Traditional door magnetic switch faces some challenges in practical application. On the one hand, the sealing performance of ordinary door magnetic switch is often insufficient, when the door is in different environments, dust, water vapor and the like can easily invade the inside, affecting its normal work and service life. On the other hand, the existing door magnetic switch may not be tight or stable in cooperation with the installation of the door, leading to unstable signal transmission or easy misjudgment. In addition, for some special environment requirements of high places, such as humid, dusty environment, traditional door magnetic switch may be difficult to meet the demand of long-term reliable operation, therefore we put forward a kind of door magnetic switch sealing structure.

The structure design of the patent makes the door magnetic switch more stable in the process of installation and use, and has certain anti-interference and prolongs the life effect.

[0004] However, the above-mentioned patent improves the installation convenience and shock absorption and buffering capacity when using, but its sealing performance still needs to be improved. Especially in humid, dusty and other complex environments, the sealing structure of the patent may be difficult to keep the inside of the door magnetic switch dry and clean for a long time, thereby increasing the risk of failure. In addition, the stability and reliability of the magnetic attraction structure of the patent need to be further strengthened to ensure the accuracy and reliability of door state detection.

[0005] Therefore, a door magnetic switch sealing structure is proposed, which significantly improves the sealing performance by adopting unique sawtooth sealing ring and protective sealing ring design, and ensures the long-term stable operation and accurate detection of the door magnetic switch in various environments by combining stable and reliable magnetic attraction structure.

[0017] Compared with the prior art, the present invention provides a door magnetic switch sealing structure, which has the following beneficial effects:

[0018] 1. This door magnetic switch's sealing structure boasts excellent sealing performance. The unique serrated design of the serrated sealing ring ensures a tight fit, maintaining a seal even under pressure and friction during door opening and closing, preventing the intrusion of dust, moisture, and other contaminants. Combined with the protective sealing ring, the waterproof gasket at the connection enhances waterproofing capabilities and reduces the risk of malfunction. The wavy structure of the protective sealing ring provides good elasticity and adaptability, while the staggered connecting grooves on both sides improve sealing reliability. It maintains excellent sealing performance even in complex scenarios, ensuring long-term stable system operation and providing users with a reliable solution.

[0026] 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.

[0027] Please see Figures 1-5 A door magnetic switch sealing structure includes a switch housing 1, a permanent magnet 4, and a serrated sealing ring 6. The switch housing 1 has two sets of battery boxes 2 inside, a signal transceiver 3 inside the battery box 2, a permanent magnet 4 on one side of the signal transceiver 3, two sets of adsorption magnets 5 on the right side of the switch housing 1, a serrated sealing ring 6 on the outer side of the right side of the switch housing 1 away from the adsorption magnets 5, a protective sealing ring 7 on the outer side of the serrated sealing ring 6, and a quick-release cover 8 on the front of the switch housing 1.

[0028] Multiple sets of mounting holes are provided at equal intervals on one side of the switch housing 1, and the inside of the mounting holes adopts a threaded structure.

[0029] The top of the battery box 2 is equipped with a protective pad made of rubber.

[0030] The signal transmitter 3 has two sets of signal transmitting rods on both sides of its top, which extend to the outside of the switch housing 1.

[0031] One end of the permanent magnet 4 extends to the right side of the switch housing 1 and connects to the adsorption magnet 5.

[0032] The outer side of the serrated sealing ring 6 is entirely serrated, and a waterproof gasket is provided at the connection between the serrated sealing ring 6 and the protective sealing ring 7.

[0033] The protective sealing ring 7 adopts a wave-shaped structure, and there are interlocking connecting grooves on both sides of the protective sealing ring 7.

[0034] Working principle: When the door is closed, the two sets of magnets 5 on the right side of the switch housing 1 attract each other, keeping the entire structure stable. At this time, the signal transceiver 3 is in normal working condition, communicating with external devices through the signal transceiver rods on both sides of its top. When the door is opened, the position of the switch housing 1 changes due to the separation of the magnets 5. During this process, the serrated structure of the serrated sealing ring 6 cooperates with the protective sealing ring 7 to provide a good seal, preventing dust, moisture, etc. from entering the interior. The battery in the battery box 2 provides energy for the entire system. The protective pad protects the battery box and reduces the impact of external impacts on the battery. The signal transceiver 3 sends out the detected door status information through the signal transceiver rods so that relevant devices can process and control it accordingly.
