Description

Technical Field

[0001] This utility model relates to the field of air conditioner structural components, specifically to an air conditioner housing frame. Background Technology

[0002] Conventional air conditioner frame connection methods are complex, with too many connection types within a single frame. The presence of multiple connection methods within a single frame can compromise the safety of the frame's connection strength. Furthermore, too many connection types within a single frame increase processing costs, lead to difficulties in on-site material handling, and increase the likelihood of assembly errors, thus reducing assembly efficiency. Therefore, ensuring the connection strength of the air conditioner frame while improving assembly efficiency and reducing production costs has become a key issue we need to consider. Conventional air conditioner side panels are connected directly to the frame via folded edges. The openings in the folded edges affect the strength of the side panels themselves, and fastener installation is difficult during side panel installation. Therefore, ensuring the connection strength of the air conditioner side panels while improving assembly efficiency has become a key issue we need to consider. Utility Model Content

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, Figure 1 This is a schematic diagram of the structure of an air conditioner housing frame according to the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of an air conditioner housing frame according to the present invention. Figure 2 ; Figure 3 for Figure 2 An enlarged schematic diagram of part A in the middle; Figure 4This is a structural schematic diagram of a three-way connector for an air conditioner housing frame according to the present invention. The air conditioner housing frame includes four vertical square tube support columns 10, eight square tube connecting beams 20, multiple horizontal connecting strips 30, multiple side plate connectors 50, eight three-way connectors 40, and multiple shell plates 60. Each three-way connector 40 includes a first square tube 41, a second square tube 42, and a third square tube 43. One end of the first square tube 41 is welded to one end of the second square tube 42, and the third square tube 43 is welded to the welding surfaces of the first square tube 41 and the second square tube 42. Each of the first square tube 41, the second square tube 42, and the third square tube 43 has multiple threaded connection holes 44. The upper ends of the four vertical square tube support columns 10 are inserted into the first square tubes 41 of the four upper-positioned three-way connectors 40. The four vertical square tube support columns 10 are connected and fixedly connected by screws through the threaded connection holes 44. The lower ends of the four vertical square tube support columns 10 are inserted into the first square tubes 41 of the four lower tee connectors 40 and fixedly connected by screws through the threaded connection holes 44. The four upper square tube connecting beams 20 are inserted into the second square tubes 42 and third square tubes 43 of the four upper tee connectors 40. The four lower square tube connecting beams 20 are inserted into the second square tubes 42 and third square tubes 43 of the four lower tee connectors 40. The multiple horizontal connecting strips 30 are connected to the vertical square tube support columns 10 by threaded connection. The multiple side plate connectors 50 are fastened to the vertical square tube support columns 10 by threaded connection. The four corners of the multiple shell plates 60 are connected to the multiple side plate connectors 50 by threaded connection.

[0020] As a three-dimensional connector, the tee connector serves to position and fix the four vertical square tube support columns and eight square tube connecting beams in the X, Y, and Z directions. The tee connector is composed of three square tubes welded together. The three square tubes are placed in the X, Y, and Z directions. At the common joint end of the first and second square tubes, the first and second square tubes need to be cut at a 45-degree angle to form a common square tube part at the junction. Then, the end of the third square tube is welded to the joint surface to securely connect them.

[0021] As a three-dimensional connector, the tee connector serves to position and fix the four vertical square tube support columns and eight square tube connecting beams in the X, Y, and Z directions. The square tubes are equipped with various threaded connection holes, which can be fastened to the four vertical square tube support columns and eight square tube connecting beams with screws. Threaded connection holes are also provided on the vertical square tube support columns. The side plate connector is fixedly connected to the vertical square tube support columns with screws, and the shell plate is fixedly connected to the side plate connector with screws.

[0022] To facilitate the pre-fixation and threaded fastening of the four vertical square tube support columns, eight square tube connecting beams, and square copper tubes, preferably, the length of the pipe opening 45 of the first square tube 41, the second square tube 42, and the third square tube 43 is less than the length of the pipe opening of the vertical square tube support column 10 and the square tube connecting beam 20, and the width of the pipe opening 45 of the first square tube 41, the second square tube 42, and the third square tube 43 is less than the width of the pipe opening of the vertical square tube support column 10 and the square tube connecting beam 20.

[0023] Four vertical square tube support columns and eight square tube connecting beams are inserted into the square tubes and snapped into place inside the square tubes. They are then fixed in place by external threads in the vertical direction of the square tubes, making the entire frame more robust.

