Technical Field

[0001] This utility model relates to the technical field of folding door hardware accessories, specifically a side-folding door panel hanging device. Background Technology

[0002] Traditional suspended folding door panels often employ a method of placing a load in the middle of the folding door to reduce the stress on the suspension components. This prevents the center of gravity from shifting during the folding door's movement. In this design, the connection points are located on both sides of the folding door, requiring hinges for secure fastening. Therefore, there are many hardware components and numerous production processes involved. Furthermore, when the folding door panel thickness is between 18 and 25 mm, the requirements for the dimensions and tightness of the hardware are even higher.

[0003] Therefore, we propose a side-folding door panel hanging device to solve the problems mentioned above. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 This utility model provides a technical solution: a side-folding door panel suspension device, including: a door panel 1, a guide component 2, and a hinge body 3. Several door panels 1 are provided. The ends of two adjacent door panels 1 are connected in series by the hinge body 3. The hinge body 3 is fixedly installed at the top and bottom of the door panel 1. The non-adjacent ends of the door panel 1 are fixedly installed with suspension metal strips 4. After the door panel 1 is folded, the hinge body 3 and the suspension metal strips 4 at the top of the same side are connected to the guide component 2, so that the door panel 1 is suspended below the guide component 2. The cooperation of the guide component 2 makes the door panel 1 form a straight line after unfolding.

[0016] Hinge slots 11 and suspension extension holes 12 are provided at the top and bottom edges of the door panel 1. The suspension extension holes 12 are located inside the hinge slots 11. The hinge slots 11 are used for embedded installation of the hinge body 3 and the suspension metal strip 4. The suspension extension holes 12 are used for the guide assembly 2 to pass through the hinge body 3 and the suspension metal strip 4 and then be inserted into the door panel 1 to achieve further connection and fixation between the guide assembly 2 and the door panel 1.

[0017] The guide assembly 2 includes a guide rail 21. A fixing block 22 is provided at the inner end of the guide rail 21. Several moving blocks 24 are slidably arranged inside the guide rail 21. The total number of fixing blocks 22 and moving blocks 24 corresponds to the door panel 1. The fixing block 22 is located above the starting door panel 1. Both the fixing block 22 and the moving blocks 24 are rotated to suspend the suspension assembly 23. The suspension assembly 23 includes a suspension shaft 231 and a limiting nut 232. The suspension shaft 231 is fixedly inserted into the suspension extension hole 12 of the door panel 1 after passing through the hinge body 3 or the suspension metal insert 4, so as to realize the integral fixed connection of the suspension shaft 231, the hinge body 3 or the suspension metal insert 4 and the door panel 1. The limiting nut 232 is threaded on the suspension shaft 231. The limiting nut 232 is used to lock the suspension shaft 231 to the hinge body 3 or the suspension metal insert 4.

[0018] Four pulleys 25 are mounted on the side of the movable block 24, and the pulleys 25 are tactilely connected to the guide rail 21.

[0019] The hinge body 3 includes a first hinge component 31 and a second hinge component 32, which are hinged together. The first hinge assembly 31 is mainly composed of a first extension strip 311 and a first trapezoidal bridge plate 312 fixedly connected. The first extension strip 311 is inserted into the hinge slot 11 and fixed to the door plate 1 by screws. The second hinge assembly 32 is mainly composed of a second extension bar 321 and a second trapezoidal bridge plate 322 fixedly connected. The second extension bar 321 is inserted into the hinge slot 11 and fixed to the door plate 1 by screws. The first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322 are hinged together by a pivot. The first trapezoidal bridge plate 312 is equipped with a pivot anti-loosening screw 35 for locking the pivot. The hinged surfaces of the first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322 are respectively provided with a first limiting plane 313 and a second limiting plane 323. When the first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322 rotate relative to each other to the same straight line, the first limiting plane 313 and the second limiting plane 323 touch each other, limiting the relative angle between the first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322. Anti-collision rubber 33 is fixedly installed on the other mating surface of the first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322. It is used to prevent the first trapezoidal bridge plate 312 and the second trapezoidal bridge plate 322 from colliding when they rotate relative to each other to be parallel, thereby improving the service life of the hinge body 3.

[0020] The first extension bar 311 and the second extension bar 321 have suspension holes 34 at the corresponding suspension extension holes 12. The suspension holes 34 are threaded holes. The suspension shaft 231 is screwed into the suspension holes 34 to achieve the fixed assembly of the suspension shaft 231 and the hinge body 3.

[0021] Working principle: After the hinge body 3 is unfolded, the door panel 1 can be unfolded into a plane. After the hinge body 3 is folded, the door panel 1 can be folded up and placed on the side of the threshold. According to the position of the door panel 1, the suspension shaft 231 is connected to the odd-numbered hinge body 3, and the suspension shaft 231 is rotated and suspended on the moving block 24 so that the door panel 1 can be erected vertically under the threshold. As the moving block 24 moves, the door panel 1 can be folded and unfolded. Door panel 1 can be configured to fold outwards or inwards as needed. After one side is folded, the other side is not restricted by door panel 1, thus preventing door panel 1 from taking up space.
