Description

Technical Field

[0001] This utility model relates to the field of sliding folding door technology, and in particular to a sliding folding door with a quick-fixing structure. Background Technology

[0002] Sliding folding doors are widely used in the construction, industrial, and smart home fields due to their high space utilization and flexible opening and closing. They also offer a variety of colors, materials, and surface treatments, allowing for customization to match different interior design styles. They can also function as screens or decorative walls. Furthermore, the installation of sliding folding door tracks does not damage the floor, making them suitable for complex spatial layouts. They also have low maintenance costs over the long term, making them ideal for projects with limited budgets.

[0003] However, existing technologies still have significant limitations. The installation of traditional sliding doors requires precise measurement and adjustment, especially the flatness of the track and the balance of the door leaf. If the installation is not done properly, the door panel may fall off and break when the sliding door is used later, which poses a great safety hazard. Improper installation also makes the folding door look unsightly. The design of the cooperation between traditional fixed components and door tracks and hinges is more complicated, requiring more materials and labor for installation, which increases production costs.

[0004] Therefore, to address the issues of complex installation, easy detachment, and high maintenance and production costs associated with the aforementioned sliding folding doors, a sliding folding door with a quick-fixing structure that utilizes multiple limiting points and multiple locking mechanisms can be designed to solve these problems.

[0006] The technical solution of this utility model is as follows: a push-pull folding door with a quick-fixing structure, including a door panel; and an upper slide rail, with the upper slide rail fixedly connected above the door panel, and several door panels are provided. Several door panels are evenly distributed below the upper slide rail. Two connecting brackets are bolted to the upper part of the door panel. A fixed shaft is fixedly connected to the upper part of the connecting brackets. A lower roller is rotatably connected to the lower end of the fixed shaft. An upper roller is rotatably connected to the upper end of the fixed shaft. A damping spring is fixedly connected to the upper part of the fixed shaft. A first locking block is fixedly connected to the upper part of the damping spring. A locking groove is slidably connected to the upper part of the first locking block, and several locking grooves are provided. Several locking grooves are evenly distributed inside the upper slide rail.

[0007] Preferably, the upper slide rail is installed above the wall where the sliding folding door needs to be installed. Then, a fixed shaft is installed above the connecting frame. First, a lower roller is installed on the fixed shaft, and then an upper roller is installed above the lower roller. A damping spring is then connected to the top of the fixed shaft, and a first locking block is connected above the damping spring. The locking groove can limit the first locking block. All the installed connecting frames are then inserted into the upper slide rail. The connection frames are tested to see if they can slide normally and have multiple limiting points. Then, the door panel is connected through two installed connecting frames. The door panel and the upper slide rail are tested to see if they slide normally. After there are no problems, the remaining door panels are installed in the same way. After installation, the user only needs to push the door panel to achieve folding and extension of the door panel.

[0008] Preferably, the upper slide rail is fastened with two support plates, and a lower roller is slidably connected above the support plates. The fixed shaft is located between the two support plates, and a rotating bolt is provided below the support plates. The fixed shaft is rotatably connected to the rotating bolt.

[0009] Preferably, two second limiting plates are provided above the support plate, and the two second limiting plates are located between the lower roller and the upper roller.

[0010] Preferably, two storage slots are fixedly connected to both sides of the upper slide, and an installation base is fixedly connected to the inside of the storage slot. A limit column is fixedly connected to one side of the installation base, a limit block is fixedly connected to one side of the limit column, and a sliding block is slidably connected to the outside of the limit column.

[0011] Preferably, the door panel has a groove on the side near the storage slot, and two return springs are symmetrically fixedly connected inside the groove, with a second locking block fixedly connected to one side of the return spring.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a push-pull folding door with a quick-fixing structure, comprising a door panel 1; and an upper slide rail 2. The upper slide rail 2 is fixedly connected to the top of the door panel 1, and several door panels 1 are provided. Several door panels 1 are evenly distributed below the upper slide rail 2. Two connecting brackets 5 are bolted to the top of the door panel 1. A fixed shaft 6 is fixedly connected to the top of the connecting brackets 5. A lower roller 7 is rotatably connected to the lower end of the fixed shaft 6, and an upper roller 8 is rotatably connected to the upper end of the fixed shaft 6. A damping spring is fixedly connected to the top of the fixed shaft 6. 9. A first locking block 10 is fixedly connected above the damping spring 9. A locking groove 203 is slidably connected above the first locking block 10, and several locking grooves 203 are provided. The several locking grooves 203 are evenly distributed inside the upper slide rail 2. The upper slide rail 2 is installed above the wall where the sliding folding door needs to be installed. Then, a fixed shaft 6 is installed above the connecting frame 5. A lower roller 7 is first installed on the fixed shaft 6, and then an upper roller 8 is installed above the lower roller 7. The damping spring 9 is then connected to the top of the fixed shaft 6. The first locking block 10 is connected above the damping spring 9. The locking groove 203 can engage with the first locking block 10. To limit the movement, insert all the installed connecting brackets 5 into the upper slide rail 2. Then test whether the connecting brackets 5 can slide normally and perform multi-point limiting. Next, connect the door panel 1 through two installed connecting brackets 5 and test the normal sliding of the door panel 1 and the upper slide rail 2. After confirming that there are no problems, install all the remaining door panels 1 in the same way. After installation, the user only needs to push the door panel 1 to achieve folding and extension. There are two support plates 201 securely connected inside the upper slide rail 2. The lower roller 7 is slidably connected above the support plate 201, and the fixed shaft 6 is located at position 6. Between two support plates 201, a rotating bolt 11 is provided below the support plate 201. The fixed shaft 6 is rotatably connected to the rotating bolt 11. The lower roller 7 is placed on the two support plates 201. Through the connection of the rotating bolt 11 and the fixed shaft 6, the height of the door panel 1 is precisely controlled and the door panel 1 is adjusted to a suitable height. Two second limiting plates 202 are provided above the support plate 201. The two second limiting plates 202 are located between the lower roller 7 and the upper roller 8, so that the roller 7 and the upper roller 8 slide between the second limiting plates 202, ensuring that the movement of the door panel 1 is uniform and will not deviate.

