The door bodies 1 are all provided with horizontal profiles 11, which belong to the existing door body 1 composition structure, including two horizontal profiles 11 located above and below the door body 1, and two vertical profiles 12 located on the left and right of the door body 1. It should be noted that the ends of the two horizontal profiles 11 on each door body 1 are provided with slots 110, and the length of the slots 110 is equal to the length of the horizontal profiles 11, that is, the slots 110 pass through the two end faces of the horizontal profiles 11, the hinges 2 are provided between the two adjacent door bodies 1, and the folding connection of the two door bodies 1 preferably adopts two hinges 2, that is, Figure 5-7 As shown, the two hinges 2 are respectively located at the ends of the upper and lower sides of the two door bodies 1, and the hinges 2 include two fixed plates 21 hinged to each other, one of the fixed plates 21 is inserted into the slot 110 of one door body 1, and the other fixed plate 21 is inserted into the slot 110 of the adjacent door body 1, and the two fixed plates 21 and the slots 110 facing each other are respectively provided with recesses 211, and the recesses 211 are arc-shaped. The two arc-shaped recesses 211 are combined to form a mounting hole, and the mounting hole is provided with a fixing screw 23, which is used to open the two recesses 211, so that the fixing plate 21 remains tightly against the notch of the slot 110.
[0022] The utility model discloses a sheet hinge folding door structure principle and effect. The two fixing plates 21 of the hinge 2 are hinged to each other through the hinge arm 22. When installing, first insert one fixing plate 21 into the end face of the horizontal profile 11 on the upper and lower sides of a door body 1, and insert it from the slot 110 at the end of the horizontal profile 11. At this time, insert the other fixing plate 21 into the horizontal profile 11 on the upper and lower sides of the adjacent door body 1. After also inserting it into the slot 110, use the fixing screw 23 to screw it into the installation hole from the end face of the horizontal profile 11. At this time, the folding door is installed. Figure 5When the folding door is in the closed state, the two fixing plates 21 of the same hinge 2 are in the same straight line. No matter it is in the open state or the closed state, the hinge 2 is at the upper and lower ends of the two adjacent door bodies 1 of the folding door. In addition, the hinge 2 structure can be further covered by the cover plate 120 on the vertical profile 12; by inserting the two fixing plates 21 on the hinge 2 into the slots 110 at the upper and lower ends of the two adjacent door bodies 1, and using the fixing screws 23 on the mounting holes to open, the fixing plates 21 are tightly against the inner wall of the slot 110, thereby achieving the fixation of the hinge 2 and the door body 1. Fixed connection, easy to install, the fixing screws 23 enter from the end face of the horizontal profile 11, compared with the traditional hinge installation, which requires multiple screws to be passed through the two leaves and inserted into the vertical profile 12, which is more convenient for people to operate and install. At the same time, the fixing plate 21 is inserted into the horizontal profile 11, and the fixing plate 21 and the horizontal profile 11 are in contact with each other up and down, which can support the door body 1 to a certain extent, thereby improving the stability of the folding door, and the hinge 2 is installed on the end face of the horizontal profile 11 of the door body 1, so that it is not easily seen by people, thereby enhancing the simplicity and beauty of the surface of the folding door.
[0023] refer to Figure 3 The arc-shaped recess 211 located on the fixing plate 21 gradually narrows from front to back in the plugging direction. It should be noted that the two hinges 2 on the same door body 1 are symmetrically arranged. Figure 3 The bottom perspective view of the hinge 2 is shown in FIG. 2 , which can also be understood as the hinge 2 installed on the lower side of the door body 1 and the horizontal profile 11. Figure 4 It is a three-dimensional diagram of the top surface angle of the hinge 2, which can also be understood as the hinge 2 installed on the horizontal profile 11 on the upper side of the door body 1, so that when the fixing screw 23 enters the recess 211, the wide arc at the front end of the recess 211 is to facilitate the entry of the fixing screw 23. For this purpose, an insertion port corresponding to the recess 211 is provided on the end face of the fixing plate 21, and after the fixing screw 23 enters, the rear part is first pushed up to the notch of the slot 110. It is also possible to directly set a recess 211 with the same arc from front to back, which is more convenient for production.
[0024] In this embodiment, both of the fixed plates 21 are connected to an articulated arm 22, one of the articulated arms 22 is provided with a through hole 220, a washer 221 is provided on one side of the through hole 220, and the other articulated arm 22 is provided with a rotating shaft 222, the rotating shaft 222 is passed through the through hole 220 and riveted with the washer 221, further, the fixed plate 21 and the corresponding articulated arm 22 are integrally die-cast, further improving the overall strength of the hinge 2, and the die-casting hardness is relatively high, so the provision of a recess 211 is more conducive to screwing in the fixing screw 23, the fixed plate 21 and the articulated arm 22 are distributed in an L-shape, the through hole 220 is provided at one end of the articulated arm 22 away from the fixed plate 21; the other articulated arm 22, the rotating shaft 222 is provided at one end of the articulated arm 22 away from the fixed plate 21.
[0025] In this embodiment, the two fixing plates 21 are respectively inserted into the corresponding slots 110, and the ends of the horizontal profiles 11 are provided with a receiving space 111 for receiving the hinged arms 22. Figure 6-8 As shown, the two fixing plates 21 are completely hidden in the slots 110 of the horizontal profile 11, and the horizontal profile 11 is also provided with an accommodating space 111, so that the hinge arm 22 does not protrude from the horizontal profile 11. Only the ends of the two hinge arms 22 protrude from the horizontal profile 11 and are connected to each other, which better hides the hinge 2 and enhances the overall beauty of the folding door. On this basis, the door body 1 also includes a vertical profile 12, which is arranged between the two horizontal profiles 11. The vertical profile 12 is snap-connected with a cover plate 120 for covering the hinge 2. The height of the cover plate 120 corresponds to the total height of the door body 1, that is, when the cover plate 120 is snap-connected to the vertical profile 12, both ends protrude from the vertical profile 12, and the protruding parts just cover the end faces of the horizontal profile 11.
[0026] In this embodiment, the width of the fixing plate 21 is greater than the slot width of the slot 110, so that the fixing plate 21 cannot be separated from the slot 110. The fixing plate 21 is inserted through the end face of the slot 110. Specifically, the cross-sectional shape of the slot 110 is preferably T-shaped, that is, Figure 1 As shown in 2 , the groove is narrow at the top and wide at the bottom from the groove opening to the groove bottom. Preferably, the width of the fixing plate 21 corresponds to the maximum groove width of the slot 110 , so that the fixing plate 21 cannot be offset in the thickness direction of the horizontal profile 11 after being inserted into the slot 110 .
[0027] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
