Description

Technical Field

[0001] The utility model relates to the technical field of clean panels, in particular to a corner connector for melamine resin panels and a clean panel assembly. Background Art

[0002] During the construction process, adjacent melamine resin panels need to be transitioned through aluminum profiles at the 90° corners, and the corner aluminum profiles are required to clamp the panels to ensure verticality.

[0003] In the related technical solutions, the stop positioning is achieved only by plugging the plug-in positioning piece at the corner connector into the positioning groove at the side surface of the clean board, which easily causes the plug-in positioning piece to be deformed by force and the verticality of the adjacent clean boards to be poor.

[0004] In addition, after the adjacent clean panels are connected by the corner connector, the board gap between the clean panel and the corner connector needs to be filled with resin glue for sealing. The board gap is too small to be filled with much resin glue, and the resin glue easily bulges out of the clean panel and easily escapes everywhere. Utility Model Content

[0005] The utility model provides a corner connector for a melamine resin board and a clean board assembly, which can solve at least one of the above technical problems.

[0006] In order to solve the above-mentioned technical problems, one or more embodiments of the utility model provide a corner connector and a clean panel assembly for melamine resin panels, comprising a first straight panel and a second straight panel vertically connected to each other in an angular shape, a concave right-angle notch is formed at the junction of the first straight panel and the second straight panel, the ends of the first straight panel and the second straight panel away from each other are connected to each other through an arc panel assembly, the arc panel assembly comprises a main arc panel and auxiliary arc panels at both ends along the curvature direction of the main arc panel, the end of the auxiliary arc panel away from the main arc panel is connected to the adjacent first straight panel or the second straight panel; the arc panel assembly, the first straight panel and the second straight panel are combined to form an inner cavity, the inner arc surface of the main arc panel faces the inner cavity, the outer arc surface of the auxiliary arc panel faces the inner cavity, the auxiliary arc panel and the adjacent first straight panel or the second straight panel are combined to form a glue-containing groove, and the auxiliary arc panel is protruding from the first straight panel or the second straight panel; the side of the first straight panel or the second straight panel facing away from the inner cavity is provided with a plug-in positioning member.

[0007] One or more embodiments of the utility model further provide a clean board assembly, comprising at least two clean boards perpendicular to each other, the ends of the clean boards having keels, adjacent clean boards being connected by corner connectors through the above-mentioned melamine resin boards, and the plug-in positioning pieces of the corner connectors being plugged into the keels.

[0008] Furthermore, the first straight plate and the second straight plate respectively stop against the end surfaces of the two clean plates, and the glue containing groove and the right-angle notch are filled with sealant to achieve sealing of the corner connector and the clean plate.

[0009] The beneficial effects of one or more of the above technical solutions are:

[0010] In this solution, a first straight plate and a second straight plate that are perpendicular to each other are used. The first straight plate and the second straight plate can respectively fit and stop adjacent clean plates, so that the two connected clean plates remain in a vertical state due to the coordination with the positions of the first straight plate and the second straight plate; this setting method, combined with the plug-in positioning pieces at the first straight plate and the second straight plate, can improve the verticality of the two straight plates at the corners.

[0011] In this solution, the arc plate assembly includes a main arc plate and an auxiliary arc plate, the outer arc surface of the auxiliary arc plate faces the inner cavity of the corner connector, and a right-angle notch is provided at the connection between the first straight plate and the second straight plate. This arrangement facilitates the formation of a large sealant filling space between the corner connector and the two panels of the clean plate, thereby avoiding the problem of insufficient sealant and sealing failure or sealant escaping when sealing the corner connector and the clean plate.

[0020] In this embodiment, the arc plate assembly, the first straight plate 102 and the second straight plate 107 are an integrally formed structure. More specifically, the corner connector 1 can be made of aluminum alloy. In other embodiments, stainless steel or other materials can also be used if the use requirements are met, which can be set by those skilled in the art.

[0021] More specifically, the arc length of the main arc plate 1042 along its own circumference is L1, and the arc length of the blocking arc plate along its own direction is L2, and L1 is much larger than L2.

[0022] In this embodiment, two parallel stop plates 101 are respectively provided on the sides of the first straight plate 102 and the second straight plate 107 facing away from the inner cavity 103, and the two parallel stop plates 101 form the plug-in positioning member, and the stop plates 101 are perpendicular to the connected first straight plate 102 or second straight plate 107.

[0023] See also Figure 2 The distance between the outer sides of two adjacent abutment plates 101 is equal to the thickness of the positioning groove 201 of the keel 2 to be inserted.

[0024] In this embodiment, a guide plate is connected to one end of the first straight plate 102 and the second straight plate 107 away from the inner cavity 103 , and a distance between the two oppositely arranged guide plates gradually decreases in a direction away from the inner cavity 103 .
