges of the second foam board 2 may also be provided with the first connecting member 3 or the second connecting member 4.

Therefore, the length of the first connecting piece 3 can be equal to or slightly smaller than that of the first edge 11, and the length of the second connecting piece 4 can be equal to or slightly smaller than that of the second edge 21, so that when the first connecting piece 3 and the second connecting piece 4 are used for connecting the first foaming board 1 and the second foaming board 2, the first edge 11 and the second edge 21 can be reliably matched with the second connecting piece 4 by virtue of the first connecting piece 3, and the matching strength of the joint of the first foaming board 1 and the second foaming board 2 is improved.

In some embodiments of the present invention, as shown in fig. 3, the first rim 11 and the second rim 21 are both L-shaped in cross-section and are joined in pairs. That is, the first rim 11 is formed with a first groove 111 that is recessed from one side surface in the thickness direction of the first foam board 1 toward the other side surface in the thickness direction of the first foam board 1 (from the left to the right direction as viewed in fig. 3) and is open at a side portion (i.e., a side surface in the center direction away from the first foam board 1, the lower side portion as viewed in fig. 3), and the first connector 3 is pre-buried at a bottom wall entity 112 of the first groove 111; the second rim 21 is formed with a second groove 211 that is recessed from one side surface in the thickness direction of the second foam board 2 toward the other side surface in the thickness direction of the second foam board 2 (from the top to the bottom direction as shown in fig. 3) and is open at the side (i.e., a side surface in the direction away from the center of the second foam board 2, as shown at the right side in fig. 3), and the second connection member 4 is pre-buried at a side wall entity 212 of the second groove 211; the first foaming board 1 and the second foaming board 2 are vertically arranged and the bottom wall entity 112 of the first groove 111 is spliced in the second groove 211. From this, the structure of foaming board sets up ingeniously, can realize the reliable seamless concatenation in first border 11 and second border 21, ensures that concatenation department comprises the contact of foaming material and foaming material to improve the heat preservation effect.

In some embodiments of the present invention, at least one of the first connecting member 3 and the second connecting member 4 is an extrusion-molded article, that is, at least one of the first connecting member 3 and the second connecting member 4 may be processed through an extrusion process, whereby the structure of the connecting member in each of the above-described embodiments can be simply and efficiently obtained.

Optionally, at least one of the first and

second connectors

3, 4 is an extruded sheet metal part. Thereby, the limit strength of the first connecting member 3 and the second connecting member 4 can be improved. Or alternatively at least one of the first connector 3 and the second connector 4 is an extruded plastic part. Thus, the production cost can be reduced.

Next, referring to fig. 7 to 9, a specific foaming process of the first and

second foam boards

1 and 2 according to an embodiment of the present invention will be described.

The foaming process of the first foamed sheet 1 is as follows: before foaming, as shown in fig. 8, the first connecting member 3 is mounted on the mold side plate 202 of the foaming mold 200 and is positioned, for example, when the first connecting member 3 has the first positioning structure 321, the first positioning structure 321 may be used to position the mold side plate 202. Next, the four side mold plates 202 and the lower mold plate 201, in which the first connecting member 3 is pre-positioned, are moved to enclose a chamber with an open top (as shown in fig. 7), and then a foaming material is injected into the chamber by using a foaming gun head, and the upper mold plate 203 is moved to the top of the sealed chamber, so that the chamber forms a sealed whole. After the foaming is completed, as shown in fig. 9, a first foamed plate 1 formed by foaming appears in the cavity, the first connecting member 3 pre-positioned on the mold side plate 202 is pre-embedded on the first foamed plate 1, and thereafter, the mold upper plate 203, the mold lower plate 201, and the mold side plate 202 of the foaming mold 200 can be removed.

The foaming process of the second foaming board 2 is substantially the same as the foaming process of the first foaming board 1, except that the positioning manner of the second connecting piece 4 and the mold side board 202 is slightly different due to the difference between the structure of the second connecting piece 4 and the structure of the first connecting piece 3, for example, the first positioning structure 321 of the first connecting piece 3 can be used for positioning with the mold side board 202, and then the positioning matching of the second connecting piece 4 and the mold side board 202 through the first connecting piece 3 is realized through the positioning matching of the second positioning structure 421 and the first positioning structure 321. In addition, the positioning of the first connecting member 3, the second connecting member 4 and the mold side plate 202 is not limited to this, and may be realized by other positioning methods, for example, by gluing.

In summary, according to the splice bar assembly 10 of the embodiment of the present invention, the first connecting member 3 is not easily separated from the first foam board 1 after foam molding by the first foam-catching portion 31, the first connecting member 3 is not easily separated from the mold side plate 202 before foam molding by the first positioning structure 321, the second connecting member 4 is not easily separated from the second foam board 2 after foam molding by the second foam-catching portion 41, and the second connecting member 4 is not easily separated from the mold side plate 202 before foam molding by the second positioning structure 421. In short, the anti-falling performance of the first connecting piece 3 and the second connecting piece 4 is improved before or after foaming, so that the first connecting piece 3 can be firmly embedded in the first foaming plate 1, the second connecting piece 4 can be firmly embedded in the second foaming plate 2, and the splicing reliability of the splice plate assembly 10 is improved.

According to the refrigeration equipment provided by the embodiment of the invention, the splicing plate assembly 10 of the embodiment of the first aspect is arranged, so that the cold air leakage problem is improved, and the overall performance of the refrigeration equipment is improved.

In summary, according to the refrigeration apparatus of the embodiment of the present invention, the assembly of the box body 100 is improved from the original "foaming of the foaming plate" by using an additional connecting member to assemble "the connecting member (i.e. the first connecting member 3 and the second connecting member 4) is pre-embedded when the foaming plate (i.e. the first foaming plate 1 and the second foaming plate 2) is foamed, so that the connecting member and the foaming plate form a whole to realize the direct splicing of the foaming plate.