[0024] like Figure 5 , Figure 6 As shown, Figure 1 This is a schematic diagram of the structure of a corner piece in this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the structure of a corner piece in this utility model. Figure 2 Preferably, the side plate connector 50 has a square tube connector 51 and a side plate connector 52. The square tube connector 51 is fixedly connected to the vertical square tube support column 10 through two screw connection holes, and the side plate connector 52 is fixedly connected to one corner of the shell plate 60 through one screw connection hole.

[0025] By using new side panel connectors to connect the frame and the side panels, the connection strength between the side panels and the frame is ensured, while the appearance becomes simple and elegant, greatly reducing the difficulty of installing the side panels.

[0026] The fixing direction of the fasteners is changed by using the side plate connector. The side plate connector itself is an L-shaped small bend. The bend is connected to the frame, and the other side bend is connected to the end face of the side plate. The end face of the side plate is countersunk to ensure a simple and elegant appearance.

[0027] By using L-shaped small bending parts to connect the frame and the side panels, the connection strength between the side panels and the frame is ensured, while the appearance becomes simple and elegant, greatly reducing the difficulty of installing the side panels.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] Designing the T-joint as a three-dimensional, three-sided structure effectively reduces the types of air conditioner frame connections, lowering production costs. It also significantly improves assembly efficiency, preventing assembly errors that could lead to rework and lower product yield. The assembly of the outer frame reduces the workload for production personnel, and the connection between the frame's supports and beams via the T-joint effectively minimizes assembly abnormalities caused by human error. Using the T-joint also ensures the frame's connection strength, results in a cleaner and more aesthetically pleasing appearance, and prevents frame wobbling and breakage. Furthermore, using side panel connectors to connect the frame and side panels ensures strong connection strength while maintaining a simple and elegant appearance, greatly reducing the difficulty of side panel installation.

[0030] In addition, this utility model also provides a frame, such as Figure 5 , Figure 6 As shown, Figure 5 This is a schematic diagram of the structure of a frame in this utility model; Figure 6 In this utility model Figure 5 The diagram shows a partially enlarged view of the AA frame. The frame includes eight horizontal beams, four vertical beams, and four corner pieces. As described above, each corner piece includes a corner protector, three legs, and three internal connectors. The legs are square tubular structures, with the first end of each leg having two 45-degree cuts. The first ends of the three legs are welded together to form a fixed angle. The corner protector covers and wraps around the fixed angle, and the corner protector and the fixed angle are fixedly connected by welding. The internal connectors are inserted into the legs. Both the legs and the internal connectors have multiple fixing holes. The horizontal beams and vertical beams are square tubular structures. The horizontal beams and vertical beams are fitted onto the outer surface of the three legs and are fixedly connected to the corner pieces and internal connectors through threaded connection fixing holes.

[0031] One end of a vertical beam is fitted onto the support square tube below the upper corner piece, and the other end is fitted onto the support square tube above the lower corner piece. The upper ends of the four vertical beams are respectively fitted onto the support square tubes below the four upper corner pieces, and the other ends are fitted onto the support square tubes above the four lower corner pieces. The vertical beams have fixing holes that match the corner pieces, and the vertical beams are pre-fixed to the corner pieces by screws.

[0032] There are eight crossbeams, divided into four upper crossbeams and four lower crossbeams. One end of the upper crossbeam is fitted onto one upper corner piece in the X or Y direction, and the other end is fitted onto another upper corner piece in the X or Y direction. One end of the lower crossbeam is fitted onto one lower corner piece in the X or Y direction, and the other end is fitted onto another lower corner piece in the X or Y direction. Pre-fixing is performed first, and after all the crossbeams and vertical beams are properly fitted, they are reinforced and tightened.

[0033] The horizontal and vertical beams are fixed by screws passing through the fixing holes and threaded connections to the built-in connectors inside the support square tubes.

[0034] By using corner brackets for framing, the positioning accuracy is higher and there is less interference during fastening compared to manual frame assembly. Assembly can be completed by just one person, saving time and effort.

[0035] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting short square tubes in the length, width and height directions and fixing these three square tubes together to form a fulcrum, when assembling the frame, it is only necessary to put the horizontal beam and vertical beam on the square tube for pre-fixing and pre-positioning, and then tighten them with threads, which can improve the positioning accuracy of the frame, improve the load-bearing capacity of the frame, and also save time and effort.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
