Technical Field
[0001] This utility model relates to the field of magnetic door technology, specifically a magnetic door that is easy to install. Background Technology
[0002] A magnetic door is a type of door that uses magnetic force to achieve an automatic closing function. These doors typically have a magnetic device installed between the door frame and the door leaf. When the door approaches the door frame, the magnetic force will automatically attract the door and close it tightly. The design of the easy-to-install magnetic door aims to simplify the installation process, allowing users to easily complete the installation even without professional skills.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN217001460U) discloses a magnetic door that is easy to install. The door includes a door frame and a door leaf. A door handle is fixedly installed on the door leaf, which is rotatably mounted on the door frame. A window frame is fixedly installed on the door leaf, and tempered glass is fixedly installed inside the window frame. Door leaf frame material is fixedly installed on the outside of the door leaf, and aluminum material is provided inside the door leaf. Both the aluminum material and the door frame have slots for placing strong magnets, which are fixedly installed with strong magnets and positioning blocks. In this utility model, both the door frame and the door leaf are made of aluminum profiles with holes for installing strong magnets inside. This results in a more aesthetically pleasing design. The magnets are mechanically locked with screws, making them less prone to falling off. The overall structure is simple, compact, and aesthetically pleasing. Compared to traditional door closer designs, this design eliminates the need for a lock to close the door; instead, it uses strong magnets to open and close the door, reducing steps and increasing installation efficiency. Furthermore, it is more practical than installing a traditional door closer.
[0004] While the aforementioned patent, through its structural design, eliminates the need for a lock to close the door compared to traditional door closers, instead using a strong magnet to open and close it, thus reducing steps and increasing installation efficiency, and offering better practicality than traditional door closers, it is not convenient for quick installation of magnetic doors. Compared to some traditional door types, magnetic doors may require a more complex installation process, especially those models that rely on electromagnets. To ensure the effectiveness and stability of magnetic doors, it is usually necessary to fix the door frame and door leaf, including drilling, fixing screws, or installing brackets. This fixing method is not flexible enough when the door needs to be moved or its position changed frequently.
[0005] Therefore, this utility model provides a magnetic door that is easy to install, in order to solve the above problems. Utility Model Content

[0017] This utility model provides a magnetic door that is easy to install, such as... Figure 1 - Figure 4 As shown, the magnetic door that is easy to install includes a magnetic door 1. An installation mechanism is fixedly connected to one side of the magnetic door 1, a magnetic block is fixedly connected to the outer ring of the magnetic door 1, and a groove for fixing and installing the door or window is opened on the surface of the magnetic door 1. The installation mechanism includes mounting block A 2. One side of mounting block A 2 is connected to one side of the magnetic door 1 by bolts and threads. The other side of mounting block A 2 is fixedly connected to an arc plate 3. One end of the arc plate 3 is fixedly connected to a rotating rod 4. Through the cooperation of the installation mechanism and the reinforcement mechanism, using bolts and snap-fit, the magnetic door 1 can be quickly installed.

[0018] A rotating cylinder 5 is rotatably connected to the outer surface of the rotating rod 4. A B mounting block 6 is fixedly connected to one side of the rotating cylinder 5. A reinforcing mechanism is fixedly connected to one end of the B mounting block 6. The A mounting block 2 is installed on the magnetic door 1. Then the rotating cylinder 5 is sleeved on the rotating rod 4. Subsequently, the fixing plate 9 is sleeved on the connecting block 7 to fix the fixing plate 9 to the car. Then, the fixing bolt 8 is threaded onto the connecting block 7. Finally, the threaded sleeve 10 is screwed onto the fixing bolt 8.
[0019] The reinforcement mechanism includes a connecting block 7. A threaded hole is provided in the middle of the connecting block 7. A fixing plate 9 is threadedly connected to the inside of the threaded hole through a fixing bolt 8. A threaded sleeve 10 is threadedly connected to the outer surface of the fixing bolt 8. The threaded sleeve 10 has slots at both ends. A snap-fit rod 11 is inserted into the slot. The threaded sleeve 10 is screwed to the appropriate position, and the snap-fit rod 11 is inserted into the threaded sleeve 10 and then into the connecting block 7. After the snap-fit rod 11 is inserted into the connecting block 7, it presses the fixing block 13. The fixing block 13 presses the A spring 12. The A spring 12 extends and retracts inside the snap-fit rod 11. When the fixing block 13 enters the connecting block 7, the fixing block 13 automatically pops out through the A spring 12 and automatically snaps in place.
[0020] The outer surface of the snap-fit rod 11 has a hole for fixing the spring A 12. One end of the spring A 12 is fixedly connected to a fixing block 13. When the snap-fit rod 11 needs to be removed, the fixing block 13 is pressed into the snap-fit rod 11 by inserting an external plug into the round hole on the connecting block 7, and the snap-fit rod 11 is pulled out.
[0021] A square groove is provided in the middle of one side of the magnetic door 1. A rubber plate 14 is fixedly connected inside the square groove. A round hole is provided on one side of the rubber plate 14. A B spring 15 is fixedly connected inside the round hole. A compression rod 16 is fixedly connected to one end of the B spring 15. When the magnetic door 1 is closed, in order to increase the shock absorption effect, the magnetic door 1 compresses the rubber plate 14. The rubber plate 14 compresses the compression rod 16. The compression rod 16 compresses the arc-shaped rubber pad 17. The arc-shaped rubber pad 17 compresses the C spring 18 and the compression rod 16.
[0022] One end of the extrusion rod 16 is fixedly connected to an arc-shaped rubber pad 17, and the other side of the arc-shaped rubber pad 17 is fixedly connected to a C spring 18. One end of the C spring 18 is fixedly connected to one side of the rubber plate 14. The extrusion rod 16 presses against the B spring 15, which facilitates the arc-shaped rubber pad 17 to achieve a shock absorption effect.
[0023] Specifically, mounting block 2 (A) is installed on the magnetic door 1. Then, rotating cylinder 5 is fitted onto rotating rod 4. Next, fixing plate 9 is fitted onto connecting block 7, fixing plate 9 to the car. Then, fixing bolt 8 is threaded onto connecting block 7. Next, threaded sleeve 10 is screwed onto fixing bolt 8, adjusting the position of threaded sleeve 10. Clamping rod 11 is inserted into threaded sleeve 10 and then into connecting block 7. After clamping rod 11 is inserted into connecting block 7, it presses against fixing block 13. Fixing block 13 presses against spring A 12, which extends and retracts within clamping rod 11. When fixing block 13 enters connecting block 7, fixing block 13 automatically pops out via spring A 12. The fixing block 13 automatically engages. When the locking rod 11 needs to be removed, the fixing block 13 is pressed into the locking rod 11 by inserting the external rod into the round hole on the connecting block 7, and the locking rod 11 is pulled out. Then, when the magnetic door 1 rotates, the arc plate 3 rotates in the rotating cylinder 5 through the rotating rod 4, which facilitates the rotation of the magnetic door 1. Then, when the magnetic door 1 is closed, in order to increase the shock absorption effect, the magnetic door 1 squeezes the rubber plate 14. The rubber plate 14 squeezes the squeezing rod 16, the squeezing rod 16 squeezes the arc rubber pad 17, the arc rubber pad 17 squeezes the C spring 18 and the squeezing rod 16, and the squeezing rod 16 squeezes the B spring 15, which facilitates the arc rubber pad 17 to play a shock absorption role.