[0024] Please see Figures 1-5In this embodiment, two storage slots 3 are fixedly connected to both sides of the upper slide rail 2. A mounting base 12 is fixedly connected to the inner side of each storage slot 3. A limiting column 13 is fixedly connected to one side of the mounting base 12, and a limiting block 15 is fixedly connected to one side of the limiting column 13. A sliding block 14 is slidably connected to the outer periphery of the limiting column 13. The two storage slots 3 are installed on both sides of the upper slide rail 2, concealing the retractable door panel 1. The mounting base 12 is connected to the inner side of the storage slots 3, and the limiting column 13 is connected to the mounting base 12. The limiting block 15 at the top of the limiting column 13 self-locks the door panel 1, fixing it in place. The locked door panel 1 can be easily opened using the sliding block 14 on the limiting column 13. A groove 103 is provided on the side of the door panel 1 near the storage slots 3. Two return springs 16 are symmetrically fixedly connected to the inner side of the groove 103. A second locking block 17 is fixedly connected to one side of each return spring 16. Two return springs 16 and a second locking block 17 are symmetrically installed on the groove 103 of the door panel 1. When the second locking block 17 is engaged in self-locking, it pushes the second locking block 17 on the door panel 1 onto the limiting block 15. The return spring 16 first compresses and then extends, and the second locking block 17 is locked between the sliding block 14 and the limiting block 15. When unlocking is required, pressure is applied to the door panel 1, causing the return spring 16 to compress and move the second locking block 17 behind the sliding block 14. Then, the door panel 1 is pulled, causing the second locking block 17 to slide out directly, completing the unlocking. A sliding track 4 is fixedly connected to the bottom of the door panel 1. A handle 101 is provided on the outer side of the door panel 1, and a sliding track 4 is provided below the door panel 1 to limit and stabilize the movement of the door panel 1. The handle 101 is provided on the door panel 1 to provide a point of force for pushing and pulling. A sliding groove 401 is provided on the sliding track 4. A first limiting plate 102 is fastened to the bottom of the door panel 1. The sliding groove 401 is slidably connected below the first limiting plate 102. The first limiting plate 102 below the door panel 1 is locked in the sliding groove 401, allowing the door panel 1 to slide in the sliding groove 401.

[0025] During operation, the upper slide rail 2 is installed above the wall where the sliding folding door will be installed. Then, a fixed shaft 6 is installed above the connecting frame 5. A lower roller 7 is first installed on the fixed shaft 6, followed by an upper roller 8 above the lower roller 7. A damping spring 9 is then connected to the top of the fixed shaft 6, and a first locking block 10 is connected above the damping spring 9. The locking groove 203 can limit the movement of the first locking block 10. The entire connected frame 5 is then inserted into the upper slide rail 2. The lower roller 7 is placed on the support plate 201, and the second limiting plate 202 is placed between the lower roller 7 and the upper roller 8. The height of the door panel 1 is controlled by rotating the bolt 11 and connecting it to the fixed shaft 6. The door panel 1 is adjusted to a suitable height, and then the normal sliding and multi-point limiting of the connecting frame 5 are tested. The door panel 1 is then connected to the two installed connecting frames 5, and the door panel 1 and the upper slide rail 2 are tested for normal sliding. No problems are found. Next, the first limiting plate 102 below the door panel 1 is inserted into the sliding groove 401, allowing the door panel 1 to slide within the sliding groove 401. This process is repeated for all remaining door panels 1. After installation, the user only needs to push the handle 101 on the door panel 1 to fold and extend it. When the door panels 1 are folded, they are stacked in the storage groove 3. When the door panel 1 is compressed into the storage groove 3, and the door panel 1 self-locks, the second locking block 17 on the door panel 1 is pushed onto the limiting block 15. The return spring 16 is compressed and then extended, and the second locking block 17 is locked between the sliding block 14 and the limiting block 15. When the door panel 1 needs to be unlocked, a small amount of pressure is applied to the door panel 1 to compress the return spring 16, causing the second locking block 17 to move behind the sliding block 14. Then, the door panel 1 is pulled, causing the second locking block 17 to slide out directly, completing the unlocking process and achieving rapid fixing of the push-pull folding door.

[0026] Through the above steps, the damping spring 9, the first locking block 10, and multiple locking slots 203 work together to enable the door panel 1 to be quickly fixed at multiple points during sliding without affecting the normal sliding of the door panel 1. Moreover, these components are simple to install and have low maintenance costs. The lower roller 7 and the upper roller 8 work together with the second limiting plate 202 to make the door panel 1 evenly stressed during sliding, so that the movement of the door panel 1 will not deviate and is not easy to jam. A self-locking device is also set inside the storage slot 3 to quickly fix the folded door panel 1 inside the storage slot 3, preventing the door panel 1 from sliding out on its own and causing inconvenience to people, while maintaining aesthetics. This solves the problems of complicated installation, easy detachment, and high maintenance and production costs of push-pull folding doors.
