[0002] The shell of the modular air handling unit is mostly made up of multiple panels, and the panels are often foam boards made of materials such as profiles, sheet metal and foam materials.

[0003] In the process of making foam boards, the profiles need to be cut into the required size and length, and then each cut profile is spliced to form the frame required for making foam boards. When splicing the profiles, every two profiles are connected, which is often achieved by using connectors at the corners of the profiles.

[0004] Currently, most products use internal connectors. When manufacturing the profile, both ends of the profile need to be beveled at 45 degrees. When the profiles are spliced together, the two bevels are joined to form a right angle, allowing the connector to be hidden inside the profile. However, this method is relatively complex to manufacture. During the production of the profile, multiple angle corrections must be made at both ends of the profile to achieve the desired angle, which results in unnecessary material waste. Furthermore, the production of the profile angle requires a high degree of precision. Any deviation in the angle will affect the external dimensions of the foam board. Furthermore, the sharp corners at both ends of the profile are prone to deformation during transportation and subsequent operations due to the limited material and poor strength.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] See also Figures 1 to 5 As shown, this embodiment provides a foam board profile connector, including:

[0035] Angle profile 1, which is arranged in a right-angled structure and has two independent inner cavities, wherein each independent cavity is further divided into a plurality of first chambers by a middle partition;

[0036] The plug-in arm 2 is formed by extending outward along the end of the angle profile 1, and the two plug-in arms 2 formed are perpendicular to each other. A second chamber connected to the first chamber is provided in the plug-in arm 2, and a plurality of positioning grooves 201 are provided on the outer wall of the plug-in arm 2 for matching with the frame profile 3 of the external device.

[0037] Specifically, in this embodiment, the present application optimizes the manufacturing process of the profile, and there is no need to correct the splicing angle, only the cutting plane is required, and cutting the plane will hardly generate waste, which can effectively save costs; at the same time, the present application sets the angle profile 1 as a right-angle structure, and the angle profile 1 and the plug-in arm 2 are an integrally formed part with a fixed angle. When the foam panel (foam board, the following content is explained with the foam board) is manufactured, there will be no angle deviation, which can effectively ensure the manufacturing accuracy.

[0038] It should be noted that the present application sets corresponding chambers in the angle profile 1 and the plug-in arm 2, with the aim of effectively reducing the overall weight while ensuring the overall stability of the frame, making the overall structure more economical.

[0039] At the same time, a plurality of positioning grooves 201 are provided on the outer wall of the plug-in arm 2 in order to facilitate accurate plug-in installation between the angle profile 1 and the plug-in arm 2 and to make the operation more convenient.

[0040] In this embodiment, the shape of the angle profile 1 is consistent with that of the frame profile 3, both of which are right-angle structures. Therefore, when the angle profile 1 and the frame profile 3 are spliced together, the shapes on both sides of the joint are consistent, thereby not affecting the use effect after splicing.

[0041] The connecting parts described in this embodiment optimize the manufacturing process, reduce profile waste, reduce the risk of profile damage, and reduce the dimensional deviation of the foam board. The structure is simple to install and easy to operate, and solves the problems of large waste generated during profile production of the foam board, complex bevel cutting process, large dimensional deviation, and easy damage.

[0042] In some embodiments, as Figures 1 to 3 As shown, a partition is provided at the corner of the angle profile 1 to form two independent inner cavities; the cross-section of the end of the angle profile 1 is L-shaped, and a convex edge 101 is extended from the edge of the angle profile 1, and the convex edge 101 matches the outer shape of the frame profile 3;

[0043] The angle profile 1 and the plug-in arm 2 are integrally formed, and the inner walls of the angle profile 1 and the plug-in arm 2 are arranged at an angle.

[0044] Specifically, in this embodiment, an installation space is reserved between the convex edges 101 formed at the inner edge of the angle profile 1. After the angle profile 1 is matched with the frame profile 3, the purpose is to reserve space for installing the plate body. The plate body here includes an inner plate, an outer plate and a foam layer filled between the inner plate and the outer plate. The plate body is installed in the installation space and connected together through the foam layer.

[0045] It should be noted that the inner wall surfaces of the angle profile 1 and the plug-in arm 2 are set as inclined surfaces in order to facilitate the installation of the board body. The entire foam board is assembled into one through the foam layer, which reduces the processing difficulty for the operator.

