Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a composite profile frame. Background Art

[0002] Composite profile frames are frame structures made of profiles made from two or more different materials. This structure combines the advantages of different materials to achieve better mechanical properties, corrosion resistance, and lightweighting. Composite profile frames are widely used in construction, transportation, machinery and other fields.

[0003] However, existing composite profiles typically incorporate a flexible contact sheet directly between the inner and outer frames, while also providing a connection slot on the inner side of the inner frame for connecting to glass or wall panels. This single contact sheet cannot effectively provide a cushioning effect, and is prone to aging and breakage after prolonged use, resulting in poor stability.

[0004] At the same time, directly opening the connection groove on the inner frame reduces the strength of the inner frame, and the inner frame is prone to breakage during actual use, further reducing its stability. Summary of the Invention

[0005] The purpose of the utility model is to provide a composite profile frame with high stability and compact structure in order to solve the above problems existing in the prior art.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A composite profile frame, characterized in that it includes an inner frame, an outer frame, a flexible contact component one and a flexible contact component two, the inner frame and the outer frame are both rectangular frame structures, the inner frame is located in the outer frame and the flexible contact component one is located between the inner frame and the outer frame, the inner side of the inner frame has a recessed connecting groove, and the flexible contact component is located at the connecting groove.

[0008] In the above-mentioned composite profile frame, the flexible contact component 1 includes a flexible isolation part, a connection part 1 and a connection part 2. The above-mentioned connection part 1 is connected to the middle part of the inner frame, and the above-mentioned connection part 2 is connected to the middle part of the outer frame. The two ends of the above-mentioned isolation part are respectively connected to the inner frame and the outer frame, and the isolation part is tightly pressed between the connection part 1 and the connection part 2.

[0009] In the composite profile frame, the outer edge of the inner frame has a protruding connecting edge, the inner edge of the inner frame is connected to a retaining edge, and the connecting groove is formed between the connecting edge and the retaining edge.

[0010] In the above-mentioned composite profile frame, the connecting edge and the inner frame are an integrated structure.

[0011] In the above composite profile frame, the retaining edge is fixed to the inner frame by screws.

[0012] In the composite profile frame, the retaining edge has a cylindrical positioning portion, the inner end of the screw is connected to the inner frame, and the outer end of the screw is embedded in the positioning portion and the two are threadedly connected.

[0013] In the above-mentioned composite profile frame, the flexible contact component 2 includes contact piece 1 and contact piece 2, the inner side of the above-mentioned contact piece 1 is connected to the connecting edge, the inner side of the above-mentioned contact piece 2 is connected to the retaining edge, and the outer side of the above-mentioned contact piece 1 is opposite to the outer side of the contact piece 2.

[0014] In the composite profile frame, the connecting edge has a recessed positioning groove 1, the inner side of the contact piece 1 has a connecting section 1 matching the positioning groove 1, and the connecting section 1 is connected to one location in the positioning groove.

[0015] In the composite profile frame, the retaining edge has a protruding connecting rib, the inner side of the second contact piece has a second positioning groove matching the connecting rib, and the connecting rib is embedded in the second positioning groove.

[0016] In the composite profile frame, the outer side of the first contact piece is a first contact portion having a concave-convex shape, and the outer side of the second contact portion is a second contact portion having a concave shape.

[0017] Compared with the existing technology, the composite profile frame is connected to the inner frame with a flexible connection part 1, and the outer frame with a flexible connection part 2. The flexible isolation part is connected to the inner frame and the outer frame respectively, and the isolation part is tightly pressed between the connection part 1 and the connection part 2. Therefore, the load between the inner frame and the outer frame is borne by the combination of the connection part 1, the isolation part and the connection part 2. This not only makes the inner frame and the outer frame stably connected, but also has better buffering and heat insulation properties.

[0018] At the same time, the connecting edge and the retaining edge form a concave connecting groove on the upper part of the inner frame, which does not affect the strength of the inner frame and further improves its stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 As shown, the composite profile frame includes an inner frame 1, an outer frame 2, a flexible contact component 1 and a flexible contact component 2. The inner frame 1 and the outer frame 2 are both rectangular frame structures. The inner frame 1 is located inside the outer frame 2 and the flexible contact component 1 is located between the inner frame 1 and the outer frame 2. The inner side of the inner frame 1 has a recessed connecting groove, and the flexible contact component is located at the connecting groove.

[0025] The inner frame 1 and the outer frame 2 are made of aluminum alloy.

[0026] Under the action of the flexible contact component 1, not only can the direct rigid contact between the inner frame 1 and the outer frame 2 be avoided, but the flexible contact component 1 also plays a proper sealing, heat insulation and sound insulation role.

