[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a dustproof and waterproof outdoor door lock, including an outdoor door lock shell 1 and a side fixing block 3. An infrared sensing mechanism 2 is fixedly installed on the front of the outer wall of the outdoor door lock shell 1. The infrared sensing mechanism 2 includes a fixing cover 201, a refracting plate 202 and an infrared sensor 203. The fixing cover 201 is welded to the front of the outer wall of the outdoor door lock shell 1. The refracting plate 202 is welded to the inner wall of the fixing cover 201. The infrared sensor 203 is connected and installed at the rear of the outer wall of the fixing cover 201. When unlocking, the rays generated by the infrared sensor 203 can be refracted from the refracting plate 202, thereby sensing the position of the hand unlocking. The infrared sensor 203 is electrically connected to the drive motor 401, so that feedback can be sent to the drive motor 401.

[0022] Side fixing blocks 3 are fixedly installed on both sides of the outer wall of the outdoor door lock housing 1. An automatic door opening mechanism 4 is fixedly installed on one side of the inner wall of the side fixing block 3. The automatic door opening mechanism 4 includes a drive motor 401, a rotating shaft 402, a gear block 403, a connecting shaft 404, a gear plate 405, and a side door 406. The drive motor 401 is fixedly installed behind the outer wall of the side fixing block 3. The output end of the drive motor 401 is provided with a rotating shaft 402. The outer surface of the rotating shaft 402 is provided with a gear block 403 of matching size. The connecting shaft 404 is movably connected to one side of the inner wall of the side fixing block 3. A gear plate 405 is welded and installed on the lower side of the outer wall of the connecting shaft 404. The side door 406 is fixedly installed on one side of the outer wall of the gear plate 405. When the drive motor 401 is opened, the automatic door opening mechanism 406 is opened. The power supply of 1 drives the gear block 403 mounted on the outer wall of the rotating shaft 402 to rotate. The gear block 403 meshes with the gear plate 405, which allows the gear plate 405 to move left and right. At the same time, the connecting shaft 404 is limited by the inner wall of the side fixing block 3, which can stably adjust the position of the gear plate 405 and drive the gear plate 405 to open to the front of the outdoor door lock housing 1. The gear plate 405 forms a sliding structure with the side fixing block 3 through the connecting shaft 404, and the gear plate 405 is symmetrically arranged with respect to the central axis of the outdoor door lock housing 1. This can stably limit the position of the side opening door 406 connected to the gear plate 405, thereby stably opening and closing the front of the outdoor door lock.

[0023] A sealing connection mechanism 5 is welded and installed on the outer surface of the automatic door opening mechanism 4. The sealing connection mechanism 5 includes a side connecting block 501, an abutment block 502, and a sealing gasket 503. The side connecting block 501 is welded and installed on one side of the outer surface of the side opening door 406. The abutment block 502 is welded and installed on the inner surface of the side connecting block 501. The sealing gasket 503 is bonded and installed on the inner surface of the abutment block 502. When not in use, the gear plate 405 is closed. When the gear plate 405 is brought close, the abutment block 502 installed on the outer wall of the side connecting block 501 can abut against the inner surface of the gear plate 405. At the same time, the sealing gasket 503 can seal the surface of the gear plate 405, thereby achieving the effect of dustproof and waterproof. The abutment block 502 is set with a concave structure and is symmetrically arranged with respect to the central axis of the outdoor door lock shell 1. This can stably seal the surface position of the gear plate 405, thereby avoiding misalignment during the sealing connection, which would affect the dustproof and waterproof effect of the outdoor door lock.

[0024] Working principle: First, the device is placed in the designated position. When unlocking, the rays generated by the infrared sensor 203 are refracted through the refractive plate 202, thereby sensing the position of the hand unlocking. The infrared sensor 203 is electrically connected to the drive motor 401, providing feedback to the drive motor 401. When the drive motor 401 is powered on, it drives the gear block 403 mounted on the outer wall of the rotating shaft 402 to rotate. The gear block 403 meshes with the gear plate 405, thus moving the gear plate 405 left and right. Simultaneously, the connecting shaft 4... 04. The inner wall of the side fixing block 3 is limited and connected, which can stably adjust the position of the gear plate 405, causing the gear plate 405 to open to the front of the outdoor door lock housing 1. At the same time, when not in use, the gear plate 405 is closed. When the gear plate 405 approaches, the abutment block 502 installed on the outer wall of the side connecting block 501 can abut against the inner surface of the gear plate 405. At the same time, the sealing gasket 503 can seal the surface of the gear plate 405, thereby achieving the effect of dustproof and waterproof. This completes the operation process of a dustproof and waterproof outdoor door lock.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
