Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1, with reference to fig. 2-4, the dual-shaft folding door of the present invention comprises a plurality of folding units 1 and connecting members 2, wherein the folding units 1 are sequentially connected to the connecting members 2 at intervals to form a folding door structure, and the folding units 1 are rotatably connected to the connecting members 2, preferably hinged.
The folding unit 1 is a main component of the folding door, the folding unit 1 comprises a door panel 11 and a connecting shaft 12, the door panel 11 is a rectangular plate, and the connecting shaft 12 is fixedly arranged on two opposite side edges of the door panel.
The door plant 11 is as folding single unit, and when expanding, the whole of folding door is constituteed to a plurality of door plants 11, and during folding, a plurality of door plants 11 superpose to occupy littleer space, let the folding door open, door plant 11 can adopt plastic panel, resin panel, sheet metal or metal gauze.
The connecting shaft 12 is used as a connecting structure of the door panel 11, the connecting shaft 12 is matched with an external shaft sleeve to form a hinge structure, so that the door panel is folded, the connecting shaft 12 is fixedly arranged on two opposite side edges of the door panel 11, and the two connecting shafts 12 are parallel to each other.
Connecting piece 2 is used for connecting two adjacent folding unit 1, and make two adjacent folding unit 1 can rotate relatively, thereby realize the effect of folding and expansion, connecting piece 2 is the section bar structure of rectangular shape, first logical groove 21 and second logical groove 22 have been seted up along length direction in the surface of connecting piece 2, first logical groove 21 and second logical groove 22 are used for the connecting axle 12 of the different folding unit 1 of embedding installation respectively, as preferred scheme, first logical groove 21 and second logical groove 22 all are located same side of connecting piece 2.
The first through groove 21 and the second through groove 22 are identical in shape and size, preferably, the first through groove 21 and the second through groove 22 are arranged on the surface of the connecting piece 2 in a mirror symmetry mode, the cross sections of the groove bodies of the first through groove 21 and the second through groove 22 are arc-shaped, the angle of the arc is larger than 180 degrees and smaller than 360 degrees, preferably 270 degrees, meanwhile, the diameter of the connecting shaft 12 is slightly smaller than the diameter of the arc, so that the connecting shaft 12 can be embedded into the through groove structure to rotate, and meanwhile, the arc cannot slide out easily, the larger the angle of the arc is, the smaller the relative rotation angle of the folding units 1 is, a rotating shaft structure is formed by the way that the through grooves and the connecting shaft 12 are connected in a nesting mode, gaps can be prevented from occurring at the connecting position between the two folding units 1, therefore, the sealing effect of the folding door is better, meanwhile, the connecting, let the angle that can expand between two folding unit 1 bigger, as preferred, the angle of circular arc can select 270, and when the angular bisector of two circular arc breachs becomes 45 angles each other, folding unit 1 is parallel to each other when folding state, can be in the coplanar when the debt is opened completely.
As a preferred embodiment, when the door panel 11 is a metal screen, the edge of the door panel can be formed into a folding unit 1 by welding or inserting the connecting shaft 12, and a foldable screen door structure can be formed by connecting the connecting shaft 12 with the first through groove 21 and the second through groove 22 in a nested manner, which is simpler than a conventional screen door structure, and has higher mechanical strength and better sealing performance at the folding part.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
