Description

Technical Field

[0001] The utility model relates to the technical field of door leaf production, in particular to an assembled edge structure for a door leaf. Background Art

[0002] At present, the edge structures of mother-daughter and double-leaf door products on the market are basically integral edge structures. When the door leaf is produced and formed, it needs to be produced together with the edge.

[0003] Since the sizes of the door leaves are different, for the production equipment of the edge part, although the sizes and shapes of the edges are basically the same, because the edge and the door leaf are an integral structure, it is necessary to adapt to door leaves of different sizes. This makes the whole production equipment numerous and increases the production cost.

[0004] Therefore, it is necessary to propose an assembled edge structure for a door leaf to realize the separate production of the door leaf and the edge, reduce the production equipment for the edge, and then assemble the edge and the door leaf during assembly. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose an assembled edge structure for a door leaf to realize the separate production of the door leaf and the edge, reduce the production equipment for the edge, and then assemble the edge and the door leaf during assembly.

[0006] The purpose of the utility model is achieved by the following technical solutions: an assembled edge structure for a door leaf, including an edge base and an edge cover plate detachably arranged on the sub-door leaf. The edge base is provided with a first connecting member and a second connecting member. The first connecting member and the second connecting member are arranged oppositely. A first protruding portion is arranged on the opposite sides of the first connecting member and the second connecting member. One side of the edge cover plate is provided with a third connecting member and a fourth connecting member. The third connecting member and the fourth connecting member are arranged oppositely and are matched with the first connecting member and the second connecting member. A second protruding portion matched with the first protruding portion is arranged on the adjacent side of the third connecting member and the fourth connecting member.

[0007] The first connecting member, the second connecting member, the third connecting member, the fourth connecting member, the first protruding portion and the second protruding portion are all supported by elastic materials.

[0008] The sub-door leaf is connected to the edge base through fixing rivets.

[0009] A fan is arranged in the fermentation body.

[0010] The side where the first protruding portion and the second protruding portion are in close contact is an R-shaped arc.

[0011] A force application portion is arranged on the edge cover plate.

[0012] A placement space for placing a sealing strip is provided on the force application part.

[0013] The beneficial effects of the present utility model are as follows: By providing the first connecting part, the second connecting piece, the third connecting piece, the fourth connecting piece, the first protruding part and the second protruding part, the overlapping cover plate and the overlapping base are convenient to install. By providing that the overlapping base is detachably connected to the sub-door leaf, the overlapping part and the door leaf can be assembled separately, so as to realize the separate production of the door leaf and the overlapping part, reduce the production equipment for the overlapping part, and then assemble the overlapping part and the door leaf during assembly.

Detailed Embodiment

[0020] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] It should be noted that the orientation concepts of "left", "right", "up", "down", "front", "rear", "inner", and "outer" in the following solutions are all relative directions, and will not be listed one by one here.

[0022] A door leaf assembled overlapping structure, referring to Figure 1 - Figure 2 , includes a mutually matching sub-door leaf 1 and a mother door leaf 6. The overlapping base 2 is connected to the sub-door leaf 1 through a fixing rivet 4.

[0023] The edge connecting base 2 is provided with a first connecting member 21 and a second connecting member 22. On the opposite sides of the upper ends of the first connecting member 21 and the second connecting member 22, there are first protruding portions 23 provided. On the opposite sides of the first protruding portions 23, there are R-shaped arcs 7. On the lower side of the edge connecting cover plate 3, there are a third connecting member 31 and a fourth connecting member 32. A force applying portion 34 is connected beside the fourth connecting member 32. There is a placement space 35 between the force applying portion 34 and the mother door leaf 6. A sealing strip 5 is placed in the placement space 35. The third connecting member 31, the fourth connecting member 32 are corresponding to the positions of the first connecting member 21 and the second connecting member 22. On the adjacent sides of the third connecting member 31 and the fourth connecting member 32, there are second protruding portions 33 provided. The second protruding portions 33 are matched with the first protruding portions 23. The parts where the second protruding portions 33 are in close contact with the first protruding portions 23 are R-shaped arcs 7. When the first protruding portions 23 and the second protruding portions 33 are in close contact, the two form a snap structure.

[0024] Reference Figure 3 - Figure 5 , when the edge connecting cover plate 3 is installed on the edge connecting base 2, the edge connecting cover plate 3 is assembled at the A part in the direction of the arrow in Figure 4 , and then snap-fitted at the B part in the direction of the arrow in the figure. As Figure 5 shown, when the sub-door leaf 1 is opened and closed, the edge connecting cover plate 3 will be subjected to the thrust in the direction of the arrow in the figure. Due to the special structural design of the mating part between the edge connecting cover plate 3 and the edge connecting base 2, there will be no problem of the cover plate being pushed off.

[0025] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above description or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
