[0013] like Figure 1 As shown, an embodiment of the present application provides a corner structure of a cold-bridge air-conditioning box, including three square structural profiles 100 and a triangular plug-in 200 .
[0014] The square structural profile 100 has a specification of 40x40cm, such as Figure 2 As shown, it includes an outer plate 110 , two cold-insulating connecting plates 120 and an angle piece 130 .
[0015] The cross-section of the outer panel 110 is L-shaped, the two cold-breaking connecting plates 120 are parallel to the horizontal and vertical sections of the outer panel 110, the corner pieces 130 are arranged diagonally to the corners of the outer panel 110, and the four together form a square. The cavity formed by the enclosed is provided with an insulating filler 111, such as a polyurethane foam filler.
[0016] The outer plate 110 is made of aluminum alloy, and has first slots on the inner sides of both ends thereof.
[0017] In order to improve the strength, the thickness of the two ends of the outer plate 110 is greater than the thickness of the remaining parts thereof, and the thickness is further increased at the position where the first slot is set.
[0018] The cold-insulating connecting plate 120 is made of ABS plastic material, and has a first clamping portion 121 and a second clamping portion 122 at both ends thereof, and the first clamping portion 121 is clamped with the corresponding first clamping slot. Figure 2 As shown, taking the horizontal cold-break connecting plate 120 as an example, the first clamping portion 121 at the right end thereof is clamped with the first clamping groove on the inner side of the vertical section of the outer plate 110 .
[0019] The angle piece 130 is made of aluminum alloy and has two second clamping grooves that are respectively clamped with the second clamping parts 122 of the corresponding cold-insulating connecting plates 120 .
[0020] Specifically, the corner piece 130 includes an L-shaped outer contour plate 131 opposite to the corner of the outer plate 110 and an L-shaped inner contour plate 132 connected to the L-shaped outer contour plate 131. The horizontal section and the vertical section of the L-shaped inner contour plate 132 respectively form second card grooves. Taking the horizontal cold-break connecting plate 120 as an example, the second card portion 122 at its left end is card-engaged with the second card groove on the vertical section of the L-shaped inner contour plate 132.
[0021] like Figure 4 As shown, in the existing structural profiles, there is a gap B between the corner frame material 3 and the outer frame material 1, which causes a bite with the adjacent plate during installation. In order to overcome this problem, in this embodiment, the cold-breaking connecting plate 120 is located between the corresponding end of the L-shaped outer contour plate 131 of the corner piece 130 and the corresponding end of the outer plate 110. The two ends of the cold-breaking connecting plate 120 are bent inwardly to form a first clamping portion 121 and a second clamping portion 122 respectively. Such a structure can avoid the formation of a gap between the L-shaped outer contour plate 131 and the outer plate 110.
[0022] Preferably, the outer surface of the cold-insulating connecting plate 120 is flush with the outer surface of the corresponding section of the L-shaped outer contour plate 131 and the end surface of the corresponding end of the outer plate 110 .
[0023] Taking the transverse cold-breaking connecting plate 120 as an example, it is located between the end of the transverse section of the L-shaped outer contour plate 131 and the end of the vertical section of the outer plate 110. The outer side surface of the cold-breaking connecting plate 120 is flush with the outer surface of the transverse section of the L-shaped outer contour plate 131 and the end face of the vertical section of the outer plate 110.
[0024] Wherein, the first card slot and the second card slot are both dovetail slots.
[0025] like Figure 3As shown, the triangular plug-in 200 is made of ABS plastic material, which includes a cubic block. The three adjacent faces of the cubic block respectively form a seat body 210. The cross-section of the seat body 210 is square and the size is consistent with the face of the cubic block. A plug 220 is formed on each seat body 210, so that the triangular plug-in 200 has three plugs in the front and back, left and right, and up and down directions.
[0026] The plug 220 is tubular, and a socket corresponding to the plug 220 is formed on the heat-insulating filler in the cavity of the square structural profile 100 .
[0027] In order to make the connection between the plug 220 and the square structural profile 100 more secure, the outer peripheral surface of the plug 220 has a plurality of arc-shaped grooves 221 extending along the length direction of the plug and concave inwardly, and the slope of the arc-shaped grooves is 1.5-2 degrees.
[0028] The seat body 210 is provided with a blanking receiving groove 211 located on the outer side of the plug 220 thereon, for receiving blanking generated when the plug 220 is plugged into the socket, such as Figure 2 As shown, the outline of the plug 220 is substantially consistent with the inner outline of the cavity of the square structural profile 100. When the plug 220 is plugged into the socket, material is easily dropped at the position of the socket close to the corner piece 130. Therefore, the seat body 210 is provided with a drop receiving groove 211 at the corresponding position.
[0029] From the above, it can be seen that the square structural profile of the corner structure of the cold-break bridge air-conditioning box provided in the embodiment of the present application is composed of an outer panel, two cold-break connecting plates and corner pieces. Compared with the existing square structural profiles of the same specification, the length of the cold-break connecting plate is increased, which can effectively cut off the transfer of cold air, and the area of the insulating filler is also increased, thereby improving the thermal insulation performance.
[0030] In addition, the position of the cold-break connecting plate can avoid gaps between the outer plate and the corner fittings, preventing the occurrence of bite.
[0031] Obviously, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
