Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] Example 1 like Figures 1 to 4 As shown, a door and window structure is used for installation in office buildings, factories, etc., and the folding opening and closing is controlled by "automation". The door and window structure includes a door and window frame 1 for installation in the door and window openings, and folding door and window unit structures that can be symmetrically installed in the door and window openings of the door and window frame 1. The folding door and window unit structure includes a first folding door and window panel 2 and a second folding door and window panel 3, which are foldably connected by several hinges. A top guide beam 11 is installed and connected to the top of the door and window opening of the door and window frame 1, and the top of the first folding door and window panel 2 and the second folding door and window panel 3 are foldably and movably connected to the top guide beam 11. A bottom guide beam 12 is installed and connected to the bottom of the door and window opening of the door and window frame 1, and the bottom of the first folding door and window panel 2 and the second folding door and window panel 3 are foldably and movably connected to the bottom guide beam 12.
[0015] In this embodiment, after the door and window frame 1 is installed and fixed at the designed door and window opening, the symmetrically installed and foldable folding door and window unit structure is "folded" and installed on the door and window frame 1. The door and window opening is "opened" or "closed" by controlling and adjusting the first folding door and window plate 2 and the second folding door and window plate 3 of the folding door and window unit structure to "fold" or "unfold".
[0016] Example 2 Based on Embodiment 1, the first folding door and window panel 2 is located on the side wall of the door and window opening away from the door and window frame 1; the top of the first folding door and window panel 2 is connected to a first top door and window roller mounting seat 21, and the two sides of the first top door and window roller mounting seat 21 away from the first folding door and window panel 2 are respectively connected to the first top door and window rollers 211 via pivots; the top guide beam 11 has a top limiting guide rail groove, and the first top door and window rollers 211 are installed in the top limiting guide rail groove for rolling limitation. The bottom of the first folding door and window panel 2 is connected to a first bottom door and window roller mounting seat 22, and the two sides of the first bottom door and window roller mounting seat 22 away from the first folding door and window panel 2 are respectively connected to the first bottom door and window rollers 221 via pivots; the bottom guide beam 12 has a bottom limiting guide rail groove, and the first bottom door and window rollers 221 are installed in the bottom limiting guide rail groove for rolling limitation. The first movable sliding seat 23 is connected to the bottom roller mounting seat 22 of the first door and window near the side of the door and window frame 1 via a connecting plate. The first movable sliding seat 23 is movably mounted on the ball screw 4, which drives the first movable sliding seat 23 to move relative to the ball screw 4.
[0017] In this embodiment, by controlling the rotation of the ball screw 4, the first movable sliding seat 23 is driven to move horizontally relative to the ball screw 4 along the "axis line"; the first folding door and window panel 2 is driven to rotate and fold around the second folding door and window panel by means of the hinge under the "rolling limit" action of the first top door and window roller 211 and the first bottom door and window roller 221.
[0018] Example 3 Furthermore, the second folding door / window panel 3 is located on the side wall of the door / window opening near the door / window frame 1; the top of the second folding door / window panel 3 is connected to a second door / window top roller mounting seat 31, and the two sides of the second door / window top roller mounting seat 31 away from the second folding door / window panel 3 are respectively connected to top door / window rollers 311 via pivots; the top door / window rollers 311 are installed in the top limiting guide rail groove opened in the top guide beam 11 for rolling limitation. The bottom of the second folding door / window panel 3 is connected to a second door / window bottom roller mounting seat 32, and the two sides of the second door / window bottom roller mounting seat 32 away from the second folding door / window panel 3 are respectively connected to second bottom door / window rollers 321 via pivots; the second bottom door / window rollers 321 are installed in the bottom limiting guide rail groove opened in the bottom guide beam 12 for rolling limitation.
[0019] Furthermore, a second movable sliding seat 33 is connected to the side of the bottom roller mounting base 32 of the second door and window near the door and window frame 1 via a connecting plate. The second movable sliding seat 33 is movably limited and passes through the ball screw 4. A limit mounting seat 41 is provided at one end of the ball screw 4, and the ball screw 4 is rotatably connected to the limit mounting seat 41 via a bearing. The limit mounting seat 41 is fixedly connected to the bottom guide beam 12 by bolts. The other end of the ball screw 4 passes through the fixed seat 42 via a bearing and its end is connected to the output end of the screw mechanism. The housing of the screw mechanism is fixedly connected to the end of the bottom guide beam 12 away from the limit mounting seat 41 by bolts (the screw mechanism is not shown in the attached drawings). The fixed seat 42 is fixedly connected to the bottom guide beam 12 by bolts.
[0020] In this embodiment, by controlling the screw mechanism to drive the ball screw 4 to rotate between the "two folding door and window unit structures" and the door and window frame 1, the ball screw 4 drives the first folding door and window panel 2 of the folding door and window unit structure to rotate and be limited by the hinge with the second folding door and window panel 3, and the second folding door and window panel 3 to be "rotationally limited" around the ball screw 4 (the second folding door and window panel 3 is rotated and limited by the fixed seat 42 with the ball screw 4, that is, the second folding door and window panel 3 rotates around the ball screw 4 through the fixed seat 42, but cannot move horizontally relative to the ball screw 4 along the "axis line" direction). Furthermore, the two first folding door and window panels 2 rotate in opposite directions to the first movable sliding seat 23 of the ball screw 4. That is, when the ball screw 4 rotates, the two first folding door and window panels 2 move relative to each other when the first movable sliding seat 23 moves relative to each other, thereby realizing the "unfolding" or "folding" of the second folding door and window panels 3 connected to them, thus achieving "automation" to control the folding opening and closing of the door and window structure.