[0027] This composite profile frame is used to connect glass or wall panels inside it, and the edges of the glass or wall panels are embedded in the connecting groove. Under the action of the flexible contact component 2, the frame can avoid rigid contact with the glass or wall panels, and also play a proper sealing, heat insulation and sound insulation role.

[0028] The flexible contact component 1 includes a flexible isolation part 3, a connection part 1 4 and a connection part 2 5. The connection part 1 4 is connected to the middle part of the inner frame 1, and the connection part 2 5 is connected to the middle part of the outer frame 2. The two ends of the isolation part 3 are respectively connected to the inner frame 1 and the outer frame 2, and the isolation part 3 is tightly pressed between the connection part 1 4 and the connection part 2 5.

[0029] The ends of the isolation portion 3 are connected to the inner frame 1 and the outer frame 2, respectively. Furthermore, a connection portion 1 4 is connected to the inner frame 1, and a connection portion 2 5 is connected to the outer frame 2. The isolation portion 3, connection portion 1 4, and connection portion 2 5 are all made of flexible materials. This allows the connection portion 1 4, connection portion 2 5, and isolation portion 3 to share the load between the inner frame 1 and the outer frame 2. This not only effectively improves the stability of the connection, but also, because the three components bear relatively little load, they are less susceptible to damage and have relatively high stability.

[0030] The outer edge of the inner frame 1 has a protruding connecting edge 1 a , and the inner edge of the inner frame 1 is connected to a retaining edge 6 , and the connecting groove is formed between the connecting edge 1 a and the retaining edge 6 .

[0031] The connecting edge 1 a extending out from the edge of the inner frame 1 will not affect the strength of the inner frame 1 , and the retaining edge 6 fixedly connected to the inner frame 1 will not affect the strength of the inner frame 1 either.

[0032] Compared with directly making grooves on the inner frame 1, the connecting groove formed between the connecting edge 1a and the retaining edge 6 can ensure the original strength of the inner frame 1. On the contrary, making grooves on the inner frame 1 will reduce the strength of the inner frame.

[0033] The connecting edge 1a and the inner frame 1 are an integrated structure.

[0034] This can appropriately improve the structural compactness of the inner frame 1.

[0035] The retaining edge 6 is fixed to the inner frame 1 by screws 7 .

[0036] The retaining edge 6 has a cylindrical positioning portion 6a, the inner end of the screw 7 is connected to the inner frame 1, and the outer end of the screw 7 is embedded in the positioning portion 6a and the two are threadedly connected.

[0037] Under the action of the screws 7 and the positioning portion 6a, the retaining edge 6 and the inner frame 1 can be stably connected together.

[0038] The flexible contact component 2 includes a contact piece 1 8 and a contact piece 2 9. The inner side of the contact piece 1 8 is connected to the connecting edge 1a, the inner side of the contact piece 2 9 is connected to the retaining edge 6, and the outer sides of the contact piece 1 8 and the outer sides of the contact piece 2 9 are opposite to each other.

[0039] Under the action of the contact piece 1 8 and the contact piece 2 9, the glass or wall panel can be prevented from rigidly contacting with the frame.

[0040] The connecting edge 1a has a recessed positioning groove 1a1, and the inner side of the contact piece 8 has a connecting section 1 that matches the positioning groove 1a1, and the connecting section 1 is connected to the positioning groove 1a1.

[0041] Such a structure can stably connect the contact piece 8 to the connecting edge 1a.

[0042] The retaining edge 6 has a protruding connecting rib 6b, and the inner side of the second contact piece 9 has a second positioning groove 9a that matches the connecting rib 6b, and the connecting rib 6b is embedded in the second positioning groove 9a.

[0043] Such a structure can stably connect the contact piece 2 9 to the retaining edge 6 .

[0044] The outer side of the contact piece 1 8 is a concave-convex contact portion 1 8b, and the outer side of the contact portion 2 9 is a concave contact portion 2 9b.

[0045] Under the action of the contact portion 1 8b and the contact portion 2 9b, the connection stability between the glass or wall panel and the inner frame can be ensured.

[0046] This composite profile frame creatively sets a flexible connecting part 1 on the inner frame and a flexible connecting part 2 on the outer frame. The two ends of the isolation part are connected to the inner frame and the outer frame. At the same time, the isolation part is tightly pressed on the connecting part 1 and the connecting part 2. Such a structure can not only stably connect the inner frame and the outer frame, but also achieve good sealing, heat insulation and sound insulation.

[0047] At the same time, the connecting groove is not directly opened on the inner frame, but is formed between the connecting edge and the retaining edge, which does not reduce the strength of the inner frame and effectively improves the strength of the entire composite profile frame.

[0048] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described 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.

[0049] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
