[0021] Example

[0022] refer to Figures 1 to 4 The door magnetic switch structure of this embodiment includes a first housing 1 and a second housing 2. Guide rails 3 are installed on both sides of the interior of the first housing 1. A snap-fit ​​spring 4 is fixedly connected to one side of the first housing 1. A locking block 5 is fixedly connected to the end of the snap-fit ​​spring 4 away from the bottom of the first housing 1. A connecting plate 6 is fixedly connected to the side of the second housing 2 closest to the first housing 1. A door magnetic assembly 7 is installed between the second housing 2 and the connecting plate 6. A slot 8 is formed on the side of the connecting plate 6 closest to the locking block 5. The end of the locking block 5 is inserted into the inner side of the slot 8. A slot 11 is formed on the side of the first housing 1 away from the second housing 2. The slot 11 is located at the lower outer end of the snap-fit ​​spring 4. The guide rails 3 on both sides inside the second housing 2 provide accurate guidance for the insertion of the connecting plate 6, ensuring that the installation process is precise and efficient. When the connecting plate 6 is inserted into the first housing 1, the snap-fit ​​block 5 can automatically engage with the slot 8 to achieve a fast and stable connection, which greatly improves the installation efficiency. At the same time, this connection method also ensures the stability of the door magnetic structure during use. The slot 11 is also thoughtfully designed. When disassembly is required, the bottom of the snap-fit ​​block 5 can be easily squeezed with a pin or small steel nail to disengage the snap-fit ​​block 5 from the slot 8, achieving quick disassembly.

[0023] refer to Figures 1-2 and Figure 4 The first housing 1 has support plates 9 fixedly connected to both ends, and support blocks 10 fixedly connected to both sides of the bottom of the connecting plate 6. The inner side of the support blocks 10 is fitted to the support plates 9. The two sides of the connecting plate 6 are inserted into the guide rail 3. The side of the first housing 1 is set in a right trapezoidal shape. The support plates 9 at both ends of the first housing 1 provide auxiliary support for the connecting plate 6, which enhances the stability of the overall structure. The support blocks 10 on both sides of the bottom of the connecting plate 6 are fitted to the support plates 9, which further strengthens the connection effect, making the first housing 1 and the second housing 2 more robust and reliable when used together. The two sides of the connecting plate 6 are inserted into the guide rail 3, which ensures accurate positioning during installation and use, prevents problems such as offset, and improves the working accuracy of the door magnetic switch.

[0024] refer to Figures 1-4 Mounting blocks 12 are fixedly connected to both sides of the bottom of the first housing 1. The side of the mounting block 12 is also set in a right trapezoidal shape. Mounting holes 13 are opened on both sides of the lower end of the mounting block 12. The mounting holes 13 are countersunk holes. The right trapezoidal shape of the side of the mounting block 12 can better withstand the pressure and external force from above. The mounting holes 13 on both sides of the lower end of the mounting block 12 are countersunk holes. This design allows the head of the fixing screw to be recessed into the hole during installation, making the mounting surface of the door magnetic switch flatter, reducing the risk of collision or scratch caused by the protruding screw, and making the installation more stable, thus improving the safety and reliability of the door magnetic switch during use.

[0025] refer to Figures 1-3 The upper end of the first housing 1 is threaded with mounting screws 14 on both sides. The door magnetic component 7 is installed on the first housing 1 by mounting screws 14. The side of the card block 5 is set in a right-angled triangle shape. The inclined surface of the card block 5 is set on the side close to the connecting plate 6. The mounting screws 14 on both sides of the upper end of the first housing 1 are used to install the door magnetic component 7. The threaded connection method makes the installation firm and reliable, and facilitates the disassembly and replacement of the door magnetic component 7, improving the convenience of maintenance. The side of the card block 5 is set in a right-angled triangle shape, and its inclined surface is close to the connecting plate 6. In this way, when the connecting plate 6 is inserted into the first housing 1, the connecting plate 6 can smoothly squeeze the inclined surface of the card block 5, so that the card block 5 is automatically pressed to one side and abuts against the locking spring 4 for limiting. When the connecting plate 6 is fully inserted, the locking spring 4 resets and drives the card block 5 to insert into the card slot 8. This design makes the installation process smoother and more efficient. At the same time, the shape of the right-angled triangle also ensures the stability and firmness of the card block 5 when it is engaged with the card slot 8.

[0026] Operating principle and advantages: By setting up a first housing 1 and a second housing 2, the door magnetic component 7 can be installed inside the second housing 2 using the mounting screw 14. After the door magnetic component 7 is installed, the connecting plate 6 on the second housing is inserted between the guide rails 3 of the second housing 2. When the connecting plate 6 contacts the inside of the second housing 2, it will press against the top inclined surface of the locking block 5. After being pressed, the locking block 5 will abut against the locking spring 4 and be limited by it. When the connecting plate 6 is fully inserted into the first housing 1, the locking block 5 and the locking groove 8 will contact each other. At this time, the locking spring 4 will reset and drive the locking block 5 to be inserted into the locking groove 8. Through the mutual limiting of the locking block 5 and the locking groove 8, the first housing 1 and the second housing 2 can be quickly locked and installed, so that the device can be quickly assembled and installed during use.

[0027] By setting the slot 11, when it is necessary to disassemble the magnetic door assembly 7, a pin or some small steel nails can be taken out and inserted into the slot. At this time, the bottom of the locking block 5 is pressed by the pin or steel nail, causing the locking block 5 to move upward and deform the locking spring 4. After the locking spring 4 is deformed, the locking block 5 can be separated from the inside of the slot 8. After the locking block 5 and the slot 8 are separated from each other, the first housing 1 and the second housing 2 can be separated, and then the connecting plate 6 can be pulled out from the inside of the guide rail 3, which facilitates quick disassembly and assembly of the magnetic door structure. After installation, the connecting plate 6 can be reinforced by the support plate 9. At the same time, the support block 10 and the support plate 9 are in contact with each other, which can further support and reinforce the connection between the first housing 1 and the second housing 2, making it easy to quickly disassemble the first housing 1 and the second housing 2 of the magnetic door structure. At the same time, the first housing 1 and the second housing 2 can have good stability.
