Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1
[0020] like Figure 1-3 As shown in the figure, a multi-fold door that is easy to open includes a bracket 1, which is characterized in that: a baffle 2 is fixed on the top of the bracket 1, a motor 3 is fixed on the top of one side of the bracket 1, the output end of the motor 3 is connected to a first rotary wheel 4, the outer side of the first rotary wheel 4 is coaxially connected to a transmission rod 5, a pull rope 6 is wrapped around the outer side of the first rotary wheel 4, a second rotary wheel 7 is installed on the inner wall of the bracket 1, a third rotary wheel 8 is arranged parallel to one side of the second rotary wheel 7, a middle door assembly is installed on the inner side of the bracket 1, the top of the middle door assembly is rotatably connected to the upper door assembly, the bottom of the middle door assembly is rotatably connected to the lower door assembly, a first guide rail 15 is provided on the inner wall of the bracket 1, a guide block 16 is fixedly provided below the first guide rail 15, and a second guide rail 17 is provided on one side of the guide block 16.
[0021] The pull rope 6 forms a winding mechanism between the first rotating wheel 4 and the bracket 1, and the pull rope 6 is connected in series with the first rotating wheel 4, the second rotating wheel 7 and the third rotating wheel 8, and the final end is fixed to the bottom side of the middle door assembly, ensuring that the overall engagement operation of the electric control equipment can be stable and the use is stable and flexible.
[0022] The middle door assembly includes a middle door panel 9, and first guide wheels 10 are symmetrically arranged at the bottom ends of both sides of the middle door panel 9. A second guide wheel 11 is arranged below the first guide wheel 10. The first guide wheel 10 slides along the sliding groove between the second guide rail 17 and the guide block 16 to ensure that the middle door panel 9 can be stably opened and closed, and facilitate the synchronous movement of the top and bottom door panels.
[0023] The upper door assembly includes an upper door panel 12, and third guide wheels 13 are symmetrically installed on the bottom ends of both sides of the upper door panel 12, and fourth guide wheels 14 are symmetrically arranged on the top ends of both sides of the upper door panel 12. The fourth guide wheel 14 is set to slide along the inner side of the first guide rail 15, and the third guide wheel 13 is set to slide along the rear side of the guide block 16, so that the upper door panel 12 can follow the adjustment to perform stable sliding control opening and closing.
[0024] The lower door assembly includes a lower door panel 18, and fifth guide wheels 19 are symmetrically provided at the bottom ends of both sides of the lower door panel 18. The fifth guide wheels 19 are slidingly provided along the inner side of the bracket 1 to stabilize the lower door panel 18 so that it can stably adjust the movement when folding inward.
[0025] Two groups of brackets 1 are symmetrically arranged about the central axis of the baffle 2. Combined with multiple groups of guide wheels, the three door panels between the two groups of brackets 1 can be stably controlled to fold, lift, open and close stably, ensuring stable and convenient use.
[0026] Working principle: First, through the setting of multiple sets of wheels, the equipment can be adjusted stably, and the control motor 3 drives the first wheel 4 to rotate to perform the retraction and extension operation of the outer pull rope 6, and the second wheel 7 and the third wheel 8 are used to relay the pull rope 6 to improve the overall stability of use, and flexibly control the opening and closing adjustment of the door group. With the setting of multiple sets of guide wheels, the three door panels between the two sets of brackets 1 can be stably controlled to perform stable folding, lifting, opening and closing, ensuring stable and convenient use.
[0027] Then, the entire middle door assembly, the upper door assembly and the lower door assembly are connected and transmitted through rotation. When the pull rope 6 is retracted and pulled, the entire middle door assembly can be stably pulled up and down to adjust the height, thereby transmitting the upper door assembly and the lower door assembly at the top and bottom to follow the opening and closing control adjustment, which is convenient to use and operate, and has multiple folding settings, which better reduces the size of the door panel and effectively saves the space occupied by opening and closing, making the opening and closing more flexible, convenient and stable.
