Description

Technical Field

[0001] The utility model relates to a foaming door panel, in particular to a foaming and filling door panel. Background Art

[0002] Foam doors fill door panels with foam material, which not only greatly reduces the weight of the door panels, but also provides sound insulation and heat insulation.

[0003] Patent application number 201410252159.2 discloses a foam door structure and manufacturing method. The foam door structure includes a top plate and a bottom plate, with a foaming cavity separated between the top and bottom plates. A feed block is provided at the edge of the foaming cavity, with a feed port provided on the feed block, which is connected to the foaming cavity. The foaming cavity is filled with a foam board layer. Multiple support blocks are fixedly connected between the top and bottom plates, and the support blocks are arranged at the corners of the top and bottom plates.

[0004] In the above patent, the door body structure is hollowed out to form a foaming cavity, which is supported by the support block during filling and then filled from the feed block. This structure will increase the complexity of the door body structure, that is, the top plate and the bottom plate need to be installed first to form a foaming cavity, and then the support block and the feed block are used to foam. This will undoubtedly increase the manufacturing difficulty and lead to increased costs. Utility Model Content

[0005] Based on the shortcomings of the prior art that the power supply and controller installation positions have poor heat dissipation effects and are prone to spontaneous combustion, the utility model provides a foam-filled door panel.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] Foam padded door panel, including:

[0008] The upper plate has a rectangular structure with rectangular notches at its four corners, two long edges with L-shaped hems formed by bending twice, and two short edges with straight hems formed by bending once;

[0011] The second frame has two pieces and is in a chevron-shaped structure. Its length is the same as the long side of the upper plate. It is set at the edge between the upper plate and the lower plate, and the L-shaped folded edges are hooked on both sides of the chevron-shaped structure. The two second frames and the two first frames together form a rectangular frame structure;

[0012] a filling hole, which is provided on the first frame or the second frame;

[0013] The foam filling layer is distributed in the cavity formed by the upper plate body, the lower plate body and the rectangular frame structure.

[0032] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0034] This embodiment mainly describes the topic of the foam-filled door panel, which is as follows:

[0035] Foam filled door panel, reference Figures 1-6 ,include:

[0036] The upper plate 10 is a rectangular structure with rectangular notches at its four corners. Its two long edges are provided with L-shaped folds 01 formed by bending twice, and its two short edges are provided with straight folds 02 formed by bending once;

[0037] The lower plate 20 is symmetrical with the upper plate 10 and spaced apart;

[0038] The first frame 30 has two square structures and is shorter than the length of the short side of the upper plate 10. It is arranged at the short side edge between the upper plate 10 and the lower plate 20, and the straight folded edge 02 is close to the outer wall of the square structure;

[0039] The second frame 40 has two members and is in a chevron-shaped structure. Its length is the same as the long side of the upper plate 10. It is arranged at the edge between the upper plate 10 and the lower plate 20, and the L-shaped folded edge 01 is hooked on both sides of the chevron-shaped structure. The two second frames 40 and the two first frames 30 together form a rectangular frame structure 03;

[0040] a filling hole 70 , which is provided on the first frame 30 or the second frame 40 ;

[0041] The foam filling layer 80 is spread throughout the cavity formed by the upper plate 10, the lower plate 20 and the rectangular frame structure 03. During manufacturing, the plate is first cut, and after cutting, the L-shaped fold 01 is flanging by a flanging machine. Then, the wooden frame is assembled and inserted between the two plates and the L-shaped fold 01 is hooked on the second frame 40. The plates on both sides of the first frame 30 are flanging, and finally, after being clamped by a clamp, the cavity is filled with foam material from the filling hole 70 using a filling device. This solution forms a cavity for foam filling by enclosing two plates and a frame. The two plates only need to be cut and formed and then folded to complete the installation with the wooden frame. The plate structure is greatly simplified and installation is also more convenient, which effectively reduces the difficulty of the manufacturing process and reduces production costs. The final product is not only lightweight, but also has significantly improved thermal insulation and sound insulation.

[0042] Preferably, both ends of the first frame 30 abut against the inner sidewalls of the second frame 40. The abutting structures form a rectangular frame, which not only plays a supporting role, but also forms a cavity for filling together with the plate body.

[0043] Specifically, the length of the straight fold 02 is less than or equal to the length of the first frame 30 ; the length of the L-shaped fold 01 is equal to the length of the second frame 40 .

[0044] Preferably, the first frame 30 and the second frame 40 are both wooden frames. Wooden frames have sufficient support and are lightweight.

[0045] Preferably, the upper plate 10 and the lower plate 20 are metal plates, which are used to increase structural strength and are less likely to break during use. The preferred metal plates are iron plates.

[0046] As an advantage, the grooves on both sides of the second frame 40 are provided with plugging strips 50, which compress the L-shaped folding edge 01. After being tightened by the plugging strips 50, the stability of the door panel can be improved.

[0047] Preferably, a limiting structure is provided at the position where the first frame 30 and the second frame 40 abut against each other, and the two are limited by the limiting structure. The limiting structure can ensure the stability of the rectangular frame structure 03 formed by the two sets of frames.

[0048] Preferably, the limiting structure is a mortise and tenon structure; or the limiting structure includes a limiting groove 601 provided on one of the frames and a spring pin 602 embedded in the other frame and cooperating with the limiting groove 601.

[0049] Preferably, the exposed parts of the upper plate 10, the lower plate 20, the first frame 30 and the second frame 40 are provided with protective paint after installation.

[0050] The above is a detailed introduction to the title of the foam-filled door panel provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the present invention.