[0046] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the size of the plug-in arm 2 is smaller than that of the angle profile 1 , and the cut-off surface formed by the end of the angle profile 1 fits in with the end surface of the frame profile 3 .

[0047] Specifically, in this embodiment, two plug-in arms 2 are respectively connected to the angle profile 1, and the two plug-in arms 2 extend in two directions and are perpendicular to each other. The plug-in arms 2 and the angle profile 1 are made of plastic material. The size of the plug-in arms 2 is smaller than the size of the angle profile 1. The cut-off surface formed at the connection between the angle profile 1 and the plug-in arms 2 fits the cross-section of the end of the frame profile 3, and the cut-off surface formed is used to limit the matching position of the frame profile 3.

[0048] After the plug-in arm 2 is assembled with the end of the frame profile 3, the overall angle is fixed, and no angle deviation will occur during the production of the foam board, thereby ensuring the production accuracy. At the same time, the end section of the frame profile 3 and the cutoff surface of the angle profile 1 are set to be flat, which can reduce damage to the profile during transportation and subsequent operations.

[0049] In some embodiments, as Figures 1 to 3 As shown, the cross-section of the end of the plug arm 2 is L-shaped, and the positioning grooves 201 are respectively provided at the top, bottom and corner of the plug arm 2;

[0050] A chamfer 202 is provided around the end of the plug-in arm 2. The purpose of providing the chamfer 202 is to facilitate insertion into the frame profile 3 when splicing with the frame profile 3.

[0051] Specifically, in this embodiment, positioning grooves 201 are respectively provided at the top, bottom and corners of the plug-in arm 2, in order to ensure that the angle profile 1 and the frame profile 3 fit tightly after installation, and to effectively prevent the angle profile 1 and the frame profile 3 from being loosely fitted during fitting.

[0052] In some embodiments, as Figure 1 and Figure 3As shown, the outer wall and the bottom end of the plug arm 2 are respectively provided with a plurality of ribs 203 , and the plurality of ribs 203 are arranged in parallel.

[0053] Specifically, in this embodiment, during the actual splicing process, if the inner wall surfaces of the plug-in arm 2 and the frame profile 3 are both flat, the contact between the two surfaces during plugging will produce greater resistance, which is inconvenient to operate. Therefore, the present application sets a plurality of ribs 203 on the outer wall and bottom end of the plug-in arm 2, and utilizes the set ribs 203 to contact the inner wall surface of the frame profile 3, which can facilitate the splicing of the corner profile 1 and the frame profile 3.

[0054] In some embodiments, as Figure 2 As shown, a groove 204 extending into the angle profile 1 is further provided on the outer wall of the plug-in arm 2 , and the groove 204 is used to form an exhaust passage.

[0055] In this embodiment, during the process of making the foam panel, gas is generated during the process of filling the foam material. Then, the gas generated during the filling of the foam material can be discharged with the help of the exhaust channel to ensure that the foam material is fully filled.

[0056] Based on the same inventive concept, corresponding to any of the above-mentioned connecting pieces, the embodiment of the present application further provides a box frame, such as Figure 5 As shown, it is composed of a plurality of frame profiles 3 and a connector connecting the plurality of frame profiles, and the connector adopts the foam board profile connector as described in the above embodiment;

[0057] like Figure 6 As shown, the frame profile 3 includes a first profile 301 and a second profile 302 plugged into the first profile 301 , and plug-in strips 303 matching the positioning groove 201 are provided on the inner walls of the first profile 301 and the second profile 302 .

[0058] Specifically, in this embodiment, plug-in strips 303 matching the positioning grooves 201 are respectively provided on the first profile 301 and the second profile 302 to ensure accurate splicing of the plug-in arm 2 and the two profiles. At the same time, retaining strips are provided on the inner walls of the first profile 301 and the second profile 302 to engage with the edge parts of the angle profile 1 and the plug-in arm 2, and the plug-in strips 303 provided in combination effectively ensure the overall sealing after splicing.

[0059] During assembly, if Figure 4 and Figure 5 As shown, through the action of the chamfer 202 and the positioning groove 201, the plug-in arm 2 can be accurately inserted into the frame profile 3. During the plug-in process, when the end cross-section of the frame profile 3 is tightly fitted with the cut-off surface of the angle profile 1, the plug-in arm 2 is accurately installed on the frame profile 3, and the other side is also installed in the same way. After the four corners are installed, a complete foam board profile frame will be formed.
